You admitted to launching your car what a half dozen times withing 6k miles? Now also you proved that you obviously never owned a wrx before but claimed to drive stick for a long time. I don't care who it is a subaru is a different beast especially when launching. You being a rookie probably thought before launching "hmm I don't wanna blow my trans so let me slip the clutch just a little bit more then I should." It only takes once to form a hot spot or even really badly glaze a clutch and flywheel.
Next fact. People come in saying they launched their cars. Ding ding. As much as you forum guys think you can pull a fast one on subaru dealers it's not difficult to tell the ones who beat their car and who doesn't. Then when we take the trans out all we have to do is look at the clutch and all the hard spots.
I guess final fact. 2010's where's the clutch problem? Every time I mention the 2010's that have the same exact clutch in it you never say a thing. You're so hung up on this 2009 thing.
So as I wrap this up I will comment on your last ditch effort to try and throw a zinger at me and how silly I must be. Yes I am way more in the know then you will ever be. I work at a dealer. and deal with guys like you all the time. My service manager (the guy who makes the call) is a very forgiving manager and warranties way more then he ever should. And just to prove you wrong again I also called tech line to ask if there is any known clutch issues with the 2009 and the answer was no.
Just in case you don't realize what tech line is for subaru it's a number we can call and talk to operators about a problem we may be having. I guess the latest one would be the 09 outbacks that would leak through the map lights from the sunroof track. Had one leaking called them and they told me what I needed to do. They open a case number so they can keep track and see what the problem areas are. Therefore there are no known clutch issues that isn't due to driver error. Try a driving school maybe?
