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

Avalanche Truck 5.0 Liter

  • Automatic transmission
  • 130,488 miles


Purchased 2003 Avalanche in 2007 and after a few months things started going. First smoke from under dashboard enough to choke on and the smell was wicked. A person stopped behind me, ran up and shut vehicle off and extinguished under dash. Towed vehicle to garage that had no computer tool so he looked under dash and pulled out a few burnt wires.

Two weeks later I tried playing and testing different wires to heater and bang it. I hit the right connection so it still works on high # 5 no lower numbers, but the worse thing was having smoke smell cleaned from vehicle $ 284.93 dollars later it was breathable again just needed to keep spraying smokeless deodorant.
