general problems of the 2004 Toyota Tundra

Vehicle began to accelerate down a steep hill and no matter what I tried to stop it, nothing happened, it just kept accelerating.

Vehicle began to accelerate down a steep hill and no matter what I tried to do to stop the vehicle nothing happened. It just kept accelerating. Lost control of vehicle, and was unable to negotiate the right hand turn. Vehicle slammed into a dirt embankment, then rolled over and reversed it's position. Consequently, I was trapped in a running vehicle with gasoline leaking and unable to shut off the engine. Had to wait 30n minutes for ems/fire rescue to arrive. Extrication took another 25-30 minutes. Transported to trauma center, york, PA.

Catalytic converter failed at 55,023 miles and was replaced under warranty. The same catalytic converter failed again at 110,000 miles and when I went to a dealer was told that it wasn't under warranty and that I would have to pay $1200. 00 for the part alone and labor would be extra. I also told the dealer that the high rear brake light housing was melting from the heat of the lights. They did nothing. The frame is rusting badly and is becoming a safety hazard. I called Toyota customer service and they said there was no recall for any of these items and there was nothing they could do. "adaptive equipment" is listed as a choice under "affected parts". How about explaining exactly what is the definition of "adaptive equipment"?.
