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.

I own a 2008 Toyota Prius. On 12jul2008 I was returning home and driving on hwy 70 East, near goldsboro, nc. I was traveling at a speed of approx 55-60 mph. The vehicle was in cruise control. The traffic was getting heavy and I had to slow down. So I put on the brakes and the cruise control did not respond or disengage at that time. So I kept applying pressure on the brake pedal and pulled off of the roadway. When I lifted my foot off of the brake pedal the vehicle again wanted to accelerate. I had to turn the ignition system off and wait a short time. I re-started the vehicle and every seem to be ok. On 13jul09 I had the vehicle checked out by a Toyota of new bern, and they couldn't find anything wrong with the vehicle. They stated they would open a case on it and notify there company. I just wanted to write this notice in case it happens again to me or someone else.

I drive a 2008 Toyota Prius. As I was driving out of the gas station and stepped on the accelerator, the car continued going faster. The brake did not work, the only way the car stopped was by hitting another car. See also 10265332.

On a slight incline, with front wheels turned, car started normally then accelerated by itself and was difficult to stop with both feet on brake pedal. Acceleration was not suddenly fast but was increasing when I turned car into gravel drive leading up a hill. Car stopped with braking and was successfully turned off in the manner required by manual. Car restarted and no further problem was experienced.

  • 7,250 miles
The contact owns a 2008 Toyota Prius. While driving 75 mph with the cruise control activated, the contact accelerated past 80 mph to pass another vehicle. The vehicle would not slow down afterwards and accelerated past 90 mph. She depressed the brake pedal, but the cruise control would not disengage. The contact attempted to tap the brake pedal and shut off the cruise control manually, but was unsuccessful. She managed to pull to the shoulder of the road and shut off the engine. Upon restarting, the vehicle accelerated again without depressing the accelerator pedal. She attempted to reset the cruise control to 60 mph, but it would not respond. The contact waited 30 minutes before restarting the vehicle and it appeared to have moved from the locked position of acceleration. The failure and current mileages were less than 7,250.

I have a 2008 Toyota Prius with 10K miles on it. Several weeks ago while driving 65 on the highway, the cruise control kicked out and the car rapidly decelerated, almost like it was braking. I could not re-set the cruise control again until after stopping and restarting the car. The problem has again happened 3 more times in the past week. Auto dealership says they cannot do anything about it unless I bring it in and can recreate the problem. Very dangerous when cruise control kicks out and people are driving closely behind me.
