Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Takata recall March 9th 2016 9:30pm I was accelerating onto the highway from the onramp to about 70mph when the car kept accelerating after pressing the brake so I continued to press the brake but there was no release of acceleration so put the gear in neutral and I found room to pull to the right side and turn the engine off and put the vehicle in park. I gave it 15 seconds and re-started but it was still accelerating, I repeated this again with the same results. I left ithe engine off for a full minute and re-started to find it had reset. I then checked the floor mat and found it intacked and pinned to the floor pins.

The car accelerated on it's own, brakes were locked !!! I made a left turn after a stop sign and the car just took off on it's own - accelerating up to 50 miles per hour. I slammed on the brakes, but they were locked. I quickly put the car in neutral, it slowed the car down about 10-12 miles. To avoid cars in front of me - I then put the car in park. After an ugly noise and jerking of the did stop! there were no injuries or property damage. It was a horrific experience. The car was in full throttle! had it towed to a was still at full throttle when he looked at it a couple days later. He advised me to call Toyota. Toyota said it was out of warranty. I just want my car fixed,

I was coasting, barely moving when I heard the engine rev up and accelerate. My foot was not on the gas. Before I could apply brakes my car hit the house. I was about 2 feet from the house so there was not much time to react. This all took place in 1-2 seconds. I had turned into a driveway to park.

My laser cruise control became unreliable toward the end of 2013. I had used it on a daily basis for over 5 years and am very familiar with the way it should perform. When tracking a vehicle directly ahead of me on a straight and level road, the laser control should maintain a safe distance and a speed that is essentially identical to the "lead" vehicle. This has not been the case for the past 7 months. My car would often continue to maintain a speed that was faster than the "lead" car, as it was safely slowing down, and come so close that I would have to jam on my breaks. I brought it into the dealer, who insisted that the laser cruise control had been damaged in an accident (therefore my extended warranty would not apply) and I would have to make a claim on my car insurance. My insurance company as well as my repair shop could see no damage that would have caused the malfunction. Eventually my insurance company agreed to pay for the "repair". after the dealer repaired the car with a new laser control sensor the problem has continued, although not as often. I've had it back to the dealer several times and they insist it meets all specifications and is performing to manufacturer's specs, and that there is nothing more they can do for me. Corporate Toyota basically washes their hands of the incident by saying everything related to this matter is at the dealers discretion. Although I have not had an accident yet, this malfunctioning "safety" feature puts me at jeopardy. I fear for my life every time I use it. It would seem to me that others have had similar problems, and may have had significant accidents as a result. I hope you will look into this matter.

I was coasting to a stop at a red light with my foot on the brake and as I applied the brake harder to come to a complete stop the engine began to uncontrollably race and the car began to accelerate. I applied the brake as hard as I could, flipped the transmission into park and turned off the engine, missing the car in front by inches. I waited approximately 10-15 seconds, restarted the car with my foot on the brake and the transmission in park and the engine began to uncontrollably race again. I turned off the engine and waited approximately 2 minutes re-started the car and it started somewhat roughly but the unintended acceleration stopped and I was able to move the car off the road. When I parked the car I checked that the floor mat was firmly anchored and nowhere near the accelerator pedal and it was. Prior to the incident I was braking and the car was slowing appropriately so it doesn't seem that the accelerator pedal itself became stuck. I was able to drive the car safely to the dealer and notified Toyota.

Driver was pulling into a parking space when the car had unexpected, sudden acceleration and hit a concrete wall. Driver was wearing a seat belt; air bags deployed.

The front of the car is bashed in, hood is bent upward, radiator damaged and the front doors jammed. Men had to force the driver side door open to get the driver from the car. Toyota and the insurance company have been notified but neither have had time to examine the car.

My 2008 Avalon experienced unexpected acceleration twice, ,,once in 2008 and once in 2009...both times I had the cruise control on, which has a safety feature, a laser, which keeps you from getting too close to the car in front of car accelerated and ignored the safety laser. It slowed down immediately when I applied the brakes. The key is, the pedal was not stuck, I did not have to do anything with the floor mats, I did not have to keep applying the brakes, they worked as designed. Therefore it, in my opinion, was all electronic, as far as the acceleration malfunction.

2008 Toyota Avalon brake override. I just had all my Avalon recall fixes placed on my car, and the brake override fix does not work. I check my brake override to see how it operated before the fix, and after going to the dealership to get the repairs it still does the same thing. When the gas pedal is pressed, and speed is around 45mph step on the brakes while continuing to press on the gas, and you can hear the engine still trying to accelerate. The service advisor told me on the phone before going there that the brakes would override the gas pedal when the brake pedal is pressed. I still will not allow my pregnant wife, and 2 year old daughter ride in the car until a better fix is put into place.

2008 Toyota Avalon was recalled to replace a gas pedal. The car was taken in to the Toyota dealer for the said repair. It took 4 hours. A few days later the car was in reverse and was slowly backing out of a residential carport when it accelerated on its own and the car did about 3 loops around the garage area of the home causing damage to the car, benches, tree, bushes, lamp post, etc. This happened after the recalled defect was repaired. Owner of vehicle put in claim to her own insurance company, put in a call to the 800 Toyota number and had car towed to where she purchased the car. Everyone seems concerned, but only wants to repair the damage to the car rather than get to the root of the problem. We thought Toyota had the fix, but apparently not since accelerating and going out of control on an accelerated pace.
