All the electrical components go crazy. Speed-ometer works when it wants to just like the battery oil gas and temp gauge. The AC and heater have a mind of their own as well. Along with all the lights. Some times they work sometimes they dont

Defect investigations
Fuel pump module leaks gasoline
During the course of this ea investigation, odi observed that the majority of the complaints (88%) and warranty claims (94%) were reported for vehicles that are registered for use in the salt belt region of the us.this area includes 20 states in the northeast, mid atlantic and the midwest regions and the district of columbia.consumers in the salt belt region reported to odi that they could smell fuel vapors in their vehicles while driving.upon further examination of their vehicles, they discovered that fuel vapors were coming out of the top of the fuel tank. This condition is caused by corrosion of the return and sender lines of the fuel pump module.water and road salt collect on top of the fuel pump leading to small pinholes appearing on the fuel lines.fuel may leak and collect on top of the module and/or spill onto the ground.the data evaluated under this investigation reflect a relatively low frequency of occurrence that largely arises in salt belt states.gm has extended the warranty on the subject component to ten years or 120,000 miles.further use of agency resources does not appear to be warranted at this time; accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.for additional information select document search.
EA07009
Fuel tank leak
In june 2007, gm will expand its special policy to address fuel tank inlet check valve (icv) fractures on certain model year (my) trailblazer ext and gmc envoy xl vehicles.the expanded policy covers my 2002-2004 trailblazer ext, gmc envoy xl, and gmc envoy xuv vehicles and will extend for a period of 10 years or 150,000 miles (whichever comes first).gm will provide free repair of the fuel tank. It is sending letters to owners beginning in june of 2007.this action supersedes gm's previous 7 year/70,000 mile special policy for my 2002 trailblazer ext and envoy xl vehicles.the condition is most often reported as illumination of the service engine soon (ses) light.the vehicle's diagnostic system detects the presence of a fuel system pressure leak and illuminates the ses light.other owners report smelling gasoline fumes. The action taken by the manufacturer is sufficient to resolve the issues raised by this investigation.the closing of this investigation does not constitute a finding by the federal safety agency that no safety-related defect exists.the agency reserves the right to take further action if warranted by the circumstances.

What 2003 GMC Envoy XL 370 owners say
Most recent owner complaints, unedited.
Gmc is admitting to a faulty gas tank and only covers this up to 150,000 miles I bought the car after the 150,000 miles and now have gas leaking the tank was never fixed. Why does the mileage make a difference? This is a major safety issue that gmc should cover regardless of the mileage. Just because my gas tank did not leak as soon as other ones did means I should not be covered? A recall is a recall and they should be responsible for fixing the problem.
While filling up my vehicle with gas at samsclub, it began leaking continuously from the tank. We replaced the filler neck hose, but it turns out the gas tank has a crack at the top. When you walk by, you could smell the fumes.
This is all over the internet. Plastic gas tank leaks. Gmc does not care. I talked with them they ignore repair is $1,600.00 or more. People are fixing with glue? Gasoline spill from cracked plastic fuel tank.
Right rear door lock is broke will not shut or lock we were at the store and when we went back to the vehicle went to shut the door and the latch will not catch and shut the door.
The lift gate warning light malfunctioning says gate open and isn't light doesn't go off.
My wife was in the process of closing the rear hatch on our 2003 envoy xl (80,000 miles) after removing some articles from the back. She had moved the door about 1-2 inches downward using the molded handle on the bottom of the lift gate to close the door when the rear glass shattered over her head. Luckily she was not injured but was covered in safety glass. The glass was not damaged yesterday when I drove the vehicle and unloaded suitcases from the rear. Ambient temperature was about 70 degrees. I did notice that the rear brake light assembly is now angled upwards in the 'gate raised' position, even after closing the hatch. Also noticed the top, right side rubber grommet on the stamped bracket attaching the glass is very worn, allowing significant movement. I plan on taking the vehicle to a dealer to determine root cause if possible and will have the glass and all touch points replaced if possible. I have no confidence that this will not happen again if there is a design interference issue with the glass and the surrounding components that happens over time. There appear to be numerous cases on the automotive forums website regarding envoy xl rear hatch glass shattering for no apparent reason (some multiple occurrences). I am surprised more complaints have not been registered to the federal safety agency officially (only found one-10081011). It is only a matter of time before someone is seriously hurt. I have been a brake engineer for 10+ years and take safety very seriously.
