Avalanche 8-cyl

  • Automatic transmission
  • 30,000 miles


The contact owns a 2004 Chevrolet Avalanche 1500. The contact stated that fuel fumes emitted into the interior of the vehicle. The contact stated that the ABS warning lamp flashed randomly and the brake pedal became extremely difficult to depress to stop the vehicle. The seat belts failed to work properly to secure and retract. The vehicle was taken to a repair shop and the fuel lines were replaced; however, the failure recurred. The dealer replaced the cables associated with the tailgate. The vehicle was not included in NHTSA campaign numbers: 06E043000 (fuel system, gasoline), 05V163000 (seat belts), 05V043000 (service brakes, hydraulic) and 04V129000 (structure).

Avalanche 8-cyl

  • 48,000 miles
I started to notice a strong gas smell whenever I fully filled the gas tank. The odor would disappear after the needle moved off the full mark. Later investigation showed gas droplets coming down from the top of the fuel tank when it was full or near full. Subsequent examination by GM dealership revealed rusted out fuel module (pump/sender unit) locking ring and rust hole in top of fuel module. Examination required gas tank to be removed. Labor and fuel module replacement cost = $1000. Of more importance, the above allowed both fuel and gas fumes to exit the gas tank, creating a dangerous situation for vehicles parked in an enclosed area.

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 84,270 miles
Fuel tank vent valve has failed making it difficult to fill the tank with gasoline. When trying to fill the tank, the pump will continuously shut off. Opening the gas tank cap also releases quite a bit of "air". approximate cost to replace the vent valve/solenoid will be $210 which includes 2 hours of labor. Repair facility stated they were currently experiencing many requests to repair this same issue on GM vehicles.

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 9,000 miles
The contact stated vehicle would take very little fuel at a time and shut the pump off. The vehicle was taken to the dealership, and they replaced the fuel filter line. However, problem recurred. The vehicle was taken to the dealership, and they replaced the fuel tank. The vehicle would not take fuel at all, it leaked fuel on the ground. The vehicle is currently at the dealership again. When driving in excess of 55 mph the hood vibrated. The dealership has not been able to diagnose the problem.
