Envoy 4WD 6-cyl

  • 140,000 miles
The fuel sensor on our 2006 GMC Envoy failed in September 2010. The low fuel light never goes off even when the vehicle has just been filled up the check engine light will come on. We must use our trip to keep track of mileage to let us know when it is time to fill up. This is a safety concern as you never know exactly how much gas is in the tank and because the gas mileage on this vehicle fluctuates from 15mpg-18mpg. When the check engine light comes on we are not sure if it is because of the fuel sensor or because of another problem. It seems that many GMC Envoy have this same problem and recently we read an article stating that GMC is looking into this problem. We wanted to make sure that our problems are reported as well.

Envoy 4WD 6-cyl

  • 39,000 miles
Problem with my gas gauge in just turned 40,000 mi. Add fuel light comes on even after fill up. Also gauge goes back and forth during operation of the car. When the gauge hits empty a bell goes off and the low fuel light goes on. Eventually the check engine light will also go on indicating there is an issue. Very concerned about breaking down and consider it a personal safety issue. Local GMC dealer has no clue there was a problem with gas gauges. Tried to ignore the problem but just got worse decided to get it fixed $900.

Gas gauge failed to work correctly. It would read empty after just filling up, sometimes it would appear to work and show there was more or less gas than there actually was. Ran out of gas a few times, due to failure of the gas gauge. Finally had to have it replaced (some sort of sensor), cost a few hundred dollars to replace.

The contact owns a 2006 GMC Envoy. The contact stated that the fuel gauge would provide inaccurate fuel level readings and would display that the fuel tank was full when in actuality, it was empty. The contact had the vehicle repaired in 2009 for the same failure. The VIN was unavailable. The failure mileage was unknown and the current mileage was 79,000.

I read in the newspaper that the NHTSA had opened an investigation concerning 2006 GMC Envoy gas gauge problems. I have the same problem as many others with the gauge fluctuating. This should be considered a safety issue since it could cause someone to be stranded. I have 53000 miles on my Envoy and this problem started about a month ago.

Envoy 6-cyl

  • miles
I own a 2006 Envoy. I have had several incidents of my vehicle shutting down while driving. Each time the road service indicated that my vehicle was out of fuel even though the fuel gauge read I had more than a sufficient amount. Even after they put fuel in my vehicle it wouldn't start without a boost. This happened twice when I was on the freeway which is very dangerous. Due to my financial situation I haven't been able to get this problem fixed.

Envoy 4WD 6-cyl

  • 70,000 miles
Faulty fuel gauge sensor, as well as a faulty instrument panel. The fuel gauge indicates there is no fuel when I have just filled up my 2006 GMC Envoy. Started with filling up my SUV and after I got gas, the gauge dropped to empty with the bell chiming low fuel. The check engine light stays on constantly even after having the car serviced. It goes off intermittently. Definitely dangerous as you do not know when you will run out of gas, especially with traveling with young children.

Fuel gage in our 2006 GMC Envoy first became erratic then failed. Took vehicle to local reputable repair facility. They informed me that the sending unit on the fuel pump is known to fail in this vehicle. Had to replace fuel pump (I was told fuel pump and sending unit were one piece). The fuel gage began to work again once fuel pump/sending unit were replaced. The total repair was expensive (parts and labor).

We own a 2006 GMC enovy. About two months ago, the fuel gauge started bouncing back and forth between empty and full. It didn't matter how much fuel was actually in the vehicle. The fuel gauge has become useless.

  • 60,000 miles
We have a 2006 GMC Envoy that has been experiencing fuel gauge issues. This has caused us to run out of fuel and now not be able to rely on the amount of fuel remaining. This shows both on the analog gauge and the mile remaining section of the SUVS dash display system. After filling the fuel tank the gauge goes to empty then jumps to full then drops down to empty and then the check engine light goes on. This issue is constant now and creates a distrust in the status of the vehicle..I have read many complaints online and no response to fix this persistent issue by GMC.

Fuel gauge has not worked for approximately 18-24 months; must use trip meter to determine number of miles traveled for calculation of next fill-up. Low fuel indicator light is always on. Engine indicator light appears upon each refill and eventually goes off after a number of miles are traveled. Current odometer reading: 75,314

After seeing that there is a probe into the GM vehicle fuel gauge problem, I'd like to share my concern as well. We purchased a 2006 GMC Envoy that had 45,000 on it in from a dealer in Ohio back in March 2009. Approximately September 2009, the fuel gauge was starting to act up, going from full to empty and empty to full at different times throughout the day. Some days it was fine and other days it was acting crazy. We took our vehicle into a dealership here in lansing and was told it was more than likely a fuel sensor problem and would be about $800-$900 to replace. Well, I couldn't afford to get it repaired at the time but my serviceman from crippen GMC said that they have had quite a few problems like mine. I knew there was a problem that was more than just mine as I have 2 relatives (brother-in-law and cousin) who also own the GMC Envoy yet both are different years and they have the very same problem. My brother-in-law paid to have his replaced and has since sold that vehicle and bought a newer model and it had the same issue, but the dealership noticed it before he picked it up and replaced the fuel sensor prior to him picking it up. My cousin and I however are currently using our mileage read to determine roughly how much fuel we actually have. When I asked mark, my serviceman at crippen if there was a recall on this he informed me that there was not. This has to be more widespread than reported as what are the odds of 3 relatives with the same vehicle type, but all are different model years having the same issue and if you count my brother-in-laws newer purchase, that would bring the total vehicles to four (4) just in our family. There definately has to be a product issue within the fuel sensoring unit

The contact owns a 2006 GMC Envoy. The contact stated that the gas gauge in her vehicle has malfunctioned by her filling her tank and the gauge not moving up once she starts the vehicle. The vehicle was inspected by a independent and they advised her that the fuel sensor needed to be replaced. The vehicle was not repaired. The failure mileage was approximately 83,000.

Envoy 4WD 6-cyl

  • 58,964 miles
We request that NHTSA open an investigation into the performance/reliability of the fuel level sensor on the 2006 GMC Envoy. Recently, we filled up the gas tank, started the car and the gauge went to full, we started to drive away, then the gauge dropped to empty. Now, the gauge continually fluctuates somewhere between empty and 1/4 to 1/2 full so we never know. The repair is extremely costly and our research shows there are numerous complaints about this problem and the failures seem to conveniently occur after the warranty has expired. Without a proper functioning gauge, we have to continually estimate the gas level and run the risk of serious accident/injury if our vehicle should stall and/or run out of gas.

2006 GMC Envoy. Fuel gauge stopped working after about 3 or 4 years. Reads empty even when the tank is full, just like the hundreds of other Envoy owners having the same problem.
