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.

2006 GMC Envoy fuel gauge began behaving erratically March 14, 2010. After refueling, gauge reads empty. Usually recovers after driving 10-25 miles. Difficult to know if refueling necessary. Vehicle warranty recently expired. It appears there are numerous similar complaints online and it is expensive ($700 - $800) to repair. We live in a rural area and often drive routes with 20 to 60 mile stretches without service stations. This is an ongoing problem. Please investigate faulty mechanism.

Gas gauge reads empty after filling, then slowly moves up after driving but will continue to lose pressure until it reads empty and the light is on, then the check engine light came on.

2006 GMC Envoy XL - fuel gauge reads empty at all times, even after filling tank. Safety concern due to not being able to accurately tell how much fuel is in tank. Could possibly run out of gas on road/highway posing threat of crash/injury.

My 2006 GMC Envoy started experiencing gas gauge problems. After a few calls and finding a website called, I see over three hundred complaints about this problem, many also at This is a very expensive fix and most can not afford this unless it is under warranty, which I find most are not.

The contact owns a 2006 GMC Envoy XL which was purchased January 2008. She stated that the fuel gauge continued to read empty even after she added fuel to the fuel tank. The low gas warning light remained illuminated. The vehicle was taken to the dealer who stated it would cost over $600 to repair it. There were no recalls pertaining to the failure. The current and failure mileages were under 53,705.

Gas gauge started malfunctioning at about 50,000 miles. It was fluctuating from empty to a normal read after fill up, now it just stays on empty even after filling the tank completely. Something that has to do with the sending unit and fuel sensor. Dealer wants about $800 to repair. After checking the internet, hundreds of people are complaining of the same thing.

Purchased vehicle in Feb 2008, gas gauge fluctuations began in June 2008. Now shows empty all the time, light and warning bells go off with each start and fill up. Ran out of gas on March 25th, was unable to fill tank completely and still showed empty.

The fuel gauge does not work in my 2006 GMC Envoy. One day I filled this vehicle up and the gas gauge remained on empty and for a month it would read normal sometimes, but now it stays on empty this has occurred within the last three months. I took this car to a GMC dealer and they said that the problem was the fuel gauge sensor, I have 52,000 miles on this vehicle and it's not under warranty, so this problem still remains.

The fuel gauge shows empty even when the tank is full. After the gauge has read empty for a while, the engine light then comes on. This is going to cost me $724 to get fixed, B/C the fuel pump needs replacing.

  • 44,000 miles
I own a 2006 GMC Envoy XL. We have 44000 miles on it. When we fill the gas the gauge reads full. By the time I pull off the lot the gauge starts to drop to empty. Never know how much gas is in the tank. Running out of gas in the middle of the night on the highway is a little scary for my wife. Not to mention a huge safety issue.

  • 33,702 miles
Had just filled the fuel tank and had driven about 5 miles when the check engine light came on and the fuel gauge had gone down to the empty mark setting off the low fuel alarm. Pulled off the road to check the gas cap, and it was installed, but loose. Discovered the O ring gasket was missing from cap. Drove another 10 miles and went to auto parts store and purchased a replacement cap. Engine check light extinguished, but fuel gauge sweeps back and forth, sometimes setting off low fuel alarm. Will call dealer on Monday to see if there is a sb for this. Almost out of warranty.
