I purchased a 2004 GMC Envoy on 04-27-07 with 34, 125 miles on it. Since then I had a brake pad fall off while I was driving the vehicle. I replaced all four brakes, rotors, and tires. I have replace the instrument panel, secondary air pump (was filled with water), spare tire release mechanism, tie rod, wheel bearings, and most recently I had to replace the muffler and a section of the exhaust system. The undercarriage of my vehicle is so rusted it is causing parts to deteriorate and fall off. High possibility that I purchased a flood vehicle, but no one wants to acknowledge that possibility. The dealership won't help and GM told me all cars have rust. Unfortunately for me I was told by a local mechanic that if I drive my vehicle through another winter it will probably start falling apart. Does anyone know who can help me? I have placed complaints with BBB, Consumer Affairs, the Attorney General and now here.
