This dealership sold me a Chevy traverse this February and 3 weeks later the battery died, I have no control over the power window of the passenger side from the driver side and the blinker light on the passenger side went out. I took my car back to the dealership and I was told pretty much that s my problem now. There is no reason why my battery should be dead after 3 weeks and you not even try to help me!! So when you buying a used car from any of these dealership you need to do a routine PMCS (Preventive Maintenance Check and Service) came back from deployment to get scammed.
