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.

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.

[@michaelking42]

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.

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.

[@WLEE100]

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

[@bryandepoy8030]

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.

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.

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.

[@willmenv3566]

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.

[@jeffstone28]

I take it you are a mechanic at a Subaru dealership?

[@alanlangley7246]

Where is that TCV located at ? Will it let you know before it goes out ?

[@willmenv3566]

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.

[@ofcbob6391]

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.

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.

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 just got the notice last week in the mail for my 2020 Forrester.

[@JimL73]

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.

[@allie_nord]

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

[@allie_nord]

If they end up changing the design for a newer Outback model I might just spring for a new one.

[@jtraveny]

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

[@rudedog302]

Mine failed open in November 2023 with 18K miles on my 2020 forester, the dealer replaced it no charge.

[@jamesdarcy3902]

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.

[@Katya5cat]

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?

[@ronharris9829]

[@Rich_123]

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.

[@CedroCron]

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!

[@bobwendoloski6970]

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 .

It’s not just Subarus, I’ve had multiple Kia/Hyundais come in with the same issues.

keep the awesome content coming my man! helping me diy my way to 250k miles

[@missletoad]

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.

[@thomas735]

This is happening on our ‘19 Forester. Subaru issued an extension of the warranty to 150k miles, and will cover it. Kinda sucks to have to deal with but I understand that they have to do what they have to do for fuel efficiency standards. At least Subaru is fixing it unlike Ford or GM.

I have a '21 Crosstrek with the 2.0 engine, does it also have this ticking time bomb, or only the 2.5s? One more reason I wish it had a real coolant temperature gauge instead of the silly idiot light. I would gladly trade the useless "MPG" gauge for something that actually helps you monitor a critical engine function.

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.

[@Mike_44]

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.. 🤔

[@Cavediver762]

Planned obsolescence. This is the biggest issue with newer vehicles. We have essentially no better mpg since the 90s, and cars are approaching an entry point of 40 grand. We have disposable cvt’s and similar engineered systems that discourage user serviceability or worse. At what point do we wake up and realize we are in trouble? I would almost take a vacuum advance with points these days.

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.

[@craiggillette4381]

Mine blew, perhaps simultaneously with the low pressure fuel pump. 2019 Forester Sport. I looked up things waiting for the tow truck. At the time, the reporting/bulletins had a range of models and production dates. Neither should have applied to my car. But, I had the full extended warranty and aside from getting the parts in with a bit of delay, my only "problem" was moving stuff from my car to the loaner to continue my trip. The Service adviser was a bit confused by the codes and the way the car stuttered along, replaced the TCV when they got one, still had codes and stuttering, tracked it to the pump, got one, replaced, it and it's been fine since. However, sudden dash lights and 4 mph max speed directly from freeway speeds was un-nerving and I was able to get to the side safely.
