TL* THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT SATED THAT THE VEHICLE FAILED TO SHIFT OUT OF DRIVE INTO THE PARK POSITION. THE PARKING BRAKE WAS ENGAGED TO SECURE THE VEHICLE FROM MOVING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO REPLACED THE SHIFTER LINKAGE BUSHING. THE MANUFACTURER WAS CONTACTED AND INFORMED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 196,000.
WHILE DRIVING THE ENVOY AT ABOUT 45 MPH, A WARNING LIGHT SAYING "REDUCED ENGINE POWER" CAME ON SUDDENLY, THE CAR DROPPED DOWN TO ABOUT 20 MPH, AND THAT CONTINUES TO OCCUR. I CAN TURN OFF AND RESTART THE CAR, BUT THE PROBLEM RETURNS WITHIN A MINUTE AFTER DRIVING IT AGAIN. I STARTED INVESTIGATING WHAT THAT MEANS ONLINE, AND, AS WITH ANYTHING ELSE ON THE INTERNET, I SEE MANY OPINIONS, GUESSES, AND POSSIBILITIES. COULD BE A BAD SENSOR, BAD THROTTLE CONTROL, BAD WIRE CONNECTIONS, ETC. BUT THIS MUCH APPEARS CLEAR: (1) IT IS A GM PROBLEM, AND A VERY, VERY COMMON ONE. (2) IT IS A DANGEROUS PROBLEM. THIS SEEMS PRETTY OBVIOUS - THE CAR SUDDENLY LOSES SPEED AND EVIDENTLY SOMETIMES STALLS OUT ALTOGETHER. BUT HEARING ABOUT SO MANY OTHER PEOPLE'S SCARY EXPERIENCES JUST CONFIRMS THIS. (3) IT CAN BE DIFFICULT AND EXPENSIVE TO DIAGNOSE AND FIX. WHEN I THINK OF THESE FACTS, COUPLED WITH GM'S RECENT HISTORY, I IMMEDIATELY THINK "RECALL." THIS CERTAINLY APPEARS TO BE AN APPROPRIATE SITUATION FOR A MANUFACTURER TO STEP IN AND FIX THE ISSUE BEFORE MORE PEOPLE GET ANGRY WITH GM, GET HURT, OR GET KILLED. I CALLED THE DEALER WHO SOLD THE CAR (I AM THE SECOND OWNER), IN COLUMBUS, OHIO. I WAS TOLD THAT I CAN BRING IT IN FOR A DIAGNOSIS FOR $110. (GEE, THANKS - WOULDN'T HAVE THOUGHT OF THAT.) THE CUSTOMER REP LOOKED UP THE VIN AND SAID THAT THE VEHICLE WAS NOT ELIGIBLE FOR RECALL OR ANY SPECIAL POLICY. THEREFORE, I AM CONTACTING YOU IN HOPE THAT SOMETHING ELSE CAN BE DONE.
WHEN NEW, THE VEHICLE WOULD UNEXPECTEDLY GO INTO 4-WHEEL DRIVE IN A SLIGHT LEFT TURN MAKING THE VEHICLE VERY HARD TO STEER. I TOOK IT BACK TO THE DEALER OF PURCHASE AND HE REPORTED THEY COULD NOT FIND THE PROBLEM. AFTER MY WARRANTY RAN OUT HE REPORTED THE FOLLOWING; 611 ENCODER ACTUATOR, 7764 CST, 1 89059275 ACTUATOR. HE REPLACED THE ACTUATOR AT A COST OF $275.30 FOR THE ACTUATOR AND $221.90 LABOR FOR A TOTAL OF 497.20 AT MY COST! HERE IT IS SEVERAL YEARS LATER AND THE VEHICLE IS STILL DOING THIS OCCASIONALLY DANGEROUS MANEUVER. I CAN'T LET MY WIFE DRIVE MY VEHICLE BECAUSE OF THE SAFETY FACTOR OF THIS HAPPENING IN HEAVY TRAFFIC. I GUESS I HAVE NO CHOICE BUT LIVE WITH THIS? *TR
TL* THE CONTACT OWNS A 2002 GMC ENVOY .THE CONTACT STATED THAT HE ATTEMPTED TO SHIFT INTO DRIVE BUT THE GEAR SHIFTER WOULD NOT MOVE. THE VEHICLE WAS TOWED TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THE SHIFTER SOLENOID NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 134,500.
STOP ENGINE/LOW OIL PRESSURE DISPLAY CONTINUALLY COMES ON AND WHILE DRIVING, THE VEHICLE HESITATES AND AT TIMES WILL STALL. AFTER REPLACING PCM, OIL SENDING UNIT, THROTTLE BODY ASSEMBLY, CLEANING THE PCV VALVE AND MAP SENSOR AND MULTIPLE OTHER PARTS, I WAS TOLD THAT THE DEALERSHIP DID NOT KNOW WHAT IT WAS AND STATED THAT THEY COULD REPLACE THE CAM SHAFT ACTUATOR (FOR A COST OF APPROX. $885), BUT THEY COULD NOT GUARANTEE THAT WOULD RESOLVE THE PROBLEM. I HAVE TAKEN MY VEHICLE BACK TO THE SAME DEALERSHIP FROM 02/14/2011 UNTIL 11/07/12 AND STILL UNABLE TO FIX THE PROBLEM. I'VE FILED A COMPLAINT WITH GMC MANUFACTURER, BUT STILL HAVE NOT BEEN ABLE TO RESOLVE MY ISSUES. *TR
TL* THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT WAS DRIVING 25 MPH WHEN THE GEARS ON THE DIFFERENTIAL STARTED GRINDING AND DETACHED FROM THE VEHICLE. THE VEHICLE WAS TOWED TO A LOCAL MECHANIC WHERE THE MECHANIC CONFIRMED THE FRONT DIFFERENTIAL FAILURE. THE MANUFACTURER WAS NOT CONTACTED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGES WERE 131,000.
WHEN I START THE TRUCK IN THE MORNING IT SOUNDS LIKE THE ENGINE IS REVVED UP WITH THE LOUD FAN NOISE. I HAD THE FAN CLUTCH REPLACED INDEPENDENTLY AND THE LOUD NOISE CONTINUES AND A SLIGHT LOSS OF POWER AT TIMES WHILE DRIVING AND IT FEELS LIKE IT'S TAKING TOO LONG SHIFT INTO THE NEXT GEAR. THE NOISE IS REALLY HEARD WHEN YOU ACCELERATE ON THE GAS PEDAL. *TR
ROARING SOUND, NO POWER, VEHICLE CAN BARELY REACH 30MPH, LOUD NOISE HAS EXISTED FOR LONG TIME (SEVERAL YEARS) AND THE POWER PROBLEM USUALLY RESOLVED AFTER ABOUT 5 MINUTES. THIS IS A DEFECT. I FOUND HUNDREDS OF OWNERS COMPLAINING OF SAME PROBLEM ON LINE. DEALER REPLACED FAN CLUTCH. *TR
I WAS DRIVING ALONG INTERSTATE 75 AT NIGHT WITH MY 3 YEAR OLD, 16 YEAR OLD, AND 18 YEAR OLD NEPHEW RETURNING TO COLLEGE AFTER WINTER BREAK ON JAN. 2,003. WE WERE LEFT STRANDED ON THE SIDE OF THE HIGHWAY, AFTER WE ALMOST WRECKED. THE GEARS WERE JUMPING BACK AND FORTH FROM 2 WHEEL TO WHEEL DRIVE. I TOOK TO A LOCAL GM DEALER AND THEY TOLD ME THAT IT WOULD COSTS ME 2500 TO REPAIR-THE PROBLEM THE FRONT DIFFERENTIAL. I CONTACTED THE 1800 GM SERVICE LINE AND THEY SAID THAT THEY WOULD NOT BE ASSISTING WITH REPAIRS DUE TO MILEAGE. I ASKED AROUND AT DIFFERENT AUTO REPAIR AND TRANSMISSION SHOPS AND THEY SAID THAT GM KNOWS THEY HAVE A PROBLEM WITH THE DIFFERENTIAL IN ENVOYS, TRAILBLAZERS, AND ISUZUS. EVEN IF THE PROBLEM GETS FIXED, IM TOLD THERE IS NO GUARANTEE THAT THE PROBLEM WILL NOT HAPPEN AGAIN UNTIL GM ADDRESSES THE ACTUAL PROBLEM WITH THE DIFFERENTIALS. I BELIEVE MY GEAR PROBLEM CAUSED THE DIFFERENTIAL TO FAIL. MEANWHILE I AM STUCK WITH A CAR THAT I HAVE TO PAY FOR ANOTHER YEAR AND A HALF ON. IT IS REALLY AN INCONVENIENCE TO ME. I CANNOT AFFORD THE REPAIR, THE CAR SITS IN THE DRIVEWAY. IM BEHIND ON MY CAR PAYMENT, HAVING TO RENT A CAR TO DRIVE TO WORK. GM SHOULD BE HELD ACCOUNTABLE. OTHER PROBLEMS INCLUDE THE CLUTCH FAN GOING OUT, COSTING ME OVER $500 TO REPAIR ON MY OWN. GM REFUSED TO HELP. THIS WENT OUT AT 33,000, SHORTLY AFTER PURCHASE. I AM REALLY BURDENED RIGHT NOW AND DON'T KNOW WHAT TO DO. *TR
COLLAPSE OF THE RIGHT FRONT LOWER AXE. AND THE DISLOCATION OF THE RIGHT WHEEL.*AK
WE PURCHASED A $33,000 NEW VEHICLE IN OCTOBER. WE IMMEDIATELY NOTICED THE PASSENGER FRONT SEAT SEATBELT LOCKS THEN STARTS TO TIGHTENING AND NEVER UNLOCKS. I BROUGHT THE ISSUE TO THE SERVICE DEPARTMENT, THE NEW CAR SALES MANAGER, AND GMCS ATTENTION. DEAN CLOUD IN BENTLEYS SERVICE DEPARTMENT TOLD ME THAT THE SEATBELT IS DESIGNED TO LOCK SO A CHILDS SAFETY SEAT CAN BE PUT IN THE FRONT SEAT. I SHOWED HIM THAT THE VISORS IN THE CAR AND THE USERS MANUAL SAY NEVER PUT A CAR SEAT IN THE FRONT WITH THE AIR BAGS. HE SAID THAT THE PASSENGER MUST UNHOOK THE SEAT BELT EVERY FEW MINUTES THEN RECONNECT IT. I FIND THIS UNACCEPTABLE. THE DEALERSHIP IS PUTTING THE PASSENGERS IN THE VEHICLE IN AN UNSAFE AND ILLEGAL SITUATION BY TELLING THEM THE ONLY SOLUTION IS TO DISCONNECT THE SEATBELT WHILE THE VEHICLE IS IN MOTION. THE SEATBELT IN ITS CURRENT CONDITION IS CHOKING THE PASSENGERS, WHICH IS ALSO UNSAFE. THE SEATBELT NEEDS TO BE REPAIRED OR REPLACED. THE DIFFERENTIAL UNIT HAD TO BE REPLACED. THE BEARINGS DID NOT HAVE ENOUGH TOURQE (THAT IS WHT THE DEALER TOLD ME).*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.
