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 started experiencing a strong smell of gasoline while driving and when the vehicles was shut down. When I first noticed the odor I could not see any visible leaks under the vehicle, after about a week I started noticing drips of fuel under the vehicle. I crawled under the vehicle to find the leak and noticed a very fine spray of gasoline coming from the top of the tank. I then dropped the fuel tank and noticed that tube from the fuel pump was corroded to the point that it was spraying gasoline while under pressure. The fuel pump is located in a low point on the top of the tank which allows for road debris/salt and water to sit and erode these tubes on the top of the fuel pump. This is a very dangerous problem as all it would take is any form of ignition to cause an uncontrollable fire. Gm should be required to repair this under a mandated recall due to the severity of this problem.

The vehicle was not repaired. The manufacturer was notified of the failure. The VIN was unavailable. The approximate failure mileage was 137,000.
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.

My car is reaping with the smell of gas on the inside and outside of the car. I called gm customer care center about this problem being hazardous and all they offered was a $150 voucher available at the gmc dealership. I am confused as to why 2006/2007 models were recalled for this matter and the 2003 model was not recalled. I am afraid to drive this car because I believe it will explode!
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....
Some times when the brakes are applied the throttle also advances causing unwanted acceleration. Happens at low speeds. Have there been any factory recalls for this problem?

2003 gmc envoy. Consumer writes in regards to a defective fuel tank. *tgw according to the repair invoice, the fuel tank neck was cracked and leaking.
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.
Strong oder of fuel, ses light on, leak from neck or pump (unsure of exact location).
At start up, when car is cold, there is a strong fuel smell. Was told it was something in vapor recovery system.
