general problems of the 2000 Toyota 4Runner

I was driving the truck to a body shop to fix the frame and body of the truck, as directed from Toyota. Which I was told from Toyota in portsmouth nh, to take it to a body shop to get it fixed. When driving the vehicle they car began to accelerate out of control, I had to pass several vehicles, the car was shaking as I had the breaks on the whole time. It was upwards of 80 miles an hour with out any control. My sister was following me, I also have proof from the body shop, as I barely made it there, I had to put on the emergency break to stop the car. Toyota customer service told me, probably driver error, not the case. When I left the truck with the body shop, they told me the frame and body of the truck were not repairable. I paid Toyota for tire rotation, oil change, and filters, to hear that I have to scrap the car. I still feel unsafe driving due to the truck accelerating out of control, and got no support from Toyota.

Vehicle was moving about 5 miles per hour into a parking spot while brake pedal was being pressed , all of a sudden there was an instant engine surge which propelled the vehicle over the parking lot media and crashed into the rear of another car.
