3 times this year, when slowing to a stop with my foot on the brake, the car suddenly accelerated, requiring me to apply as much brake pedal pressure as I could, as well as shifting to neutral to stop the car. This has occurred once when coming up to a stop sign, and twice while pulling into a parking space. Both times when pulling into the parking space, I was barely able to stop in time, almost hitting a car in the space in front of me. After the last time this occurred (7/3/2020), the car was taken to st. Charles Toyota on 7/6, where they found nothing wrong with the vehicle. This started just this year; the vehicle has approx. 70,000 miles on it. We have owned the vehicle since new - it did not do this for the first 4. 5 years of service.

Unintended acceleration while reversing vehicle. Van went full throttle and sped up in reverse while backing up from my drive way at home.

Just before the vehicle comes to a full stop, there is unintended acceleration and I could see even the rpm(scale) to spike temporarily. This has been happening every time when outside temp is cold and vehicle is driven with cold or slightly above cold engine temperature. There is a risk of hitting another vehicle or meeting accident if misjudge my braking because of this problem. However it does it even on highway under normal temperature while I'm braking or slowing down.

My Sienna van sometimes responds very late to acceleration. This becomes a problem on highways specifically during the merging. Acceleration paddle has to be pressed very hard, for first few seconds there is no response from engine then latter it suddenly accelerates. This makes you miss judge the time required to merge on highways and can cause accidents. This has been happening since few months. I am providing tentative date below.

On June 6, 2019 at approximately 6 pm my vehicle experienced unintended acceleration. I was driving at 15 mph and it accelerated to 40-50 mph. Braking did not slow down the vehicle. I jumped the curb and hit three small trees. It came to a halt after undercarriage damage had been sustained. It was towed to cummings mobility where I purchased the vehicle. They could not determined what caused the unintended acceleration.

While stopped at a stop sign with my foot on the brake and waiting for traffic to clear, sudden unintended acceleration began. I lifted my foot off the brake for a split second and then braked hard. The engine returned to idle. This was the second time this happened, the first being three weeks earlier, shortly after having power sliding door recall work performed. I am convinced there is a defect in the electronic throttle control system. There is no other reasonable explanation. I took the car to my dealership and the dealer said a technician found all systems okay and no action was required.

The outside temperature was below 32 and it was close to 25 or so. When I was driving the car at 40 mph with engine temp still slightly above cold(not at optimal which is almost half way) and slowed down by using gentle brakes(not hard brakes).

On Monday, oct. 13, 2014, I was slowly backing out of my driveway when my 2005 Toyota Sienna van suddenly accelerated rapidly and uncontrollably. I tired to stop the van, but it sped backwards across the street in front of my house, ran over a curb, and crashed into a parked car. The car that my van struck pushed into another car which was also damaged. This was most frightening and upsetting, especially since I have learned that this type of malfunction has been reported many times to Toyota. My van was totaled, the second car may have been totaled and the third car will need at least a new door. A woman who was in the third car is claiming to have been injured.

Just notified of sudden acceleration. Hindsight - starting fall 2012 remote starter died,no warmup,my boyfriend and I experienced engine racing when van was cold multiple times,only way to stop it was hand control brake,foot brake was not enough. Planned to have checked but Dec. 1 2012 at the tanger outlet mall in canonsburg PA. I am paraplegic,my minivan is modified with foldout ramp- passenger side sliding door for wheelchair and then I transfer into the drivers seat. All the van handicapped parking spaces were filled but it was early so I parked in a regular space with an empty space next to it so I could get out. Few van accessible handicapped spaces is common so I used regular spots before as long as someone was with me who could back the van up far enough for the ramp to deploy. When my mother,my sister-in-law,my friend,and I returned to the vehicle a pickup truck was parked next to us. My sister-in-law got in the vehicle to back it up so the ramp had room to come out as she had done often. We stood behind the pickup truck waiting for her to back up. All of a sudden the vehicle flew backward so fast that before we could yell stop my vehicle had slammed into the SUV parked across the aisle so hard that it pushed the SUV into the car parked in front of it in the next row. My sister-in-law was completely shocked as were we, it was so fast it was almost like watching a cartoon. My sister-in-law kept saying "I don't know what happened", she thought all she did was put her foot on the brake and put it in gear. Not knowing about sudden acceleration in Sienna's all any of us could think was her foot had slipped even though she has been driving for 25 years without a similar incident she couldn't understand how it could happen, was sure it didn't. The police were called and a report filed. Because one of the welds from modification was broken my vehicle was totaled.

On mon 10/22/2012 at 11:15 am I experienced sudden uncontrolled acceleration driving my van. I was traveling on I-696e in detroit at a constant 70mph, then slowed to 45mph due to construction. As traffic cleared the construction, I pushed the accelerator pedal to pass a semi-truck. I felt the accelerator continue to depress, I completely pulled my foot off but the pedal did not come back nor did the vehicle slow down. Rather, it did just the opposite and continued to accelerate. I attempted to brake hard with no response--the vehicle did not slow down. Then I put the van in neutral to slow down the engine with no results, the van continued increasing 60+mph with no foot on accelerator. This is when I became extremely frightened. The vehicle was pulling from side to side. I looked down to see if there was any interference from the floor mat and none was seen. I tapped gas pedal - no response. Next I put van back in drive and braked --no response again. Then I downshifted to 4th, the engine did not slow, and further downshifted to 3rd gear. Finally, the engine responded and slowed. I used the gas pedal cautiously as I then shifted to 4th so that I could exit the freeway. I parked at my office & immediately called my husband first and explained what happened and I then immediately called the our Toyota suburban dealer. They told me to bring it in for inspection. I was still shaking when I brought the vehicle in and extremely upset. After two inspections, they stated sudden acceleration was caused by the floor mat. Although this seems reasonable, it does not explain why brakes failed to overcome the engine, and shifting to neutral failed to disengage the transmission. The vehicle scares me to death. I do not know what to do next. I consider myself a serious witness as a registered nurse (rn/bsn) with 20 yr manual driving. Ref Toyota case #[xxx] and #[xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

I was pulling forward from a red light, slowly accelerating. Someone cut me off, I swerved, and then accelerated into traffic. The car started accelerating on its own, from about 35 mph (where I pulled my foot off the accelerator pad to "hold" the speed but not continue accelerating) up to 55 mph--this happened very quickly, in a smattering of seconds. I remembered reading that you should just slam on the brake and hold it down hard, which I did. This did stop further acceleration, but it did not immediately slow the car. I was able to slow the car in about 10 seconds, though deceleration was very slow. When I finally returned to 35 mph, I did not attempt to accelerate again for about two miles. I stopped at another traffic light, and when I started forward from the light, I did not depress the accelerator pad with my typical force, accelerating at about half the speed I normally would, as I did not want to be taken by surprise by the unexpected sudden acceleration again. The problem did not further repeat itself this evening, but it was quite scary when it happened. I know it was not the floor mat under the pedal, as the floor mat has been cut away from the pedal area and was pulled very far back into the driver's seat area.

2005 Toyota Sienna. Attorney writes on behalf of clients in regards to a collision due to unintended acceleration as the consumer was slowly attempting to park the vehicle, it suddenly and unexpectedly accelerated out of control. The vehicle hit a pole directly ahead, went airborne and landed on top of a parked vehicle and rolled to the side. The consumers left hand fingers were crushed causing injuries.

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).

Geico claim number: 011597079-287 February 7, 2011 to whom it may concern: note, this is the second time I’m filing to update my address. On October 18, 2010 my 2009 Toyota Sienna dashboard vsc (variable skid control)/off track and check engine lights illuminated. I took my van in for service immediately. The dealership made repairs that were covered under warranty, and assured me that the van was safe to drive (a copy of the invoice from that service is attached for your reference). On November 24, 2010, the same vsc/off track and check engine lights illuminated again. When I returned to my local dealership for service, I was informed that due to the thanksgiving holiday, the service department did not have availability until November 30, 2010. Service advisor assured me that my vehicle was safe to drive, as long as I stayed in town, and wasn’t planning on taking the car on any long trips. However, I never got a chance to return my van to the dealership because on November 29, 2010 it started to make unusually loud noises and accelerated unexpectedly. Naturally, I attempted to stop by breaking, but the brakes were not functioning at all. I tried again and again to break, but to my disappointment the brake pedal did nothing, no matter how much I pumped it. Luckily, I was able to avoid hitting any pedestrians or cars by steering up the curb and into a lamppost. The van continued to accelerate uncontrollably until it finally came to rest on the steps of the county courthouse!.
