Smelling of gas and leaking on ground, as I'm reading this is a common problem which is very serious. I really think GM needs to include this 2003 GMC Envoy as part of their recall as well. This has been going on for years it looks like and nothing has been recalled. Guess human life is not important.GM needs to recall this problem asap before someone gets hurt.

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.

Fuel leak coming from top of gas tank. I suspect it is the fuel pump module. Severe rust and limited visibility prevented me from identifying 100 percent. Talked to GM, they know of the problem but since it happened 14,000 miles beyond their extended special warranty for this, they will do nothing. Bad design is a bad design regardless of miles or years. Very dangerous having a leak this bad. Will fix myself when I come up with the money.

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 took my vehicle to the GMC dealership because of a distinct gas odor by the vehicle. I had previously received a cautionary letter from GMC that there could be a problem with the fuel pump involving pooling and pitting and extending the warranty to ten years to correct the defect. The inspection at the dealership stated that there was a "fuel leak from the top of the fuel tank area-fuel pump module leaking" the service advisor was sufficiently concerned to offer me a replacement vehicle to drive until the repair was made. He said that if I were to hit something and create a spark I could be in jeopardy. I was also concerned about a stray cigarette butt thrown out a window. He also gave me the customer assurance telephone number to call to file a claim. I did call the next morning and information was given and I was given a case number and told that the "district " would call me. When I received the call from that office she told me they would call me the following day. Ten minutes later she called back and said that GM would not offer any assistance. They obviously knew there was a potential problem or they would not have sent out warning letters. I believe it should have been a recall considering the potential hazards involved. I wonder how many people did not read the letter and subsequently had repairs made at their own expense so they never reported the problem. It was a costly repair and I feel they should have covered the expense. I count myself lucky that it is not my serviving family filing this complaint.

Envoy 6-cyl

  • 62,000 miles
Check engine light illuminated on instrument cluster. Diagnostics indicated a code po 442. This code is indicative of a fuel system leak in the evaporative emission system. Replaced gas cap. Problem not resolved. Filled vehicle with gasoline in October 2010 and several times since. Strong odor of gasoline is present. Each time fuel nozzle fails to shut off fuel from gasoline pump and gasoline is spilled on the ground near driver side rear door creating an environmental and major safety hazard. Vehicle never in accident or modified in any way. Vehicle has 62,000 miles. A courtesy General Motors repair program is in place for these vehicles if the long wheelbase models. Numerous occurrences in the short wheelbase models also. This is a known defect according to the GM dealer that services the vehicle, but they want over $1500 to replace the fuel tank and the tank unit which includes the fuel pump, gauge, and hose connections. There is no guarantee this will fix the diagnostic code that sets the check engine lamp, or the problem of gasoline leakage/spillage. The vehicle will not pass a state safety inspection and therefore is not allowed on the road. A forced recall should absolutely be made for these vehicles. At a cost of over $35,000 for this vehicle, and the hazards it represents, it is a total travesty that GM refuses to stand behind their product.

Strong smell of fuel coming from behind the driver side rear door. Check engine light on when code is checked... states small emission leak present. Upon doing a little web research find it to be caused by a leaking fuel tank. Appears to have a recall on tank for XL model which inturn is the same tank but the sle model is not covered under recall. If original recall was issued for safety concern why not comply for all models.

Vehicle is a 2003 GMC Envoy. Gas fumes were noticed coming from the rear of the vehicle. Also, check engine light came on. Took vehicle to GM dealer and was told that there was a crack in the plastic gas tank near the filler neck. Was told that GM has been having problems with this but no recalls or repair bulletins. Therefore, since vehicle was out of warranty I would have to pay $1350 for repairs. I see this as a safety issue. GM should be recalling these plastic gas tanks and replacing them at no cost to the customer as this is a safety issue. The vehicle could catch on fire! note: Vehicle was not in any traffic accidents or used for off-road driving or abused in any way. Gas tank should not have cracked. Also, I have seen many other similar complaints on the internet identical to this one so it is a common problem to the Envoy and trailblazer family.
