As always Corbin, thanks for keeping us updated on all things Hyundai, Kia and Genesis Evs. Though I love my 2022 I5 Limited, like a lot of us I am getting tired of the trips to the dealer. At the dealer I bought my I5 from, it takes over a month for me to get a service appointment and I called just after seeing this video. First available appointment was January 3rd. Called another dealer who said middle of December. In October my 12 volt started to die (like a lot of us) and when I called the dealer they said I could bring it in for them to test it the following week, but made no promises about when they could replace it. I ended up buying the AGM Weize (works great thanks again Corbin) and installing it myself. I did reach out to customer care and they sent me a check for the battery.
I was at the dealership this morning for an already-scheduled regular maintenance, and when I checked in they mentioned the recall and offered to do it at the same time. I have fortunately not had any ICCU issues yet. All total I was there for about 2 1/2 hours, and the recall was completed successfully.
What exactly did they do? It sound's like it's a faulty ICCU (which is a large piece of hardware the size of a large King Size Pillow) is determined defective now, is not fixed via software, but a hardware change, that sound's rather involved, taking hours ????
Thanks! Just checked mine and there is another recall for this, I called to make an appointment at a local dealer and they said it’s not that urgent and I can book it after the holidays. Let’s hope! 🤞🏼
Mine is in the shop now. Never thought I would have to jump start an electric car in my garage. Was at 35% SOC when it died. Had to use an external jumping battery to start and drive the car to the tow that came to my house
Welcome to the club. I've had two different Ioniqs since December 2021 and this has been a 9 month ritual with the hope that this is the last time. Hopefully they will eventually have a final fix, but at the same time I love these cars so much that this being the only flaw to me feels like a blessing given the crapshoot that comes with buying 1st generation cars.
@ you are right. I do love the car and the newest update fixed the bad sound quality and that blew me away. So yes, even iPhones have to have massive updates so a car this innovative makes a little sense.
Perfect timing for our scheduled service appointment today for our Ioniq 5, hopefully the dealer only has to press the buttons. Question: is there any way to read the DTC codes ourselves without paying for the expensive special tablet the dealer has that HMG charges $5000 to get?
Just last week, I had my 2023 Ioniq5 12V battery replaced under warranty because it wouldn't hold a charge anymore after I used the compressor that was included with the car to inflate a slow leaking tire. They also did a recall that had something to do with Level 2 charging. I guess I'll have to take it in again. Nice that Hyundai is staying on top of this, but it sure would be nice if they could program those ICCUs over the air...
Hi, I saw this recall a few days ago on X and as you said X also stated Hyundai would not be sending out the recall until January. When I read that I just thought I'd wait. After watching your video I opened the app. and tried to schedule the recall. The first date it gave me was February 5 2025. I'm calling the dealer tomorrow. Thanks for a great video. I really love my Ioniq 5 and it's the first EV for me. I've had no issues thus far, but it is a 2024 and I've only had it since Sept. I'm 70 and my dad used to talk about horse and buggies and now I"m driving an electric car. What a great time we live in. Jon
What a coincidence. I just got my '22 I5 SEL back from the dealer after having the Iccu replaced. They had it 2 months and tried several different fixes (replace charger door!) before the final fix. Hyundai national got involved and worked with the dealer to find the final solution. I was given a brand new Sonata loaner and was reimbursed by national for the week's rental cost before they gave me the loaner. The problem announced itself when I tried to charge with my level 2 home charger. It would begin to charge and then 'click' the charging would halt. My local service dept was mostly unfamiliar with EV repairs, it seemed, so they depended on national to steer them to the solution. This was the first problem the car had given me in over 2 years. Hats off to national for making what could have been a real pain in ass into a mostly painless process. If this happens to your I5, go straight to national and request that they monitor the repair process. The dealer was Phillips Hyundai in Bradley, IL.
I am in the market for a used IONIQ 5 from the 2022 or 2023 model years, can you tell me what you mean by ''go National'' if my own local dealerships in Las Vegas, are also in the dark about how to fix the latest ICCU issues based on the latest re-call ?
it is so weird that my App was showing the notification that the car need to be taken to service and all of the sudden the notification dessapeared . I hope is a good sign and nothing is wrong.
We did both recall services--the last on 12/20--and our ICCU died on Jan. 7. In the shop, but the ICCU parts are "backordered" with no idea of how long that will be.
Hello Corbin , thanks for the update , I suspected another problem as my orange light on top of the dash is coming on a lot this will be the 3rd time for me , I have never had the 12 volt battery fail as of yet , but I do carry a small battery booster if needed to start the car. Thanks you again.
Ironically, my ICCU died 2 days after this recall was announced. Fortunately my dealer had one in stock, so it was fixed in 1 day. At least I managed to get the updated software at the same time!
Corbin, thank you for staying on top all our issues and presenting solutions. Really appreciate it. I just did the recall. In my case, there were no codes and they did the software update. My car was needing jumpstart over the past 2-3 weeks and the voltage went around 9.7V. Once it is running, voltage held around 13.5-14.3. Do you know how the 12V is charged while the car is being driven? Is that done by ICCU? I asked this to the service people at the dealership and they were throwing jumbo mumbo at me. So basically they are clueless. reason is, this past weekend i jumpstarted the car and drove it for 60 miles. I tried starting it back up after 15 minutes and the car was completely dead.
Had my car in for a service at 72,000km last week, did the update while there. In and out in 2 hours. Have had 0 issues with car.... Thanks for the heads up though! Mike and Ally 🇨🇦
Took my car in (Ioniq 5 2023) for this recall. There is also a VCU update now in regards to the limp home mode. It's considered a TSB, I believe, and not a recall. Came out a few days ago, and im getting it serviced now.
Had an ICCU and battery replacement a couple of weeks ago. At dealership this moment to have all terrain tires installed and was told of the latest update, which will be installed today. No idea of the changes. According to the dealer, the new battery is an AGM type.
I put a BMS on the OEM lead-acid 12-volt battery. It cycles once per day. 1) This is not normal. No wonder it does not last the typical 5 years as a typical “starting” lead-acid battery would. A deed-cycle battery instead of a starting battery would be a better fit for the 12-volt battery. 2) Regardless, something is draining this 12-volt battery. Therefore, I’d be real surprised if the ICCU charging is the root cause.
I just finished an eight service adventure with my 22 Ionic 5 RWD. It started with my inability to slow charge my Ionic5. It would charge DC (level 3) no problem but level 1 and 2 charging would not work. It would start the charge for about 10 seconds and then announce the charge "terminated". I took the car into my local Hyundai dealer 3 times over 3 weeks then, on my fourth visit they said they needed the vehicle on site so they could investigate further using external (national) resources. I was given a loaner. Finally following 6 weeks of work I was informed that the ICCU had to be replaced and this would require an addition 2 weeks of work and testing. I got my Ionic 5 back in full working order.
Thank you for posting this, I'm currently in the market for a used IONIQ 5, so I'm following all of this closely, but I'm confused still on what the latest recall still means: Does it appear in your opinion that if the dealership's determine your IONIQ 5 (either 2022 or 2023 model year) has some type of ICCU defect, it's more likely now, your getting a entirely new ICCU , right away , or do you still face an uphill battle with long drawn out software patches first?
My Hyundai dealer is on top of this. Last Friday I made an early December appointment for routine scheduled service and upon reviewing the appointment confirmation they had listed this recall automatically without me having to mention it, which is good since I didn't even know about it until now. Nice to see them being proactive.
Just got my letter after Christmas and have scheduled my appointment for the 2024 Ioniq 5. I bought mine for retirement. Sure glad I have time now to get it addressed!
I've had my 5N for about a month now. Two days ago the digital display went totally blank for about a second. Then came back on. This happened while I was doing about 70 on the highway. I'm pretty sure that the 5N will be included soon enough.
The blacked out display isn't a 12v issue. The root cause for a couple I've seen reported were caused by a failure to apply thermal gel to the heatsink on the gpu. One instance had a plastic film that was supposed to be removed, but wasn't, preventing proper cooling of the chip leading to periodic screen blackouts which recovered after the chip cooled enough.
FYI: The Kia EV9 uses a different system that has a really cool motor that is designed to reconfigure the internal windings between delta and wye. It does this on the fly to make it more efficient whether needing torque or high speeds. Check out the Munro Live tear down of the Kia EV9 motor for more information.
Had an issue with our GV60 sport 4 weeks ago. Orange light dash battery issue while leaving for home. Then a red battery warning telling us to stop the car in a safe place. I did get the car home in slow mode. Took the dealership 3 weeks to get a replacement iccu. Was given a Ford Mustang Mach E on day one until the car was ready. My only issue with Genesis UK was they were not proactive in telling us about how long they would need the car to repair it. All fixed now, I’m assuming they put the updated iccu in.
I can't believe it. We took our 2022 SEL in for the recall 14th December. Today (26th Jan) the ICCU failed. So angry. First tried taking to an Autozone to replace the battery, wasted $250 there because within 2 minutes of driving away the same warnings all started again. Given the cold weather and my car's 2.75 year age, I was sure it was just a dead battery, the fact a fresh battery immediately died proves it must be the apparently software fixed ICCU. Now my car is stuck there and the service garage is 40 miles away and closed on Sundays anyway, so I'll have to get another tow tomorrow..... sigh
Corbin, My ICCU has been updated and my 12v was replaced last Feb. I am concerned. Is it normal for my 12v charge indicator light to be on very frequently? It seems crazy that the ICCU needs to tend to the 12v so much.
EV6 GT was in on Wednesday and that too just needed the software update, out in about an hour, no drama. Putnam KIA in the Bay Area has generally been a good experience if you need a dealer who knows what they are doing.
I got the update yesterday along with the fuse changed and charged today to 97% and only 276 miles range listed. I have the SEL trim and always got up to 350 miles on full charge. Something is off about this update.
I never had any problems charging my 2023 Ioniq 6 at a Super Charging station or at home with my Emporia Level 2 charger. However I have installed all Softwesr upgrades. I learned of this issue on Nov. 23 and was able to schedule an appointment on Nov. 26. Thank You!
I'm in the US, and just had my recall handled today (2024 Limited). It took two hours. They said the time depended on their network bandwidth to download the software fix. The repair order showed that they did not have to replace the ICCU (quantity zero for part 36400-1XAA0-QQH, ICCU ASSY). They ordered a high-voltage fuse (375F2-GI040-QQH), which I assume I'll have to come back to have replaced. My service advisor gave me two tips: don't park the car with less than 20% battery unless you start charging it right away (so that the 12V battery doesn't go dead), and also to turn the headlights on during the daytime. This drains the 12V battery, which triggers the drive battery to recharge it and keep it healthy. He also warned against car washes that clean the undercarriage, because that's where the big battery lives. He says it's well-protected, but still... Great advice!
My 2022 Ioniq 5 with 36k miles suddenly stopped charging. Went to another charger to rule out my home charger being bad. Car says “charging unsuccessful”. Tried driving it and plugging in later, no change. The only Hyundai dealer who has EV mechanic is 40+ miles away and I have enough power to get me there for an appnt Friday. I have updated all recalls already. Anyone know about this issue? Thank you Corbin. I have depended on you since I got this car since I have no knowledge of EVs and am challenged enough by technology in general. My previous 15 year old Subaru had zero tech! Grateful for any info, Cheryl
What a coinkidink!! I just got home from dropping off my '24 Ioniq 5 for that recall. I didn't get any notice of it. I was there for a previous recall on the tire inflator kit that they didn't get replaced due to our hurricanes. They said they could start right away on the ICCU work but might not finish it today since it was early afternoon when I dropped off the car. I think they jumped on it right away because they were a little embarrassed at having dropped the ball on the inflator recall. 🤫 I've never had any issues with the ICCU and have 12,300 miles on it since buying it in April. Thanks for all the details and have a great Thanksgiving!
Update: I had the latest ICCU recall done yesterday. It's the 272 campaign. They checked for codes (none found), checked the fuse (OK), and updated the software. I've only driven it the two miles home from the dealer so far. I checked my BM2 data just now and it looks perfectly normal. On a side note, I'm pretty impressed by these folks. They actually have three EV certified techs and they have treated me great even though they're in the middle of a major remodeling project.
@@jerrymildredpetersen3177 Hmm--I called my dealer here in Minnesota and they said they did not have the 272 software patch as yet and that it could take up to 30 days. I hope they updated your software with the new patch. Funny that this cannot be done remotely?
@@MrHockey1720-G Corbin said all dealers know about it, but I don't think they all dealers get updates right away. Some might not get it till January when Hyundai mails out letters to affected owners. My local dealer sells lots of EVs, so they probably get first dibs on that stuff. I didn't go in asking for it, but they told me I was "on the list." When they are ready to do yours, you'll know by going to the service scheduling page in your Hyundai app. There will be a bright red banner saying you have an active recall. It's shown at 2:09 in Corbin's video. Plus, my dealer paperwork says it was campaign 272. Hyundai, like most if not all legacy auto makers does not do OTA updates for anything but navigation and infotainment. Maybe someday, but I'd sure hate to get halfway through an OTA update and have a communications fault that bricks my car. It's bad enough when that happens with computers.
@@jerrymildredpetersen3177 Good points. I told my sales person about what I was told and he texted me and said that she is in a call center and doesn't have the best info. He scheduled me for service next week to address Recall Campaign 272.
I had the recall done on Jan.4th, 20256, but I'm reading some comments on the I5 FB page about a software issue that can cause the ICCU to fail after the recall, and that Hyundai has ordered the recalls halted! Wuddup wit dat?
We had this recall done on our Ioniq 5 Ltd AWD this morning, and our dealer took less than two hours to complete it (just needed the software update, no ICCU DTC)
If one buys a used eGMP car that has been previously been recalled/reacquired by manufacturer for ICCU related issue - is it still eligible for subsequent recalls like this one? There are spicy
Hi. Had the ICCU checked. at Kia before it was purchased this summer. After a long trip, my 2022 ev6 ICCU popped, heard the fuse pop. Drove it to the dealer immediately and they confirmed the ICCU and fuse needed to be replaced. Has the failure been associated with temperature or fast charging. Did fast charge this trip…. Thanks.
They'll only replace it if it's showing signs of a problem at least they are checking it for free each time. It would take years to replace them all with your car being in the shop for a while possibly getting something it doesn't need while they up the prices of everything to pay for such a recall.
My ICCU experience with my '23 Ioniq 5 - both software updates done, the second just two weeks ago with no indication anything was wrong with the ICCU itself. Then, just last week the dreaded "Check Electrical System" warning. Fortuneately I was close to home and was able to limp home. But the OEM 12v battery was DEA. Charger would not bring it back to life, so a new battery was necessary in order to get the car out of the garage. A tow to the dealer and a replacement for the ICCU followed. All seems good now, although I haven't observed the new 12v being charged. I sure hope this is the end of this.
Have to say the last ICCU fix was simple and brief, did it during a tire rotation. Hopefully this one will be the same. I've had no problems with my 2023 Ioniq 5 12V battery so far.
My I5 2023 wouldn't get charged after fixing recalled. I had to go back to dealer and had them check and ICCU needed to be replaced. I need to wait until the end of month to get fix and no loaner available. Maybe y next problem for this car is 12V
Interestingly enough, I did the same as many, got the first update done. Within weeks the next recall came out. I needed to drive over 200 miles for work and charged at a charge point. It puts out over 40kw, and sure enough a day later I ended up doing a remote climate start. My Wallbox reports the car abruptly disconnecting charging and the whole thing is dead. Read an article saying if charging above 40kw it may destroy the iccu. If this is even remotely true it’s ridiculous. I believe these cars support 800v charging. How even for my 2023 is this still a problem when this goes back YEARS. Anyway, now waiting for the part that no one knows when it’ll arrive.
My Kia Soul EV had the battery pack replaced under warranty due to a defect, so I have the ICCM recall as well. My car arrived at the dealer for the recall the Friday before this new recall, so, yeah, they still have it. *sigh*
This is good information. I am learning about all the cars and their issues now so that when we replace my wife's ICE car I'll know what issues each car has because I plan on buying used. It looks like Hyundai and Kia are out. It was bever going to be a Tesla. Maybe a Mach-e?
Well Corbin, got my ICCU recall software update today, I hope this fixes it! It took just a few hours, including the shuttle service back home, and back to Hyundai. I have had no issues with my 2023 Ioniq 5 SEL AWD, and the time before I had them put an AGM battery in. I figured that that would be the best for Midwest climates. I didn’t wanna chance it with that lead acid battery, especially since the car was manufactured in late 2022 🤷🏻 🤞
I definitely agree the service stuff is getting old! All of the three local Kia dealers in the SLC area have crazy long wait times to get an appointment, plus our cars have gone in for various recalls already. Hopefully this is the fix!
Unfortunately, I have the same issue in NY. I dread if something goes wrong with my wife’s Hyundai. At least two weeks to wait for an appointment and no loaner cars! Frustrating. Ford is a little better but not by much.
I had to recently replace the 12V battery after 2.5 years. Was this caused by the problem caused by this recall? Can I get the dealer to pay for my battery?
I have a ‘23 IONIQ 5 with dead batteries and two tows to the dealership. They said the ICCU software was fine but apparently the software the dealer has doesn’t do a “deep analysis”. Anyways, Hyundai corporate said thousands of people have this issue and one of the dealerships I talked to said they would never buy an EV - odd, since they sell them. I am being told the charger port needs to be replaced and it is on a 2 week national back order. This is my first and last Hyundai - they don’t stand behind their vehicles and their dealers clearly don’t like EV’s.
Yes, I was hesitant but someone that works in engineering at Hyundai told me that it would be fine with an AGM and I think the months of using one have proven that accurate
@ oddly, the battery you linked on Amazon says it doesn’t fit the Ioniq 5 if you use their vehicle fitment software… yet other AGM batteries of the same Group Size do. Weird.
I replaced my OEM battery with an AGM battery, will that void my warranty? If it's an issue I can put the OEM battery back in. With the OEM battery, the charge light is on a lot.
I don't see anything in KIA Connect for my 2023 EV6 yet. Hopefully I will get a notice in the mail like last time. I also have a voluntary service campaign relating to the charging port that I've been putting off. My ICCU was already replaced in June.
It seems like every 6 months that I have scheduled service due with my GV60 there is yet again another recall. The upside is that Genesis still picks up my car and leaves me a loaner at my convenience so no real skin off my nose at least while I still have warranty coverage. I suspect I will be cutting the car loose at that point if they can't get their recalls under control. Last service visit I asked my service advisor about any resolution to the AC charge port overheating issue, nope, apparently Hyundai still working on it. Really its been 2 years. I kind of feel like they are tossing out questionably useful software band aids for clearly significant hardware problems and hoping it buys they more time to kick the can further down the road.
Ioniq 5 owner here. Sadly I think you’re right. They’re just giving band aids to cover up serious problems. We are in a hot country (Australia) and we can’t AC charge at full current as the car will overheat. 4kW AC charging is embarrassing.
Always something with my G70, too.. I finally said screw it and ditched Hyundai Child Labor Group, altogether. Looking at EVs, but not looking here lol
I have an Ioniq5 2023 limited RWD, I have taken the vehicle into Hyundai dealership on previous recall. Do I still need to schedule another appointment to go for the same issue if it was already taken care of the first time? I mean if it's not broke don't fix it, right. I don't want to take it in and all of a sudden I have issues now.
It's not on sale yet in the US. The cars that have been sold likley wouldn't see a recall until months of sales and anything pointing that there is an issue.
Saw the recall on my new ioniq 6 (purchased October 30, 2024). Scheduled a service time and then waited almost 4 hours for the update to be completed. I can't beleive that a software update can take almost 4 hours but the dealer said they were haveing truouble and it just takes time. With over the air updates now a regular event what a flubber f***k having to wait in a dealers crapper waiting room. If you take your car in be sure to have someone pick you up so you don't have to waist half a day.
I had to buy a portable Jump starter bc I kept getting the fail safe 12v low voltage error, after getting BOTH my I5’s towed to the dealer for them to tell me the battery was fine. Lucky I have a tire swap scheduled for tomorrow, so hoping they can take care of this quickly. Oh and the iccu on my 22 SEL failed and was replaced this year as well. Peeved but still love the car
Just had my service done and asked about said recall. Service advisor had no ideal but had patience and boom found it checked with service tech to ensure they could perform it. Boom took almost 2hrs but it was done. Never had any issues even for the first recall. Fingers crossed don’t have this. Only issue I had was the added miles to get the first recall done. It a lease and Hyundai finance doesn’t give you credit for those miles incurred 😡.
I thought I saw that the Ionia 5 2025 is not in the recall. Is this true ?if so is that because it is not for sale yet or was it was fixed in production??
Does anyone know if the issue is actually truly fixed? After doing both recalls my ICCU failed. I want to lemon the car at this point as I don’t trust that the issue is actually fixed even if new part is put in.
Yup my 2023 I5 is not quite 2 years old and the ICCU failed on the highway just a week after the "dead 12v battery" was replaced. Also, the dealer service person admitted that my problem with occasional errors in shifting could be due to the faulty ICCU (turn knob to R and it occasionally decides to go to D).
I had the I5 updated and fixed all recall and a week after, it didn't take charge anymore. Luckily I have 20% left to get to dealer and now I have to wait until the end of the month to get ICCU Replaced without a loaner. I'm getting tired of this car event it very smooth to drive.
Really sorry to see this repeat debacle. I was the proud owner of an Ioniq 5 until seeing the first ICCU issue, at which point I pulled the plug and went Model Y. I loathe Musk, but hate being without a car even more so.
My ICCU went wrong and the car was flat bedded. With the new ICCU there is a really irritating high pitched whine. It is loud enough that I can hear it over the radio. Haven't taken it back yet but I do hope I'm not going to be fed a load of denial bull.
My car went into Turtle mode! Before the 12v battery warning popped up. I had to get roadside assistance. Dropped off my 2022 IONIC 5. They have to replace the ICCU! I called Hyundai customer service to follow up on cost for a rental vehicle. Now I am waiting for the parts and installation. Seriously how annoying!
I called the dealer that sold me the 2024 Ioniq 5 last week and they said that they do not have a software fix and that it could take up to 30 days to receive one. I'm calling again next week.
@theioniqguy my Kia EV6 passed and was addressed for ICCU update check.. pre 100K miles then at 102k miles it fails. If you can help me get this addressed and fixed thanks. Don’t pigeon whole yourself to one brand. You review cars the Ioniq 5 got you excited Best wishes 🎉
I didn't see the Ioniq 5N listed as an affected vehicle either. Unless it's considered to be an Ioniq 5 (I feel like it's often listed as a different car but maybe they just consider it a trim level).
I saw a person with a brand new EV9 at a charging spot in Canada a couple of weeks ago and they had to call roadside assistance for a dead 12v, road side brought a jumper while I was there. He told me he left the car with a low charge overnight. So I'd be surprised if the issue isn't also present on the EV9.
If it just needs a software update you can wait for it. But if they find the ICCU needs replacement that will take much longer. Unfortunately there’s no way to know until they actually run the diagnostic.
Do you have the Hyundai recall pdf that would list the new ICCU version number? I need that before going into my dealer. Last time when I went in for the VCMS L2 charging fix, they claimed there was no update available and marked the campaign as completed. I had to raise hell as the software version was still the old one. They finally took me in the back and showed me on their tablet where it popped up in auto mode but supposedly the tech was trained to ignore and go into manual mode and did not see anything. Basically had to show the tech and service manager how to do the update lol.
That is awful, I'm fearing the worst outcome and experience if this happens to me, any headway on your PDF ICCU version new # to pass that along to my own dealer or at a minimum double-check they know what they're doing?
Dealership likely won't install anything that's not theirs. Any other shop would do it. If you bought an AGM from any auto parts store, they'll likely install it for free.
@ great. Thanks for the reply I thought it may need some technical fix or attachment with the high voltage battery. I am based in Australia. Recently got my ICCU fixed. Would change my 12v battery now and will be using BMS to keep an eye on 12V battery. Hope we get the 2nd recall soon in Australia and this ICCU issue gets sorted for ever
Hi, I got my UK version Model Year 2025 (MY25) IONIQ 5 N Line S AWD last week. It’s great. With a rear windscreen wiper! I bought a magnetic sunglasses holder and a charging port lights blocker from you on Etsy. The sunglasses holder is great, but the item to hide the lights during charging does not (a) cover the newly-designed charger lights, and (b) won’t fit anywhere when you close the charge door… it’s just not the right shape for the new design. MY25 items from your on-line shop will need to be amended/redesigned to fit. Thought you’d like to know. Jim
I had my ICCU replaced earlier this year after it unexpectedly went pop from the rear seat and I got as far as my 12v battery lasted. I was off the road for 6 weeks as parts were sourced. I think the clock is ticking on all of them.. I feel sooner or later they all need to be fully replaced.
I’ve had absolutely no problems with my 2022 Ioniq 5 Limited until last week. (I purchased the car in June 2020.) I was taking my wife to the hospital for surgery when I received the notice to check the car’s electrical system. The car soon went into turtle mode but I was able to get it back home and use our other car for the hospital trip. I’ve made an appointment with my Hyundai dealer for Monday to have the car fixed. Sure hope this is the last time we have to deal with this issue. Good luck to everyone and, based on my experience, I wouldn’t wait to have your cars serviced. Update 12/5: I had the car towed to the dealer on the morning of 12/2 and was told they would diagnose the problem by the end of day. I decided not to wait and the dealer provided an Uber ride home. I received a call later saying that the ICCU unit needed to be replaced, so I arranged for another Uber ride back to the dealer and they provided a loaner car. The ICCU unit was shipped to the dealer on 12/4 and the recall was completed that afternoon. I was expecting a much longer wait for the part to arrive. Great service from CardinaleWay Hyundai in Glendora California.

I have seen most of Your posts and have found them to be very informative and helpful.
As always Corbin, thanks for keeping us updated on all things Hyundai, Kia and Genesis Evs. Though I love my 2022 I5 Limited, like a lot of us I am getting tired of the trips to the dealer. At the dealer I bought my I5 from, it takes over a month for me to get a service appointment and I called just after seeing this video. First available appointment was January 3rd. Called another dealer who said middle of December.
In October my 12 volt started to die (like a lot of us) and when I called the dealer they said I could bring it in for them to test it the following week, but made no promises about when they could replace it. I ended up buying the AGM Weize (works great thanks again Corbin) and installing it myself. I did reach out to customer care and they sent me a check for the battery.
Thanks for the update and by the way I watched you on the Out of Spec race across the country it was a fun and educating video great job.
I was at the dealership this morning for an already-scheduled regular maintenance, and when I checked in they mentioned the recall and offered to do it at the same time. I have fortunately not had any ICCU issues yet. All total I was there for about 2 1/2 hours, and the recall was completed successfully.
What exactly did they do? It sound's like it's a faulty ICCU (which is a large piece of hardware the size of a large King Size Pillow) is determined defective now,
is not fixed via software, but a hardware change, that sound's rather involved, taking hours ????
I experienced this issue last week, and then a few days later, the recall was issued. I did the software update recall a few months ago.
I scheduled the service for it and luckily my dealership put me in for their earliest appointment……in mid January.
Thanks for the detailed update! I'll call my dealer and see if they can do this update before Christmas.
Thanks! Just checked mine and there is another recall for this, I called to make an appointment at a local dealer and they said it’s not that urgent and I can book it after the holidays. Let’s hope! 🤞🏼
Mine is in the shop now. Never thought I would have to jump start an electric car in my garage.
Was at 35% SOC when it died. Had to use an external jumping battery to start and drive the car to the tow that came to my house
I saw this recall on TikTok lol. It is getting annoying to have to do this 2x in one year…
Welcome to the club. I've had two different Ioniqs since December 2021 and this has been a 9 month ritual with the hope that this is the last time. Hopefully they will eventually have a final fix, but at the same time I love these cars so much that this being the only flaw to me feels like a blessing given the crapshoot that comes with buying 1st generation cars.
@ you are right. I do love the car and the newest update fixed the bad sound quality and that blew me away. So yes, even iPhones have to have massive updates so a car this innovative makes a little sense.
Thanks for keeping us updated! Appreciate your work. Hope L.A. Auto Show was good. Any videos from that?
Perfect timing for our scheduled service appointment today for our Ioniq 5, hopefully the dealer only has to press the buttons. Question: is there any way to read the DTC codes ourselves without paying for the expensive special tablet the dealer has that HMG charges $5000 to get?
eg, can this DTC code that leads to ICCU replacement be seen in Car Scanner?
Corbin, I took your advice a long time ago to keep my SOC greater than 20% where possible. It's been 1 year, no issues. Ioniq 6 SE AWD.
Just last week, I had my 2023 Ioniq5 12V battery replaced under warranty because it wouldn't hold a charge anymore after I used the compressor that was included with the car to inflate a slow leaking tire. They also did a recall that had something to do with Level 2 charging. I guess I'll have to take it in again. Nice that Hyundai is staying on top of this, but it sure would be nice if they could program those ICCUs over the air...
Hi, I saw this recall a few days ago on X and as you said X also stated Hyundai would not be sending out the recall until January. When I read that I just thought I'd wait. After watching your video I opened the app. and tried to schedule the recall. The first date it gave me was February 5 2025. I'm calling the dealer tomorrow. Thanks for a great video. I really love my Ioniq 5 and it's the first EV for me. I've had no issues thus far, but it is a 2024 and I've only had it since Sept. I'm 70 and my dad used to talk about horse and buggies and now I"m driving an electric car.
What a great time we live in.
Jon
Got mine for Mt ev6. Had it in for service because charging fails when I try and run the climate, and had then run the update too.
Thank you for the heads up! I am about to pick up an Ioniq 5, I will make sure the dealership looks into this before I drive it off the lot.
They’re legally required to install the update before you can purchase the car
@@TheIoniqGuy Oh awesome, I hope that applies to Canada as well. I sent off an email just in case. Thanks again!
@@tunnagan Canada has it out. Book an appointment with your Dealership now.
Thanks!
Thank you so much!
What a coincidence. I just got my '22 I5 SEL back from the dealer after having the Iccu replaced. They had it 2 months and tried several different fixes (replace charger door!) before the final fix. Hyundai national got involved and worked with the dealer to find the final solution. I was given a brand new Sonata loaner and was reimbursed by national for the week's rental cost before they gave me the loaner. The problem announced itself when I tried to charge with my level 2 home charger. It would begin to charge and then 'click' the charging would halt. My local service dept was mostly unfamiliar with EV repairs, it seemed, so they depended on national to steer them to the solution. This was the first problem the car had given me in over 2 years. Hats off to national for making what could have been a real pain in ass into a mostly painless process. If this happens to your I5, go straight to national and request that they monitor the repair process. The dealer was Phillips Hyundai in Bradley, IL.
I am in the market for a used IONIQ 5 from the 2022 or 2023 model years, can you tell me what you mean by ''go National'' if my own local dealerships in Las Vegas, are
also in the dark about how to fix the latest ICCU issues based on the latest re-call ?
it is so weird that my App was showing the notification that the car need to be taken to service and all of the sudden the notification dessapeared . I hope is a good sign and nothing is wrong.
We did both recall services--the last on 12/20--and our ICCU died on Jan. 7. In the shop, but the ICCU parts are "backordered" with no idea of how long that will be.
Hello Corbin , thanks for the update , I suspected another problem as my orange light on top of the dash is coming on a lot this will be the 3rd time for me , I have never had the 12 volt battery fail as of yet , but I do carry a small battery booster if needed to start the car. Thanks you again.
Ironically, my ICCU died 2 days after this recall was announced. Fortunately my dealer had one in stock, so it was fixed in 1 day. At least I managed to get the updated software at the same time!
Corbin, thank you for staying on top all our issues and presenting solutions. Really appreciate it. I just did the recall. In my case, there were no codes and they did the software update. My car was needing jumpstart over the past 2-3 weeks and the voltage went around 9.7V. Once it is running, voltage held around 13.5-14.3. Do you know how the 12V is charged while the car is being driven? Is that done by ICCU? I asked this to the service people at the dealership and they were throwing jumbo mumbo at me. So basically they are clueless. reason is, this past weekend i jumpstarted the car and drove it for 60 miles. I tried starting it back up after 15 minutes and the car was completely dead.
My battery was at exactly the same voltage and was replaced, but it took them keeping it for a few days to have the battery die after charging it.
Had my car in for a service at 72,000km last week, did the update while there. In and out in 2 hours.
Have had 0 issues with car....
Thanks for the heads up though!
Mike and Ally 🇨🇦
Took my car in (Ioniq 5 2023) for this recall. There is also a VCU update now in regards to the limp home mode. It's considered a TSB, I believe, and not a recall. Came out a few days ago, and im getting it serviced now.
Had an ICCU and battery replacement a couple of weeks ago. At dealership this moment to have all terrain tires installed and was told of the latest update, which will be installed today. No idea of the changes. According to the dealer, the new battery is an AGM type.
I put a BMS on the OEM lead-acid 12-volt battery. It cycles once per day. 1) This is not normal. No wonder it does not last the typical 5 years as a typical “starting” lead-acid battery would. A deed-cycle battery instead of a starting battery would be a better fit for the 12-volt battery. 2) Regardless, something is draining this 12-volt battery. Therefore, I’d be real surprised if the ICCU charging is the root cause.
I just finished an eight service adventure with my 22 Ionic 5 RWD. It started with my inability to slow charge my Ionic5. It would charge DC (level 3) no problem but level 1 and 2 charging would not work. It would start the charge for about 10 seconds and then announce the charge "terminated". I took the car into my local Hyundai dealer 3 times over 3 weeks then, on my fourth visit they said they needed the vehicle on site so they could investigate further using external (national) resources. I was given a loaner. Finally following 6 weeks of work I was informed that the ICCU had to be replaced and this would require an addition 2 weeks of work and testing. I got my Ionic 5 back in full working order.
Thank you for posting this, I'm currently in the market for a used IONIQ 5, so I'm following all of this closely, but I'm confused still on what the latest recall still means:
Does it appear in your opinion that if the dealership's determine your IONIQ 5 (either 2022 or 2023 model year) has some type of ICCU defect, it's more likely now,
your getting a entirely new ICCU , right away , or do you still face an uphill battle with long drawn out software patches first?
@flolou8496 Hyundai is now investigating all 22, 23 Ionic 5 s for this issue.
My Hyundai dealer is on top of this. Last Friday I made an early December appointment for routine scheduled service and upon reviewing the appointment confirmation they had listed this recall automatically without me having to mention it, which is good since I didn't even know about it until now. Nice to see them being proactive.
Hopefully they will have the software patch by then. I called today and they don't have it.
Just got my letter after Christmas and have scheduled my appointment for the 2024 Ioniq 5. I bought mine for retirement. Sure glad I have time now to get it addressed!
Seems as though the ioniq5N isn’t included? Perhaps because it is a 2025 MY and uses different parts?
I've had my 5N for about a month now. Two days ago the digital display went totally blank for about a second. Then came back on. This happened while I was doing about 70 on the highway. I'm pretty sure that the 5N will be included soon enough.
i'm wondering the same... :/
The blacked out display isn't a 12v issue. The root cause for a couple I've seen reported were caused by a failure to apply thermal gel to the heatsink on the gpu. One instance had a plastic film that was supposed to be removed, but wasn't, preventing proper cooling of the chip leading to periodic screen blackouts which recovered after the chip cooled enough.
Logged on to Hyundai's site this morning and booked an appointment for tomorrow in Albany, NY.
FYI: The Kia EV9 uses a different system that has a really cool motor that is designed to reconfigure the internal windings between delta and wye. It does this on the fly to make it more efficient whether needing torque or high speeds. Check out the Munro Live tear down of the Kia EV9 motor for more information.
I don’t see a recall listed for my EV6. Do you know if this is necessary if I already had the ICCU replaced?
Considering this car. Not buying until they fix this.
This vehicle has failed on me twice. I’m done with it. 2022 Limited, 49k miles
Had an issue with our GV60 sport 4 weeks ago. Orange light dash battery issue while leaving for home. Then a red battery warning telling us to stop the car in a safe place. I did get the car home in slow mode. Took the dealership 3 weeks to get a replacement iccu. Was given a Ford Mustang Mach E on day one until the car was ready. My only issue with Genesis UK was they were not proactive in telling us about how long they would need the car to repair it. All fixed now, I’m assuming they put the updated iccu in.
I can't believe it. We took our 2022 SEL in for the recall 14th December. Today (26th Jan) the ICCU failed. So angry. First tried taking to an Autozone to replace the battery, wasted $250 there because within 2 minutes of driving away the same warnings all started again. Given the cold weather and my car's 2.75 year age, I was sure it was just a dead battery, the fact a fresh battery immediately died proves it must be the apparently software fixed ICCU. Now my car is stuck there and the service garage is 40 miles away and closed on Sundays anyway, so I'll have to get another tow tomorrow..... sigh
Corbin, My ICCU has been updated and my 12v was replaced last Feb. I am concerned. Is it normal for my 12v charge indicator light to be on very frequently? It seems crazy that the ICCU needs to tend to the 12v so much.
I’m wondering if I should just wait for the letter. Sounds like there is a history of not getting it right the first time.
EV6 GT was in on Wednesday and that too just needed the software update, out in about an hour, no drama. Putnam KIA in the Bay Area has generally been a good experience if you need a dealer who knows what they are doing.
I got the update yesterday along with the fuse changed and charged today to 97% and only 276 miles range listed. I have the SEL trim and always got up to 350 miles on full charge. Something is off about this update.
The estimated range was reset due to the 12V being disconnected. Give it a week to readjust to your driving again.
In the EU we had 2 already. If this reaches our shores, it'll be the 3rd one...
I never had any problems charging my 2023 Ioniq 6 at a Super Charging station or at home with my Emporia Level 2 charger. However I have installed all Softwesr upgrades. I learned of this issue on Nov. 23 and was able to schedule an appointment on Nov. 26. Thank You!
I'm in the US, and just had my recall handled today (2024 Limited). It took two hours. They said the time depended on their network bandwidth to download the software fix. The repair order showed that they did not have to replace the ICCU (quantity zero for part 36400-1XAA0-QQH, ICCU ASSY). They ordered a high-voltage fuse (375F2-GI040-QQH), which I assume I'll have to come back to have replaced.
My service advisor gave me two tips: don't park the car with less than 20% battery unless you start charging it right away (so that the 12V battery doesn't go dead), and also to turn the headlights on during the daytime. This drains the 12V battery, which triggers the drive battery to recharge it and keep it healthy.
He also warned against car washes that clean the undercarriage, because that's where the big battery lives. He says it's well-protected, but still... Great advice!
This recall applies to Canada as well.
Happy Thanksgiving to you, your family, and all of my American I6 enthusiasts!
My 2022 Ioniq 5 with 36k miles suddenly stopped charging. Went to another charger to rule out my home charger being bad. Car says “charging unsuccessful”. Tried driving it and plugging in later, no change. The only Hyundai dealer who has EV mechanic is 40+ miles away and I have enough power to get me there for an appnt Friday. I have updated all recalls already. Anyone know about this issue? Thank you Corbin. I have depended on you since I got this car since I have no knowledge of EVs and am challenged enough by technology in general. My previous 15 year old Subaru had zero tech! Grateful for any info, Cheryl
Getting my 7500 miles tire rotation for the Ioniq 6 SE AWD in December so all good.
Thanks, Corbin!
What a coinkidink!! I just got home from dropping off my '24 Ioniq 5 for that recall. I didn't get any notice of it. I was there for a previous recall on the tire inflator kit that they didn't get replaced due to our hurricanes. They said they could start right away on the ICCU work but might not finish it today since it was early afternoon when I dropped off the car. I think they jumped on it right away because they were a little embarrassed at having dropped the ball on the inflator recall. 🤫
I've never had any issues with the ICCU and have 12,300 miles on it since buying it in April.
Thanks for all the details and have a great Thanksgiving!
Update:
I had the latest ICCU recall done yesterday. It's the 272 campaign. They checked for codes (none found), checked the fuse (OK), and updated the software. I've only driven it the two miles home from the dealer so far. I checked my BM2 data just now and it looks perfectly normal.
On a side note, I'm pretty impressed by these folks. They actually have three EV certified techs and they have treated me great even though they're in the middle of a major remodeling project.
@@jerrymildredpetersen3177 Hmm--I called my dealer here in Minnesota and they said they did not have the 272 software patch as yet and that it could take up to 30 days. I hope they updated your software with the new patch. Funny that this cannot be done remotely?
@@MrHockey1720-G Corbin said all dealers know about it, but I don't think they all dealers get updates right away. Some might not get it till January when Hyundai mails out letters to affected owners. My local dealer sells lots of EVs, so they probably get first dibs on that stuff. I didn't go in asking for it, but they told me I was "on the list." When they are ready to do yours, you'll know by going to the service scheduling page in your Hyundai app. There will be a bright red banner saying you have an active recall. It's shown at 2:09 in Corbin's video. Plus, my dealer paperwork says it was campaign 272.
Hyundai, like most if not all legacy auto makers does not do OTA updates for anything but navigation and infotainment. Maybe someday, but I'd sure hate to get halfway through an OTA update and have a communications fault that bricks my car. It's bad enough when that happens with computers.
@@jerrymildredpetersen3177 Good points. I told my sales person about what I was told and he texted me and said that she is in a call center and doesn't have the best info. He scheduled me for service next week to address Recall Campaign 272.
I had the recall done on Jan.4th, 20256, but I'm reading some comments on the I5 FB page about a software issue that can cause the ICCU to fail after the recall, and that Hyundai has ordered the recalls halted! Wuddup wit dat?
EV9 might be excluded because it already has CCnC from the beginning and my update it’s ICCU over the air?
We had this recall done on our Ioniq 5 Ltd AWD this morning, and our dealer took less than two hours to complete it (just needed the software update, no ICCU DTC)
Glad to hear no hardware replacement needed!
If one buys a used eGMP car that has been previously been recalled/reacquired by manufacturer for ICCU related issue - is it still eligible for subsequent recalls like this one?
There are spicy
Hi. Had the ICCU checked. at Kia before it was purchased this summer. After a long trip, my 2022 ev6 ICCU popped, heard the fuse pop. Drove it to the dealer immediately and they confirmed the ICCU and fuse needed to be replaced. Has the failure been associated with temperature or fast charging. Did fast charge this trip…. Thanks.
They need to just recal and swap every iccu for a revised version
They'll only replace it if it's showing signs of a problem at least they are checking it for free each time. It would take years to replace them all with your car being in the shop for a while possibly getting something it doesn't need while they up the prices of everything to pay for such a recall.
My ICCU experience with my '23 Ioniq 5 - both software updates done, the second just two weeks ago with no indication anything was wrong with the ICCU itself. Then, just last week the dreaded "Check Electrical System" warning. Fortuneately I was close to home and was able to limp home. But the OEM 12v battery was DEA. Charger would not bring it back to life, so a new battery was necessary in order to get the car out of the garage. A tow to the dealer and a replacement for the ICCU followed. All seems good now, although I haven't observed the new 12v being charged. I sure hope this is the end of this.
Have to say the last ICCU fix was simple and brief, did it during a tire rotation. Hopefully this one will be the same. I've had no problems with my 2023 Ioniq 5 12V battery so far.
My I5 2023 wouldn't get charged after fixing recalled. I had to go back to dealer and had them check and ICCU needed to be replaced. I need to wait until the end of month to get fix and no loaner available. Maybe y next problem for this car is 12V
Interestingly enough, I did the same as many, got the first update done. Within weeks the next recall came out. I needed to drive over 200 miles for work and charged at a charge point. It puts out over 40kw, and sure enough a day later I ended up doing a remote climate start. My Wallbox reports the car abruptly disconnecting charging and the whole thing is dead.
Read an article saying if charging above 40kw it may destroy the iccu. If this is even remotely true it’s ridiculous. I believe these cars support 800v charging. How even for my 2023 is this still a problem when this goes back YEARS. Anyway, now waiting for the part that no one knows when it’ll arrive.
Have fun in Philly. My Fair, Native City. Eat a Cheesesteak for me. Now I live in Winston-Salem, North Carolina.
My Kia Soul EV had the battery pack replaced under warranty due to a defect, so I have the ICCM recall as well. My car arrived at the dealer for the recall the Friday before this new recall, so, yeah, they still have it. *sigh*
This is good information. I am learning about all the cars and their issues now so that when we replace my wife's ICE car I'll know what issues each car has because I plan on buying used. It looks like Hyundai and Kia are out. It was bever going to be a Tesla. Maybe a Mach-e?
Well Corbin, got my ICCU recall software update today, I hope this fixes it!
It took just a few hours, including the shuttle service back home, and back to Hyundai.
I have had no issues with my 2023 Ioniq 5 SEL AWD, and the time before I had them put an AGM battery in. I figured that that would be the best for Midwest climates.
I didn’t wanna chance it with that lead acid battery, especially since the car was manufactured in late 2022 🤷🏻 🤞
I definitely agree the service stuff is getting old! All of the three local Kia dealers in the SLC area have crazy long wait times to get an appointment, plus our cars have gone in for various recalls already. Hopefully this is the fix!
Unfortunately, I have the same issue in NY. I dread if something goes wrong with my wife’s Hyundai. At least two weeks to wait for an appointment and no loaner cars! Frustrating. Ford is a little better but not by much.
I had to recently replace the 12V battery after 2.5 years. Was this caused by the problem caused by this recall? Can I get the dealer to pay for my battery?
Can you manually charge the 12-volt battery using a trickle charger?
Yeah
I have a ‘23 IONIQ 5 with dead batteries and two tows to the dealership. They said the ICCU software was fine but apparently the software the dealer has doesn’t do a “deep analysis”. Anyways, Hyundai corporate said thousands of people have this issue and one of the dealerships I talked to said they would never buy an EV - odd, since they sell them. I am being told the charger port needs to be replaced and it is on a 2 week national back order. This is my first and last Hyundai - they don’t stand behind their vehicles and their dealers clearly don’t like EV’s.
@TheIoniqGuy in an older video you seemed to question the AGM battery, have you come around on that? I see you have linked the one you use.
Yes, I was hesitant but someone that works in engineering at Hyundai told me that it would be fine with an AGM and I think the months of using one have proven that accurate
@ thanks for the follow up👍🏻
@ oddly, the battery you linked on Amazon says it doesn’t fit the Ioniq 5 if you use their vehicle fitment software… yet other AGM batteries of the same Group Size do. Weird.
I replaced my OEM battery with an AGM battery, will that void my warranty? If it's an issue I can put the OEM battery back in. With the OEM battery, the charge light is on a lot.
I don't see anything in KIA Connect for my 2023 EV6 yet. Hopefully I will get a notice in the mail like last time. I also have a voluntary service campaign relating to the charging port that I've been putting off. My ICCU was already replaced in June.
Still no notification, but it shows up now if I try to make a maintenance appointment -- wasn't there a minute ago.
It seems like every 6 months that I have scheduled service due with my GV60 there is yet again another recall. The upside is that Genesis still picks up my car and leaves me a loaner at my convenience so no real skin off my nose at least while I still have warranty coverage. I suspect I will be cutting the car loose at that point if they can't get their recalls under control. Last service visit I asked my service advisor about any resolution to the AC charge port overheating issue, nope, apparently Hyundai still working on it. Really its been 2 years. I kind of feel like they are tossing out questionably useful software band aids for clearly significant hardware problems and hoping it buys they more time to kick the can further down the road.
Ioniq 5 owner here. Sadly I think you’re right. They’re just giving band aids to cover up serious problems. We are in a hot country (Australia) and we can’t AC charge at full current as the car will overheat. 4kW AC charging is embarrassing.
Always something with my G70, too.. I finally said screw it and ditched Hyundai Child Labor Group, altogether. Looking at EVs, but not looking here lol
I'm getting a 2025 facelift ev6 delivered next week in Norway, is the ICCU error fixed on this version ?
I have an Ioniq5 2023 limited RWD, I have taken the vehicle into Hyundai dealership on previous recall. Do I still need to schedule another appointment to go for the same issue if it was already taken care of the first time? I mean if it's not broke don't fix it, right. I don't want to take it in and all of a sudden I have issues now.
Is the Ionic 5 Facelift with 84kw battery also affected? Or does it have updated components like the 5 N?
It's not on sale yet in the US. The cars that have been sold likley wouldn't see a recall until months of sales and anything pointing that there is an issue.
Saw the recall on my new ioniq 6 (purchased October 30, 2024). Scheduled a service time and then waited almost 4 hours for the update to be completed. I can't beleive that a software update can take almost 4 hours but the dealer said they were haveing truouble and it just takes time. With over the air updates now a regular event what a flubber f***k having to wait in a dealers crapper waiting room. If you take your car in be sure to have someone pick you up so you don't have to waist half a day.
I had to buy a portable Jump starter bc I kept getting the fail safe 12v low voltage error, after getting BOTH my I5’s towed to the dealer for them to tell me the battery was fine. Lucky I have a tire swap scheduled for tomorrow, so hoping they can take care of this quickly. Oh and the iccu on my 22 SEL failed and was replaced this year as well. Peeved but still love the car
Just had my service done and asked about said recall. Service advisor had no ideal but had patience and boom found it checked with service tech to ensure they could perform it. Boom took almost 2hrs but it was done. Never had any issues even for the first recall. Fingers crossed don’t have this. Only issue I had was the added miles to get the first recall done. It a lease and Hyundai finance doesn’t give you credit for those miles incurred 😡.
Any idea if the 2025 Ioniq 5 will likely suffer with this issue?
I thought I saw that the Ionia 5 2025 is not in the recall. Is this true ?if so is that because it is not for sale yet or was it was fixed in production??
Does anyone know if the issue is actually truly fixed? After doing both recalls my ICCU failed. I want to lemon the car at this point as I don’t trust that the issue is actually fixed even if new part is put in.
Yup my 2023 I5 is not quite 2 years old and the ICCU failed on the highway just a week after the "dead 12v battery" was replaced. Also, the dealer service person admitted that my problem with occasional errors in shifting could be due to the faulty ICCU (turn knob to R and it occasionally decides to go to D).
I had the I5 updated and fixed all recall and a week after, it didn't take charge anymore. Luckily I have 20% left to get to dealer and now I have to wait until the end of the month to get ICCU Replaced without a loaner. I'm getting tired of this car event it very smooth to drive.
Really sorry to see this repeat debacle. I was the proud owner of an Ioniq 5 until seeing the first ICCU issue, at which point I pulled the plug and went Model Y. I loathe Musk, but hate being without a car even more so.
@@vlad2838 I did the exact same thing.👍🏾
My wife wants to give up now too. Likely go back to Honda/toyota for reliability
My ICCU went wrong and the car was flat bedded. With the new ICCU there is a really irritating high pitched whine. It is loud enough that I can hear it over the radio. Haven't taken it back yet but I do hope I'm not going to be fed a load of denial bull.
My car went into Turtle mode! Before the 12v battery warning popped up. I had to get roadside assistance. Dropped off my 2022 IONIC 5. They have to replace the ICCU! I called Hyundai customer service to follow up on cost for a rental vehicle. Now I am waiting for the parts and installation. Seriously how annoying!
Wouldn’t be too bad if we had good dealers in Northern VA, but we don’t!
I called the dealer that sold me the 2024 Ioniq 5 last week and they said that they do not have a software fix and that it could take up to 30 days to receive one. I'm calling again next week.
Mine failed on my plug in Tucson. 3k into driving it
@theioniqguy my Kia EV6 passed and was addressed for ICCU update check.. pre 100K miles then at 102k miles it fails. If you can help me get this addressed and fixed thanks. Don’t pigeon whole yourself to one brand. You review cars the Ioniq 5 got you excited Best wishes 🎉
I didn't see the Ioniq 5N listed as an affected vehicle either. Unless it's considered to be an Ioniq 5 (I feel like it's often listed as a different car but maybe they just consider it a trim level).
I saw a person with a brand new EV9 at a charging spot in Canada a couple of weeks ago and they had to call roadside assistance for a dead 12v, road side brought a jumper while I was there. He told me he left the car with a low charge overnight. So I'd be surprised if the issue isn't also present on the EV9.
How long does this take? Wondering if I can wait for it to be done or if it's a drop off and pick up later kind of deal.
If it just needs a software update you can wait for it. But if they find the ICCU needs replacement that will take much longer. Unfortunately there’s no way to know until they actually run the diagnostic.
Dangit my EV6 AWD has been trouble free but now I’ll go in for preventive care 😖
Do you have the Hyundai recall pdf that would list the new ICCU version number? I need that before going into my dealer. Last time when I went in for the VCMS L2 charging fix, they claimed there was no update available and marked the campaign as completed. I had to raise hell as the software version was still the old one. They finally took me in the back and showed me on their tablet where it popped up in auto mode but supposedly the tech was trained to ignore and go into manual mode and did not see anything. Basically had to show the tech and service manager how to do the update lol.
sounds like you need a better dealer?
That is awful, I'm fearing the worst outcome and experience if this happens to me, any headway on your PDF ICCU version new # to pass that along to my own dealer
or at a minimum double-check they know what they're doing?
AGM battery installation- can this only be done by the hyundai dealership or any mechanic will be able to do it?
Dealership likely won't install anything that's not theirs. Any other shop would do it. If you bought an AGM from any auto parts store, they'll likely install it for free.
@ great. Thanks for the reply
I thought it may need some technical fix or attachment with the high voltage battery.
I am based in Australia. Recently got my ICCU fixed. Would change my 12v battery now and will be using BMS to keep an eye on 12V battery.
Hope we get the 2nd recall soon in Australia and this ICCU issue gets sorted for ever
Hi, I got my UK version Model Year 2025 (MY25) IONIQ 5 N Line S AWD last week. It’s great. With a rear windscreen wiper!
I bought a magnetic sunglasses holder and a charging port lights blocker from you on Etsy. The sunglasses holder is great, but the item to hide the lights during charging does not (a) cover the newly-designed charger lights, and (b) won’t fit anywhere when you close the charge door… it’s just not the right shape for the new design. MY25 items from your on-line shop will need to be amended/redesigned to fit. Thought you’d like to know.

I have a 2025 Ioniq 5 N. Does this recall effect my vehicle? I did not have anything listed in my bluelink app. Thank you.
No, 5 N is not recalled
@TheIoniqGuy Thank you for the quick reply! Appreciate it.
I had my ICCU replaced earlier this year after it unexpectedly went pop from the rear seat and I got as far as my 12v battery lasted. I was off the road for 6 weeks as parts were sourced. I think the clock is ticking on all of them.. I feel sooner or later they all need to be fully replaced.
I’ve had absolutely no problems with my 2022 Ioniq 5 Limited until last week. (I purchased the car in June 2020.) I was taking my wife to the hospital for surgery when I received the notice to check the car’s electrical system. The car soon went into turtle mode but I was able to get it back home and use our other car for the hospital trip. I’ve made an appointment with my Hyundai dealer for Monday to have the car fixed. Sure hope this is the last time we have to deal with this issue. Good luck to everyone and, based on my experience, I wouldn’t wait to have your cars serviced.
Update 12/5: I had the car towed to the dealer on the morning of 12/2 and was told they would diagnose the problem by the end of day. I decided not to wait and the dealer provided an Uber ride home. I received a call later saying that the ICCU unit needed to be replaced, so I arranged for another Uber ride back to the dealer and they provided a loaner car. The ICCU unit was shipped to the dealer on 12/4 and the recall was completed that afternoon. I was expecting a much longer wait for the part to arrive. Great service from CardinaleWay Hyundai in Glendora California.
Perfect, just got the older update last weekend... -_-
