2003 GMC Envoy Owner Comments

problem #4

Dec 102007


  • 60,000 miles


The contact owns a 2003 GMC Envoy. The contact stated while driving at unknown speeds, the driver and passenger doors independently flew open. The contact was holding onto the door while driving until she was able to bring the vehicle to a stop. The dealer advised having a diagnostic performed on the vehicle to determine the cause of failure. In addition, when filling the fuel tank, the gasoline would spew back out of the filler tune and onto the contact. The vehicle was not repaired. The failure mileage was 60,000 and the current mileage was 180,000.

A cracking has occurred where the gasoline filler tube connects to the tank. That caused a vacuum leak, which caused the service engine soon light to illuminate. Dealership has diagnosed, and confirmed cracking and advised gasoline leaking could occur and recommends replacing tank. 1.vacuum leak renders gasoline tank emissions system inefficient. 2. if gasoline leak occurs, it is then a fire hazard. The dealership communicated to us, he has seen similar failures in that vehicle model (GMC Envoy).
