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 Chevrolet Avalanche Owner Comments

problem #1

Nov 032007

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 34,295 miles


At a regular service interval, the Chevrolet dealership informed me the front differential has a bad seal and needs to be replaced. This seems premature since the vehicle only has 34,000 miles on it. The dealer stated it was not a warranty repair due to time elapsed since purchased was over 36 months.
