Have IONIQ 5 SEL 2023. Never had any trouble with ICCU or Fuse or charging 12 volt battery.Mine was just updated by dealer.
So I’m good for now. Enjoying car!
I had a “stop vehicle and check power supply” failure light on Sunday. I immediately stopped, and since I was less than a mile from home I drove home. I had 95% power on main battery. Note that I had had the ICCU software update and inspection about a month ago nevertheless, I turn my car off. the next morning had the same issues except for the 12 V battery was completely dead and the car was undrivable. Ioniq five died in neutral and I was on a hill, so had to call a friend to come and put blocks under my wheels before I could get out of the car safely. is now been safely towed to our local dealer who has ordered the ICCU part which takes an additional three days from order time to arrive. The dealer was kind enough to lend me an ionic six because I have multiple appointments during the week. so yes, even though I had an inspection conducted and a software update at 19,000 miles of high satisfaction driving within 500 miles later the ICCU failed. I’m thinking that the software update doesn’t really prevent/protect from the mechanical breakdown of the ICCU?
Sorry to hear that! Yeah, I don't think it does. With the previous poorly functioning software, the damage was already done to the ICCU and it was just a matter of time. I think some folks will just get lucky and never experience it while others will.
I had the recall done on my 2024 Ioniq 5 Limited AWD a couple of weeks ago. They didn't find any DTC and thus didn't need to replace my ICCU, just do a new software download. I haven't noticed any differences, but perhaps (?) my guess-o-meter isn't make such wild guesses…? So far, that is. We'll see. I'm just glad that Hyundai is proactive in supporting its vehicles -and its customers.
My IONIQ 6 is currently in the shop. ICCU was dead after being parked overnight. 3x within a week's time.
I've owned my Ioniq 5 in the UK for 7 months and had the ICCU hardware and software recall completed shortly after handover. The confusing issue with the recall is the number of owners who have reported ICCU failure after the recall was completed. In a number of cases replaced ICCUs have gone on to also fail, indicating the ICCU in it's current form isn't fit to do the job it's designed to do and there's suggestion that Hyundai are completing software updates to choke back on ICCU performance to reduce heat build up. In addition to the heating issue there have been a number of ICCUs fail due to coolant leaking inside the ICCU, it's clear that the ICCU isn't fit for purpose and Hyundai are trying to mask the issue with software updates which isn't the answer.
Thanks for the update Corbin. There have been reported ICCU failures on the EV9, unfortunately. Not sure what to make of it. Would have expected the EV9 to get the bullet-proof ICCU.....
2023 IONIQ 5 Limited here. I did not have the ICCU failure, but about 2 weeks ago the 12V completely died when parked in my garage. This happened twice, and I quickly took it into the dealership to have the recall SW installed. This was done, but a week later, I have had two more events where the 12V just dies. Have another appointment with the dealership on 4/16, so we'll see. They probably did not see the DTC code, so no other fixes were done - just the SW update installed (took them 40~ minutes). More to come.
Just got mine done in Ottawa, Canada…Thanks for the background explanation.
Thanks for the additional details on the recall! Interesting info.
My 2022 Ioniq 5’s ICCU failed in February. It was replaced and software updated. Luckily - only took 3 days.
My 2022 Ioniq5 SEL failed me 70 miles away from home on a cold rainy night when it would not charge, neither DC nor AC. Hyundai roadside assist towed it to a nearby dealer the next day. They initially said something was draining the 12 volt but couldn’t find what it was. They ended up replacing my ICCU and air-conditioning compressor. It took 9 days for all that, and I asked if they replaced the 12 volt also; they said no because it tested ok…
10 days later the 12 volt died in my garage, and I had to use Hyundai roadside assist again. My local dealer spent 2 days determining the 12 volt had to be replaced!
It sucks to be an early adopter…I paid $57k for an unreliable vehicle.
It is an adventure and I only paid US$45,200 out the door and net of incentives ............'22 SEL RWD ....but the most I ever even considered paying for a car. I did expect 25 years of trouble free ish driving and low/no maint and low fuel cost. I am retired and really don't mind being a guinea pig as long as they give me I5s or equiv. for free loaner while they figure this shit out. I went solar in 2012 and absolutely no issues ever - besides free electricity and clean sunray power for my EVs.
56k miles and 26 mos. and still lovin it. I really want all fossil fuels to stop being burned and I want to lead by example. AND I kinda like being an early adopter, advocate, ambassador, spokesperson, messanger and promoter.
BTW: I would have a Model 3 from crazy pot smoking freak boy.....but he wanted close to US$15k more than $45.2 K and that was just fucking nuts. The MRS was already considering ending our 36 year partnership cause I spent all that cash on my I5.
BUT, we all need dependable cars, all the time, cause we got places to go and that is what we expect. NOT an unreliable car.
I just received my notice today (4/27/24) and have an appointment at my dealer next week. Your great reporting certainly reduces my stress level when getting these notices. Thanks for the great information.
This video and past videos on this subject illuminates perhaps 2 reasons why we have not had any issues with 12V charging and no error codes from the ICCU in the March update. We are scheduled for this next update April 25th. Or car is a 2023 Ioniq 5 SEL dual motor.
1. It is always garaged overnight and we live in a temperate climate in the PNW. Therefore our car has not experienced temperature extremes when sitting for several hours. The only time it sat over night in temps below 30 degrees F was in Rock Springs, WY on a road trip late January 2024. It that instance it was plugged into a L2 Tesla Destination charger at a hotel.
2. Except for road trips, we charge at home 100% of the time with an L2 charger set at 40 amps whenever SOC drops below 30%. The only time the car dropped below 10% SOC was on above road trip and was recharged at a EOA DC fast charger within minutes. The car has never spent any extended time below 20% SOC.
I offer this up only as a data point and in no way imply that folks need to manage their charging routines differently. Hyundai absolutely needs to address this ICCU issue so that folks can trust their cars in all normal operating conditions.
Same for us, we live outside Tacoma WA and charge at home 95% of the time and only fast charge a few times per year on trips. 47k miles and no iccu failure or any other issues yet.
Mine has never been on a fast charger, but the battery still died.
@@wjgoggin thanks for sharing that info - I was curious.
No EV here yet - but I imagine that it will be L2 home charging most of the time and DCFC when road tripping.
Another great concise information video
Thanks for the update. I'm scheduled for an update April 6th. At least I'll feel a better sense of confidence on the road. I'm good now but the update would be a plus.
My 12 v battery in my Ioniq 6 failed after 10.5 months.
Had the update and the 12v battery failed the next day.
My battery monitor showed that when I unlocked the car and pushed the start button the 12v battery discharged from over 12.5 v to 7.7v almost immediately, within seconds.
I jump started it, took it to the dealer.
They had it for 2 days, it did it for them and showed an internal short in the 12v battery.
They replaced it immediately and the car has been perfect since.
Perhaps the ICCU damaged the battery, don’t know.
Hopefully the update might fix that.
This is in Australia.
Very happy with the local dealer.
Managed to get in quickly thanks to your original video @theioniqguy - my 2024 was done in 2 hours ish. No change for me in throttle or driving that I noticed.
I have a 2023 Ioniq 6 purchased a year ago next week and my ICCU just failed. Luckily I was able to limp it back to my house and called roadside the next day and had towed to my dealer. I had an appointment set for Monday 😢 but maybe that will work in my favor and get all the parts ordered and installed quickly.
I’m fortunate enough to have other vehicles to drive in the mean time so im not without a car.
Had my update last week but had another error code about the air flaps. Of course, that error code disappeared at the dealer. It was gone for a couple of days so I thought the update had fixed it. When it return the error codes were always there. Went back to the dealer and he says my error code history was over a page long with different errors so he couldn't point out the error (too many errors?). He said to come back when it happens again. The problem is that it now happens every time I start the car. I am going on vacation, so it's not getting fixed anytime soon. I did notice that sometimes one of my air flaps doesn't open but I am not sure this causes all the other errors.
Got this update, and experienced my first 12V battery death at 90% of main battery charge while connected to an L2 charger… 🙄 After installing a 12V battery monitor, I noticed that parking my Ioniq in front of my house without locking the doors could drain the 12V battery from 100% SoC to 10% in just 2 hours… Even though I received only one notification.
The ICCU in my GV60 failed 3 weeks after I had the software updated... it happened at a very low speed, while backing out of a parking lot. Just went "pop." It seems to me that high voltage battery charging the 12v battery can also cause the ICCU to fail. I don't know how it can damage the FETs with over-voltage under this scenario...
I’m a member of a UK Ioniq 5 Facebook group, a rough and ready poll was done which reckoned the ICCU failure rate was about 10%.
wow.......1000% more than HMG thinks?????
@@ronnelson06824 The poll wasn’t very scientific.
I think also, my ICCU Unit failed yesterday, AC Charging still possible, DC Charging not....I think the failure rate is much more above 10%, I think sooner or later every ICCU Unit will fail.
Interesting, so it is possible that if you use a higher regen setting, you are more likely to overheat the ICCU. Maybe you should run a poll to see the what regen setting those that have had ICCU failure were using.
I had never ever used One Pedal driving full regen mode...........I liked 0 regen and lots of roll and then pull the regen shifter on the wheel whenever I needed to slow or stop AND I still am having these issues. I always keeps SOC to over 40% and car never sees extreme temps. 26 mos and 56k miles. I have charged my car hundreds of times @ l1 and l2 and l3 (when it was free) and always charged when I wanted to and never cared about 80% or anything for that matter. I aways thought: if they build it, allow it to charge on these diff amps/speeds......The BMS will do whatever to keep it as healthy as possible..........I DO NOT WORRY ABOUT ANY OF THE DOZENS OF BATTERIES IN MY FAMILY'S LIVES........and this battery and BMS should be the best in the house!
My local dealer completed the recall update on my 2025 Ioniq 5 Limited -- just in time too , because I am taking it to Upstate NY for the eclipse this weekend!
My (Dutch) Dealer fitted a set of all season tyres on to my 2023 Ioniq 5 in February and afterwards told me they'd also installed two SW updates; one for the electronic hand brake and the other for the ICCU.
I hope that this is the fix you're talking about but wonder if they'll still be recalling the car in the near future.
Until now I've had no battery issues, but also never leave the car standing with less than 20% SOC.
My battery monitor reports that the 12V battery is topped up at least once a day when not in use, which looks good to me.
My 2023 58kWh just did 14k km, no issue. But when the regen is one factor, an Software update can be a fix. About the 12V battery Drainage they first need to figure out why it does it...seem they did not really find the root cause yet. Hope they fiy it in the 2025...
My I5 was delivered 10th May, brand new MY24 ultimate trim. I’m in UK so checked car using government website (that’s how it works in UK) and surprise surprise… there’s a recall! How can they be selling brand new cars like this
Lease ending on my 2021 Kona EV. Love the 2024 Konas, but local dealers can't keep them in stock. OTOH, their Ioniq 5 inventory is rising, up to 61 vehicles at one dealer. I should be able to make a great deal for the Ioniq 5. They will have the new ICCU, but what about the entertainment software? Will I be stuck with the old version?
Yes, maybe the on demand Battery condition will come to the pre facelift...
Looks like maybe the 2024 Ioniq 5 will be getting the infotainment software update.
We got the first iccu update around 36k miles, now have 47k miles and never still never had a problem with ours. But I still made an appointment to get this newest update to be safe.
I just got my recall done as well. From what I noticed after the update on i-pedal the car no longer pauses for a split second after coming to a stop sign and going again. Not sure if it's a placebo effect though 😅
A few owners in the UK have had dangerous failures on fast roads at night with very little warning and total power failure ,so not even hazard lights !! So id take fail SAFE with a pinch of salt !!
Can you go to dealership for update even if your VIN says there is no recall?
Any update on the charging issue? Still cannot charge with my 50 AMP level 2 charger at home.
I'm of course concerned re the dead battery issue but after 17 mo. of ownership no issues with that. I did not get the ELE 283 update as I was concerned with throttling when charging AC or DC. So is there no mention of the ;problem with terminating the 48A AC charging? I can charge at 40A on "reduced" without it stopping (at least for now) but I've tried 46A, 43A, on max and reduced. The best it will do now is 40A reduced without stopping early. Is this a different problem or no????
I have a 24 gv60, and havent had any problems. Genesis dealer called me and said there's a recall, they scheduled a pick up and dropped off a loaner, then a day later brought my car back.
How can an software update fix the hardware issue of MOSFETs blowing up ?
I think there is some issue in the cooling system for the ICCU.
This is an update to the way the cooling system works to cool the ICCU
My 2023 Ioniq 5 went in this week for a software update and they replaced the ICCU & fuse as well. Didn't have a problem before or after. Can't say I notice anything different. I am in the UK.
FB Response to Danish regen causing ICCU to fail.
All uses regen most of time. Only one in 20 was from hilly downhill breaking.
The rest with standard urban driving.
But all 19 of 20 also has had 12 Volt issues.
Thanks from 🇩🇰 for relevant technical information.
The EV9 had an OTA update for the ICCU in February because the coolant pump wasn't turning on when charging in cold weather. Some owners before then were ending up with damaged ICCUs after just several AC charging sessions.
Brought my 2023 Ioniq 5 in for the recall. They also said that i only needed the firmware/software updated. That was on March 25. On April 1 (how ironic!) 12V battery was dead while it sat unused the previous 24 hours. Will be going back.
get recall, get TSBs, keep firmware/software updated............and this thing rears it's ugly head????? WTF?
Thank you @TheIoniqGuy. I had it done on my 2023 GV60P yesterday (Apri 4 2024). I personally never had the issue. Service rep said they had not seen a single Genesis EV with this 12V battery ICCU issue, which or course is only anecdotal and doesn't mean much as to the scope or number, but an interesting data point nonetheless. This was in Fairfield CT Genesis for reference.
another Fairfiield person!!!!!!!!!
I had the ICCU replaced last October on my '22 Ioniq5. the fuse popped, the car slowed down, the emergency messages, etc. Yesyerday my 12 volt battery died. It's at the dealership today for the latest update and the battery issue. I'm waiting for a call from the dealership. Question, is the 12 volt battery covered by warranty? The car is almost exactly two years old and has 16, 100 miles on it.
Yes, the battery was replaced under warranty.
Mine took more than three hours! (software only, no parts replaced) Maybe they parked the car for a while first?
I took car to dealership of 10 times and nobody fixes my ICCU and still does not charge properly at home they don’t care
I just checked but my VIN says there is no recall
I have a 2022 ev6 and my vin shows no recalls. 🤔
Just got mine done this week in Ottawa Canada
Thanks for the info!
Hyundai ~ “Vehicle started normally to be pulled in. Ran on board battery test, got D00 good battery result. Checked non-sleep controller detection, no stored data. Went to pull vehicle out and it prompted to push start/stop button with key fob, after doing so cluster gave 12V battery low warning. Ran on board battery check with message displayed on cluster and got another pass result. Tested battery with GR8 and found battery at 7.54V. Battery likely has intermittent short condition. Replaced 12V battery, vehicle now operating normally.” If you want me to email you the service record I can. This was before the recall. So a battery can be at 7.54V, pass the diagnostic test and not log the low voltage issue even though the dash is displaying the fault. How can it accurately charge it if it isn’t seen as a diagnostic issue or logged as a fault. I only hope the recall fixed the logic that has a major flaw.
You mean that ICCU problem is happened when
1. Low SOC
2. Regen braking
3. Loss of traction
?
It happened to me in Sweden
My 2023 GV60 stopped charging on 2/23/2024. More accurately it would charge for about a minute and then stop. I took it into the dealer on Monday, 2/26, since all Genesis service techs had left Meriden Hyundai/Genesis by the time I discovered the problem late Friday afternoon and they don't work Saturdays.
Since it is a Genesis, they have provided me with a loaner G70. It is still not fixed and I have no definite date when it will be fixed. I discovered it because I started getting a warning on the car's screen: "A possible condition with your Battery Management System has been detected. A full system check is recommended to be done when convenient. Please contact your local dealership to schedule an appointment." I noticed it would stop charging shortly after the charger was connected. They have not given me any information about what the problem is, but have said they are replacing the main battery. Last week they told me the new battery has arrived after more than 4 weeks, but they're not sure when it will be installed.
wonderful content You rock @IoniqGuy
its like that for everything and it is vocal minority the ones that have the problem are the ones talking about it.
I have an I5 along with my parents. Neither of our ICCUs have completely failed, but we have both had nagging dead 12v battery issues, like many others. This has lead to bring stranded with kids and extra trips to the dealer who refuses to replace the 12v battery because, according to their tests, nothing is wrong with the battery.
As far as I can tell, no one really knows why these 12v batteries continue to die. Hyundai seems be blaming accessories and 3rd party apps, but this is BS. It surely must be related to the larger issue with the ICCU, no?
Thank you for your coverage on this important topic.
Connect a £20 bluetooth monitor to the 12v, battery, will plot over time when car is / or not ,charging it .
My 2023 ioniq 5 completely died. I had to get it towed to the dealership and it’s been there for a week and a half. Had to get a rental car which they don’t cover. Pretty crappy. Thanks for letting me vent! 😖😵💫🚙💀
When the alerts came on for me, my car was at 71% charge, I was driving 5 min locally at like 35 MPH. On the 5 min drive home, the car wouldn’t go over 20 MPH. The next day when I tried to start it for the tow it was totally dead. So glad I was just driving close by my house and not on a highway!
but will this actually change anything? people on reddit are saying they still experience the issue even after getting the update to SW...
Like I mentioned if you already have an ICCU with major heat damage, it might not take much to push it over the edge so I’m sure it’s still possible for it to fail at some point
We just bought a 2024 Ioniq 5 and dealerships are doing the software update before you leave here. It's against the law to sell the vehicle until this recall software update. Our Ioniq 5 stopped charging after the update and the ICCU needed to be replaced by the dealership. We waited 1 and a half weeks after purchase to get our car.
Hyundai better get their act together, this is crazy and completely unacceptable.
Glad I got mine updated at only about 6 weeks into ownership. Maybe my 12V battery has a shot at a somewhat normal service life.
I am not noticing the light on the dash for 12V system charging nearly as much. My garage is detached, so I have a direct line of sight to the car right from my kitchen. Before the update, I saw it charging most days, I’d say. Since the update, I haven’t seen the light at all.
The scary part for me, at the moment, is that I didn’t get the physical blade keys at delivery of the vehicle. Still waiting for them to arrive at the dealer. If I had a 12V issue and needed to jump the car, I’m SOL!
Are you driving an Ioniq 6?
@@TheIoniqGuy Sorry, yes, an Ioniq 6.
The new key fob design is truly stupid. Why would you remove the ability to store the key in it like with all previous Hyundais? I heard somebody saying that their dealer lost the keys for their car before buying it and then his 12V died and he literally had no way to get into his car.
@@TheIoniqGuy That fob is the worst. So cheap and lightweight, too. Works fine, but to me, the smaller and more squarely shaped, the better. They could’ve done something cool with the “H” in Morse code instead of shaping it like their logo.
So whether you choose to add a ‘25 Ioniq 5, Ioniq 6, or Kona to your fleet, you get to live with the fob, too. Enjoy!
Brought my 2024 Ioniq 5 in for this recall on March 27th and they found another recall apparently.
GENERAL 30D167 HCE24-91-P190. P210 SERVICE CAMPAIGN Y 1 NE TMK SEALANT LEAK CHECK AND TMK KIT REPLACEMENT
Part 09131 N1001 QQH
Apparently there is a potential coolant leak and the gasket needs to be replaced.
Have you heard of this one?
That’s the tire inflation kit not car coolant. Good to know there is finally a TSB for that though
Ah okay, thank you, I must have heard them wrong.
Since we in the USA get OTA updates, any known reason why Hyundai doesn't just push out this update for the ICCU? Seems like that would much more cost and time effective for Hyundai, dealerships, and owners!
Because part if the recall is to check for error codes in the ICCU to see if it need to be replaced. That step cannot be done over the air. It is not just a software update.
Hyundai Europe says that the Ioniq 5 only supports infotainment and map updates via OTA. It needs to go in to the dealer for system SW updates.
The Ioniq 6 supports OTA system updates and the 2025 Ioniq 5 too, according to reports.
Ioniq guy will you very address the issue with the backup camera on the Ioniq 6. At night in a dark area when you step on the brake in reverse the brake lights wash out the camera optics. Come on you have 1000s of followers who need to know.
Now they need to fix the poor battery protection plate! Thats my biggest concern.
Tell me more about that. I wondered how well the battery is protected. Are you talking about the underside of the car over the HV battery? I understand some cooling lines run between the battery and that plate.
There have been at least 2 cases in Canada where very minor damage was done to the protection plate and they couldn’t be sure the battery wasn’t compromised. Hyundai said the warranty was void and they went through insurance. The cars were written off. $60,000 +. I’ll look up the RUclips clip and let you know which to watch. Ionic Guy did a short talk about it in response.
Look up “Motormouth: $60,000 to replace battery”
I had an update and it didn’t help. I’m assuming I had enough damage occur to my iccu that it was bound to fail. Anyway, I got it replaced.
How long did it take and could they do it immediately?
About 2 weeks for the parts and half a day to repair. Car just sat at the dealership.
Same here.. I was quoted 2 weeks before they would even look at it if I had it towed there, and 2 months if I scheduled maintenance! I had to get a rental… nearing 2 weeks now. Did you get a rental? If so any luck w the dealership reimbursing? I’m going to ask but doubtful. It’s ridiculous…
No rental needed for me. Some dealerships offer loaners, no?
Am I right to think all those times (after failed ICCU to get off the road) you mentioned are with a Healthy 12V at >95% SOC which is not realistic for lots of us with that poor quality OEM 12 V batt. imo
Unknown but that’s a very good point
Thank you everyone who reported these issues to NHTSA!
hyundai and kia need to spend money on repairing and recycling batteries like other car brands. every recalled battery that goes into this crap boxes ends up in the ground
No, they 100% don’t
Roughly speaking, this problem seems to be caused by a low-quality charger. People who know a lot about computers and smartphones never use cheap chargers. Because I know how serious the problem will be.
Many chargers on the market are made of cheap Chinese parts. Remember how many chargers at electric vehicle charging stations are broken. All such low-quality chargers must be removed. Cheap, low-quality parts made in China should not be used.
I beleive that the issue with (say) EA is not the parts but the design.
They need to support so many different types of vehicles at different speeds over (once again as an example) Tesla which has (until recently) only had 2-3 levels of charging supported and nothing as low as 50.
The interior design of the EA cabinet is so much more complicated than the Tesla. Payment verification is part of it but trying to interrogate the vehicle to see what speed/capacity the battery can take is a huge hurdle to jump.
EV6 here. 45.000km. Just had my ICCU replaced. Always auto-gen mode and Rolling as far as possible. 12V battery never reported under 79%.
Blew during 11kW AC charging at home. Car could drive for 15+ minutes @ max 40km/h before 12V battery was too low and shut down.
