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.

With no apparent cause, the gas gauge on my 2006 GMC Envoy began fluctuating wildly. It first happened after I filled up with a full tank of gas- the gauge immediately went to empty and the warning light came on. Ever since, the gauge does not give accurate fuel readings- it will read full when empty, empty when full, and the needle will spike all over the place.. I consider it to be a significant safety concern- running out of gas in the middle of heavy traffic can cause serious accidents. Was diagnosed as a faulty fuel sensor in the gas tank and would cost $700 to replace.

With no apparent cause, the gas gauge on my 2006 GMC Envoy began fluctuating wildly. It first happened in March of 2011 after I filled up with a full tank of gas- the gauge immediately went to empty and the warning light came on. Ever since, the gauge does not give accurate fuel readings- it will read full when empty, empty when full, and the needle will spike all over the place. Just recently (may of 2011) the gauge stopped working all together. It now constantly reads empty. I consider it to be a significant safety concern- running out of gas in the middle of heavy traffic can cause serious accidents. I notified GM of the problem and just today, 6/3/11 was told "not enough information exists to indicate a problem or warrant a recall." They offered no assistance to help fix the issue, which was diagnosed as a faulty fuel sensor in the gas tank and would cost $600 to replace.

For about 2 years now, the gas gauge has had an issue on my 2006 Envoy XL. Incorrect readings and now complete failure. Unable to use gauge, had to depend on mileage readings. No repairs attempted, due to the cost involved.

The gas gauge will read empty right after the tank is filled. The gauge will then slowly go up, then go up and down randomly, resulting in never knowing how much gas is in the tank. Running out of gas is a real possibility at any time. The local Chevrolet dealer has diagnosed the problem as a defective sending unit, but no repair has been made yet.

Envoy XL

Two months ago after filling up my 2006 Envoy XL with gas, a previously normally functioning fuel gauge suddenly read empty and the audible warning kept sounding though I knew it had a full tank. The gauge would start to go up, but then when I would turn the vehicle off, it would read empty again. As I was driving, the gauge would fluctuate between empty and full no matter how much fuel was in the tank. A trip to the dealer showed that I had a faulty fuel sensor. They said that if I drove it around like that the vehicle could suddenly stall. I had to have the fuel sensor replaced at my own expense as it is out of warranty.

Faulty fuel tank sensor in my 2006 GMC Envoy. Filled my truck up only for the gas gauge to read empty. Then my check engine light came on! took it to the mechanic who told me the fuel tank sensor failed and he noted it a common problem in the Envoy. Its costing me $800 to fix this. I have done some web research and it indeed looks to be a common problem, I find this very disturbing. GM should recall all of them regardless of warranty or not?
