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 Grand Prix Owner Comments

problem #3

Feb 152007

Grand Prix 6-cyl

  • Automatic transmission
  • 75,000 miles


Major window failure, only one window works, and too expensive to fix. My car has 70,000 miles and I have had fuel pump failure, total radiator failure, and two heat exchanger failures resulted in radiator fluid all over passenger side floor due too cheap crimps on heat exchanger which requires a hugh dash dismantle to fix, window failure, dash heat and A/C control failure. The car gets driven 11 miles a day to work and back and we have put $1000's into this piece of crap. Dealer and manufacturer could care less and want this website removed. No one is willing to do a thing. Will be switching brands asap to Dodge or Chrysler.
