Not covered under warranty due to modifications. Now if the car is bone stock, then the consumer has a valid warranty claim.
NO, the aftermarket parts MUST be proven to have direclty caused the problem. Dealers will try to pull that on you, but if you know anything about your rights they will change their tone quick.
Read up on the Magnusson-Moss act that was posted above.
I had my entire motor replaced under warranty, since it smoking and burning oil, and I had aftermarket parts and some were even illegal. They said they were going to void it because of them and I told them I would see them in court. A week later I had a new motor. So, if you know what your talking about they will fix it. Now, if your mods prove to be the cause then thats different.
As far as the Mistsu/Subaru warranty stuff it's pretty much old news. They look up the auto-x results or call the group that you ran with to get the proof. They do the same thing with drag strips.
Solution, use a fake name and dont let anyone take pictures of you at the track.
The dealers I use know I race my car and I havent had ANY problems getting things repaired. This goes for new motor, tranny, and axle bearings in this car. Mistu/Subaru are getting raped on their AWD transmissions, so there taking claims very seriously.
