2004 GMC Envoy Electrical System Problems

The contact owns a 2004 GMC Envoy. The contact stated that while the vehicle was parked and unoccupied, the contact noticed that the front passenger's door was on fire. The contact stated that he arrived home just in time and noticed the fire. The contact stated that, because it was raining, the contact's wife had powered the window up; however, the contact noticed that the window was down when the fire occurred. In addition, the contact stated that the fire was blazing, and after the fire was extinguished, the smoke was still visible. The contact extinguished the fire. The contact disconnected the battery. In addition, the contact stated that it could have been a huge fire because the fuel tank had just been refilled prior to the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 133,295.

Headlight's,taillight's,turn signals stop working whenever they want.It's pretty scary to lose your headlight's when your driving at night.There's nothing i can do about it,except to sit wherever it happend and wait for them to come back on.My wife was following me one day and told me my brakelight's and turn signal stopped working and started to work again,she said this happened a couple time's at the same red light.There a couple of thing's (electrical)inside the vehicle that don't work anymore but i really dont care about them.To get the odometer to work i have to knock pretty hard on the plastic cover that cover's the instrument cluster,sometimes it stay's on,most of the time it wont stay on.The DIC (driver control center) doesn't work anymore.I cant even get to it.The speakers on the left side of the vehicle dont work anymore.I thought i would tell you about the inside also because it could be part of the problem.All of this happened when i was driving home from my daughter's two night's ago.I bought this vehicle about three or four's year's ago,and i had no problem's with it untill the other night.The person i bought it from is a good friend of mine.He said he never had a problem with it,plus i have been in this vehicle countless times,that's why i bought it. Thank you.

MY DASH PANEL GAUGES BEGAN FAILING ONE BY ONE. MY HEADLIGHTS WILL SOMETIMES NOT COME ON AFTER STARTING THE CAR WITH THE HEADLIGHT SWITCH ON AUTO. A FLICK OF THE HEADLIGHT SWITCH IN AND OFF, DOES NOT MAKE THE HEADLIGHTS COME ON. SOMETIMES THEY COME ON AFTER DRIVING AROUND, AND THEN WILL GO OFF WITHOUT TOUCHING THE SWITCH. NOW, MY SIDE BRAKELIGHTS WILL NOT OPERATE CORRECTLY WHEN THE BRAKE PEDAL IS PRESSED. ONLY THE THIRD BRAKE LIGHT ILLUMINATES.

FRONT PASSENGER SEAT CAUGHT ON FIRE FROM THE SEAT HEATER. THE VEHICLE PARKED AND TURNED OFF. IT WAS PARKED IN A HIGH SCHOOL PARKING LOT WHILE MY DAUGHTER WAS IN SCHOOL. WE CONTACTED GMC, BUT THEY SAID IT THERE WAS NOTHING THEY COULD DO. THERE WAS SOMETHING THAT WENT WRONG FOR IT TO JUST CATCH FIRE. CAN YOU HELP US IN ANYWAY AT ALL.

TL* THE CONTACT OWNS A 2004 GMC ENVOY. WHILE THE VEHICLE WAS PARKED, THE TAILGATE LATCH AND MOTOR FAILED. AN INDEPENDENT MECHANIC DIAGNOSED THAT THE TAILGATE MOTOR FAILED AND NEEDED TO BE REPLACED. THE CONTACT ALSO STATED THAT THE AIR COMPRESSOR FAILED TO INFLATE THE AIR BAGS EVENLY. THE VEHICLE WAS TAKEN TO W-K CHEVROLET BUICK GMC CADILLAC (LOCATED AT 3310 W BROADWAY BLVD, SEDALIA, MO 65301, (660) 826-8320), BUT WAS NOT DIAGNOSED OR REPAIRED. THE CONTACT WAS INFORMED THAT THE VIN WAS NOT INCLUDED IN A RECALL. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS UNKNOWN.

THE ABS LIGHT STAYED ON AFTER THE FACT I HAD THE BREAKS SERVICED A FEW YEARS AGO. THE AIRBAG LIGHT HAS BEEN ON FOR ABOUT A YEAR. NOW MY BREAK LIGHT STOPPED WORKING, I REPLACED THE FUSE AND STILL NOT WORKING AND NOW THE HEADLAMPS STOPPED WORKING. THEY ONLY WORK ON HIGH BEAM.

TL* THE CONTACT OWNS A 2004 GMC ENVOY. THE CONTACT STATED THAT THE VEHICLE'S ELECTRICAL SYSTEM STOPPED THE VEHICLE FROM STARTING. THERE WERE UNKNOWN WARNING INDICATORS ILLUMINATED AT THE TIME OF THE FAILURE. THE VEHICLE WAS TOWED MULTIPLE TIMES DUE TO FAILING TO START. AN INDEPENDENT MECHANIC STATED THAT THERE WAS A CABLE DISCONNECTED, BUT THE VEHICLE WAS NOT REPAIRED. THE FAILURE OCCURRED AGAIN AND THE VEHICLE WAS TAKEN TO JESSUP AUTO PLAZA (68-111 E PALM CANYON DR, CATHEDRAL CITY, CA 92234, (760) 328-9999). THE TECHNICIAN WAS UNABLE TO LOCATE A FAILURE AND THE VEHICLE WAS RESTARTED. THE VEHICLE WAS NOT REPAIRED AND THE FAILURE OCCURRED AGAIN. THE MANUFACTURER WAS NOT CONTACTED. THE FAILURE MILEAGE WAS 72,338.

I WAS IN THE HIGHWAY TAIL LIGHTS WEREN'T WORKING IN WAS HEADED TO IDAHO DUE TO THAT IM STILL IN NORTH DAKOTA ALSO LIKE A MONTH AGO I WAS PULLED OVER IN THE CITY FOR NO BACK LIGHTS IT'S HAPPEN 4 OR 5 TIMES TWO ON A 15 HOUR ROAD TRIP.TAILGATE HAS OPEN TWICE ONCE IN CITY AND ON HIGHWAY NOW IT DOESN'T SHUT AT ALL ITS BEEN LIKE THAT FOR 5 MONTHS NOW AND IT STARTED TO NOT WANT TO OPEN OR CLOSE THE ROOF PART AS WELL IT SOUND AS IF ITS JAM.I WORRY ABOUT MY SAFETY AND PUBLIC AS WELL. JUST PAID OVER 2400.00 FOR REBUILDING TRANY,POWER STEERING,AND MY GEAR SHIFT AS WELL IT WOULD NOT SHIFT IT SNAP OFF.TRANSMISSION WENT OUT 6 HOURS BEFORE I GOT TO MY DESTINATION.IT WAS TOWED TO A TRANY SHOP AROUND NOV.12/2015 PICKED UP FEB.23/2016 HOPING THEY WOULD FIX ALL THE REST OF DEFECTS IT HAS. YOU NAME IT THIS ENVOY HAS IT OR HAS HAD IT FROM HEADLIGHTS BULB BEING REPLACED EVERY SO OFTEN AND MELTING WERE LIGHT BULB GOES, A/C AND HEATER DON'T WORK PROPERLY DRIVER SIDE IS HOT AND PASSENGER COLD OR VICE-VERSA. THE PASSENGER BACK SIT I WOULD NOT KNOW.MIDWINDOW DOESN'T WORK IT DOESN'T ROLL UP OR DOWN OR THAT LATCH THAT COMES DOWN TO HAUL STUFF AS WELL IT DOESN'T WORK. WHEN I ROLL MY POWER WINDOWS MY HEADLIGHT AND ENGINE IDLE POWERS GOES DOWN AS IF THERE IS AN ELECTRICAL PROBLEM.I'VE INVESTED ON THIS ENVOY A WEEK LATER WHEN I DROVE IT OUT OF THE YARD. I HAVE ALL MY RECEIPTS FROM PROFESSIONAL MECHANICS.ITS BEEN A BAD EXPERIENCE.I HOPE MY TRANY DOESN'T GO OUT AFTER I'M DONE FIX ALL THIS OTHER PROBLEMS. I READ AFTER SOMEONE HAD REBUILD THE TRANY 13 MONTHS LATER HE HAD THE SAME PROBLEM AGAIN WITH HIS ENVOY. IT'S NOT SAFE TO OPERATE A VEHICLE WITH SO MANY ISSUES ESPECIALY WITH NO BACK LIGHTS GOING FROM GOOD TO NOT WORKING.EVERY TIME I HAVE TO BE CHECKING IF I HAVE MY REAR LIGHTS ARE WORKING OR IN FRONT AND ALSO MY FRONT LOW LIGHT I HAVE NO VISIBILITY WHAT SO EVER.THEY ARE SO DULL.

VEHICLE WAS BEING DRIVEN ON A TWO WAY HIGHWAY AT APPROXIMATELY 55 MPH. VEHICLE LOST ENGINE POWER WHILE DRIVING AND THE GAS PEDAL LOST RESISTANCE AND WENT TO THE FLOOR. VEHICLE WAS STEERED OVER TO THE SIDE OF THE ROAD. WHILE THE VEHICLE WAS STEERED OVER TO THE SIDE OF THE ROAD, CHECK ENGINE AND OTHER DASH LIGHTS STARTED FLASHING CHAOTICALLY. WHITE SMOKE STARTED COMING FROM UNDER THE HOOD. WITHIN A SHORT TIME, WHITE SMOKE TURNED INTO BLACK SMOKE AND THEN FLAMES STARTED TO APPEARS. THE FIRE UNDER THE HOOD EVENTUALLY CONTINUED TO GROW UNTIL IT COMPLETELY BURNED THE ENGINE COMPARTMENT MOST OF THE FIRST TWO ROWS OF THE INTERIOR BEFORE THE FIREMEN ARRIVED AND WERE ABLE TO PUT OUT THE FIRE.

THE CRUISE CONTROL IS INTERMITTENT. *TR

PARKED THE VEHICLE IN A PARKING GARAGE SO I KNOW THE LIGHTS WERE WORKING WHEN WE WENT IN. AS WE WERE LEAVING APPROXIMATELY 3 HOURS LATER, THE LOW BEAMS WOULD NOT COME ON AT ALL. HAD TO RUN HIGH BEAMS; HAD SEVERAL PEOPLE LOOK AT THE FUSES, REPLACED BULBS, ETC. BUT THEY COULD NOT FIND THE PROBLEM. A COUPLE OF WEEKS LATER JUST BEFORE I WAS TAKING IT TO A DEALER TO LOOK AT THE PROBLEM THE LOW BEAMS BEGAN WORKING AGAIN. APPROXIMATELY TWO MONTHS LATER THE EXACT SAME THING HAPPENED ONLY THIS TIME I HEARD A FAINT NOISE FROM THE ENGINE COMPARTMENT AND SMELLED A BURNING (SEEMED ELECTRICAL) AROMA FOR A FEW SECONDS WHEN I REALIZED THE LOW-BEAM LIGHTS WERE NOT WORKING AGAIN. AFTER A WEEK OR SO THE LIGHTS CAME BACK ON AGAIN. *TR

MY 2004 GMC ENVOY HAS 90,000 MILES AND THE HEADLIGHTS AND TAIL LIGHTS KEEP FLICKERING WHEN I START IT. AND WHEN DRIVING DOWN THE ROAD THEY FLICKER. THE GAUGES ON THE DASH FOR THE CHARGING SYSTEM GOES UP AND DOWN. I HAVE HAD IT TO A CHEVY DEALER 4 TIMES KNOW, FIRST TIME THEY TOLD ME THE THROTTLE BODY NEEDED CLEANED. THEY DID IT. PICKED IT UP AND THEN IT WAS JUST AS BAD. TOOK IT BACK AND THEY RAN TEST AND SAID IT HAS TO DO WITH A PLUG FOR THE SECONDARY AIR INJECTION SYSTEM. THEY REPLACED IT. STILL DOING IT. THEY TOLD ME THERE IS NO FIX FOR THE PROBLEM KNOW THEY TELL ME MY SECONDARY AIR PUMP AIR IS BAD AND NEEDS REPLACED. THERE HAS TO BE A FIX FOR THIS PROBLEM. I CANT SPEND MONEY THAT DON'T FIX THE PROBLEM I AFRAID TO DRIVE IT AT NIGHT.GOING DOWN MY DRIVEWAY THE LIGHTS WENT ALL THE WAY OUT AND BACK ON. ANYTHING YOU CAN DO OR TELL ME WHAT I CAN DO WILL HELP. THANK YOU *TR

THE SPEEDOMETER AND TACHOMETER OF THE SUV BEGAN TO INDICATE INCORRECT READINGS. THE SPEEDOMETER WORKS FINE UNTIL WE GO ON THE HIGHWAY AND TRAVEL WITH THE CRUISE CONTROL SET BETWEEN 65-70. THEN THEY WILL READ THE INCORRECT SPEED FOR A WEEK OR SO THEN START WORKING FINE AGAIN. THE TACHOMETER NEEDLE JUST "HANGS." I TALKED TO 2 DIFFERENT REPAIR SHOPS WHO ADVISED ME THAT THIS IS A COMMON PROBLEM WITH ENVOY'S AND TRAILBLAZERS. THE COST TO DO THIS IS OVER $500 OR MORE. IT APPEARS THAT SEVERAL OTHER 2004 GMC ENVOY OWNERS ARE EXPERIENCING THIS SAME PROBLEM. A RECALL SHOULD BE IN ORDER. WHEN I TALKED TO THE REPAIR SHOPS THEY SAID BEFORE THEY CAN CORRECT THE ISSUE UNDER MY EXTENDED WARRANTY IS TO SEE IT HAPPEN. EACH TIME I HAD AN APPT SET IT WOULD START WORKING BEFORE THE APPT DATE SO THERE IS NOTHING THEY CAN DO. VERY IRRITATED THAT GMC DOESN'T ADDRESS THIS NOW. *TR

TL* THE CONTACT OWNS A 2004 GMC ENVOY. THE CONTACT STATED THAT THE SPEEDOMETER FAILED TO FUNCTION. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC WHERE IT WAS FOUND THAT THE INSTRUMENT CLUSTER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS NOT AVAILABLE.

THE INSTRUMENT PANEL CLUSTER ON MY GMC ENVOY 2004 IS DEFECTIVE AS IT IS ON A MULTITUDE OF OTHER GM MODELS BETWEEN 2003 AND 2005. ONE OF THE CONSEQUENCES IS THAT THE SPEEDOMETER WILL NOT WORK OR WILL REPORT A FAULTY READING WHILE OPERATING THE VEHICLE. THIS IS AN UNSAFE DRIVING CONDITION AND FOR SOME REASON GM HAS NOT YET ISSUED A RECALL ON THIS PROBLEM FOR GMC ENVOYS OF THE YEAR 2004 EVEN THOUGH OTHER YEARS OF THIS MODEL AND OTHER MODELS OF GM VEHICLES HAVE BEEN RECALLED FOR THIS EXACT ISSUE. PLEASE HELP GM DO THE RIGHT THING BY IT'S ENVOY OWNERS. WE HAVE CERTAINLY BAILED THEM OUT ENOUGH. THERE IS ANOTHER POTENTIALLY DEADLY CONSEQUENCE OF THIS ISSUE. IF ONE WERE TO BE DRIVING THE VEHICLE AT 60MPH USING CRUISE CONTROL AND THE SPEEDOMETER WERE TO ALL OF A SUDDEN PEG ITSELF TO 20MPH, THERE WOULD BE A SUDDEN AND ABRUPT ACCELERATION AS THE COMPUTER IN THE CAR ATTEMPTED TO REGAIN 60MPH EVEN THOUGH THE VEHICLE WAS ALREADY AT THAT SPEED. THANK YOU FOR YOUR TIME AND ATTENTION TO THIS DANGEROUS SPEED CONTROL ISSUE.. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

FAILURE OF THE DRIVERS DOOR MODULE. POWER WINDOWS WORK, BUT NOTHING ELSE.. NO DRIVER 1/2 OPTION BUTTONS, NOT HEATED SEATS.. *TR

I HAVE BEEN READING MANY OF THESE POST. I CAN'T BELIEVE ALL OF THE THINGS THAT HAVE ALSO HAPPENED TO MY ENVOY. I HAVE HAD MY BACK WINDOW BLOW OUT WHILE DRIVING, THANK GOD THAT BOTH OF MY KIDS THAT WERE IN THE BACK SEAT WERE NOT HURT, THEY WERE JUST SCARED AND STILL ASK IF IT WILL HAPPEN AGAIN. I ALSO RECENTLY JUST HAD TO HAVE A PIECE ON THE GAS LINE FIXED WHICH WAS ALMOST $900.00 MONEY THAT I DIDN'T HAVE AND HAD TO BORROW. I AM STILL PAYING IT BACK. NOW AS FOR LAST NIGHT MY LOW BEAMS ARE NOT WORKING, I BOUGHT NEW BULBS AND THAT DIDN'T WORK, SO IT IS BACK TO THE MECHANIC. OH AND I HAVE A CHECK ENGINE LIGHT THAT GOES ON AND OFF. THEY REALLY NEED TO GET ON ALL OF THESE THINGS. IT WOULD BE NICE TO HAVE THE CAR WORKING THE WAY IT SHOULD BE. I MAY JUST PRINT THESE THINGS UP AND BRING TO THE GMC SHOP AND SEE WHAT THE CAN DO ABOUT IT. I MEAN I REALLY TO LOVE MY SUV BUT THIS IS CRAZY. I AM NOW KIND OF SCARED TO HAVE MY KIDS IN THE CAR. *TR

WHILE DRIVING ANOTHER MOTORIST SAW SMOKE COMING FROM REAR OF VEHICLE AND GOT VEHICLE STOPPED ON SIDE OF ROAD AT WHICH TIME THE ENGINE COMPARTMENT WAS ENGULFED IN FLAMES. CALLED FIRE DEPT AND POLICE. FIRE SPREAD THROUGH THE HEARER BOX INTO THE VEHICLE AND ACROSS DASH UNTIL IT BEGAN BURNING THE HEADLINER. FIRE DEPT PUT OUT FIRE BUT WAS A TOTAL LOSS. THERE WAS NO INDICATION ON INSTRUMENT PANEL OF ANY PROBLEMS (ALL GAUGES SHOWING NORMAL READINGS). *TR

THE "CHECK GAUGES" LIGHT FLASHES FOLLOWED BY "LOW OIL PRESSURE" FOLLOWED BY "STOP ENGINE" AND THE ENGINE STALLS. EACH TIME THIS HAPPENS THE AC HAS BEEN ON. SENT TO DEALER AND THEY WERE UNABLE TO REPRODUCE THIS ISSUE. HAS HAPPENED 3 TIMES NOW. VERY SCARY. *TR

THE SPEEDOMETER BEGINS TO GIVE FAULTY READINGS. AT FIRST IT WAS REPORTING APPROXIMATELY 20 MILES PER HOUR UNDER ACTUAL SPEED. THIS ALMOST CAUSED A CRASH DUE TO EXCESSIVE UNKNOWN SPEED. IN THE LAST FEW DAYS THE SPEEDOMETER STARTS AT 60 MPH AND IS OFF BY APPROXIMATELY THE SAME AMOUNT SO WHEN TRAVELING 50 MPH THE SPEEDOMETER READS 110 MPH. THIS IS A MASSIVE SAFETY ISSUE AND THERE ARE NUMEROUS REPORTS ABOUT THIS YET NO RECALLS. HOW MANY PEOPLE MUST BE INJURED OR KILLED BEFORE YOU TAKE ACTION. *TR
