2008 GMC ACADIA Power Train Problems

TRAVELING ON THE INTERSTATE WITH MY 3 YEAR OLD DAUGHTER WHEN TRANSMISSION FAILURE MESSAGE CAME ON. HAS COME ON MULTIPLE TIMES, REQUIRING ME TO PULL ONTO THE SHOULDER OF THE BUSY ROAD WITH SEMIS SPEEDING PAST. GMC IS AWARE OF THIS ISSUE, YET REFUSES TO ADDRESS IT ON A LARGE-SCALE. SOMEONE IS GOING TO GET KILLED BEFORE THEY ACTUALLY COME TO ACTION ON THIS MANUFACTURING DEFECT!!! *TR

ENGINE WAS REVVING UP TO 4000 RPM WHILE GOING 20 MILES AN HOUR. TRANSMISSION WAS NOT SHIFTING. HAD WHOLE FAMILY IN CAR ON MAIN ROAD. VERY SCARY. SECOND TIME THIS HAS HAPPENED, LAST TIME AT 46,000 MILES REVERSE CLUTCH PLATE WAS REPLACED THAT TIME. THIS TIME ENTIRE TRANSMISSION WAS REBUILT. *TR

I WAS DRIVING TO VISIT MY DAUGHTER UP AT COLLEGE AND DRIVE HER AND 2 FRIENDS HOME. AS I DROVE THOUGH THE COLLEGE TOWN MY CAR STARTED ACTING FUNNY. JUST NOT ACCELERATING AND THE RPM WERE RACING, TRANSMISSION APPEARED TO STUCK IN FIRST GEAR. DROVE AS LITTLE AS POSSIBLE JUST NEEDED TO GET HOME SAFE. AS I WAS DRIVING HOME, AGAIN CAR NOT ACCELERATING PROPERLY. I DROVE THOUGH THE EZPASS TOLL ON THE TAPPAN ZEE BRIDGE AND MY CAR JUST WOULDN'T GO. DROVE ALONG IT WAS VERY SCARY. I HAD TO STOP ON THE SIDE OF THE ROAD IN THE BRONX. EVENTUALLY GOT IT TO THE DEALERSHIP WHO REPLACED THE REVERSE CLUTCH PLATE. *TR

3.5.R WAVED CLUTCH PLATE FAILURE IN 2008 GMC ACADIA 6 SPEED TRANSMISSION. ENGINE IN REDUCED POWER MODE. CALL TO ONSTAR - DIAGNOSTICS - TRANSMISSION ISSUES. NO REVERSE GEAR. LIMITED FORWARD GEARS. *TR

8/26/2011 - 71,309 MILES - WATER PUMP WENT OUT AND HAD TO BE REPLACED. 5/07/2012 - 86,885 MILES - TRANSMISSION SHUTTERED WHEN COMING TO A STOP IN TRAFFIC. WOULD NOT START AND HAD TO BE TOWED TO MECHANIC. TRANSMISSION ASSEMBLY REPLACED WITH GM REMAN TRANSMISSION DUE TO BROKEN REVERSE WAVE PLATE THAT DAMAGED THE CARRIER, SUN SHELL AND METAL THROUGHOUT. ALSO DETECTED AN OIL LEAK IN THE ENGINE FRONT COVER THAT NEEDED TO BE REPAIRED AND HEARD POWER STEERING NOISE SO BLED POWER STEERING SYSTEM. 12/31/2012- 100,947 MILES - HEADLIGHT SWITCH FELL INSIDE DASH PANEL. 7/26/2013 - 112,506 MILES - POWER STEERING HAS NEVER WORKED PROPERLY. IT HAS ALWAYS MADE NOISES AND HAS BEEN STIFF. HAD IT BLED SEVERAL TIMES WITH NO IMPROVEMENT. POWER STEERING WENT OUT WHILE MAKING A LEFT HAND TURN INTO A BUSY INTERSECTION. AT SHOP NOW TO DETERMINE IF IT NEEDS A NEW POWER STEERING PUMP,...

WE LIVE IN CAMARILLO CA. WE LEFT TO GO TO SACRAMENTO FOR MY DAUGHTERS COLLEGE ORIENTATION. ABOUT TWO HOURS INTO THE FIRST LEG OF OUR TRIP THE DIC INFORMED US THE TRANSMISSION WAS OVERHEATING AND THE CAR SHOULD BE IDLED FOR IT TO COOL OFF. WE DID JUST THAT. AFTER IT COOLED OFF WE BEGAN DRIVING AGAIN. IT DID THIS ONCE MORE BEFORE WE ARRIVED IN SAN LUIS OBISPO. WE LEFT THE NEXT DAY TO SACRAMENTO. AGAIN ABOUT TWO HOURS INTO THE DRIVE THE SAME THING OCCURRED. WE IDLED THE CAR, TRANS COOLED OFF AND WE GOT UNDER WAY AGAIN. IT DID THIS ONCE MORE BEFORE WE ARRIVED IN SACRAMENTO.. WHILE IN SACRAMENTO IT DROVE FINE. ON OUR RETURN TRIP IT DID THIS TWICE ON THE WAY HOME. AFTER LOOKING BACK IT SEEMED TO DO THIS WHEN WE WERE GOING UP AN INCLINE. WE WERE NOT TOWING ANYTHING EITHER. WE...

AT DRIVING SPEED IT WAS NOTICED THAT ACADIA BEGAN TO FAIL TO SHIFT GEARS, BASICALLY ON HIGHWAY IT IS STUCK IN FIRST GEAR AND AFTER FINDING A PLACE TO STOP, IT WILL NOW NOT GO INTO REVERSE. HAVE FOUND THE EDMUNDS, ASK AND NUMEROUS OTHER SITES ARE FULL OF TRANSMISSION COMPLAINTS CONCERNING THE 2008 ACADIA AND IT'S FAILURES. THIS TRANSMISSION HAS HAD MINOR ISSUES IN PAST, MINOR LEAK AND SOME WHINING, BUT THIS IS A COMPLETE AND HAZARDOUS FAILURE WHILE DRIVING IN TRAFFIC. I HAVE SINCE LEARNED THAT THIS IS A COMMON AND KNOWN ISSUE TO GENERAL MOTORS COSTING THE CONSUMERS APPROX. $3000 TO $3500 PER INSTANCE. IS THERE NOTHING TO BE DONE TO ASSIST THE CONSUMERS? *TR

I WAS DRIVING MY ACADIA TO WORK ON MONDAY MORNING AND IT STARTED HAVING TRANSMISSION PROBLEMS, IT WOULD NOT SHIFT IN THE LOWER GEARS AND WOULD REV UP TO 4-5 RPM BETWEEN GEARS. I DROVE IT TO A TRANSMISSION SHOP THE NEXT MORNING AND THEY DIAGNOSED IT, NEEDED A WHOLE NEW TRANSMISSION. UPON LEAVING THE TRANSMISSION SHOP, IT COMPLETELY STOP MOVING, CAUSING ME TO ROLL TO A COMPLETE STOP ON A HIGHWAY. I GOT IT PULLED OVER, STOPPED THE VEHICLE AND RESTARTED IT. I WAS ABLE TO DRIVE A BLOCK OR SO BEFORE IT STOPPED AGAIN. I WAS STRANDED AND STUCK IN THE MIDDLE OF THE ROAD. I WAS FINALLY ABLE TO GET IT TO A PARKING LOT AND HAD IT TOWED TO A DEALER TO LOOK AT. *TR

I WAS AT MY SON'S BASEBALL GAME AND WENT TO MOVE MY VEHICLE WHEN I WAS PULLING OUT OF THE PARKING LOT AND THE VEHICLE STARTED REVVING AND WOULD NOT MOVE OTHER THAN COASTING (SINCE I WAS ON A HILL). I WAS 3 HOURS FROM HOME AND HAD TO HAVE THE VEHICLE TOWED TO THE TUNE OF $300.00 +. I HAVE SINCE HAD TO HAVE THE TRANSMISSION REPLACED. THIS HAS COST OVER $4500.00 NOT TO MENTION HAVING TO DRIVE 2 VEHICLES WITH MY FAMILY SINCE THE ACADIA WAS THE LARGER OF OUR VEHICLES. *TR

ABOUT A WEEK AGO MY FAMILY AND I WERE DRIVING HOME FROM VACATION AND HAD BEEN ON THE ROAD FOR ABOUT 3.5 HOURS. AS WE PULLED OUT OF A DRIVEWAY ABOUT 5 MINUTES FROM OUR HOME THE CAR ENGINE LIGHT CAME ONE, THE CAR WOULD NOT GAIN SPEED LIKE NORMAL AND IT BEGAN TO OVER HEAT RAPIDLY. WE TOOK SIDE ROADS AND SLOWLY CRAWLED HOME. I TOOK IT INTO THE SHOP THE NEXT DAY AND IT CAME BACK WITH A CRACK IN THE RADIATOR AND CODES P0700 AND P07016, WHICH THEY CONFIRMED TO BE A TRANSMISSION ISSUE AND SUGGESTED TO HAVE A SPECIALIST LOOK AT IT. I DID SOME RESEARCH AND FOUND THAT THIS ARE COMMON CODES THAT COME BACK FOR THE 2007 AND 2008 ACADIA'S THAT REQUIRE A REBUILD/REPLACED TRANSMISSION WITH AN AVERAGE COST OF $4000. THIS IS A KNOWN ISSUE WITH GMC FOR MANY YEARS AND THEY HAVE...

WE ARE A FAMILY OF 5 DRIVING ALONG THE HIGHWAY WHEN THE CHECK ENGINE LIGHT CAME ON. WE STOPPED AND PUT THE CAR INTO PARK. WHEN I WENT TO PUT INTO DRIVE, THE CAR WOULD NOT ENGAGE. FINALLY AFTER A FEW MINUTES WE WERE ABLE TO GET THE CAR GOING AGAIN, BUT THE CAR WOULD NOT SHIFT ITSELF (AUTOMATIC TRANSMISSION). WE THEN HAD TO DRIVE ALONG THE SIDE OF THE HIGHWAY FOR 13 MILES TO THE NEXT TOWN WITH THE HAZARDS ON AT 20 MILES PER HOUR. WENT TO A CHEVY DEALERSHIP AND AFTER THEY READ THE CODES, THERE APPEARS THAT THE TRANSMISSION IS COMPLETELY OUT. WE WERE MORE THAN 800 MILES AWAY FROM HOME ON VACATION IN MISSOURI. THE CAR IS STILL IN MISSOURI AT THE DEALERSHIP, AS THEY WILL NOT BE ABLE TO TAKE THE TRANSMISSION APART UNTIL EARLY NEXT WEEK. *TR

AS I WAS PULLING OFF OF THE INTERSTATE ONTO ROCKVILLE RD I NOTICED THAT THE CAR UPSHIFTED FROM 3RD VERY VIOLENTLY. I THEN HIT A STOP LIGHT AND IT DOWSHIFTED PRETTY ROUGH AS WELL. I THOUGHT UH OH AND NOTICED THE CHECK ENGINE LIGHT COME ON. WHEN I PULLED AWAY FROM THE LIGHT I NOTICED THE CAR WAS MOST LIKELY STUCK IN 3RD GEAR AS THE RPMS MATCHED THE MPH AND FROM DRIVING A STICK ALL THOSE YEARS THEY MADE SENSE. I LATER FOUND OUT THIS WAS DONE ON PURPOSE TO STICK THE TRANSMISSION IN 3RD GEAR TO FURTHER DAMAGE IT AND ALLOW YOU TO CONTINUE TO DRIVE. I GOT TO WORK AND HAD ONSTAR RUN A DIAGNOSTIC. IT CAME BACK WITH A P2715 CODE FOR THE TRANSMISSION CONTROL. AFTER LOOKING INTO THIS CODE IT APPEARS TO INVOLVE THE 3-5-R WAVEPLATE THAT CONTROLS THE CLUTCH FOR THESE GEARS. I, OF...

WHILE IN TRAFFIC, MY ENGINE REVVED UP AND MY VEHICLE JOLTED FORWARD WHEN MY TRANSMISSION STOPPED WORKING. IF ANYONE WOULD HAVE BEEN BEHIND ME, THERE WOULD HAVE BEEN A MAJOR ACCIDENT. *TR

WHILE MY WIFE WAS DRIVING OUR 5 CHILDREN ON THE HIGHWAY THE TRUCK STOPPED ON HER. SHE WAS ABLE TO RESTART IT BUT ONLY DRIVE ABOUT 40MPH WHILE THE RPM'S WERE REDLINING. THE REVERSE WENT COMPLETELY OUT. SHE ENDED UP HAVING TO PUSH THE TRUCK BY HERSELF WITH ALL THE KIDS INSIDE. THE DEALERSHIP SAYS THE TRANSMISSION IS BAD, IT'LL COST $2600 TO REPAIR. FROM READING THE FORUMS IT'S OBVIOUS THERE IS A PROBLEM WITH THE TRANSMISSION WITH THIS PARTICULAR TRUCK. WE ARE VERY FORTUNATE NO ONE WAS INJURED. *TR

MY TRANSMISSION FAILED ON MY GMC ACADIA AT JUST UNDER 62000 MILES. AS I UNDERSTAND THIS IS A VERY COMMON OCCURRENCE WITH THE MODEL YEAR AND COULD EASILY CAUSE A MAJOR ACCIDENT. WHEN MINE FAILED, I LOST ALL POWER TO THE WHEELS. HAD I BEEN IN HEAVY TRAFFIC, IT MOST CERTAINLY COULD HAVE CAUSED AN ACCIDENT. GM NEEDS TO RECALL THESE VEHICLES. *TR

TRANSMISSION FAILURE IMMEDIATELY FOLLOWED BY ENGINE FAILURE AFTER THE TRANSMISSION WAS REPLACED. *TR

ON OCCASION, OUR 2008 ACADIA WOULD NOT SHIFT OUT OF LOW GEAR WHEN FIRST ATTEMPTING TO DRIVE. THE TAC WOULD REV TO 5-6000 RPM AT A MAX OF ABOUT 20 MPH. WE WOULD NEED TO PULL OVER, TURN OFF THE VEHICLE, WAIT A FEW MINUTES AND RESTART. AT THIS POINT EVERYTHING WOULD BE FINE WITH THE EXCEPTION OF THE CHECK ENGINE LIGHT BEING DISPLAYED. AT FIRST THIS WOULD HAPPEN VERY RARELY. IT THEN BEGAN TO HAPPEN MORE FREQUENTLY. THE LAST INCIDENT WAS VERY SCARY FOR MY SON, A NEW DRIVE. HE ATTEMPTED TO PULL OUT INTO HEAVY TRAFFIC ON A STREET WITH A 50 MPH SPEED LIMIT. THE VEHICLE WOULD ONLY GO 20 MPH AND THERE WAS NO SHOULDER FOR HIM TO PULL OVER. WE TOOK IT TO THE DEALER AND THEY DIAGNOSED THE PROBLEM AS A FAILED WAVE PLATE. AND FROM WHAT I HAVE BEEN READING, A VERY COMMON...

I RECENTLY PURCHASED A 2008 GMC ACADIA IN APRIL OF THIS YEAR. ON JUNE 16TH MY HUSBAND AND I DID NOT GET ANY TYPE OF WARNING BEFORE OUR VEHICLE COMPLETELY STOPPED BECAUSE THE ENGINE LIGHT DID NOT COME ON UNTIL AFTER IT MADE A LOUD SOUND RIGHT BEFORE QUITTING. IT WAS A GOOD THING THAT MY FAMILY AND I WERE ON A BACK ROAD WHEN THIS HAPPENED OR THERE WOULD HAVE BEEN SOME FATALITIES. THE VEHICLE WOULD START AFTERWARDS BUT WOULD NOT PULL IN ANY GEAR. WE CONTACTED A MECHANIC AND HE INFORMED US THAT HE HAD WORKED ON PLENTY OF ACADIA'S WITH THE EXACT SAME PROBLEMS AND WHEN HE CHECKED OUR VEHICLE IT WAS NO EXCEPTION. OUR REVERSE FUNCTION WAS COMPLETELY GONE OUT IN THE COMPUTER SYSTEM AND THE TRANSMISSION HAD TO BE REBUILT. I CALLED THE DEALERSHIP TO SEE WHAT THEY COULD DO SINCE THEY TOLD ME THAT...

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING 20 MPH, THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSIS AND THE CONTACT WAS INFORMED THAT THE THIRD AND FIFTH GEARS IN THE TRANSMISSION HAD FAILED AND THE TRANSMISSION WOULD NEED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 50,000.

IN FEBRUARY OF THIS YEAR (2013) THE TRANSMISSION IN OUR 2008 GMC ACADIA FAILED WHILE I WAS DRIVING MY TWO SMALL CHILDREN HOME FROM PRESCHOOL. THANKFULLY I NEVER LOST CONTROL OF THE CAR ALTHOUGH IT WAS EXTREMELY FRIGHTENING AND A VERY DANGEROUS EXPERIENCE TO NOT BE ABLE TO SHIFT INTO ANOTHER GEAR WHILE IN THE MIDDLE OF MOVING TRAFFIC ON A BUSY ROAD. I BARELY MADE IT HOME, DROVE WITH MY HAZARD LIGHTS ON, SHAKING AND COUNTING MY BLESSINGS THAT OUR CAR WAS NOT HIT AND WE WERE NOT HURT. WHAT MAKES IT ALL THE MORE UPSETTING IS THAT GM IS AWARE OF THIS ISSUE WITH 2008 ACADIA MODELS BUT YET HAS NEVER DONE A RECALL ON THE DEFECTIVE TRANSMISSIONS IN OUR CARS. GM IS ESSENTIALLY TELLING IT'S CUSTOMERS THAT IT DOES NOT CARE ABOUT THEIR SAFETY OR WELL BEING. THEY ALLOW US TO CONTINUE TO DRIVE THEIR CARS EVEN...

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT SHE ATTEMPTED TO SHIFT GEARS BUT THE VEHICLE DID NOT RESPOND. THE VEHICLE WAS TAKEN TO A PRIVATE MECHANIC, WHO STATED THAT THE FAILURE WAS CAUSED BY A FAULTY WAVE PLATE IN THE TRANSMISSION. THE VEHICLE WAS NOT REPAIRED. THE FAILURE WAS NOT REPORTED TO THE MANUFACTURER. THE FAILURE AND CURRENT MILEAGE WAS 62,000.

I OWN A GMC ACADIA 2008 THAT STARTED HAVING TRANSMISSION PROBLEMS ONE YEAR AGO (JULY 2012), I WAS ON A BUSY HIGHWAY IN AUSTIN, TX AND HAD MY THREE YOUNG DAUGHTERS WITH ME WHEN I STARTED NOTICING I COULDN'T ACCELERATE VERY WELL. NEXT DAY MY GMC ACADIA JUST STOPPED IN THE MIDDLE OF A ROAD AND I COULDN'T ACCELERATE AT ALL, THANK GOD THIS TIME MY DAUGHTERS WERE NOT IN THE CAR WITH ME. I HAD THE CAR TOWED AND IT TURNED OUT THE PROBLEM WAS A BROKEN WAVE PLATE WHICH SEEMS TO BE A VERY COMMON PROBLEM WITH GMC ACADIAS 2007 AND 2008. *TR

TRANSMISSION ON 2008 GMC ACADIA STOPPED WORKING. TOWED TO LEHMER'S GMC IN CONCORD, CA. ADVISED THAT TRANSMISSION MUST BE REBUILT OR REPLACED. *TR

ON A TRIP FROM TEXAS TO COLORADO OUR TRANSMISSION FAILED. DRIVING ON SATURDAY - TRANSMISSION WAS ACTING FUNNY. STOPPED FOR NIGHT - GOT UP NEXT DAY TO PULL OUT OF PARKING LOT ONTO HIGHWAY AND TRANSMISSION SLIPPED OUT OF GEAR - COULDN'T GET IT BACK INTO GEAR - MANAGED TO STEER TO RIGHT HAND SIDE SHOULDER. COULD HAVE BEEN DISASTROUS IF I HAD MADE IT OUT ONTO HIGHWAY WITH CROSS-TRAFFIC COMING. LOOKING ON EDMUNDS.COM IT SEEMS THIS IS A VERY PERSISTENT ISSUE WITH GM ACADIAS & BUICK ENCLAVE GM MODELS. *TR

ON JUNE 19, 2013 I WAS DRIVING MY 2008 GMC ACADIA FROM MY HOME TO WORK. I NEEDED TO TURN RIGHT FROM MY RESIDENTIAL SIDE STREET ONTO A MAJOR FOUR LANE HIGHWAY. I HAD A RED LIGHT BUT COULD TURN RIGHT ON RED IF I YIELDED TO ONCOMING TRAFFIC. THERE WAS A CAR APPROACHING TRAVELING THE SAME DIRECTION AS I WAS TURNING BUT I KNEW I HAD SUFFICIENT TIME TO TURN AND ACCELERATE BEFORE THE CAR REACHED ME. AS I WAS TURNING RIGHT FROM MY SIDE STREET ONTO THE HIGHWAY, I PRESSED THE GAS TO ACCELERATE AND THE CAR BEGAN TO MOVE FORWARD BUT AT A VERY, VERY SLOW PACE, THE ENGINE BEGAN TO REV VERY LOUDLY, AND THE CAR WAS JERKING VERY BADLY. AT THAT POINT I WAS FULLY ON THE HIGHWAY BUT COULD NOT ACCELERATE MY CAR. LUCKILY THERE WERE NO CARS IN THE FAR LEFT LANE OF...

WE WERE DRIVING DOWN THE ROAD AND ALL OF THE SUDDEN THE CAR MADE A LOUD ROARING NOISE LIKE SOMEONE WAS MASHING THE ACCELERATOR TO THE FLOOR. THE TRANSMISSION SEEMED LIKE IT DID NOT KNOW WHAT GEAR IT WAS IN HENCE GOING FROM 50 MPH TO 30 RAPIDLY COULD HAVE CAUSED A SERIOUS ACCIDENT. HAD I BEEN THE MIDDLE OF AN INTERSECTION OR PULLING OUT INTO TRAFFIC IT COULD HAVE CAUSED A LIFE THREATENING ACCIDENT. WE CONTACTED ONSTAR AND THE CODES INDICATED TRANSMISSION PROBLEM OF A BROKEN WAVE PLATE. CODE P2715 THE ACADIA WILL NOT BACK UP AT ALL. THERE ARE NUMEROUS BLOGS OF PEOPLE HAVING THE SAME PROBLEMS WITH THE ACADIA'S WAVE PLATE RANGING IN THE YEAR OF 2007-2009. SEEMS LIKE IT IS A REALLY BAD DESIGN AND NOT STRONG ENOUGH FOR THIS TYPE OF SUV. I CAN NOT UNDERSTAND WHY GMC IS NOT RECALLING OR OFFERING TO PAY...

WE PURCHASED OUR 2008 ACADIA IN 2011, IT HAD APPROXIMATELY 30,000 MILES ON IT AT THE TIME OF PURCHASE. LESS THAN THIRTY DAYS AFTER PURCHASE WE HAD TO REPLACE THE FRONT ROTORS. AT 40,000 MILES WE HAD TO REPLACE THE FRONT BRAKES; THE AIR CONDITIONER BACKED UP, WHICH REQUIRED MAINTENANCE TO THE BLOWER MOTOR; AND THE HEAD LIGHTS WENT OUT, WHICH REQUIRED REPLACEMENT. AT 45,000 MILES THE REAR STRUTS WENT OUT, WHICH REQUIRED REPLACEMENT; AND WE HAD TO REPLACE TWO TIRES. AT 60,000 MILES THE WATER PUMP WENT OUT AND NEEDED TO BE REPLACED. AT 55,000 MILES THE FRONT STRUTS WENT OUT, WHICH NEEDED REPLACING, ALONG WITH FOUR NEW TIRES, AND A NEW SET OF HEADLIGHTS. AT 60,000 MILES THE REAR BRAKES AND ROTORS NEEDED TO BE REPLACED. AT 70,000 MILES THE TRANSMISSION WENT OUT, WHICH ALSO REQUIRED REPLACEMENT. THE FINAL INCIDENT HAPPENED ON 6/10/13 AT 74,000 MILES, WHILE I...

WHILE DRIVING ON A HIGHWAY, THE CAR WENT INTO NEUTRAL AND LOST POWER. AFTER A FEW SECONDS, IT WENT INTO LOW GEAR AND WOULD NOT SHIFT INTO A HIGHER GEAR. THE TRANSMISSION REQUIRED A RE-BUILD TWO YEARS EARLIER AT 62,000 MILES AND IS NOW FAILING AGAIN. WE WERE TOLD THE TRANSMISSION MUST BE RE-BUILT YET AGAIN. WE CANNOT DRIVE THE CAR AS THE LOSS OF POWER AND SLIPPING TRANSMISSION IS VERY DANGEROUS. THE TRANSMISSION DESIGN, AND THE SUBSEQUENT REPAIR BY THE DEALER, WAS FAULTY. AS OUR WARRANTY EXPIRED 4 MONTHS AGO, WE WERE A NEW TRANSMISSION WAS REQUIRED AT $4,000. *TR

WHILE TRAVELING DOWN THE ROAD AT HIGHWAY SPEEDS, THE VEHICLE LOOSES POWER ON ITS OWN, AND DOWN SHIFTS TO FIRST GEAR AT TIMES, WITHOUT THE ABILITY TO SHIFT INTO HIGHER GEARS. ALSO AT TIMES, YOU PULL UP TO A INTERSECTION, AND THE VEHICLE WILL NOT PULL OFF UNDER ITS OWN POWER. VEHICLE HAS 80,000 MILES ON IT, WITH A 100,000 MILE POWER TRAIN WARRANTY. GM SAYS THE WARRANTY WENT OUT IN OCTOBER OF 2012. THE VEHICLE HAS MULTIPLE HISTORY OF GM REPROGRAMMING THE TRANSMISSION, AND THE VEHICLE HAS BEEN SERVICED REGULAR. *TR

1. TRANSMISSION GOING OUT AT 67K MILES AND APPEARS TO BE VERY PREVALENT WITH THIS MAKE AND MODEL OF VEHICLE. VERY DANGEROUS AS THE CAR WILL NOT GO INTO GEAR AT ANY GIVEN TIME AND BASICALLY LEAVES YOU STUCK IN NEUTRAL IN THE MIDDLE OF A BUSY HIGHWAY. 2. SERVICE AIR BAG LIGHT STAYS ON AFTER DEALERSHIP CLAIMS TO HAVE FIXED THE PROBLEM. IF IN A CRASH, HAVE NO IDEA IF WE WILL BE PROTECTED. NOT A COMFORTABLE FEELING. *TR

WHILE DRIVING AT ABOUT 45MPH, THE VEHICLE LOST POWER TO THE WHEELS, THE ENGINE RACED AND THE TRANSMISSION APPEARED TO FAIL. THE VEHICLE WAS SHUT OFF, AND RESTARTED WITH ONLY 1ST AND 2ND GEAR AVAILABLE AND WAS MOVED TO SAFETY. THE PROBLEM OCCURRED AT APPROXIMATELY 55,000 MILES. A P0776 CODE WAS PULLED FROM THE COMPUTER AND THE GMC DEALER CHECKED THE PROBLEM AND CONCLUDED THAT THE 3,5,R WAVE PLATE IN THE TRANSMISSION FAILED AND WILL REQUIRE A FULL REBUILD. WITH THE NUMEROUS COMPLAINTS ABOUT THIS SPECIFIC PROBLEM, I'M VERY DISAPPOINTED IN GM FOR THEIR LACK OF CUSTOMER SUPPORT IN WHAT APPEARS TO BE A MANUFACTURING DEFECT IN THE 6T70 TRANSMISSIONS, AS THIS ISSUE IS OCCURRING IN 2007-2009 GMC ACADIAS, BUICK ENCLAVES, CHEVROLET TRAVERSES AND THE SATURN VUES. DO SOMETHING GM! *TR

THE CAR TRANSMISSION HAS FAILED AS SOON AS THE CAR TURNED 5 YEARS. THE CAR HAS BEEN RARELY DRIVEN. AFTER CHECKING WITH MANY GARAGES I HAVE FOUND THAT THE GMC ACADIA 2008 MODEL HAS A BEEN KNOWN FOR TRANSMISSION FAILURES BY DESIGN AND IT IS NOT AN ISOLATED CASE. THIS IS A RIP OFF. *TR

THERE WAS A "CLUNK" UPON ACCELERATION FROM STOPPED, SOON AFTER VEHICLE WOULD NOT MOVE. WAVE PLATE WAS DESTROYED IN TRANSMISSION CAUSING A NEED TO BE REBUILT, AS SO MANY, IF NOT ALL OTHERS IN 2007-2009 GMC ACADIAS HAVE BEEN. OUT OF POCKET COST TO ME IS $3,500 BECAUSE GM USED A $2 PART INSTEAD OF AN $8 PART. THIS IS AN HUGE SAFETY ISSUE THAT IS STRANDING PEOPLE, MOTHERS WITH CHILDREN, IN DANGEROUS SITUATIONS, ALL THE WHILE, GM IS WELL AWARE OF THE PROBLEM AND SOLUTION BUT REFUSES TO STEP UP AND TAKE RESPONSIBILITY FOR IT. THERE NEEDS TO BE A SAFETY RECALL FOR THIS ISSUE. *TR

TRANSMISSION BLEW. *TR

I WAS DRIVING MY 2008 GMC ACADIA ALONG WITH MY SISTER AND HER TWO GOD CHILDREN. WE WERE AT A RED LIGHT AND PROCEEDED TO GO WHEN THE LIGHT TURNED GREEN. GOT UP TO 20MPH AND THE SUV JERKED SEVERELY. ONCE IT JERKED THE SUV WOULD NOT GO OVER THAT MILEAGE. WE WERE ALL SCARED! I TOOK THEM HOME AND DROVE TO A GM DEALERSHIP. I PAID $114.00 FOR A DIAGNOSTIC TEST AND WAS TOLD THEY DID NOT KNOW WHAT WAS WRONG. THEY SPECULATED THAT A WAVE PLATE BROKE OR MOVED. THEY ADVISED IN ORDER TO KNOW FOR SURE, I WOULD HAVE TO PAY 900.00 PLUS FOR A DEEPER DIAGNOSTIC! I'M UNDER MY 100K MILEAGE AND NO ONE IS HONORING THAT. I'M A MBA STUDENT AND DON'T HAVE THAT KIND OF CASH! I'VE ONLY HAD THIS SUV FOR 3 YEARS. I BOUGHT IT USED, HAD ONLY ONE OWNER BEFORE ME,...

MY CAR ENGINE STARTING REVVING WHILE DRIVING AT NORMAL SPEEDS. WHILE DRIVING WITH MY 3 CHILDREN IN THE CAR, IT CAME TO A DEAD STOP AND COULDN'T GO IN REVERSE. THE VEHICLE WAS TOWED AND THEN DIAGNOSED WITH A BROKEN 35R CLUTCH WAVE PLATE. HAD TO HAVE THE TRANSMISSION REBUILT AT 48K MILES. THE CAR HAD BEEN DRIVEN LESS THAN 10K MILES A YEAR FOR 5.5 YEARS. *TR

WHILE DRIVING DOWN INTERSTATE STATE AT 70MPH I CAME UP ON SLOWER TRAFFIC AND HAD TO SLOW DOWN TO 60-65MPH BEFORE I COULD CHANGE LANES. ONCE CHANGING LANES AND AS I WENT TO ACCELERATE THE VEHICLE SEEMED TO DOWNSHIFT AND RPM WENT FROM 1800-2000 TO 5000 AND THE VEHICLE BASICALLY STALLED FOR ABOUT 5 SECONDS CAUSING A 18 WHEELER TO BASICALLY ALL BUT WRECK TO KEEP FROM KILLING ME AND MY OTHER 5 FAMILY MEMBERS IN THE VEHICLE. I PULLED OVER AT THE NEXT EXIT AND MADE SURE THERE WAS NO KIND OF TRANSMISSION CODES OR ANYTHING TO SHOW UP ON THE DASH BUT I STILL CHECKED MY FLUIDS AND EVERYTHING CHECKED TO OK. I HAD 325 MORE MILES TO GET HOME SO I BASICALLY HAD TO BABY IT TO THE HOUSE. IT HAPPENED SEVERAL MORE TIMES DURING THE TRIP BUT THAT WAS THE WORST. I HAVE ALSO EXPERIENCE ON...

I HAVE BEEN VERY DISAPPOINTED WITH MY VEHICLE! WHEN I WAS IN THE MARKET FOR A NEW VEHICLE I NEW I WANTED THE ACADIA. I HAVE BEEN A LONG TIME CUSTOMER AT MY LOCAL DEALERSHIP AND WHEN I ARRIVED AT THE LOT THEY HAD JUST BROUGHT IN A 2008 THAT HAD ONE OWNER. I WAS ECSTATIC BECAUSE IT WAS EVERYTHING I COULD WANT AND NOT AS EXPENSIVE AS A 2012. WHEN I FIRST STARTED DRIVING IT WAS GREAT I LOVED IT! I BOUGHT THE CAR WITH 8,000 OR SO MILES ON IT AND AS TIME WENT ON I STARTED TO NOTICE THAT IT WASN'T DRIVING LIKE IT DID THE FIRST DAY I BOUGHT IT. I DRIVE TO AND FROM WORK 5 DAYS WEEK ROUGHLY 35 MILES A DAY. I WAS IN TOWN AT THE BANK AND AS I STARTED TO PULL OUT INTO THE LANE MY RPM'S WENT SKY HIGH...

VEHICLE LEAKS WATER WHEN IT RAINS ONTO DRIVER AND FRONT PASSENGER. WATER LEAKS INTO AIRBAGS AND VISORS. AFTER RAINS, VEHICLE WILL NOT TURN OFF, EVEN WITH KEY REMOVED. VEHICLE ROLLS SIGNIFICANTLY WHILE IN PARK OR WHEN IN GEAR. TRANSMISSION SKIPS AND SLIPS. *TR

I PURCHASED A 2008 GMC ACADIA ONE YEAR AGO. IT SEEMED LIKE WE HAD MADE A GOD SENT DEAL AND NOW WE ARE FINDING OUT THAT THE TRANSMISSION IS GOING OUT. OUR FAMILY DOESN'T HAVE A WHOLE LOT OF MONEY TO JUST THROW AWAY AND WE PUT DOWN $5000 AND NOW WE ARE LOOKING DOWN THE BARREL OF A TRANSMISSION. NOT FAIR CONSIDERING THE DEALERSHIP APPARENTLY KNEW IT WAS ABOUT TO GO OUT. I WAS DRIVING WITH 3 OTHER TEENS IN MY CAR AND ALL OF A SUDDEN IT WOULDN'T GO FASTER THAN 25 MPH. *TR

I WAS DRIVING DOWN THE HIGHWAY ON FRIDAY AFTERNOON AT 65 MPH WHEN I TRIED TO ACCELERATE TO PASS A VEHICLE, AND THE ENGINE JUST REVVED NEARLY TO THE REDLINE. I WAS ABLE TO REACH THE EXIT, WHERE I PULLED OVER, PUT THE CAR IN PARK, THEN BACK INTO DRIVE TO START OFF AGAIN. AT THIS POINT, THE CAR WOULD NOT SHIFT OUT OF 1ST GEAR. I WAS ABLE TO MAKE IT TO A MIDAS SHOP FOR A CHECK AND THEY STATED THAT THE TRANSMISSION WAS SHOT. CALLED THE LOCAL GMC DEALER AND HAD THE CAR TOWED THERE FOR A DIAGNOSTIC. THEY CALLED SATURDAY AFTERNOON AND CONFIRMED THAT THE TRANSMISSION NEEDS TO BE REPLACED AT A COST OF $3700. THE CAR IS 24K MILES UNDER WARRANTY MILEAGE, BUT JUST HAPPENS TO BE 5 MONTHS OUTSIDE OF THE 5 YEAR WARRANTY WINDOW. I THEN CALLED GMC CUSTOMER CARE FOR REDRESS AND...

MY WIFE WAS DRIVING THE VEHICLE AND APPROACHED A STOP SIGN. ONCE SHE TRIED GOING AGAIN THE CAR WOULD NOT ACCELERATE AND WE HAD TO TOW IT TO THE DEALER. THEY SAID THE TRANSMISSION WENT OUT @ 68,000 MILES? ALSO THE WATERPUMP, POWERSTEERING PUMP. MASTER CYLINDER, AS WELL AS SOMETHING WITH AN AIR BAG CONNECTOR. THE AIR BAG CONNECTOR HAS BEEN GOING ON AND OFF FOR THE LAST TWO YEARS SINCE WE BOUGHT IT TWO YEARS AGO AS A GM CERTIFIED PRE-OWNED VEHICLE. I AM NOT SURE HOW THIS VEHICLE HAS NOT BEEN RECALLED. *TR

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 40 MPH, THE VEHICLE SHOOK AND INDEPENDENTLY DECELERATED TO 10 MPH THEN STALLED. AFTER RESTARTING, THE TRANSMISSION FAILED TO SHIFT INTO REVERSE. THE VEHICLE WAS ABLE TO RESUME NORMAL OPERATION. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER FOR DIAGNOSIS. THE TECHNICIAN STATED THAT THE TRANSMISSION WAVE PLATE FRACTURED WHICH CAUSED INTERNAL DAMAGE. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE PROBLEM. THE APPROXIMATE FAILURE MILEAGE WAS 70,000.

I WAS DRIVING TO THE STORE WHEN I TURNED A CORNER AND WENT TO HIT THE GAS TO GO AND I HAD NOTHING! MY CAR STARTED ROLLING BACKWARDS DOWN THE HILL INTO TRAFFIC. I WAS LUCKY TO NOT BE HIT. I SLAMMED ON THE BRAKES AND THREW IT INTO PARK. I TURNED MY CAR OFF AND RESTARTED IT AND TRIED TO MOVE IT AND I HAD NO DRIVE SO I TRIED TO PUT IT IN REVERSE TO BACK IT UP ON THE SIDE OF THE ROAD AND NOTHING I HAD NO DRIVE NO REVERSE NOTHING!!!!! I HAD IT TOWED TO THE SHOP AND I STILL KNOW NOTHING ON WHY IT HAPPENED EXCEPT THEY SAID THERE IS AN INTERNAL TRANSMISSION ISSUE. I HAVEN'T EVEN OWNED IT A YEAR. I RELY ON THIS CAR TO SAFELY GET MY THREE KIDS WHERE THEY NEED TO BE AND NOW I'M TERRIFIED TO PUT MY...

I WAS TAKING MY DAUGHTER TO FLORIDA FOR CHEER LEADING COMPETITION; I WAS JUST OUTSIDE OF ILLINOIS WHEN THE CHECK AIRBAG LIGHT AND MESSAGE SCREEN CAME ON THANKFULLY THE LIGHT WENT OFF BUT CAME BACK ON ON OUR WAY BACK TO CHICAGO AND KEPT COMING ON AND OFF. TOOK IT TO DEALER BUT THEY ONLY SAID THAT THE HARNESS WAS TIGHT THEY ONLY WIGGLED IT AND LIGHT WENT OFF BUT CAME BACK A COUPLE OF DAYS LATER. THEN THE POWER STEERING STARTED MAKING NOISE DEALER SAID THEY DIDN'T HEAR ANYTHING AND DIDN'T DO ANYTHING AND NOISE IS GETTING LOUDER. THEN SUSPENSION STARED IT MAKING NOISE. TOOK IT TO DEALER AND HAD TIE RODS REPLACED. THEN THE SERVICE AIRBAG PROBLEM CAME BACK AND THIS TIME DIDN'T GO AWAY. TOOK IT TO THE DEALER AND THEY SAID THAT THE HARNESS WAS TO TIGHT AND THEY REROUTED IT SO IT WASN'T TIGHT ANYMORE....

TRANSMISSION STARTED SLIPPING BETWEEN 2ND AND 3RD GEAR THEN TWO DAYS LATER JUST QUIT IN A DRIVE THRU LANE AT A FAST FOOD. COULDN'T GET INTO ANY GEAR. I HAD TO HAVE PEOPLE PUSH IT OUT TO A SAFE LOCATION. TOWED IT HOME. NOW I HAVE A $18,000 PIECE OF SCRAP METAL SITTING IN MY DRIVEWAY. *TR

TL* THE CONTACT OWNS A 2008 GMC ARCADIA. THE CONTACT STATED THAT WHILE TRAVELING 25 MPH, THERE WAS A LOUD POP NOISE FROM UNDER THE VEHICLE. THE VEHICLE THEN BECAME RESISTANT TO ACCELERATION ATTEMPTS. THE CHECK ENGINE LIGHT WAS ALSO ILLUMINATED AND THE VEHICLE WOULD NOT MOVE FORWARD OR WHEN IN REVERSE. THE VEHICLE WAS TAKEN TO THE DEALER AND THE CONTACT WAS ADVISED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE VIN WAS NOT AVAILABLE. THE FAILURE AND THE CURRENT MILEAGES WERE 90,177.

I'VE HAD THREE TRANSMISSIONS IN THIS CAR WITH ONLY 114,000 MILES. WAVE PLATE, TORQUE CONVERTER PROBLEMS. *TR

TL* THE CONTACT OWNS A 2008 GMC ACADIA. THE CONTACT STATED THAT HE NOTICED A PUDDLE OF LIQUID UNDERNEATH THE VEHICLE. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION AND THEY STATED THAT THE TRANSMISSION NEEDED TO BE REPLACED .THE VEHICLE WAS REPAIRED BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 37,960.

TRAVELING APPROXIMATELY 65 MPH IN THE FAR LEFT LANE OF A MAJOR HIGHWAY. GOING UP A SLIGHT INCLINE I TRIED TO ACCELERATE BUT THE CAR WAS NOT REACTING THEN THE RPMS WOULD SHOOT UP BUT THE CAR WOULD NOT REACT. I HAD TO CROSS 3 LANES OF TRAFFIC TO GET TO THE EMERGENCY LANE. THE CAR WOULD NOT GO OVER 20 MPH AFTER THAT AND STRUGGLED AT THAT. I MANAGED TO GET TO A GAS STATION. 1 TOW TRUCK, 1 RENTAL CAR AND NOW $1500 TO REPLACE THE "WAVE PLATES" AND "WAVE HOUSING". ADDITIONAL NOTE - THE CAR BROKE DOWN IN AUGUST 2012 AS WELL. IN THAT INCIDENT THE WATER PUMP HAD TO BE REPLACED. *TR
