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 Avalanche Owner Comments

problem #3

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 60,100 miles

A D V E R T I S E M E N T S

2004 Chevrolet Avalanche designed without inline fuel filter, only a filter made into the fuel pump assembly inside the tank. According to GM and all data repair manuals, this filter is a non-serviceable item intended to last the life of the vehicle. At approximately 60,000 miles, vehicle mil indicator came on, diagnosed as misfire condition. Vehicle stuttered under both idle and acceleration. The dealer determined that sediment from the fuel tank had contaminated the fuel injectors and entire fuel system needed to be cleaned. Claim for repair under warranty was denied, even though non-serviceable lifetime part allowed contamination into the system. Very poorly designed fuel filtration system with the potential to cause stalling under all driving conditions.

Vehicle was purchased 1 year ago and continues to stall. It stalls at high speeds. Has taken it to the dealer, he says it is a fuel pump issue, they have replaced the fuel pump, and the problem is still there. Chevrolet says this effects vehicles above 5000 feet. And on hot days. Consumer lives at 6000 feet and vehicle does stall at high speeds.
