I’ve read that a class action lawsuit has now been filed against Subaru for knowingly ignoring a TCV design failure that caused premature rusting and roadside failures. For the longest time affected folks were told it was not a warranty part. Now it appears to be covered for five years. This affects all 2019-2021 Forester, Crosstrek, Legacy and Outback models. It seems like all engine types are affected.
Thermo Control Valve (TCV) Class Action Lawsuit now underway.

my 2020 limited Outback was retrieved this morning from the shop with the new tcv installed. Drove less than 5 miles, car came to a screeching halt on the highway, every light on the dash illuminated and the car stalled. Barely got off road and almost got run over by an 80 mph semi. Had it towed back. Now wondering if install went wrong or what. Any thoughts?
Did you smell coolant or see any steam from the engine compartment?
Sounds like a poor install. Sorry you have to go through that.
On a side note, I just installed one today in a customers car. Figured I would take some side by sides. No exterior difference. Will see if I can post them from my mobile.
(Edit, wasn't elliottdonna66's vehicle I was working on lol)

Judging from your pictures, you can clearly see the manufacturing date clearly on the unit. I wonder if it Is visible after the installation?
I believe it was noted earlier in the thread that it is NOT as it's hidden by the intake or some other part that needs to be removed for the repair.
This part just failed for me on my 2021 Outback at 62,000 miles. Repair nearly $2,000. I've appealed to the Subaru advocacy folks to see if they are willing to help. Anyone have any success getting them to help this close to the warranty expiration?

My 2020 Forester had this happen last night on a country road in the rain. I could not drive it at all. I had it towed to the dealer -- thank god for AAA!! The dealers say it's under warranty but I haven't talked over what will happen going forward. If it's replaced by the same part what is to stop it happening again? Very disappointed in Subaru.
The TSB posted earlier in the thread indicates a redesigned and more robust (internally) part is the replacement.

I just had the TCV failure last weekend on my 2020 Outback Touring, the symptoms I observed were a solid check engine light, eye sight disabled, RAB disabled, Front collision warning off, essentially christmas lighting on the dashboard and NO Heating from the blowers. The dealership tells me the warranty will cover the part but they do not have it readily available and will have to be ordered, the vehicle is still with the dealer meanwhile I am wondering if the replacement will be the same plastic made TCV or will the replacement be any better? Also does the replacement come with any warranty?
I put photos up just a few messages above this. It's appears exactly the same on the outside but internals are improved to prevent damage to the inside.

Thanks for your response Devilhog, so the new replacement is more robust I hope? Is it a new part number, I mean how to confirm which one the dealer used as a replacement? Also any information on the warranty of the replacement?
Yes it's more robust. And the part number is mostly the same. They usually only change either a single letter or number depending on revision. All their parts work like that.

The TSB specifies that all dealers should use the new improved part, and they no longer sell the old part. Unless the dealer was totally incompetent and installed an old stock part, you got the new part. Changes include a new waterproofing treatment to the sensor, and a new stainless steel internal shaft, which will hopefully prevent corrosion and leaks in the first place.
I have had some experience with recalls and major part redesigns in another industry, my experience is the manufacturer will order all their distributors to send all their old stock back, to prevent a customer from having a negative experience with the same failure twice should a known-faulty old stock part be installed.
Your warranty continues as previously agreed to, unless the dealer gives some additional warranty on their work.
Yes it is under the intake manifold.
I'm currently waiting in a dealer's service department after a P2682 code appeared while on a road trip, currently 500 miles from home. Guessing I'm going to be told it's the TCV. I'm at 67K so just outside of the powertrain warranty.
Hope they can get it replaced quickly and get me on my way, ugh.

This is an expensive repair due to the labor required to get to the TCV. Save your repair invoice and reach out to SOA when you get home—see if they’ll reimburse you for some of the expense.
I saw some older posts where it looked like some people might have had success with this. Definitely will be trying since I'm just outside of the warranty, and there is a TSB about the part's deficiency.
Service Dept here seems baffled. The light was off by the time I got in to the dealer, went away after the engine was off for 30min. The code is not showing in the memory. Glad I took a picture of my code scanner when the light came on this morning. I didn't clear codes, weird it's gone.
