2007 GMC ACADIA Power Train Problems

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING AT 65 MPH AND ATTEMPTING TO ACCELERATE, THE VEHICLE RPMS INCREASED BUT THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHO STATED THERE WAS AN UNKNOWN TRANSMISSION FAILURE WHICH CAUSED THE VEHICLE NOT TO SHIFT PROPERLY. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 69,000. UPDATED 09/04/14 UPDATED 9/11/14*CN UPDATED 1/20/2015 *JS

VEHICLE TRANSMISSION FAILED. WAVE PLATE DESTRUCTED RUINING TRANSMISSION. NO WARNING. TRAFFIC BEHIND WAS FORCED TO SLAM ON BRAKES AND SWERVE. CAUSED TRAFFIC JAM. VERY DANGEROUS. KNOWN MANUFACTURING DEFECT BY GM. REFUSE TO RECALL. HUNDREDS OF COMPLAINTS THAT HAVE THE 6T70/75 TRANSMISSION (ENCLAVE, SATURN, SOME FORDS). *TR

ON HIGHWAY, TRANSMISSION WAS STUCK AND WOULD NOT SHIFT. CHECK ENGINE LIGHT TURNED ON. WAS ATTEMPTING TO MERGE ONTO BUSY HIGHWAY AND DUE TO HIGH ENGINE REVVING AND NOT SHIFTING HAD TO KEEP THE VEHICLE UNDER 45 MPH. MERGING WAS DANGEROUS AND HAD TO DRIVE UNDER VERY BUSY CONDITIONS AND LEAVE THE HIGHWAY QUICKLY. DID SO LUCKILY AND RETURNED HOME SAFELY. ONCE HOME WITH SELF-PURCHASED DIAGNOSTICS TOOL READ ERROR CODES P0017, P0716 AND P0700, SOME PERTAINING TO TIMING CHAIN STRETCH (KNOWN ISSUES ON THIS VEHICLE) AND TRANSMISSION PLATE ISSUES (ALSO KNOWN). GM HAS NEVER CONTACTED ME REGARDING THESE AND I CONSIDER THIS VEHICLE UNSAFE WITH VERY LITTLE WARNING ABOUT WHAT APPEAR TO BE 2 MANUFACTURER-KNOWN (GMC) ISSUES REGARDING TIMING CHAIN STRETCH AND FAULTY TRANSMISSIONS RIGHT AT ABOUT THE TIME POWER TRAIN WARRANTIES EXPIRE. WE ARE JUST OVER THE WARRANTY EXPIRATION OF 100,000 MILES ON POWERTRAIN AND ARE STARING AT SIGNIFICANT...

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING 40 MPH, THE VEHICLE STALLED AND THE TRANSMISSION WARNING LAMP ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE TRANSMISSION WAS DEFECTIVE AND NEEDED TO BE REBUILD. THE VEHICLE WAS REPAIRED BUT TWO YEARS LATER THE FAILURE RECURRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 90,000 AND THE CURRENT MILEAGE WAS 150,000.

TRANSMISSION SLIPPING JERKS AND BUMPS WHEN SHIFTING. PASSENGERS NOTED THERE WAS ISSUES ALSO. LOSES POWER GOING UP HILLS. TOOK IT TO COCHRAN PONTIAC FOR TWO YEARS AND DID NOT CORRECT SITUATION, SINCE THERE WERE NO CODES ON THE COMPUTER EVEN THOUGH THE CAR HAD NO POWER AND WAS JERKING. ENGINE LIGHT, ANTILOCK BRAKING, NO REAR SENSORS, AND THE FUEL GAUGE LIGHTS ARE NOW ON AFTER ANOTHER DEALER FIXED TRANSMISSION AND I HAD TO PAY $1,500 AND I SHOULD HAVE NOT PAID ANYTHING. I DID NOT HAVE THESE LIGHTS ON MY DASH BOARD WHEN I WENT TO GET THE TRANSMISSION FIXED AND THE DEALER HAS NOT FIXED THEM. RECENTLY, MY CAR LOST POWER AND DIED ON A BLIND DANGEROUS CURVE AND SHUT DOWN THE ENGINE. I WAS AFRAID TO GET HIT AND FELT MY CAR WAS UNSAFE. WE PUT GAS IN AND WOULD NOT START AND ENGINE WAS HOT. I HAD...

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT WHENEVER SHE ATTEMPTED TO ACCELERATE, THERE WAS A SUDDEN INCREASE OF ENGINE RPMS AND THE VEHICLE FAILED TO GAIN SPEED. ALSO, THE CONTACT MENTIONED THAT THE VEHICLE FAILED TO SHIFT INTO GEAR. THE VEHICLE WAS TAKEN TO THE DEALER. THE TECHNICIAN DIAGNOSED THAT THE TRANSMISSION WAS DEFECTIVE AND NEEDED TO BE REPLACED. IN ADDITION, THE CONTACT MENTIONED THAT BURNING FUMES WERE EMITTED INTO THE VEHICLE. THE CONTACT STATED THAT AFTER INSPECTING THE VEHICLE, SHE NOTICED THAT WIRES WERE BURNING IN THE ENGINE COMPARTMENT. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS NOT AVAILABLE. THE FAILURE MILEAGE WAS 48,000 AND THE CURRENT MILEAGE WAS 48,060.

TRANSMISSION WAS ACTING UP TWO MONTHS AGO SO TOOK TO GM TO GET FIXED. THEY PUT NEW COMPUTER IN AND STATED PROBLEM WAS FIXED. CAR WAS FINE BUT NOW SHAKES VERY BADLY WHEN ACCELERATION FROM 20-40 MPH. *TR

I WAS ON MY WAY TO WORK. STOPPED AT LIGHT. LIGHT CHANGED. I ATTEMPTED TO MOVE AND COULD NOT ACCELERATE OVER 10 MPH. TURNED THE CORNER. HAD TO PULL INTO A BUSINESS PARKING LOT WHICH IS WHERE I WAS STUCK UNTIL A TOW TRUCK CAME BECAUSE I COULD NOT MOVE FORWARD. I WAS TOLD BY THE MECHANIC WHO REPAIRED THE TRANSMISSION THAT I WAS NOT THE ONLY ONE HE HAD SEEN WHO HAD PROBLEMS WITH THIS PARTICULAR TRANSMISSION. ALSO, IF YOU GOOGLE 2007 ACADIA TRANSMISSION, YOU WILL SEE SEVERAL, SEVERAL INDIVIDUALS WITH THE SAME PROBLEM. *TR

DRIVING ALONG AT APPROX. 25MPH AND TRANSMISSION SUDDENLY LOST POWER. THE CAR WAS TURNED OFF AND ON RANDOMLY TO APPLY POWER TO THE TRANSMISSION FOR A COUPLE OF MINUTES TO DRIVE IT BACK HOME. THANK GOD I HAD JUST LEFT HOME! NEVER, EVER RECEIVED A NOTICE FROM GMC NOR THE DEALER REGARDING POWER TRAIN PROBLEMS. THE CAR HAS BEEN SITTING SINCE THEN (NOW GOING ON APPROX 8 MOS. BECAUSE I HAVE NOT BEEN ABLE TO AFFORD APPROX. $3,500 FOR A NEW TRANSMISSION. THE SADDEST PART ... I DON'T EVEN HAVE A NOTIFICATION AS TO WHERE TO TAKE IT TO GET REPAIRED. *TR

VEHICLE WOULD NOT SHIFT PROPERLY AND REVERSE WOULD NOT WORK. HAD GMC FIX THE TRANSMISSION BUT I HAD TO COME OUT OF POCKET AS IT WAS UNDER MILEAGE FOR THE WARRANTY BUT PAST THE DATE BY A FEW MONTHS. TODAY 5/2/14, I'M BEING TOLD THAT THE TRANSMISSION IS GOING OUT AGAIN 1 YEAR AND 4 MONTHS AFTER THEY FIXED IT. GMC SAYS THEY ONLY WARRANTY FOR 1 YEAR. UNSAFE VEHICLE FOR A TRANSMISSION TO BE REPLACED BY GMC TWICE WITHIN 1 1/2 YEARS AND UNDER 115,000 MILES. *TR

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED WHILE DRIVING APPROXIMATELY 40 MPH, THE VEHICLE SUDDENLY STALLED AND THE TRANSMISSION LIGHT ILLUMINATED. THE VEHICLE WAS TOWED TO A DEALER WHO COULD NOT DIAGNOSE THE CAUSE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 62,000. THE VIN WAS NOT AVAILABLE.

2007 GMC ACADIA...IT HAS 62000 MILES ON IT & JUST IN MARCH WE HAD A PROBLEM WITH A METAL ON METAL SCRAPING SOUND(& YOU COULD FEEL IT WHEN YOU BRAKED) LIKE IT NEEDED NEW BRAKES BUT BRAKE PADS WERE LIKE NEW. AND THE SERVICE AIRBAG LIGHT IS ON, THEN SERVICE TRACTION CONTROL MESSAGE, & SERVICE STABILITRACK MESSAGE CAME ON TOO & IT STARTED JERKING WHEN YOU HIT THE BRAKES LIKE THE ABS BRAKES WERE KICKING IN. SO WE TOOK IT TO ROBINSON'S & THEY TURNED THE ROTARS & ROTATED MY TIRES & WHEN I GOT IT BACK IT RODE LIKE A DUNE BUGGY. TOOK IT BACK & SAID IT NEEDED NEW STRUTS CAUSE "SOMETHING" STAYED IN A LOCKED POSITION OR ANOTHER. SO THEN WE GOT IT BACK & THE SCRUBBING NOISE/FEELING CAME BACK WITH THE BRAKES AGAIN SO THEN THEY FINALLY JUST PUT NEW BRAKES ON IT & SO FAR...

TRANSMISSION STUCK IN LOW GEAR CAUSING DANGEROUS DRIVING CONDITION. *JS

WAVE PLATE BROKE AND TRANSMISSION BEING REBUILT. *TR

EVERY SINCE I PURCHASED MY 2007 GMC ACADIA, I HAVE HAD PROBLEMS WITH STEERING ESPECIALLY WHEN IT RAINS AND WATER GETS UNDERNEATH THE TRUCK. I HAVE LOST CONTROL OF THE TRUCK SEVERAL TIMES. THEN THERE WAS A RECALL ON IT FOR THAT REASON. THEY PUT SOME KIND OF PROTECTION BEHIND BOTH OF THE FRONT WHEELS, BUT I CONTINUE TO HAVE PROBLEMS WITH POWER STEERING AND LOSING CONTROL OF THE TRUCK. IT GETS VERY DIFFICULT TO TURN THE WHEEL; IT STIFFENS UP AND YOU CANNOT CONTROL THE TRUCK. THIS HAPPENS EVEN AFTER I HAVE PUT POWER STEERING FLUID IN THE VEHICLE. IT WILL EASE UP A BIT, THEN CONTINUES TO BE DIFFICULT TO TURN AND EVEN MAKES A SOUND WHILE ATTEMPTING TO TURN THE WHEEL. ANOTHER PROBLEM IS THAT SOMETHING KEEPS MAKING THE TEMPERATURE HANDLE GO ALL THE WAY ON HOT AND A TERRIBLE FUME SMELL IS RELEASED AND ITS LIKE...

2007 GMC ACADIA WITH 108,000 MILES. CHECK ENGINE LIGHT APPEARED AND THE TRANSMISSION WENT INTO SAFE MODE AND WOULD NOT SHIFT OUT OF 2ND GEAR. CODE GENERATED WAS THE "SHIFT SOLENOID STUCK OPEN". TRANSMISSION SHOP STATED THAT THE TRANSMISSION WILL TOTALLY FAIL SOON AND NEEDED TO BE REBUILD AT A COST OF $4500. THE TRANSMISSION GUY SAID THAT I WAS LUCKY TO GET OVER 100,000 MILES BECAUSE THEY USUALLY FAIL BETWEEN 80-90,000 MILES. HE STATED IT WAS A HORRIBLE DESIGN FOR A TRANSMISSION AND INADEQUATE PARTS WERE USED INSIDE. NOT AN UNCOMMON PROBLEM FOR THIS VEHICLE. RESEARCHING ALL OF THE COMPLAINTS, THERE SHOULD BE A RECALL. GM'S ATTITUDE IS THAT THE WARRANTY IS UP AND IT'S YOUR PROBLEM, SO YOU MUST PAY FOR OUR DESIGN FLAWS. *TR

WAS DRIVING CAR AND TRANSMISSION STARTED ACTING UP. CAR WOULD SHAKE WHEN SHIFTING GEARS. SERVICE ENGINE LIGHT CAME ON. TOOK TO SERVICE GARAGE AND SAID WOULD NEED TO REBUILD TRANSMISSION. *TR

I WAS COMING HOME WITH MY FIVE CHILDREN WHEN GETTING CLOSE TO HOME MY TRUCK JUST WOULD NOT GO OVER 10 MPH I WOULD PULL OVER FOR CARS BEHIND ME TO PASS AFTER I TRIED TURNING IT OFF AND RESTARTING BUT IT WOULD DO THE SAME GLAD I WAS CLOSE TO HOME THAT I WAS ABLE TO GET THEIR. I GOT HOME SHUT THE TRUCK OFF AND TRIED TO TURN BACK ON AND IT WOULDN'T I HAVE BEEN TOLD THAT IT WAS A SENSOR AND REPLACED IT AND IT STILL DIDN'T WORK KNOW I HAVE BEEN TOLD THAT IT IS THE MOTOR THAT IS BAD IT IS EMBARRASSING TO HAVE A TRUCK IN YOUR DRIVEWAY THAT YOU HAVE NOT BEEN ABLE TO USE AND STILL OWE HAVE THE AMOUNT OF WHAT IT WAS SOLD TO US. THEY ALSO TOLD ME THAT THIS WAS COMMON ON 2007 BECAUSE OF THE FAULTY...

I WAS DRIVING TO THE STORE, GOING DOWN HILL ON THE RIGHT SIDE OF THE ROAD. MID-WAY DOWN A MESSAGE APPEARED ON THE COMPUTER SAYING "ENGINE FAILURE, POWER OFF" AND THE CAR JUST SHUT DOWN WITH OUT WARNING. NO MATTER HOW HARD I PRESSED ON THE GAS THE CAR WAS SHUT OFF. THE STEERING WENT OUT AS WELL AND I HAD TO STAND IN THE SEAT TO USE ALL MY POWER TO TURN THE WHEEL. PREVIOUS TO THIS, THE CHECK ENGINE LIGHT HAD NOT BEEN ON, NO ADVANCE WARNING OF THIS. I HAD BOTH OF MY CHILDREN IN THE CAR AT THE TIME. LUCKILY THERE WAS A BP GAS STATION WITH GARAGE AT THE BOTTOM OF THE HILL, I WAS ABLE TO COAST THE CAR INTO THE GAS STATION WHERE THEY RAN DIAGNOSTIC TESTING AND REPAIRED MY CAR AND RESET THE SENSORS. NINE MONTHS LATER I WAS DRIVING WITH BOTH...

I HAVE A 2007 GMC ACADIA. I HAVE HAD TO HAVE MULTIPLE WORK DON ON THE TRANSMISSION AND YESTERDAY IT SLIPPED OUT OF GEAR WHILE DRIVING. I TRIED TO ACCELERATE AND THE ENGINE REVVED AND THE RPMS WENT HIGH BUT THE TRANSMISSION WOULD NOT SHIFT. HAD I BEEN ON THE HIGHWAY AT A HIGH SPEED THIS COULD HAVE BEEN THE CAUSE OF A SERIOUS ACCIDENT. I TOOK IT TO MY DEALER AND THEY SAID THE TRANSMISSION CONTROL MODULE HAD WENT BAD AND IT COST ME $1400.00...AT 83,00 MILES???? I THINK GMC SHOULD TAKE RESPONSIBILITY FOR THE TERRIBLE WORKMANSHIP OF THEIR TRANSMISSIONS IN THE 2007 ACADIA. *TR

TRANSMISSION FAILURE. 2007 WAS THE FIRST YEAR OF THE GMC ACADIA. AT 94,000 MILES I DON'T THINK THE TRANSMISSION SHOULD FAIL. WHEN I PURCHASED THE CAR IT CAME WITH A 5 YEAR 100,000 MILE POWER TRAIN WARRANTY. I HAVE OWNED THE CAR FOR 7 YEARS. I KNOW GMC HAS MADE IMPROVEMENTS TO LATER MODELS. I FEEL THIS IS A HUGE INJUSTICE. I HAVE BEEN QUOTED $4500.00 TO REPLACE THE TRANSMISSION BY THE DEALER. I HAVE BEEN TOLD BY A REPUTABLE AAMCO SHOP THAT THE ONLY PLACE THIS CAN BE FIXED IS AT THE DEALER BECAUSE THEY HAVE THE CODES TO MAKE THE TRANSMISSION AND ENGINE WORK TOGETHER. *TR

ON MY WAY HOME FROM WORK, IN THE MIDDLE OF TUNNEL TRUCK TURN ON CHECK ENGINE LIGHT, IN PANEL " REDUCED ENGINE POWER" AND REDUCED THE VELOCITY BY ITSELF TO 10MPH. I TURN IT OFF AND ON AGAIN , STARTED RUNNING BUT IN LESS THAN 1 MINUTE RUNNING, DID THE SAME PROBLEM. *TR

WAS PASSING A SLOWER MOVING VEHICLE WHEN TRANSMISSION STARTED SLIPPING SEVERELY. PULLED INTO PARKING LOT AND THEN VEHICLE WOULDN'T MOVE AT FIRST. A COUPLE OF THE GEARS SEEMED TO SLIP IN DRIVE AND REVERSE HAD A SHUTTER. TOOK IT TO A GM DEALER AND THEY SAID ITS A WAVE PLATE IN THE TRANSMISSION THAT IS MESSED UP. *TR

TRANSMISSION FAILURE...FIRST NOTICED CAR HESITATED ACCELERATING WHILE ATTEMPTING TO PASS OR GETTING ON INTERSTATE AND RPMS WOULD JUMP UP TO 4-5K THEN HESITATION IN ACCELERATING BEFORE JUMPING INTO FEAR...THEN LATER INCREASED RPMS AT30MPH AND WOULD NOT ACCELERATE. THIS HAPPENED MANY TIMES BUT WOULD GO DAYS/WEEKS IN BETWEEN INCIDENTS. AFTER TAKING TO SHOP AND RESEARCHING THIS IS A VERY COMMON PROBLEM WITH THIS MODEL...WAVE PLATE FAILURE IN TCM ( POOR QUALITY PART) THIS IS SO DANGEROUS....AFTER FIRST INCIDENT I BECAME MORE AWARE OF HOW THE CAR WOULD BEHAVE AND WAS BETTER PREPARED WHEN IT DECIDED TO JUMP INTO A HIGHER GEAR OR HESITATE. CAR IS BEING REPAIRED NOW AND THANKFULLY MY FAMILY STAYED SAFE. TOO MANY OWNERS WITH SAME PROBLEM FOR THIS SAFETY ISSUE TO BE IGNORED. PLEASE HELP. *TR

PUSHING THE GAS PEDAL THE VEHICLE REVVED UP AND THE GEARS SLAMMED INTO GEAR, ENGINE LIGHT CAME ON AND SEEMS TO HAVE NO FIRST GEAR AS OF NOW. SEEMS IT MAY BE THE WAVE PLATE WITHIN THE TRANSMISSION. *TR

GOING DOWN HIGHWAY VEHICLE ACTED LIKE IT SLIPPED OUT OF GEAR ..ABOUT GOT RUN OVER BY TRANSFER TRUCK BEFORE I COULD GET IT TO SIDE OF ROAD ...TOOK TO SHOP SAID TRANSMISSION NEEDED REPLACED ..APPARENTLY LIKE 100S OF THEM DO ON THE ACADIA. *TR

WHEN BEGINNING TO DRIVE OUR VEHICLE FROM CHURCH THE CHECK ENGINE LIGHT CAME ON AND VEHICLE WOULD NOT DOWNSHIFT, AND SPEED WOULD NOT GET ABOVE 30 MPH. WHEN BROUGHT TO THE DEALERSHIP THE FOLLOWING DAY, WE WERE TOLD WE WOULD NEED A NEW TRANSMISSION. THE VEHICLE ONLY HAS 50K AND SHOULD NOT HAVE HAD THIS ISSUE, AND IT IS A TRANSMISSION SAFETY ISSUE. HAD WE BEEN ON A BUSY HIGHWAY AND THIS INCIDENT OCCURRED, A MAJOR ACCIDENT COULD HAVE TAKEN PLACE. OTHER SITES HAVE LISTED NUMEROUS COMPLAINTS ABOUT THE SAME TRANSMISSION PROBLEM OCCURRING IN VARIOUS ACADIA'S AS WELL. A RECALL SHOULD HAVE BEEN ISSUED AND GM SHOULD PAY FOR THE FULL REPAIR AS IT IS OVER $4,000. *TR

TRANSMISSION HAS FULL FAILURE, DEALERS SAID THAT WAVE PLATE WENT OUT DESTROYING ENTIRE TRANSMISSION. $4300 REPAIR AT GMC DEALERSHIP. *TR

BOUGHT WITH 58K MILES ON IT, 9/2012. PROBLEMS BEGAN THE FOLLOWING APRIL. SITTING AT RED LIGHTS, THE TRUCK WOULD STALL OUT AT ACCELERATION, OCCASIONALLY NOT RESTARTING IMMEDIATELY. DEALERS COULDN'T REPLICATE PROBLEM. PROBLEM BRIEFLY STOPPED, AND NOW IT HAS RETURNED AND IS FAR WORSE. WHILE DRIVING, IT SHAKES AND JERKS LIKE A NEW DRIVER LEARNING TO USE A MANUAL TRANSMISSION. SEVERAL TIMES THE TRUCK HAS SHUT OFF COMPLETELY ON HIGHWAYS WHILE CRUISING AT OR AROUND 70MPH OR ACCELERATING TO PASS SOMEONE, NEARLY CAUSING ACCIDENTS. THIS TRUCK HAS BEEN TOWED HOME 3 TIMES THIS MONTH FROM THIS ISSUE, I REFUSED TO TAKE IT TO A GMC DEALER BECAUSE I CAN'T KEEP PAYING $109 FOR DIAGNOSIS AND THEY SAY THEY DON'T FIND ANYTHING (TWICE ALREADY). I RECENTLY HAD THE VEHICLE SCANNED INDEPENDENTLY AND IT'S GIVEN ME CODES 7EA AND 7E8. THE SECOND CODE DOESN'T GIVE A DIAGNOSIS. IN THE LAST WEEK IT HAS...

MY WIFE AND I WERE ON HWY 78 IN LOGANVILLE GA WHEN THE VEHICLE WOULDN'T SHIFT CAUSING US TO VEER OFF THE ROAD. LUCKILY NO ONE WAS IN THE OTHER LANE. WHEN I GOT TO MY DEALERSHIP I ASKED THE SERVICE WRITER IF THIS WAS A COMMON PROBLEM IN THE ACADIA AND HE SAID VERY CANDIDLY YES. HE FURTHER SAID AS THE MILEAGE GETS HIGHER ON THESE MODELS HE EXPECTS NUMEROUS BREAKDOWNS. MY WIFE IS DISABLED AND THIS IS HER CAR. WHAT IF I HADN'T BEEN DRIVING. IT'S GOING TO TAKE SOMEONE GETTING KILLED BEFORE GM ADMITS THESE TRANSMISSIONS HAVE DEFECTIVE PARTS. IT'S NOT A MATTER OF IF THEY WILL BREAK BUT WHEN. *TR

WHEN PULLING OUT FROM A STOP, THE VEHICLE SHIFTS VERY HARD FROM 1ST TO 2ND GEAR. SOMETIMES THERE IS A LOUD CRUNCHING SOUND AND OCCASIONALLY IT WILL SHUDDER WHILE DRIVING. THE VEHICLE HESITATES ALL THE TIME WHEN TRYING TO ACCELERATE, AND WILL NOT DOWNSHIFT WHEN GOING UP HILLS. ERRATICALLY CHANGES GEARS EVEN WHILE TRAVELING AT THE SAME RATE OF SPEED, LIKE IT IS NOT SURE WHAT GEAR TO BE IN. THE CHECK-ENGINE LIGHT WILL COME ON AND IT WILL NOT CHANGE OUT OF 1ST GEAR, AND IT WILL STAY THIS WAY UNTIL THE VEHICLE IT TURNED OFF AND LEFT ALONE FOR A FEW MINUTES. THEN THE LIGHT WILL GO AWAY AFTER IT IS DRIVEN ABOUT 50 MILES. I HAVE HAD THE SHIFT SOLENOID REPLACED ($450 EXPENSE) WHICH IS THAT THE CODE SAID WAS WRONG, AND THIS DID NOT FIX THE PROBLEM OR HELP ANYTHING. *TR

WAVE PLATE BROKE INTO PIECES IN TRANSMISSION IN NOV 2011 WITH 75,000 MILES. NOW SAME ISSUE WITH TRANSMISSION IN OCTOBER 2013 WITH 102,000 MILES. *TR

WHILE TRAVELING DOWN THE HIGHWAY WITH FAMILY THE CHECK ENGINE LIGHT CAME ON AND THE VEHICLE BEGAN SHAKE AND JERK VIOLENTLY. I PULLED TO THE SIDE OF THE ROAD AND THE VEHICLE WOULD NOT GO INTO REVERSE AND FORWARD MADE A TERRIBLE GRINDING NOISE AND COULD NOT GO OVER 10 MILES AN HOUR WHICH IS VERY DANGEROUS DRIVING AT DUSK. GOT THE CAR HOME AND TOOK TO THE DEALER THE NEXT MORNING. WE WERE 2 MONTHS PAST OUR 100 K 5 YEAR POWER TRAIN WARRANTY AND GM WOULD ONLY GIVE A SMALL DISCOUNT ON A TRANSMISSION REBUILD. NOT ONCE DID THEY ASK ABOUT OUR SAFETY. *TR

THE VEHICLE FIRST STARTED FINE, HOWEVER, COULD NOT SHIFT INTO REVERSE. ONCE STARTING AND TURNING THE VEHICLE OFF THREE TIMES, IT FINALLY SHIFTED INTO REVERSE. THEN ON THE HIGHWAY GOING TO DROP OFF MY KIDS AT SCHOOL, THE VEHICLE THEN WOULD NOT SHIFT HIGHER THEN SECOND GEAR. EACH TIME I STEPPED ONTO THE GAS PEDAL, THE RPM'S WOULD GO UP, BUT THE VEHICLE WOULD NOT GO ANY FASTER THEN ABOUT 30 MPH. OF COURSE, THIS SITUATION IS HIGHTLY UNSAFE, ESPECIALLY WITH SMALL CHILDREN IN THE VEHICLE. AT ONE POINT WHEN I WAS ABLE TO DRIVE MY VEHICLE, AND EVERYONE SAID IT WAS FIXED, I DROVE 3.5 HOURS TO PICK UP MY STEP-DAUGHTER AND WAS LEFT STRANDED THERE, DUE TO THE SAME ISSUE IT WENT IN FOR THE FIRST THREE TIMES. IT HAS BEEN IN AND OUT 9MOSTLY IN) THE SHOP FOR OVER THREE AND A HALF MONTHS, WITH EACH REPLACEMENT...

I'M HAVING CHRONIC TRANSMISSION PROBLEMS I'VE SPENT &2000. SO FAR ON THE TRANSMISSION. THE GMC DEALER HAS BEEN CONSTANTLY TELLING ME I'M HAVING MULTIPLE ISSUES REGARDING THE TOTAL WAVE PLATE OF THE TRANSMISSION, WHICH IS EFFECTING OTHER AREAS OF THE CARE. NOW I'M BEING TOLD THAT MY TRANSMISSION WAS A LEMON-MAKE. THAT IT WAS BUILT FAULTY & GMC KNOWS IT. THEY HAVE HAD THOUSANDS OF COMPLAINTS AND REFUSE TO RECALL THIS TRANSMISSION. THIS IS TOTALLY UNFAIR. I STILL OWE 18,000 ON THIS TRUCK. I'M PAYING TWO MORTGAGES AND I'M WORRIED ABOUT HOW I WILL MAKE IT TO WORK THE NEXT DAY. THE MAKER OF THIS TRUCK SHOULD BE HELD RESPONSIBLE FOR THE FAULTS NOT THE CONSUMER. DO TO THIS ISSUE GM ISSUED AN EXCHANGE PROGRAM BUT THE DEALER SHIPS WON'T ENGAGE IN THIS. PLEASE ASSIST ME WITH THIS ISSUE. *TR

MY 2007 ACADIA, JUST A FEW MONTHS OUTSIDE ITS 5 YR POWER TRAIN WARRANTY, EXPERIENCED A TRANSMISSION FAILURE AT HIGHWAY SPEEDS. IT SUDDENLY STARTED OVER-REVVING AND WOULD NOT SHIFT INTO CERTAIN GEARS. RESEARCHING THIS ON THE INTERNET SHOWS MANY MANY COMPLAINTS ABOUT THE GMC ACADIA. THIS APPEARS TO BE CALLED THE "WAVE-PLATE" FAILURE. UNFORTUNATELY, MOST PEOPLE APPARENTLY HAVE EXPERIENCED THIS BETWEEN 50-70K MILEAGE, WHICH IS EXACTLY WHERE I AM. I WOULD HIGHLY RECOMMEND GMC INSTITUTE A RECALL ON THIS VEHICLE BECAUSE THIS APPEARS TO BE HIGHLY COMMON, AND A SAFETY RISK AT HIGH SPEEDS. *TR

THE TRANSMISSION ON MY ACADIA HAS DIED. MY WIFE WENT TO PICKUP OUR SON FROM A FRIEND'S HOUSE. THE CAR DROVE FINE ON THE WAY OVER. WHEN THEY GOT BACK IN THE CAR, TO LEAVE, THE CAR WOULD NOT GO INTO GEAR. SHE COULD MOVE THE SHIFT LEVER INTO REVERSE BUT THE CAR WOULDN'T GO. THE ENGINE WOULD JUST REV. SHE TURNED THE CAR OFF TO GO ASK FOR HELP. WHEN SHE STARTED IT AGAIN, IT WOULD GO INTO GEAR BUT THE CHECK ENGINE LIGHT WAS ON AND IT DIDN'T SOUND RIGHT. WHEN TRYING TO DRIVE THE CAR, IT WOULD SLIP IN AND OUT OF GEAR AND HAD A WHINING SOUND. WHEN READING THE CODES, I FOUND THE FOLLOWING: P0700 POWERTRAIN - TRANSMISSION CONTROL SYSTEM, P0752 SHIFT SOLENOID "A" STUCK ON, & P0797 PRESSURE CONTROL SOLENOID "C" STUCK ON. I HAVEN'T HAD IT CHECKED BY A MECHANIC YET SO I...

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING 30 MPH, THE VEHICLE STOPPED SHIFTING GEARS AND BEGAN TO JERK AND LUNGE. THE VEHICLE WAS TAKEN TO AND INDEPENDENT MECHANIC FOR DIAGNOSIS WHERE THE CONTACT WAS INFORMED THAT THE TRANSMISSION WOULD NEED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE VIN WAS AVAILABLE. THE FAILURE AND CURRENT MILEAGE WAS 90,000.

VEHICLE WOULD MAKE VERY LOUD SOUND AND THE ENTIRE VEHICLE WOULD JERK WHEN GOING BEYOND 20 MPH, I WAS TERRIFIED OF PUTTING MY CHILDREN IN THIS CAR FEARING THAT I WOULD BE ENTERING THE INTERSTATE OF CARS TRAVELING 70 + MPH AND MY CAR NOT SHIFTING INTO GEAR!! AFTER TAKING IT IN FOR A 3RD TIME. THEY KEPT TELLING ME THAT NO CODES WERE COMING UP AND REFUSED TO LISTEN TO ME. AFTER READING ALL OF THE BLOGS ABOUT THIS HORRIBLE CAR I WENT INTO THE DEALERSHIP INSISTED THAT THE MANAGER RIDE WITH ME IN THE CAR TO FEEL AND HEAR WHAT WAS GOING ON IN WHICH HE DID. I TOLD HIM THAT THE WAVE PLATE WAS THE PROBLEM WITH THOUSANDS OF THESE CARS SO I WAS PRETTY SURE THIS WAS THE PROBLEM. HE SAID DON'T BELIEVE EVERYTHING YOU SEE ON THOSE BLOGS. WELL A FEW DAYS LATER THEY CALLED...

I WAS TRAVELING ON THE INTERSTATE WHEN I HAD LOSS OF FORWARD MOMENTUM AND A CHECK ENGINE LIGHT. THE WAVE PLATE IN THE TRANSMISSION BROKE LEAVING ME AT FREEWAY SPEEDS WITH NO WAY TO ACCELERATE. THIS SOUNDS LIKE A FAIRLY COMMON PROBLEM WITH THIS VEHICLE.

IT ALL STARTED WHEN ATTEMPTING TO ACCELERATE THE CAR TO 30 MPH FROM A STOPEED SPEED AND RPM'S FLEW UP TO 3,000 AND WOULD NOT GO DOWN TO A NORMAL RANGE WHILE CONTINUED ACCERATION OR COASTING. THEN CHECK ENGINE LIGHT POPS ON AND PULL OVER TO TURN CAR OFF TO FIGURE OUT WHAT TO DO. TURN CAR BACK ON AND THERE ARE NO PROBLEMS BUT THE LIGHT IS STILL ON. PROBLEM WOULD SHOW UP RANDOMLY WHEN DRIVING BUT THEN WOULD STOP IF CAR WAS TURNED OFF AND TURNED BACK ON ALMOST LIKE A RESET. THEN STARTED HAVING PROBLEMS WHEN GOING DOWN THE ROAD WHERE RPM'S WOULD GO FROM 1500 TO 3000 AND WOULD JERK CAR DOWN TO 2500 WHEN FOOT WAS TAKEN OFF THE PEDAL. WOULD RANDOMLY GO BACK A FORTH FROM 1500- 3000 DURING CONSISTENT SPEEDS. EVEN WHILE HAVING THESE PROBLEMS IT WAS NEVER AN "EVERY TIME WE DROVE"...

THE TRANSMISSION STARTED SLIPPING WHEN I MERGED ONTO THE HIGHWAY. THE ENGINE RPM WOULD SPIKE TO 4,000 OR 5,000 EVEN THOUGH THE CAR WAS NOT ACCELERATING. I DROVE THE CAR RIGHT TO THE DEALERSHIP WHICH WAS ONLY A MILE AWAY. THE DEALERSHIP LATER CALLED BACK AND STATED THAT I NEED A NEW TRANSMISSION. THIS IS FOR A CAR WITH ONLY 55,000 MILES ON IT! THESE CARS SEEM TO HAVE A COMMON PREMATURE FAILURE WITH A WAVE PLATE THAT IS INTERNAL TO THE TRANSMISSION. I HAD NO CHOICE BUT TO PURCHASE A NEW TRANSMISSION.

WE WERE DRIVING DOWN THE INTERSTATE AND MY CAR COMPLETELY SHUT DOWN...I HAD NO DRIVING POWER. I PULLED OVER TO THE SIDE OF THE INTERSTATE, PUT MY CAR IN PARK, STARTED IT AGAIN, WENT ABOUT 30FT AND IT SHUT DOWN AGAIN. IT WAS TOWED TO A GMC DEALER AND RECEIVED A PHONE CALL THAT I WOULD NEED A NEW TRANSMISSION. IT IS VERY FRUSTRATING BECAUSE I HAVE READ THAT MANY GMC ACADIA'S TRANSMISSIONS HAVE GONE OUT AND THEY ARE NOT DOING ANYTHING ABOUT IT. THERE SHOULD BE A RECALL ON THESE. THE SHOULD STAND BEHIND THEIR 100,000 MILE POWER TRAIN WARRANTY! I HAVE READ THAT THE 2007 AND 2008 MODELS HAVE THE DEFECTS AND THEY FIXED THE DEFECTS IN 2009. *TR

WE WERE HEADING HOME FROM FT. DAVIS AND WHILE TRYING TO ACCELERATE THE ENGINE WOULD JUST REV AND IT DIDN'T SEEM LIKE THE GEARS WERE SHIFTING. WE WERE GOING AT LEAST 60 MPH AND TRYING TO ACCELERATE TO THE SPEED LIMIT. I HAD CONTACTED ONSTAR WHILE WE WERE DRIVING AND THE DIAGNOSTICS CONFIRMED THAT IS WAS THE TRANSMISSION/POWER TRAIN. WE EVENTUALLY ENDED UP IN PECOS, TX AT A GMC DEALERSHIP, WHO TOLD ME, AND ONSTAR, THAT THERE WAS NOTHING THEY COULD DO BECAUSE THEY WERE ALREADY CLOSING FOR THE DAY. WE GOT THERE BEFORE NOON AND THEY STILL DIDN'T WANT TO RUN TESTS OR ANYTHING, BUT THEY DID SAY I COULD LEAVE MY VEHICLE AND THEY COULD WORK ON IT COME MONDAY. WE HAD PUT TRANSMISSION FLUID IN TO SEE IF THAT WOULD HELP, BUT ONCE WE STARTED THE CAR WE NOTICED THAT THE CAR WOULD NOT REVERSE. NEEDLESS TO...

THE FIRST ISSUE WAS THE WATER PUMP, REPLACED IT AND 2 MONTHS LATER OUT WENT THE POWER STEERING PUMP. AT THAT TIME OF REPLACING THE POWER STEERING PUMP THE DEALERSHIP ALSO REPLACED THE RACK AND PINION AND TIMING CHAIN. NOW, IT'S THE TRANSMISSION. GOING ROUNDS WITH GM TO GET THEM TO TAKE CARE OF THE ISSUE IN ITS ENTIRETY. THIS VEHICLE DOESN'T EVEN HAVE 63K MILES ON IT! THIS VEHICLE IS DEFECTIVE IN EVERY WHICH WAY. I'M WORRIED ABOUT WHAT WILL GO OUT NEXT. I WAS LOOKING FOR SOMETHING RELIABLE AND SAFE AND THIS ACADIA HAS BEEN EVERYTHING BUT THAT. I HAVE SEVERAL FRIENDS THAT ARE ALSO EXPERIENCING THE SAME ISSUES. LET THE GAME BEGIN. I HAVE NEVER HAD A VEHICLE THAT I FEEL IS SO UNSAFE AND UNRELIABLE. I AM A HARD WORKING WOMAN WHO DROVE THE SAME CAR FOR 13 YEARS AND HAD NONE OF THE ISSUES THAT...

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING 35 MPH, THE CHECK ENGINE LAMP ILLUMINATED AS THE VEHICLE FAILED TO ACCELERATE. THE VEHICLE WAS NOT REPAIRED OR DIAGNOSED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 75,000 AND THE CURRENT MILEAGE WAS 75,749. PDATED 09/23/13 *BF THE CONSUMER STATED THE FIRST INCIDENT OCCURRED ON 07/2/2013. AFTER ADDING A HALF QUART OF TRANSMISSION FLUID THE VEHICLE RAN NORMAL UNTIL 08/12/2013. *JS

MY WIFE WAS DRIVING THE VEHICLE ON A LOCAL HIGHWAY AT APPROXIMATELY 60 MPH WHEN SHE FELT A JERK IN THE VEHICLE. SHE WAS APPROACHING A STOPLIGHT THAT HAD TURNED RED AND THEREFORE WAS APPLYING THE BRAKE. WHEN SHE ATTEMPTED TO ACCELERATE THE VEHICLE WOULD NOT MOVE. THE HIGHWAY IS VERY BUSY AT THE TIME OF THE INCIDENT AND SHE WAS IN DANGER OF BEING STRUCK BY ANOTHER VEHICLE. SHE WAS FINALLY ABLE TO GET THE VEHICLE IN GEAR AND TURN ONTO A SIDE ROAD AND PHONE FOR ASSISTANCE. THE VEHICLE WAS ABLE TO BE DRIVEN HOME AFTER SITTING FOR A SHORT TIME, HOWEVER I ATTEMPTED TO MOVE THE VEHICLE OUT OF MY GARAGE AND COULD NOT GET IN GEAR. *TR

I WAS DRIVING ABOUT 35MP AND I TRIED TO ACCELERATE BUT COULDN'T, IT WAS IF MY GEARS WERE STUCK AND I WAS DRIVING AN AUTOMATIC! THE CAR WAS REVVING LIKE CRAZY AND DRIVING VERY FUNNY AND ALL I COULD DO WAS SLOW DOWN AND THERE WERE CARS BEHIND ME HONKING AND TAILING ME! THERE WAS NO SIDE OF THE ROAD TO PULL OFF TO SO I PRAYED AND WAS ABLE TO MAKE IT TO A GAS STATION PARKING LOT AND CALLED MY HUSBAND. HE CAME TO MY RESCUE AND WE CALLED CHEVY DEALERSHIP FOR HELP. THE REVERSE WENT OUT IN THE ACADIA AND MY HUSBAND HAD TO PUSH IT IN REVERSE SO WE COULD LIMP IT DOWN TO THE DEALERSHIP (DRIVING UNDER 30MP) THEY SAID THE TRANSMISSION WENT OUT. WE DID PURCHASE AN EXTENDED WARRANTY BUT THAT HAS SINCE EXPIRED SO WE HAVE TO PAY OUT OF POCKET. WE KEEP...

WHILE ON A VACATION TRIP WITH THE FAMILY, MY 2007 GMC ACADIA STARTED TO HESITATE AND BUCK WHEN ACCELERATING FROM A STOP. WHEN I ARRIVED AT MY DESTINATION AND PULLED INTO THE PARKING LOT, WHEN THE TRANSMISSION COMPLETELY STOPPED WORKING WITH NO FORWARD OR REVERSE GEARS. I HAD TO HAVE THE CAR TOWED TO A GMC DEALER AND HAVE A BROKEN 3/5/REVERSE (35R) WAVEPLATE REPLACED IN THE TRANSMISSION. THIS SUDDEN UNANNOUNCED LOSS OF POWER TO THE WHEELS, COULD BE A POTENTIAL CATASTROPHIC EVENT FOR THE CAR PASSENGERS AND OTHER VEHICLES, TRUCKS AND BUSES, IF THIS WERE TO HAPPEN ON A HIGHWAY TRAVELING AT 65 MPH, AS THERE MAY BE NO WAY AVOID GETTING IN AN CHAIN REACTION ACCIDENT WITH THE FOLLOWING TRAFFIC MOVING AT HIGHWAY SPEEDS. THIS COULD BE ESPECIALLY HAZARDOUS IN HIGH VOLUME RUSH HOUR TRAFFIC, AT NIGHT OR UNDER WEATHER IMPAIRED CONDITIONS (I.E, FOG, RAIN OR SNOW). AFTER...

WHILE MY WIFE AND I WERE ON OUR WAY TO COURT TO FINALIZE THE ADOPTION OF A BABY GIRL THE TRANSMISSION IN MY 2007 GMC ACADIA WENT OUT WITH NO WARNING. WE WERE DRIVING DOWN A 2 LANE ROAD GOING OVER A BRIDGE WHEN IT WENT OUT. WE NOW HAVE IT IN THE SHOP WAITING TO SEE HOW MUCH IT IS GOING TO COST TO REPAIR. I WAS LOOKING ON HERE TO SEE IF THERE WERE ANY RECALLS ON THE TRANSMISSION SINCE IT WENT OUT WITHOUT WARNING TO FIND THAT THIS SEEMS TO BE A COMMON PROBLEM WITH THIS YEAR MODEL OF THE ACADIA. I CANT FIGURE OUT WHY GM WILL NOT COMPENSATE ALL OR PART OF THE COST SINCE THIS IS AN OBVIOUS PROBLEM WITH THE YEAR MODEL. IF THERE IS ANY COMPENSATION AVAILABLE OR RECOURSE WE CAN TAKE PLEASE LET US KNOW. *TR
