While I was talking to my dealership over the phone the other day I just happened to mention something about something I was about to do to the car. Soemthing about a turbo back exhaust. The guy then told me "oh...well that will void your warranty so you might want to think about that". It wasn't an issue at the time so I didn't get really deep into it but every one I've asked so far has told me about an act that says that the dealership has to prove that the modification is what caused the problem. I have a feeling that the people at my dealership aren't aware of this. When it comes time for me to need to get something repaired, how shoould I go about dealing with it because they are hardcore convinced that anything done to the car completely voids the drivetrain warranty.
