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.

2009 Toyota Yaris Owner Comments

problem #9

  • 16,000 miles


The contact owns a 2009 Toyota Yaris. While the contact was driving approximately 30 mph approaching a traffic stop, the brake pedal was engaged and the vehicle began to increase acceleration. The vehicle proceeded through the traffic signal. The brake pedal was applied repeatedly with force; however there was no reduction in the speed. The vehicle was driven off the road into a ditch in order to stop. The contact was able to resume with extreme caution. One year ago, the identical failure occurred. The vehicle had not been diagnosed or repaired. The manufacturer was notified of the unintended acceleration. The approximate failure mileage was 16,000.

I was driving at the regular speed limit and when the car in front of me was stopping to make a left hand turn. I stepped on my brake and the car would not stop. I was practically standing on the brake pedal and the car would not stop and I hit the car in front of me. The airbags deployed. I remember that a policeman told me to put on the emergency brake because the car was still sliding. I know I tried to stop and the car wouldn't stop. Based on their reports of Toyota's sticking accelerator, I thought this should be reported and investigated. I just came home last week. I broke 4 ribs in the accident and the car is totaled. I was in rehabilitation for 2 1/2 weeks. I would like to see this accident investigated. I have a clean driving record and I believe there may have been some type of mechanical issue that would not let me stop the car. The insurance salvage garage is holding the car for 60 days at our request so the car could be inspected.

She turned the vehicle off and called the dealer. The dealer stated that she needed to bring the vehicle in to have it diagnosed. There had been no repairs done to the vehicle. The failure mileage was 5000 and current mileage was 9062.

2009 Yaris has demonstrated unintended acceleration on two occasions with different drivers. It did respond after hard braking. This was after disengagement of cruise control.

This vehicle does not deactivate cruise control unless you stomp on the foot brake. Light application never does it.

Was traveling on constantine drive on my way to beach blvd in huntington beach. I was going approximately 15 mph, I had glanced down to look at my navigation system I noticed that I was close to a parked car and put on my brakes. I ended up striking the left tail light of a parked 2010 - blue - Ford element. The point of impact was my right front taillight. My car flipped over in one fell swoop and landed upside down. Eyewitnesses to the crash believe that a gust of wind caused the car to flip over. The police who arrived on the scene shortly thereafter could not find a justification for what had occurred at the low rate of speed that I was traveling. Even though the car flipped upside down the air bags did not deploy.
