During the turning of the steering wheel to the left at 5-10 mph, in making a left turn, clicks and clunking noise could be heard and felt through the steering wheel. At one point, I had to apply bigger turning force to the left as if I was overcoming some unusual resistance in the steering column, making the turn uneasy and non-smooth.

Our 2005 Toyota Sienna took off on us in rush hour traffic. Moving my foot to the brake and my husband shifting into neutral was the first thing we tried, we also tried park and reverse, and turning off the cruise control, none of which worked. The Toyota Sienna death trap continued to accelerate rapidly even though my foot was jammed on the brake (I didn't remove my foot from the brake for another 2 1/2 hrs until the tow truck pulled in front of us. By the way, when your vehicle is suddenly traveling much, much faster than anyone else's vehicle on the road, it's all you can do to not hit someone. Believe me, I was suddenly swerving in and out of the lanes and cutting everyone off. The only thing that stopped our Toyota death trap was pulling the key from the ignition, certainly not ideal in rush hour traffic. While this was going on, our son was in the backseat calling 911, while our daughter cried. We don't have a lawyer and Toyota won't fix our van. What are we supposed to do with it?

I had a sudden acceleration incident in my 2005 Toyota Sienna. I was making a slow U-turn in front of my home into a parking space by the curb on the far side of the street. The width of the street is such that even with the steering wheel turned fully to the left, the passenger tire rises up a driveway incline just before the car is 180 degrees around. As I usually do for this turn, I need to turn slightly more than 180 degrees, have the passenger tire come out of the driveway, then turn back to be parallel to the curb. I had slightly misjudged the turn this time, and realized that my passenger tire was going to have to drop an inch or two off the rising curb at the edge of the driveway. Because of this I am certain I had my foot on the brake pedal to keep my speed down. About 5 feet before the wheel was going to come off the curb, the car lurched forward, jumped the curb violently and fast, and continued my turn carrying me partly back into the street. I was very surprised, but brought the car to a stop quickly with the brake. The engine was no longer revving once I stopped. I estimate tat the acceleration lasted for not more than 2 seconds, possibly only 1 second. I reversed the car and then drove it forward into my intended parking space. After putting the shifter into P, I revved the engine and everything seemed fine. Fortunately, there was no accident and no damage I am aware of (although the passenger wheel did make a thump as it came over the curb).

I was pulling into a parking space in a shopping center parking lot when my 2005 Toyota Sienna suddenly accelerated and my van lurched forward into a tree. This has never happened before to me in this, or any other vehicle. As a result of the crash, my car was not drivable and had to be towed from the scene. I filed a police report, as well as a claim with my insurance carrier. I have since filed a complaint with Toyota, but have not yet heard from the inspector assigned to my case. Currently, the van is at a body shop awaiting inspection by the Toyota representative before anything else is done.

2005 Toyota Sienna had cruise control on. The vehicle began to 'shake' and the speedometer climbed to 80 mph then down to 60 mph. It didn't seem to actually be accelerating--it felt like the vehicle was fighting to not lose power. I deactivated the cruise control by touching the breaks. I pulled off the freeway, turned the motor off, waited and started again at a slower speed without the cruise control on. After a while the vehicle again began to 'buck and shake', the speedometer raced to 80 mph (though the car itself) did not seem to have rapid acceleration) then the speedometer dropped to 50 mph. Over the phone my husband advised I turn on the cruise control and turn it off again. I did and drove about 45 minutes home at speeds from 55-65 without another incident. I will take the car to a dealership tomorrow to check out. The vehicle has approx. 100,000 miles on it.

Will someone please call me asap. My Toyota Sienna suddenly accelerated last week in des moines, ia. Toyota is saying that Sienna's are not under recall. I was traveling with my husband and two children. The brakes could not stop the vehicle, nor did shifting it into neutral, park, or reverse. The only thing that worked was pulling the key from the ignition at about 75 miles per hour. The Toyota Sienna is a time bomb. The sudden acceleration of my Sienna has happened at least two other times. Toyota is claiming that the floor mats caused it, but my husband and I checked the floor mats, they were not the problem. Toyota wants us to come get the van but it's not safe. From NHTSA web site. Updated 05/24/10 updated 03/09/11 updated 06/23/14

We own a 2005 Toyota Sienna that has had an ongoing sudden acceleration problem since we bought the car new in 2005. The engine will suddenly accelerate when turning the car at lower speeds. This problem has been documented hundreds and hundreds of times, by Sienna owners on siennaclub.com (no longer in use) and on siennachat.com. The members on these sites have complained to Toyota for years about this problem. We have taken the car in for "reprogramming" but that did not fix the situation.

While driving from ca to va in may of 2009 I experienced an unintended acceleration while in cruise control. This occurred after I would slow down for traffic and then activate the resume control. This happened on several occasions during the trip East and on the return trip back to ca. The speeds with the unintended acceleration reached 95mph on the first occasion and stopped once I applied the brakes. After the first incident I was able to keep the acceleration from reaching more than 10 to 15 mph over the assigned cruise control speed.

The electronic throttle control system on my van is malfunctioning and it puts the vehicle in "fail safe" mode. The local Toyota dealer as well as Toyota customer service do not want to investigate this recurring problem for the dtc P0121. The dealers do not analyze the freeze frame data or investigate the problem beyond reading the code from obd II scanner. I had asked them for the electrical values for the throttle valve motor and the accelerator pedal but they have refused that information and want me to replace the throttle body by spending $1200. The first time this problem started when the vehicle had 50,000 miles and I replaced the throttle body from same year and model vehicle with 20,000 miles. Now after 10,000 miles same problem has started again and the dealer as well as Toyota want me to replace the throttle body. I feel that the throttle body or the gas pedal in conjunction with other electrical components are causing the dtc code and merely replacing the throttle body second time will not fix the problem unless the newer throttle bodies are without the problem original throttle bodies had. In that case I should not have to pay for the replacement part. It is important that the problem is investigated and identified before any parts are replaced. I also offered Toyota the original throttle body from the vehicle for testing / checking for the problem but they refused my offer. This sudden loss of drivebility due to the activation of "fail safe" mode is dangerous and could result in accident and / or fatality. Any help in this matter will be appreciated.
