THE DASH CLUSTER DOES NOT WORK CORRECTLY, ALL THE LIGHTS TURN ON AND DOORS LOCK WHILE I AM DRIVING ON IN TOWN OR ON THE HIGHWAY , ALL THE GAUGES COME ON AT ONCE WHILE DRIVING ON THE STREETS AT RANDOM TIMES.. THE REAR HAS AIRBAGS IN THE SUSPENSION AND AND AREN'T WORKING PROPERLY, I TOOK IT TO THE SHOP AND THEY SAID IT HAD 30 CODES ON THE DIAGNOSTIC MACHINE BUT THEY COULDN'T FIND THE PROBLEM
I WAS STOPPED AT A LIGHT WHEN THE CAR ACCELERATED ON ITS OWN, I PRESSED THE BRAKE BUT THE CAR WOULD NOT STOP . I HIT CAR THE CAR IN FRONT OF ME, I HAD TO PUT CAR IN NEUTRAL TO STOP THE CAR. CAR WAS TOWED TO DEALER, THE CAUSE WAS A INTERNALLY SHORTED THROTTLE BODY. THE THROTTLE BODY WAS REPLACED. THIS WAS THE THIRD TIME CAR ACCELERATED ON OWN AND WOULD NOT STOP. THE FIRST TWO TIMES MY MECHANIC COULD NOT FIND ANY PROBLEM.
DUE TO A BRAKE PRESSURE MODULATOR VALVE PROBLEM (OPEN/SHORTED CIRCUIT), THE ABS SYSTEM ENGAGES AT ABOUT 8 MPH IN LOW SPEED STOPPING SITUATIONS ON WET AND DRY DRIVING SURFACES CAUSING TEMPORARY ENGINE STALLING AND POWER STEERING CONTROL LOSS AND LENGTHENED DISTANCE NEEDED TO STOP, INCREASING THE RISK OF CRASH.
SOME TIMES WHEN THE BRAKES ARE APPLIED THE THROTTLE ALSO ADVANCES CAUSING UNWANTED ACCELERATION. HAPPENS AT LOW SPEEDS. HAVE THERE BEEN ANY FACTORY RECALLS FOR THIS PROBLEM? *TR
SPEEDOMETER WAS NOT WORKING. TOOK 2003 GMC ENVOY TO DEALERSHIP 4 TIMES WHEN IT WAS UNDER WARRANTY AND TECHNICIAN SAID NOTHING WAS WRONG WITH SPEEDOMETER. HOWEVER, THE SPEEDOMETER STOPPED ON 50 MPH WHEN TRUCKWAS SITTING STILL, SOMETIMES HIGHER NUMBER. CALLED GMC REGARDING THE SPEEDOMETER, NO CALL BACK, AND THERE WAS NOTHING THEY COULD DO ABOUT. TRUCK IS CURRENT NOT UNDER WARRANTY. NOW HAVE TO PAY $800 OUT OF POCKET FOR REPAIRS. *AK
DT*: THE CONTACT STATED THAT THE SPEEDOMETER STOPPED WORKING ON A CONSISTENTLY. THE VEHICLE WAS TAKEN TO THE DEALER WHO DETERMINED THAT THE FAULTY SPEEDOMETER WAS CAUSED BY A MANUFACTURE DEFECT OF THE INSTRUMENT PANEL AND CLUSTER. THE SPEEDOMETER NEEDED TO BE REPLACED. THE MANUFACTURE WAS NOTIFIED. THE VEHICLE HAS NOT BEEN REPAIRED NOR REPLACED. THE CONTACT FOUND MANY COMPLAINTS (EXAMPLE: #10096707) CONCERNING THE ELECTRICAL SYSTEM.*AK
DT*: THE CONTACT STATED THE SPEEDOMETER STOPPED WORKING WITHOUT WARNING. THE DEALERSHIP DETERMINED THE SPEEDOMETER CLUSTER NEEDS TO BE REPLACED. UPON DRIVING OUT OF TOWN FOR A FEW HOURS THE SPEEDOMETER READ 120 MPH IN PARK. THE CONTACT TOOK THE VEHICLE TO THE ORIGINAL GMC DEALERSHIP AND SERVICE DEPARTMENT. THEY DETERMINED IT WAS THE CLUSTER THAT NEEDED TO BE REPLACED, AND THAT IT WOULD BE 6-8 WEEKS UNTIL THE PART WOULD BE AVAILABLE BECAUSE IT WAS ON BACK ORDER DUE TO THE HIGH VOLUME OF ENVOYS AND YUKONS THAT CLUSTERS NEEDED TO BE REPLACED. THE CONTACT FELT THAT IF A NUMBER OF GMC VEHICLES HAD FAULTY CLUSTERS THEN PERHAPS IT SHOULD BE RECALLED FOR AT LEAST FOR SUB STANDARD REASONS, IF NOT FOR SAFETY REASONS. *AK
DT: THE CONTACT STATED WHILE DRIVING, THE REDUCE POWER ENGINE AND OIL PRESSURE LOW, CHECK ENGINE IGHTS ILLUMINATED. THE VEHICLE STOPPED, ALTHOUGH, THE ENGINEWAS STILL RUNNING. THE DEALERSHIP WAS UNABLE TO DIAGNOSE A PROBLEM, BUT REPLACED THE TANK GASKET, GAS PEDAL, AND COMPUTER CHIP. THIS CAUSED THE CONTACT TO REAR END ANOTHER VEHICLE. *AK
CAR: GMC ENVOY 2003 WHEN DRIVING ON A HIGHWAY CHECK ENGINE LIGHT CAME ON. "REDUCED POWER" LIGHT CAME ON TOO. ENGINE RPMS DROPPED DOWN TO 1100. BARELY AVOIDED CRASH. *JB MADE IT TO THE PARKING LOT. RESTARTED ENGINE FEW TIMES SAME PROBLEM. EXECUTED "CLEAR CHANGE OIL LIGHT" PROCEDURE FEW TIMES. IT CLEARED "CHECK ENGINE" LIGHT AND EVERYTHING IS NORMAL NOW. THE VEHICLE IS EQUIPPED WITH "CHANGE OIL" TIMER AND LIGHT. IT APPEARS THAT WHEN TIMER EXPIRED THE COMPUTER RATHER THAN TURNING "CHANGE OIL" LIGHT ON ENABLES "CHECK ENGINE" LIGHT AND DRASTICALLY REDUCES ENGINE POWER. WHEN IT HAPPENS ON A HIGHWAY IT CAN EASILY LEAD TO A CRASH. I PLAN TO TAKE THE VEHICLE TO A DEALERSHIP IN TWO DAYS. THANK YOU.
WHILE STOPPED THE ENGINE RAN AT 900 RPM'S. AFTER THE BRAKE WAS RELEASED THE RPM'S CLIMBED TO 1100 AND THE VEHICLE ACCELERATED SUDDENLY. THE DEALER REPLACED THE FUEL EMISSIONS CANISTER ONCE, AND RESET THE ELECTRICAL CODES, AND REPLACED THE FUEL TANK, BUT THE PROBLEM RECURRED. *AK *NM
2003 GMC ENVOY HIGH ENGINE IDLE WHEN SLOWING TO STOP ENGINE WILL NOT RETURN TO IDLE UNTIL ALMOST AT A STOP. WHEN SLOWING IF YOU DO NOT TOUCH THE BRAKE PEDAL THE CAR WILL CONTINUE ON A FLAT ROAD AT 30TO 35 MPH.GM ANSWER TO THIS POINT IS THAT THEY ALL DO IT. I SEE THIS AS A SAFETY CONCERN AND ON SLIPERY ROAD CCOULD CAUSE THE VEHICLE TO SKID NOT TO MENTION UNUSUAL BRAKE WEAR AND FUEL CONSUMPTION. THAKS SAM MCNEIL. *AK
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
