Well I have a 2006 envoy, the battery hand bounces between 0-14 volts replaced the battery,had the alter nator checked and its fine. I talked to the guy at a gmc deal he said its the dashboard switches.. And the check engine light comes on and off, he said its a sensor or the dash panel. Who knows. You shouldn't have to go thru al this hassel. I want mine fixed.......

Tl* the contacts owns a 2006 gmc envoy. The contact stated that the fuel gage indicated inaccurate levels on the instrument panel. The dealer and manufacturer were contacted but the vehicle was not repaired. The failure mileage was unknown and the current mileage is 71,223. Updated 08/01/11*lj updated 08/11/11
While driving gmc envoy wipers move by themselves. Then stop after a min. Or so! As we pull out of the driveway water sprays and windshield wipers move constantly by themselves. All of these factors create horrible visability!
Electrical system has issues. The truck (with a new battery) need to be jumped. Occasionally it will turn without a jump, the radio and other electrical items reset. The stabilitrac light comes on.
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.
Driving at normal highway speed, the fuel gauge would register full, then would register empty, the low fuel warning light would illuminate, and the fuel gauge would not work again. The check engine light would come on and when I took the car to a mechanic, I was informed that I had a bad fuel sensor. This is a common problem and urge the safety administration to force gm to issue a recall. The safety factor, is running out of fuel with no warning on a street or highway and no safe way to pull off the roadway out of harms way.
Tl* the contact owns a 2006 gmc envoy. The contact stated the air conditioner was activated and there was an abnormal burning odor. The vehicle was taken to a local repair facility where the mechanic advised that the harness switch had overheated and burned. The vehicle was not repaired. The manufacturer was not contacted. The VIN was unavailable. The failure mileage was 117,450.
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.
Driving when three lights showed up on instrument panel stabilitrak, check engine and reduced engine power light came on the envoy completely turned it self off. I waited a few minutes then started the car. It started the check engine light was the only light on. I got home and restarted car all lights disappeared. Next day driving the same thing happen. Three more times on the way to mechanic the envoy turned itself off. Find out the programmable control module PCM was defective. This car was purchased as a certified used vehicle 07/08. I then find out the part is readily available and not a special order. They refurbish this part with a one year warranty. I can not believe that gmc would engineer a car to entirely shut down when driving this could have been very dangerous had I been on the freeway going 65 MPH, also that this should not happen as it is not a wear and tear issue. The codes that showed up were apparently not covered by gmc. With this part being readily available I must not be the only one who has had this happen. This was a costly repair, and I feel that someone should look to see if this has happen to others, before someone gets hurt or killed.
Tl* the contact owns a 2006 gmc envoy. While driving at speeds of 65 MPH, the power door lock switch caught on fire. The dealer advised the vehicle could be repaired but the part needed to make the necessary repairs was not available and would not be available for another six months. The vehicle had not been repaired. The current and failure mileages were 65,000. Updated 11/03/10.
Incorrect fuel level reading may result in the vehicle running out of fuel without warning to the driver
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.
Wife's 2006 gmc envoy heater lights,and high blower quit working,took to corner service station to find out what was wrong and fuse block on heater motor was melted.talked to mike and he said when he opened service book,it told of this problem to check it first,needs wiring harness and fuse block replaced. If it melted together it sounds like a fire hazard,if it is first place to look in repair manual,sounds like its a defective parts problem.
Stabilitrac and/or ABS system engages when not necessary such as driving on dry, straight pavement at highway speeds. Causes vehicle to decelerate suddenly and almost lose control when brakes activate and motor retards. Electrical system also fluxuates (altimeter bounces from low to hi) causing a loss of power with associated loss of steering, lights, braking controls, at any speed. Problem has been increasing (frequency & severity) from july, 2009 to present (jan, 2010). Dealer shop did stabilitrac tsb firmware upgrade (and charged me) w/o correcting problem, also retested and "could not find anything wrong":battery is new but problem persists. 55,000 miles, mostly highway/improved roads. This occurs every time, literally, the vehicle is moved: 30-40 miles/day. 1/6/10 engine developed "low growl" noise and RPM dropped from ~800rpm to ~600rpm at parked idle w/o any apparent cause. Now idle at start is normal, but within 1-2 minutes drops and remains low with growl noise.
Tl*the contact owns a 2006 gmc envoy. She experienced failures with the ABS system. The fuel gage registered empty when the gas tank was full and also the seats and windows electrical switch. While driving at night on august 11,2009 all lights failed. She will take the vehicle to the dealer. The failure mileage was unknown and the current mileage was 41,590.
Fuel gauge bounces around even when full with gas. When filled,the gauge needle gets buried at empty with light and sound dinging. Then the check engine light comes on.
I parked my car and went into a store and when I came out I could smell a burning smell. My car would not unlock from the drivers door and when I got into my car I seen that my electrical panel on the drivers side blew up.
Tl*the contact owns a 2006 gmc envoy. The contact smelled a burning odor coming from the vehicle and parked it overnight. The following morning, the air conditioning system would not operate. The dealer stated that there was a heating resistor that melted some of the wires in the ignition system. The wiring harness was replaced and the dealer advised the contact not to activate the air conditioning system on low power; only medium and high due to the power needed by the blower when running on low. After the repairs were made to the wiring harness, the fuel gauge became inoperable on the instrument panel. The failure mileage was 26,000 and current mileage was 27,000.
Starting in december 2007 every time I fill my gas tank the sensor light comes on and stays on, after a few miles the check engine light comes on. The gas gauge reads empty, then it will read something else. So I have to always reset my mileage so that I know how far I have went. This gmc is only 2 years old. It drives me nuts with this problem. It will finally reset to where the light goes off and the check engine light will go off. For a couple of days then I have to fill it again. I almost dread going to put gas in.
