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.

Ignition switch will not start the car. It is in the off position. I am having a new switch installed. I do not understand why this car part is not on the recall list. All other 2003 Saturn are being recalled.

problem #1

  • 84,500 miles
Engine stalls after 10 minutes of driving. Won't start again for 2 or 3 hours only to run for 10 minutes and stall again. Sometimes engine will stall while idling. Sometimes the engine light with the wrench in it comes on and the vehicle starts to shift roughly. If I turn off the vehicle and start it again, this light goes off and the vehicle shifts normally.
