2003 GMC Envoy Electrical System Problems

The contact owns a 2003 GMC Envoy. The contact stated that while in drive(D), the vehicle shut off and then restarted. The message “Service Engine Soon” was displayed. The vehicle was taken to the local dealer, where it was diagnosed and determined that the instrument cluster needed to be replaced. The vehicle was repaired, but the failure reoccurred. The vehicle was taken back to the dealer who installed the original instrument cluster, but the failure persisted. The manufacturer was not notified of the failure. The approximate failure mileage was 98,000.

The car's gas gauge and fuel range indicator are problematic. The fuel gauge quickly drops from a higher reading, like 3/4 full, to empty. After this, the gauge and the fuel range both fluctuate while driving, making it impossible to determine the fuel level.

VEHICLE CAUGHT FIRE UNDER DASH SOMEWHERE WITHOUT VEHICLE BEING TURNED ON.

I WAS DRIVING DOWN THE ROAD WHEN THE CAR SHUT DOWN EVERYTHING I WAS SCARED BECAUSE I HAD TRAFFIC RIGHT BEHIND ME GOING 45MPH AND THEN THEY CAR WOULD NOT RUN AGAIN. I WAS RIGHT IN THE MIDDLE OF AN INTER SECTION AT HALL ROAD AND 59 IT WAS THE SCARIEST THING THAT HAS HAPPENED TO ME. I BOUGHT THIS VEHICLE AS A USED AUTO AND I'M NOT SURE IF THE EMMISSION SYSTEM EVER GOT CHANGED AND THIS HAPPENED ONCE BEFORE AND THE DEALER SAID NOT TO DRIVE WITH MY HOUSE KEYS ATTACHED. I HAD TO GET THE AUTO TOWED HOME.

THE ELECTRIC WIRING FOR THE WINDOWS AND SIDE MIRRORS WILL START MAKING A CLICKING NOISE AND WHEN I PUT THE KEY INTO THE IGNITION AND TURN THE KEY JUST ONE TURN THE FRONT PASSENGER WINDOW GOES COMPLETELY DOWN AND WILL NOT GO BACK UP UNTIL IT IS DONE CLICKING AND TURNING THE HEATED SEATS ON AND OFF. THE REGULATOR IS NOT BROKE. ALSO THE SIDE MIRRORS EVEN THOUGH THEY ARE PROGRAMMED WILL SOMETIMES JUST START MOVING AND ACT LIKE IT CANT MOVE ANYMORE AND MAKE A NOISE. THE MUSIC AND OR RADIO WILL GO OUT WHILE ITS TURNED ON, IT WILL CUT IN AND OUT AND THEN AFTER DRIVING A WHILE IT WONT CUT IN AND OUT. FOR THE WINDOW TO JUST ROLL DOWN IT USUALLY HAPPENS AFTER IT SAT ALL NIGHT. WONT GO BACK UP FOR AT LEAST 2 MINUTES AND YOU CAN SEE THE DOOR LIGHTS FLICKER AND CLICK.

THE LIGHTS COME ON BY THEMSELVES AND DRAINS THE BATTERY. TWO BATTERIES HAVE BEEN INSTALLED. THE CAR HAS HAD ROAD SERVICE JUMP STARTS 3 TIMES IN 2 WKS. THE LIGHTS COME ON THEMSELVES WHEN THEY'R'E OFF. THE ALTERNATOR WAS CHECKED AND IS GOOD. THE VEHICLE WAS PARKED IN A GARAGE WHEN THIS OCCURRED AND 1 TIME IN A PARKING LOT.

WHILE DRIVING ON THE HIGHWAY AT 65 MPH, THE THIRD ROW FLOOR GOT REALLY HOT AND MY CHILDREN WERE SAYING THEIR FEET WERE REALLY HOT AND WE SMELLED SOMETHING LIKE PLASTIC MELTING AND MY 15 YEAR OLD COUSINS BOOT MELTED AND THE CARPET MELTED AND YOU CAN SEE METAL. ONCE WE ARRIVED HOME THE BLINKER STAYED ON AND DID NOT SHUT OFF UNTIL THE BATTERY DIED. JUST BEFORE THIS HAPPED THE VEHICLE LOST POWER AND MY HUSBAND HAD TO PUT HIS FOOT ON THE GAS ALL THE WAY.

THE DASH CLUSTER DOES NOT WORK CORRECTLY, ALL THE LIGHTS TURN ON AND DOORS LOCK WHILE I AM DRIVING ON IN TOWN OR ON THE HIGHWAY , ALL THE GAUGES COME ON AT ONCE WHILE DRIVING ON THE STREETS AT RANDOM TIMES.. THE REAR HAS AIRBAGS IN THE SUSPENSION AND AND AREN'T WORKING PROPERLY, I TOOK IT TO THE SHOP AND THEY SAID IT HAD 30 CODES ON THE DIAGNOSTIC MACHINE BUT THEY COULDN'T FIND THE PROBLEM
