I blame Government Regulators for this & other problems ridiculous emissions standards have created. People need to learn the truth about the agenda that's destroying the automotive industry & trying to force people into EVs. In school they teach photosynthesis & the laws of photosynthesis contradict the claims of the C02 alarmist. Yes it's a good idea to capture carbon monoxide but carbon dioxide is a life sustaining element on the periodic table & more C02 means more Green. A catalytic converter is all you really need & fuel injection really helps your engine run more efficient but you'll never reach the mpg standards Federal Bureaucracies have set & they set these standards knowing it will be impossible. If they really want better mpg they should promote diesel engines. What this is really all about is promoting an Agenda that's become a faith based Religion. Government needs to hand the Automotive Industry back over to the Free Market. I know some people try to avoid politics but it's impossible to do when talking about vehicles in America. 1 crazy thing is not all States in America have Emissions Regulations but car manufactures have to build cars that can sell in all States & its an example of how a few Big Government States can ruin an Industry for all States.
I agree but the blame lies in our government. These CAFE standards to improve gas mileage have gone too far and force the manufacturers to cut corners.
2021 Subaru Outback here. just had car 60k serviced two weeks ago. one week ago CEL. we didn't buy the extended warranty. so we are now out of warranty 5yr/60k powertrain factory warranty...we are as of this writing, in a loaner car from the dealer, and I got a text earlier the CEL was the coolant bypass issue, and that Subaru is extending the warranty of this particular component and WILL be fixed under warranty. I was very glad, because as a 10yr Subaru owner, i was actually considering another brand in the future. But Subaru did me right on this.
After this Subaru Forester I am going back to Toyota . I will not be looking back. My decades of Toyotas proved trouble free. I have no interest I. These crappy cars.
One more time….have you seen the recent recalls on multiple years of Toyota Tundras for frame and engine failures? Lexus LX too? There’s no perfection anywhere.
Just went on my wife's 2019 forester. I went in fully expecting to pay $1300, but it happened to be THE day that Subaru finally decided to cover them. Walked out paying nothing.
I have a 2020 forester, so far very happy with it. But I did receive my letter the other day telling me that TCV was covered till 15 years or 150,000 miles, whichever comes first. I only have about 22,000 miles on it now. I am planning on purchasing the 25-26 forester in the near future. That was my plan all along. 😊
I'm in Canada, I have a 2020 Subaru Outback Limited I bought used a year ago. Today I received a letter from Subaru Canada informing me that they are extending the warranty period to 15 years for owners of Subaru's with the TCV. Anyone who has paid out of pocket for the repair can now apply for reimbursement. Thanks for the great explanation you gave on the TCV, so far mine is holding out.
So instead of a $1200 metal TCV, Subaru replaced it a plastic one that is 1/3 the cost. Driving down the cost to make a vehicle. Then they're betting the plastic part will last 15 years, but they will warranty it during this time. By that time, perhaps the failure rate of the metal TCV will match, Given that, I think it's a wash
I just visited my local Subaru dealership, they diagnosed this exact issue within 30 minutes and within 3.5 hours they had replaced the TCV with the updated designed component at zero cost to me. If your Subaru is throwing the codes listed below, RUN do not walk to your nearest dealer. My cars oil temp was running on average 144 degrees prior the repair and had ASS fuel economy. THAT IS NOT GOOD. Low oil temps = condensation in the engine (i.e WATER) P2682 P26A5 P26A3 Model for reference: MY2021 Subaru Outback Limited 2.5
A very good friend of mine had a 1973 Subaru D/L in high school. He finally started to use aluminum beer cans to keep the cylinder-head gaskets from leaking until it finally overheated and died. As far as that plastic valve, plastic can only go through so many heating and cooling cycles until it cracks. I know. I have a 1996 Mercury Grand Marquis with the plastic intake manifold. (IIRC 1996 was the first year.) In 500,000 miles, I have replaced 3 of them. I think that led to a class action lawsuit. GREAT VIDEO!
@@electroevolution5777 The early 80's Subaru's were the cats pajamas. Dual range transfer cases, with FWD / 4HI and 4LO, adjustable suspension, If they built them like that now, I'd buy one.
@@jamesgeorge4874 I totally agree. On a side note, my last name is george and my grandfathers name is James George. Never seen someone else with the same name haha.
Subaru senior master here. Been replacing these since 2019 when they were introduced and started failing and have yet to see one come back. The redesign and reprogram seem the fix the issue. Not sure there’s much to worry about with this being an on going issue or a problem that needs to be “bandaged”. I encourage everyone to get their information from the dealer/subaru.
The dealers are full of crap, tried to sell me $2000 worth of unrelated crap then tell me half my electronics were also bad . I only let them do the TCV replacement and magically all my other stuff they said was bad was working properly again. I don’t trust the dealer anymore especially since after they did the work and I came to pick up my car I looked it over and found multiple things they didn’t do, left the main intake vacuum hose disconnected, didn’t replace the clip that holds the plastic part of intake still, other random bs.
Thanks for this. I had this happen on my 2020 Outback at 24,000 miles in 2022. I just got my letter last week . My dealership was awesome, gave me a loaner and had the fix done in about a week . I just hope I received the “improved TCV” . I may have to revisit my automobile choices . I was part of the 2001-2004 Honda Odyssey transmission failures , three replacements on my 2001. Of course I also had a 2004 Forester with the faulty head gaskets . In this case , I should have bought the XT. Next time .
Exactly. If you want to know what not to buy, check my driveway over the years 😂. I’m dating myself but add a 1979 Pinto, a 1980 Plymouth Volare and an 1986 Oldsmobile Calais. Now you know why I switched to Honda and Subaru.
My wife and I have owned may Subarus because of where we live, Sierra Nevada mountains. Our 9th Subaru , 2023 Forester, experienced TCV problems within one month of taking delivery. It was replaced by a dealer and subsequently experienced coolant leaks with in a month. Took it to another dealer and had the leak fixed. I look at the parts list from the replacement work and noticed items like manifold gasket kit. That was not a quick job to fix. I am disappointed with Subaru making the simple difficult, replace a thermostat with a complex TCV. And then designing and building, I hate to say a substandard TCV. They did not learn from the head gasket fiasco. This in the long run will be an expensive fix let alone a customer nightmare.
They've learned from this mistake, as they have removed it on the 2025 models. All car makers go through this process of research and development, coupled with fuel economy, reduced emissions, cost savings and increased profit margins.
It's only 80-90 degrees C under most circumstances. An electric kettle deals with hotter liquid (100 degrees C) and is probably made of plastic. Properly engineered design would not have a problem.
Hey, at least they provided the extended warranty on the part. Lots of companies wouldn't do that. Thank you so much for this info because I have two Subarus with these engines. One has 62k miles and the other has 44k miles, no problems...yet. Again, thank you!
Lol becuse they would have been out legal fees and then still forced to fix it. This was a decision made 100% by accounting they don't give af about anyone but shareholders
Here is the information I found on this there is a law suit. The 85-page Subaru lawsuit says the thermo control valve defect affects 2019-2021 Crosstrek, Forester, Legacy and Outback models (the class vehicles) and can manifest without warning, rendering the vehicles “unsuitable for their intended purpose.” The case alleges the automaker has known of the problem since at least 2021, when it updated the design of the thermo control valves in the wake of numerous failures and a bevy of consumer complaints.
I would wait until the new 25 come out because they have them changed in the 2.5 . I have a limited 21 with the 2.5 I'm just going to hope for the best. @@PonderingPyramids
@@HalfBit360 Better is subjective. I just happen to prefer my STI over a WRX. No big whoop. Both versions, WRX and STI don't have this issue. You do you.
Pretty common we replace these at the dealer often ive seen these fail due to it sharing wiring grounds ect with tgv’s it can cause a stall condition has caused a few people to be stranded
I've got two of them (2018 Premium and a 2018 Limited) because I wanted the next generation (at the time) while it was fresh. You left out that a 6 speed manual was available back then. Times have changed quickly.
I’ve lost count how many thermo control valves I’ve replaced since starting as a tech 😂. I’m not complaining since I get the job done quick, It usually takes me 1 1/2 hours to replace the tcv & bleed the cooling system. The common ones are the Foresters. The Outback/Legacy & Crosstrek I rarely get.
Yes I am a technician at Subaru. The TCV is located on the left hand side of the engine. Unfortunately no it won’t let you know when it goes out until the check engine light comes on with all the other lights. Most common symptoms are no heat and reduced engine power. As a fail safe the radiator cooling fans stay on at the highest speed to keep the engine coolant temperature as low as possible. Other symptoms which are rare include the car not starting or stuck in limp mode. In rare cases the thermo control valve can completely short out and since it’s in a can-line circuit with other 5V circuits I believe and also share the same ground (tumble generator valves, fuel pump pressure sensor, throttle body, etc.) and can also screw with the engine control module causing it to kinda glitch but it won’t cause damage to the ECM itself that I know of. In this situation the vehicle would have to be towed to the dealer for diagnosis & repair. If you are able to, what I’ve done to diagnose this problem and make the short go away when it won’t start is unplug the thermo control valve to eliminate the short. Looking from the front of the vehicle, It’s a little difficult to get at but there’s a grey connector in the back for the TCV close to the throttle body. The vehicle should start up but it sometimes this won’t always work since the ECM is stuck in limp mode. At that point again, it would need to be towed.
Can you figure out WHY the Foresters so much for failed TCV's? I thought the engines were identical when you opened the hood of a 2024 Outback vs the Forester 2.5L.
Remember that the Foresters are built in Japan and the Legacy and Outback is built in the US and possibly different lots of parts or even different manufacturers of the parts.
This happened to my (former) 2020 Subaru Outback at around 45,000 miles. I was on a long road trip and couldn’t get it in right away. Fortunately, the valve defaulted to open, so I was able to get home for service. It was a long drive without some of the features, and lots of dash lights came on. Neither the oil nor the coolant got to normal operating temperature. I know folks might not find this rational, but I was so frustrated and disappointed that I traded it in for a Honda. I still have a 2016 Outback and a 2011 Forester, but since I do so much long-distance driving, I lost trust in the vehicle. Fortunately, Subaru did step up and replace the part at no cost, but I couldn’t regain the confidence in the Outback.
@@bryandepoy8030New Pilot has really good driving dynamics, V6 engine, and probably the best AWD torque vectoring system among all mainstream SUVs! I just wish it had a nicer interior and full power passenger seat with lumbar adjustment. Even the Elite trim doesn’t have that.
My wife's 2020 failed as did her niece's. Probably an emissions related "improvement" which actually worked because engines that can't run don't pollute.
Keeping my 2017 Crosstrek as long as possible (100k miles so far)......I think Mr Subaru's Crosstrek has about 200k miles so far, original CVT (& he tows also)👍
Thanks for the info Mr. Subaru. 🫡Looking forward to learning how to DIY fix. I have a 21MY Forester. The valve went out at about 30k miles. covered under warranty but sucks to know it most likely will happen again 😕.
I know the Forester 2025 is redesign and like Mr Subaru said,they changed the TCV .But the outback 2025 model doesn't seem to be redesign.Do you know if the TCV on Outback 2025 is going to be change?
What is designed to meet EPA & bogus CAFE standards, ends up causing more pollution and fuel use with towing, parts distribution, and testing the vehicle after the replacement is installed. Then the trips to and from the repair facility. All makes sense, right????
Bought a lower trim model Outback (Premium) specifically to get less problems (no turbo to fail and less nanny features). Funny how sometimes all a company has to do is nothing and they can't seem to pull it off. I totally get that all mechanical components can fail, but this seems to be overengineering at it's worst. Thanks Mr. Subaru, you are my go-to guy!!
I just graduated college and decided it was time to finally get my first car. I was shopping for a Subaru Crosstrek and ended up getting a Subaru Outback instead. I was excited because i got it for a decent price used of course because i have money saved but I'm trying to get to grad school. It has only 56,000 miles on it and is a 2020 no less! I was skeptical about the eyesight system and scared any problems with it would be catastrophic in terms of repairs and calibration. I did my research and felt pretty safe seeing as the head gasket issue has been addressed (relatively, still not a fan of the silicon gasket). But after having it for a week the battery died. I don't blame Subaru for that, it was the dead of winter in January and the car had been sitting for a month or two before i got a hold of it. Then comes just last month. I have only put about 1.5k miles on the car so far and my check engine light comes on after driving for only an hour straight and i loose the eyesight and x-mode feature. I pull out my OBD scanner and sure enough it was the Thermocontrol Bypass Valve. No warranty, completely out of pocket I'm going to have to find a way to fix this. Luckily it stuck open and im just stuck running cold. I've loved the car thus far but idk if im starting to really regret my decision or not yet. Im trying to get settled and start working multiple jobs and get a new apartment so i can make money to get to grad school but im wishing i just bought an older model toyota with less cheap and modernized electronic bells and whistles at this point.
If you run it cold for too long it can lead to sludgy oil because the moisture never boils out and you don't want that. Change the oil frequently until you can get it fixed.
@@MyBacktrail Just did an oil change before the light came on. Used royal purple too so thought it'd do me good considering it's a little higher end than what I usually get. So much for that, but thanks for the tip 👍
@@RodneyW This is my first time buying a car so forgive my ignorance, but this is a second owned car that came with no warranty to me at least. Would the warranty not be applicable to me due to the fact that I've never bought this from the dealership it originally came from? Or is the service bulletin claiming that this extends to any 2019-2021 Subaru with TCV repair reimbursement out of pocket?
@@trevorpogue4484 Normally (I am in Australia), the manufacturers warranty applies to the vehicle, not to the owner. Thus the cover has transferred to you, as long as you are the registered owner of the car.
Love that I'm at work, watching RUclips videos as I go and happen to see this as I'm doing a Thermo control valve on a Forester. With new ECM update and new part, they seem to be good. Time will tell
The new part has to be better, but not the fix...because for 2025, they went back to the old tried and true. No more TCV for their normally aspirated engines. hmm
My CEL came on 2 days ago. Brought it in yesterday and they fixed it. Covered under extension for this part which is now covered 15 years/150,000 miles.
Another awesome video. I had this happen to my 2021 CrossTrek Sport about a month ago. Freaked me out especially when the eyesight went out. I’m past the warranty thresholds so the worry about cost was real. Dealership replaced under the extended warranty and they said they had seen and replaced a ton of these recently. The dealership also told me without Subaru’s extended warranty it would have cost me around $1800 (part, labor, taxes, etc)!!
Just wanted to hop on here and say thank you! I had a check engine light for about a week. Have followed you for a while and you post this video. I had no idea if it failed in an open or closed state so I took it right over. Sure enough, the engine codes were about the TCV and they replaced it under warranty with the upgraded part. Appreciate you and what you do!
"Don't be stressed out". Sure. Glad my failed and was fixed. Happened at home near a dealer. What happens if it goes bad on vacation far from a dealer? This issue is always on one's mind until it fails. That's not a good way to enjoy your Subaru.
I just bought an Outback Touring XT. I guess I don't have to worry about that failing now, just the turbo. Haha My wife has a 2017 Nissan rogue and we were looking to trade that in for a Forester, we just weren't sure if we were going to do a 2024 or a 2025. I guess going with the 2025 will lessen the chance since it no longer has that part.
Polycarbonate plastics really don't like many types of chemicals. The polycarbonate "windows" in modern computerized lathe housings become brittle over time because the coolant splashing on them during the cutting of metal. This can be really dangerous if a part flies out of the machine. So It's just a matter of time before they crack. I mean it's inevitable!
Thanks MrSubaru1387, This just happened to our 2019 forester after a long day of driving in 90+* weather. Eyesite warning and shutdown 15 miles from home after lettings it cool down ( temp gauge was normal ) was able to drive home most of the way before doing it again, I found that if I didn't get over 1500 rpm I could maintain 39-mph got home 5 miles found your video and your description is was exactly what was happening. Had it taken to the dealer and was told that the TCV had failed and was under warranty NO CHARGE! (Tow Bill : 365.00)
Thanks for the heads up, my 2015 Outback (150000 miles) with port injection seems to be worth putting money into rather than buying a new direct injection Subie with that TCV. Also I much prefer physical buttons for the controls instead of everything behind a buggy info screen.
When I was a VW tech , around twenty years ago they introduced the limited production W-8 engine. It too was equipped with an "electronic" t-stat with a very high failure rate. I performed several repairs regarding this component, typically caused by the engine not reaching full operating temperature as you described in the video, along with the requisite trouble codes. Coolant leakage was not an issue on this problem.
My 2020 Legacy was at a Subaru dealership for TWO MONTHS for a CVT issue (valve body ended up being replaced) which was resolved last week. Needless to say, it was an ordeal. I went to work this morning and every light on my dashboard went off like someone had missile lock on me so I drove it straight back to the dealership assuming it was related. "Here we go again..." Turns out, it was this issue and everything is totally covered! They had it diagnosed by 8:45 this same morning and I should have it back before the day is over. Some good news for a change! Great video, btw :)
Never seen a single redesigned TCV fail. Also never seen these things fail "closed". 100% of the failures I have seen led the TCV to remain open. Once an issue happens the fail safe will open the TCV fully. Also this isn't a "New Big Issue! omg!". It's been known for a long time. They have had a redesigned part since February of 2022. They finally got off their rears and extended their warranty but these things don't get stuck closed and if it does, there is plenty of warning before the vehicle over heats. Don't ignore check engine lights.
@@melissasmess2773 Not saying it ever was a good idea. But all good idea's started with a ton of bad ones. They are trying to do everything possible to squeeze more fuel mileage out of these boxers. Thermal management is one more way to gain if done correctly. This day and age, old school mechanical management isn't as accurate and quick to respond than electrically controlled.
Thanks for this video - this issue stranded me in a busy road last week (2020 Outback Limited), my regular mechanic looked at it for a few days and told me it needed to go to the dealership because it was probably a computer issue, but that it would be safe to drive there. It was not, had to get it towed the rest of the way, but thankfully it's all under warranty. This is a great video because now I can actually understand what happened
Thanks for heads up on this TCV issue. I'd rather not gamble with the lives of my family. So, it's a hard pass on the Subaru brand. I really liked everything it offered. Too bad the company won't actually fix the problem by going back to what has been a reliable part, and easy to change.
I have a 2019 Forester. My TCV went out at 115,543 miles. I guess it was stuck open as it was not overheating. Eye sight disabled, cruise disabled, chech engine light flashing and greaty decreased MPG. Codes present B2806, P26A3 and P26A5. No waiting on parts but it was fixed at the local dealer for a total of $1602. I just recently filled out the reimbursement paperwork and submitted it. Waiting to see. It seems like every year/ model car has some type of problem. My rear sway bars fell off at 600 miles, both front CV axles replaced at 100,000 miles and keeping the battery charged has been a pain.
My $.02: if you are still running the Subaru factory Panasonic battery, get something else. They suck. I’ve been running either Duracell (really!) or X2 in all my cars, work great.
I think your Forester is part of the battery draining class action lawsuit, correct me if I’m wrong. Maybe it was just a service bulletin. Regardless, several model years of Foresters, Outback, Legacy, (maybe Ascent), and Crosstrek, around years 2017 to 2022, has had batteries that die really early.
I've got a 2020 Forester.. It needed the TCV replaced last year. Now I'm hearing a creaking sound at low speeds, especially when I'm turning. I'm guessing it's a CV joint somewhere.. Can't tell if it's coming from the front or the rear.. I've been thinking about replacing it with something new within the next year.. Might just have to do it earlier, rather than later.
As you stated they all have issue! I have 18 outback with exceptions of the radio so far so good. Which is why I watch your videos To learn up coming issue! Thanks
mine just failed not too long ago, and it failed open for bypass. i was under warranty. after dropping my car off and got home i just got the letter in the mail for an extended warranty
I would buy a Subaru if I lived near this guy--great traction and fun to drive--but I just don't have a go to mechanic like this with a real passion and knowledge for the vehicles.
I have a 2015 Outback Limited 3.6, currently just turned 99,000 km (Canada). Purchased new, it hasn't given me a single issue, I follow all the recommended services.....and some, approximately 5,000 km between oil changes. My wife is thinking about a new Outback, I'm reluctant, this Subaru has been great!
This happened to my 2020 Legacy last summer. Scared the crap out of me seeing all those warning lights and the engine just died. My dealer did the repair under warranty, and apparently in my case, it also blew up the engine wiring harness which also needed replacement under warranty. The loaner car was nice, but it was a two week process. I wonder if the extended warranty also covers the replacement components. Thanks Mr Subaru!
Well snot balls! Just got a 1 owner 2019 forester with 6900 miles from the dealership, got the letter in the mail last week. Time will tell. Thanks Mr Subaru for the diagnostic tips, great information.
Almost 90K on my 2019 Forester purchased new - knock on wood, but no issues with it so far. It's been a really good car so far. The infotainment used to mess up sometimes but I think a recent software update fixed it.
I bet some of it comes down to how easy it is to make one outta recycled materials. They're committed to the net-zero waste stuff. Absolute guess, and I don't know anything about anything.
A big thank you to Mr. Subaru for this video. I watched this video about a month ago and verified that both my wife's 2021 Outback and son's 2021 Forester have this part. I downloaded the service bulletin and gave my dealer a call. The told us we would have to wait till it failed before it would be replaced. They said we could contact Subaru Customer Service but that would not do us any good. Well today 9/1/2024 the unit failed, thankfully it failed open and we were able to drive 25 miles back to the house. Had I not seen this video I really would not have know what was going on. My wife's Outback only has 26000 miles on it since we are retired and do a lot less traveling. The car is her baby, garage kept and well serviced. Two months ago the OEM battery died of course out of warranty. Subaru did give us a voucher for $250 after I complained. This is our 3 Outback, we have owned two 2015 models and I still have my 2015. They have had some issues but nothing like this. While I am sure the car is still safe to drive it sure is not instilling much comfort for any long trips. At the very least they should be notifying those owners with this issue by mail .
@MrSubaru1387 Thank you. There is a disconnect between my brain & fingers... that's what I meant to convey. You are my go-to Suby advisor. Thank you, and 2 thumbs up for your channel, sir! 👍👍
Mine just failed 3 weeks ago. 2019 Forester. 95,000 miles. Dealer warrantied under the new 15/150,000 warranty. One day repair. Only issue so far with this vehicle.
I'm glad you did this video because last night my wife's 2020 Forrester started doing crazy things, i watched this video and it answered all my questions, my TCV is bad and luckily it failed open. Thank you!!
The old coolant crossover pipe was the first and biggest failure on my '05 WRX STi. Warranty repair thankfully, but still hurt to see the engine pulled out of my new car at only 4000 miles. Glad I gave Subaru a 17 year break to see they made it worse. Hopefully the '23 FB25 revised part isn't failing as much as the '19-'21.
You would think that Subaru would spend a little more time testing their stuff before having "issues" and having to go through multiple revisions to get it right. This seems to happen with everything Subaru comes out with. Like get it together R&D department!
Bought my 2020 Forester certified used last June (2023). Got the letter from Subaru about extending the TCV warranty first week of May, and then of course a few days later (5/10/24), it failed driving home from work. Luckily I had just left and was able to pull over into a parking lot right away. Dash lit up like a Christmas tree, car wouldn't go over 10 MPH, and engine revving up and down non-stop. Dealer confirmed that the TCV failed, and also found a faulty intake manifold. Both replaced under warranty at no cost to me. When I got it back, the car ran great, although it seemed to run a bit rough when starting cold, and smoothed out when warmed up. Had the car back for 14 days, and again, leaving work had the same issue, minus the engine revving high and low. Dealer says there was some carbon buildup, and they are doing a "deep decarbonization" of the engine, and also caught a misfire on cylinder 3. Not sure if these are related to the TCV, but the car ran absolutely perfect until the TCV failed. Hopefully I'll get it back in the next day or so...yikes.
Just happened to my '21 Forester at 59K miles. Got the typical symptoms of all warning lights coming on and driver assistance systems being disabled. Took it to the dealer this morning and all is good and no cost to me. Got a nice Outback loaner for over the weekend while they do the repair. Good job to Jim Keras Subaru on Hacks Cross Road in Memphis. Hey, shit happens and cars break. At least Subaru is covering the cost and doing the right thing.
Well damn. My wife has a 2022 Crosstrek, and the winter of '22-'23, for about 3 weeks in the Alaska winter, the engine would not warm up, stayed cool with no cabin heat. I figured the thermostat was stuck open so I got an appointment with the dealer....4 weeks out. In the meantime it started working correctly and worked fine last winter. Keep an eye on it?
I suggest reporting it so your shop can log it into the records. If it ultimately fails after warranty, it can be traced to starting to fail when first logged, hopefully within the warranty period.
I have a 2024 Crosstrek Limited with the 2.5. I immediately noticed that on cold days, it struggles to warm up and stay warm. I figured maybe a bad thermostat, but that’s extremely rare on a new car. Now I know why….
The new 21319AA040 valve part only cost 288 online. The one time use gas line is 54. New gaskets about 6 bucks total. Add in some subaru coolant and the total for me came to 399. While my 2020 subaru forester has no issues yet I would rather swap this in now because realistically you could end up spending 200 for a tow to the dealership plus the down time of not having a car. Add in the fact that if this happens on vacation you could find yourself having to cancel or extend plans. 400 bucks to keep that from happening is worth it to me. Ymmv.
Not only is it going to be hanging over our heads, but after 15 years, they won't have to even keep parts. I find it hard to believe that with modern prototype testing that they didn't already know that there were going to be problems. How else could they come out with a "fix" so soon?
We bought a 2020 3 weeks ago, it took 3 days before we got a P26A3. Fortunately it's at only 112k. Scheduling the repair at the dealership this week, very glad to have found that warranty extension before paying out of pocket at our local. Hopefully the replaced TCV holds up until there's a retrofit kit to put the 2025 crossover pipe on and a DIY ECU flash to go with it!
so now i have to worry on my next road trip. need to pressure sba to recall instead. once consumer reports gets on this there goes their reliability ratings. I wish mine would fail already to get the new part. My dealer said they won’t preemptively replace unless it throws codes
My ‘23 Forester Premium has steadily been losing coolant.. I have to check it closer. Edit: I just remember, the safety systems on my car were shutting off randomly right after turning on the car and started driving, then the CELs would turn off on their own (this has happened 3-4 times in 6k miles)..makes me wonder now if it’s the TCV failing.. 🤔
Wow. My daughter and I were considering an Outback or Forester. Previously have had several Volvos since 1989 which all were very reliable, and survived accidents. Now too expensive, so looking at Suburu. Thanks for video and explanation. I’ll be holding on to current 2011 Acura RDX until it’s done.
First coolant service is what 10 years/100,000 miles? I don't think maintenance will help these TCVs last longer on Subarus that have them. Unless maintenance means "replace the TCV before it breaks" which seems like getting into German car thinking, lol.
Once I started seeing the problems around RUclips and seeing with my own eyes the electrical gremlins on my top of the line Legacy, I decided to switch to an Alfa after 2 years despite I purchased the longest warranty and I could never be any happier! In 2 years of Subaru I had to go twice a year for services plus other 3 times to fix electric problems in the car that were not solved because after re-using the car, after having the whole system restarted, it would still give me the same problems. In other words I went 4..5 times a year to the dealership, a real pain. With my Alfa I have to go only once a year and it has been way more reliable and capable vehicle than Subaru under every single aspect.
Good information. Wife was considering getting a 2022 Ascent to replace her 2014 Forester with 281,775 miles and the front oil leak. Something to think about as well as fixing our oil leak / reseal. If you're interested in fixing our leaks, we can drive the car down from Virginia and drop it off.
You would think cars have been mass produced for over 100 years that they could build a car that should be truly reliable by now.. I for one am getting sick of this shit. For one thing this part should be full replacement for the life of the car not the owner it was and is there f...k up.

I blame Government Regulators for this & other problems ridiculous emissions standards have created. People need to learn the truth about the agenda that's destroying the automotive industry & trying to force people into EVs. In school they teach photosynthesis & the laws of photosynthesis contradict the claims of the C02 alarmist. Yes it's a good idea to capture carbon monoxide but carbon dioxide is a life sustaining element on the periodic table & more C02 means more Green. A catalytic converter is all you really need & fuel injection really helps your engine run more efficient but you'll never reach the mpg standards Federal Bureaucracies have set & they set these standards knowing it will be impossible. If they really want better mpg they should promote diesel engines. What this is really all about is promoting an Agenda that's become a faith based Religion. Government needs to hand the Automotive Industry back over to the Free Market. I know some people try to avoid politics but it's impossible to do when talking about vehicles in America. 1 crazy thing is not all States in America have Emissions Regulations but car manufactures have to build cars that can sell in all States & its an example of how a few Big Government States can ruin an Industry for all States.
Is it possible to purchase a conversion kit back to the traditional thermostat on the cars that have TCV?
@@goldblueberries326 not currently. Likely not to be able to.
It’s hard to beat a good old school thermostat. Tried and true. If it ain’t broke don’t fix it!!
I agree but the blame lies in our government. These CAFE standards to improve gas mileage have gone too far and force the manufacturers to cut corners.
I guess you've never had an old school thermostat get stuck open or closed then?

I have a 2020 forester, so far very happy with it. But I did receive my letter the other day telling me that TCV was covered till 15 years or 150,000 miles, whichever comes first.

@@janelaplant5780 the 2025 Forester doesn't have the TCV? Right?
I'm in Canada, I have a 2020 Subaru Outback Limited I bought used a year ago. Today I received a letter from Subaru Canada informing me that they are extending the warranty period to 15 years for owners of Subaru's with the TCV. Anyone who has paid out of pocket for the repair can now apply for reimbursement. Thanks for the great explanation you gave on the TCV, so far mine is holding out.
So instead of a $1200 metal TCV, Subaru replaced it a plastic one that is 1/3 the cost. Driving down the cost to make a vehicle. Then they're betting the plastic part will last 15 years, but they will warranty it during this time. By that time, perhaps the failure rate of the metal TCV will match, Given that, I think it's a wash
I just visited my local Subaru dealership, they diagnosed this exact issue within 30 minutes and within 3.5 hours they had replaced the TCV with the updated designed component at zero cost to me.
If your Subaru is throwing the codes listed below, RUN do not walk to your nearest dealer. My cars oil temp was running on average 144 degrees prior the repair and had ASS fuel economy. THAT IS NOT GOOD. Low oil temps = condensation in the engine (i.e WATER)

A very good friend of mine had a 1973 Subaru D/L in high school. He finally started to use aluminum beer cans to keep the cylinder-head gaskets from leaking until it finally overheated and died. As far as that plastic valve, plastic can only go through so many heating and cooling cycles until it cracks. I know. I have a 1996 Mercury Grand Marquis with the plastic intake manifold. (IIRC 1996 was the first year.) In 500,000 miles, I have replaced 3 of them. I think that led to a class action lawsuit. GREAT VIDEO!

Subaru senior master here. Been replacing these since 2019 when they were introduced and started failing and have yet to see one come back. The redesign and reprogram seem the fix the issue. Not sure there’s much to worry about with this being an on going issue or a problem that needs to be “bandaged”. I encourage everyone to get their information from the dealer/subaru.
The dealers are full of crap, tried to sell me $2000 worth of unrelated crap then tell me half my electronics were also bad . I only let them do the TCV replacement and magically all my other stuff they said was bad was working properly again. I don’t trust the dealer anymore especially since after they did the work and I came to pick up my car I looked it over and found multiple things they didn’t do, left the main intake vacuum hose disconnected, didn’t replace the clip that holds the plastic part of intake still, other random bs.
Thanks for this. I had this happen on my 2020 Outback at 24,000 miles in 2022. I just got my letter last week . My dealership was awesome, gave me a loaner and had the fix done in about a week . I just hope I received the “improved TCV” . I may have to revisit my automobile choices . I was part of the 2001-2004 Honda Odyssey transmission failures , three replacements on my 2001. Of course I also had a 2004 Forester with the faulty head gaskets . In this case , I should have bought the XT. Next time .
You are like iron filings to the magnet of bad car technology. :)
Exactly. If you want to know what not to buy, check my driveway over the years 😂. I’m dating myself but add a 1979 Pinto, a 1980 Plymouth Volare and an 1986 Oldsmobile Calais. Now you know why I switched to Honda and Subaru.
My wife and I have owned may Subarus because of where we live, Sierra Nevada mountains. Our 9th Subaru , 2023 Forester, experienced TCV problems within one month of taking delivery. It was replaced by a dealer and subsequently experienced coolant leaks with in a month. Took it to another dealer and had the leak fixed. I look at the parts list from the replacement work and noticed items like manifold gasket kit. That was not a quick job to fix. I am disappointed with Subaru making the simple difficult, replace a thermostat with a complex TCV. And then designing and building, I hate to say a substandard TCV. They did not learn from the head gasket fiasco. This in the long run will be an expensive fix let alone a customer nightmare.
They've learned from this mistake, as they have removed it on the 2025 models. All car makers go through this process of research and development, coupled with fuel economy, reduced emissions, cost savings and increased profit margins.
Subaru started building low quality parts to boost profits
@MyLife2020 that's EVERY manufacturer.
You are the Subaru MAN, Dude!
Love how they designed it how to fail optimally instead of how to work reliably
At least make a fail safe design ffs!
With some more fore thought and planning they may have achieved both. Though nothing is foolproof to a determined fool.
This was foreseeable. Plastic and electronics working with super hot coolant.
It's only 80-90 degrees C under most circumstances. An electric kettle deals with hotter liquid (100 degrees C) and is probably made of plastic. Properly engineered design would not have a problem.

Hey, at least they provided the extended warranty on the part. Lots of companies wouldn't do that. Thank you so much for this info because I have two Subarus with these engines. One has 62k miles and the other has 44k miles, no problems...yet. Again, thank you!

Here is the information I found on this there is a law suit. The 85-page Subaru lawsuit says the thermo control valve defect affects 2019-2021 Crosstrek, Forester, Legacy and Outback models (the class vehicles) and can manifest without warning, rendering the vehicles “unsuitable for their intended purpose.” The case alleges the automaker has known of the problem since at least 2021, when it updated the design of the thermo control valves in the wake of numerous failures and a bevy of consumer complaints.
"Unsuitable for their intended purpose?" That is the first time I have heard that used to describe, "Overheat the engine and ruin it."

I've got two of them (2018 Premium and a 2018 Limited) because I wanted the next generation (at the time) while it was fresh. You left out that a 6 speed manual was available back then. Times have changed quickly.
The 2.5 N/A engine is the only with the TCV. All the other F series have a regular thermostat.
I’ve lost count how many thermo control valves I’ve replaced since starting as a tech 😂. I’m not complaining since I get the job done quick, It usually takes me 1 1/2 hours to replace the tcv & bleed the cooling system. The common ones are the Foresters. The Outback/Legacy & Crosstrek I rarely get.
I take it you are a mechanic at a Subaru dealership?
Where is that TCV located at ? Will it let you know before it goes out ?
Yes I am a technician at Subaru. The TCV is located on the left hand side of the engine. Unfortunately no it won’t let you know when it goes out until the check engine light comes on with all the other lights. Most common symptoms are no heat and reduced engine power. As a fail safe the radiator cooling fans stay on at the highest speed to keep the engine coolant temperature as low as possible. Other symptoms which are rare include the car not starting or stuck in limp mode. In rare cases the thermo control valve can completely short out and since it’s in a can-line circuit with other 5V circuits I believe and also share the same ground (tumble generator valves, fuel pump pressure sensor, throttle body, etc.) and can also screw with the engine control module causing it to kinda glitch but it won’t cause damage to the ECM itself that I know of. In this situation the vehicle would have to be towed to the dealer for diagnosis & repair. If you are able to, what I’ve done to diagnose this problem and make the short go away when it won’t start is unplug the thermo control valve to eliminate the short. Looking from the front of the vehicle, It’s a little difficult to get at but there’s a grey connector in the back for the TCV close to the throttle body. The vehicle should start up but it sometimes this won’t always work since the ECM is stuck in limp mode. At that point again, it would need to be towed.
Can you figure out WHY the Foresters so much for failed TCV's? I thought the engines were identical when you opened the hood of a 2024 Outback vs the Forester 2.5L.
Remember that the Foresters are built in Japan and the Legacy and Outback is built in the US and possibly different lots of parts or even different manufacturers of the parts.
This happened to my (former) 2020 Subaru Outback at around 45,000 miles. I was on a long road trip and couldn’t get it in right away. Fortunately, the valve defaulted to open, so I was able to get home for service. It was a long drive without some of the features, and lots of dash lights came on. Neither the oil nor the coolant got to normal operating temperature. I know folks might not find this rational, but I was so frustrated and disappointed that I traded it in for a Honda. I still have a 2016 Outback and a 2011 Forester, but since I do so much long-distance driving, I lost trust in the vehicle. Fortunately, Subaru did step up and replace the part at no cost, but I couldn’t regain the confidence in the Outback.
Any problems for you with cracked windshields on your Outback? That's my main concern in looking for a good slightly used Outback.
No windshield cracks at all.
Bryan, I meant to inquire: what Honda did you get to replace the Subaru?

Check the post from @camerondaley1481 right above your comment. He has not seen a failure since the redesign in 2022.
What is designed to meet EPA & bogus CAFE standards, ends up causing more pollution and fuel use with towing, parts distribution, and testing the vehicle after the replacement is installed. Then the trips to and from the repair facility.
All makes sense, right????
Bought a lower trim model Outback (Premium) specifically to get less problems (no turbo to fail and less nanny features). Funny how sometimes all a company has to do is nothing and they can't seem to pull it off. I totally get that all mechanical components can fail, but this seems to be overengineering at it's worst. Thanks Mr. Subaru, you are my go-to guy!!
I just graduated college and decided it was time to finally get my first car. I was shopping for a Subaru Crosstrek and ended up getting a Subaru Outback instead. I was excited because i got it for a decent price used of course because i have money saved but I'm trying to get to grad school. It has only 56,000 miles on it and is a 2020 no less! I was skeptical about the eyesight system and scared any problems with it would be catastrophic in terms of repairs and calibration. I did my research and felt pretty safe seeing as the head gasket issue has been addressed (relatively, still not a fan of the silicon gasket). But after having it for a week the battery died. I don't blame Subaru for that, it was the dead of winter in January and the car had been sitting for a month or two before i got a hold of it. Then comes just last month. I have only put about 1.5k miles on the car so far and my check engine light comes on after driving for only an hour straight and i loose the eyesight and x-mode feature. I pull out my OBD scanner and sure enough it was the Thermocontrol Bypass Valve. No warranty, completely out of pocket I'm going to have to find a way to fix this. Luckily it stuck open and im just stuck running cold. I've loved the car thus far but idk if im starting to really regret my decision or not yet. Im trying to get settled and start working multiple jobs and get a new apartment so i can make money to get to grad school but im wishing i just bought an older model toyota with less cheap and modernized electronic bells and whistles at this point.

Another awesome video. I had this happen to my 2021 CrossTrek Sport about a month ago. Freaked me out especially when the eyesight went out. I’m past the warranty thresholds so the worry about cost was real. Dealership replaced under the extended warranty and they said they had seen and replaced a ton of these recently. The dealership also told me without Subaru’s extended warranty it would have cost me around $1800 (part, labor, taxes, etc)!!

I just bought an Outback Touring XT. I guess I don't have to worry about that failing now, just the turbo. Haha My wife has a 2017 Nissan rogue and we were looking to trade that in for a Forester, we just weren't sure if we were going to do a 2024 or a 2025. I guess going with the 2025 will lessen the chance since it no longer has that part.
Yep. My 2019 forester had it. Luckily got it fixed under warranty
Polycarbonate plastics really don't like many types of chemicals. The polycarbonate "windows" in modern computerized lathe housings become brittle over time because the coolant splashing on them during the cutting of metal. This can be really dangerous if a part flies out of the machine. So It's just a matter of time before they crack. I mean it's inevitable!
It's too bad more of the aerospace quality plastics haven't migrated into cars. They continue to use crappy ABS and polycarbonate plastics.

Had it taken to the dealer and was told that the TCV had failed and was under warranty NO CHARGE! (Tow Bill : 365.00)

When I was a VW tech , around twenty years ago they introduced the limited production W-8 engine. It too was equipped with an "electronic" t-stat with a very high failure rate. I performed several repairs regarding this component, typically caused by the engine not reaching full operating temperature as you described in the video, along with the requisite trouble codes. Coolant leakage was not an issue on this problem.
Thanks for the heads up bud ...I have two 2024 Forester Sport models. 🎉
Oh well lol. 😊
My 2020 Legacy was at a Subaru dealership for TWO MONTHS for a CVT issue (valve body ended up being replaced) which was resolved last week. Needless to say, it was an ordeal. I went to work this morning and every light on my dashboard went off like someone had missile lock on me so I drove it straight back to the dealership assuming it was related. "Here we go again..."
Turns out, it was this issue and everything is totally covered! They had it diagnosed by 8:45 this same morning and I should have it back before the day is over. Some good news for a change!
Great video, btw :)
Never seen a single redesigned TCV fail. Also never seen these things fail "closed". 100% of the failures I have seen led the TCV to remain open. Once an issue happens the fail safe will open the TCV fully. Also this isn't a "New Big Issue! omg!". It's been known for a long time. They have had a redesigned part since February of 2022. They finally got off their rears and extended their warranty but these things don't get stuck closed and if it does, there is plenty of warning before the vehicle over heats. Don't ignore check engine lights.

keep the awesome content coming my man! helping me diy my way to 250k miles
Thanks for heads up on this TCV issue. I'd rather not gamble with the lives of my family. So, it's a hard pass on the Subaru brand. I really liked everything it offered. Too bad the company won't actually fix the problem by going back to what has been a reliable part, and easy to change.
I have a 2019 Forester. My TCV went out at 115,543 miles. I guess it was stuck open as it was not overheating. Eye sight disabled, cruise disabled, chech engine light flashing and greaty decreased MPG. Codes present B2806, P26A3 and P26A5. No waiting on parts but it was fixed at the local dealer for a total of $1602. I just recently filled out the reimbursement paperwork and submitted it. Waiting to see. It seems like every year/ model car has some type of problem. My rear sway bars fell off at 600 miles, both front CV axles replaced at 100,000 miles and keeping the battery charged has been a pain.
My $.02: if you are still running the Subaru factory Panasonic battery, get something else. They suck. I’ve been running either Duracell (really!) or X2 in all my cars, work great.
I think your Forester is part of the battery draining class action lawsuit, correct me if I’m wrong. Maybe it was just a service bulletin. Regardless, several model years of Foresters, Outback, Legacy, (maybe Ascent), and Crosstrek, around years 2017 to 2022, has had batteries that die really early.
@@nowiecoche Our 2015 Forester's battery was replaced under warrantee. It didn't last 2 years.
I've got a 2020 Forester.. It needed the TCV replaced last year. Now I'm hearing a creaking sound at low speeds, especially when I'm turning. I'm guessing it's a CV joint somewhere.. Can't tell if it's coming from the front or the rear.. I've been thinking about replacing it with something new within the next year.. Might just have to do it earlier, rather than later.
Nice to see them go back to what works! Not many companies would do that!
Suddenly my old '15 Outback doesnt look so bad... 😉
Still driving my 2001 Outback 😊
...or my 2005 Outback.
My 2014 Forester is doing quite well. My favourite car was my six cylinder 2010 Outback. Sold it when we went down to one vehicle.
@@jimclarence5441 My 08 225 000 klm EJ Forester goes strong, but I'm on tenderhooks waiting for the Head Gaskets to go!
As you stated they all have issue! I have 18 outback with exceptions of the radio so far so good. Which is why I watch your videos To learn up coming issue! Thanks
mine just failed not too long ago, and it failed open for bypass. i was under warranty. after dropping my car off and got home i just got the letter in the mail for an extended warranty
Mine failed open in November 2023 with 18K miles on my 2020 forester, the dealer replaced it no charge.
I would buy a Subaru if I lived near this guy--great traction and fun to drive--but I just don't have a go to mechanic like this with a real passion and knowledge for the vehicles.
Toyota is the reason I like Subaru. If they didn't team up to make the 86, I never would've gotten into them.
The 86?
Brz frs 86 same vehicle
I have a 2015 Outback Limited 3.6, currently just turned 99,000 km (Canada). Purchased new, it hasn't given me a single issue, I follow all the recommended services.....and some, approximately 5,000 km between oil changes. My wife is thinking about a new Outback, I'm reluctant, this Subaru has been great!
This happened to my 2020 Legacy last summer. Scared the crap out of me seeing all those warning lights and the engine just died. My dealer did the repair under warranty, and apparently in my case, it also blew up the engine wiring harness which also needed replacement under warranty. The loaner car was nice, but it was a two week process. I wonder if the extended warranty also covers the replacement components. Thanks Mr Subaru!
Well snot balls! Just got a 1 owner 2019 forester with 6900 miles from the dealership, got the letter in the mail last week. Time will tell.
Thanks Mr Subaru for the diagnostic tips, great information.
I put 90k miles on my 19 Forester with 0 issues. Gas/oil/tires. As promised.
Almost 90K on my 2019 Forester purchased new - knock on wood, but no issues with it so far. It's been a really good car so far. The infotainment used to mess up sometimes but I think a recent software update fixed it.
I bet some of it comes down to how easy it is to make one outta recycled materials. They're committed to the net-zero waste stuff. Absolute guess, and I don't know anything about anything.
A big thank you to Mr. Subaru for this video. I watched this video about a month ago and verified that both my wife's 2021 Outback and son's 2021 Forester have this part. I downloaded the service bulletin and gave my dealer a call. The told us we would have to wait till it failed before it would be replaced. They said we could contact Subaru Customer Service but that would not do us any good. Well today 9/1/2024 the unit failed, thankfully it failed open and we were able to drive 25 miles back to the house. Had I not seen this video I really would not have know what was going on. My wife's Outback only has 26000 miles on it since we are retired and do a lot less traveling. The car is her baby, garage kept and well serviced. Two months ago the OEM battery died of course out of warranty. Subaru did give us a voucher for $250 after I complained. This is our 3 Outback, we have owned two 2015 models and I still have my 2015. They have had some issues but nothing like this. While I am sure the car is still safe to drive it sure is not instilling much comfort for any long trips. At the very least they should be notifying those owners with this issue by mail .
I just looked under the hood of my 2018 Forester...
Aluminum TCV! Phew!
If i trade, it's gotta be a 2025!
Thanks, Mr. Subaru!
2018 doesn’t have a TCV. Just a normal crossover pipe and mechanical thermostat.
@MrSubaru1387 Thank you. There is a disconnect between my brain & fingers... that's what I meant to convey. You are my go-to Suby advisor. Thank you, and 2 thumbs up for your channel, sir! 👍👍
Mine just failed 3 weeks ago. 2019 Forester. 95,000 miles. Dealer warrantied under the new 15/150,000 warranty. One day repair. Only issue so far with this vehicle.
You have the Best Subaru channel on RUclips!
Thanks for sharing your knowledge. I have a 2013 Crosstrek that I bought in 2017
I'm glad you did this video because last night my wife's 2020 Forrester started doing crazy things, i watched this video and it answered all my questions, my TCV is bad and luckily it failed open. Thank you!!
Mine just failed.. before I drive it to the dealer (2 hours away) how do I know it's failed open ??
We can all thank the EPA for sacrificing reliability with parts like this for us…..
Yeah, too many points of failure.
Absolutely, too many points of failure.
@@AJKPenguin Lexus GS/IS 350 has a plastic tstat elbow since 2006. Never an issue.
THIS IS A POSITIVE +......
It's subaru, not the EPA that designed this part. Quit giving a pass on faulty engineering.
The old coolant crossover pipe was the first and biggest failure on my '05 WRX STi. Warranty repair thankfully, but still hurt to see the engine pulled out of my new car at only 4000 miles. Glad I gave Subaru a 17 year break to see they made it worse. Hopefully the '23 FB25 revised part isn't failing as much as the '19-'21.
You would think that Subaru would spend a little more time testing their stuff before having "issues" and having to go through multiple revisions to get it right. This seems to happen with everything Subaru comes out with. Like get it together R&D department!
They did test it,they let the consumer test it.I see more and more of this on late models.Too much stuff added on to please uncle grinch.
this is the stuff you expect form Hyundai, Nissan, GM, VW, etc
Bought my 2020 Forester certified used last June (2023). Got the letter from Subaru about extending the TCV warranty first week of May, and then of course a few days later (5/10/24), it failed driving home from work. Luckily I had just left and was able to pull over into a parking lot right away. Dash lit up like a Christmas tree, car wouldn't go over 10 MPH, and engine revving up and down non-stop. Dealer confirmed that the TCV failed, and also found a faulty intake manifold. Both replaced under warranty at no cost to me. When I got it back, the car ran great, although it seemed to run a bit rough when starting cold, and smoothed out when warmed up. Had the car back for 14 days, and again, leaving work had the same issue, minus the engine revving high and low. Dealer says there was some carbon buildup, and they are doing a "deep decarbonization" of the engine, and also caught a misfire on cylinder 3. Not sure if these are related to the TCV, but the car ran absolutely perfect until the TCV failed. Hopefully I'll get it back in the next day or so...yikes.
uh yup. our shop replaces 2 or 3 of these in a week on average.
And what's wrong with them? Have you analyzed?
Just happened to my '21 Forester at 59K miles. Got the typical symptoms of all warning lights coming on and driver assistance systems being disabled. Took it to the dealer this morning and all is good and no cost to me. Got a nice Outback loaner for over the weekend while they do the repair. Good job to Jim Keras Subaru on Hacks Cross Road in Memphis. Hey, shit happens and cars break. At least Subaru is covering the cost and doing the right thing.
Well damn. My wife has a 2022 Crosstrek, and the winter of '22-'23, for about 3 weeks in the Alaska winter, the engine would not warm up, stayed cool with no cabin heat. I figured the thermostat was stuck open so I got an appointment with the dealer....4 weeks out. In the meantime it started working correctly and worked fine last winter. Keep an eye on it?
I suggest reporting it so your shop can log it into the records. If it ultimately fails after warranty, it can be traced to starting to fail when first logged, hopefully within the warranty period.
I have a 2024 Crosstrek Limited with the 2.5. I immediately noticed that on cold days, it struggles to warm up and stay warm. I figured maybe a bad thermostat, but that’s extremely rare on a new car. Now I know why….
It’s not just Subarus, I’ve had multiple Kia/Hyundais come in with the same issues.
The new 21319AA040 valve part only cost 288 online. The one time use gas line is 54. New gaskets about 6 bucks total. Add in some subaru coolant and the total for me came to 399. While my 2020 subaru forester has no issues yet I would rather swap this in now because realistically you could end up spending 200 for a tow to the dealership plus the down time of not having a car. Add in the fact that if this happens on vacation you could find yourself having to cancel or extend plans. 400 bucks to keep that from happening is worth it to me. Ymmv.
Not only is it going to be hanging over our heads, but after 15 years, they won't have to even keep parts.
I find it hard to believe that with modern prototype testing that they didn't already know that there were going to be problems. How else could they come out with a "fix" so soon?
this is the stuff you expect form Hyundai, Nissan, GM, VW, etc
We bought a 2020 3 weeks ago, it took 3 days before we got a P26A3. Fortunately it's at only 112k. Scheduling the repair at the dealership this week, very glad to have found that warranty extension before paying out of pocket at our local.
Hopefully the replaced TCV holds up until there's a retrofit kit to put the 2025 crossover pipe on and a DIY ECU flash to go with it!
Just set aside $2k for this repair every few years and just deal with it. You did buy a Subaru.
so now i have to worry on my next road trip. need to pressure sba to recall instead. once consumer reports gets on this there goes their reliability ratings. I wish mine would fail already to get the new part. My dealer said they won’t preemptively replace unless it throws codes
There’s a class action lawsuit. Forgot to mention it in the video.
just bot a 2024 Crosstrek...so glad I just now found out about it after I just bot it...wonderful. Im In NC
My ‘23 Forester Premium has steadily been losing coolant.. I have to check it closer.
Edit: I just remember, the safety systems on my car were shutting off randomly right after turning on the car and started driving, then the CELs would turn off on their own (this has happened 3-4 times in 6k miles)..makes me wonder now if it’s the TCV failing.. 🤔
Wow. My daughter and I were considering an Outback or Forester. Previously have had several Volvos since 1989 which all were very reliable, and survived accidents. Now too expensive, so looking at Suburu. Thanks for video and explanation. I’ll be holding on to current 2011 Acura RDX until it’s done.
2016 crosstrek premium 96000 miles, running well. Just basic maintenance. Simple.
First coolant service is what 10 years/100,000 miles? I don't think maintenance will help these TCVs last longer on Subarus that have them. Unless maintenance means "replace the TCV before it breaks" which seems like getting into German car thinking, lol.
Once I started seeing the problems around RUclips and seeing with my own eyes the electrical gremlins on my top of the line Legacy, I decided to switch to an Alfa after 2 years despite I purchased the longest warranty and I could never be any happier!
In 2 years of Subaru I had to go twice a year for services plus other 3 times to fix electric problems in the car that were not solved because after re-using the car, after having the whole system restarted, it would still give me the same problems. In other words I went 4..5 times a year to the dealership, a real pain. With my Alfa I have to go only once a year and it has been way more reliable and capable vehicle than Subaru under every single aspect.
As a subaru tech i HATE flipping the bill for these shit thermo valves. Retail pays 4 hours but subaru pays 2.6…
45-1hr repair is about where I’m at now after doing so many

Good information. Wife was considering getting a 2022 Ascent to replace her 2014 Forester with 281,775 miles and the front oil leak. Something to think about as well as fixing our oil leak / reseal. If you're interested in fixing our leaks, we can drive the car down from Virginia and drop it off.
I suggest going with HYUNDAI PALISADE better in every corner
You would think cars have been mass produced for over 100 years that they could build a car that should be truly reliable by now.. I for one am getting sick of this shit. For one thing this part should be full replacement for the life of the car not the owner it was and is there f...k up.
It's is about cutting manufacturing costs.
I don’t see how this would be cheaper than what they had..
@@MrSubaru1387 Agreed, replacing all those TCVs on the road under warranty will cost them big time. Another great video!
Thank you so much to give me this information. From a Chinese outback user
Thanks!
Thank you so much!!!
Thank you for this video!! I was ready to get a 2024 forester for my Wife but now wait for the 2025!!
