2006 GMC ENVOY Complaints

MY 2006 GMC ENVOY'S GAS GAUGE HAS BEEN FLUCTUATING FROM EMPTY TO FULL ON FILL UPS FOR OVER 2 MONTHS AND NOW IT IS STUCK ON EMPTY EVEN WHEN TANK IS FILLED. MY MECHANIC SAID IT WOULD COST $800 TO REPLACE THE FUEL SENDING UNIT AND FUEL PUMP. MANY OTHER OWNERS HAVE SIMILAR ISSUES. *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.

TL*THE CONTACT OWNS A 2006 GMC ENVOY. WHILE DRIVING APPROXIMATELY 30 MPH, THE VEHICLE VIBRATED AND THE ENGINE STALLED INTERMITTENTLY. PRIOR TO THE FAILURES, THE ENGINE WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER AND THEY REPLACED THE INTAKE VALVE, HEAD GASKET, TIMING BELT, AND CYLINDER HEAD. THE FAILURES RECURRED ON A SEPARATE OCCASION. THE VEHICLE IS CURRENTLY NOT BEING DRIVEN DUE TO THE SAFETY RISK INVOLVED. THE CONTACT WILL TAKE THE VEHICLE TO THE AUTHORIZED DEALER FOR DIAGNOSTIC TESTING AND REPAIR. THE FAILURE MILEAGE WAS 14,000 AND CURRENT MILEAGE WAS 16,000.

2006 GMC ENVOY DENALI PURCHASED 12/05. BEGINNING AT ABOUT 10,000 MILES THE TRANSMISSION WOULD SHIFT ABRUPTLY INTO 1ST GEAR AFTER THE CAR HAD STOPPED MOVING. THIS DOES NOT HAPPEN EVERY TIME BUT WHEN IT DOES IT FEELS AS IF THE CAR HAS BEEN HIT FROM BEHIND. DEALER HAS NOT BEEN ABLE TO DUPLICATE THE PROBLEM BUT STATES THAT OTHER OWNERS HAVE REPORTED THE SAME PROBLEM. *TR

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

MY WIFE WAS INVOLVED IN AN ACCIDENT LAST NIGHT IN WHICH THE VEHICLE, A 2006 GMC ENVOY DENALI WAS TOTALED, BUT NEITHER AIR BAD DEPLOYED. *TR

THE FUEL TANK SENSOR MODULE ON MY 2006 GMC ENVOY FAILED CAUSING THE TANK LEVEL INDICATOR TO FLUCTUATE AND READ IMPROPERLY. THE VEHICLE HAD ONLY ABOUT 41,000 MILES ON IT AND WAS APPROXIMATELY TWO YEARS OLD. *TR THE FIX WAS TO REPLACE THE MODULE, AT A COST OF $700. THIS IS AN EXCESSIVE PRICE FOR A MODULE THAT SHOULD HAVE LASTED LONGER THAN TWO YEARS.

FUEL LEVEL SENSOR (2006 GMC ENVOY XLT) IT WAS FLOATING BACK AND FORTH AT FIRST THEN IT RESTS ON "E" AND THE LIGHT STAYS ON AND THE ALARM KEEPS RINGING THAT MY FUEL LEVEL IS LOW. IT HAS LEFT ME STRANDED MORE THAN ONCE. I HAVE CONTACTED GM AND WAS TOLD THAT THEY HAVE HAD SEVERAL VEHICLES COME IN WITH THE SAME PROBLEM. NOW IT DOESN'T FLOAT AT ALL IT JUST STAYS ON "E" AND THE LIGHT AND BELLS ARE ON.

WHILE DRIVING, CHECK ENGINE LIGHT CAME ON. FUEL TANK GAUGE STARTED TO CONTINUALLY SHIFT FROM WHATEVER STATE THE FUEL TANK WAS IN TO EMPTY THEN AFTER SOME TIME REVERT BACK TO NORMAL FUEL CAPACITY AT THE TIME. CONTACTED ONSTAR FOR A DIAGNOSTIC AND THEY STATED THERE IS A PROBLEM WITH THE FUEL SENDING UNIT. *JB

TL*THE CONTACT OWNS A 2006 GMC ENVOY DENALI. WHILE ATTEMPTING TO DECELERATE FROM APPROXIMATELY 3-5 MPH, THE VEHICLE ACCELERATED AND STRUCK THE REAR OF ANOTHER VEHICLE.
