Recently reported ELECTRICAL SYSTEM problems on 2006 GMC Envoy

This is the second time my blower motor and blower motor resistor has blown out in two months. me and my two children had to drive from alabama to virginia on our family vacation in 110 degree weather without any air. suv smelled liked melted wires. when i took it in again to have it diagnosed. mechanic said these keep having the same problems. this is horrible. another repair out of state will cost me $550, gmc needs to recall these [xxx] trucks!!! *js information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Fuel gauge has stopped working properly. when tank is filled, the gauge reads empty and fuel light is on. when the fuel level begins to decrease below the full level from driving the vehicle, the gauge fluctuates between the completely full mark and the empty mark. this fluctuation can occur during a trip that is less than a few miles. *tr

When turning the key on the vehicle sometimes does not start and has twice from when i got it in feb 2012 all the internal electronics have shut down while driving

The tailgate will occasionally not open. the actuator has already been replaced. the electrical system seems to also "act"up when this happens. the remote takes several times to open the doors. we have replaced the battery several times, the dome light does not come on anymore, the stereo turns off immediately when you turn the engine off, instead of staying on until you open one of the doors. *tr

Tl* the contact owns a 2006 gmc envoy. the contact stated that the vehicle emitted a strong burning odor while driving at various speeds. the contact inspected the vehicle and found that the driver's door panel and wires were burned due to a defective switch. the vehicle was not repaired. the manufacture was made aware of the failure. the vin was not available. the failure mileage was 120,000 and the current mileage was 129,000.

Drivers side power-window, door-lock, remote outside mirror control. referring to the gmc recall of aug 18, 2012 of replacing of the power window switch. after contacting gmc ref# [xxx], my vehicle is not in the vin range for repair. the front windows will not go down, drivers door lock will not work, rear windows go down and up by themselves, outside mirrors change position with no intervention.bought this vehicle new in 2006. we use it extensively as we are traveling nurses. please look into this so we can get our envoy repaired.gm spokesman [xxx] stated that owners not living in the recall states will be covered by the recall. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Tried to turn on the air conditioning and discovered the fan did not work. after quite a bit of research and an expensive diagnosis, was informed the blower motor resistor was burned out. this appears to be a common, frequent, and expensive problem if done by the dealership. there are several potential hazards to families and children which include; the possibility of fire caused by the heated & melted wire, loss of air conditioning in the heat of the day which may cause heat stroke or worse, and loss of heat during the winter months making it impossible to drive safely without the windows icing over and inhibiting vision. a recall in order to repair the problems with the blower motor resistor is necessary. mechanic states that both chevrolet and gmc model vehicles from 2004 to 2007 are being repaired with this exact problem. he has repaired 5 vehicles this month in the state of alabama. mechanic also states that mileage is not the issue as he has seen low mileage gmc and chevrolets come in for repairs with this exact same problem. please respond to this very expensive safety/ health issue as a vehicle recall.[xxx] information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

When driving my envoy home from work the window starting going down by itself and then it made a horrible noise like a grinding noise. then the window started going back and smoke started poring out of the door locks and by the vent on the drivers side of the door. smoke was pouring out i had to pull over and when i got out it smelled liked burnt rubber. it continued to smoke for about 5 mins. and then it stopped. the smell is still in my car but i have no electric functions on the drivers side door. my windows do not work, the outside mirror does not work, the seat controls do not work, the heated seated seats do not work. *tr

Gas gauge malfunctions after filling vehicle due to repeated, documented manufacturers defect in gas tank fuel sensor, possibly leading to a complete failure of indication system. *tr

When i went out to my truck in the morning my vehicle was full of smoke, the drivers side electrical on the door doesn't work, door lock. windows don't work, mirror doesn't work keyless entry either, i went to the dealer they said it was a drivers side master doorswitch failure, they wanted $350.00 to fix we only had the vehicle less than 30 days didn't make 1st payment yet. we saw in the newspaper that these vehicles have this problem so were hoping you can generate enough energy into this problem so we can get this fixed. *tr

The heat and air fan resistor caught on fire causing the electrical system to catch on fire. smoke coming from under the dash and from the glove box. the surge had caused the head light wires to burn into. such a mess...fuel gauge had stopped working about a year prior to that .now the power steering is having a problem. what next..... *tr

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....... *tr

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! *tr

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

Tl* the contact owns a 2006 gmc envoy. the contact stated that the vehicle stalled while driving approximately 30 mph. the contact merged to the shoulder, powered off and restarted the vehicle. the vehicle was taken to the dealer for diagnostic testing. the technician stated that the alternator and the battery needed to be replaced. the vehicle was taken to the dealer on multiple occasions for the same failure. the manufacturer was not made aware of the failure. the vehicle was not repaired. the approximate failure mileage was 85,000 and the current mileage was 104,000. *tr

The fuel gauge does not read correctly. this has caused the vehicle to run out of gas several times now in the middle of traffic due to the gauge telling me i had more fuel than i actually had. *kb

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. *tr

Submission from constituent re recalls-2006 gmc envoy. *smd the consumer stated, her husband was driving, when suddenly the vehicle stalled. he was able to coast safely to a stop. however, the vehicle would not re-start, and the vehicle had to be towed. according to the invoice, the ignition cylinder was replaced. also, on numerous occasions, the air bag light illuminated, and remained on for days. the consumer referenced recall # 06v417000. *jb updated 06/10/14 *jb updated 10/14/14 *jb

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. *tr

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. *lj

Incorrect fuel level reading may result in the vehicle running out of fuel without warning to the driver

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.

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.

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.

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. *tr

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. *tr

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. *tr

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. *tr

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. *tr

Tl* the contact owns a 2006 gmc envoy. the contact started the ignition and the fuel gauge displayed an inaccurate reading even though fuel had been dispensed into the fuel tank. while driving, the fuel gauge reading fluctuated which caused difficulty in determining the actual fuel tank level. in addition, the air bag warning indicator illuminated continuously whenever the vehicle was operative. there were also electrical issues which contributed to the radio not to function and the instrument panel cluster lights would not illuminate. the fuel sensor was replaced previously by the dealer and the failure recurred three years later. the vehicle had not been repaired for the most recent fuel gauge malfunction. there were no repairs performed in relation to the other failures. the manufacturer was notified of the problem. the approximate failure mileage was 23,000. updated 4/2/12 *cn the consumer stated the fuel level sensor failed twice. also, ai =r bag warning light was fixed by moving the srs wiring under the driver's sat. the radio and dash lights were replaced as well, due to inferior parts. updatd 04/16/12

Fuel gage stopped working. fuel gage needle stayed on e after filling up. stalled in left lane of interstate 80 in denville,new jersey with my two daughters. their ages at time of incident were eight and eleven. almost rear-ended by tractor trailers. all three of would have been killed if the truck driver had not been alert and swerved to avoid us as i slowed and navigated to right shoulder. *tr
