2003 GMC Envoy: check engine light

Filed Sep 30, 2020 · Fuel system · CA

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.

It started with engine misfiring causing engine to jolt which damaged #4 coil pack seal to failed allowing water intrusion. In 2008, the gmc mechanic replaced all six coils seals but in 2013-present p0440 engine code is a leak in the evaporative emission (evap). Loose fuel tank filler cap is the most common cause that triggers the p0440 code. I failed a few smog check spending hundreds of thousands of dollars yet my problem still existence. I've contacted the bureau of automotive repair because purrfect auto in fullerton,ca lied about fixing my car. The bar made purrfect auto replace the gas tank and gas cap yet the engine light is still on displaying code p0440. Its been 14 years and I'm still dealing with this problem.

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.

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.

I own a 2003 gmc envoy. Two years ago the speedometer started sticking. It now does not keep the speed at all. My RPM (when in park) will rev up to 2 or 3rpm, my gas gauge has now started to sometimes not show I have any gas, the check engine light is on almost all the time, my air conditioner will blow out the back vent and barely come out of the front vent when I have it up full blast. And to top it off my back brake lights constantly burn out.. I have read numerous forums where many people are having some of these same issues but no recall. I don't understand that at all. I definitely think these bad instrument panels call for a recall!! This is a safety issue. I eventually had to cut a hole in the plastic over the speedometer and before it quit completely working when we would go on vacation, we would have to pull over on busy highways every 20 minutes or so to set the speedometer back to zero so it wouldn't show me going 120mph. Of course I can't even do that now. I'm just amazed I haven't ended up with a ticket for my speed or my running or brake lights. We have taken the envoy in to the shop and they told us we would have to take the car in to a gm dealer. I have to take it back in this week to have air worked on and who knows how much that will cost. I don't believe I should be responsible to pay over $500 for parts and labor in a car that is clearly defective and should be recalled. Please help!!

My vehicle was making a jet like sound on start up and while driving and eventually the check engine light came on. It also was making a clicking sound from the electronic heating unit. I took it in to a certified gmc dealer and they said the clutch fan needed to be replaced (expensive repair). Could not tell where the clicking was coming from at the time (1/6/11 clicking will not stop - ended up being a door actuator). I did some research on these problem and they are very common in these vehicle. I called gmc customer service to make a complaint because at a little over 59000 miles these parts should not have gone bad. I wish gmc would consider a recall on this problem as well as other major things.
