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.

What owners say
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.
The gas gauge stays on empty when there is a full tank of gas. There rear windshield wiper comes on by itself. The radio plays like it is in a tin box. Every so often it will play normal. But most of the time it doesn't. This happens when it is moving or in park.
Fuel light stays on constantly & fuel gauge always showing empty when vehicle running in motion or stationary
Low beam headlights fail intermittently while vehicle is in operation. Vin not eligible for recall under current headlight probe gauges have failed starting with fuel gauge.
Tl* the contact owns a 2004 gmc envoy. Upon entering and starting the vehicle, the speedometer displayed a reading of 45 to 90 MPH and the tachometer displayed a reading of 1 1/2 rpms. The contact stated that the failure occurred mostly during the winter months. The contact also stated that the battery charging alert displayed incorrectly as well as the fuel gauge. While driving various speeds, the speedometer displayed incorrectly. The vehicle was taken to an independent mechanic where it was diagnosed that malfunctioning magnets and the cluster needed to be replaced. The contact stated that the speedometer was replaced, but the failure persisted. The vehicle was taken back to the independent mechanic who informed the contact that the circuit board and instrument panel needed replacement. A dealer was not contacted. The manufacturer was made aware of the failures and did not assist. The failure mileage was approximately 9,000.
At fill up gas gauge goes to full and stays there for around 20 miles, then drops to empty and stays there. This is an ongoing problem for several weeks now. Apparently this is a known issue, with the vehicle.
Speedometer flucuates past 120 and sometimes drops past 0 while driving. The fuel gauge will show full even when it's not.
My gas gauge stopped showing how much gas is in the tank. Even when it is full, it still shows that it is empty.

- What is wrong
- On certain sport utility vehicles, a fuel filter fitting can become disconnected. If this were to occur while attempting to start the engine, a no-start condition would result and fuel would be pumped out the fuel filter onto the ground.
- Risk
- If the fitting becomes disconnected while the vehicle is in motion, the engine would stop due to inadequate fuel supply and cause a loss of power steering assist. If an ignition source were present, fuel leakage from a disconnected fuel filter fitting could result in a fire.
- Remedy
- Dealers will replace the fuel filter quick connect retainers. Owner notification began september 20, 2002. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact chevrolet at 1‑800‑222‑1020.
