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.

2001 Pontiac Grand Prix Owner Comments

problem #2

Sep 022008

Grand Prix GT 3.8L

  • Automatic transmission
  • 86,000 miles


I had to replace the catalytic converter and I know a lot of people with cars that have twice as many miles and they have not had to replace the catalytic converter yet. It is a very expensive repair. I heard Toyota has a 7 year warranty on at least some of their converters.
