I am new to the forum, so this is my first post.
I have a 2011 WRX and I have had it in the shop 3 times since it had about 7500 miles on it. First time it started misfiring my dealer said it was a bad mass air flow sensor in the exhaust (never heard of one in the exhaust). I got it back and immediately the engine started misfiring again and actually died at a stop light it was missing so bad. They took it back, cleared the computer and said they couldn't get it to happen again. I had the car for 5,000 mi after this, hearing occasional misfires, but I decided it didn't seem too bad and maybe it was just the way it runs. A few days ago it began misfiring again badly and the check engine light came back on. I took it in and now they are saying that there is a software update for it.
I am looking for peoples opinions here. I already wrote a letter to SOA explaining the situation ( in more depth) and also telling them that the dealership has not done a compression/leak down test. What do you guys think I should do? What I am concerned with is that the engine will fail after the car is out of warranty and subaru will get out of it scott free. The car currently has 17000 miles on it, has always had service done on time and no mods except shifter bushings.
To anyone with an engine failure due to valve issues, did your car have similar symptoms and what did it take to fix it?
Thanks for the help.
