Default will Subaru most likely deny a claim for throwout bearing base on a Cobb stage 2+?

I want to start this off by saying I take care of my 2014 WRX it has just under 20k on the clock, oil changes happen between 3-4k miles and while I do enjoy some boost every now and then I don't "drive it like I stole it" or beat on the car regularly. I bought it with about 7,500 miles on it.

Shortly after I bought the car about 4 years ago I had done Cobb stage 1+. I had kept my eye on the logs and it seemed ok since I did that, nothing bad came up in the logs. A few months back I had an issue where my car would refuse to go into 4th gear when downshifting. It happens rarely, but usually it would act like the gear was locked out, kinda like if you try to downshift into first and you are going to fast before the gate will open and let you downshift into that gear. You could pull the gear lever back but it would not move back into 4th. At first I chalked it up to me just not being used to the WRX transmission, and miss shifting (coming from a 240sx where it was very silky smooth, with a very different clutch engagement, the WRX transmission is very different).

After it happened a few times where I was going slow enough that I decided it was not me getting used to the car, I decided that I would take it in to a dealer to look at it. Before the appointment though I got rear ended getting off of the highway, thankfully the damage was not very bad, I was not in gear, just the rear bumper and the exhaust were damaged.

At this time I thought to myself why not go cobb stage 2+? Not really thinking about the warranty my car still has, I had to buy a new exhaust anyway, and I had found really great deal on a Tanabe T70140 Medalian Exhaust, that made it cost less then buying the OEM replacement. I picked up a catted downpipe from Cobb, and I installed the stage 2+ map.

I also had my mechanic install a block heater while the car was in to have the radiator fluid changed. At this time he mentioned to me that when the car was not moving and he depressed the clutch pedal he could hear it make a groan noise, and while it is not loud it is something you can hear from the outside of the car. My mechanic believes that with the noise and my intermittent issue getting into 4th it seems like the throwout bearing is going, and I am inclined to believe him.

At this point I understand that my mods will most likely void any warranty on the engine or turbo there's about 1.5 yrs left on that (out of the original 7yrs 100,000 miles CPO warranty). I took that bet and I am fine with losing those, I take care of the car and I think they will be fine. I am worried about the throw out bearing not being covered, because of stage 2+. Obviously I can't put my car back to stock with a full turbo back system, should I reset the ECU to stock maps? I still have the Cobb intake I could put that back to stock, but I feel like it would be noticed anyway because of the downpipe and exhaust.

What should I expect? what do you guys recommend?

no thoughts? My appointment is tomorrow, I am going to return the car to a stock map. I am sure subaru will know what's up, but I guess that's all I can do for the time being.

My mechanic looked at it as well, the noise kinda sounds like the noise your car would make if you turned the steering wheel all the way to the lock on one side, and you were still forcibly pushing the steering wheel towards the lock. But only makes the noise when the clutch pedal is depressed.

I have not heard the noise a bad firewall makes on a subaru, but I imagine that it would make a noise as you press a pedal down, and then that noise would stop if you held the pedal down, because the firewall would be flexed at that point. This noise in a continual mechanical groan, although not loud it is audible from within the car and is constant as long as the clutch pedal is depressed.

Honest question would the firewall flex cause a mis shift like the issue that keeps me from going into 4th on occasion?

EDIT: I do want to be clear that the clutch pedal makes a sound not just in the action of pressing it, but the whole time you are holding it down as well. If the car engine is off for instance there is not any noise if you press the clutch pedal down.

You wouldnít know for sure without taking it in. So just take it in and see what they say. Donít try to pull the wool over their eyes just be honest. If they have reason to believe that the issue was aggravated or caused by the mods then yes they will probably deny warranty coverage for that issue.

Tried doing it this way, and it seems to have worked out well. Told the service advisor that the car was modified after the accident, and that the noise had been occurring for awhile (thankfully I also had documentation of this as well). The Service advisor told me that they would have to take a look at what was causing the noise and that it could not be covered if they determined there was any abuse to the car. After an inspection they said they would cover the throwout bearing, and that there was also a noise in the firewall that they wanted to look at that would most likely be covered too.

It looks like Subaru is willing to honor the warranty if it looks like the car was maintained and that the issues are not happening because of owner abuse.

Too late to chime in I guess.

Surprised to see that the gurus on this forum haven't responded to this post. They could probably give you a better answer, but here is my take.

Not surprised that the warranty covered it. Typically, if mods caused the part to fail, then warranty would not cover it. If the mods had nothing to do with the failed part, then it should be covered. I don't see how a Stage 1+ would cause the throwout bearing to fail. Plus this seems to be a common enough known issue (at least according to these forums), so that probably helps too in getting warranty coverage.

Glad to hear it worked out for you.

so looks like if the mod didn't cause the issue then it s covered. This is alway been the case but it s good to see it work out in reality. Probably a good dealer to stay with too. I assume you acted professionally and courtesy too , which never hurts.
