Talked to dealer about extended warranty since I have had a few problems with vehicle since I bought it new. Said call soa.

Cobb AP with E tune

Cobb flex fuel kit
Had about 30K on it since modding it.
Fuel pump started acting funny, hesitation fuel spikes, probably due to cold weather and too much ethanol. Added some 93 to bring it down. Ran fine next day for about 75 miles until I did a WOT pull. Let go around 6K rpm just as I was about to shift.

That sucks. Isn't there a fuel pump recall? Not sure if it is related, or whether you had swapped it out considering you are on flex.

Model/Year: 2014 Subaru WRX hatchback
Milage: 109k KM
Mods: Cobb intake - Cobb stage 1 - Muffler Delete 4"
Fuel: 91
I had cobb installed around 107k km with intake

Circumstances: Started hearing a ticking sounds coming from my engine, waited to long to actually check the issue - car died in street.


Actual engine failure: Crank bearing went on my engine.

Solution: Dealer passed a brand new engine under warranty even though i was over the 7 year 100k km engine warranty. Guy from Subaru said to remove COBB since it tends to blow engines (in his view after seeing so many engines blowing to that) and go get a proper tune instead.. I'm taking everything out except muffler lol.. Don't want to chance this again.

ALSO if you try to unflash your COBB before bringing it to Subaru they can see you did that lol as i did that

thanks!

Does that sound like a smart plan to you guys? Most of my driving is a 30-40 minute commute twice a day mostly at highway speeds, with some back roads blasting on the weekends. It's Texas, so it's going to be getting hot here soon, and for now I'm off of the ethanol and just running MAP's stage 1 93 octane tune.
Glad to hear the stealership was able to rebuild! Texas here too, DFW. Question, what back roads and where locally?

Thanks.

Thumbs down Stage 1+ CVT

Model/Year: 2019 WRX Premium
Milage:39,000
Mods: Cobb sf intake, boomba bypass valve, stage 1+ cobb ap OTS tune
Fuel: 93
Oil: motul 5w-30
Circumstances: only 2.5k miles since I installed the intake, bpv and ots tune, I noticed a ticking in engine that was noticeably louder than normal but not obvious enough to assume as rodkncok. I assumed it was just the injectors but I could hear the ticking from inside the cabin which was unusual.
Actual engine failure: cylinder 4 left the chat

It is a cvt. I confirmed with cobb re transmission and the tunes were for cvt. I’m not sure how I ruined the engine after 2.5k miles of having the tune. Bpv had no boost leak, I did oil changes every 3k miles. Is it possible the tune wasn’t dialed in well enough for automatic despite cobb confirming? Could it be from doing pulls ~3x a week? What’s the point of having a car like this when it can’t handle it?

Any ideas as to what could’ve gone wrong will be helpful. I don’t know if I want to keep the car if it can barely handle stage 1+.

Has anyone running Ti valve spring retainers seen any excessive wear or failures?
