Hello. I am new to the forums but have been reading for a while. I have an 05 STS with Nav and had a question. I read about the starter button being replaced while the car is still under warranty and took it in to the dealership and got me a new button. So that made me wonder what else they would replace. My headlight lens is doing something funky like peeling or something like that. Does anyone know if they would replace them?? Also what else have people gotten replaced under warranty??
