My 2006 GMC Envoy fuel level gauge has started reading empty after filling with fuel. I have been using my odometer to keep track of miles since last fill up. It has been giving sporadic readings and can not be trusted. This could cause a dangerous situation if I was to run out of gas in traffic or on some lonely road in the country at night. GM is aware of this situation but is only offering to pay 50% at their exhorbinate service rates.

Fuel gauge is faulty as it provides inaccurate and random fuel level readings while driving.

The gas gauge has failed. It reads empty all the time. It is a very expensive repair, and the places willing to repair it are few and far between. The dealership is extremely expensive in this area. I understand many, if not most Envoy have this problem, and it can be dangerous, especially here in fairbanks, Alaska, where the temperature is easily -40 and sometimes colder. That is not a situation where running out of gas or a fuel situation occurring is something that a person is going to easily navigate during at least eight months out of the year.

Fuel gage stopped working. Fuel gage needle stayed on E after filling up. Stalled in left lane of interstate 80 in denville, New Jersey with my two daughters. Their ages at time of incident were eight and eleven. Almost rear-ended by tractor trailers. All three of would have been killed if the truck driver had not been alert and swerved to avoid us as I slowed and navigated to right shoulder.

The contact owns a 2006 GMC Envoy. The contact stated that the fuel gauge malfunctioned and the contact was unable to determine the exact amount of fuel in the vehicle. The vehicle was taken to the dealer for diagnostic testing and the dealer stated that the fuel gauge sensor needed to be replaced. The vehicle was not repaired. The failure mileage was 61,000.

The fuel gauge does not read correctly. This has caused the vehicle to run out of gas several times now in the middle of traffic due to the gauge telling me I had more fuel than I actually had.

My 2006 Envoy's fuel sensor guage abruptly quit working by originally, randomly indicating improper tank volume. At this point in time, the fuel guage is permanently stuck on empty and my fuel light stays on and the onboard computer constantly chimes and advises my fuel level is low. I just received a letter from GM stating they are aware of the problem and that provided my vehicle is displaying the signs of the problem (it is) I could take it to an authorized dealer for repairs and I would only be responsible for 50% of the repair bill. I find this absured! why should I pay to fix a known problem" why isn't this a full recall" I feel GM should pay for the entire bill to replace the fuel sensor and am requesting assistance.

Envoy 6-cyl

  • 45,700 miles
We have a 2006 GMC Envoy with 46,952 miles on it. One day in April 2011, with a 3/4 tank of gas, I was driving to work and the gas gauge dropped unexpectedly to empty. The bells started going off the messages came on the dash, the engine lights came on. This literally scared me to death. I thought the gas tank had ruptured and that all my gas had leaked out. I was terrified that the vehicle would come to an abrupt stop in the middle of the street. I made it to work and immediately looked under the vehicle to see if anything was leaking. There was nothing. I went into work and worried all day about how I was going to get to a gas station. When it was time for me to go home, I started the Envoy and the gas gauge read back to the 3/4 full tank. I started on my way home and all of a sudden the gauge dropped again. Ever since that day, every time we start the Envoy, the gauge will not read past "empty" and the warning bells/messages come on all the time. Sometimes, several times while I'm just driving to work. It came to the point where we do not drive the vehicle much anymore. With winter coming, I have to get this problem fixed as I need a dependable source of transportation. We have been told the problem is a fuel sensor in the gas tank. Whatever it is, we feel that GM should fix the problem for us and very soon. Would someone please respond as I am very unnerved about this whole situation. Thank you

On my 2006 GMC Envoy my gas tank was reading between 1/4 and a 1/2 tank of gas, so I stopped to fill up. Once I started the car back up the low fuel light was on along with the fuel gauge being on empty. After driving a few miles the engine light came on and stayed on. Once I was able to stop and turn the car off I did and the lights both stayed on. I began driving again on the highway and all of a sudden the gas tank started to rise up to 1/2 a tank to full. Then once off the highway it went back down to empty and then started going back up and down for the rest of the drive. I've never had an issue with this vehicle before, so when this happened I was very surprised.

I have a 2006 gmac Envoy - 49,000 miles - one month ago the gas gauge started moving on it's own, I would fill up and will show full as I am driving it will go all the way to empty and then slowly move to full and then back to 1/2 tank and the empty which makes the light and bell come on. When I turn off the car and restart it will then go back to full or stay on empty. This is a safety hazard I never know if I am running low on gas and will be standard in the middle of the road or is it about to stall out which could cause a wreck.

2006 GMC Envoy: Fuel tank sensor shows fuel then doesn't, bounces back & forth. I drive in the mountains and am now very paranoid that my car will run out of gas and leave me stranded on a mountain highway....very dangerous. Mechanic says error code is PO463. I am so afraid to drive my car alone now... so I stop gong down & then back up the hill just in case I can put in more gasoline. My car also has a drivers' side master control window that burned.... could have started a fire. When my mechanic took it apart, he showed me the burned areas, ... smells bad.

The gas gauge on my 2006 GMC Envoy always registers at "E." I have talked to GMC and there is no help with this situation though there have been hundreds of complaints on the same thing. When I called customer service they were rude to me and didn't give me a customer complaint number. I am having to gage my gas by keeping track of the mileage through the trip-ometer. Thank you for any assistance you can give me on this issue.

Hello, I want to file a complaint about my 2006 GMC Envoy. I've recently been having issues with my fuel gauge, when I fill up my gauge says I'm empty and then slowly creeps back up to full, however, it then fluctuates between full and empty and never gives an accurate reading. I feel this can cause a huge issue for people if they don't know their gauge isn't accurate.

A couple months ago my gas gauge started to act up. It was not registering the amount of gas in my fuel tank. I have already been stranded due to no gas and I just don't want it to happen at a critical time and cause and accident! I have a 2006 GMC Envoy. This issue needs to be addressed and handled.
