Check engine light stays on. Had a diagnostic done and they said there's a gas leak coming from the gas tank fuel inlet valve. Common problem for the gmc envoy and correction involves replacing the whole fuel tank costing an average $1,400. Dangerous to drive if left untreated. Called gmc corporate and I didn't get any help. They said my envoy was not under any recalls. They should be held responsible for this defect.

What owners say
Fuel leaked everywhere had to replace the fuel pipe, hose and more pipes. Representatives at gmc adviced me that other vehicles with the same tank has recalls and my vehicle should be part of the recall! I called gmc multiple times and they opened and closed the case without any investigation as they promised! I paid $991.55 for something that should have been covered in a recall. I believe it is recall id 12v459000 just based on my internet searches. Gmc is denying me an investigation! Please help me one case # opened with gmc was [xxx] I don't know where I can get my $991.55 back and gmc keeps brushing me off and dismissing me. It is terrible!

- 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.
