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.

Avalanche 8-cyl

  • 126,000 miles


As I was traveling on the highway at 70mph the engine sputtered and stopped running causing me to lose all power assist and to coast to the side of the highway. The vehicle was towed to my mechanic where it was discovered that the fuel line had rusted out and needed to be replaced at my expense.

The Avalanche is our tow vehicle (only) which is why it has so few miles for a 2002 model year vehicle. Normally it is towing a 9000 pound 28 foot toy hauler, but just by pure luck it was towing a single axle flat bed trailer with the cab for a 1935 Chevrolet pickup on it back from the body shop. I pulled into the driveway and tried to stop and there were no brakes. Tried to apply the parking brakes and the cable snapped. Stopped by driving up a hill into the grass. Took the Avalanche to the dealer where they told me the brake lines all had to be replaced and they were no longer available from the manufacturer. In the course of getting the brake lines out they found that the fuel lines were also leaking and had to be replaced. The total bill for repair was $2900, plus the vehicle was out of service for 6 weeks. Granted the vehicle is 12 years old, but I have a 1963 studebaker that still has solid brake and fuel lines. It is only by the grace of god that the Avalanche wasn't towing a 9000 pound 28 foot long trailer at 70 mph when the brakes failed. There was no warning light, no indication at all that there was a pending problem. Someone could have been killed. These vehicles need to be recalled, and I need to be reimbursed for the repairs.

The contact owns a 2002 Chevrolet Avalanche. The contact stated that a strong gasoline odor was inside the vehicle. The vehicle was taken to a local mechanic for inspection, who stated that the fuel lines were corroded and caused fuel to leak. The fuel lines were replaced. The manufacturer was made aware of the failure. The VIN was not available. The approximate failure and current mileage was 157,000. Updated 2/11/14 also, the brake lines were replaced as well.

Twice in a row when filling, gas backed up and spilled. I attributed this to a faulty pump. Later that evening while parked I discovered a fuel leak. I took it to a mechanic who discovered the fuel pump had rusted and corroded away. The next day I began my drive home from Florida to Chicago. I made it about 200 miles before we changed drivers, and discovered the truck had started leaking fuel again. Thankfully, we made it safely to a repair shop (a national company this time). They diagnosed it as the fuel tank, located a replacement tank, and I was under way. I did make it home to Chicago, smelling gas the wholeway, but not seeing a significant leak (probably due to the constant driving, I did keep checking) until I was almost home. I made it home, and took the car to a local shop. The diagnosed it as fuel lines, which had rusted and corroded. I picked up my truck last night, drove it to work today, then drove it right back to the mechanic, since it was leaking gas again. I have spent over $1500 so far in labor and parts, lost almost a full tank of gas with all the tank drops, and still do not have my truck back. Im pretty sure my, mechanic is ready to give up.

Fuel pump failed 3 times already. All door electrical solenoids/cable system failed-possible poor ventilation causing excessive condensation resulting in rusting of cables. Note: A friend with the same year model has exact problems and more. All costly and non-warranty items! could have been cause of accidents when fuel pumps failed but for the grace of god.

problem #4

Aug 212011


  • 137,000 miles
Vehicle stalls at high rate of speed, highway driving, truck hesitates and jerks, and comes to the near point of stalling, and low speeds, vehicle does the same, hesitates, and jerks, stalls, all systems fail. Starts back up upon shifting to neutral. Mechanic says it is the crankshaft position sensor on the 8.1 L 8100 series motor, the same motor that is in the 2001 model Silverado, Sierra, and Suburban that is the subject of a recall. Location is in the back of the motor making it near impossible to change out without major engine repair work, removing intake manifold and other complex things, to repair an apparent $60 part. Dangerous due to the fact that there is absolutely no indication that this is happening and happened on a vehicle that has been cared for completely. Also, dangerous due to the size of the vehicle and the near impossible task of steering it to a safe place with no power brakes or steering, especially at highway speeds. Mechanic says part it almost 100% plastic and can succumb to high and low variations in temperature and break down in composition. Which, it has done in this truck, again without no warning, and no apparent cost effective repair. It would appear that the recall should be extended to the 2002 model year as well as the same 8.1 L motor was installed in the Chevrolet Avalanche 2500 truck (by the way, the vehicle was built in 2001), which, other that the different body style has the same chassis and motor as the Suburban. Very dangerous for a woman, who cannot or does not have the strength to steer a 7,000 pound truck that completely stalled at a high rate of speed.
