I am having the same issue. I took the car to the dealer and the service supervisor told me that I have an "Aftermarket Exhaust" and that this is what is causing the problem. He also tried to scared me saying that having such an exhaust voids my warranty which I know is not true, what I have is a Borla axle back. Then he told me that he was not going to report that I have an aftermarket exhaust, that if i wanted to get the car fix I needed to put the factory exhaust on. What should I do about this guys?
