2002 GMC ENVOY Power Trainautomatic Transmission Problems

I JUST EXPERIENCED A SAFETY DEFECT THAT COULD HAVE HAD VERY SERIOUS CONSEQUENCES. IT INVOLVES THE FAILURE OF THE SHIFT CABLE ATTACHMENT TO THE TRANSMISSION MOUNTED SHIFT LEVER. YOU UNKNOWINGLY LOOSE THE ABILITY TO PLACE THE TRANSMISSION INTO THE "PARK" POSITION, WITH THE RESULTING VEHICLE MOVEMENT OF AN APPARENTLY PARKED VEHICLE. PLEASE CONTACT ME ASAP. -- THANKS *TR

I HAVE A 2002 GMC ENVOY WHICH HAS A DESTROYED TRANSMISSION DUE TO THE WELL KNOWN (BUT UNBEKNOWNST TO ME) FAILURE OF THE TRANSMISSION COOLING LINES. THIS IS A CLEAR DESIGN FLAW, AS THE ROUTING IS CLOSE TO THE CATALYST. BESIDES THE OBVIOUS SAFETY CONCERNS OF AN ON THE ROAD TRANSMISSION FAILURE, THE LOCATION MAKES A FIRE LIKELY. THE DESIGN FLAW IS DOCUMENTED IN TSB PT-4722. I BELIEVE THESE VEHICLES SHOULD BE RECALLED. *TR

I WAS DRIVING HOME FROM THE BEACH (SANDY HOOK NATIONAL PARK, NJ) WHEN MY SERVICE ENGINE SOON LIGHT CAME ON. I USED ON STAR TO REMOTE DIAGNOSE THE CODE, AND WAS TOLD IT WAS AN ERROR IN MY TRANSMISSION CONTROL MODULE. I IMMEDIATELY CALLED MY NEAREST SERVICE CENTER WHO INSPECTED MY TRUCK AND INFORMED ME THAT IT WAS MY TRANSMISSION LINES THAT HAD JUST SIMPLY 'CORRODED' AND THAT MY TRANSMISSION HAS ALMOST BEEN RUNNING ON NO FLUID. THIS WAS SHOCKING CONSIDERING I MAINTAIN GOOD CARE OF MY 2002 ENVOY AND HAD SEEN NO SIGN OF LEAKING TRANSMISSION FLUID BUT WAS INFORMED IT WAS SOMEHOW ALL OVER THE BOTTOM OF MY TRUCK. THEY WERE ABLE TO FIX THE LINES FOR A COST OF 690 DOLLARS, BUT I STILL FEEL THAT SOMETHING IS NOT QUITE RIGHT WITH THIS SITUATION AND HAVE TALKED TO OTHERS WITH SIMILAR ISSUES. *TR

TRANSMISSION COOLER LINE LEAK FROM CORROSION ON 2002 GMC ENVOY. HAD TO DO SPLICE OF CORRODED SECTION AND REPLACED WITH COPPER COUPLING. *TR

VEHICLE WILL NOT MOVE WHEN PUT IN DRIVE OR REVERSE FROM PARK POSITION. AFTER SWITCHING FROM 4WD TO 2HI ETC. IT SOMETIMES WILL ENGAGE AND MOVE. IF IN FACT THE VEHICLE MOVES IT HESITATES WHEN MAKING DEEP TURNS. FOR THE MOST PART IT IS STUCK IN DRIVE AND REVERSE. TRANSFER CASE CONTROL MODULE WAS A DIAGNOSED PROBLEM BY DEALERSHIP IN 2006. NEW PART BOUGHT AND INSTALLED BY DEALERSHIP. *TR

AFTER PULLING AWAY FROM A STOP LIGHT AT A NORMAL PACE AND REACHING A SPEED OF ALMOST 50MPH THERE WAS A LOUD CLUNK AND A RRRRR SOUND COMING FROM UNDER THE VEHICLE. THE VEHICLE BEGAN TO SLOW AS THE RPM'S WENT UP, ALL FORWARD DRIVE WAS GONE. WE ALMOST GOT REARENDED... THERE WAS NO WARNING AT ALL THAT THERE WAS A PROBLEM OR WAS GOING TO BE A PROBLEM ,IT JUST BROKE..DEALER SAYS NEED NEW TRANSMISSION.. APPARENTLY GM HAS A SUN GEAR ISSUE WITH THIS TYPE OF TRANSMISSION.. *TR

MY WIFE WAS DRIVING OUR 2002 GMC ENVOY ONTO A LOCAL EXPRESSWAY WHEN SHE TRIED TO ACCELERATE, SHE HEARD A LOUD NOISE FROM THE ENGINE/TRANNY AREA, THEN NOTICED HIGH RPMS AND THE TRANSMISSION NOT SHIFTING, SHE IMMEDIATELY PULLED OVER. I CAME TO HER LOCATION AND NOTICED LOSS OF REVERSE AND A "WHINE" COMING FROM THE TRANSMISSION, THE VEHICLE WAS TOWED TO THE LOCAL GMC DEALER, THAT SAME DAY IT WAS DIAGNOSED AS THE SUN SHELL. IT APPEARS THAT THIS IS A COMMON FAILURE, I WILL BE PURSING THIS FURTHER WITH GM. *TR

TL*THE CONTACT OWNS A 2002 GMC ENVOY. THE CONTACT STATED THAT WHILE DRIVING THE VEHICLE IT WILL RANDOMLY JUMP FROM 2 WHEEL DRIVE TO 4 WHEEL DRIVE WITHOUT WARNING CAUSING THE CAR TO BECOME IDLE AND YOU MUST TURN THE CAR OFF COMPLETELY. SHE TOOK THE VEHICLE INTO A LOCAL MECHANIC WHERE HE REPLACED THE BRAKES AND CHECKED THE WHEELS AND STATED THAT THERE WAS NOTHING WRONG WITH THE VEHICLE. SHE IS ALSO EXPERIENCING PROBLEMS WITH THE FRONT PASSENGER SEAT BELT IT LOCKS WHEN FASTENED. SHE TOOK THE CAR TO THE DEALER AND THEY INFORMED HER THAT IT WAS NO LONGER COVERED UNDER WARRANTY AND ANY REPAIRS MADE WOULD BE AT THE OWNER'S EXPENSE. THE VEHICLE IS ALSO EXPERIENCING EXTERIOR LIGHT FAILURE, BOTH HEADLIGHTS BURNED OUT WITHIN WEEKS APART AND THEY WERE REPLACED AT OWNER'S EXPENSE. THE FAILURE MILEAGE WAS 38,000. THE CURRENT MILEAGE WAS 86,000 (SC) UPDATED 06/25/08. *CN...

56,779 MILE AND TRANSMISSION FAILED ON MY 2002 ENVOY. DEALER TOLD ME THEY HAD NEVER SAW THIS HAPPEN. WE HAD JUST MADE A 2300 MILE TRIP TO THE 'NO MAN LAND' OF COLORADO. THE NEXT DAY MY WIFE CAME TO A STOP SIGN, SAID THE CAR MADE A WEIRD NOISE AND WOULD NOT GO. NO REVERSE OR DRIVE BUT CRIPPLED IT HOME IN LOW. WAS VERY SURPRISED THAT THE GM DEALER WOULD NOT BACK THE TRANSMISSION. $2,903.94 TO REPLACE WITH A 1 YEAR GUARANTEE WHICH IS ABOUT UP AND I REFUSE TO DRIVE ON A LONG TRIP AGAIN IN THIS AUTO. *TR

NORMAL DRIVING CONDITIONS. EXITING FROM PARKING LOT, HEARD LOUD BANG, CAR JERKED, CAME TO A COMPLETE STOP. LIMPED CAR HOME(1/2 MILE). UPON FURTHER INSPECTION 2002 GMC ENVOY HAD NO REVERSE GEAR. RESEARCHING ONLINE SHOWS 4L60E TRANSMISSION, REACTION SUNSHELL & REACTION SUNGEARS PREMATURELY FAIL DUE TO SUBSTANDARD PARTS. *TR

TL*THE CONTACT OWNS A 2002 GMC ENVOY. WHILE MAKING A LEFT HAND TURN AT 5 MPH, THE VEHICLE MADE A WHINING NOISE AND CATAPULTED FORWARD. THE VEHICLE SHIFTED GEARS AND THE SPEED DECREASED. THE GEARS RETURNED TO NORMAL AND THE CONTACT WAS FINALLY ABLE TO PULL OVER. THE VEHICLE WAS TOWED. THE CONTACT STATED THAT THE REVERSE GEAR FAILED AND THE FIRST AND SECOND GEARS WERE BARELY FUNCTIONING. THE DEALER STATED THAT THE SUNSHELL IN THE TRANSMISSION NEEDED TO BE REPLACED IN THE TRANSFER CASE. THE PREVIOUS DAMAGES LED TO THE ENTIRE TRANSMISSION NEEDING TO BE REPLACED. THE CONTACT WAS INFORMED THAT THE VEHICLE WAS NOT INCLUDED IN NHTSA CAMPAIGN ID NUMBERS 03V075000, 01V283000, AND 01V334000. THE PURCHASE DATE WAS UNKNOWN. THE CURRENT AND FAILURE MILEAGES WERE 63,000.

2002 GMC ENVOY SLT 60K...WENT OUTSIDE TO START CAR AND HAD A LOUD SWISHING SOUND...TRIED TO PUT IN REVERSE...WOULD NOT GO...HAD TO PUSH OUT TO GET TO WORK...EXTREMELY HIGH RPMS (3500-4500) TO GET THROUGH FIRST...IT ALSO IS JUMPING GEARS...IF YOU TRY TO GO OVER 50 MPH THE CAR WILL REDLINE...WAS TOLD REVERSE REACTION SHELL/SUN SHELL GEAR...THEY HAD A BUNCH OF NAMES FOR IT...WAS DEFECTIVE AND FAILED...WE NEVER TOWED W/ THIS VEHICLE, NEVER GOT STUCK (THE GM SERVICE PRO STATED THAT THIS WAS POSSIBLY THE REASON FOR FAILURE)...THE VEHICLE IS MAYBE DRIVEN 10K MILES A YEAR...WE HAVE HAD NOTHING BUT PROBLEMS W/ THIS THING...WE ALREADY HAVE REPLACED THE CLUTCH FAN LAST YEAR...AND HAD NUMEROUS LITTLE PROBLEMS SINCE...ALL THE POSTS I HAVE READ CLEARLY SHOWS THERE NEEDS TO BE A RECALL...THE PRICES I HAVE SEEN ON POSTS IS RIDICULOUS TO REPAIR THE TRANSMISSION...$2K TO $3K...SO FOR NOW IT IS SITTING IN MY...

TRANSMISSION FAILURE AT 60,000 MILES DUE TO DEFECTIVE PARTS INSTALLED DURING THE ORIGINAL MANUFACTURING PROCESS. *TR

MANUFACTURE KNEW OF INFERIOR COMPONENTS WITHIN MY VEHICLES TRANSMISSION AND DID NOT ISSUE A RECALL. EXISTING SERVICE BULLETIN #00-07-30-022C DATED DEC 10, 2004 (WITHIN MY WARRANTY PERIOD) INDICATES SAME ISSUE I EXPERIENCED IN MY VEHICLE ON 10/23/2007. BULLETIN TITLE STATES REPLACE REACTION SUN SHELL WITH MORE ROBUST HEAT TREATED PARTS". THIS WAS KNOWN WHILE MY VEHICLE WAS STILL UNDER WARRANTY. FAILURE HAPPENED AFTER STANDARD WARRANTY EXPIRED. *TR

TRANSMISSION SUN GEAR FAILURE ON MY 2002 GMC ENVOY AT 56,000 K. GM IS ONLY PICKING UP 50% OF THE $1747.00 BILL.

MY ENVOY WAS PUT INTO PARK WHEN I WENT TO LOCK THE FRONT DOOR. WHEN I GOT OUT OF THE CAR AND TOOK TWO STEPS, IT SLIPPED OUT OF GEAR AND WENT ROLLING DOWN (VERY SLIGHT GRADE) THE DRIVEWAY IN REVERSE. I JUMPED IN TO TRY AND STOP IT BEFORE HITTING NEIGHBORS CARS. I GRABBED THE STEERING WHEEL TO PULL MYSELF IN, WHICH MADE THE ENVOY TURN TO MISS ON CAR, THEN IT THREW ME OUT, ALMOST RUNNING OVER BOTH OF MY LEGS WITH THE FRONT WHEEL. IT THEN PROCEEDED TO HIT A SATELLITE DISH, AND AIR CONDITIONING UNIT (WHICH ALL BUT RIPPED THE DOOR OFF THE HINGES.) IT THEN FINALLY STOPPED AFTER RUNNING THROUGH A FENCE AND IT RESTED WITH ONE WHEEL IN THE AIR ON A MOUND OF DIRT. *TR

DT*: THE CONTACT STATED WHILE TRAVELING 25 MPH, THE VEHICLE LUNGED, A WHIRRING NOISE OCCURRED, AND THE VEHICLE WOULD NOT ACCELERATE. IT WAS DRIVEN HOME WITH HIGH RPM'S AND LOW ACCELERATION. AT THE CONTACT'S RESIDENCE, IT WAS NOTICED THAT REVERSE DID NOT OPERATE. THE VEHICLE WAS DRIVEN TO THE DEALERSHIP, BUT WOULD NOT OPERATE ABOVE FIRST OR SECOND GEAR. THE DEALERSHIP DETERMINED THE SUN SHELL INSIDE THE TRANSMISSION FAILED AND THE TRANSMISSION NEEDED TO BE REBUILT.

I OWN A 2002 GMC ENVOY WITH 49,000 MILES. THE TRANSMISSION FAILED, DID NOT WANT TO SHIFT FROM FIRST, THEN NO REVERSE WHEN I LEFT THE DESTINATION. HAD TOWED TO DEALER. SERVICE MANAGER STATED SHE HAD A HUNCH WHAT IT WAS BUT HAD TO GET IT IN THE SHOP FIRST. SURE ENOUGH, THE SUN SHELL FAILED AND THE TRANSMISSION HAS TO BE REPLACED. CALLED GM CUSTOMER SERVICE IN AN ATTEMPT TO GET THEM TO FIX IT AT THERE EXPENSE SINCE THIS IS AN REGULAR OCCURRENCE WITH THERE TRUCKS. HAVE NOT HEARD BACK AS OF YET. SEEN MANY MANY MANY POSTS AROUND THE INTERNET ABOUT THIS VERY PROBLEM. THIS SHOULD BE LOOKED INTO. *NM

HAVE A 2002 GMC ENVOY, BOUGHT NEW. 8 RECALLS, BALL JOINT AND SPEAKER FAILURES. AT 32000. MILES, THE TRANSMISSION FAILED. DEALER DIAGNOSED WITH SUN-SHELL GEAR PROBLEM, THAT WAS ADDRESSED BY A GM REPAIR BULLETIN. AT 37000. TRANSMISSION FAILED AGAIN. DEALER ADVISED THE ENTIRE TRANSMISSION NEEDED REPLACEMENT, BUT IT WAS NOT RELATED TO HIS OCT. 05 REPAIR. CONTACTED GM CUSTOMER SERVICE, HAVE A FILE NUMBER, BUT HAVE NOT HEARD FROM ANYONE IN 2 WEEKS. THEY ADVISE THAT THE GM AREA REPRESENTATIVE HAS NOT CALLED ANYONE BACK, EITHER THE DEALER OR GM CS. ?? ASKED TO CONTACT HIM MYSELF AND WAS TOLD I COULD NOT DO THAT. ASKED WHERE I COULD CONTACT CEO RICK WAGONER AND WAS TOLD THAT NO ONE CAN GIVE OUT THAT INFO. A BUNKER IN COLARADO MAYBE? *NM

DT*: THE CONTACT STATED WHILE DRIVING 10 MPH, THE SUN SHELL GEAR FRACTURED INSIDE THE TRANSMISSION SUDDENLY, CAUSING THE TRANSMISSION TO LOSE REVERSE, SECOND AND FOURTH GEARS. THE VEHICLE WAS ABLE TO BE DRIVEN TO THE DEALERSHIP. REPAIRS HAVE BEEN MADE TO THE VEHICLE.

WENT TO BACK OUT OF NEIGHBOR'S DRIVEWAY & THERE WAS NO REVERSE GEAR; JUST LIKE IT WAS IN NEUTRAL. AFTER PUSHING THE GMC ENVOY OUT OF DRIVEWAY, IT WOULD GO FORWARD, BUT WAS VERY "STRAINED" TO GET INTO GEAR. I AM THE OWNER OF HIS ENVOY SINCE IT WAS NEW; IT HAS ONLY HIGHWAY MILES; HAS ALWAYS BEEN SERVICED BY THE DEALER FROM WHICH IT WAS PURCHASED. *JB

WE OWN A 2002 GMC ENVOY SLE, WHICH WAS PURCHASED NEW DECEMBER 2001 BY US. IN SEPTEMBER 2004 AT APPROXIMATELY 65,000 MILES THE TRANSMISSION WENT OUT. MY WIFE WAS DRIVING THE VEHICLE AT THE TIME. THE ENVOY HAS A AUTOMATIC TRANSMISSION AND 2ND GEAR AND REVERSE WENT OUT. MY WIFE WAS ABLE TO PULL OVER AND WE TOOK IT TO THE GM DEALERSHIP WHERE WE PURCHASED IT. THEY WOULD ONLY PAY 50% FOR THE REPAIR TO THE TRANSMISSION AND WE HAD TO PAY THE OTHER 50%. LESS THAN 25,000 THE TRANSMISSION HAS WENT OUT AGAIN, HAVING THE EXACT SAME PROBLEM 2ND GEAR AND REVERSE WENT OUT. AGAIN, MY WIFE WAS ON HER WAY TO WORK AND WAS ABLE TO CONTROL THE VEHICLE AND SAFELY GET IT STOPPED. WE TOOK THE VEHICLE BACK TO THE GM DEALERSHIP AND THEY ARE NOW WILLING TO REPLACE THE TRANSMISSION, HOWEVER WE HAVE TO PAY...

I OWN A 2002 GMC ENVOY WITH 70,000 MILES ON IT. WENT TO DRIVE TO THE STORE AND THE TRUCK WOULD NOT MOVE. THERE IS A WINING/ SPINNING SOUND COMING FROM THE TRANSMISSION. REVERSE WORKS, BUT ALL OTHERS DO NOT. I HAVE READ QUITE A FEW FORUMS ON THIS TOPIC AND FOUND THIS PROBLEM HAPPENS OFTEN. PLEASE LET ME KNOW WANT I COULD DO ABOUT THIS. *NM

DROVE VEHICLE AS NORMAL WITHOUT WARNING AND AFTER I STOPPED (SHUTDOWN THE VEHICLE AND RESTARTED IT) THERE WAS NO REVERSE GEAR OR FORWARD GEAR. VEHICLE WAS TOWED TO THE DEALER WHERE I WAS LATER TOLD THAT THE REVERSE GEAR HAD BLOWN APART. DAMAGED PARTS WERE REPLACED AND TRANSMISSION WAS FLUSHED AND REFILLED. I'M CONCERNED NOW BECAUSE THE VEHICLE IS OUT OF WARRANTY AND IT IS SLUGGISH OR SLIPPING WHEN IT MAKES A 1ST TO 2ND SHIFT. WILL IT REQUIRE ADDITIONAL TRANSMISSION WORK IN THE NEAR FUTURE AND HUGE $$ TO REPAIR? *NM

I OWN A 2002 GMC ENVOY THAT I PURCHASED NEW IN FEBRUARY 2002. ON 24 MAY 2005, THE TRANSMISSION FAILED WITH 68,920 MILES ON THE ODOMETER. THERE WAS NO REVERSE OR DRIVE. THE VEHICLE OPERATED MARGINALLY IN GEARS 3,2,AND 1---ENOUGH TO LIMP INTO THE DEALER. LUCKILY, IT DIDN'T FAIL ON THE HIGHWAY...OR I MIGHT NOT BE HERE WRITING THIS COMPLAINT! AFTER TEARING DOWN/CHECKING OUT THE TRANSMISSION, THE TECHNICIAN FOUND A DAMAGED SUN REACTION SHELL AND SUN GEAR. THE PARTS WERE REPLACED, ALONG WITH NEW GASKETS AND SEALS, THE TRANSMISSION CLEANED AND POWER FLUSHED. THE TOTAL COST OF THIS EFFORT WAS $2277. :-( :-( IN DOING A BIT OF RESEARCH ON THIS PARTICULAR FAILURE, I'VE DISCOVERED OTHER GMC ENVOY, OLDSMOBILE BRAVADA, AND TRAIL BLAZER OWNERS HAVE BEEN VICTIMS TOO. ACCORDING TO ONE OF THEM, WHO WORKS IN THE SERVICE DEPARTMENT OF A GM DEALER, THE REPAIR INSTRUCTIONS STATE THE MATERIAL USED...

DRIVING DOWN A 4 LANE INTERSTATE AT 65 WITH CRUISE ON, THE TRANSMISSION STARTS TO WINE AND LOSES ACCELERATION. MOVED OVER TO SLOW LANE PROCEEDED TO GET THE NEXT 35 MILES HOME IN 3RD GEAR (NOISE WAS MAKE IN "D"). UPON ARRIVAL HOME-FOUND OUT THAT THE ENVOY NO LONGER HAS REVERSE. DEALER BELIEVES THERE IS A PROBLEM WITH THE "SUN PLATE" IN THE TRANSMISSION. THIS ENVOY ONLY HAS 48,300 MILES. DEALER BELIEVES THIS IS THE PROBLEM BECAUSE HE HAS SEEN THIS BEFORE AND KNOWS THERE IS A PROBLEM. WHY IS THERE NOT A RECALL ON THIS PART OR PROBLEM?? THIS SHOULD NOT BE HAPPENING WITH ANY VEHICLE THAT HAS SUCH LOW MILES. *NM

DT: CONTACT STATED TRANSMISSION WENT OUT AT AROUND 29,415 MILES. TRANSMISSION FAILED WHILE DRIVING AT 20 MPH, AND LEAVING HIM STRANDED. TRANSMISSION HAS BEEN REPAIRED. THE SERVICE DEALER REPLACE THE SUN GEAR, AND STATED THIS WAS A KNOWN PROBLEM WITHIN THE GMC ENVOY. *AK *JB

BACKING UP MY DRIVEWAY AND HEARD A "CLUNK" FOLLOWED BY A HIGH PITCHED WHINING NOISE. FOLLOWING THIS, I HAD NO REVERSE AND THE TRANSMISSION FAILED.

WHILE TAKING OFF FROM A COMPLETE STOP, THE TRANSMISSION LUNGED AND SUDDENLY I HAD NO DRIVE OR THIRD GEAR. I WAS ABLE TO COAST TO THE SIDE OF THE ROAD PUT THE TRUCK IN PARK BUT THE GEAR WOULD NOT RE-ENGAGE. THE TRUCK WAS TURNED OFF AND CRANKED AGAIN, STILL NO DIFFERENCE. HOWEVER, I DID HAVE SECOND AND FIRST GEAR. WHILE DRIVING IN SECOND GEAR AT A VERY LOW SPEED THE VEHICLE WAS TRANSPORTED TO DEALERSHIP. SERVICE PERSONNEL ADVISED THE TRANSMISSION WAS GONE AND WOULD COST $3400.00 TO REPLACE. HE STATED THE GEARS WERE BROKEN OFF INSIDE THE TRANSMISSION AND THE OIL WAS BURNT. HE ADVISED THE VEHICLE ONLY HAS 36,000 MILES / 3 YEARS WARRANTY ON THE POWER TRAIN - TRANSMISSION, WHICH EVER CAME FIRST. I HAVE LESS THAN 74,000 MILES ON MY TRUCK.

WAS HEARING A CLUNKING NOISE WHEN SHIFTING FROM PARK INTO DRIVE. EVENTUALLY WENT TO SHIFT INTO DRIVE AND IT FELT LIKE I RAN OVER SOMETHING, BUT NOTHING WAS THERE. THEN THE TRUCK WOULD NOT SHIFT INTO SECOND OR FOURTH AND LOST REVERSE ALL TOGETHER. WAS TOLD THE TRANSMISSION IS BLOWN.

WHILE CRUISING AT HIGHWAY SPEED (65 MPH) MY 2002 GMC ENVOY SUDDENLY MADE A LOUD CRUNCHING NOISE AND LOST FORWARD MOTION. THE ENGINE REVVED UP, THEN DOWN, THEN TURNED OFF (WHILE MULTIPLE DASH WARNING LIGHTS CAME ON SIMULTANEOUSLY). I MANAGED TO GET THE VEHICLE OFF THE ROAD WITHOUT THE HELP OF POWER STEERING OR BRAKES, AND AFTER A FEW MINUTES I STARTED IT BACK UP AND FOUND I COULD DRIVE OFF ONLY AT LOW SPEED ON THE SHOULDER, THOUGH THERE WAS CONTINUED NOISE FROM THE UNDERSIDE OF THE CAR AND IT WAS ERRATICALLY PERFORMING. I IMMEDIATELY BROUGHT THE CAR TO A MECHANIC WHO DISCOVERED THAT INTERNAL PARTS IN THE TRANSMISSION HAD FAILED. THE MECHANIC ALSO INFORMED ME THAT THERE IS A GMC TECHNICAL SERVICE BULLETIN ABOUT THIS AND IT IS A COMMON/FREQUENT PROBLEM. THE TSB RECOMMENDS REPLACING THE INTERNAL TRANSMISSION PARTS. THE MECHANIC SAYS THAT REPLACING THE TRANSMISSION IS THE...

WHILE DRIVING THE VEHICLE, I STEPPED ON THE GAS AND IT ONLY INCREASED THE RPM AND DID NOT PROVIDE ANY ACCELERATION WHILE CHAGING LANES. IT THEN LATER KICKED IN AND I GOT ACCELERATION. WHEN I PARKED THE VEHICLE TO SEE CHECK THINGS OUT, I WAS UNABLE TO USE REVERSE TO GET OUT OF THE PARKING SPACE, REVERSE NO LONGER WORKED. AFTER THE INCIDENT OCCURED, I CHECKED OUT OWNER FORUMS ONLINE TO FIND THAT MANY OWNERS HAVE HAD SIMILAR PROBLEMS.

ON DEC. 3, 2003, I TOOK MY 2002 ENVOY INTO THE DEALERSHIP BECAUSE I WAS EXPERIENCING SERIOUS SHIFTING ISSUES. REPEATEDLY MY CAR WOULD SHIFT WHILE I WAS DRIVING BETWEEN 2WD AND 4 WD HI. THE CAR WOULD ALSO WOULD MAKE CHUGGING NOISES. FURTHERMORE, THE VEHICLE SHIFTED BETWEEN GEARS ON ITS OWN WHILE I WOULD BE MAKING SHARP TURNS SUCH AS INTO A PARKING SPACE. WHILE IN PARK, IF I DID NOT HAVE MY FOOT ON THE BRAKE PETAL, THE CAR WOULD JUMP FORWARD. THE CAR ALMOST JUMPED THROUGH A STORE FRONT WINDOW. THE DEALER COULD FIND NOTHING WRONG WITH MY CAR. I TOLD THEM TO KEEP IT ANOTHER DAY, THAT THERE WAS SOMETHING SERIOUSLY WRONG WITH THE CAR. THE DEALER KEPT THE CAR ANOTHER DAY, AND STILL FOUND NOTHING. ON DECEMBER 31, 2003, I CONTINUED TO EXPERIENCE THE AFOREMENTIONED PROBLEMS. KNOWING THAT IT WAS NEW YEAR'S EVE AND THAT THE...

I HAVE HAD MULTIPLE ELECTRICAL AND TRANSMISSION PROBLEMS WITH MY 2002 GMC ENVOY. YESTERDAY MY FAMILY AND I WERE DRIVING ON INTERSTATE 80, WHILE ON CRUISE CONTROL, THE SUV SHUT OFF. I BARELY WAS ABLE TO GET TO THE SIDE OF THE ROAD. I ALMOST HIT A VEHICLE GETTING OFF THE HIGHWAY SINCE I LOST POWER STEERING. AFTER 15 MINUTES OF NOT STARTING, IT FINALLY STARTED. I TOOK THE VEHICLE TO THE DEALERSHIP AND THEY COULDNT FIND ANYTHING. I HAVE WRITTEN MANY LETTERS AND TRIED TO CONVINCE GMC THAT THIS SUV IS NOT SAFE.

TRANSMISSION SLIPS GEARS WHILE DRIVING. DEALER WILL REPAIR THE TRANSMISSION, BUT HAS NOT INFORMED THE CONSUMER EXACTLY WHAT COMPONENT FAILED. *AK

MY 2002 ENVOY EXHIBITS THE SAME SYMPTOMS AS MY PREVIOUS GMC JIMMY. IT HAS A HESITATION ON ACCELERATION THAT FAILS TO SHIFT FROM 1-2 PROPERLY. THIS ONLY OCCURS WHEN THE CAR IS COLD AND ONLY FOR A MILE OR TWO. HOWEVER , IT CAUSES SEVERE LOSS OF POWER AND ACCELERATION CAPABILITY. OBVIOUSLY OTHER PEOPLE HAVE THIS PROBLEM BUT IT DOES NOT APPEAR THAT THERE IS A SOLUTION. IT ALWAYS WORKS BY THE TIME IT GETS TO THE DEALER, OF COURSE. *NLM

TRANSMISSION DOES NOT WORK PROPERLY. HAVE HAD IT REPAIRED TWICE, BUT STILL VIBRATES, AND FAILS TO MOVE VEHICLE FORWARD AT TIMES, FROM A DEAD STOP. IS VERY DANGEROUS AT INTERSECTIONS WHERE MOVING QUICKLY IS IMPERATIVE. ALSO WIRING PROBLEMS WHICH OPERATE VARIOUS REMOTE INSTRUMENTS (MIRRORS, SEATS, ETC.) FEAR OF FIRE. REAR DOOR LATCH WAS REPLACED - CLICKS "LOCKED/UNLOCKED" WHILE DRIVING. SEATS MOVE ON THEIR OWN WHILE DRIVING. *NLM

CONSUMER WAS UNABLE TO SHIFT THE GEAR FROM PARK TO DRIVE. *JB

COMPLAINT IS FOR 2002 GMC ENVOY. ON THREE OCCASIONS, THIS TRUCK STALLED OUT WHILE IN MOTION, THE LAST TIME AT 55 MPH ON AN INTERSTATE HIGHWAY. ON THREE OCCASIONS, THE TRANSMISSION IN THIS VEHICLE SWITCHED, OF ITS OWN ACCORD, FROM 2 WD TO 4 WD (LOW) NEARLY CASUSING ACCIDENTS ON TWO OCCASIONS. I LISTED THE MOST RECENT OCCURRENCES OF THESE PROBLEMS BELOW.

TRANSMISSION ON COLD START STAYS IN FIRST GEAR. LEFT REAR BRAKE APPEAR TO HAVE HUNG UP AND IS BURNING. DT

ALL THESE PROBLEMS COME AND GO, SOMTIMES DEPENDING ON THE OUTSIDE TEMPERATURE. SOME OF IT GOT FIXED AND CAME BACK AGAIN. THE MAJOR PROBLEMS ARE THAT THE VEHICLE SHUTS DOWN WITHOUT ANY WARNING - NO ENGINE NO ELECTRIC NOTHING-, SO ITS EVEN NOT POSSIBLE TO CALL ON STAR! THE OTHER THING IS THAT THE TRANSMISSION START TO SHIFT GEARS WHILE DRIVING ON A LEVELED RAOD AT CONSISTANT SPEED. ALL THIS ITEMS GOT FIXED AND COME BACK AFTER A WHILE. DT

ENGINE STALLS FOR NO APPARENT REASON. I HAVE CONTACTED DEALERSHIP AND THEY CAN FIND NOTHING WRONG. I ADVISED THEM OF A RECALL REGARDING THE FUEL SYSTEM THAT MAY AFFECTED THE PROBLEM. SAYS THEY REPLACED THE FUEL FILTER. THE FIRST TIME I TOOK IT IN, THEY SAID THAT IT WAS THE IGNITION SWITCH. ALSO TRANSMISSION MAKES A VERY LOUD NOISE WHEN ATTEMPTING TO TAKE OFF AT TIMES. IT SOUNDS LIKE AN ENGINE FAN THAT WILL NOT GO OFF. THERE IS A MAJOR LOST OF POWER WHEN THIS PROBLEM IS OCCURING. I BOUGHT THIS CAR AS A PROGRAM CAR, WITH @ 11, 000 MILES ON IT ALREADY. I'VE HAD PROBLEMS WITH IT FROM DAY ONE. I HAVE ONLY HAD IT A FEW MONTHS. I AM EXTREMELY IRRITATED WITH THIS ENGINE PROBLEM. THIS IS EXTREMELY UNSAFE. DT

CONSUMER STATES THE VEHICLE WILL SLIP OUT OF OVERDRIVE AND INTO FIRST GEAR, WHICH RESULTS IN THE VEHICLE LOSING POWER. THERE IS A WARNING LIGHT THAT WILL COME ON WHICH WILL READ REDUCE ENGINE SPEED, THE DEALER REPLACED THE PCM/VCM BUT THIS DID NOT CORRECT THE PROBLEM, FRONT END SQUEAKS WHEN TURNING AND DRIVING, . MR *NLM *DT

WHILE TOWING VEHICLE IN NEUTRAL, TRANSMISSION SLIPPED OUT OF GEAR AND A FIRE STARTED IN TRANSMISSION AREA. CONTACTED DEALER WHO WAS NOT WILLING TO DO ANYTHING.*AK CONSUMER STATES THAT THE TRANSFER CASE SHIFT MODULE FAILED TO ENGAGE NEUTRAL, CONSUMER HAD BRACKETS AND WIRING INSTALLED TO ACTIVATE THE BRAKE AND TAIL LIGHTS WHEN BEING TOWED, THERE IS A RECALL, 01V334, REGARDING TRANSFER CASE CONTROL MODULE PROBLEMS, HOWEVER THIS VIN IS NOT INCLUDED. *SLC

WE PURCHASED NEW VEHICLE OCTOBER 2001 AND WITHIN 4 MONTHS BEGAN EXPERIENCING PROBLEMS BEGINNING WITH A NOISE WITHIN THE STEERING WHEEL. DEALER TECHNICIAN REPLACED DEFECTIVE AIRBAG MODULE. THE NEXT MONTH, MY NEW ENVOY HAS BEEN TO THE DEALER 4 TIMES FOR THE SAME PROBLEM OF 1) WIND AND/OR WHISTLING NOISE AT SPEEDS ABOVE 45MPH, 2) "VIBRATION" NOISE COMING FROM TRANSMISSION WHEN VEHICLE REACHES 3RD GEAR , 3) WHEN VEHICLE HAS REACHED 3RD GEAR AND PREVIOUS NOISE BEGINS, THERE IS ALSO A VIBRATION FELT IN THE ACCELERATION PEDAL. ON THE FIRST TRIP TO DEALER FOR THESE PROBLEMS, TECHNICIAN ONLY AGREED WITH THE WIND NOISE. DISCOVERED THE FRONT SIDE MIRRORS WERE THE CAUSE. REPLACED BOTH MIRRORS---PROBLEM STILL EXISTS, HOWEVER, HE CAN'T HEAR THEM. EXPLAINED IT WAS THE NATURE OF THE VEHICLE. HE ALSO REPAIRED THE WEATHERSTRIPPING WHICH HAD "FALLEN OFF" THE RIGHT REAR DOOR. HE ADVISED THAT HE DID NOT HEAR ANY...

MIRRORS 'WANDER' EVERY TIME VEHICLE IS UNLOCKED, FAIL TO RETURN TO SETTINGS CREATING AN UNREASONABLE DANGER TO THE OCCUPANTS OF THIS VEHICLE AS WELL AS OTHER VEHICLES WHEN CHANGING LANES OR MERGING INTO TRAFFIC DUE TO LACK OF VISABILITY OF THE AREA BEHIND THE VEHICLE. TRANSMISSION FAILED ON A SLIGHT INCLINE WITH PARKING BRAKE ENGAGED AND TRANSFER CASE LOCKED AND IN 4WD AND TRANSMISSION IN PARK - VEHICLE BEGAN ROLLING BACKWARDS DOWN THE SLIGHT GRADE. THERE WAS A RECALL FOR THIS PROBLEM - CAMPAIGN WAS COMPLETED AT DEALER, BUT FIX IS UNKNOWN TO THE OWNER.

TRANSMISSION DOES NOT SEEM TO DOWNSHIFT; LOUD FAN NOISE WITH LOSS OF POWER; HARD SHIFT INTO GEAR FROM START; MISSING REAR SEAT LATCH TO HOLD DOWN SEAT AND EASILY WOBBLES WHEN SHAKEN; HOOK FOR LATCH IS PRESENT BUT NO LATCH PRESENT SEEMS TO BE DESIGN FLAW. *AK

WHILE DRIVING, CAR SUDDENLY SHUT DOWN COMPLETELY WITH NO WARNING. SECOND PROBLEM: TRANSMISSION FAILED WHILE TOWING 3300 LBS OR LESS ON TWO SEPARATE OCCASIONS. *AK

SERVICE ENGINE LIGHT ILLUMINATES, ENGINE COOLING FAN ENGAGES, ENGINE POWER GREATLY REDUCES AND TRANSMISSION SHIFTS IMPROPERLY. LOUD NOISE FROM COMPUTER CONTROLLED ENGINE COOLING FAN. VEHICLE WILL NOT ACCELERATE OR SHIFT PROPERLY WHEN DRIVING WITH FAULT. FAN CLUTCH REPLACED, COMPUTER PROGRAMMING CHANGED WITH NO SUCCESS OF FIXING PROBLEM. GMC REFUSES TO BUY BACK VEHICLE. DEALERSHIP INDICATES THIS PROBLEM IS OCCURRING ON ALL 2002 GMC ENVOY'S AT VARYING LEVELS MINE BEING WORSE CASE. VEHICLE IS UNSAFE FOR USE IN ANY TRAFFIC SITUATION AS THE PROBLEM MANIFEST ITSELF RAPIDLY WITH SEVERE LOSS OF ENGINE POWER, LOUD NOISES FROM ENGINE AND POOR SHIFTING AND ACCELERATION.*AK
