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.

2003 Pontiac Sunfire Owner Comments

problem #2

Nov 272009


  • 80,000 miles


I purchased the car in 2006 with everything on it stock. In 2009 the coil pack started misfiring causing the catalytic converter to go bad and also causing the rods bearings to spin.

Numerous of failures;air bag light came on and stayed on, clutch sticks to floor, car doesn't want to start. The turn signals and lights had gone out, it would take a couple of attempts to start the vehicle, there were times where the vehicle would start on it's own without the turn of the key, the vehicle used an extreme amount of gas, the dash would rattle, the engine would growl, the dash made a sound like the speaker was blown, there was a burning smell in the stereo and there was a thumping noise when turning the vehicle.
