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.

2002 Pontiac Bonneville Owner Comments

Car will re-start on its own after key is removed. After parking and shutting off the car, then removing the key and opening the driver's door to exit: If you accidentally press the upper part of the lock button on the door (the unlock function) instead of pressing the lower part of the lock button (the lock function), the car will re-start itself. It then cannot be turned off because the ignition switch is already in the off position. The only way to shut off the engine is to jiggle the shifter.
