Fuel Pump problems of the 2003 GMC Envoy

The contact owns a 2003 GMC Envoy. The contact stated while driving approximately 30 mph, the check engine light would illuminate and the vehicle would stall on numerous occasions. The vehicle was taken to an independent mechanic who replaced the fuel pump. The repairs did not remedy the failure. The independent diagnosed that the fuel tank needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The VIN was unavailable. The approximate failure mileage was 137,000.

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.

I took my vehicle to the GMC dealership because of a distinct gas odor by the vehicle. I had previously received a cautionary letter from GMC that there could be a problem with the fuel pump involving pooling and pitting and extending the warranty to ten years to correct the defect. The inspection at the dealership stated that there was a "fuel leak from the top of the fuel tank area-fuel pump module leaking" the service advisor was sufficiently concerned to offer me a replacement vehicle to drive until the repair was made. He said that if I were to hit something and create a spark I could be in jeopardy. I was also concerned about a stray cigarette butt thrown out a window. He also gave me the customer assurance telephone number to call to file a claim. I did call the next morning and information was given and I was given a case number and told that the "district " would call me. When I received the call from that office she told me they would call me the following day. Ten minutes later she called back and said that gm would not offer any assistance. They obviously knew there was a potential problem or they would not have sent out warning letters. I believe it should have been a recall considering the potential hazards involved. I wonder how many people did not read the letter and subsequently had repairs made at their own expense so they never reported the problem. It was a costly repair and I feel they should have covered the expense. I count myself lucky that it is not my serviving family filing this complaint.

Fuel pump outlet tube was found corroded through after informing the local GMC dealer of gasoline odors when getting out of vehicle. This vehicle was purchased new in brandon, florida and has always remained in florida.

Fuel leak due to corrosion of the fuel pump/sender assembly.

Fuel pump outlet tube corroded through causing a release of fuel under pressure, which sprayed over the top of the gas tank and ran down both sides of the tank, I feel this could have easily caused a fire with any type of ignition source. This premature failure (5 years) cost over $1,000. 00.

Strong odor of gas coming from inside and outside of vehicle. Truck is currently in shop to replace fuel sensor and fill neck.

We smelled gas fumes and was losing fuel out of the top of gas tank. The fuel tank was removed and we found gas standing on top of the tank. We found the fuel pump had rusted and the metal lines coming out of the pum was leaking. We order a new pump and filter installed them and put fuel tank back in truck. Now it is ok no fumes or leaks.

Smelled fuel for several weeks. It gradually got worse, from just smelling it when I was outside the vehicle to smelling inside. Took to gm dealership in town. The dealership replaced the fuel sending unit. It had corroded to the point that when fuel was pumping it pumped fuel onto the top of the tank. $750. 00 was the bill.

Fuel pump module (fuel sending unit) corrodes and leaks fuel. And give faulty reading at the gas reading gauge. Not able to check if tank is empty.

2003 GMC Envoy xl fuel leak, my 2003 Envoy xl developed a smell of gas, became stronger as time went by. The vehicle was taken to a GMC dealer, who found that the fuel pump module was leaking because of corrosion. We had to have the fuel pump module replaced at a cost of $953. 10.

Gasoline odor outside and inside vehicle. Dealer found severe corrosion of fuel pump module, requiring replacement. They stated it was a common failure and had many prior examples.

I bought a 2003 Envoy xl 11 days before the incident. We went into a restaurant, came back out after eating and the car would not start. I was 150 miles away from home. The car had less than 1000 miles on it and had to be towed away. I had to leave the car, get a rental (which was paid for), and was told it was the fuel pump, which the dealer stated they had never had happen before. I told the dealer I was not comfortable with that car, but was told this was a unheard of problem.
