Where the top of the nesk of the fuel tank meets the fuel pump it is broken where the 2 meet. Fuel vapors, as well as actual fuel leaking on the ground R both present. Stationary, as well as, in motion.

The contact owns a 2003 GMC Envoy. While driving approximately 5 mph, the brake pedal vibrated and hesitated to respond when depressed. In addition, the brake pedal felt abnormally soft when applied, which required a longer stopping distance. The failure became progressively worse. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 60,000.

problem #2

Envoy 6-cyl

  • miles
Driving at approx. 2:30 pm in intermittently rainy conditions- I suddenly found myself unable to control my vehicle and had trouble seeing my surroundings even though I had new rain-X wipers on. While I applied the brakes they did not work as effectively as they should. Additionally, after the first and second impact (multiple vehicles were involved)- no air bags deployed. I was the only person in the vehicle and still the drivers side air bag did not deploy. Resulted in two fatalities in another vehicle while I suffered a head injury, facial fractures that required surgery, and a broken collar bone from the seat belt that I could not afford the medical intervention required for repair.

Some times when the brakes are applied the throttle also advances causing unwanted acceleration. Happens at low speeds. Have there been any factory recalls for this problem?
