2005 GMC Envoy

SPORADIC FAILURE OF SPEEDOMETER - REGISTERS CORRECTLY ONE MOMENT, OR MAY READ 30 MPH OR 0 MPG WHEN KEEPING WITH THE FLOW OF TRAFFIC ON THE INTERSTATE. WHILE THIS DOES NOT OCCUR EACH TRIP, IT DOES OCCUR SEVERAL TIMES EACH WEEK. FUEL GAUGE MALFUNCTION - READS ONE-HALF TANK AT 179 MILES; 20 MILES LATER READS ONE-QUARTER TANK. ISSUES "FUEL LEVEL LOW" WARNING AFTER REFUELING AND FOR NEXT 3 TO 4 TIMES VEHICLE IS STARTED HEADLIGHTS DIM BRIEFLY WHEN ACCELERATOR IS RELEASED. FREQUENT NEED TO REPLACE EXTERIOR LAMPS THE PROBLEMS FIRST MANIFEST IN THE NEED TO REPEATEDLY CHANGE BRAKE AND TAILLIGHT BULBS, AND THE DIMMING OF THE HEADLIGHTS, WHICH CONTINUES. THEN, SPORADICALLY, THE SPEEDOMETER STOPPED FUNCTIONING, OR ONLY REGISTERED A FRACTION OF THE SPEED THE VEHICLE WAS TRAVELING. AFTER THAT, AT START UP, THE "FUEL LEVEL LOW" WARNING, WHICH ACTIVATES WHEN THE VEHICLE DETERMINES IT HAS FUEL TO TRAVEL 40 ADDITIONAL MILES, STARTED TO CHIME WHEN THERE WAS MORE THAN ONE-HALF TANK OF FUEL. THE WARNING ALSO NOW ISSUES WHENEVER THE VEHICLE IS REFUELED. THE POTENTIAL FAILURE OF THE EXTERIOR LIGHTING SYSTEM PRESENTS A CLEAR HAZARD TO THE OCCUPANTS OF THE VEHICLE AND OTHERS - THE DRIVER WOULDN'T BE ABLE TO SEE WHERE HE IS GOING, AND OTHER DRIVERS WOULDN'T BE ABLE TO SEE THE VEHICLE HEADING TOWARD THEM. THE FUEL SYSTEM ISSUES COULD LEAD TO UNEXPECTEDLY RUNNING OUT OF FUEL, CREATING THE POTENTIAL FOR A DISABLED VEHICLE OR ITS DRIVER BEING HIT BY ANOTHER. IN ADDITION, DEPENDING ON THE CAUSE OF THE MALFUNCTION, THE VEHICLE COULD BE SUSCEPTIBLE TO FIRE. WITHOUT A FUNCTIONING SPEEDOMETER, THE DRIVER CAN EASILY TRAVEL TOO FAST FOR CONDITIONS, OR ENDANGER HIMSELF AND OTHERS IN A CONSTRUCTION ZONE. CURRENTLY, UNTIL THE SPORADIC PROBLEMS BECOME REGULAR, THE GARAGE WILL NOT FIX THE VEHICLE. *TR

OUT OF NOWHERE MY FRONT HEAD LIGHTS WENT OUT. ITS NOT THE FUSE OR THE BULBS, BOTH FRONT LOW LIGHTS WENT OUT. THE HIGH BEAMS WORK. THERE IS NO POWER GOING TO THE LIGHTS AND I HAVE TO BUY A NEW SWITCH. I ALSO HAD TO REPLACE THE ENGINE ALMOST A YEAR AGO BECAUSE THE O RINGS WENT UP. THE GAS GAUGE IS BROKEN AND MY PASSENGER WINDOW WILL NOT GO DOWN. I FEEL SO STUCK WITH THIS CAR! *TR

CAR SWITCHES INTO ALL 4W AND HIGHER BY ITSELF. I HAD BEEN TO A DEALERSHIP 3 TIMES IN ONE YEAR FOR WHICH THEY WERE UNABLE TO FIND THE PROBLEM. NOW MY WARRANTY IS UP. AFTER THAT I TOOK IT TO A TRANSMISSION SHOP WHERE THEY SUPPOSEDLY FIXED THE PROBLEM FOR OVER 800.$ A WEEK LATER IT DID IT AGAIN. NOW I HAVE THE 4WD DISCONNECTED FOR SAFETY REASONS. I WOULD BE DRIVING ON THE FREEWAY AT 60-75 MPH AND IF WOULD SWITCH AND NOT COME OUT NO MATTER WHAT I DO. I HAVE OWNED THIS VEHICLE FOR ALMOST 5 YEARS AND IT HAS DONE THIS THE WHOLE TIME. I AM A SINGLE MOM AND I DRIVE MY 17 AND 7 YEAR OLD AROUND IN THIS CAR. EVEN WITH IT DISCONNECTED IT STILL TRIES TO SWITCH. THERE IS NO SPECIFIC TIME, TEMPERATURE, OR OTHER REASON THIS HAPPENS. IT HAS HAPPENED WHEN I TURN ON THE CAR AND SOMETIMES I CAN GO A COUPLE OF WEEKS AND OTHER TIMES IT HAPPENS DAILY. I ALSO HAVE HAD MY LIGHTS NOT GO ON FOR NO REASON AND ALSO THE DOORS LOCK AND CAN ONLY BE UNLOCKED BY USING THE KEY. AND THE HATCHBACK WILL NOT OPEN AT ALL WHEN THIS HAPPENS. ELECTRICAL?? HELP!! *TR

TL*THE CONTACT OWNS A 2005 GMC ENVOY. WHILE DRIVING AT AN UNKNOWN SPEED, THE INTERIOR AND EXTERIOR HEAD LAMPS FAILED SIMULTANEOUSLY WITHOUT WARNING. AS A CONSEQUENCE, VISIBILITY IS SIGNIFICANTLY REDUCED, WHICH INCREASES THE RISK OF A CRASH. THE VEHICLE WAS TAKEN TO THE DEALER NUMEROUS TIMES, BUT THEY CANNOT DETERMINE THE CAUSE OF THE FAILURE. HE IS IN THE PROCESS OF NOTIFYING THE MANUFACTURER. THE FAILURE MILEAGE WAS 26,000 AND CURRENT MILEAGE WAS 46,000.

TL*THE CONTACT OWNS A 2005 GMC ENVOY. THE CONTACT STATED THAT HE WAS EXPERIENCING ISSUES WITH THE HEADLIGHTS. WHEN HIS WIFE WOULD DRIVE THE VEHICLE AT 50 MPH, THE HEADLIGHTS WOULD GET DIMMER AND DIMMER AND THEN BRIGHTEN AGAIN. ON ONE OCCASION, THE LIGHTS TURNED OFF COMPLETELY AND HIS WIFE HAD TO DRIVE HOME WITH THE HAZARD LIGHTS FLASHING. THE ISSUE OCCURRED INTERMITTENTLY. THE CONTACT TOOK THE VEHICLE TO THE DEALER AT LEAST FOUR TIMES AND THEY CHANGED THE SWITCHES AND RECALIBRATED THE LIGHTS. THE REPAIRS CAUSED OTHER FAILURES; THEREFORE, THEY RECALIBRATED TO THE ORIGINAL LIGHTS. THE DEALER STATED THAT THERE WAS NO REMEDY FOR THE FAILURE. THE MANUFACTURER STATED THAT THEY WOULD START A CASE FOR HIM AND CALL HIM BACK. THE CURRENT MILEAGE WAS APPROXIMATELY 41,000 AND FAILURE MILEAGE WAS APPROXIMATELY 23,000. UPDATED 11/14/08 *CN THE CHECK ENGINE LIGHT ILLUMINATED. THE DEALER REPLACED THE O2 SENSOR. UPDATED 11/18/08. *JB

I PURCHASED A 2005 GMC ENVOY IN SEPTEMBER 2005. IN THE PAST YEAR (SINCE JANUARY 2007, AT LEAST), I HAVE EXPERIENCED SEVERAL PROBLEMS WITH MY VEHICLE. THE FIRST PROBLEM IS WITH THE HEADLIGHTS. EVERYTIME I HAVE DRIVEN THE VEHICLE THE HEADLIGHTS APPEAR TO DIM/FLICKER AND THEN RETURN TO NORMAL. THIS HAS RESULTED IN ONCOMING VEHICLES TURNING THEIR BRIGHT LIGHTS ON ME THINKING MY BRIGHTS ARE ON WHEN IN REALITY MY HEADLIGHTS ARE DIMMING AND THEN RETURNING TO NORMAL. THE SECOND PROBLEM CONCERNS THE PASSENGER SIDE AIRBAG. ANYTIME A CERTAIN WEIGHT LIMIT IS MET OR EXCEEDED THE AIRBAG SENSOR IS SUPPOSED TO SWITCH TO ON, BUT THERE HAVE BEEN SEVERAL OCCASIONS WHEN SOMEONE WAS SITTING IN THE PASSENGER SEAT AND THE AIRBAG SENSOR HASN'T RECOGNIZED IT. THIRD PROBLEM, DRIVER SIDE POWER SEAT FAILURE. THERE HAVE BEEN SEVERAL INSTANCES WHEN I HAVE TRIED TO MOVE THE DRIVER SEAT FORWARD, BUT NOTHING HAPPENED. THE MOTOR SOUNDED LIKE IT WAS GRINDING AND WANTED TO MOVE, BUT THE SEAT WOULD NOT MOVE FORWARD OR BACKWARD. THE MOST EXTREME PROBLEM TO DATE HAS BEEN WITH THE VEHICLE COMPLETELY SHUTTING OFF WITHOUT WARNING WHILE IN THE MIDDLE OF DRIVING AND THEN NOT STARTING OR EVEN TURNING OVER AT ALL. EVERY SINGLE DAY FOR, AT LEAST, THE LAST MONTH WHEN I GO TO START THE VEHICLE IT FAILS TO START AND IT TAKES A MINIMUM OF 1 HOUR TO GET IT STARTED. ONE INSTANCE IN PARTICULAR WHEN THE VEHICLE SHUT OFF WITHOUT WARNING WAS WHILE MY WIFE AND I WERE ON THE FREEWAY. WITHOUT WARNING THE VEHICLE SHUT DOWN AND WE WERE FORCED TO PULL ONTO THE SHOULDER. WE SAT THERE FOR ALMOST AN HOUR IN TEMPERATURES OF 13 DEGREES TRYING TO GET THE VEHICLE RESTARTED. THERE HAVE BEEN COUNTLESS COMPLAINTS AND REPORTS OF OTHER ENVOY OWNERS EXPERIENCING THESE SAME PROBLEMS. SOME DEALERS HAVE ACTUALLY SAID THAT THESE FAILURES/PROBLEMS ARE NORMAL!!!! WHAT!?!?! ARE YOU FREAKING KIDDING ME?! SINCE WHEN IS IT CONSIDERED "NORMAL" WHEN SO MANY ENVOYS ARE DISPLAYING THESE SAME PROBLEMS? *TR

TL* THE CONTACT OWNS A 2005 GMC ENVOY. WHILE DRIVING THE VEHICLE APPROXIMATELY 30 MPH THE HIGH BEAMS BEGAN TO BLINK WHEN THE CONTACT REMOVED THE FOOT FROM THE ACCELERATOR PEDAL. THE CONTACT WAS DRIVING BEHIND A POLICE OFFICER, AND WHEN ATTEMPTING TO DECELERATE, THE HIGH BEAMS STARTED BLINKING. THE OFFICER STOPPED HIM AND STATED THAT IT WAS A SAFETY PROBLEM. THE CONTACT TOOK THE VEHICLE TO DEALER FOR REPAIR, BUT WAS UNABLE TO PERFORM REPAIRS. AFTER THE VEHICLE LEFT THE SHOP THE FAILURE OCCURRED AT 50 MPH. THE MECHANIC PERFORMED A DIAGNOSTIC, AND FOUND NO FAILURES. THE GMC TECHNICAL SUPPORT REPRESENTATIVE STATED THAT THEY WERE AWARE OF THE FAILURE, BUT DID NOT KNOW HOW TO PERFORM THE REPAIRS. THE CURRENT MILEAGE IS 37,000 AND FAILURE MILEAGE WAS 1,000. *AK
