Will driving I came to a stop sign and proceeded to slow down but the car continued to rev a high rate and lunged forward into the four way cross before finally coming to a stop.

When starting to accelerate from a stop at a light, my toyota sienna suddenly bolted forward as if a boulder had been dropped on the accelerator. I braked as hard as I could, but was only able to keep the speed down to about 40-45 MPH. Eventually, it either it let up on its own, or I shifted into neutral and slowed, I am not sure which -- it happened so fast. I immediately got out of my car and looked to see if anything was on the accelerator, but there was nothing. I do have floor mats, but they are cut to avoid the pedals and in fact were not caught on the pedals. This is the one and only time it has happened. I reported it to toyota but they informed me that siennas do not have the part that is causing the sudden acceleration problem.

Tl*the contact owns a 2006 toyota sienna. The driver stated that while driving 10 MPH in an attempt to increase speed, the vehicle began to hesitate and surge. The dealer stated that there was nothing they could do to assist him since the failure was electrical which was also a normal function of the vehicle. The failure mileage was 10 and the current mileage was 75,000. The consumer stated when slowing down between 5- 10 MPH and then speeding back up again, the van would hesitate and then surge forward to the point of jerking the consumers neck. The vehicle would slow down once the accelerator was released. Also, the drivers side door was exhibiting a popping/scrapping noise when it was being opened or closed. The consumer took the vehicle to the dealer and was informed there was a recall regarding the thinness of metal which allowed the cracking of the metal where the door stop was attached to the door.

2006 toyota sienna le with bz package (vsa) - safety issue (electronics): vehicle stability control system (vsa) is unsafe during road slippery conditions if cruise control is used. The slippery condition could be rainy day or snowing or icy road conditions. The incident occurred several time. The first time I noticed the issue is around september of 2008. It was heavy rain, I was driving on a highway with normal speed. The van was set to cruise at 65 MPH. I ran over a small pot of water on the road. One of the tire probably slipped for a brief milli-second. The vsa control kicked in (I can see the vsa light flashes), the van was then running from side to side and the RPM suddenly jump up (violently). The van was difficult to control. I tap the brake to disengage the cruise control. Then the van went back to normal. 2nd incident, about december of 2008, I was driving on the highway with light snow. The van was cruising at 55 MPH. The van passed a slippery spot. The vsa kicked in and caused violent left and right movement of the van as well as sudden acceleration. The incident almost caused an accident. Since then, I stopped using cruise control on the rainy or snowy days. But if anyone out there with toyota minivan, I would like them to know it is a serious potential problem. I took my van to be checked out at the toyota dealership. They said could not find the problem and it is normal as is.

My 2006 toyota sienna is making this unintended acceleration even after I make a complete turn, or driving in a school zone. This is starting to get me worried since I am using this to transport my 5-year old daughter.

I have a 2006 toyota sienna, while driving I have noticed on numerous (5 or 6) that the car will surge forward without pressure on the gas. I am not on cruise control when this happen, it has happened on the freeway and when I am coming out of a turn. I am very concerned. I have also had battery problems with the vehicle. The car battery would die after a door was left open for 5 minutes. After numerous visits to the service center without being able to repeat the situation, and numerous bills since it was never a "problem" they finally were able to repeat it and fix the battery. Now this accelerator issue is much more scary for me. I have 3 children that I drive every day in the vehicle and I need to feel safe. The incident date I used below was the most recent however I first noticed this 2 years ago.
