Gas gauge malfunctions after filling vehicle due to repeated, documented manufacturers defect in gas tank fuel sensor, possibily leading to a complete failure of indication system.
I own a 2006 Envoy denali and last may 2010 I was driving down the a busy highway around 55 miles an hour and the truck just lost all power and completly shutdown. It took aleast three trys before I could get it started again. I was so scared that a tracker trailor would hit me from behind. It didnt do agin for a week , and then it happend again. I brought the truck to the shop and the throttle body was replaced at about 65,000 miles. Now its a year later and I again was driving on the highway and the truck engine light came on and all power was lost. I put my hazards on but could only get the truck to about 15 miles an hour so that I could get out of harms way. I called GMC to make an complaint as it is very rare to have to replace a throttle body every year. I take care of my truck and see no reason why it happning other than GMC defect. GMC did not help me and just said there were no recalls and that it was normal wear and tear. I no this to be untrue and I am very dissapointed with GMC and will never buy the product again. I have had nothing but issues with this truck, and after looking into it there are several other Envoy owners that are having the same problems as I am. I dont drive on the highway if I can help it at all, getting stuck in the middle lane with a truck that won't move is way to scary. GMC should have to make it right and recall the truck and figure out why the throttle body fails.
I bought a use 2006 GMC Envoy denali with 69,000 mile in June 2010, by July I was replacing the air shocks on the right side of the vechicle. On about 7/28/2011 on the beltway where the speed limit is 65 I was in the far left lane approaching a left hand exit when my car staled, I had run out of gas with no indication. I wait over a hour for someone to come put gas in my truck at about 100 degree tempature. I later ran out of gas on a back road coming to my house at night. Again no indicator light came on to let me know I was low on gas. Not the gas gauge floats between fuel and empty contionusly. This was a very dangeous and scary situation both times. I flasher were on the whole time and I had to change the battery. Now the air will not come out of the vents only the floor and defrost. But the most important thing is the gas gauge, I could have me involved in an accident both time.
Fuel gauge system stopped working creating a dangerous situation since you dont know when you can run out of gas particularly on a major highway.
2006 GMC Envoy; replaced timing chain, failure of fuel pump, oil pump, electrical system driver's side door, washer fluid pump, tailgate latch failure and rear wash fluid line failure. Replaced or fixed all issues except, tailgate latch, rear washer fluid line, oil pump issue and SUV will not hold oil pressure.
I have had 2 problems with this vehicle. The first one was at 28000 miles, about 3 weeks after I bought the vehicle. The resistor for the heat/ac fan caught fire while I was driving at about 5 mph in heavy traffic. The fire went out on it's own by the time I had room to pull over (about 15-20 seconds). I was unable to get the part replaced right away so I had to drive around in cold and icy conditions without even being able to run the defroster. The second problem was that at about 32000 miles my gas gauge broke. I had just filled the tank and was driving at about 65 on the highway. The gas gauge needle dropped to empty and stayed there. I made sure that I was not leaking gasoline and continued on my way. It worked intermittently for a while but is now completely broken. When I fill up my tank the engine light comes on for the first 25-100 miles and the gauge reads empty with the fuel light on. I am uncomfortable with using the 4wd or towing very much because even though I keep track of miles driven these things eat up more fuel. I don't want to run out of gas in the middle of the road. I have not gotten it fixed because of the repair cost.
Check engine light accompanied by engine cut-off when cold weather since November 2009. Twice GMC dealership couldn't duplicate issue and no idea for check engine light. New development of fuel gauge failure each time of gas fill-up accompanied by fluctuating fuel level indicator. Clicking noise coming from gas pedal for 3 years with increasing frequency. Electrical system including gauges, speedometer, power steering noise, cruise control seem to be having issues. Dealership claims no recalls, but electrical issues appear to be common according to edmunds. Com forums for GMC Envoys.
The contact stated the accelerator pedal in the vehicle became stuck under the floor mat. The contact stated the floor mats were too big. The vehicle was taken to the dealership and there was nothing that could be done about the problem. The consumer stated the pedals are designed differently now. Updated 02/06/07.
