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.

2001 Pontiac aztec. Consumer states that he has some electrical safety issues with his vehicle. He has replaced the headlamp switch assembly, instrument control assembly, hva temperature control assembly, fuel pump module assembly and turn signal switch assembly. The lights that illuminated the assemblies burned out and the consumer was unable to see the instrument panel at night. Due to the sending unit malfunctioning, the fuel gauge would not register the amount of fuel remaining in the tank. Because the sending unit was a part of the fuel pump assembly, the entire unit required replacement. Also, while driving at night with the headlights on, when the consumer activated the turn signal, the high beam lights would come on. Upon turning the signal off, the high beams would also turn off.

problem #6

  • 945,000 miles
In early July, 2008, service engine light came on. Dealership replaced gas cap because diagnostic code indicated fuel vapors escaping. Service engine light came on next day. Returned to dealership, explanation was that the codes must have not been reset. Service engine light came on next day. Diagnostic codes indicated that fuel vapors are escaping. Crack @ fuel fill tube is diagnosed. I had received a letter from the manufacturer (GM) about this in January 2008. The letter indicated that repairs would be made if this problem made it necessary, but not to repair unless indicated (there was no recall). The part was ordered mid-August of 2008. I was told there were no parts in inventory, nationwide. After complaining to GM customer service, I was told that the part would ship on September 19th, 2008. As of October 9th, there is still no part, still no repair. The service engine light is still on, fuel vapors are still escaping from the vehicle. Is this safe"?"

I noticed fuel leaking from underneath the car onto the pavement. Upon closer observation I determined that the source of the leak was the joint were the fuel filler neck enters the fuel tank. This joint appears to be leaking through the plastic weld. My vehicle was not covered under the recall. But it is my intention to try and get GM to cover the cost of replacement.

Aztek 6-cyl

  • Automatic transmission
  • 80,000 miles
At about 80,000 miles my fuel gauge became unreliable. Once the fuel level would get below half a tank, the gauge needle would start bouncing around. It would go from half a tank to a full tank to an empty tank even setting off the fuel light. I dealt with this for about 3 months and then it quit working altogether. Now the needle never drops below 3/4 of a tank.

I bought a 2001 Pontiac Aztek in November of 2001. A few months ago the gas gauge started malfunctioning. The gauge says the tank is full when it's empty and vise versa. It goes up and down continually. My dad has a 2001 GM vehicle also and has the same problem.
