2008 GMC ACADIA Power Train Problems

THE TRANSMISSION WOULD NOT SHIFT INTO THIRD GEAR. TOOK TO DEALER. THEY WERE AWARE OF THE PROBLEM AND "OFFERED TO HELP" BY DISCOUNTING THE PRICE OF REBUILDING THE TRANSMISSION. THE TRANSMISSION IS STILL NOT RIGHT. SHIFTING IS POOR AND CLUNKY. *TR

THE TRANSMISSION IN OUR 2008 ACADIA HAS BEGUN SLIPPING AND FIRST GEAR SHIFTS ENGAGE WITH A VERY NOTICEABLE CLUNK (THUMP); THERE IS ALSO A DELAY WHEN THE CAR IS SHIFTED INTO DRIVE (~3 TO 5 SECONDS); GM NEEDS TO PERFORM. *TR

DRIVING ON INTERSTATE AT 75 MPH. CAR SUDDENLY LOST POWER AND SLOWED IMMEDIATELY. HAD TO CROSS LANE IN HEAVY TRAFFIC TO GET TO SIDE OF ROAD. LUCKILY DID NOT GET HIT. HAD WIFE AND DOG ALONG. STUCK ON SIDE OF ROAD IN COLD WEATHER FOR OVER AN HOUR. SUDDEN LOSS OF POWER ON BUSY INTERSTATE WAS VERY DANGEROUS. IN READING FORUMS ON INTERNET, THIS APPEARS TO BE COMMON PROBLEM. GMC NEEDS TO TAKE RESPONSIBILITY FOR THIS COMMON DEFECT. *TR

COMPLETE TRANSMISSION FAILURE. FLUID WAS CHECKED AND FULL AFTER FEELING THE TRANSMISSION SLIP MOMENTS BEFORE. TURNED TO GO BACK HOME AND THE VEHICLE LOST POWER. THANKFULLY WE WERE NOT YET ON THE INTERSTATE AND COASTED OFF THE ROAD. VEHICLE WAS TOWED TO DEALERSHIP WHERE IT WAS CONFIRMED THAT THE TRANSMISSION WAS RUINED AND TOTAL REPLACEMENT WAS REQUIRED AT A COST OF $4200. AFTER READING ABOUT THE MANY ISSUES WITH THIS VEHICLE AND SPEAKING TO A MECHANIC WHO SAID THEY WERE ALWAYS FIXING MAJOR ISSUES WITH THIS MODEL/YEAR WE OPTED TO TRADE INSTEAD. DIDN'T WANT TO INVEST THAT AMOUNT OF MONEY AND ALWAYS BE WAITING FOR THE NEXT ISSUE TO ARISE. *TR

WHILE DRIVING OUR GMC ACADIA WE HAD LOST OUR TRANSMISSION WITH NO WARNING. WE WERE 300 MILES FROM HOME AND HAD TO HAVE THE VEHICLE TOWED BACK TO OUR HOME SO WE COULD FIGURE OUT WHAT HAD HAPPENED. UPON DOING RESEARCH WE HAD LEARNED THAT THE WAVE PLATE INSIDE THE TRANSMISSION HAD BROKE AND DESTROYED THE TRANSMISSION WITH KNOW WARNING SIGN. FORTUNATELY ENOUGH I HAD JUST EXITED THE FREEWAY TO PULL INTO A SHOPPING CENTER FOR REST. THE POTENTIAL FOR THIS PROBLEM TO HAPPEN WHILE ON THE FREEWAY WOULD HAVE HAD A MUCH WORSE OUTCOME AND HAD THE POTENTIAL TO BE VERY DANGEROUS TO ME AND MY FAMILY. I HAVE LEARNED THROUGH RESEARCH THAT GM IS AWARE OF THE PROBLEM AND HAS REFUSED TO RECALL THE VEHICLE TO REPAIR THIS ISSUE. THIS IS NEGLIGENCE ON GM'S PART AS THEY WERE ADVISED BY THEIR OWN ENGINEERS TO USE A $30 WAVE...

VEHICLE RPM'S WOULD START GOING UP AND DOWN. THEN THERE WOULD BE HESITATION WHEN YOU ACCELERATED. I PULLED OUT FROM DOCTOR'S OFFICE AND IT WOULD NOT MOVE IN REVERSE OR FORWARD. CAR HAD TO BE TOWED TO A LOCAL MECHANIC. *TR

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT THE VEHICLE SUDDENLY FAILED TO ACCELERATE. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS FOUND THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED ABOUT THE FAILURE. THE FAILURE MILEAGE WAS 59,000...UPDATED 12-30-13 *BF UPDATED 1/22/2014 *JS

I WAS DRIVING HOME WHEN MY TRANSMISSION SUDDENLY STARTED TO LURCH AND HUNT FOR GEARS, THEN HESITATE. MY CAR THEN WOULDN'T MOVE FORWARD NOR WOULD IT GO INTO REVERSE. TWO CODES SHOWED UP WHEN I HAD THE VEHICLE SCANNED, P2715 AND P0700. AFTER DOING RESEARCH I CONCLUDED THE WAVE PLATE IN MY TRANSMISSION HAD FAILED. MY VEHICLE IS NO LONGER DRIVABLE. THANKFULLY I WASN'T ON THE FREEWAY WHEN THIS INCIDENT HAPPENED BECAUSE ONCE THE TRANSMISSION QUIT THE VEHICLE CAME TO A STOP RATHER QUICKLY. IN READING REPORTS ONLINE IT APPEARS TRANSMISSION FAILURE OF THIS PARTICULAR MODEL IS HIGHLY PROBABLE AND THAT GM KNOWS IT'S AN ISSUE BUT HAS REFUSED TO RECALL THE VEHICLE. *TR

WHILE MERGING ONTO THE HIGHWAY THE VEHICLE WAS REVVING UP, BUT NOT SPEEDING UP. I WOULD TAKE MY FOOT OFF THE ACCELERATOR FOR A SECOND AND THEN TRY TO ACCELERATE AGAIN. THE GEAR WOULD SOMETIMES "CATCH" AND SOMETIMES NOT "CATCH". THE MECHANIC DISCOVERED THAT THE ONE COOLING LINE WAS CORRODED AND ANOTHER WAS "SWEATING". THE TRANSMISSION, TORQUE CONVERTER, AND COOLING LINES ALL HAD TO BE REPLACED. I THINK ITS A PREMATURE TIME FOR MY VEHICLE TO NEED A NEW TRANSMISSION WITH ONLY 76K MILES AS THE VEHICLE IS WELL MAINTAINED. *TR

I JUST HAD MY TRANSMISSION FAIL ON ME YESTERDAY. LUCKILY IT STILL HAD 1ST & 2ND GEAR, UNFORTUNATELY I'M 5YR-8MONTHS INTO IT AT 58XXX MILES. SOUNDS LIKE I'LL BE PAYING FOR THIS ONE. IF THERE IS ANY INFO OUT THERE ON RECALLS . FROM WHAT I'VE BEEN READING ONLINE, IT SEEMS THERE IS A REAL PROBLEM WITH THIS TRANSMISSION (6T70) IN THE EARLY YEARS. I IMAGINE AS MORE AND MORE '07 - '09 ACADIAS (TRAVERSE, ENCLAVES & VUES) GET INTO THE 50K+ MILE RANGE THE TRANSMISSION PROBLEMS ARE REALLY GOING TO START SPIKING UP. IT WOULD BE A REAL SHAME IF GM CHOOSES TO IGNORE THE OBVIOUS AND PUSH THIS PROBLEM BACK ON TO THEIR CUSTOMERS. *TR

I PURCHASED A USED 2008 GMC ACADIA IN DECEMBER 2012. AT TIME OF PURCHASE, THE VEHICLE CAR FAX REPORT WAS CLEAN AND INDICATED ONE PREVIOUS OWNER. THE VEHICLE MILEAGE AT THE TIME OF PURCHASE WAS APPROXIMATELY 81,000 MILES. MY PERSONAL MECHANIC INSPECTED THE VEHICLE PRIOR TO PURCHASE AND ALSO GAVE THE VEHICLE A CLEAN REPORT. FOR THE FIRST 11 MONTHS OF OWNERSHIP, THIS VEHICLE RAN LIKE A CHAMP. TODAY, AT 99,728 MILES (MOSTLY HIGHWAY MILEAGE ON MY BEHALF) I FIND THAT I AM HAVING TO REPLACE THE ENTIRE TRANSMISSION (REBUILD) AT AN OUT-OF-POCKET EXPENSE OF $4,300. I CALLED THE GMC DEALER WHERE I PURCHASED THIS VEHICLE AND THEY ADVISED THAT THERE WERE NO RECALLS/WARRANTIES AVAILABLE ON THE TRANSMISSION. THEY ALSO ADVISED THAT IN THE EVENT THE ENTIRE TRANSMISSION NEEDED REPLACED, THAT THE COST WOULD BE IN THE VICINITY OF $4,500 AND THEY WERE ABLE TO PROVIDE THIS ESTIMATE WITH CERTAINTY...

I WAS DRIVING ON A MAJOR HIGHWAY. THE CAR WOULD NOT CHANGE GEARS TO ACCELERATE. WHEN I GOT HOME THE CAR WOULD BARELY MOVE WHEN I TRIED TO BACK INTO MY DRIVEWAY. THE ENGINE REVVED AS IF THE CAR WAS IN NEUTRAL. THIS TRANSMISSION FAILURE COULD HAVE CAUSED A SERIOUS OR FATAL ACCIDENT, AS THE SPEED LIMIT WAS 55 AND I HAD NO WARNING THAT THE CAR WOULD NOT ACCELERATE WHEN EXPECTED. *TR

I WAS TURNING LEFT AT STOP LIGHT. THE TRANSMISSION FAILED TO SHIFT AND STALLED CAUSING ME TO BE STRUCK. THIS COULD HAVE BEEN A FATALITY IF TRAFFIC WERE HEAVIER. I HAVE SINCE RESEARCHED AND FOUND THAT GM HAS HAD THOUSANDS OF COMPLAINTS REGARDING THE TRANSMISSION PROBLEMS. THIS COULD HAVE BEEN PREVENTED HAD GM RECALLED A DEFECTIVE VALVE LOCATED IN THE SIDE BOX (ACCORDING TO MECHANIC AT GM DEALER THIS IS WHY I STALLED OUT). I AM SEEKING AN ATTORNEY FOR A CLASS ACTION LAWSUIT. *TR

3/5/R WAVE PLATE TRANSMISSION FAILURE - I WAS TRAVELING OUT OF STATE AND MY 2008 GMC ACADIA STOPPED IN IT'S TRACKS WITHOUT ANY WARNING. VEHICLE WAS RUNNING, BUT IT WOULD NOT MOVE. I WAS STRANDED ON THE SIDE OF THE ROAD, AT NIGHT WITH 3 YOUNG CHILDREN, OVER 5 HOURS AWAY FROM HOME. VEHICLE WAS TOWED TO THE DEALERSHIP THE NEXT MORNING AND 3/5/R WAVE PLATE FAILURE WAS DETERMINED, NEW TRANSMISSION REQUIRED. LESS THAN A WEEK PRIOR TO THE CROSS COUNTRY TRIP, VEHICLE WAS AT DEALERSHIP HAVING OIL CHANGE AND OTHER PREVENTATIVE MAINTENANCE COMPLETED, NO ISSUES NOTED AT THAT TIME. MAJOR SAFETY ISSUE THAT NEEDS TO BE INVESTIGATED. *TR

TRANSMISSION WENT OUT WHILE DRIVING ON THE INTERSTATE. WE WERE ABLE TO PULL-OVER AND GET OUT OF THE WAY OF THE HIGH SPEED TRAFFIC. NO ACCIDENT OCCURRED, BUT IT COULD HAVE BEEN A SERIOUS SITUATION THAT CAUSED SEVERAL ACCIDENTS. *TR

TRANSMISSION STOPPED WORKING AND WONT LET THE VEHICLE MOVE. THIS VEHICLE ONLY HAS ABOUT 57,000 MILES! BY READING ON THE INTERNET IT SEEMS I'M NOT THE ONLY ONE WITH THIS ISSUE. GM HAS NOT ISSUED A RECALL ON THIS YET. *TR

I NOTICED THAT THE GEARS FELT LIKE THEY WERE SLIPPING. RPMS WOULD GO UP BY 1000-1500, THEN THE VEHICLE WOULD ENGAGE IN GEAR. I NOTICED THIS VERY SPORADICALLY A FEW DAYS BEFORE I TOOK THE CAR IN, BUT IT STEADILY GOT WORSE. I CALLED THE DEALER AND PARKED THE CAR UNTIL MY SERVICE APPOINTMENT EVEN THOUGH THERE WERE NO WARNING LIGHTS ON THE CAR. AFTER MAKING THE SERVICE APPOINTMENT, I RESEARCHED ACADIA TRANSMISSION ISSUES ON THE WEB, AND FOUND LOTS OF COMPLAINTS ABOUT THE 35R WAVE PLATE. TURNED OUT THIS WAS THE SOURCE OF MY ISSUE AS WELL. TRANSMISSION HAD TO BE COMPLETELY DIS-ASSEMBLED TO CLEAN OUT THE DEBRIS. TOTALLY UNACCEPTABLE FOR A 5.5 YEAR OLD CAR WITH LESS THAN 80K MILES TO NEED ITS TRANSMISSION REBUILT. GIVEN THE NUMBER OF COMPLAINTS ABOUT THE 35R WAVE PLATE, PLEASE OPEN AN INVESTIGATION FOR A RECALL. *TR

I WAS DRIVING BY MYSELF WITH MY 3 CHILDREN WHEN MY TRANSMISSION WENT OUT. I HAVE KEPT UP WITH ALL MAINTENANCE AND EVEN HAD A TRANSMISSION FLUSH DONE 4 MONTHS AGO, JUST TO HAVE THE TRANSMISSION GO ANYWAY. GMC CUSTOMER SERVICE WILL NOT HELP (THE CAR IS ONLY 5 YEARS OLD) BUT SAID IT WAS IN SERVICE IN 2007, SO NO WARRANTY COVERAGE. THERE ARE SEVERAL HUNDRED COMPLAINTS ON THE SAME ISSUE WITH NO ONE WILLING TO DO THE DECENT OR RIGHT THING. THERE SHOULD BE A RECALL. WE HAVE HAD SEVERAL ISSUES WITH THIS VEHICLE. WE HAVE FOUR CHILDREN SO WE NEED THIS CAR. WE CANNOT AFFORD TO PAY THOUSANDS OF DOLLARS TO HAVE SOMETHING FIXED THAT IS AN OBVIOUS ONGOING ISSUE WITH THESE VEHICLES. PLEASE CONSIDER INVESTIGATING THIS. THIS TRULY IS AN ISSUE THAT GMC SHOULD BE ACCOUNTABLE FOR. *TR

HAD A COMPLAINT WITH THE TRANSMISSION NOT DOWNSHIFTING ADEQUATELY ON 10-25-2010 AND COURTESY GMC REPROGRAMMED IT ... UNDER WARRANTY. FOR ABOUT A WEEK PRIOR TO 10-22-13 THE CAR WAS NOT DRIVING RIGHT WITH THE SHIFTING ACTING UP SO I BROUGHT IT IN AND AS I WAS IN THE PROCESS OF GETTING MY CAR TO A SERVICE CAR CENTER IT WOULD QUIT RUNNING, BUT I GOT IT IN THE SHOP IN TIME BEFORE IT STOPPED FOR A THIRD TIME. IT ACTED UP ON HIGHWAY 90 WHILE DOING 57MPH AND AGAIN AT DOING 45MPH AND WHEN I SLOWED DOWN TO TURN INTO THE SERVICE CENTER. THE SERVICE CENTER (DAVE'S), AFTER CHECKING IT OUT, BROUGHT IT IN TO A-ABAL TRANSMISSION FOR ME SINCE I WAS AFRAID TO DRIVE IT IN CASE IT DIDN'T MAKE IT. MY TRANSMISSION HAD TO BE COMPLETELY REBUILT ($4205) AT MY EXPENSE (HAD MULTIPLE BROKEN PARTS) SINCE MY WARRANTY...

GMC ACADIA, CATASTROPHIC ENGINE FAILURE, AND STEERING SYSTEM. 23 SEPT 2013, WHILE DRIVING MY GMC ACADIA, AND THE VEHICLE SHUT OFF AFTER A LOUD NOSE CAME FROM THE ENGINE, TUESDAY 24, 2013, SUV TOWED TO PRIVATE REPAIR SHOP. AFTER ATTEMPTING TO START THE VEHICLE AND CHECKING THE SUV OUT, I WAS TOLD THAT THEY WOULD NOT GO FURTHER BECAUSE THEY BELIEVE THE VEHICLE NEEDS A NEW ENGINE, I CALL GMC AND TALKED WITH [XXX] A PROBLEM SPECIALIST, ARRANGEMENTS FOR VEHICLE TO BE CHECK OUT AT ?HENNESSEY GMC. POC, [XXX], I HAVE MET WITH BEFORE IN REGARDS TO A RECALL, AND TOLD HIM ON MULTIPLE OCCASIONS THAT I HEARD SOME SOUNDS COMING FROM THE ENGINE, I WAS TOLD THEY DID NOT HEAR ANYTHING. 25 SEPT 2013 SUV LEFT AT SHOP, [XXX]WOULD CALL ME THAT DAY. I DIDN'T HEAR FROM HIM, 1 OCT 2013 I STOP BY HENNESSEY, ON THE SUV'S PROBLEM,...

WAVE PLATE TRANSMISSION FAILURE 2 MONTHS AFTER PURCHASE AND 5 MONTHS AFTER WARRANTY. SO DISGUSTED!!! *TR

HUNDREDS OF COMPLAINTS ABOUT THE TRANSMISSION PROBLEMS I AM COMPLEXED THAT THERE IS NO RECALL AT THIS TIME. FEBRUARY 2012 MY GMC LOST POWER AS I WAS DRIVING. THE CAR WAS TOWED TO GMC AND I WAS TOLD SOMETHING WAS WRONG WITH THE TRANSMISSION (ON TOP OF ALL THE OTHER MAJOR PROBLEMS I HAVE HAD) THIS LUCKILY WAS COVERED UNDER THE WARRANTY. FAST FORWARD ONE YEAR LATER FEBRUARY 2013 TRANSMISSION FLUID LEAKING WENT TO THE DEALER WHERE THEY PUT IN A DYE TO TRACE THE LEAKS AS THEY SAID THEY DID NOT BELIEVE IT WAS THE TRANSMISSION, THEY WANTED TO CHARGE FOR THIS BUT AGREED TO DO THIS FOR FREE. I WAS ALSO TOLD THE TRANSMISSION THAT THEY FIXED WAS ONLY COVERED FOR 12 MONTHS OR 12,000 MILES. AT THIS POINT IT WAS A LOST CAUSE DEALING WITH THE DEALER AS THEY WERE NOT COVERING ANY OF THEIR WORK AND...

I WAS DRIVING DURING DAYLIGHT HOURS ON THE HIGHWAY AND I PRESSED ON THE GAS TO ACCELERATE BECAUSE THERE WAS A SLIGHT INCLINE ON THE ROUTE I WAS TRAVELING. WHEN I PRESSED ON THE GAS PEDAL, THERE WAS NO ACCELERATION AND I GOT NERVOUS THAT IT MIGHT BE THE ALTERNATOR. HOWEVER, I WAS STILL ABLE TO DRIVE THE VEHICLE ALTHOUGH IT DID NOT WANT TO PICK UP SPEED. I EXITED THE HIGHWAY AND NOTICED THAT THE VEHICLE WAS HAVING DIFFICULTY SHIFTING GEARS AND WAS MAKING WHAT SOUNDED LIKE A WHIRRING NOISE FROM UNDER THE HOOD. I DROVE THE VEHICLE STRAIGHT TO MY MECHANIC'S SHOP. HE WAS SURPRISED TO FIND OUT THAT IT WAS THE TRANSMISSION AS THE VEHICLE IS ROUTINELY SERVICED. IT APPEARS THAT THE WAVE PLATE FAILED AND THERE WAS DEBRIS INSIDE THE TRANSMISSION. *TR

WE BOUGHT VEHICLE FROM HENDRICK TOYOTA ON 6/15/2013. MY WIFE BEGAN DRIVING TO WORK WHEN IT COMPLETELY STOPPED IN THE MIDDLE OF THE ROAD. SHE WAS FRANTIC BECAUSE OF THE BUSY STREET AND THANKFULLY, OUR KIDS WERE NOT IN THE VEHICLE. CAR WAS TOWED TO HENDRICK WHERE IT WAS DETERMINED THAT TRANSMISSION FAILED. IT WAS TOLD TO ME THAT THE WAVE PLATE IN THESE VEHICLES WAS KNOWN TO FAIL AND AFTER RESEARCH AND A TECHNICIANS AFFIRMATION, APPARENTLY GMC NEVER TEMPERED THIS PARTICULAR PART AND HAVE KNOWN ABOUT THE ISSUE FOR QUITE SOME TIME. AGAIN, AFTER RESEARCHING, I'VE SEEN COUNTLESS COMPLAINTS/ISSUES OF PEOPLE WITH THE SAME THING HAPPENING AND THAT GM AND THEIR SERVICE AND CUSTOMER SATISFACTION DEPARTMENTS QUITE SIMPLY EXPLAIN IT AWAY AS "WELL, THERE'S NOTHING WE CAN DO" DESPITE, WHAT APPEARS TO BE, CLEAR EVIDENCE THAT THIS MAJOR POWER TRAIN PROBLEM HAS BEEN COMPLETELY IGNORED. NOW, I'M LOOKING AT...

TRANSMISSION FAILURE - WAVE PLATE BROKEN FORCING VEHICLE TO BE STUCK IN ONE GEAR AND FAIL IN REVERSE, 3RD AND 4TH GEARS. AUTOMATIC TRANSMISSION SLIPS IN REVERSE, 3RD AND 4TH. MULTIPLE OWNERS REPORT SAME ISSUES AND RECALL IS NEEDED BY GM ON THE ACADIA TRANSMISSION. *TR

MY ACADIA (WHICH I JUST BOUGHT IN MARCH) BEGAN SHIFTING HARSHLY BETWEEN THE 3RD AND 5TH GEARS AND MY CHECK ENGINE LIGHT CAME ON. THE NEXT DAY I TOOK IT TO AN AUTO REPAIR SHOP WHERE I HAD THE CODES READ AND WAS TOLD I HAD A PROBLEM WITH THE 35R WAVEPLATE AND THE TRANSMISSION CONTROL MODULE. I WAS TOLD I WOULD HAVE TO PAY $600 JUST TO HAVE MY TRANSMISSION TAKEN APART TO DIAGNOSE THE EXTENT OF THE DAMAGE. I WAS TOLD THAT A DRUM CAME APART CAUSING "EXTENSIVE DAMAGE" AND THAT I WOULD EITHER NEED A COMPLETE TRANSMISSION REBUILD FOR $3600 OR A BRAND NEW TRANSMISSION FOR $4000. THIS CAR HAS LESS THAN 100,000 MILES ON IT (ALTHOUGH I KNOW THAT IS HIGH FOR THE YEAR, A BRAND NEW TRANSMISSION FOR A FAIRLY NEW CAR IS EXTREME). I WAS TOLD BY THE MECHANIC THAT THIS IS EXTREMELY COMMON...

MY WIFE WAS DRIVING HER 2008 GMC ACADIA ON THE FREEWAY WHEN THE TRANSMISSION SUDDENLY GAVE OUT AND SLIPPED OUT OF GEAR. THE VEHICLE WOULD NOT ACCELERATE. SHE WAS IN THE FAST LANE TRAVELING 70 MPH IN THE FAST LANE. SHE HAD TO FIGHT THROUGH TRAFFIC TO GET OVER TO THE SHOULDER SO SHE COULD PULL OFF THE FREEWAY ENOUGH TO AVOID GETTING HIT BY OTHER CARS TRAVELING THE FREEWAY. SHE THEN HAD TO EXIT THE VEHICLE WITH OUR CHILDREN DURING HIGH TRAFFIC TIME. VERY UNSAFE SITUATION FOR A VEHICLE WITH ONLY 69K MILES ON IT. THIS IS A KNOWN ISSUE WITH THE 2007 AND 2008 LAMBDA PLATFORM VEHICLES. GMC KNOWS ABOUT THE 3-5-R WAVE PLATE THAT WAS NOT HEAT TREATED DURING THE BUILDING OF THESE TRANSMISSIONS. SEARCH THE WEB OR EVEN FORUMS FOR 3-5-R WAVE PLATE FAILURE AND SEE WHAT COMES UP. I FEEL THEY SHOULD ATLEAST EXTEND THE...

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 20 MPH, THE TRANSMISSION FAILED WITH THE ILLUMINATION OF THE TRANSMISSION WARNING INDICATOR. THE VEHICLE WAS TOWED TO AN AUTHORIZED DEALER FOR DIAGNOSIS WHERE THE CONTACT WAS INFORMED THAT THE TRANSMISSION CLUTCH PLATE WOULD NEED TO BE REPLACED. THE VEHICLE WAS REPAIRED HOWEVER, THE FAILURE RECURRED THREE MONTHS LATER. THE VEHICLE WAS TAKEN TO A SECOND DEALER, WHERE THE CONTACT WAS AWAITING THE REBUILDING OF THE TRANSMISSION. THE MANUFACTURER WAS NOTIFIED OF THE DEFECT. THE APPROXIMATE FAILURE MILEAGE WAS 72,000.

DRIVING GMC ACADIA TO MY SONS BASEBALL GAME AND THE CAR JERKED FORWARD, SO I IMMEDIATELY SLOWED DOWN. CONTINUED TO DRIVE AND THE CAR BASICALLY WOULD NOT GET OUT OF 1ST GEAR. THE RPM'S KEPT GOING UP AND NEVER CAME DOWN AND THE CAR WOULD NOT GO OVER 40 MPH WHILE THE ENGINE WAS GEARING UP. THE TRANSMISSION WAS COMPLETELY SHOT. TOOK TO THE DEALERSHIP TO HAVE REPAIRED. GMC HAS TONS OF 2007 AND 2008 ACADIA'S WITH THE SAME PROBLEM AND ARE FORCING CUSTOMERS TO PAY FOR THE REPAIR. THE WAVE PLATE WAS SHOT ALONG WITH EVERYTHING ELSE IN THE TRANSMISSION. ON MY BILL THEY PUT N/C IN ALL THE PARTS AND LABOR AND THEN JUST PLUGGED IN AN AMOUNT IN A LINE ITEM CALLED " MISC CUSTOMER DEDUCTIBLE" NO ONE WILL EXPLAIN THE CHARGE. DEALERSHIP TOLD ME THE GMC CALCULATES THE CHARGE AND GMC TOLD ME TO CALL THE...

I WAS DRIVING 45PMH AND ALL OF A SUDDEN I DIDN'T SEEM TO HAVE POWER SO I PULLED OVER AND CALLED MY HUSBAND WHERE HE ASKED ME MY RPM AND IF I COULD MANUALLY SHIFT, ETC. I COULD MANUALLY SHIFT AND ONLY HAD 2ND GEAR. I CALLED AND HAD IT TOWED TO THE DEALER WHERE THEY CHARGED ME $4400 TO REPLACE THE TRANSMISSION DUE TO FAULTY WAVE PLATE. NO HELP FROM GM DUE TO OUT OF WARRANTY BECAUSE I'VE HAD IT OVER 5 YEARS. *LN

2008 GMC ACADIA SLT-2 WITH 42,300 MILES; NOT YET 6 YEARS OLD. "SERVICE STABILITY CONTROL" AND "SERVICE TRACTION CONTROL" WARNINGS RECEIVED PERIODICALLY. THIS WEEK, TRANSMISSION STARTED TO SHIFT UNEVENLY; NOT CORRECTLY UPSHIFTING/DOWNSHIFTING WHILE DRIVING AT 30MPH. CAR NOW ONLY OPERATES IN 1ST GEAR. NO HIGHER GEARS, NO REVERSE.....ENGINE JUST REVS. CAR HAS COMPLETE SERVICE REC NO LONGER SAFELY DRIVABLE. APPEARS TO BE PART OF THE KNOWN WAVEPLATE ISSUE. WHY NO RECALL WITH THE GREAT NUMBER OF SIMILAR ACADIAS WITH THE SAME PROBLEM OVER AND OVER? THANKS FOR YOUR ATTENTION. *TR

WHILE DRIVING, THE VEHICLE SUDDENLY LOST POWER AND WOULD NOT ACCELERATE. THE VEHICLE COULD ONLY BE DRIVEN 20 MPH. WHEN THE VEHICLE WAS TAKEN TO THE DEALER, THE CUSTOMER SERVICE MANAGER IMMEDIATELY DIAGNOSED THE PROBLEM AND SAID HE HAD RECENLY SEEN SEVERAL GMC ACADIA'S WITH THE SAME ISSUE. HE STATED THE PROBLEM IS THE WAVE PLATE INSIDE THE TRANSMISSION WHICH ARE FAULTY IN SEVERAL GENERATIONS OF GMC ACADIAS. HE FURTHER STATED THE WAVE PLATE COULD ONLY BE REPLACE WITH ANOTHER ONE THAT IS ALSO SUCCEPTABLE TO FAILURE. UPON REPAIR OF THE PROBLEM, THE DEALER CONFIRMED THE TRANSMISSION WAVE PLATE WAS CRACKED HOWEVER SAID THERE WAS NOTHING THEY COULD DO ABOUT IT. *JS

VEHICLE HAS A DELAYED SHIFT INTO 3RD AND 5TH GEAR, WITH A VIBRATION FELT IN THOSE GEARS. FOUND CODES P0717 P0716 FOR INPUT SPEED SENSOR ON TRANSMISSION. IT IS BELIEVED THE VEHICLE HAS A BROKEN 35R WAVE PLATE AND NEED TO TARE DOWN TO INSPECT OR REPLACE TRANSMISSION AT ONLY 63,000 MILES. EXTREMELY COMMON PROBLEM ON THESE VEHICLES (PLEASE REFER TO GMC ACADIA FORUMS ONLINE EVERYWHERE FOR OTHER VICTIMS). *JS

CHECK ENGINE LIGHT CAME ON. HAD ONSTAR DIAGNOSE IT AND IT CAME BACK AS TRANSMISSION CODES. THE TRANSMISSION SOLENOID IS CLOGGED UP, COULD BE FROM CONTAMINENENTS IN THE FLUID OR COULD BE MY CLUTCH WAVE PLATE IS COMING APART LIKE SO MANY OTHERS HAVE EXPERIENCED. OUT OF WARRANTY 5 MONTHS. CONTACTED GMC CUSTOMER CARE, THEY WERE NO HELP.

WHILE ACCELERATING AT A LIGHT, THE TRANSMISSION STARTED TO JERK. WITHIN 5 MILES, COULD NOT DRIVE FASTER THAN 30 MPH. COULD NOT GET INTO REVERSE. APPEARS THAT THE TRANSMISSION IS TOTALLY SHOT. 57,000 MILES AND 5 YEARS 10 MONTHS.

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT THE STEERING WHEEL FAILED AND BECAME HARD TURN WHEN PARKING OR WHEN TURNING AT LOW SPEEDS. THE FAILURE WAS EXPERIENCED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO THE DEALER, WHO FLUSHED THE POWER STEERING LINES. THE FAILURE WAS NOT CORRECTED. THE VEHICLE WAS TAKEN BACK TO THE DEALER FOR FURTHER INSPECTION. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 77,700 AND THE CURRENT MILEAGE WAS 104,000. UPDATED 11/19/13*LJ THE CONSUMER STATED THAT THE WAVE PLATE AND TIMING CHAIN WERE BOTH REPLACED UNDER WARRANTY. THE STEERING GEAR BOX PUMP WAS NOT COVERED UNDER WARRANTY. UPDATED 12/2/2013 *JS

THE TRANSMISSION FAILED CLIMBING A HILL WITH AN APPROXIMATE 10% INCLINE. MY WIFE WAS TRANSPORTING TWO YOUNG CHILDREN AT THE TIME AT HAD TO TURN HAZARDS ON WHILE THE VEHICLE CREPT UP A VERY HEAVILY TRAVELED ROADWAY (US HIGHWAY 31). THIS OCCURRED AFTER THE TRANSMISSION WAS REPAIRED TWO WEEKS EARLIER FOR THE SAME PROBLEM. AT THAT TIME, I WAS INFORMED BY GMC THAT IT WAS THE INPUT SPEED SENSOR. TURNS OUT IT IS TRANSMISSION FAILURE, WHICH I HAVE SINCE LEARNED IS VERY COMMON WITH THIS MODEL. AFTER READING VAST ENTRIES OF MANY OTHER ACADIA USERS WITH THE SAME PROBLEM, I CAN'T HELP BUT THINK THAT THIS IS A DESIGN FLAW. I MEAN, HOW MANY TRANSMISSIONS FAIL AT 48,000 MILES. I'M JUST GLAD MY WIFE WASN'T DRIVING AT NIGHT, ON A LONG TRIP, OR ON THE INTERSTATE, WHICH WOULD HAVE LEFT MY CHILDREN AND HER IN A VERY VULNERABLE POSITION. FOR...

I'VE HAD MY GMC ACADIA IN FOR SERVICE ON THE TRANSMISSION 3 TIMES IN THE LAST 6 MONTHS: SPEED SENSOR, WAVE PLATE, NOW TORQUE CONVERTER. DEALERSHIP RESPONDS THEY ARE COMPLETELY INDEPENDENT, AND THAT THIS IS NOT AN ISSUE WITH THIS MODEL. HOWEVER, THE FAILURE OF THE TRANSMISSION IN THESE VEHICLES IS PROMINENT ON GMC ACADIA FORUMS. WHY HAS GM NOT STEPPED UP TO OWN AND FIX THIS COMMON ISSUE?

I WAS DRIVING AND IT JUST STOPPED SHIFTING/GOING ANYWHERE. THE ENGINE LIGHT CAME ON. THEN IT STARTED GOING AGAIN AND THEN STOPPED AGAIN. I TOOK IT TO THE SHOP, AND I WAS TOLD IT NEEDED A TOTAL TRANSMISSION OVERHAUL/REBUILD. A TRANSMISSION SHOULD LAST LONGER THAN 80,000 MILES. WE PAID GOOD MONEY FOR THIS VEHICLE AND I WOULD EXPECT BETTER PERFORMANCE. GM NEEDS TO STAND BEHIND THEIR VEHICLES.

TRAMISSION IS RUNNING HOT (SENDS MESSAGE TO IDLE ENGINE) THEN CHECK ENGINE LIGHT COMES ON AND TEMP FLUCTUATES UP AND DOWN. THEN CAR WILL NOT SHIFT INTO GEAR IT'S LIKE IT'S IN NEUTRAL. ABOUT 50 MILES LATER IT STARTS ALL OVER. *JS

WHILE DRIVING ON THE HIGHWAY, GOING 60 MPH, MY CAR LURCHED FORWARD AND MADE AN AWFUL SOUND. THE CAR COMPLETELY SLIPPED OUT OF GEAR INTO NEUTRAL. THE GAS WOULD NOT WORK. AFTER COASTING DOWN A HILL WE WERE ABLE TO PULL OVER.THANK GOODNESS NO ONE WAS BEHIND US. WE TURNED OFF THE CAR AND WERE ABLE TO RESTART IT, BUT THE MAXIMUM SPEED WAS 40 MPH-AND THAT WAS PUSHING IT, THE RPMS WERE REVVED SO HIGH. WE HAD CALLED A TOW TRUCK.

I WAS DRIVING ON THE INTERSTATE AND IT JUST STOPPED SHIFTING/GOING ANYWHERE. THE ENGINE LIGHT CAME ON. THEN IT STARTED GOING AGAIN AND THEN STOPPED AGAIN. I DROVE HOME AND TOOK IT TO THE SHOP LATER THAT WEEK. IT NEEDED A TOTAL TRANSMISSION OVERHAUL. A TRANSMISSION SHOULD LAST LONGER THAN 72,000 MILES. WE PAID GOOD MONEY FOR THIS VEHICLE AND I WOULD EXPECT BETTER PERFORMANCE. GM NEEDS TO STAND BEHIND THEIR VEHICLES. I DON'T EXPECT A FULL REFUND FOR MY BILL, BUT I DO EXPECT SOME SUBSTANTIAL ASSISTANCE. *TT

I BOUGHT THE 2008 ACADIA NEW IN JUNE 2008. IT JUST CAME OFF THE 5 YEAR 100,000 MILE POWERTRAIN WARRANTY (81K MILES) AND THE TRANSMISSION BEGAN TO SLIP. I HAVE READ NUMEROUS CASES WHERE THE DEFECTIVE PART IS THE WAVE PLATE. IT APPEARS COMMON IN 2007 AND 2008 ACADIA, BUICK ENCLAVE AND SATURN OUTLOOK. GM RECTIFIED THE PROBLEM BY USING NEW PARTS IN 2009 AND NEWER MODELS. GM SHOULD BE FORCED TO ISSUE A RECALL. IN THIS DAY AND AGE TRANSMISSIONS SHOULD NOT HAVE PROBLEMS AT THE LOW MILEAGE THAT HAS BEEN IDENTIFIED IN COUNTLESS NHTSA COMPLAINTS AND SOCIAL MEDIA FORUMS. *TR

I HAVE HAD PROBLEMS WITH THIS CAR FOR THE LAST 5 YEARS. FIRST THE AIRBAG LIGHT CAME ON WHEN WE WERE GOING ON VACATION I TOOK IT TO THE DEALER AND WAS TOLD IT WAS FIXED BUT IT KEPT COMING ON AND OFF TOOK IT AGAIN AND SAME THING HAPPENED IT KEPT DOING THAT SO I TOOK IT TO THE DEALER AND THEY SAID THEY HAD TO REROUTE THE AIRBAG HARNESS TO FIX THE PROBLEM. AGAIN IT ONLY LASTED FOR A FEW WEEKS AND IT CAME BACK ON. BY THAT TIME THE CAR WAS OVER 60,000 MILES AND IT WAS PAST THE EXTENDED WARRANTY SO I'M STUCK WITH THAT PROBLEM. THE TRANSMISSION HAD TO BE REPAIRED A FEW MONTHS AGO AND IT NEEDS TO BE REPAIRED AGAIN BUT DON'T HAVE MONEY TO FIX IT AND GMC WON'T RECALL THE 2007 AND 2008 ACADIAS KNOWING THAT THE ACADIAS OF THOSE 2...

I WAS DRIVING TO WORK AND NOTICED A SHUTTER WHILE ACCELERATING AND TOOK IT TO DEALERSHIP. THE TRANSMISSION FAILED AND THE DEALER SAID IT WAS A WAVE PLATE FAILURE. *TR

MY TRANSMISSION STARTED TO FAIL WHILE DRIVING AT A HIGH RATE OF SPEED ON THE HIGHWAY. THE VEHICLE WAS GETTING STUCK BETWEEN GEARS AS I WAS TRAVELING UP HILLS. TRANSMISSION FAILURE IS A VERY COMMON ISSUE WITH EARLY ACADIA'S (WITH LOW MILEAGE) AND A RECALL NEEDS TO BE ISSUED. I HAVE TAKEN IT TO THE DEALER WHO RECOMMENDS A COMPLETE TRANSMISSION REBUILD OR REPLACEMENT. *TR

TRANSMISSION WENT OUT WITHOUT ANY WARNING. I HAD MY 3 KIDS IN THE CAR WHILE GOING UP A STEEP HILL AMONGST OTHER TRAFFIC. *TR

TRANSMISSION FAILED WITH DEFECTIVE SWASH PLATES. STUCK IN GEAR AND WOULD NOT GO INTO TO REVERSE. COMMON ISSUE WITH 2008 ACADIA AND NEEDS TO BE RECALLED. LUCKILY TRANSMISSION DID NOT STICK IN GEAR ON FREEWAY THAT COULD HAVE CAUSED AN ACCIDENT. *TR

VEHICLE EXPERIENCING BAD TRANSMISSION PROBLEMS WHEN SHIFTING BETWEEN 3RD AND 5TH GEARS. AS ACCELERATING, THE VEHICLE BEGINS TO SHIFT, BUT BEGINS TO IDLE AND RPM'S RISE EXTREMELY HIGH. VEHICLE BEGINS TO SLOW DOWN AND FINALLY JERKS INTO THE NEXT GEAR CAUSING RAPID ACCELERATION. THIS ISSUE ALMOST CAUSED ME TO RUN INTO A CAR IN FRONT OF ME AFTER PULLING OFF FROM A STOPLIGHT. IT IS EXTREMELY SCARY TO CONTINUE TO DRIVE THE CAR, BUT WITH THIS BEING MY ONLY VEHICLE AND I MUST WORK, I AM FORCED TO DRIVE DAILY. WARRANTY JUST EXPIRED 5 MONTHS AGO IN MARCH AND I CANNOT AFFORD TO FIX THE PROBLEM (MARCH 24, 2013, 5 YEAR/100,000 MI. POWERTRAIN). VEHICLE WAS PURCHASED MARCH 24, 2008. *TR

TRANSMISSION FAILURE, NO REVERSE ONLY LOW RANGE, NO WARNINGS UNTIL FAILURE. *TR
