2005 GMC Envoy Xl 370

WHILE TRAVELING ON THE INTERSTATE IN THE EVENING, THE SPEEDOMETER BECAME "STUCK" AT ABOUT 30 MPH. WE PULLED OFF AT A REST STOP AND TURNED OFF THE ENGINE, HOPING THAT THE SPEEDOMETER WOULD RESET ITSELF. UPON RESTARTING THE VEHICLE, THE SPEEDOMETER SAT AT 60 MPH, EVEN THOUGH WE WERE STILL SITTING AT THE REST STOP--NOT MOVING. WE TRIED TURNING OFF THE ENGINE AGAIN AND THIS TIME WHEN WE RESTARTED THE VEHICLE, THE SPEEDOMETER NEEDLE "STUCK" AT OVER 120 MPH--AGAIN WE WERE NOT MOVING. THE SPEEDOMETER NEEDLE STAYED PAST THE 120 MPH MARK FOR THE ENTIRE TRIP HOME. FORTUNATELY, WE WERE ABLE TO FOLLOW SOME FRIENDS HOME. A FEW DAYS LATER, WE TOOK THE CAR TO A MECHANIC. HE INDICATED THAT HE HAD SEEN THE SPEEDOMETER PROBLEM BEFORE WITH OTHER GMCS AND HE THEN REPLACED THE "INSTRUMENT CLUSTER" IN OUR VEHICLE. WE ALSO DID A LITTLE RESEARCH AND DISCOVERED THAT SEVERAL GMC MODELS HAD BEEN RECALLED DUE TO PROBLEMS WITH THE SPEEDOMETER, BUT THE RECALLS DID NOT APPEAR TO INCLUDE THE 2005 GMC ENVOY. *TR

AIR CONDITIONER QUIT WORKING ON LEVEL 5, WOULD WORK ON LEVEL 1-4, LEVEL 5 WOULD KEEP TURNING OFF. SHORTLY AFTER THIS WITHIN THE SAME DAY I COULD SMELL SOMETHING BURNING COMING THROUGH THE AIR VENTS. MECHANICS NOTED AND SHOWED ME THAT THE RESISTOR PLUGS ON THE BACK HAD BURNED AND MELTED TOGETHER, THAT'S WHAT WAS CAUSING THE BURNING SMELL. NEEDED A NEW RESISTOR, PIG TAIL, AND BLOWER. ALSO MY FUEL GAUGE AND RPM ARE BROKE, HAVE NOT BEEN WORKING FOR THE PAST 3 YEARS. *TR

THE SPEED CONTROL NEEDLE WAS STUCK BETWEEN 60-120MPH ON 05-05-2012. NOW 05-09-2012 THE SPEED CONTROL NEEDLE IS STUCK AT 120MPH AND DOES NOT RETURN TO 0MPH. THE VEHICLE HAS ONLY 65,000 MILES AND HAS BEEN TO THE DEALERSHIP SEVERAL TIMES FOR PANEL CONTROL PROBLEMS (AIR BAG) WHICH IS STILL NOT FIXED EXTENDED WARRANTY IS NOW EXPIRED. *TR

THE SPEEDOMETER FAILS TO REPRESENT TRUE VEHICLE SPEED. USING A GPS WE CAN MONITOR THE INACCURACY IN THE GAUGE READING. THE SPEEDOMETER REFLECTS A SPEED OF 25 WHEN ACTUAL SPEED IS 45. THIS BECOMES WORSE AS THE VEHICLE IS DRIVEN AS THE SPEEDOMETER COMPLETELY FAILS TO REGISTER SPEED. AN IDENTICAL ISSUE WAS PRESENT ON A 2003 CHEVROLET TRUCK WE OWN WHICH WAS REPAIRED BY GM UNDER AN IN-HOUSE PROGRAM RESULTING FROM A LAWSUIT. GM HAS DECLINED TO REPAIR THIS SAME PROBLEM ON THIS MODEL. IF A DRIVER CANNOT ACCURATELY DETERMINE HIS/HER SPEED AT ANY GIVEN MOMENT THE POSSIBILITY FOR SAFETY RELATED INSTANCES ARE INCREASED FOR THE DRIVER AND OTHERS. *TR

BOUGHT MY 05 ENVOY XL WITH ABOUT 55,000 MILES SINCE THEN THE FUEL GAUGE READS EMPTY WHEN ITS FULL. THE OIL PRESSURE GAUGE IS MAXED OUT BUT IT WILL WORK NORMAL EVERY ONCE IN A WHILE. THE SPEEDO READS FASTER THAN IM GOING OR JUST MAXES OUT. IF I TURN THE CR OFF AND ON IT WILL WORK ITS WAY BACK TO NORMAL FOR AWHILE. THE STEREO WILL NOT WORK IF IT IS COLDER THAN 60 DEGREES OUT. TALKED TO DEALERSHIP AND GMC CUSTOMER SERVICE THEY DID NOTHING. *TR

I HAVE A 2005 ENVOY AND I AM HAVING ISSUES WITH THE FUEL GAUGE AND THE SPEEDOMETER CLUSTER. I FILL UP THE TANK AND IT DOES NOT READ FULL, IT CONTINUES TO READ EMPTY. WHILE DRIVING MY SON BACK TO SCHOOL WITH MY THREE SMALL CHILDREN IN THE CAR THE SPEEDOMETER JUST STOPPED WORKING. IT WAS SHOWING THAT I WAS GOING 120 MILES WHEN I WAS ONLY GOING 40 ISH. THE OTHER THING THAT SHOCKS ME IS THAT THERE HAS NOT BEEN A RECALL ON THESE ISSUES. IT HAS TO BE SOME SORT OF DEFECT BECAUSE THERE ARE SO MANY CONSUMERS WITH THE SAME ISSUES. *TR

I HAVE A 2005 GMC ENVOY AND I HAVE HAD TO REPLACE A WATER PUMP, A BLOWER MOTOR WIRING HARNESS THAT MELTED INTO MY TRUCK, THE LIGHTS ARE HALF OUT ON ME HEATER AND MY DOOR PANEL WHERE YOU PUT THE WINDOWS UP AND DOWN, THE WINDSHIELD WIPER IN THE BACK WORKS WHEN IT WANTS MY SPEEDOMETER IS STUCK ON 40 EVEN WHEN ITS OFF AND MY CHECK ENGINE LIGHT IS ON AND I BOUGHT THIS TRUCK LESS THAN 2 YEARS AGO! *TR
