I have a White 2005 Envoy with pin dots of rust all over the car on the metal and on the plastic parts as well, noticed this problem a couple of months after the purchase of the vehicle. I brought the car back to the dealer and they said it was rail dust and if they clayed the vehicle it would never come back, it came back. This processes went on about 4 times before they ended up get the districted service rep involved and he said it's environment and there is nothing they can do. I was just wondering if anyone else has had this problem because I am trying to gather information. I was told to take this case to CAMVAP its an outside arbitration for people not happy with the decisions of what they received from the dealer, service rep and after you called the 1-800 number.
Thanks Mike
