You'll have to either contact Toyota at their site, www.Consumeraffairs.com or www.nhtsa.dot.gov or phone 888-327-4236. An experienced mechanic will be able to relate some possible solutions. Uncontrolled acceleration with computer chip and processor controls isnot a new problem. I has occur with previous cars when you start up and shift it immediately into gear when rpms are still rising and dials adjusting. Electrons do funny things if you don't let the processors do their thing before providing new inputs.

Uncontrolled Rapid Acceleration (Lexus) by snevets23

On 1/31/07 while slowly reversing up a sloped driveway, my 1992 Lexus 400SC suddenly accelerated rapidly and uncontrollably. It felt as if I was in a rocket ship! Although I slammed on the brakes, I could not stop in time to avoid a car parked in the driveway. Luckily, there were no injuries (grandson was in car). This is my first accident in 42 years. While I hear that some conclude that I mistook the accelerator for the brake, I KNOW that's not true. My foot was on the accelerator to begin with since I was slowing giving the car gas to climb the incline. Weather conditions were clear, no obstacles on the floor, and I was wearing normal shoes... no boots or heels. This accident was NOT my fault, but I don't know how to prove this since the problem is intermittent. I have filed an incident report with both the police department and NHTSA and have sent a certified letter to Lexus in CA. However, there is strength in numbers and need to hear from others who have experienced this frightening experience.

Hi- I know exactly what you mean...Many people asked me the same questions re my Sienna van..I knew what I did and I refused to acknowledge anything else. Toyota sent out engineers to review the van...I'd make sure this happens..I had my van towed form the scene and refused to take it back until something was done. The engineers couldn't find anything..so I asked the 'male' managers, since the van is so 'safe' how would they like their wives to switch cars with me- so their family could drive around in the van- I kept telling them I didn't feel safe driving the van..Luckily they worked with me and I traded into a new Sienna van...
 
The police dept in Beverly Ma is currently investigating a horrific incident where a new cruiser (with documented uncontrollable acceleratin problems) took off on an officer and drove thru another car- killing the woman driver...
 
Demand attention to this problem...Good luck!

Thank you for your update and words of encourgement. I feel as though I'm just at the beginning of an uphill battle to prove my innocence and learn the truth. I plan to inquire of the Beverly, MA accident, but, by any chance, do you know the make of the cruiser involved? Thanks again!

 This happened to our 2006 Sienna yesterday--my wife was about to stop the car while parking it, suddenly it accelerated (very fast!) and knocked down a tree and scratched a couple of parked cars. The bumper was damaged and the right side dented. My wife is a careful driver (with two toddlers inside!) and she is very sure she did nothing wrong. I am very concerned to drive it again if the repair shop cannot find defect with the van..... Ben

I don't know the make of cruiser involved in the incident in Beverly- but when this happened to me I scanned the internet and found other Toyota cars with uncontrolled acceleration problems..I believe some lexus models and Camry's. The dealerships have their engineers check everything out- but they can't find anything..Its very frustrating, especially when you as the driver, know the car is accerlating out of your control.. Good luck..I hope it works out for you...

I know how frustrating that is...I was doing the smae thing in my Sienna van..I was pulling slowly into a parking space--except it was infront of a building- when the van uncontrollably accelerated and smashed into the building. Luckily I was without my children and only 3 feet infront of the building..But I was too scared to drive it again..and refused to take it from the dealership..I traded into a new car...

The body shop is repairing the damage and both insurance company and police were notified. They will have the dealership check the problem once damage is repair. However, I am worried that they may not find any problem thus my wife would have to drive the van in fear. Any good suggestion as to how to convince Toyota about the problem? Thanks a lot!

I had the same fear- and told the same to the dealership...I refused to take the car from the dealership..I told them I was too afraid to drive it again..the engineers/technicians checked out everyting and found nothing wrong..which seems to be typically the case..but I continually explained that I wouldn't feel safe driving it again....there was no other alternative than to trade into another car.which they did very easily for us..At the time no one else had complained about Sienna's..but now there are at tleast 3 other compliants since it happened to me..all on this Edmunds site..you have a better case that I did....Good Luck

I did not have the van towed to my dealership as it was further away. But I will make sure the dealer check it out. About the trade-in, did you give you a replacement new van for no charge?? Mine is only 3 month, 3000 miles. About the 3 other complaints-- could you specify where they are (did you mean the complaints in this forum you initiated that were different models?) Thanks.
