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. I looked down at my feet immediately to make sure that I was not accidentally pressing the gas but my foot was still on the brake. I was late to pick my children up from school thankfully, because 10 minutes earlier the parking lot would have been full of children. I towed my car into Toyota and they are looking at it but said that my vehicle is not part of the recall.

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.

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. In replaying the events in my mind, I was sure my foot was over the brake, and that I didn't press anything hard until after the vehicle accelerated, after I moved my foot further to the left. I have since amended my report with the officer at the scene and my insurance company. The front-end damage on the van has been repaired. On November 17th a technical specialist from Toyota went over the van. They released the van back to us without telling us anything. My past history will show I am a safe driver and I do not panic easily.

This memo was sent via email on the Toyota website over a week ago and have not received a response from them. I believe the issue is very serious and potentially life threatening. It is regards to a 2007 Toyota Sienna that I own. At least five times in the last 3 months I have experienced a very serious episode with my Sienna. While my foot is depressing the brake pedal and after coming to a full stop, the engine would begin to accelerate very rapidly. I need to push down very hard on the brake pedal in order not to lurch forward. I have been fortunate that I have not hit anything. What should I do. Because the problem only seems to occur randomly once in a while, a mechanic would not see anything wrong. Thank you jerry greenwald
