2004 GMC Envoy

UPON ATTEMPTING TO START THE VEHICLE, ALL THE DASH BOARD WARNING LIGHTS AND TURN SIGNAL INDICATORS CAME ON AND STAYED ON. ALL THE GAUGES STARTED ACTING ERRATICALLY AND ALL THE NEEDLE INDICATORS STARTED JUMPING AT RANDOM. WHEN I TURNED OFF THE VEHICLE AND TRIED TO START THE VEHICLE AGAIN, THE VEHICLE STARTED WITHOUT ANY PROBLEMS. THE VERY NEXT TIME I TRIED TO START THE VEHICLE; IT DID THE VERY SAME THING AS MENTIONED ABOVE (GAUGES ACTING ERRATICALLY, ETC.). I ATTEMPTED TO START THE VEHICLE SEVERAL MORE TIME EACH TIME WITH THE SAME RESULT. FINALLY THE VEHICLE STARTED AND NO FURTHER PROBLEMS WERE EXPERIENCED. I DROVE THE VEHICLE FOR APPROXIMATELY 1200 MILE OVER THE NEXT FEW DAYS. YESTERDAY, I WAS DRIVING HOME AT A SPEED OF APPROXIMATELY 35 MPH WHEN THE VEHICLE SUDDENLY AND WITHOUT WARNING QUIT. I COASTED TO A SAFE SPOT ON THE SHOULDER OF THE ROAD. I TRIED MULTIPLE TIMES TO RESTART THE VEHICLE. EACH TIME THE VEHICLE EXHIBITED THE SAME SYMPTOMS AS MENTIONED ABOVE E.G. GAUGES ACTING ERRATICALLY. AFTER ABOUT 5 MIN. THE VEHICLE STARTED NORMALLY AND I WAS ABLE TO DRIVE HOME. IN MY DRIVEWAY I ATTEMPTED TO START THE VEHICLE SEVERAL TIME. EACH TIME THE VEHICLE EXHIBITED THE SAME SYMPTOMS AS MENTIONED ABOVE E.G. GAUGES ACTING ERRATICALLY. UPON CONSULTING WITH A LOCAL MECHANIC AND A LOCAL DEALER, I WAS INFORMED THE PROBLEM WAS MOST LIKELY A BAD IGNITION SWITCH. THE VEHICLE IS CURRENTLY HAVING THE SWITCH REPLACED. *JB

I PURCHASED A 2004 GMC ENVOY WITH APPROXIMATELY 50000 MILES ON IT IN MAY OF 2006. ABOUT 4 MONTHS LATER, THE SPEEDOMETER STARTED ACTING SLIGHTLY ERRATIC, REPORTING SPEEDS VARYING BY 10-20 MPH (I.E. ON THE HIGHWAY, KEEPING UP WITH TRAFFIC AT 65 MPH, THE SPEEDOMETER WOULD REPORT 45 MPH OR SOMETIMES 80 MPH. OVER THE PAST FEW WEEKS, THE PROBLEM HAS GOTTEN MUCH WORSE, WITH THE SPEEDOMETER REPORTING 120 MPH AT HIGHWAYS SPEEDS, AND 50 MPH AT A STOP, SOMETIMES NOT REGISTERING ANY SPEED AT ALL (O MPH). THE CRUISE CONTROL HAS ALSO STOPPED WORKING, WHICH I AM ASSUMING IS RELATED TO THE SPEEDOMETER MALFUNCTION. I SEARCHED ONLINE, AND APPARENTLY THERE ARE MANY OTHER GMC OWNERS WITH THE SAME EXACT PROBLEM. PLEASE SEE LINK BELOW: HTTP://WWW.TOPIX.NET/FORUM/AUTOS/CHEVROLET-TAHOE/T2BGKBGI55EKNU77C/P1 THIS IS THE FIRST GMC CAR I HAVE PURCHASED AND I AM DISSATISFIED WITH THIS SAFETY ISSUE. I AM A PRETTY GOOD GUESS AT HOW FAST I AM GOING, HOWEVER WITHOUT AN ACCURATE SPEEDOMETER I FEEL I AM TAKING UNNECESSARY CHANCES. AS A REALTOR, I OFTEN HAVE CLIENTS IN MY VEHICLE AND I AM CONCERNED FOR THEIR SAFETY AS WELL. I FILED A COMPLAINT WITH GMC, BUT I WAS REFERRED TO THE DEALER AS THERE ARE NO CURRENT RECALLS FOR THIS PROBLEM. THE DEALER SAYS THAT THIS IS A $500 FIX, AND I AM CONCERNED AS THIS APPEARS TO BE A MANUFACTURER DEFECT, BASED ON THE NUMBER OF OTHER CONSUMERS WITH THIS SAME ISSUE. I NEVER EXPECTED TO HAVE AN ISSUE THIS PROBLEMATIC WITH A VEHICLE 2 YEARS OLD. I HOPE THAT BY REPORTING THIS ISSUE, THE NHTSA WILL BE ABLE TO HELP ME AND THE OTHER HUNDREDS OR THOUSANDS OF CONSUMERS WITH THIS SAFETY ISSUE. THANK YOU FOR YOUR TIME.

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

THE BLOWER MOTOR ON OUR 2004 GMC ENVOY QUIT WORKING AND UPON TAKING IT TO THE DEALER TO REPAIR, THE DEALER INDICATED THAT THE BLOWER MOTOR RESISTOR AND THE WIRING HARNESS THAT PLUGS INTO THE RESISTOR HAD MELTED TOGETHER. WHEN ATTEMPTING TO ORDER THE TWO PARTS (RESISTOR AND WIRING HARNESS), IT WAS DETERMINED THAT THE WIRING HARNESS IS ON NATIONWIDE BACKORDER. THE SERVICE MANAGER ALSO INDICATED THAT HE HAS 5 OTHERS ON BACKORDER. FROM THAT COMMENT, HE INDICATED THAT THERE IS A MAJOR ISSUE WITH THE WIRING HARNESS AND RESISTOR MELTING TOGETHER ON A NATIONAL BASIS. THE FACT THAT THE HEAT WAS SO GREAT TO MELT THESE TWO COMPONENTS TOGETHER CLEARLY INDICATES A POSSIBLE FIRE AND SAFETY HAZARD. I BELIEVE IT'S SOMETHING THAT SHOULD BE INVESTIGATED AND A RECALL ISSUED. *JB

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.

HEADLIGHTS, INTERIOR LIGHTS, ALL LIGHTS ON VEHICLE FLICKER WHILE DRIVING ON THE HIGHWAY. THE VEHICLE DOES THIS WHEN THERE IS NO APPARENT LOAD ON THE ELECTRICAL SYSTEM (I.E. BLOWER, DEFROSTER, AC, POWER SEATS, WINDOWS ETC.) THE LIGHTS BECOME VERY DIM AND THEN BRIGHT AGAIN IN THE MATTER OF A FEW SECONDS. THIS CAN BE DANGEROUS TO VEHICLES IN FRONT OF YOU AND APPROACHING AS THEY BELIEVE THEY ARE GETTING "FLASHED" BY YOUR VEHICLE. IT IS VERY UNNERVING DRIVING WITH THIS RANDOM OCCURRENCE. *NM

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 CAN LOOK AT IT AND BECAUSE I AM IN SALES, I AM ALSO FORCED TO GET A RENTAL CAR. AFTER ALL THIS, I AM STILL QUITE DISPLEASED WITH GMC. I HATE TO SAY IT BUT THEY ARE SUPPOSED TO BE THE BEST AMERICAN CAR ??PROFESSIONAL GRADE?? AND IF THIS IS TRUE I WILL NEVER BUY AN AMERICAN VEHICLE AGAIN. GMC SAID THEY WOULD BE CHECKING ON ALL THESE PROBLEMS AND EVERY SINGLE TIME I PICKED MY ENVOY UP AFTER THEY SUPPOSEDLY FIXED THE PROBLEMS, I FOUND SEVERAL ISSUES STILL UNRESOLVED. THEY SUGGEST I NEED TO SET ANOTHER MEETING TO BRING MY ENVOY IN AND OF COURSE WILL COST ANOTHER $100. *NM

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 REMOVE MY CHILDREN FROM THE CAR. *NM
