Other Fuel System Pump problems of the 2006 GMC Envoy

Gas sending unit/fuel pump lines rot out due to corrosion and spray gasoline all over the underside of vehicle. The vehicle might stall but often times it keeps running, all while spraying gasoline all over the place. This one does not even trip a check engine light while running in this condition. The only warning was the smell of gasoline- some people do not have a sense of smell, and this could have been very dangerous. This is a fire waiting to happen. This corrosion issue is known to gm, why is this not a safety recall? this let loose on my sister in-law while driving, it could have resulted in explosion or serious fire. Gm knows that these rot out prematurely due to poor materials and combined with road salt and environmental effects in snow states. This vehicle also suffers from the driver door switch for door locks and windows not always working, due to shorting out from water. . . Again a known issue with "some" units of this year, but this has not been recalled on this particular "unit" yet. Some of these have shorted out and caused fires- combined with the leaky gas sending units, this is a serious safety hazard. Do not park this vehicle in a garage- a fire waiting to happen. . . Come on- make gm take care of these problems before someone gets killed. This truck was at a dealer for the fuel leak, they told her it needs a sender unit and a bunch of other things that have failed on this poorly built truck, which include wheel bearings, abs sensors. Steering wheel sensor (? really) inop door locks, leaking fuel, water pump leaking, failing headlights- that work when they want, and a whole bunch of other repairs. This fuel and electrical issue(s) should be immediately recalled. This is affecting a lot of people who live in the northern states with snow and salt on the roadways.

Ignition switch failure at speed causing loss of power to fuel pump which ultimately meant loss of power to vehicle at freeway speeds. Was told by gm that there is no recall on this particular ignition switch at this time.

My fuel gauge stopped working over a year ago and I do not have the funds to repair it. The engine repair light is continuously lit and I have run out of gas on a major interstate. This as a major safety issue for a woman in today's society( kidnapping, rape, runover by another vehicle) I have learned to fill up every 3 days regardless of miles driven. I was driving on the interstate 3 days ago and the car just dies, with a full gas tank, 103 degree temperature and 2 children in the car. Try crossing major interstate traffic @ 80 miles an hour with 2 children, if this is not a safety issue I don't know what is. We had to tow the car and took it to a mechanic and he said the problem with the fuel gauge is located in the same mechanism as the fuel pump and caused the fuel pump to become so corroded that it stopped working. The need exists for an immediate safety recall, before there is a death or serious injury due to a mechanical default that has affected thousands of GMC Envoys and GMC refuses to stand behind their products because it is not a safety issue. It is a safety issue. . . . . .

Tl- the contact owns a 2006 GMC Envoy denali xl. The contact stated that the vehicle failed to accelerate over 40 mph. The contact also stated that the engine and the low fuel warning lights illuminated although the fuel level was at max. The vehicle was taken to the dealer where the contact was informed that the throttle body and fuel pump needed to be replaced. The failure mileage was 128,623 and the current mileage was 138,182. Mah.

Fuel gage in our 2006 GMC Envoy first became erratic then failed. Took vehicle to local reputable repair facility. They informed me that the sending unit on the fuel pump is known to fail in this vehicle. Had to replace fuel pump (I was told fuel pump and sending unit were one piece). The fuel gage began to to work again once fuel pump/sending unit were replaced. The total repair was expensive (parts and labor).
