2002 gmc envoy fuel smell. Took to 2 different gm dealers before problem was found. The 2nd gm dealer found it to be the fuel pump module which was rusted and leaking gas. Gm would not stand behind this problem as she was the second owner. The problem is the way metal fuel pump module sits in the recessed portion middle of the plastic fuel tank invites moisture, rust , salt, corrosion etc. Replaced at our expense of $520.00 this is a design problem.
2002 GMC Envoy fuel system complaints
Page 3 of 3: complaints 41 to 56 of 56, newest first, as owners wrote them.
I have had a intermittent rumbling sound in the drivers compartment like the doors are not closed properly. I have checked doors closed but yet it still happens. Took back to dealership and they could not find a problem. The fuel gauge is reading incorrectly, at a half a tank of fuel the gas hand will intermittently move up or down. Also nov. 2006 a high pitch squeal from the front of vehicle while driving between 1 and 40 MPH.
Dt*: the contact stated while the vehicle was parked in the garage, a strong odor of gasoline was present. The vehicle was inspected by the dealer who determined the filler pipe neck, attached to the storage tank, leaked when the tank was filled with gasoline. The manufacturer was alerted. Updated 10/25/2006 -
Dt*: the contact stated the vehicle had a premature failure of the fuel tank assembly. The top of the gas tank assembly rusted out causing a fuel leak which increased the probability of a fire. Updated 9/15/2006 - the consumer saw the fuel leaking from the vehicle at a rate of 1-3 drops per second. The vehicle was taken to the dealer who determined that the fuel sending unit hardware was severely rusted and corroded. The entire assembly had to be replaced.
Dt: the contact stated while driving the engine check light illuminated. The vehicle was taken to a certified service dealer for diagnostic testing. Upon inspection the mechanic discovered a crack in the fuel tank in the filler pipe. Repairs were made to the vehicle at the contact's expense. This repair remedied the problem.*ak updated 1/11/2005. The fuel tank was replaced to correct the problem. The consumer requested a refund from the manufacturer because he feels that the filler neck should not have broken.
Was driving at 65 MPH on highway. Depressed accelerator and vehicle did not accelerate. Went to pull over and noticed there was no power steering or power brakes. Motor had stalled. The vehicle behind me nearly collided with me as I could not maintain speed and I had to swerve amongst traffic to get to break down lane. Tried to re-start in breakdown lane and incident repeated within 100 yds. Vehicle was towed to gmc dealer for service. Dealer had vehicle fail at least 3 times on roadway under same conditions over a period of 4 days. Dealer diagnosed failure of fuel pump module (pump, sensor, filter). Parts are being replaced today. After an internet search, I learned this is a "common issue" with this model vehicle. Should be a recall or preventive maintenance bulletin.
Vehicle has a crack in the fuel tank, and fuel is leaking at the filler neck where the neck attaches to the fuel tank. Owner contacted the manufacturer, who was not willing to assist the owner.
The check engine light was on. The dealer said that the fuel tank filler neck ruptured causing a leak. The fuel tank had to be replaced. There was no prior repair on the fuel tank or removal of the fuel tank. The owner has contacted the manufacturer to express that the design of fuel tank was bad for the environment. *sc. ....
A valve in the gas tank came loose causing a leak which activated the check engine light. *mr gas tank was replaced.
Gm advertises gas mileage of 16/22 miles per gallon. I am getting 10.5/12.5. I have taken the car back to the dealer to no avail. I have reported this to gm customer service to no avail. What next???.
Crack in gas tank on gmc envoy that was four months old.
When attempting to fill the fuel tank, gasoline will spill out the top of the tank (not the filler hose) and onto the ground. Rather than return up the hose and indicate to the pump that the tank is full, the gasoline goes everywhere. If you just add gas but do not fill the tank, this does not happen.
While waiting at a stop light fuel tank lost all it's fuel due to a hose separating from the tank.
The electrical computer memory for the exterior mirrors and the seat adjuster failed. This caused the seats for driver and passenger side not to be adjusted. Also the mirrors are not able to be adjusted. Driver has to continously adjust the miirrors in order to see. Dealer reset memory seats, reprogrammed mirror memory, and replaced left and right front seat modules. Did not remedy problem. Customer states that there is a fuel leak loss of 1/2 tank in 3 miles. Dealer repaired loose connection between main fuel line and the fuel tank.
We purchased new vehicle october 2001 and within 4 months began experiencing problems beginning with a noise within the steering wheel. Dealer technician replaced defective airbag module. The next month, my new envoy has been to the dealer 4 times for the same problem of 1) wind and/or whistling noise at speeds above 45mph, 2) "vibration" noise coming from transmission when vehicle reaches 3rd gear , 3) when vehicle has reached 3rd gear and previous noise begins, there is also a vibration felt in the acceleration pedal. On the first trip to dealer for these problems, technician only agreed with the wind noise. Discovered the front side mirrors were the cause. Replaced both mirrors---problem still exists, however, he can't hear them. Explained it was the nature of the vehicle. He also repaired the weatherstripping which had "fallen off" the right rear door. He advised that he did not hear any noise in the transmission area or in the gas pedal. We took to another dealer who had a technician test drive the vehicle and advised that there was both a noise in the area of transmission and a vibration in the gas pedal. Returned to the dealer who originally was doing repair work and had him ride with me. At this time, he heard the noise I was complaining about and advised that it was coming from the heat shield at the catalytic converter. Made an appointment for repairs, picked up the vehicle and later the same day, the noise returned. Took vehicle back, technician said he didn't hear any more noises. Waited 2 weeks, made another appointment to return vehicle for right rear door "rattling" , and "heat shield" noise which had become non stop. At this time, they replaced the weatherstripping on the door and again adjusted heat shield by making a "cushion" so that it would not vibrate against the exhaust manifold. This did not resolve the problem, as it still "vibrates" so as I can still feel stress through the gas pedal on the transmission when reaching speed.*
Gas gauge was 1/4 tank off, returned to dealer to fix problem after running out of gas. Dealer replaced float/sender. Returned to dealer one hour later after attempting to fill tank with fuel and fuel poured out of top of tank. Dealer then claimed the fuel tank was defective and distorted by the factory, ordered new tank, replaced same. All is working now.
