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.

I filled the gas tank with gas, and when I was driving, I got this smell of gasoline. And when I got out to check the vehicle, I saw that the inlet check valve (icv) was fractured. And it was leaking gasoline.and 2 or 3 days after I had the check engine light on, with the code p0442.

The car starting leaking gas and I was afraid it would start a fire. I found out that the gas tank filler neck was cracked. Replacement cost was $1,220.68. Gmc said that this was not a recall item for my car but there were recalls for the same problem for the envoy xl.
I have a 03 envoy sxl that smelled like gas, the dealer stated there was a crack in the hose. I had that replaced and now it leaks gas going downhill. As I saw others are having the same issues and most if not all that has SUV's have children. If the same model part was recalled on the trailblazer why not envoy's? Gmc should recall all cars that has the model number to fix the problem before they go up in flames with our children.
I have 2003 gmc envoy, smell gas fumes when gas tank is half full, no gas is leaking on the ground. Will chevy cover some of these repairs? Seems like a number of owners have this same problem,.
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.
