I am experiencing a engine noise that I am not sure is important or not. the noise sounds like a "spark" knock under modestly heavy acceleration. My Local dealer does not have anyone with experience working on these cars. One guy at the dealership said it was normal another said he couldn't hear it. The car is under warranty so I guess I need to go to a dealer. My Question is does anyone know of a dealership in southeast to mid michigan that has qualified service techs capable of doing quality for this type of problem. I really don't want some inexperienced tech working on the engine. Thanks
