On October 17th, 2009, while pulling into the parking lot of mcdonald's, my van sudden accelerated as I entered the parking space, the motor was roaring. I would have been turning into my space, my foot would have been over the brake and I May have started to press the brake. When the vehicle surged forward, thinking my foot was on the gas, I immediately moved it further to the left and pressed the brake to the floor. I remember thinking this thing isn't slowing down one bit nor was it stopping, it felt possessed. It slammed into a heavy duty van, rocking it hard and doing considerable damage to our van. I did tell the officer at the scene that I must have had my foot on the gas, it was the only thing that made logical sense to me at the time. …
I was parked in the parking lot of my children's school. The car next to me needed to back out so I was moving my car forward a little to get out of their way. When I put the car in drive it started accelerating but my foot was on the brake. I turned the wheel to miss the block wall in front of me. The car had jumped the curb and was up in the landscape area. It was continuing to accelerate and I was pumping the brake and trying to not hit anything. I was trying to put it in neutral so that it would stop but by then the car was down in the other side of the parking lot and headed toward a three foot cliff. My youngest son was in the car and not buckled into his seat so I was panicking trying to get it to stop. I put it into park and it make a weird rattle noise and then stopped very suddenly. …

As I was accelerating on a city street, going uphill, the accelerator got stuck in the pedal-down position and the car started revving on its own. At the time, I was going about 10-15 MPH and the car accelerated to about 25mph before I was able to stop it. I quickly removed my foot from the accelerator and stepped on the brakes which slowed down the acceleration, but did not stop the revving or the acceleration. I tapped the accelerator with my foot which seemed to loosen the accelerator (it became unstuck) and stopped the revving of the engine. I pulled over to calm myself before driving on. This was the third time I have experienced this; the other two times happened on the freeway and was resolved the same way; by stepping down on the accelerator to make it unstuck. The action is very similar to the emergency-brake engage/disengage function on the Toyota Sienna.

On August 11, 2007, my family experienced a head on collision. We were driving a 2007 Toyota Sienna. My husband was driving and died at the scene. The investigation never found any reason for the cause of the accident. My husband crossed the center line while going round a slight curve. He was 47, poor weather was not issue. If the accelerator on the Sienna malfunctioned and did not respond, that could definitely have been a factor. Our van had less than 3000 miles on it. We purchased in May 11, 2007. The autopsy for my husband came back negative for any medical condition concern. Please investigate our accident report and be sure the safety and reliability of Sienna's is sound.
