2003 GMC Envoy: wrong fuel gauge reading

Filed Jul 6, 2025 · Electrical · MI

The car's gas gauge and fuel range indicator are problematic. The fuel gauge quickly drops from a higher reading, like 3/4 full, to empty. After this, the gauge and the fuel range both fluctuate while driving, making it impossible to determine the fuel level.

Bulletin no.:14423 date: november 2015 part number: 15077622 tank, fuel (18.7 gal.) the icv is located above the full fuel level. A fractured icv could allow fuel vapors to pass through and droplets of fuel to accumulate on the side of the fuel tank as it passes over the fracture during refueling. If the icv fractures, the vehicle's service engine soon (ses) light may illuminate, and you may notice a fuel odor and/or a few drops of fuel on the ground when refueling the vehicle. This has happen to me and now my tank needs to be replaced. This is a known issue with gmc envoy regardless of year or how long they are in service. The company needs to be held accountable for poor quality of parts especially when it is a safety concern and hazard with fuel odor coming into the cab of the vehicle and spilling out when going up a hill. Being told to only fill my gas tank up half to three quarters full due to that part being broken is the wrong answer. In motion when I smell gas and then notice it when I fill the vehicle up and it started pouring out.

2 years ago the maintenance required light has been on, when checked by 2-3 mechanics they said it could be the gas cap. That didn't remedy the situation, the light stayed on, then recently the fuel gauge started dropping to empty after a little less than half a tank was used. Then filling the gas tank caused it to overflow if you fill it to full. As of today the car when shifted into reverse, something came loose inside the shifter, now it is stuck in neutral.

Gas gauge is not working. Amount of gas in tank unknown due to this error, not only making driving unsafe, it is also a major inconvenience. We have replaced fuel filter in gas tank and problem still persists. Now our mechanic has suggested a new imstrument cluster.....$500 later will it be fixed?' all the while gmc knows of this problem.

In 2010 after filling my gas tank in my very well kept/serviced 2003 gmc envoy I began driving home and noticed that my gas gauge wasn't working. The tank was full but the fuel gauge read below the empty. After tapping on the instrument panel, restarting the vehicle, checking fuses, etc nothing worked so I took it to the shop and was advised that gmc has known about this problem for quite some time and won't do anything about it. Either the fuel sending unit or the sensor is bad and must be replaced at a cost $500 - $600. After doing some research I see that this is quite the problem amongst gmc vehicle owners and confirmed that gmc will do nothing about it... Now my fuel gauge reads differently at every time the vehicle is started; but it never reads correctly.... This should be investigated and gmc should step up and take responsibility for their inferior parts....

I was driving down the road and fist off, my speedometer went crazy. Then my fuel gauge went all the way to full, then to empty. Then it wouldn't work at all. There was plenty of gas in the tank too, I took to a mechanic and he replaced thermostat, but it didn't fix the problem. I'm still having the problem and heard there is a recall on the 2005-2007, and it appears I'm having the same problem on this 2003 that they are having now with the newer ones and the 2003 should be included in a recall. Please evaluate. I only have 107k miles on the truck. I was told, a recall could cover up to 120k miles, so I still have some way to go before I should not be included in the recall. My service engine light is staying on too, although it's been checked numerous times and it's always something to do with the fuel system and too expensive to get fixed. Now I am having major problems because of it.

My gas gauge has been inaccurately giving the proper fuel level. Today I noticed the gauge is now stuck way past the "full" level" and does not move.

I own a 2003 gmc envoy. Two years ago the speedometer started sticking. It now does not keep the speed at all. My RPM (when in park) will rev up to 2 or 3rpm, my gas gauge has now started to sometimes not show I have any gas, the check engine light is on almost all the time, my air conditioner will blow out the back vent and barely come out of the front vent when I have it up full blast. And to top it off my back brake lights constantly burn out.. I have read numerous forums where many people are having some of these same issues but no recall. I don't understand that at all. I definitely think these bad instrument panels call for a recall!! This is a safety issue. I eventually had to cut a hole in the plastic over the speedometer and before it quit completely working when we would go on vacation, we would have to pull over on busy highways every 20 minutes or so to set the speedometer back to zero so it wouldn't show me going 120mph. Of course I can't even do that now. I'm just amazed I haven't ended up with a ticket for my speed or my running or brake lights. We have taken the envoy in to the shop and they told us we would have to take the car in to a gm dealer. I have to take it back in this week to have air worked on and who knows how much that will cost. I don't believe I should be responsible to pay over $500 for parts and labor in a car that is clearly defective and should be recalled. Please help!!

Instrument panel cluster is failing. My speedometer has totally quit working.my gas gauge is starting to fail also. I checked on the internet and found that gmc has admitted the stepping motors are defective, on the instrument panel cluster gauges for my 2003 gmc envoy. A class lawsuit has been filed, according to the internet .according to the internet,this is a common problem for 2003-2007 gmc's. The cost of the repair is appx. $800.00. I cannot afford this repair. I am forced to drive without knowing my correct speed, due to the speedometer not working. Soon I will not know ....how much gas I have in my gmc. According to the internet my other gauges will soon fail. I purchased my gmc brand new for $38,000. I feel my gmc envoy is unsafe, due to the reasons I have just listed. I feel gmc should pay for this repair as, it is unsafe for me to operate the gmc like this. I would like to be included in the class action lawsuit. The failure is constant...no speedometer. This could cause my to drive over the legal speed limit with out my knowledge, which is unsafe. I have done nothing to correct the failure as yet. At this time I cannot afford the cost of the repair.
