• 12/30/2010· VEHICLE SPEED CONTROL

  2005 GMC ENVOY XL 64,900 MILES. SPEEDOMETER ERRATIC OPERATION. SINCE FIRST INCIDENT, SYMPTOMS UNDER VARYING DRIVING CONDITIONS ARE; SPEEDOMETER ERRONEOUSLY INDICATES TOO LOW A SPEED, SPEEDOMETER INDICATES TOO HIGH A SPEED, SPEEDOMETER INDICATION STICKS AT A FIXED SPEED WITH CHANGING VEHICLE SPEED.

• 12/30/2005· ELECTRICAL SYSTEM

  (2005 ENVOY) ABOUT 1 MONTH AGO I NOTICED THAT MY HEADLIGHTS WERE DIMMING WHILE DRIVING AT NIGHT . THIS HAPPENED SPORADICALLY. WHEN THE LIGHTS DIM, THE HEAT SLOWS DOWN AS WELL. THE INTERIOR LIGHTS OCCASIONALLY DIM WHEN THIS HAPPENS, TOO. MY HUSBAND AND I THOUGHT IT MIGHT BE THE BATTERY AND STARTED TO LOOK AT THE BATTERY GAGE, WHILE ONE OF US KEPT AN EYE ON THE LIGHTS. THIS PROBLEM HAS HAPPENED ABOUT 7 TIMES OVER THE LAST MONTH. LAST WEEK IT HAPPENED ABOUT EVERY 2 MINUTES WHILE DRIVING DOWN THE ROAD. VERY SCARY, AS I THOUGHT THE TRUCK WAS JUST GOING TO SHUT DOWN. I TOOK THE TRUCK TO MY GM DEALER AND THE MECHANIC SAID THAT THERE IS NOTHING WRONG WITH THE TRUCK. THE BATTERY, ALTERNATOR AND WIRES WERE FINE. HE STATED THAT WITH NEW VEHICLES AND EVERYTHING THAT IS RUN IN THEM THIS IS NORMAL. ALTHOUGH HE ALSO STATED THAT HE HAS NEVER SEEN THIS PROBLEM BEFORE. THEIR COMPUTER TOLD THEM THAT NOTHING NEEDED TO BE FIXED. WE HAVE NO AFTERMARKET PRODUCTS IN THE VEHICLE AND THE ONLY THINGS RUNNING WERE THE HEAT AND RADIO. *NM

• 12/28/2011· VISIBILITY,STRUCTURE

  THE REAR WINDSHIELD OF MY 2005 GMC ENVOY XL EXPLODED FOR NO APPARENT REASON TODAY. I LIFTED THE FULL HATCH (NOT JUST THE WINDOW SECTION) TO PLACE ITEMS IN THE BACK THAT I HAD PURCHASED AT HOME DEPOT. I PLACED A CAN OF PAINT, ONE BAG, AND A BAG OF SAND IN THE BACK - NOTHING THAT WAS NEAR THE GLASS OF THE HATCH. I THEN CLOSED THE HATCH WITH ENOUGH FORCE FOR IT TO CLOSE SECURELY, BUT NOT WITH EXCESSIVE FORCE. AS I WALKED TO THE DRIVER SIDE DOOR TO ENTER THE CAR, I HEARD A LOUD POP THAT I THOUGHT WAS SOMEONE HITTING THE BACK OF MY CAR WITH THEIR VEHICLE. AS I WALKED AROUND TO THE BACK, MY REAR WINDOW WAS SHATTERED INTO A MILLION TINY PIECES. THERE WERE NO OBJECTS OR PEOPLE AROUND THE WINDOW CLOSE ENOUGH TO BREAK IT - IT JUST SHATTERED FOR NO REASON AT ALL! THE DEALERSHIP SAYS THEY HAVE NO RECORD OF ISSUES WITH REAR WINDSHIELDS, BUT I FOUND INFORMATION THAT DIFFERS ON LINE. FORTUNATELY, THE DEDUCTIBLE ON MY INSURANCE IS ONLY $200. HOWEVER, FOR OTHERS, I HAVE SEEN WHERE THEY HAVE HAD TO PAY UP TO $1500 OUT OF POCKET FOR THE EXPENSE BECAUSE THE DEALERSHIP REFUSES TO REPLACE THE WINDOW. THE COMPANY THAT IS COMING TO REPLACE IT SAID THE WINDOW ITSELF COSTS $937, NOT INCLUDING THE INSTALLATION. *TR

  I HAVE HAD A PROBLEM IN THE PAST WITH THE FUEL GAUGE READING EMPTY CONTINUOUSLY AS I HAVE READ FROM MANY OTHER COMPLAINTS. RECENTLY I EXPERIENCED A PROBLEM WITH THE OIL PRESSURE GAUGE. AT FIRST THE CHECK ENGINE LIGHT APPEARED INTERMITTENTLY AND THEN THE OIL PRESSURE GAUGE DROPPED TO ZERO, AT WHICH TIME THE MESSAGE IN ON THE LCD READING SAID "STOP ENGINE" AND "OIL PRESSURE LOW". I IMMEDIATELY WENT TO MY GAS STATION AND CHECKED THE OIL, WHICH WAS ONLY DOWN A 1/4 TANK. MY MECHANIC STOPPED THE CAR AND STARTED IT AGAIN AND THE OIL PRESSURE GAUGE RESET ITSELF BUT ONCE I STARTED TO DRIVE THE CAR AGAIN, THE OIL PRESSURE DROPPED. MY MECHANIC BELIEVES IT IS ANOTHER SENSOR PROBLEM LIKE THE FUEL SENSOR BUT IS NOT COMPLETELY SURE. I ONLY STARTED WITH THIS ISSUE TODAY BUT IT IS MORE WORRISOME TO ME THAN KEEPING TRACK OF HOW MUCH GAS SHOULD BE IN MY TANK. I AM CURIOUS TO KNOW IF OTHERS HAVE STARTED TO EXPERIENCE THIS PROBLEM. I HAVE HAD THE CAR SINCE IT WAS BRAND NEW AND HAVE DRIVE 79000 MILES. I ALSO HAD A MAJOR ISSUE WITH THE SUSPENSION SYSTEM WITH I BELIEVE IS COMMON IN THIS VEHICLE. *TR

• 12/28/2010· ELECTRICAL SYSTEM

  SPEEDOMETER STUCK AT 60MPH WHILE TRAVELING. DIDN'T MATTER IF STOPPED, ACCELERATING, DECELERATING, OR TURNING VEHICLE OFF. TURNING OFF THE CAR AND RESTARTING IT SEEMED TO CAUSE THE SPEEDOMETER TO DECREASE, SOME, FINALLY GETTING IT TO REGISTER 20MPH. UPON RESTARTING THE VEHICLE IN THE MORNING THE SPEEDOMETER STILL REGISTERED 20 MPH AND UPON ACCELERATION THE SPEEDOMETER FLUCTUATED FINALLY SETTLING AT 80MPH. WE WERE UNABLE TO TELL HOW FAST WE REALLY ARE TRAVELING BECAUSE THE SPEEDOMETER IS WACKO. STOPPING AND TURNING OFF THE VEHICLE DOES NOT HELP. THE SPEEDOMETER DOES NOT RESET TO ZERO IT IS NOW STUCK AT 80MPH. OUR LOCAL GM DEALER ADVISED THAT NO RECALL HAS BEEN ISSUED BUT AN EXTENDED WARRANTY TO 75,000 MILES WAS OFFERED ON THE VEHICLE FOR THIS PARTICULAR PROBLEM. OUR VEHICLE IS OVER THE MILEAGE FOR THE WARRANTY. GM IS AWARE THERE IS A PROBLEM WITH WACKO SPEEDOMETERS HENCE THE WARRANTY EXTENSION. ONE WOULD ASSUME BEING ABLE TO MONITOR ONES SPEED IN A VEHICLE IS AN IMPORTANT SAFETY CONCERN. *TR

• 12/28/2009· ELECTRICAL SYSTEM

  THE SPEEDOMETER CONSTANTLY SHOWS DIFFERENT SPEEDS. WILL BE DRIVING DOWN EXPRESSWAY AT 65MPH AND NEXT THING YOU KNOW IT SHOWS 90MPH SO YOU SLOW DOWN 65 AGAIN AND REALIZE THAT EVERYONE FLIES BY. THE BEST I CAN FIGURE IS IT WILL SUDDENLY SHOW A DIFFERENT SPEED THAN ONE IS ACTUALLY GOING FROM 20MPH LESS TO 40MPH MORE. DIFFERENT EVERY TIME. *TR

  REAR WINDSHIELD/BACK WINDOW SHATTERED ON IT'S OWN WHILE PARKED IN PARKING LOT. COULDN'T FIGURE OUT WHY OR WHAT HAD CAUSED THIS TO HAPPEN. TOOK THE VEHICLE TO SHOP FOR WINDSHIELD TO BE REPLACED, AND WHEN I GOT IN THE CAR TO LEAVE THE SHOP THE REAR WINDSHIELD SHATTERED AGAIN. MY DAUGHTER WAS IN THE BACK SEAT AT THE TIME AND THIS SCARED THE CRAP OUT OF BOTH OF US. THE SHOP COULD NOT BELIEVE THIS AND REPLACED THE WINDOW FOR A 2ND TIME. WHEN I GOT HOME I GOOGLED 'GMC ENVOY, REAR WINDOW' AND SEE THIS HAS HAPPENED TO MANY OTHERS WITH ENVOYS OF DIFFERENT YEAR MODELS.

IT ONLY STOPPED WHEN I OPENED THE DRIVER SIDE DOOR. A COUPLE HOURS LATER I WAS ABLE TO DRIVE TO ANOTHER DESTINATION. WHEN I TOOK THE KEYOF OUT, THE LIGHTS FLASHED AND AGAIN THE CLICKING NOISES.

VAN DEVERE DEALERSHIP IN AKRON, OHIO CHARGED $100.15 TO DETERMINE LOCKS WILL NOT WORK; ADVISED ME TO CALL GM CUSTOMER SERVICE. CALLED GM CUSTOMER SERVICE 866-790-5600 X 32380 COMPLAINT FILE 71-585106455; ROBERT JOHNSON STATED THAT THE SERVICE MANAGER OF THE REPAIRING DEALER IN JULY 2006, PREMIER IN RITTMAN, OHIO WOULD NOT REPLACE LOCKS BECAUSE PARTS BEYOND 12 MONTH WARRANTY. I EXPLAINED THAT THIS WAS A SAFETY ISSUE, AND EXPLAINED THE DANGER OF DEFECTIVE LOCKS; ROBERT JOHNSON STATED THERE WAS NOTHING ELSE HE WOULD DO. ASIDE FROM THE POOR QUALITY, LOCKS ARE CRUCIAL TO VEHICLE SAFETY, AND LOCKS ON A 2005 VEHICLE SHOULD NOT FAIL IN 2006 AND 2007. MOREOVER, I AM APPALLED THAT GM WOULD NOT INSIST THAT THESE BE REPLACED IMMEDIATELY AT COMPANY EXPENSE, CONSIDERING THE SAFETY RISK AND EMBARRASSING LACK OF QUALITY. *TR

• 12/16/2021· AIR BAGSCrash

  I purchased my envoy from a used car lot with no warning lights and no apparent safety concerns about 2 yrs ago other then what appeared to be a replaced front bumper cover and the vehicle was repainted the same color white, since then the brakes have intermittently not disengaged on one side or the other I believe it's the front brakes and seems to be worse after a longer drives and after bleeding the system the pedal would be firm and next day spongy feeling and going down rather far. Air bags did not deploy apon impact. It is available for inspiration although I am attempting to repair it after my accident the brakes are still as they were. I have tried both on as well as performance pads and rotors booster check valve and fluid replacement with no change. I was coming back from my daughter's dentist appointment it is 20 minutes away the roads were very slick with snow and sleet, I got off the hwy and coming through town I braked to slow from 45 to 35mph before crossing the intersection when I let off the brake the left side stayed engaged enough to cause the vehicle to pull to the left and I couldn't steer straight because of the snow and was forced to hit 2 traffic light posts in the center median. Usually on dry roads I can tap the pedal and keep it straight until the brakes released. I first noticed it changing pads when I 1st purchased it that the front tires spin harder while jaked up and when it continued I figured it was alignment or steering components worn but even after parts replaced a 2 alignments nothing changed, after my last alignment the technician said the brakes need to be bled and I told him the issue he was unsure the cause. I did not have any air bags deploy in this accident and the sensors were clearly effected as the bumper caved in the center. The vehicle also has had uneven ride height due to independent sensors in the rear. The vehicle now has a service airbag and service brakes light. Other owners have similar issues with their envoys

  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 KEEP CHECKING ONCE A MONTH FOR RECALLS ON MY VEHICLE SOMETIMES A DOME LIGHT WILL COME ON .BUT NOT OFTEN.MY ENVOY HAS NOT RUST AND THE INTERIOR IS IN AS GOOD AS IT WAS WHEN I PURCHASED IT FROM THE PREVIOUS OWNER WHICH IS IN EXCELLENT CONDITION

  FUEL GAUGE PROBLEMS....MY FUEL GAUGE HAS BEEN FLOATING FROM 1/2 A TANK TO EMPTY FOR THE PAST FEW WEEKS AND NOW IT THE FUEL LIGHT JUST STAYS ON EVEN WHEN THERE IS GAS IN THE CAR. AFTER RUNNING FOR A WHILE THE GAUGE WILL SAY THERE IS GAS AND THEN IT WILL GO BACK DOWN TO EMPTY. *TR

• 12/16/2009· ELECTRICAL SYSTEM

  THERE WAS IGNITION SWITCH FAILURE WHILE DRIVING THE VEHICLE. THE POWER STEERING AND BRAKES GAVE OUT, THE ENGINE SHUT OFF, AND ALL THE LIGHTS ON THE DASH CAME ON. IT RESEMBLED THE CAR RUNNING OUT OF GAS WITHOUT DOING SO. AFTER I PULLED OFF THE ROAD WITH GREAT DIFFICULTIES, I PUT THE CAR IN PARK AND THE VEHICLE GOT STUCK IN IT. THE ENGINE WOULD NOT TURN OVER AFTER THIS OCCURRED AND NEEDED TO BE TOWED. THERE IS NO RELEASE SWITCH WHICH THE TOW TRUCK DRIVER SAID THERE SHOULD BE SO HE COULD GET IT ONTO THE TRUCK, SO THE VEHICLE HAS TO BE DRUG WITH THE WHEELS LOCKED ONTO THE FLATBED AND THEN PUSHED OFF IN THE SAME MANNER. WE PAID TO HAVE IT FIXED AND IT HAS NOW HAPPENED AGAIN 5 MONTHS LATER. THERE ARE MANY REPORTS OF THIS ONLINE AND IT IS NOT JUST WITH THE GMC ENVOY DENALI IT ALSO INCLUDES THE CHEVY TRAILBLAZER AND POSSIBLY OTHER VEHICLES MANUFACTURED BY GM. THERE WAS ONE PERSON ONLINE THAT SAID THEY KEEP SPARE IGNITION SWITCHES IN THE VEHICLE AND THE TOOLS TO SWAP IT OUT BECAUSE OF HOW FREQUENTLY IT HAPPENS. THE DEALERSHIP REPLACED THE PART AND IT IS NOT AVAILABLE AS FAR AS I KNOW, BECAUSE IT WAS NOT RETURNED TO ME. THE VEHICLE WAS A 2005 GMC ENVOY DENALI. *TR

  I WAS GETTING MY TANK FILLED WITH GAS AND THE FUEL GAUGE NEEDLE PEGGED OUT PAST FULL, THEN BOUNCED DOWN TO EMPTY. IT DID THIS THREE TIMES THEN WENT BACK TO FULL. SINCE THEN IT HAS CONTINUED TO BOUNCE AROUND. THE ONLY WAY WE KNEW IF WE HAD ENOUGH GAS WAS TO FILL IT AND USE THE TRIP METER. THE FUEL GAUGE HAS CEASED TO MOVE AT ALL SINCE APRIL 2011. THE CHECK ENGINE LIGHT HAS BEEN ON CONTINUOUSLY AS WELL SINCE THE INCIDENT. I LOVE THE VEHICLE BUT IT IS A MAJOR PAIN TO KEEP TRACK OF THE FUEL WHEN 3 PEOPLE IN THE HOUSEHOLD RELY ON IT. I LOOKED ONLINE TO SEE IF THERE WAS A RECALL, ONLY TO LEARN THIS IS A COMMON COMPLAINT AND NOTHING IS BEING DONE ABOUT IT. I PRICED A NEW CLUSTER AND IT WAS OVER $500. NEEDLESS TO SAY WE STILL HAVE TO KEEP TRACK OF THE FUEL WITH OUR TRIP METER. GM SHOULD STEP UP TO THE PLATE AND FIX THIS ISSUE. THEY HAD NO PROBLEM TAKING A BAILOUT. MY FAMILY HAS BEEN BUYING GM PRODUCTS FOR YEARS, HOWEVER, NO ONE IN MY FAMILY WILL EVER OWN ANOTHER GM PRODUCT IF THEY CAN'T DO THE RIGHT THING FOR THEIR CONSUMERS, AND DO IT NOW. NOT 5 YEARS FROM NOW!! *TR

  I WAS DRIVING DOWN THE HIGHWAY WHEN I NOTICED THAT THE SPEEDOMETER INDICATED THAT I WAS GOING 90+ MPH. I SLOWED DOWN TO THE POINT THAT PEOPLE WERE PASSING ME IN A 65MPH ZONE AND MY SPEEDOMETER WAS INDICATING 60 MPH. I PULLED OVER AND STOPPED THE VEHICLE AND THE SPEEDOMETER NEEDLE CONTINUED TO ERRATICALLY GO UP AND DOWN. *TR

• 12/14/2010· FUEL SYSTEM, GASOLINE

  THE FUEL TANK LEVEL SENSOR IS DEFECTIVE AND COULD RESULT IN A SUBJECT VEHICLE RUNNING OUT OF FUEL, STALL, AND BEING REAR ENDED BY ANOTHER VEHICLE. THE FUEL LEVEL SENDING UNIT HAS A VARIABLE RESISTOR ATTACHED TO A FLOAT INSIDE THE FUEL TANK. AS YOU USE FUEL, THE FLOAT CHANGES POSITION (DOWNWARDS) CAUSING THE VARIABLE RESISTOR TO CHANGE VALUE. THE CHANGE IN RESISTANCE CAUSES A CHANGE IN THE VOLTAGE SENT TO THE FUEL GAGE. MY P0463 ERROR IS SAYING THAT THE VARIABLE RESISTOR IS SHOWING HIGH INPUT, INSTEAD OF A TYPICAL SMALL VALUE. THIS MEANS THAT THE VARIABLE RESISTOR OR SOMETHING ELSE INSIDE THE SENDER UNIT IS CAUSING THE ECM TO "SEE" AN INVALID VOLTAGE ON THE FUEL GAGE CIRCUIT. IF THE VOLTAGE IS TOO HIGH THEN THE RESISTANCE IS TOO HIGH. POSSIBLY A BAD CONNECTION BETWEEN THE ECU AND THE SENDER OR A GROUNDING PROBLEM.

  ON THE NIGHT OF SATURDAY (AT 9 P.M.), DECEMBER 10, 2005, I DROVE MY GMC ENVOY SLT TO MICHAEL'S. WHEN DRIVING THROUGH THE PARKING LOT, MY DAUGHTER AND I HEARD A LOUD GRINDING NOISE FROM THE UNDERSIDE OF THE VEHICLE. WE PARKED THE CAR, TURNED OFF THE ENGINE, THEN TURNED THE VEHICLE ON AGAIN. SEVERAL ICONS THAT HAD NEVER BEEN DISPLAYED ON THE DASHBOARD SCREEN APPEARED, AND MY VEHICLE'S CLOCK REFLECTED 12:00. THE CLOCK WAS SET FOR THE CORRECT TIME INITIALLY, AND NEVER TAMPERED . WE SHOPPED FOR 20 MINUTES AND RETURNED TO THE VEHICLE, STARTED IT UP AND AGAIN SEVERAL ICONS APPEARED. THE CLOCK SAID 12:00 THOUGH IT WAS 9:30 P.M. WE DROVE THROUGH OUR NEIGHBORHOOD VIEWING SOME CHRISTMAS LIGHTS FOR ABOUT 10 MINUTES. AS I PULLED ONTO OUR DRIVEWAY AND BEGAN BREAKING TO STOP THE VEHICLE AND AND PARK IT OUTSIDE OF OUR GARAGE, IT DID NOT RESPOND TO BREAKING. WHEN I PUSHED THE BRAKE PEDAL DOWN HARDER, THE VEHICLE CONTINUED AT THE SAME SPEED. I SCREAMED THAT WE WERE GOING TO HIT THE GARAGE DOOR, AND AT THAT MOMENT FELT THE VEHICLE ACCELERATE ALTHOUGH I HAD THE BRAKE PEDAL PUSHED DOWN ALL THE WAY. IT SLAMMED THROUGH THE GARAGE DOOR, I QUICKLY SHIFTED INTO PARK AND SHUT OFF THE ENGINE. MY FRONT AND MY DAUGHTER'S FRONT PASSENGER DOOR COULD NOT BE OPENED AND WE SMELLED GAS. MY HUSBAND CALLED 911 AND EMERGENCY VEHICLES RESPONDED. THEY DETERMINED IT SHOULD BE SAFE BUT ASKED THE FURNACE BE TURNED DOWN SO THAT IT WOULD NOT CAUSE ANY COMBUSTION AND TO KEEP THE AREA VENTILATED.. THE GARAGE DOOR WAS TOTALLY DEMOLISHED, AND DRYWALL DAMAGES IN SEVERAL SPOTS. A TECHNICIAN FROM OVERHEAD GARAGE DOORS REMOVED THE REMNANTS OF THE DOOR. MY DAUGHTER'S CAR HAD MINOR PAINT AND DENT DAMAGE AS IT WAS IN THE GARAGE ALREADY. GM'S ROADSIDE TOWING HAULED THE ENVOY ONTO A FLATBED TO TAKE TO THE DEALERSHIP.

NOVEMBER OF 2006 WE REPLACED THE FUEL SENSOR THAT IS UNDER WARRANTY DUE TO WHEN I WOULD FILL UP THE GAS TANK THE GAUGE WOULD GO TO EMPTY AND WOULD EVENTUALLY MAKE IT TO FULL AFTER ABOUT 100 MILES DRIVEN.

  MY FUEL GAUGE STOPPED WORKING IN MY 2005 ENVOY AT APPROXIMATELY 40,000 MILES. THE FUEL GAUGE INDICATES THAT THE CAR IS OUT OF FUEL AFTER FILL THE TANK FULL. I HAVE NOTICED NUMEROUS COMPLAINTS ABOUT THIS PROBLEM AND HAVE ALSO RECEIVED A LETTER FROM GM STATING THAT THEY ARE AWARE OF THE PROBLEM AND WILL COVER UP TO 50% OF REPAIR AS MY WARRANT HAS EXPIRED. THE PROBLEM WITH ONLY COVERING 50% IS PAYING WITH FOR MY HALF OF THE REPAIR. I HAVE BEEN UNABLE TO COME UP WITH APPROXIMATELY THE $200 FOR THE REPAIR THEREFORE UNABLE TO HAVE IT REPAIRED. I SPOKE WITH GM CUSTOMER SERVICE AND THEY INFORMED ME THAT WAS MY OPTION. WHEN I ASKED WHY THERE HAS NOT BEEN A RECALL ON THE PROBLEM THEY INFORMED ME THAT I SHOULD CONTACT THE NHTSA. MY CONCERN IS THAT I LIVE IN A STATE WITH COLD WEATHER THAT REQUIRES THAT CAR TO WARM UP PRIOR TO DRIVING. SO I WAS KEEPING TRACK OF MY MILEAGE KNOWING WHEN I NEEDED TO FILL UP WITH GAS. ALTHOUGH, THIS WILL NOT BE ACCURATE IN WINTER AND AFRAID THAT MY SPOUSE (PRIMARY DRIVER OF THIS VEHICLE) WILL GET STRANDED ON THE ROAD. I HOPE IF/WHEN THIS HAPPENS IT IS NOT DURING A SNOW STORM WHERE AN AUTO ACCIDENT WILL THEN BECOME LIKELY. WHEN TALKING TO GM ALONG WITH THE FUEL SENSOR I EXPRESSES CONCERNS ABOUT OTHER ISSUES THAT I HAVE BEEN HAVING. FOR EXAMPLE, MY LICENSE PLATE LIGHT STOPPED WORKING, CHANGED THE BULB AND CHECKED THE FUSES AND STILL DOES NOT WORK; ALONG WITH HEAT ISSUES AND WAS INFORMED TO TAKE IN FOR DIAGNOSIS. *TR

  I OWN A 2005 GMC ENVOY THAT IS HAVING A KNOWN PROBLEM WITH THE GAS GAUGE AND THE SENDER UNIT. THE CHECK ENGINE LIGHT ALSO COMES ON. APPARENTLY NUMEROUS CUSTOMERS HAVE BEEN EXPERIENCING THIS SAME ISSUE ON THEIR GM SUVS. THERE SHOULD BE A RECALL TO FIX THESE KNOWN MANUFACTURER FAULTY WORKMANSHIP ISSUES. *TR

  MY VEHICLE WHEN PURCHASED WAS ALTERED FROM CLOTH SEATS TO LEATHER BY THE DEALERSHIP WHERE PURCHASED. 3 DAYS AGO MY CAR IS SIGNALING ME TO SERVICE AIRBAG WHILE DRIVING THE CAR OR IN IDLE. SO I IMMEDIATELY TOOK IT TO A CERTIFIED MECHANIC AT MEINEKE AND WAS TOLD THAT THIS IS A MANUFACTURER DEFECT AND THERE IS A RECALL FOR THIS ON MY YEAR, MAKE & MODEL SUV. I CALLED GM ON 11/29/2019 AND WAS TOLD BY A SUPERVISOR NAMED ANGEL THERE HAS BEEN NO RECALLS BY THEIR MANUFACTURER AND THERE IS NOTHING MORE SHE CAN DO ABOUT THE MATTER. I CANNOT DRIVE MY CAR LIKE THIS KNOWING THIS CAN BE POTENTIALLY HARMFUL AND HAZARDOUS.

  MY 2005 GMC ENVOY HAS STARTED EXPERIENCING A KNOCKING SOUND IN THE RIGHT REAR PASSENGER SIDE. IT STARTS APPROXIMATELY A MINUTE AFTER THE VEHICLE STARTS AND STOPS WITHIN A MINUTE OR SO. IT HAPPENS WHEN THE CAR IS MOVING OR IDLE. THIS STARTED YESTERDAY EVENING. NOT SURE WHAT IS CAUSING IT. EVERYTHING IS RUNNING FINE IN THE VEHICLE. THERE MUST BE OTHER SIMILAR COMPLAINTS AND RESOLUTIONS. *TR
