2004 GMC ENVOY Electrical System Problems

MY 2004 GMC ENVOY SLT CLUSTER GAUGE; SPEEDOMETER, GAS GAUGE, AND OIL PRESSURE GAUGE HAVE STOPPED WORKING. *TR

DEFECTIVE ENVOY SPEEDOMETER. *TR

NOTHING DESCRIPTIVE LED UP TO THE FAILURE. IT HAPPENED FOR NO REASON WE KNOW. THE PROBLEM IS CONSISTENT AND A NEW ONE STARTED TODAY. THE PROBLEM HAS NOT BEEN DIAGNOSED OR FIXED. I FOUND SEVERAL SIMILAR ISSUES ON INTERNET FOR SAME MODEL AND YEAR VEHICLE TODAY AFTER BEING NOTIFIED BY WIFE THAT ANOTHER AREA OF SAME DEVICE HAS MALFUNCTIONED.

SPEEDOMETER WAS ON 80MPS EVERYTIME I STARTED THE CAR, I WOULD TURN THE MOTOR OFF SEVER TIMES TO BRING IT DOWN ABOUT 5MPS, UNTIL THAT QUITE WORKING COMPLETELY. MY SISTER-IN-LAW HAD THE SAME PROBLEM WITH HERS AT THE SAME TIME I DID. WELL, I WENT TO GET MY FIXED THEY SAID IT WASN'T COVERED UNDER A WARRENTY AND THE COST WAS HIGH AT THE TIME SO I HAD TO BARROW A GPS SYSTEM TO USE TO CLOCK MY SPEED. THEN THE GAS GAUGE WENT OUT. WOULD HAVE TO WAIT UNTIL MY GAS LIGHT CAME ON TO LET ME KNOW WHEN I WAS RUNNING LOWAND WHEN I WOULD PUT GAS IN MY CAR, I WOULD HAVE TO TRY AND START IT 3-4 TIMES BEFORE IT WOULD START. MY CAR IS IN THE SHOP TODAY, AND AFTER ALOT OF RESEARCH I NOTICE ALOT OF PEOPLE HAVE THE SAME PROBLEM, AND GMC DOES...

MY WIFE HAS A 2004 GMC ENVOY,ABOUT 6:00 MAR 03 2010 SHE CALLED ME FROM HER TRUCK, SAYING THE ODOMETER SAID SHE WAS DOING 95 MPH WHEN SHE WAS ONLY DOING ABOUT 55MPH AFTER I GOT HER TO CALM DOWN AND PULL OVER. SHE STOP THE TRUCK AND WAITED ON ME TO GET THERE. I NOTICE THE RPM'S WAS STUCK ON 6000 THE GAS WAS ON A 1/4 TANK AFTER SHE SAID SHE HAD PUT 40$ IN THE TANK 30MIN AGO PLUS THE CLOCK SAID 12:49 AND IT WAS LIKE 7:00 AFTER TALKING TO A FEW PEOPLE FOUND OUT THERE WAS WITH THE CLUSTER. WAS TALKING TO MY FATHER WHO HAS A 05 GMC TRUCK SAID THERE WAS A RECALL ON THE CLUSTERS. *TR

RIGHT AFTER PURCHASING. ENGINE LIGHT HAS BEEN ON. PURCHASED IN JUNE/2006, WITH 40,000MILES. 1YR AFTER THE RPM GAUGE QUIT WORKING, RIGHT AFTERWARDS,THE FUEL GAUGE STARTED MESSING UP, GOING BACK & FORTH,THEN WENT OUT COMPLETELY, BATTERY/OIL GAUGES ARE OUT NOW. THE SEAT BELT LIGHTS/AIRBAG LIGHTS BING CONSTANTLY & DOES NOT TIGHTEN UP WHEN PUT ON BRAKES. WHEN THIS HAPPENS THE CHECK GAUGES LIGHT COMES ON, AND AT THE SAME TIME I HAVE DIFFICULTY GETTING IT IN GEAR. I AM ALSO HAVING TROUBLE SETTING MY CRUISE CONTROL. *TR

DURING NORMAL HIGHWAY DRIVING, THE INSTRUMENTATION PANEL NEEDLE GAUGES BEGAN TO MALFUNCTION. THE SPEEDOMETER INITIALLY REGISTERED SIGNIFICANTLY HIGHER THAN ACTUAL SPEEDS (REGISTERED 110+ MPH WHEN TRAVELING AT ~65 MPH) AND THEN STUCK AT 15 MPH REGARDLESS OF ACTUAL SPEED OR WHEN AT A COMPLETE STOP. THE TACHOMETER ALSO BEGAN TO REGISTER HIGHER THAN ACTUAL RPM, SHOWING 6,000+ RPM EVEN WHEN THE VEHICLES ENGINE WAS RETURNED TO IDLE OR TURNED OFF. OTHER GAUGE MALFUNCTIONS INCLUDE THE OIL PRESSURE GAUGE WHICH WOULD ALSO INTERMITTENTLY REGISTER HIGHER THAN ACTUAL PRESSURE. WITHOUT EITHER A FUNCTIONING SPEEDOMETER OR TACHOMETER, IT IS VERY DIFFICULT TO ESTIMATE ACTUAL VEHICLE SPEEDS AND MAINTAIN A SAFE DRIVING SPEEDS. HAVE CONTACTED A LOCAL GMC DEALER REGARDING THIS ISSUE AND HAVE NOT YET IDENTIFIED A REMEDY. *TR

I PURCHASED A 2004 ENVOY OFF THE SHOWROOM FLOOR. FIRST ISSUE WAS AN ERRATIC SPEEDOMETER, THEN NON-WORKING GAS GAUGE, NOW IT IS ALL GAUGES. I HAVE A PICTURE WITH THE CAR IN PARK SHOWING 15 MPH, THE DIGITAL READING SHOWS A FULL TANK OF GAS BUT THE GAUGE NEEDLE IS BELOW EMPTY AND ALSO NO OIL PRESSURE OR TEMPERATURE. THE ENTIRE CLUSTER IS FAULTY, NOT JUST ONE GAUGE. *TR

ENVOY XUV 2004 OIL PRESSURE STALLED 80 OR HIGHER. GM HAS A TSB REGARDING ISSUES WITH THE CLUSTERS #07187, BUT THEY ARE NOT ACCEPTING THAT THE ENVOY ALSO HAS THE SAME PROBLEMS. DEALERS WANT TO CHARGE AROUND $500 TO $1000 TO FIX THIS PROBLEM WHICH THEY KNOW IS HAPPENING ON MANY MODELS. *TR

SPEEDOMETER DOES NOT WORK ACCURATELY. CHECK ENGINE LIGHT CAME ON RANDOMLY. IS CURRENTLY OUT AND I WAS ABLE TO PASS EMISSIONS, HOPEFULLY IT WILL REMAIN OUT. HAD TO REPLACE MANY PARTS INCLUDING THE HEATER CORE, THERMOSTAT AND COOLANT. NOW I AM EXPERIENCING A PROBLEM WITH THE FAN OF THE CAR. *TR

SPEEDOMETER ON 2004 GMC ENVOY SLT QUIT WORKING. I FOUND THAT THIS IS A VERY COMMON PROBLEM WITH GM VEHICLES, HOWEVER THEY HAVE NOT ISSUED A RECALL FOR IT. I FEEL THAT THIS COULD BE A HUGE SAFETY ISSUE AND THAT THEY ARE AWARE OF IT BUT CONTINUE TO IGNORE COMPLAINTS. KNOWING YOUR SPEED IS EXTREMELY IMPORTANT WHEN DRIVING. *TR

INSTRUMENT PANEL CLUSTER ISSUES. DRIVER 1 RESETS TO UNKNOWN DRIVER, ABS LIGHT, SEATBELT LIGHT, 4-WHEEL DRIVE, ETC. LIGHTS FLASH ON AND OFF, BATTERY GAGE FLUCTUATES, HEADLIGHTS AND INSTRUMENT PANEL LIGHTS FLICKER DIM TO BRIGHT. OCCURS WHILE DRIVING DOWN THE ROAD VERY SPORADIC. DIAGNOSTIC STATED FAULTY INSTRUMENT PANEL CLUSTER. ISSUE IF NOT FIXED, THE VEHICLE COULD STALL WHEN DRIVING AND LOSE POWER. *TR

I PURCHASED A USED 2004 GMC ENVOY SLT, WITH AN EXTENDED WARRANTY FROM GRAND PRIX AUTO GROUP, HICKSVILLE, NY IN AUGUST 2008. SOON AFTER PURCHASING THE CAR IT STALLED WHILE WE WERE AT A RED LIGHT. IMMEDIATELY BROUGHT THE TRUCK BACK TO THE DEALER AND THEY SAID THEY FIXED IT, MAY I MENTION IT NEVER STOPPED STALLING. THEN THE SPEEDOMETER BROKE AGAIN. IT CONSTANTLY SAYS I'M TRAVELING 120 MILES AN HOUR. ONCE AGAIN, BROUGHT IT BACK TO THE DEALER, THEY TELL ME I NEED TO GO TO A GMC DEALER, I DO, THEY REPLACE THE INFORMATION CLUSTER AND SPEEDOMETER, HAD TO PAY A $ 300.00 DEDUCTIBLE. THIS WAS IN MARCH 2009. DRIVING THE OTHER DAY OCTOBER 2009 AND THE SPEEDOMETER ONCE AGAIN SAYS 120. GET PULLED OVER, GET A TICKET FOR A BROKEN SPEEDOMETER. THE OFFICER WAS AWARE I WAS NOT TRAVELING AT THAT SPEED, AND EVEN WHEN I TRIED...

ON A 2004 GMC ENVOY, THE WHOLE ODOMETER/SPEEDOMETER WENT OUT. NOTHING WORKED AND I HAD TO GET MY WHOLE INSTRUMENT CLUSTER REPLACED. *TR

2004 GMC ENVOY INSTRUMENT PANEL CLUSTER SUDDENLY STARTED NOT WORKING. IT HASN'T WORKED PROPERLY SINCE IT HAPPENED AND READS INCORRECT SPEED, OIL PRESSURE, AND FUEL LEVELS. NOTHING HAS BEEN DONE TO CORRECT THE FAILURE BY THE DEALER. *TR

THE SPEEDOMETER ON MY 2004 ENVOY HAS BEEN INACCURATE AT LEAST 5 TIMES IN THE LAST 9 MONTHS. I NOTICED THAT THIS PROBLEM ARISES WHEN THERE IS A SPIKE OR DIP IN TEMPERATURE OUTDOORS. FOR OVER 24 HOURS THE SPEEDOMETER WAS STUCK AT 120 MPH. THE SPEEDOMETER CORRECTS ITSELF OVER THE COURSE OF 4 OR 5 DAYS DEPENDING ON HOW MANY STARTS AND STOPS I MAKE AROUND TOWN. I SEE THAT GM ISN'T GOING TO CLAIM ANY RESPONSIBILITY ON THIS MATTER SO I JUST PAY VERY CLOSE ATTENTION TO MY SPEEDOMETER WHEN DRIVING AND STAY IN THE SLOW LANE. CAN'T AFFORD TO PAY THE BIG BUCKS FOR THEIR MISTAKE. *TR

I HAVE 2004 ENVOY HAVE HAD PROBLEMS WITH ALTERNATOR. STARTED ABOUT 6 MONTHS AFTER I BOUGHT THE ENVOY HAD I REPLACED 3 TIMES THEN STARTED HAVING PROBLEMS WITH BACK SEAT WINDOW ON PASSENGER SIDE NOT ROLLING UP. THEN MY GIRLFRIEND HAD A FLAT ON SIDE OF ROAD AND COULD NOT GET SPARE DOWN I HAD TO GO OUT AND CUT THE CABLE THAT HOLDS IT UP. THAT IS A UNSAFE THING TO DO ON SIDE OF HWY SHOULD NOT TAKE 45 MIN TO GET SPARE DOWN. HEADLIGHTS DIM AND BRIGHTEN GETS DIM ENOUGH THAT MAKES HARD TO SEE. *TR

WHEN TRAVELING DOWN THE ROAD AND PUTTING ON THE BRAKES THE HEADLIGHTS AND DASH LIGHTS FLICKER. THE FLICKERING IS SO MUCH THAT IS LOOKS LIKE WE ARE FLASHING OTHER CARS. *TR

MY 2004 GMC ENVOY HAS DEVELOPED AN ERRATIC SPEEDOMETER. THE SPEEDOMETER REFLECTS INACCURATE SPEEDS CAUSING AN UNSAFE DRIVING CONDITION. I CONTACTED MY LOCAL GMC DEALER WHO RESEARCHED TO FIND NO RECALL CONCERNING THIS PROBLEM I THEN SUBMITTED MY COMPLAINT TO THE BBB HOTLINE AND WAS REBUFFED THEIR ALSO. I HAVE CONSEQUENTLY DONE ADDITIONAL RESEARCH AND HAVE FOUND THAT GM HAS ISSUED A SPECIAL COVERAGE ADJUSTMENT BULLETIN FOR 2003-2004 CADILLAC ESCALADE, CHEVROLET AVALANCHE, SILVERADO, SUBURBAN AND TAHOE, GMC SIERRA AND YUKONS. THE SPEEDOMETER UNIT IN THESE MODELS ARE VERY SIMILAR IN BOTH APPEARANCE AND ARE MANUFACTURED BY THE SAME SUPPLIER GM USES. THE ADJUST BULLETIN IS #07187 DATED SEPTEMBER 28,2007 AND COVERS THE CONDITION FOR A PERIOD OF 7 YEARS OR 70,000 MILES REGARDLESS OF OWNERSHIP. AFTER VISITING MANY GMC AND CHEVROLET CHAT ROOMS IT IS READILY APPARENT THAT THIS PROBLEM IS VERY COMMON AND WILL EVENTUALLY RESULT IN A FATAL...

PROBLEM STARTED OUT AS ERRATIC READING WITH SPEEDOMETER. AFTER APPROX. 5 DAYS SPEEDO FINALLY WOULDN'T REGISTER AT ALL TOOK VEHICLE TO AUTHORIZED DEALER TO BE REPAIRED - $555.00 CHARGE TO REPLACE INSTRUMENT PANEL AND REPROGRAM. CALLED GM FOR FINANCIAL HELP AS I NOTICED THERE WERE ALOT OF FAILURES WITH GMC SUV'S AND PICK-UP TRUCKS. GM WOULD NOT ACKNOWLEDGE THERE WAS A PROBLEM WHICH I FEEL IS TOTALLY DISINGENUOUS. SPEEDOMETER IS NECESSARY TO BE WORKING AS A SAFETY ISSUE. BECAUSE I WAS OUT OF STATE AT THE TIME OF PART BREAKDOWN I FELT I HAD NO CHOICE BUT TO HAVE PROBLEM FIXED BEFORE MY RETURN TRIP HOME (1250 MILES). JUDGING HOW MANY OTHER ENVOYS HAVE HAD SAME PROBLEM, I FEEL GM IS DODGING THEIR RESPONSIBILITY I NOTICED THAT THERE HAS BEEN CLASS-ACTIONS AGAINST THEM FOR THE SAME PROBLEM. *TR

THE SPEEDOMETER GRADUALLY DECREASED FROM INTERSTATE SPEED (70MPH) TO 0 MPH WHILE DRIVING. SPEEDOMETER FAILS TO OPERATE. I PERSONALLY KNOW 2 PEOPLE WHO HAVE HAD THIS HAPPEN ON A 2004 ENVOY. *TR

THE TACH ON MY '04 ENVOY WITH 67K MILES STARTED ACTING ERRATIC AND HAS COMPLETELY FAILED JUST AS ALL THE OTHER SERVICE BULLETINS . THIS HAS CORRECTED ITSELF BUIS TILL ERRATIC. GM NEEDS TO ADDRESS THE FAULTY ELECTRONIC GAUGES ON THESE '04 ENVOYS. *TR

INSTRUMENT CLUSTER. SPEED ODOMETER AND TACH NOT ACCURATE. I HAVE HAD 2 SPEEDING TICKETS BECAUSE I DON'T KNOW HOW FAST I AM GOING. NOT SURE OF THE DATE IT FIRST HAPPENED BUT IT IS GETTING WORSE. GM DEALER IN MY AREA WAS RUDE TO MY WIFE AND SAID THEY WILL NOT COVER IT. *TR

I BEGAN EXPERIENCING PROBLEMS WITH THE INSTRUMENT PANEL ON MY 2004 GMC ENVOY A FEW MONTHS AGO. THE ENTIRE PANEL WOULD GO OUT AND ALL THE GAUGES BOTTOMED OUT. I COULD NOT TELL MY SPEED, GAS LEVEL, RPMS, ETC. THE PANEL WOULD STAY OUT FOR A FEW DAYS THEN RETURN TO NORMAL. ALSO ON OCCASION THE SPEEDOMETER WOULD STICK AT 60 MPH AND ONLY CORRECT ITSELF IF I PULLED OVER AND TURNED THE TRUCK OFF THEN BACK ON. FINALLY, ABOUT TWO WEEKS AGO THE ENTIRE INSTRUMENT PANEL WENT OUT AND HAS NEVER COME BACK ON. I HAVE DROPPED IT OFF AT THE DEALERSHIP FOR SERVICE AND AM AWAITING THEIR RESPONSE. THIS PROBLEM HAS CAUSED ME TO RUN OUT OF GAS TWICE BECAUSE I WAS UNABLE TO JUDGE MY FUEL LEVEL. LUCKILY BOTH TIMES I WAS IN AN AREA WITH EASY ACCESS TO THE SHOULDER OF THE ROAD. I CURRENTLY HAVE...

TL*THE CONTACT OWNS A 2004 GMC ENVOY. WHILE DRVING 20 MPH THE SPEEDOMETER STOPPED WORKING. THE DEALER STATED THAT THEY ASSUMED IT WAS A PART OF THE MANUFACTURERS RECALL AND REPAIRED THE VEHICLE. THE DEALER CONFIRMED AFTER THE REPAIRS WERE MADE THAT THE VEHCLE WAS NOT WITHIN THE RECALL VIN RANGE. THE DEALER HAS BILLED THE CONTACT FOR THE REPAIRS. THE FAILURE MILEAGE WAS 52,000 AND THE CURRENT MILEAGE WAS 55,000.

SPEEDOMETER MALFUCTIONS. *TR

I HAVE A 2004 GMC ENVOY IN WHICH THE SPEEDOMETER HAS STOPPED WORKING. I RESEARCHED THIS ON THE INTERNET AND IT IS A COMMON OCCURRENCE. I ALMOST CAUSED A WRECK BECAUSE THE SPEEDOMETER SAID I WAS GOING FASTER THAN I REALLY WAS AND THE CARS BEHIND ME ALMOST RAN INTO ME. THIS IS A SAFETY ISSUE THAT I FEEL SHOULD BE INVESTIGATED. COULD YOU PLEASE ASSIST W ANY RECALL MEASURES. IT COSTS OVER 500.00 TO REPLACE THIS. *TR

THIS PAST MONTH THE SPEEDOMETER SET AT 40 MPH WITH CAR IN "PARK" POSITION. AFTERWARD WHEN DRIVING, MY ACTUAL SPEED HAD 40MPH ADDED TO THE READING. THIS HAS OCCURRED THREE TIMES SO FAR IN OCTOBER 2008. *TR

MY 2004 GMC ENVOY MPH AND RPM GAUGES ARE NOT WORKING PROPERLY, I CALLED THE DEALERSHIP AND AN EXTENDED WARRANTY WAS PUT ON ALL GMC/CHEVY TRUCKS AND SUV FOR THE DASHBOARD CLUSTER EXCEPT FOR THE ENVOY, ANY NEWER MODELS. THE PART IS AT LEAST 500 AND ADVISED CAN ONLY BE DONE BY DEALERSHIP DUE TO PROGRAMMING. IM FURIOUS, MY TRUCK IS ONLY AT ABOUT 53,000 MILES. THIS DEFECT NEEDS TO BE UNDER RECALL FOR THE ENVOY ASAP! *TR

DRIVING AT SLOW SPEED AND NOTICED SPEEDOMETER WAS READING INCORRECTLY--MUCH HIGHER THAN ACTUAL. VEHICLE DRIVEN SEVERAL TIMES SINCE, WITH CONTINUED INCORRECT SPEED RATING. ALL ORIGINAL EQUIPMENT AT 68,000 MILES WITH NO PREVIOUS REPAIR NOTED. *TR

SPEEDOMETER STOPPED WORKING. *TR

1. I PURCHASED A 2004 ENVOY. THE DEALER I PURCHASED IT FROM HAD IT UNDER WARRANTY. 2 WEEKS AFTER I PURCHASED, THE INTERIOR LIGHTS WERE COMING ON AND OFF, THE AUTOMATIC DOOR LOCKS STARTED TO LOCK BY THEMSELVES SIMULTANEOUSLY. NON STOP. IT SCARES MY CHILDREN, AS WELL AS I, BECAUSE I DON'T KNOW IF IT'S GOING TO SPARK A FIRE OR WHAT. SOMETIMES IT DOES IT MORE THAN OTHERS, FOR EXAMPLE, WHEN IT RAINS, BUT IT ONLY DOES IT WHEN I ROLL THE DRIVER'S SIDE WINDOW UP. EVEN IF ITS NOT DOWN AND I ROLL IT UP IT DOES IT. AS WELL AS IF I HIT A SMALL POT HOLE AND SOMETIMES IT JUST DOES IT ON ITS ON. I'VE TAKEN IT TO A GMC DEALER 4 OR MORE TIMES AND THEY CAN'T FIND THE PROBLEM ANY WHERE. SO, NOTHING HAS BEEN DONE TO FIX THIS PROBLEM BECAUSE NO ONE...

THE MPH AND RPM GAUGES NOT WORKING. I CAN BE SITTING AT A STOP LIGHT AND IT SHOWS MY 2004 ENVOY IS GOING 70 MPH. ALSO THE RPM GAUGE WILL SAY 0 RPMS WHEN I AM GOING AT ANY SPEED. WE HAVE REPEATEDLY DISCONNECTED THE POSITIVE CABLE TO RESET THE GAUGES. I AM AFRAID I WILL GET PULLED OVER BECAUSE I HAVE NO IDEA WHAT SPEED I AM GOING. HAS ANYONE ELSE HAD THIS PROBLEM? *NM

I HAVE BEEN EXPERIENCING HEADLIGHTS, INTERIOR LIGHTS, LIGHTING IN THE DASH, AND OTHER LIGHTING FLICKER WHILE DRIVING. IT APPEARS TO BE HAPPENING MORE AND MORE. THE LIGHTS BECOME VERY DIM AND THEN GET BRIGHT AGAIN IN A MATTER OF A FEW SECONDS. THIS IS GETTING TO BE DANGEROUS AS PEOPLE TEND TO PULL OVER IN FRONT OF ME AND SOMETIMES TRAFFIC IN GOING IN THE OPPOSITE DIRECTION COMING TOWARDS ME WILL PULL OF THE ROAD ALL THINKING THAT I AM FLASHING THEM EITHER DUE TO AN EMERGENCY OR JUST SOME WILD DRIVER BEHIND THE WHEEL. I HAD TAKEN MY VEHICLE TO THE DEALER BUT HE STATES HE CAN NOT FIND ANYTHING WRONG. OF COURSE HE ALSO STATED THEY TOOK IT FOR A RIDE BUT IT DOES NOT HAPPEN FOR THEM. I GUESS NOT, IT IS HARD TO SEE LIGHTS FLICKERING IN THE SUNSHINE. *NM

DT*: THE CONTACT STATED WHILE EXITING THE OFF-RAMP OF THE HIGHWAY AT 20-25MPH, THE CHECK ENGINE AND REDUCED POWER LIGHT ILLUMINATED AND THERE WAS A LOSS OF ALL VEHICLE POWER. ALTHOUGH THE ENGINE RESTARTED AFTER SEVERAL ATTEMPTS, THE VEHICLE WAS TOWED TO THE DEALER FOR INSPECTION. THE DEALER DETERMINED THE ACCELERATOR SENSOR NEEDED TO BE REPLACED. AFTERWARDS, THE LOSS OF POWER PERSISTED AND THE ACCELERATOR SENSOR WAS AGAIN REPLACED BY THE DEALER AS WELL AS THE COMPUTER. ADDITIONALLY, THE HORN INTERMITTENTLY WORKED, BUT THE HORN WAS NOT INSPECTED.

I BOUGHT MY GMC ENVOY IN JANUARY 2004 FOR APPROX. $42,000. THIS CAR HAS EVERYTHING. AFTER ABOUT 2 MONTHS OF THE PURCHASE, MY GPS WENT OUT AND HAD BEEN FIXED TWICE. MY BRAKES DO NOT ALWAYS WORK --SOMETIMES THEY SLIP ESPECIALLY WHEN I NEED THEM MOST -WHICH IS SCARY. GMC SAID THAT THEY HAVE HEARD ABOUT THIS PROBLEM BEFORE, BUT DID NOTHING TO RESOLVE THE PROBLEM. THE ENGINE STALLS PERIODICALLY. GMC SAID THEY DO NOT KNOW WHY. THE GAS GAUGE AND ODOMETER DO NOT WORK PROPERLY. WHEN I BROUGHT MY VEHICLE INTO NORTH COUNTY GMC DEALERSHIP IN SAN DIEGO FOR REPAIRS I MENTIONED MY GAS GAUGE DID NOT WORK ALONG WITH MANY OF THE OTHER ISSUES. AFTER THEY REPAIRED THE ODOMETER BY REPLACING THE CLUSTER, THE GAS GAUGE STILL DID NOT WORK. EVERY SINGLE TIME THESE PROBLEMS HAPPEN I AM FORCED TO PAY A $100 SERVICE CHARGE JUST SO THEY...

FIRST OF ALL MY ODOMETER GAUGE STOPPED OPERATING. IT REMAINED ON ZERO MILES WHILE I WAS DRIVING THE VEHICLE SINCE NOVEMBER 2005. THE WHOLE DASHBOARD CLUSTER HAD TO BE REINSTALLED. SECONDLY; THE SERVICE ENGINE SOON LIGHT BEGAN POPPING ON AND THE ENVOY WAS DRIVING ROUGH. I FOUND OUT FROM A GM DEALER THAT THE CLUTCH FAN FROZE WHICH CAUSED THE WATER PUMP TO BREAK AND THE RADIATOR TO OVER HEAT BURST THE RADIATOR HOSE AND SPEW OUT AND LEAK ALL OF THE WATER AND RADIATOR FLUID FROM THE RADIATOR. THE ENVOY IS NOW NOT DRIVABLE. I HAVE ONLY HAD THIS 2004 ENVOY SINCE NOVEMBER OF 2003. *NM

HEADLIGHTS, DRIVING LIGHTS AND ALL INTERIOR LIGHTING DIM AND FLICKER APPROX EVERY 30 SECONDS. HAS BEEN THIS WAY FOR OVER 10 DAYS, DEALER CANNOT DIAGNOSE PROBLEM UNTIL THE "SERVICE ENGINE SOON" LIGHT COMES ON, WHICH IT HASN'T. IT IS NEARLY IMPOSSIBLE TO DRIVE AT NIGHT WITH DIM, FLASHING, HEADLIGHTS, AND IS CONFUSING TO OTHER DRIVERS. ALSO, A FAN CAN BE HEARD BLOWING OFF & ON APPROX ONCE EVERY MINUTE, AND THIS IS WITH THE VEHICLE COMPLETELY TURNED OFF AND THE KEY OUT OF THE IGNITION. THIS IS CONSTANT, I'M CONCERNED THE BATTERY WILL BE DEAD AND THE CAR WON'T START, OR THAT THE LIGHTS WILL COMPLETELY GO OUT WHILE I AM DRIVING AT NIGHT. REAR PASSENGER DOOR LOCKS SUDDENLY STOPPED WORKING WITH THE REMOTE AND THE DOOR UNLOCK SWITCH ON THE DRIVER'S DOOR. I HAVE TO CLIMB OVER THE FRONT SEAT INTO THE BACK TO PHYSICALLY UNLOCK THE DOOR TO...

2004 GMC ENVOY DEVELOPED THE FOLLOWING PROBLEMS: VEHICLE STALLED, TURN SIGNALS STOPPED WORKING, BLOWER FAN STOPPED WORKING, AND THE SRS LIGHT REMAINS LIT.*MR THE TURN SIGANLS STOPPED WORKING DUE TO A SHORT IN THE FLASHER. THE POWERTRAIN CONTROL MODULE WAS REPLACED DUE TO THE SES LIGHT ILUMINATING. THE BLOWER MOTOR FAN FAILED 4 TIMES DUE TO A SHORT IN THE WIRES AND CONTROL HEAD. THE VEHICLE OVERHEATED, BUT THE PROBLEM COULD NOT BE DIAGNOSED. THE LCD DISPLAYS, KNOBS BECOME EXTREMLY HOT AFTER HOURS OF DRIVING. *JB

I OWN A 2004 ENVOY. I HAD TAKEN THE VEHICLE IN FOR SERVICE PREVIOUSLY FOR ELECTRICAL ISSUES. THE HEADLIGHT AND INTERIOR LIGHTS WOULD CONSTANTLY FLICKER AS YOU DROVE. THE DRIVERS DOOR ALSO LOCKED ITSELF WHEN EXITING THE VEHICLE. THE PROBLEMS WERE INTERMITTENT, HAPPENING ABOUT 3 TO 4 TIMES A MONTH. SINCE THE PROBLEMS PERSISTED, I AGAIN TOOK THE VEHICLE FOR SERVICE. ANOTHER ELECTRICAL PROBLEM HAD ARISEN ALSO. THE HORN, AT TIMES, WOULD NOT WORK. AGAIN THIS WAS AN INTERMITTENT PROBLEM. THE DEALER SAID THEY COULD NOT LOCATE THE PROBLEM UNLESS IT WAS OCCURRING WHEN THEY HAD THEY WERE CHECKING IT. I CALLED GM CUSTOMER ASSISTANCE TO FILE A COMPLAINT. THEY THEN TALKED WITH THE DEALER. THE CAR WAS KEPT FOR SEVERAL MORE DAYS AND RETURNED WITH THE DIAGNOSIS THAT THE PROBLEM COULD NOT BE LOCATED SINCE IT WAS NOT OCCURRING WHEN THEY HAD THE VEHICLE. THEY DID NOTE THAT THE...

WHILE DRIVING AT ANY SPEED CHECK ENGINE LIGHT APPEARED ON THE DASHBOARD AND REMAINEDED ON. VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION, AND MECHANIC DETERMINED THAT THE COMPUTER NEEDED TO BE REPLACED, AND REPLACED IT. HOWEVER, THE PROBLEM RECURRED. *AK
