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.

2004 Chevrolet Impala Owner Comments

problem #1

Jan 072008


  • 13,000 miles


The contact owns a 2004 Chevrolet Impala. While driving approximately 15 mph, all of the instrument panel gauges stopped working. Prior to the failure, the heater unit shut off without warning. In addition, after several attempts to start the vehicle, it finally started and drove roughly. The vehicle was taken to an independent mechanic and it was discovered that the failures were related to the security system in the control panel. The vehicle was repaired for the malfunctions. Recently, the driver message center and horn were not operating, and the transmission was not running properly. The vehicle has not been repaired. The failure mileage was 13,000 and current mileage was 27,000.
