2004 GMC ENVOY Complaints

I WAS TRAVELING NORTHBOUND ON RT 251 FROM PERU TO MENDOTA IL WHEN IT BEGAN RAINING AND HAILING VERY HARD. 251 IS FULL OF POT HOLES. I WAS TRAVELING ABOUT 40 M.P.H. I HIT A POT HOLE AND MY CAR STARTED TO HYDROPLAN. I WENT INTO THE SOUTHBOUND LANE AND THEN INTO DITCH HEAD ON....I HIT THE DITCHES WALL ALMOST HEAD ON AND MY AIRBAGS DID NOT COME OUT. *TR

ERRATIC SPEEDOMETER OPERATION. SHOWS VARIOUS SPEEDS WHEN STOPPED. INACCURATE WHEN UNDERWAY. WILL SHOW UP TO 110 MPH DRIVING IN THE CITY. DEALER SAYS INSTRUMENT PANEL NEEDS TO BE REPAIRED AT COST OF OVER $400. SAME PROBLEMS ON FULL SIZE GM TRUCKS. FULL SIZE TRUCKS ARE BEING COVERED UNDER SERVICE BULLETIN #07187A, B, & NOW C. SPEEDOMETER REPAIR SHOP SAYS STEPPER MOTORS ARE BAD. SAME PART NUMBER AND REPAIR AS ON FULL SIZE TRUCKS. GM HAS EXCLUDED ENVOY AND TRAILBLAZER FROM THIS REPAIR COVERAGE. *TR

REAR AIR BAGS LEAK DOWN AND THEN AT RANDOM PUMP BACK UP. TOOK IT MOORE BUICK FOR REPAIR AND, ONCE AGAIN, THEY REPLACED AN EXPENSIVE PART AND THIS A.M. THE AIR BAGS HAD LEAKED DOWN AGAIN. THIS IS THE LAST VEHICLE I WILL BUY FROM MOORE BUICK AND/OR GMC. *TR

SPEEDOMETER DOES NOT WORK AT TIMES. SOMETIMES IT WILL JUST STAY AT "0", OTHERS IT WILL BE AT VARIOUS SPEEDS EVEN WHILE IN PARK. *TR

04/12/2009 THE SPEEDOMETER JUMPED TO 110 MPH WHILE ONLY DRIVING ABOUT 25 MPH. TURN THE CAR OFF AND IT STAYED AT 110. TURN ON AGAIN AND WHILE DRIVE ABOUT FORTY MPH IT SHOWS 150 ISH. CALL THE DEALER AND REPLACEMENT IS OVER $400 TO REPLACE THE PART (ASSUMING THAT THIS IS THE FIX). EXTENSIVE RESEARCH AND THE AMOUNT OF COMPLAINTS ON THIS SITE, THIS IS A RATHER LARGE PROBLEM THAT HAS EFFECTED A LARGE QUANTITY OF GM OWNERS. THIS SEEMS TO BE A DEFECTIVE PART THAT HAPPENS GENERALLY RIGHT AFTER THE WARRANTY RUNS OUT. GO FIGURE. *TR

SPEEDOMETER DEFECT - KNOWN ISSUE BUT NO RECALL; CAN'T TELL HOW FAST OR SLOW I'M GOING, AFTER READING FORUMS, NOT SURE IF OTHER DASHBOARD PROBLEMS - HARD TO DRIVE SAFELY WHEN TRYING NOT TO WATCH THE DASH TO SEE IF SOMETHING OTHER THAN SPEEDOMETER INDICATES A PROBLEM. DISTRACTION TO THE POINT OF BEING DANGEROUS - ESPECIALLY AROUND THIS AREA. WHAT ABOUT SCHOOL ZONES? *TR

I HAVE A 2004 GMC ENVOY THAT THE INSTRUMENT CLUSTER WENT BAD ON AND THE DEALER WANT $900.00 TO REPAIR. ON THE INTERNET THAT THERE ARE ALOT OF GMC SUV'S WITH THE SAME PROBLEM. I, AS WELL, HAVE BEEN FIGHTING WITH GM FOR REPLACEMENT OF THE INSTRUMENT PANEL ON MY 2004 ENVOY. THE CAR HAD 48K MILES ON IT WHEN THE PROBLEM STARTED, BUT IT HAD 56K WHEN IT WAS TAKEN TO THE DEALERSHIP. IT WAS REQUIRED THAT I HAVE THE PROBLEM OFFICIALLY DIAGNOSED, WHICH COST ME $85. I WAS ASSURED THAT I WOULD GET THAT AMOUNT CREDITED TOWARD THE FIX. SCHEDULED TO GET YET ANOTHER UPDATE CALL FROM GM TOMORROW. SHORTLY AFTER I PAID OUT THE $85 AND SENT THEM MY INFORMATION, I RECEIVED BOTH AN EMAIL AND A PHONE CALL SAYING "SORRY, WE CAN'T OFFER ANY ASSISTANCE". I CALLED THEM RIGHT BACK TO ESCALATE IT FURTHER. I'M PUSHING IT AS FAR AS I CAN. THE REPRESENTATIVE TOLD ME THAT THERE HAVEN'T BEEN ENOUGH COMPLAINTS WITH THE ENVOYS YET, ALTHOUGH SHE ADMITTED THAT THERE HAVE BEEN A LOT, AND BECAUSE OF THIS OBVIOUS PROBLEM, THE CASES WOULD BE HANDLED ON AN INDIVIDUAL BASIS AT THIS POINT. WHAT MORE PROOF DO WE NEED? *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

TL*THE CONTACT OWNS A 2004 GMC ENVOY. WHILE DRIVING APPROXIMATELY 45 MPH ON NORMAL ROAD CONDITIONS, THE CONTACT REAR-ENDED THE PRECEDING VEHICLE. THERE WERE NO DAMAGES TO THE VEHICLES OR THE OCCUPANTS. HE PULLED OVER TO THE SIDE OF THE ROAD AND NOTICED SMOKE SUDDENLY APPEARING FROM THE FRONT END OF THE VEHICLE. IMMEDIATELY, THE PASSENGER COMPARTMENT BECAME ENGULFED IN FLAMES. THE CONTACT SAFELY EXITED THE VEHICLE. THE POLICE AND FIRE DEPARTMENTS WERE CALLED TO THE SCENE AND A REPORT WAS FILED. THE VEHICLE WAS COMPLETELY DESTROYED AND TOWED TO A COLLISION CENTER. THE INSURANCE COMPANY WAS NOTIFIED; HOWEVER, THE CAUSE OF THE FAILURE HAS NOT YET BEEN DETERMINED. THE VIN WAS UNKNOWN. THE FAILURE AND CURRENT MILEAGES WERE 75,000.

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 ACCIDENT. I AM REQUESTING THAT THE NHTSA FORMALLY INVESTIGATE THIS PROBLEM BEFORE THIS HAPPENS. *TR
