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.

1998 Pontiac Bonneville Owner Comments

problem #6

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.

Consumer bought the Bonneville in August, since then it has been in repair shop 7 times. The first four times were for transmission failure. They replaced the pressure control valve and throttle body. The remaining visits were for 4 fuel injection system failures, injector coil failures melted 4 spark plug wires. Also, water pump started leaking.

1998 pontaic Bonneville SE, standard V6 engine, while stopped with the brake engaged the engine will surge and leap forward. Car engine will quit while driving, causing loss of anti-lock brakes. Transmission sometimes shifts up and down without any reason, even at speed causing control problems. Suposedly related to the design of the intake manifold ( plastic cracks causing vacum problems and sometines loss of water). Also exterior paint started to peal off at 70.000 miles.
