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.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

I have a 1998 Toyota Sienna recently the airbag light is on and the horn and cruise control are not working I wonder if this can be a safety recall for the life of the vehicle or do I just have to pay for the repair.

On August 25, 2010, I was taking my grandchildren to rainbow station daycare in our Toyota sports van Sienna xle, 1998. Warrenton Toyota dealer in Virginia performed a full 100,000-mile service on van on July 10, 2010. I turned into the parking lot of the day care at a speed of 5 mph with my foot on the brake. While I was about to park the car, there was unintended sudden acceleration of the car and car went from parking lot to sidewalk and began going towards the office of the daycare. I turned the steering to the right as far as I could in order to get away from the entrance of the daycare and the lobby (both have a glass wall) and was trying to get back to the parking lot the car would not stop. I tried to push the brake as hard as I could but the car would not stop instead it left car tire track marks on the sidewalk and the front lawn of the daycare. The car finally hit the brick wall and stopped. Fortunately the grandchildren were safe. My right hand wrist bone (radius) was broken. I had to undergo surgery. Our car was totaled and is beyond repair. Toyota is trying to find out he cause of accident.

The contact owns a 1998 Toyota Sienna. While attempting to start the vehicle, it suddenly accelerated and the engine continued running. The vehicle was taken to an authorized dealership where the contact was informed that the failure could not be duplicated. The current and failure mileages were approximately 100,000. The consumer stated when the vehicle was first started after sitting overnight, the engine would rev high even though the gear was in park. The consumer stated he then removed the key from the ignition. However, the vehicle would continue running. Updated 06/22/10.

What happened to the prius in California the same did happen to us back in 1999 with our Toyota Sienna van. My wife was driving on I-5 in Oregon. She pressed the gas pedal to overtake a car and then when she pressed the brake to slow down the brakes didn't work. She drove into the hwy median fence to stop the car. When we contacted Toyota, they didn't admit any fault with their car (the same what they are doing now) and told us it was our fault that we do not know how to use their brakes. We have several cars but we didn't have a problem with other cars. I didn't buy a Toyota after that crash but I am also worried who else the part supplier has been supplying parts to. I can be reached at [xxx]. information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My daughter was driving a Toyota Sienna, supervised by my wife. At a traffic light waiting to make a left turn, the van accelerated onto oncoming traffic causing a head-on collision. The van was totalled and the air bags deployed. No one was hurt but the oncoming car was also a Toyota, speeding through the traffic. I asked that both vehicles be inspected for sudden acceleration. However, the insurance company and police found it easier to blame the accident on my daughter than investigate the vehicles.
