2005 GMC Envoy Electrical System Problems

1) I just purchased the vehicle in Oct 2026 & 3 days after purchase, it broke down in Walmart parking lot due to, all the antifreeze pouring out. 2) December 2026 had to replace the front tires as they were stripped to the threads from rubbing against the fender wells. 3) January 2026 Wouldn’t start, wouldn’t turn over or anything. Had the ignition replaced. Ran fine for one week. 4) Currently won’t start. Broke down.

On steering wheel where the GMC logo is . Melted/Melting from underneath. Some type of clear color gooey. Have been told it is seal for airbag. Also none of the chimes are not working at all example * seat belts, door,blinkers,dashboard chimes *dummy lights*,along with Bose stereo. Last issues are REAR VIEW MIRROR... KEEPS FALLING OFF. have taken to dealership SEVERAL TIMES! Now they are saying that I need to contact my auto insurance provider to put in claims.

The driver side window control caught fire, while the vehicle was sitting overnight. It was sitting by itself without reason to catch fire, but it did burn inside the driver side door.

The contact owned a 2005 GMC Envoy. The contact stated while driving approximately 60 MPH the entire dashboard illuminated and needles on gauges had begun to move independently. The contact heard an abnormal "popping" sound from the front end of the vehicle and gray smoke was emitted from under the hood, the vehicle stalled. The contact was able to pull off of the roadway and placed the vehicle into park (P) with difficulty. The contact exited the vehicle and moved away towards the rear end. The contact stated that she noticed flames under the vehicle located at the front end. The contact stated that within 3 minutes of observing the flames under the vehicle, the entire front end became engulfed by flames. The police and fire department arrived on the scene. The contact stated that the fire department used a chemical to extinguish the flames, the contact stated that the flames had burned not only the front end and front tires but the front part of the passenger cabin including the seats. The contact stated that the highway patrol wrote a report and had been informed by the fire department that the fire appeared to have been caused by the electrical system. The vehicle was towed to an impound lot. The manufacturer had not been informed of the failure. The failure mileage was unknown.

Unknown All the cluster panels quite working. RPM, Speed, Oil, Water, Gas shows always empty. Danger because have to guess my speed and never know if I have enough gas, oil, or water in my car. Also sometimes when I shut off my car I cannot get the key out of the steering column. Cannot leave my car without my keys.

I purchased my vehicle in oct of 2021 in Nov 2021 is when my car started failing my car started to lose power also started smoking from the lower passenger side no warning lights came on besides the oil warning light since Nov 2021 my car has been losing power it only goes up to about 40 m.p.h I have been smelling fuel coming from some where my tail and license plate light and back driver side inside car light stopped working the engine light turns on and off the steering wheel makes the car lose a little bit of power when I turn the wheel or when I roll up and down the windows or adjust my seat my ac does not work the back ac turns on by it's self to the heater does not work when I have it turned all the way to the 5 I hear clicking knocking noises in the back passenger side of the car my fuel injectors had puddles of oil in them the car gets really hot and blows hot air the engine is always hot the seatbelt lights are constantly flashing my check engine light as of today flashes on and off and the car jumps also my car caught on fire under the hood where the O2 sensor is started smoking than caught on fire.

WHILE DRIVING IN A 40 MPH ZONE I GLANCED AT THE SPEEDOMETER AND IT READ 70 MPH! I IMMEDIATELY APPLIED THE BRAKES TO SLOW THE VEHICLE DOWN BEFORE I REALIZED THAT THE SPEEDOMETER INDICATION WAS INACCURATE. UPON COMING TO A COMPLETE STOP THE SPEEDOMETER INDICATED 40 MPH. THIS HAPPENED SEVERAL TIMES BEFORE RESUMING NORMAL OPERATION. SINCE THEN I HAVE NOTICED THE GAUGE "STICKING" WHEN LETTING OFF OF THE GAS PEDAL. THIS IS CREATING AN UN-SAFE CONDITION FOR MYSELF AS WELL AS THE OCCUPANTS OF THIS VEHICLE. I DO NOT KNOW WHEN THE SPEED INDICATION IS TRULY ACCURATE. I HAVE SINCE LEARNED THAT THIS IS A COMMON DEFECT ON THIS VEHICLE AS WELL AS OTHER GM MODELS MADE DURING THIS TIME FRAME. THERE SHOULD DEFINITELY BE A RECALL ON THIS PROBLEM BEFORE AN ACCIDENT OCCURS.

FUEL LIGHT STAYS ON CONSTANTLY & FUEL GAUGE ALWAYS SHOWING EMPTY WHEN VEHICLE RUNNING IN MOTION OR STATIONARY

I HAD JUST DROVE MY TRUCK THE NIGHT BEFORE HEADLIGHTS WORKED FINE. I WENT TO LEAVE THE NEXT NIGHT AND NO HEADLIGHTS AT ALL. SO VEHICLE WAS STATIONARY WHEN I REALIZED I HAD NO HEADLIGHTS. I HAVE TO DRIVE WITH MY BRIGHTS ON AT NIGHT. I HAVE NO REGULAR HEADLIGHTS AT ALL. THEN MY PASSENGER SIDE WINDOW JUST QUIT WORKING AS WELL.

THE GAS GAUGE STAYS ON EMPTY WHEN THERE IS A FULL TANK OF GAS. THERE REAR WINDSHIELD WIPER COMES ON BY ITSELF. THE RADIO PLAYS LIKE IT IS IN A TIN BOX. EVERY SO OFTEN IT WILL PLAY NORMAL. BUT MOST OF THE TIME IT DOESN'T. THIS HAPPENS WHEN IT IS MOVING OR IN PARK.

MY 2005 GMC ENVOY XL HAS THE SAME RECALLED MASTER WINDOW SWITCH UNITS AS OTHER RECALLS, BOTH SIDES FRONT DRIVER AND PASSENGER DOORS BURNT WITH A BAD SMELL AS I WAS DRIVING. WHY? WHY IS MY VEHICLE NOT INCLUDED IN THE RECALL WHEN EVERYTHING IS THE SAME AS OTHER RECALLED VEHICLES ?? I WAS DRIVING ON THE PARKWAY WHEN I NOTICED A BURNING SMELL WITH NOWHERE TO PULL OVER FOR A FEW MILES IN GREAT PANIC WITH CARS GOING PAST ME AT 65 MPH PLUS AS I WAS BEING CAUTIOUS TO GET TO AN EXIT SO I COULD FIGURE OUT WHAT THE PROBLEM WAS. IT WAS THE DOOR SWITCH SO I LIFTED IT OUT OF THE DOOR AND UNPLUGGED IT SO I COULD CONTINUE MY TRIP. SCARY SITUATION . PLUS MY MECHANIC CAN'T GET THE ANSWER IF JUST REPLACING THE SWITCH WILL MAKE IT WORK OR DOES IT NEED PROGRAMMED INTO THE COMPUTER ?

SUV DIES AND WON'T START BACK UNTIL IT COOLS DOWN. I WAS TRAVELING 55 MPH ON A FIVE LANE HIGHWAY AND THE VEHICLE JUST DIED. I HAD THE VEHICLE TOWED TO THE LOCAL DEALER AND IT COULDN'T BE DIAGNOSED.

I'VE HAD MY 2005 ENVOY FOR A LITTLE OVER A YEAR AND HAD MY HEADLIGHTS FLASH ON AND OFF WHILE DRIVING ON THE ROAD AND FREWAY. ON ONE OCCASION WHILE DRIVING ON A TWO LANE HIGHWAY AY NIGHT THE LIGHTS WENT OUT COMPLETELY FOR A FEW SECONDS. I WAS SO SCARED WSS REALLY GLAD FOR NO ONE BEHIND ME OR ON COMING TRAFFIC. ON ANOTHER OCCASSION I HAD TO PULL OVER ON CITY STREET AS MY LIGHTS WERE GOING ON AND OFF AND I COULD SEE THE CAR AHEAD WAS A COP AND I DIDNT WANT HIM TO THINK I WAS FLASHING FOR HELP ESPECIALLY AT 2 IN THE MORNING. IVE ALSO HAD TO EXIT THE FREEWAY BECAUSE MY LIGHTS STARTED GOING ON AND OFF AND ON AND WASNT SURE IF THEY WOULD JUST GO OUT COMPLETELY WHILE I WAS DRIVING AND SINCE IT WAS NIGHT TIME I DIDNT WANT TO TAKE THE CHANCE OF CAUSING AN ACCIDENT AND HURTING SOMEONE ELSE OR MYSELF. I HAVE A TEENAGE DAUGHTER AND AM AFRAID TO TRANSPORT HER AND HER FRIENDS IN MY CAR.

CAR WAS PARKED FOR 10 MINUTES WHEN WE NOTICED SMOKE COMING FROM THE INTERIOR UPON OPENING THE CAR DOOR WE REALIZED THE DASHBOARD WAS ENGULFED IN FLAMES.

READING NUMEROUS COMPLAINTS THAT COMPARE TO MINE THE FUEL GAUGE, OIL GAUGES, AIR CONDITIONER ARE ALL MALFUNCTIONING IN MY CAR AND I'M VERY UPSET BECAUSE ALL OF THIS SHOULD HAVE BEEN RECALLED. I PURCHASED MY CAR BRAND NEW IN 2005 AND I WILL NEVER BUY A GMC CAR AGAIN FOR THIS REASON IT'S ONE THING TO RECALL REPAIR PARTS THAT WERE BROKEN THAT TO REPAIR MALFUNCTION PARTS. VERY DISAPPOINTED. IN SHORT MY GAUGES DON'T WORK, MY AIR CONDITIONER ONLY WORKS ON ONE SIDE AND NOW MY HEADLIGHTS LOW BEAN DON'T WORK. GMC NEEDS TO RECALL AND REPAIR.
