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 Chevrolet Avalanche Owner Comments

problem #2

Aug 302004


  • 21,000 miles


Intermittent at highway speeds all warning lights come on. All dash gages zero out and the engine is non responsive to additional throttle. After pulling over and cycling the ignition off and back on the gages will intermittently reset and work properly.this was reported to local Chevrolet dealer. They duplicated the problem in a test drive and stated it was because of a after market auto start security system. The company that installed the auto start system checked it out and found nothing wrong with the install or the auto start hardware. I had them remove the auto start hard ware, the problem manifested again. I took it back to the Chevrolet dealer. They diagnosed the problem as the ignition switch. Removed and replaced switch.
