Brakes Failed problems of the 2009 Toyota Sienna

We were backing out of a parking place at the hot springs village walmart. The van accelerated on its own, then the brakes failed. No amount of pressure would stop the van. We stopped by hitting a parked car, doing some damage to it. We had the van towed to a body shop to have the exterior repaired. We were afraid to drive it. After being repaired, we had it towed to lander's in little rock where it was pronounced safe to drive. A few weeks later we sold it and bought a 2011 Toyota Sienna van. (an accident report will follow on the 2011 Toyota van VIN#[xxx]) information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

On July 29, 2010 at 5pm my wife parked her car in front my house on colesville road, facing the road approximately 23 feet from the sidewalk and 30 feet from the street. I had been asked by my wife to drive to the airport. We closed the doors, put on the seat belts, put my foot on the brakes and shifted the gear shaft to drive. Then I released the parking brake, the car start rolling slowly by the time I was moving my foot to the gasoline pedal gently, the car kept rolling , the gas pedal failed to accelerate the engine. I put my right foot on the brake, the brake failed completely. I tried to pump the break to stop the car without success. Suddenly, I found my self entering the busy street and cars rushing toward me. Trying to turn right and push the gasoline pedalto keep up with traffic, the car kept rolling slowly and the car never accelerated. "the gas pedal failed to accelerate as there was no gas pedal". Until I reached the right lane from the second lane, I shifted the transmission to neutral the car slowed and pushed the parking brake to stop. Then I changing transmission to the parking position. The whole traffic stopped, then I tried again to shift the transmission to drive and pushed the gas pedal which resumed its function and the brake too. When I entered colesville road the traffic was rushing, specially on the first lane where first lane car approaching my car, the driver started honking and swerved drastically around my car to the second and third lane to avoid hitting me. The following cars and the whole traffic stopped until I moved to the first lane and resumed moving. It was a horrible and scary experience with my wife and the two years granddaughter screaming and panicking. I called the dealer, the only advise I got was to get an appointment and look at the car. Tonight I took the car to the dealer.
