The fuel inlet seal on the top of the fuel tank had separated causing a smell of fuel and allowing matter to enter the fuel tank from the top...possibly causing the premature failing of the fuel pump. We understand gmc has extended the warranty on the vehicle for this issue to 150,000 miles. Our vehicle had over 155,000 miles when the problem occured but we never received notification from gmc of the extended warranty. Had we received this notification we would have taken in the vehicle for an immediate repair. The fuel pump failed and we had to purchase a new fuel tank (as a result of the faulty top seal) and fuel pump...costing us almost $1,700. We have a copy of the repair bill but I am unable to scan and upload it here at this time... I am in the military and will be moving to korea in april, 2016

What owners say
Fuel pump outlet tube was found corroded through after informing the local gmc dealer of gasoline odors when getting out of vehicle. This vehicle was purchased new in brandon, florida and has always remained in florida.
Gas gauge bounced around intermittently for weeks regardless of fuel level. Now it just reads empty. Air compressor hasn't worked since last november. Fuel pump went out last night. Remote keyless entry has never worked. Check engine light is always on. What a lemon. Will never buy gmc ever again.
Tl* the contact owns a 2006 gmc envoy xl. The contact stated that after refueling the fuel tank, the fuel gauge would fluctuate and provide erroneous fuel level readings. The vehicle was inspected by an independent mechanic and they advised him to replace the fuel pump. The vehicle was repaired. The manufacturer was contacted and offered no assistance. The failure mileage was approximately 61,240. Updated 12/12/11*lj updated 01/18/12
After filling the vehicle tank with gasoline, I started the vehicle and the gas gage immediately went to empty and the alarm sounded. The gage recovered after the level dropped to about 1/3 and operated correctly for the rest of the tank. Then the gage became more erratic and has no indication of the amount in the tank. I understand that this has been a common issue with the 2006 envoy and is very expensive to repair as they must replace the fuel pump and sending unit in the tank.
Tl* the contact owns a 2006 gmc envoy. The contact stated the vehicle stalled due to lack of gasoline fuel despite that the fuel level gauge indicated that there was fuel in the vehicle. The contact stated that the needle would fluctuate back and forth between fuel levels. The contact believed there to be a problem with the fuel pump. The vehicle was not inspected or repaired. The failure and current mileage was 45,000. Updtated 2/17/11 *cn updated 02/23/11
2004 envoy xl VIN [xxx] started as fuel smell, now leaking in the area where fuel pump attach's to tank milage 126224. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).
The fuel gauge shows empty even when the tank is full. After the gauge has read empty for a while, the engine light then comes on. This is going to cost me 724.00 to get fixed, b/c the fuel pump needs replacing.
2004 envoy with approx.47,000 .had to replace fuel tank due to fracture around filler neck and replace oxygen sensor .was informed extended warranty on fuel tank modular reservoir assembly which contains the fuel pump did not include filler neck I had to pay 1'551.16 dollars for repair.
Fuel pump outlet tube corroded through causing a release of fuel under pressure, which sprayed over the top of the gas tank and ran down both sides of the tank, I feel this could have easily caused a fire with any type of ignition source. This premature failure (5 years) cost over $1,000.00.
