2005 GMC ENVOY XL 370 Electrical System Problems

I HAD TROUBLE WITH THE GAUGE THAT SHOWS OVERHEATING.I TOOK THE CAR IN TO PUT IN A THERMOSTAT THINKING IT WAS THE PROBLEM,BUT WHEN I TOOK IT IN THEY SAID THAT MY CLUSTER WAS BAD AND THE GAUGES WERE MESSED UP.I PAID $392.00 FOR THE CLUSTER AND $100.00 FOR LABOR.I BOUGHT THIS VEHICLE USED WITH 119,000 MILES ON IT ON 6/20/2011 AND ON 2/23/2013 I HAD THE CLUSTER REPLACED WITH MILEAGE OF 132,356. I PUT ON NEW BRAKES AT THIS TIME SINCE THE HAD A HABIT OF GRABBING AND MAKING ME SLIDE AND JERK TO A STOP.THE ONLY PROBLEM I HAVE NOW IS THE THE DOOR LOCKS MESS UP ONCE IN AWHILE BUT OTHER THAN THAT I TAKE MY ENVOY IN EVERY 4000 MILES FOR AN OIL CHANGE AND A CHECK UP IT IS NOW 12/15/2015 AND I ONLY HAVE 142,000 MILES ON IT AND IT IS STILL RUNNING OK.I...

TL* THE CONTACT OWNS A 2005 GMC ENVOY XL 370. WHILE DRIVING APPROXIMATELY 30 MPH, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED AND THE ENGINE STALLED. THE VEHICLE WAS TOWED TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THERE WAS A LOOSE BOLT WITHIN THE VEHICLE'S SENSORY SYSTEM. THE VEHICLE WAS REPAIRED, BUT THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 142,000.

TL* THE CONTACT OWNS A 2005 GMC ENVOY XL 370. THE CONTACT STATED THAT WHEN THE IGNITION WAS TURNED TO THE ON POSITION, THE SPEEDOMETER DISPLAYED 35 MPH WHEN THE VEHICLE WAS NOT IN MOTION AND THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE CONTACT STATED THAT THE OIL AND THE TEMPERATURE GAUGES WERE NOT FUNCTIONING. THE FAILURE RECURRED CONTINUOUSLY. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE ENTIRE INSTRUMENT PANEL NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS UNKNOWN.

THE OIL GAUGE WENT OUT FIRST AND THE DEALER STATED THE OIL SENDING UNIT NEED TO BE REPLACE AND IT WOULD COST ME OVER 300. 00 DOLLARS, THEN NEXT THE ENGINE COOLANT GAUGE STARTING GOING CRAZY. I TOOK MY CAR BACK FOR AN OIL CHANGE AND WAS TOLD THE INSTRUMENT PANEL CLUSTER NEEDS REPLACING. I WENT BACK TO HAVE MY ENGINE COOLANT GAUGE LOOK AT BY THE DEALER BECAUSE I DID NOT WANT TO BE STRANDED SOMEWHERE WITH MY 4 YEAR TODDLER IN THE CAR AND PAID FOR THE DEALER TO REPLACE THE ENGINE COOLANT THERMOSTAT BASED ON THEIR INSTRUCTIONS. STILL MY OIL PRESSURE GAUGE WAS PEGGED OUT AND NOW THE SPEEDOMETER GAUGE HAS COMPLETELY STOP WORKING, SO I TOOK MY CAR BACK TO THE GMC DEALER AND WAS TOLD THE INSTRUMENT PANEL CLUSTER NEED TO BE REPLACE AND THAT WOULD TAKE CARE OF THE OIL PRESSURE GAUGE TOO. I...

THIS PIECE OF CRAP VEHICLE IN WHICH THE ENTIRE INSTRUMENT CLUSTER HAS COMPLETELY FAILED STARTING WITH THE FUEL GAUGE. THIS FAILURE THEN LED TO THE FAILURE OF ALL THE GAUGES MINUS AS OF RIGHT NOW THE SPEEDOMETER. THE TAC WORKS WHEN IT WANTS TO. GMC NOW HAS WENT BACK AND WANTS TO "FIX" THE SENDING UNIT ONLY TO THE GAS TANK (GEE....THANKS FOR THE RUSH GM CONSIDERING THIS IS A 2005 VEHICLE AND THE YEAR IS NOW 2013...AND PEOPLE HAVE BEEN COMPLAINING FOR DARN CLOSE TO 10 YEARS ABOUT THEM NOW!! NICE JOB STEPPING UP!!).....THUS CORRECTING THE GAS GAUGE ..WE HOPE (WHICH I HAVE BEEN TOLD WILL PROBABLY LAST FOR APPROXIMATELY 1 YEAR...IF WE ARE LUCKY....OH JOY FOR US!!!) YEA...THANKS GM...I NOW KNOW I WILL HAVE 3/4 OF A TANK OF GAS WHEN MY FREAKIN VEHICLE OVERHEATS ON THE SIDE OF THE ROADWAY SINCE THE REST OF THE GAUGES DO...

WE STARTED NOTICING AFTER A FILL UP AT THE GAS STATION THE GAS GAUGE STILL SHOWED EMPTY. THE GAUGE TOOK OVER AN HOUR OF DRIVING TO MOVE UP TO FULL. IN THE MIDDLE OF THE WEEK LAST WEEK THE VEHICLE RAN OUT OF GAS AND STALLED. WE ADDED HALF A TANK, BUT THE GAUGE STILL SHOWED EMPTY THE NEXT FEW TIMES IT WAS DRIVEN SOMEWHERE. LAST WEEKEND I FILLED UP AGAIN AND THE GAUGE SHOWED EMPTY STILL WITH WARNING INDICATOR ON. AGAIN IT TOOK OVER AN HOUR OF DRIVING FOR THE GAUGE TO REGISTER THE TANK EVEN 3/4 FULL. *TR

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...

INSTRUMENT CLUSTER STOPPED WORKING. I CAN NO LONGER JUDGE SPEED. TIRES CRACKED AND DRY ROTTED ON SIDEWALLS AND HAD TO BE REPLACED AT EARLY MILEAGE. *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 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

2005 GMC ENVOY SMOKE FROM UNDER THE DASH THEN THE BLOWER QUIT BLOWER MOTOR RESISTER BURNED UP AND MELTED WIRING HARNESS AND PLUG AT THE RESISTER DID NOT BLOW FUSE REPLACED RESISTER AND HARNESS 3 MONTHS LATER BURNED UP RESISTER AGAIN AND HARNESS STILL DID NOT BLOW FUSE CONTACTED DEALER THEY TOLD ME TO CHANGE THE SAME PARTS THAT THEY'VE SEEN IT BEFORE I RESEARCHED THE WIRING AND CONSULTED A ELECTRICAL ENGINEER HE SAID THE PROBLEM WAS AT THE BLOWER MOTOR BECAUSE THE RESISTER WAS BETWEEN THE SWITCH AND THE MOTOR IF THE MOTOR WAS WORN AND PULLING TO MANY AMPS THAT IT WOULD BURN THE HARNESS AND RESISTER SO I REPLACED ALL THREE ITEMS AND HAVE NOT HAD A PROBLEM SINCE. *TR

2005 GMC ENVOY SPEEDOMETER FAILURE. WHILE DRIVING THE ENVOY OVER STEVENS PASS ( WASHINGTON STATE) THE SPEEDOMETER BEGAN READING A SIGNIFICANTLY LOWER SPEED THAN MY WIFE WAS DRIVING...AT FIRST SHE TRIED TO SPEED UP FEARING THAT SHE HAD ABSENTMINDEDLY BEGAN TO SLOW BUT SOON REALIZED THAT THE SPEEDOMETER CONTINUED TO REFLECT EVEN LOWER SPEEDS. AFTER GOING TO THE INTERNET I'VE DISCOVERED THAT THIS HAS BEEN AN ONGOING PROBLEM WITH GM TRUCKS FOR THE YEARS 2003 THRU 2007 AND ACTUALLY THERE HAS BEEN A CLASS ACTION LAWSUIT FILED. ( I DON'T KNOW THE DISPOSITION) THE REMEDY IS REPLACING THE ENTIRE GAUGE CLUSTER AT A COST OF AROUND $500. SEEMS UNFAIR CONSIDERING THIS IS A PROBLEM OF GMS' AND APPARENTLY KEPT SECRET WHILE CHARGING THEIR CUSTOMERS FOR THEIR PROBLEMS . [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

SPEEDOMETER ON MY 2005 GMC ENVOY XL IS PEGGED AT 120 MPH AND STAYS THERE ALL THE TIME EVEN WHEN THE VEHICLE IS OFF. I UNDERSTAND THAT THIS IS A WIDE SPREAD PROBLEM WITH GMC PRODUCTS. THERE IS A SERVICE BULLETIN FOR THIS PROBLEM ON MANY GMC PRODUCTS BUT DOSE NOT INCLUDE THE ENVOY LINE. WHY IS THIS? NO ACCIDENT SO FAR BUT VERY UNSAFE DRIVING A VEHICLE WHERE YOU HAVE NO IDEA OF HOW FAST YOU ARE GOING. *TR

I BOUGHT A USED 2005 GMC ENVOY XL A YEAR AGO AND AFTER THREE MONTHS OF OWNING IT THE SPEEDOMETER HAS QUIT ON ME WHILE DRIVING DOWN THE ROAD. I DRIVE ON THE INTERSTATE EVERYDAY TO GO TO SCHOOL AND NEVER KNOW WHAT SPEED I AM ACTUALLY TRAVELING. AT STOP SIGNS MY CAR HAS JUMPED FORWARD ON ME SEVERAL TIMES. LATELY THE CAR HAS BEEN SHUTTING OFF FOR NO REASON. MY HUSBAND IS A MECHANIC AND CAN NOT FIGURE OUT WHAT IS CAUSING THIS PROBLEM. WE CONTACTED A GM DEALERSHIP AND WAS TOLD THAT MY CAR AND THE CHEVY TRAILBLAZERS COME IN WITH THIS PROBLEM ALL THE TIME. WE WERE TOLD IT WOULD COST US BETWEEN TWO AND THREE THOUSAND DOLLARS TO FIX IT. WE CAN'T AFFORD THAT KIND OF MONEY TO FIX SOMETHING THAT SHOULD BE FIXED BY GENERAL MOTORS. IT'S THEIR DEFECT! SOMEONE IS GOING TO GET SERIOUSLY...

GAS GAUGE READS EMPTY AT MOST TIMES, NEVER GIVES ACCURATE MEASURE OF TANK FILL. ALSO CHECK ENGINE LIGHT TURNS ON SPORADICALLY, ALTHOUGH DIAGNOSIS BY ENGINE TECH CONFIRMS NO BAD CODES ARE CAUSING THIS WARNING LIGHT TO GLOW. RESEARCH ON THE INTERNET AND TALKING WITH DEALERSHIPS AND MECHANICS HAVE CONFIRMED THAT THIS IS A VERY COMMON DEFECTIVE PART PROBLEM THAT GM HAS NOT ISSUED A RECALL ON. HUNDREDS, PROBABLY THOUSANDS OF FRUSTRATED DRIVERS. IT EFFECTS GMC ENVOYS, CHEVY TRAILBLAZERS, AND OTHER GM MAKES IN 2004 - 2006. THANK GOODNESS TAXPAYER DOLLARS ARE KEEPING THEM AFLOAT! GOD FORBID THEY ACTUALLY SUPPORT THEIR PRODUCTS AND MAINTAIN CUSTOMER LOYALTY AND INTEGRITY! *TR
