This car has been a lemon since day one. Started off by leaking water into the passenger cabin, dealer said that a drain plug was installed sideways. As a result of the water in the cabin, the main power wire to the amplifier corroded and shorted out. Dealer told me they would have to replace the radio...wrong, the wire on the passenger side floorboard had to be stripped and reconnected 2 mins to fix not $500 for a new radio. Next, Car started to intermittently overheated, with a loss of heating and cooling, dealer flushed the system and said the car is ok....not, took it to an independent shop who says that the head gasket is blown. How can I be added to the class action lawsuit..I have purchased my last GM vehicle.
