At about 40,000 miles the fuel level sensor began to act erratically. At first, it would read empty occasionally and, on it's own, return to normal operation. After a few months, it began to read empty immediately after filling the fuel tank until about a eighth of a tank had been used. Eventually, it failed altogether and always reads empty. This condition confuses the engine computer causing the check engine light to light frequently.

Fuel level gauge will read full or partially full when fuel tank is actually empty. Or when fuel tank is full, the fuel gauge will still read empty and low fuel indicator light is on. Vehicle actually ran out of fuel when the fuel gauge read 1/4 tank. Vehicle stopped just out of a busy intersection, could have resulted in major accident.

The contact owns a 2006 GMC Envoy. The contact stated that the fuel gauge was defective. When she filled the fuel tank, the gauge would indicate that the tank was empty and the gas light would illuminate. The failure occurred everytime she filled the fuel tank. The vehicle had not been inspected or repaired. The manufacturer had not been notified. The current mileage was 76,721. The failure mileage was approximately 76,600.

Inaccurate and/or erratic fuel level indication, due to faulty fuel level sending unit, can result in vehicle running out of fuel with no warning to the driver ultimately resulting an unsafe driving condition with possible danger to the driver, passenger and surrounding vehicles and pedestrians.

I have a 2006 GMC Envoy with 51,000 miles on it. The fuel gauge would fluctuate between empty and full and now is stuck on empty. It has left my wife on the side of the road a few times because she had no idea how much fuel she had. One time in the middle of the night on a business trip. I don't want my wife stuck in the middle of nowhere because GM is to cheap to fix a very widespread problem on this issue. There are numerous tsb's on this issue on the internet concerning this issue with GM vehicles. They know the problem but when you contact them they say it isn't covered and will cost around $800 to fix. I S shouldn't have to pay for a fix to a very well known problem on a vehicle not that old. This is very much a safety issue when the car shuts down and you loose power steering in the middle of traffic, not to mention stuck in the middle of nowhere. Sooner or later it will cause a wreck if it hasn't already.

2006 GMC Envoy. Fill up the gas tank to full and the gas gauge reads as empty! you drive the truck for a few miles then the gauge will read normal. Then fill up again and reads empty. I have seen alot of people online with this same exact problem.. seems like every 2006 has this problem.

After filling gas tank the gauge suddenly dropped to empty and check engine light would come on. Gauge goes up and down eraticaly. Contacted GMC to which they would not help me. Search on line said there was a silent recall other owners said GM took care of problem up to 70,000 miles GM told me it was not a GM web site so they cannot do anything.. search internet and hundreds are having same problem...this is unsafe so I am filing a complaint as other have done before me......this is hazardous if you run out of gas everything shuts down and can cause and accident...there need to be a recall....

GMC Envoy 2006 fuel gauge reads incorrect fuel level beginning on 8 June 2010 (the vehicle had less fuel than the fuel gauge stated it had). Problem persists through the remainder of the month and into July. Beginning on 15 Aug 2010, fuel gauge would constantly change readings from E to F and vice versa for a few days immediately after each fill-up.

2006 GMC Envoy fuel gauge started to work erratically - would go to empty after car was filled up. Eventually stopped working altogether and the check engine light would cycle on and off. My wife drives this truck to work and could have a serious problem if she ran out of gas on the freeway. Luckily, the first time it ran out of gas was in a residential neighborhood. Took it into the shop and was told that they couldn't just replace the problem part (which is the fuel sensor) and need to replace the entire fuel pump at a cost of nearly $1100 updated IVOQ 08/24/10

In early 2010 my 2006 GMC Envoy began having issues with the fuel gauge immediately after a fill up. The gauge reads empty, the check engine light comes on then the gauge will rise and fall for the next 50 to 100 miles.

I'm a reservist in the military and it requires me to drive a distance to my base once a month. While driving to my duty location, I realized that my 2006 Envoy rwd was driving funny like it was about to stall. At the time, my fuel gauge read 1/2 tank. Thankfully I was approaching an exit and was able to get off and go to a gas station. I didn't know what the problem was especially since I thought I had gas. The gas station also had an auto shop. The mechanic couldn't even find anything wrong with my vehicle. He asked me if I was sure there was gas in it. I told him yes bc it read half a tank. We put about 5 gallons in the tank and the engine started right up. When I checked the fuel gauge again, it read it was empty. So I filled up the tank, got back in the car and started the engine but the fuel gauge still read empty even after I filled it up with gas. I was so frustrated because I had to be at drill and I had no idea what was going on. I just prayed that I made it there safely. I did..after the first day of drill was over, I started the engine and the fuel gauge read full but after driving 3 miles the check engine light appeared and the gauge went back to empty. I immediately drove to a GMC dealership where they checked the code for the engine light. The mechanic told me that the fuel sensor malfunctioned and that it was a common problem with Envoy. And since I was no longer under warranty, it would cost about $800 to repair. I called GMC customer service and they refused to cover it even after I went over my entire ordeal with them. I have not paid to repair the problem because I think GM should have pride in their products and replace this issue. The check engine light goes off after driving about 30 miles but my fuel gauge always reads empty even after I fill it up with gas. I have to fill up every other day for fear that I will run out of gas again and end up on the side of the road stranded. On drill weekends, I have to rent a car bc I can't rely on Envoy.

Gas hand failure.

2006 gmac Envoy. Upon filling gas tank to full the check engine light comes on and the fuel gauge shows empty. Gauge will fluxuate between empty and full for 10-20 miles. Then it will show full and the check engine light goes off. For the next couple of days it will swing back and forth between full and empty. Then it seems to work, although I'm not sure, it just does not swing quickly. I think this is a severe hazard...what if I was going 70 mph on the highway when and it shows 1/2 tank, but runs out of gas. Steering would be impaired and an accident could result.

Fuel system: The fuel gage has been going to empty after a fill up. After about 50 miles it would appear to work until more gas added. Now it is in total failure with an obd light intermittently. Obd light useless as no way to immediately determine if the gauge is the only problem. Have been using the trip odometer to approximate fuel remaining for more than 10K miles. Fear is that the associated fuel pump will fail as is all one part.

Incorrect fuel level reading may result in the vehicle running out of fuel without warning to the driver

- Hope, IN, USA

Check engine light accompanied by engine cut-off when cold weather since November 2009. Twice GMC dealership couldn't duplicate issue and no idea for check engine light. New development of fuel gauge failure each time of gas fill-up accompanied by fluctuating fuel level indicator. Clicking noise coming from gas pedal for 3 years with increasing frequency. Electrical system including gauges, speedometer, power steering noise, cruise control seem to be having issues. Dealership claims no recalls, but electrical issues appear to be common according to edmunds.com forums for GMC Envoy.

Driving to work at 5 am about 3/4 of mile from home, auto slowed, headlights deemed slightly, RPM's fell. Barely able to coast auto to side of road. Call for roadside assistance. While talking to agent I open door and smelled gasoline. Agent informed me to call fire department to ensure auto safe to move. Fire department arrived and said fuel was still dripping from auto, but they did spread something on fuel and waited until rollback removed auto. Auto was taken to GM dealer for repairs. When notified of repair completion I went to dealership. They told me I must have ran over something that pulled fuel line off, and that it was a 1 in a million event. I did not run over anything so I did not believe this statement. I research and found other have had same problem. I am worried because on the repair ticket it states customer states gas leaking as soon as the key turned was on, checked and found quick connect line pulled apart in front of fuel tank. Reconnected line all checks good at this time. I did not state fuel was leaking as soon as key was turned on. I was driving and almost unable to get auto to roadside. Very dangerous and if the only repair was to reconnect a line that had fallen off, it seems very likely to happen again.

It seems that my vehicles fuel sending unit is defective after only 40,000 miles and through further investigation I found there are many other owners of this line of vehicles that are experiencing this identical problem. I have been told that it will cost over $800 to repair this with no guarantee that it won't happen again. I think this problem should be recalled as most owners of this vehicle are quite upset that they have to pay out of pocket for this defective part to be replaced.

2006 GMC Envoy - fuel gauge shows empty regardless of how much fuel is in the tank. Since I have no idea how much fuel is remaining, I have run out of gas several times, including a couple on the interstate. The problem started around October of 2008, but costs almost $700 to fix, started at 37500 miles so it was just out of warranty, and there are hundreds of postings online about this problem stating it's a defect with the fuel pump.
