Sudden maximum acceleration accompanied by brake failure, without warnings, occurred on my 2002 Toyota Tundra 4.7L V8 causing loss of control of the vehicle, which ended in a rollover crash, resulting in total loss of the vehicle and injury to me. While departing a 25 mph zone (sign read "END 25 SPEED LIMIT") on a relatively straight section of the road, I very gently accelerated from 20 mph to 30 mph. As soon as the vehicle reached 30 mph, sudden maximum acceleration occurred. Taking my foot off of the gas pedal, first I verified that the gas pedal was not stuck or blocked, but the gas pedal was in the fully up position. I then pressed the brake pedal very hard, but it was locked in the fully up position and the brakes would not engage. I then verified that nothing was blocking the brake pedal underneath it. At that point, around 3 to 4 seconds after the sudden acceleration began, I had entered the first turn of a 30 mph "S" turn at a high rate of speed, while acceleration continued at the vehicle's maximum acceleration rate beyond my control with the brakes not engaging. In order to avoid collision with a camper motor home and a small car following it, I went into the oncoming traffic lane at the second turn of the "S" turn. My truck fish tailed and struck a reflector marker on the left side of the road. To avoid going down a 50+ foot, nearly straight down drop on the left side of the road, I turned right. To avoid striking the motor home, I turned left, then right again t
