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.

Bonneville 6-cyl

  • 50,000 miles
I was driving on the New York thruway and all of a sudden, my car shut off. I had to power steer, no power brakes, the fuel gauge read no fuel and the bells went off. I had to try to get to a safe place and restart my car. This has happened many more times. I can be going 25mph or 70mph; I can have the cruise on or off; I can have the heat or A/C on or off, it does not matter; in all cases, the engine shuts off when I am not expecting it.

On multiple occasions I have pulled to a dead stop at a light and during the idling time the engine shuts off and it will not start again. Very embarrassing set of trips to nearby grocer...

As I was driving along the engine, power steering, and brakes failed. I had to restart the car and hopefully resume driving so the car coming behind me did not crash into me. This has happened numerous times since including times while on I-95, I-81, rural mountainous roads (which resulted in my car rolling backwards), and city traffic. I have taken it in numerous times to my mechanic and he has not come up with a reason as to why this is happening. I am given no warning by my car that this is about to happen. The warning bell chimes and the car fails at the same time. This happened last evening and the car behind me had to swerve to avoid a crash. Please add my car to your recall or give me some kind of answer to take to my mechanic.
