2007 GMC ACADIA Power Train Problems

The contact owns a 2007 GMC Acadia. The contact stated that while driving at various speeds, the vehicle lost motive power with the battery saver mode activated. The contact stated that the vehicle failed to restart. The vehicle was towed to an independent mechanic on two occasions, where the vehicle was diagnosed, and it was determined that the alternator and battery needed to be replaced. The vehicle was repaired on both occasions; however, the failure persisted. Additionally, the service air bag and transmission warning lights were illuminated. The contact stated that there was smoke coming from the battery. The vehicle had not yet been taken back to the mechanic or a local dealer for further diagnostic test or repair. The manufacturer was made aware of the failure and informed the contact that the warranty had expired. The approximate failure mileage was 63,000.

Mileage: 63,000

when accelerating onto the freeway, hit 55mph and the car just stopped going. it would not go into any gear, turned off car and it still wouldnt go into gear. AAA showed up said "oh, we see this in the acadia all the time" plugged something in under the dash, the check engine light went off and he said "there you go, now it'll work fine, just dont give it hard gas when getting up to speed" turns out the code was a tranny code that when he cleared it the tranny would then work. Its bad enough i have to deal with this leaking A/C unit, 3 cans a week, and that smell is terrible, i cant even get the car up to speed when entering the freeway traffic. please make gmc fix these issues, i know im not the only one with both issues. Thank you.

MY 2007 GMC ACADIA SPONTANEOUSLY CAUGHT FIRE WHILE DRIVING. NO WARNING LIGHTS AND OR NOTIFICATIONS CAME ON. MY CAR BEGAN TO FILL WITH SMOKE FROM THE FLOORBOARD AND SMOKE CAME FROM THE HOOD. THE FRONT END OF THE CAR WAS FULLY ENGULFED IN A MATTER OF MINUTES, TOTAL LOSS.

GMC PLEASE TAKE ACCOUNTABILITY FOR THE SUNROOF LEAK ISSUE! YEARS OF DATA, ALMOST 100 COMPLAINTS, SOMEONE SHOULD ALREADY KNOW ABOUT THIS AND HAVE A SOLUTION! MY CAR HAS SERIOUS LEAKING ISSUES FROM THE SUNROOF ABOVE THE DRIVER, ELECTRICAL TO CABIN DOESN'T ALWAYS WORK EXCEPT DASH LIGHTS, AND HEADLIGHTS/TURN SIGNALS WORK SPORADICALLY. THE LOCKS WORK WHEN THEY'RE IN THE MOOD. ALSO MEANS AC/HEAT WORKS SOMETIMES..I LIVE UP NORTH AND IT'S 24 TODAY. MY WINDSHIELD WIPER FLUID REMAINS EMPTY BECAUSE IT RANDOMLY TURNS ON AND DRAINS OUT: WHICH ALSO MEANS REPLACING MY WIPERS IS A BAD IDEA BECAUSE THEY RANDOMLY TURN ON FOR AT MOST AN HOUR AND DRY WIPING THE WINDOW...AND DESTROYING THE WIPER BLADES. ALL WHEEL DRIVE WON'T WORK, DESPITE MECHANIC SEEING NO ISSUES. I'VE TAKEN DOWN THE MOUNTS AND TRIED TO FLUSH THE DRAINING TUBES MYSELF..AND THEY'RE CLEAR WITH NO LEAKS WHEN I TESTED THE TUBES. I DON'T KNOW WHAT TO DO. I WISH I COULD AFFORD TO FIX THIS, BECAUSE WE NEED THIS VEHICLE; EVERYDAY I'M SCARED TO DRIVE IT! WE WON'T DRIVE AT NIGHT FOR THE RISK OF THE HEADLIGHTS SHUTTING OFF, AND ALWAYS FINGERS CROSSED MY TURN SIGNALS WILL FUNCTION TODAY. I HAVE KIDS! MY FAMILIES NOT RICH, WE CAN'T AFFORD ANOTHER VEHICLE OR THE COSTLY REPAIR, BEING THAT I'M A SINGLE MOM BARELY BUYING BREAD AND PAYING RENT AS IT IS SINCE MY HOURS GOT CUT FROM COVID. I ONLY WANTED A SAFE VEHICLE, I DIDN'T REALIZE I HAD TO BE SPECIFIC AND ASK FOR ONE WITH HEADLIGHTS AND ELECTRONICS WORKING APPROPRIATELY, TOO. I'LL BE SURE TO NEXT TIME I BUY A CAR...WHENEVER THAT LUCKY DAY OCCURS. PLEASE PRAY FOR US.

OVERDRIVE FUNCTION FAULTY IN TRANSMISSION. DURING COLD WEATHER STABILITY TRAC KICKS IN AND WILL NOT REGAIN POWER EVEN THOUGH THERE IS NO BAD ROAD CONDITIONS (SUCH AS SNOW, ICE, OR RAIN) IT SEEMS TO ACTIVATE WHEN THE WEATHER IS COLD. IT BARLEY MOVES INHIBITING NORMAL TRAFFIC FLOW WHICH IS VERY DANGEROUS. FIXED MOON ROOF LEAKS CAUSING THE ELECTRICAL COMPONENTS TO MALFUNCTION AND RAIN WATER DRIPS ON PASSENGERS AND THOROUGHLY SOAKS THE CARPETS LEAVING A MILDEW SMELL.

TL* THE CONTACT OWNS A 2007 GMC ACADIA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE JERKED AND HESITATED WHEN SWITCHING GEARS. THE FAILURE WAS ALSO PRESENT WHILE DRIVING IN REVERSE.

WE GOT THIS 2007 GMC ACADIA AT 100,230 MILES ON AUGUST 2014. NOW IT HAS AROUND 133,800 MILES. AT 115,000 MILES IT STATED TO HAVE ISSUES WHERE IT SAID STABILITY TRACK. THE TRACTION CONTROL TURNS OFF BY ITSELF AND NOT SURE IF THE STABILITY AND THIS ARE THE SAME THING. SOME ELECTRIC PARTS HAVE ALREADY FAILED. THE CHARGING OUTLET AND ELECTRIC WINDOWS DON'T WORK RIGHT. THE PASSENGER SIDE CAN NOT BE PUT DOWN BY DRIVER SIDE. THE REAR RIGHT SIDE CAN ONLY BE PUT DOWN OF UP BY THE DRIVER. THE LEFT REAR DOES NOT WORK WHEN THE DRIVER PUTS IT DOWN OR UP. THE POWER IN THE LIFT GATE IN THE BACK HAS GONE OUT. IT ONLY OPENS OR CLOSES MANUALLY. THERE WAS ALSO A RECALL WITH THE LIFT GATE AND WE GOT IT FIXED. AFTER IT WAS FIXED THEN A WHILE LATER IT WOULD CLOSE ON US AND IT ALMOST HIT US BUT WE REACTED FAST. IT ONLY CLOSED ON US ABOUT THREE TIMES THEN IT STOPPED WORKING. IT WAS RECALL 15240.THE SAFETY ISSUE IS THAT THE STEERING WHEEL GETS HARD TO TURN WHEN MAKING A TURN OR U TURN. IT HAS HAPPENED MANY TIMES AS I AM DRIVING. ONE TIME IS ALMOST MADE ME CRASH INTO A CAR. I HAVE TAKEN IT TO TWO MECHANICS AND IT HAS ENGINE AND TRANSMISSION CODES. FOR JUST THE TRANSMISSION CODES IT WILL COST ME UP TO $4,000. ACCORDING TO THE CARFAX RECORDS IT HAS HAD INTERNAL TRANSMISSION REPAIRS AT 53,543 MILES. I FEEL LIKE THIS CAR POST A SAFETY ISSUE BECAUSE OF THE STEERING WHEEL PROBLEM. WE HAVE HAD THIS CAR FOR 3YEARS AND WE HAVE EXPERIENCED MANY PROBLEMS WITH IT. GM SHOULD PAY FOR THIS FAULTY PARTS.

MY COMPUTERS AND CELL PHONES WERE HACKED AND THE HARASSMENT DIDN'T STOP UNTIL I DISCONNECTED ONSTAR . I NEVER HAD A ACCOUNT TO THIS . TRANSMISSION WENT OUT DURING THE HARASSMENT THEY KNEW AND HEARD EVERYTHING I DID.

THE SUNROOF LEAKS AND CAUSES ELECTRICAL PROBLEMS. SUDDENLY WHILE DRIVING THE POWER STEERING GEARS, RACK, AND BUSHINGS ARE DEFECTIVE CAUSING THE POWER STEERING TO GO OUT DURING LOW SPEEDS. TRIED HAVING IT REPLACED UNDER THE RECALL, HOWEVER, 9 MONTHS LATER THE SAME THING HAPPENED AND NOBODY WANTS TO FIX IT OR ALLOWS FOR THE DEALER TO REPLACE IT AGAIN. THIS IS A MAJOR SAFETY FEATURE THAT SHOULD NEVER BE ACCEPTABLE! ALSO, THE TRANSMISSION ALREADY HAD TO BE REPLACED AND IS GOING OUT AGAIN. THE MANUFACTURE MADE A FAULTY VEHICLE AND SHOULD BE HELD ACCOUNTABLE FOR THESE PARTS AND THE LABOR NOT TO MENTION THE INCONVENIENCE OF HAVING TO FIGHT WITH THE DEALER AND GM TO GET THE PROBLEM CORRECTED.

I BOUGHT A NEW GMC ACADIA IN 2007. JANUARY 8, 2008 GMC DID A SOFTWARE UPGRADE TO MY TRANSMISSION. AT THAT POINT MY MILEAGE DROPPED ABOUT 6 MILES PER GALLON AND DID NOT SHIFT AS NICE AS ORIGINAL. IN LATE SUMMER OF 2014 I NOTICE THAT MY TRANSMISSION WAS NOT RIGHT. ON SEPTEMBER 16, 2014 I HAD TO REPLACE THE TRANSMISSION AT A COST OF $3,999 AT ONLY 123,228 MILES. THIS CAR WAS BUILT AND ADVERTISED TO PULL BOATS AND CAMPERS. I HAVE NOT PULLED ANYTHING EVER WITH THE CAR. IN MARCH OF 2015 I RECEIVED A LETTER FROM GMC THAT THEY WOULD REIMBURSE 2007 GMC ACADIA OWNERS IF THEY HAVE HAD PROBLEMS WITH THE TRANSMISSION. THE CAR MUST BE UNDER 10 YEARS OLD AND UNDER 120,000 MILES. MY CAR WAS UNDER 10 YEARS OLD, BUT OVER ON MILEAGE BY 3,228 MILES. GMC WOULD NOT COVER ANY OF IT.

WE ARE JUST OVER THE WARRANTY EXPIRATION OF 100,000 MILES ON POWERTRAIN AND ARE STARING AT SIGNIFICANT EXPENSE AND A CAR WE JUST DON'T TRUST ANYMORE. *TR

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 TO HAVE IT TOWED TO DEALER AFTER TWO WEEKS FROM GETTING THE TRANSMISSION REPAIRED AND TOLD DEALER TRANSMISSION HAS NOISES IN IT AND ENGINE WAS HOT AND CAR WOULD NOT START. THEY CALLED AND SAID IT WAS OUT OF GAS AND RUNS NOW, HOWEVER, THEY DID NOT ADDRESS THE ISSUES NOTED ABOVE FOR ALL OF THE LIGHTS THAT WERE ON THE DASH BOARD. THE GAS WAS NOT THE ISSUE BEFORE CAR WAS TOWED SINCE WE PUT GAS IN THERE WHEN IT BROKE DOWN. THIS 2007 ACADIA HAS HAD ISSUES SINCE 2011 THAT CONTINUE TO PRESENT AND THIS SUV IS KNOWN TO HAVE MANY RECALLS AND IS UNSAFE. THE CAR WAS TAKEN TO THE DEALER NUMEROUS TIMES WITH COMPLAINTS BY THE CUSTOMER. *TR

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.

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 SO GOOD $1000 LATER! NOW, THIS MORNING I WAS IN A DRIVE THRU & IT FELT LIKE MY CAR WAS IN NEUTRAL WHEN I TRIED TO GO FORWARD & I HAD TO LOOK TO SEE IF I MOVED THE GEARS & THEN I NOTICED THE ORANGE ENGINE LIGHT WAS ON. IT BARELY WANTED TO GO & THE RPMS JUST KEPT GETTING HIGHER & HIGHER & IT WAS STRUGGLING TO MOVE SO I PULLED OVER & HAD ONSTAR RUN DIAGNOSTICS & CODES PO700 & PO716 POWER TRAIN DETECTED MALFUNCTION TRANSMISSIONS & TRANSMISSION NOT PERFORMING AS EXPECTED!! I NOTICED AFTER SHE RAN THE TEST MY CAR SOUNDED LIKE IT CHANGED BACK TO NORMAL WHILE RUNNING SO I CUT IT OFF & BACK ON & IT DROVE OK BACK HOME BUT NOW WE HAVE TO HAVE IT LOOKED AT & I'M JUST SICK TO MY STOMACH OVER THIS! IT LOOKS LIKE IT'S GONNA BE A BROKEN WAVE PLATE & ENDING UP RESULTING IN A NEW TRANSMISSION I CAN NOT AFFORD!!! I KNOW IT'S 2007 BUT WITH SUCH LOW MILEAGE & IN GREAT CONDITION I WOULDN'T THINK IT SHOULD HAVE ALL THESE PROBLEMS ESPECIALLY WITH THE TRANSMISSION!! I HAVE READ SO MANY REPORTS ON THE SAME ISSUES WHICH ARE BEYOND RIDICULOUS CONSIDERING HOW MUCH YOU PAY FOR THESE VEHICLES!!!! THIS IS TOTALLY UNSAFE & NEEDS A RECALL ASAP!!! *JS

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 THE TRUCK IS OVER-HEATING. ANOTHER ISSUE IS THE ELECTRIC: POWER WINDOWS WORK SOMETIMES, RADIO WORKS SOMETIMES, DVD PLAYER WORKS SOMETIMES, ETC. THIS BECOMES ANNOYING TO KNOW THAT YOU HAVE A "SOMETIME" VEHICLE. I WANT A RELIABLE AND SAFE VEHICLE TO RIDE MY FAMILY IN. I ALSO NOTICE THAT SOMETIMES THERE IS A PROBLEM WITH THE IGNITION SWITCH. IT SOMETIMES DELAYS PRIOR TO STARTING. *TR

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

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 MOTOR THAT WAS PUT INTO THEM AS I READ SOME OF THE REVIEWS IT SHOULD BE CONSIDERED AS A RECALL BECAUSE OF THE PRICE THESE TRUCKS GO FOR NEW OR USED SUPPOSE ABLY IT IS A HIGH QUALITY VEHICLE AND ITS SAD THAT THEIR IS SO MANY BAD REVIEWS AND NOTHING HAS BEEN DONE TO HELP ALL THE PEOPLE WHO ARE HAVING THIS ISSUE AS GM KNOWS THIS ISN'T SOMETHING YOU CAN SAY I WILL GET IT FIXED RIGHT AWAY YOU ARE TALKING THOUSANDS OF DOLLARS FOR REPAIRS. *TR

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 OF MY CHILDREN AGAIN, IN NORTH EAST WASHINGTON DC WHEN OUT OF NO WHERE THE SAME MESSAGE APPEARED. I WAS ABLE TO PULL THE CAR OVER TO THE SIDE OF THE ROAD AND RESTART THE ENGINE ONE TIME. I TURNED AROUND TO GO HOME AND ON THE DRIVE HOME THE SAME THING HAPPENED ON A LESS OF AN INCLINE OF A HILL. THE CAR SHUT DOWN COMPLETELY TOWARDS THE TOP OF THE HILL GOING DOWN. SAME AS BEFORE, NO GAS AND NO STEERING ABILITY. I WAS TOO SCARED TO LEAVE THE CAR ON THE SIDE AS CARS COMING OVER THE HILL WOULD NOT HAVE TIME TO STOP BEFORE HITTING US. I PUT THE CAR IN NEUTRAL AND TRIED TO GLIDE DOWN THE HILL TO THE SHELL STATION. THE CAR CUT OUT COMPLETELY AND LOST ALL MOMENTUM SO I HAD TO PUSH THE CAR INTO THE GAS STATION AND WAIT 3 HOURS FOR THE TOW TRUCK TO ARRIVE. IT WENT BACK TO THE BP STATION FROM FEBRUARY AND HAD A NEW BATTERY AND SEVERAL OTHER ITEMS REPLACED. I BOUGHT THIS CAR NEW IN 2007 AND HAVE HAD COUNTLESS BREAKDOWNS AND REPLACEMENTS- TWO TRANSMISSIONS WITHIN THE FIRST 3 YEARS AND REPAIRS. I KEEP UP WITH CAR MAINTENANCE REGULARLY AND DO NO NEGLECT ANYTHING. *TR

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

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.

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

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 FAILED TO START 4 TIMES AND I'VE BEEN KEEPING VIDEO BLOGS TO RECORD WHAT IT IS OR ISN'T DOING. IT IS CURRENTLY SITTING IN MY DRIVE WAY, NOT OPERABLE. GM CUSTOMER SERVICE SAYS THERE ISN'T ENOUGH EVIDENCE TO SUPPORT A RECALL, BUT EVERYONE IS HAVING THE SAME PROBLEMS. TWICE IT STRANDED MY WIFE AND CHILDREN ON INTERSTATES. ON 10/30/13 (ON OUR ANNIVERSARY, OUT OF TOWN NONE THE LESS) IT SHUT OFF AND WE HAD TO GET PUSHED TO THE SHOULDER...VERY EMBARRASSING! SOMETHING MUST BE DONE! EVERYBODY CAN'T BE TELLING THE SAME LIE!

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

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 PART FOR THE TRANSMISSION, IT GOES ON A TEST DRIVE AND THE SAME THING KEEPS HAPPENING. *TR

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 DON'T KNOW THE REAL PROBLEM. THE TOW TRUCK IS TAKING IT TO THE SHOP TOMORROW.

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.

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 ME AND SAID THE WAVE PLATE WAS BAD AND THEY REPLACED IT!!! THIS CAR NEEDS TO BE RECALLED FOR SEVERAL REASONS, POWER STEERING IS BAD AND NEEDED REPLACED, AND IS MAKING THE SAME SOUND AGAIN THAT IT WAS MAKING THE FIRST TIME IT WENT OUT, THE WATER PUMP WENT OUT AND WAS REPLACED. I AM ALMOST TO THE END OF MY EXTENDED WARRANTY AND I HOLD MY BREATH EVERY TIME I DRIVE MY CAR PRAYING THAT MY TRANSMISSION DOESN'T GO OUT AGAIN, HORRIBLE TO HAVE THIS FEELING ON SUCH AN EXPENSIVE VEHICLE, I AM ASKING YOU TO PLEASE RECALL THESE 2007 ACADIA'S BEFORE SOMEONE LOOSES THEIR FAMILY'S LIVES! THANKS SO MUCH. *TR

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.

Mileage: 88,000

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" THING. THEN AFTER A FEW WEEKS OF HAVING THIS PROBLEM A MESSAGE POPS UP SAYING "TRANSMISSION HOT IDLE ENGINE" THAT IS WHEN IT REALLY WORRIED ME. WE TOOK IT TO THE DEALERSHIP TO PAY $199.95 FOR A DIAGNOSTIC TEST STATING THAT THE CLUTCH WAS BAD AND OTHER INTERNAL FAILURES EXSISTED AND WE NEEDED A NEW TRANSMISSION. TO REBUILD WOULD BE $4900 OR A NEW ONE $6200. WITH ALL THE OTHER COMPLAINTS ON HERE REGARDING TRANSMISSIONS ON THE 07 AND 08 ACADIA'S IT SEEMS SOMETHING NEEDS TO BE DONE ON GM'S PART. THIS IS NOT A CHEAP FIX AND IS FRUSTRATING TO SEE ALL THE OTHER PEOPLE DEALING WITH THE SAME PROBLEMS. THANKFULLY WE WEREN'T STRANDED ANYWHERE WITH OUR 2 SMALL CHILDREN. SAFETY SHOULD BE A TOP PRIORITY FOR GM.

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 SAY MY TRANSMISSION NEEDS TO BE REBUILT...WE WERE ABLE TO GET MY CAR BACK HOME AND TWO REPAIR SHOPS BOTH CONFIRMED THAT. THE SECOND GUY EVEN SAID THAT HE'S HAD TO REBUILD/REPLACE AT LEAST 4 TRANSMISSIONS AND I HAD MISSED THE RECALL BY ONE YEAR. FUNNY THING IS I DON'T EVEN REMEMBER BEING NOTIFIED OF ANY TRANSMISSION RECALL, BUT I HAVE RECEIVED OTHERS. I HAVEN'T EVEN FOUND ANY ONLINE. OBVIOUSLY THIS IS AN ONGOING AND DANGEROUS PROBLEM THAT NEEDS TO BE ADDRESSED ASAP! *TR

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 I AM HAVING WITH THIS ACADIA THAT I PAID TWICE AS MUCH FOR! SO, TO ANYONE WANTING TO PURCHASE AN ACADIA, DO RECONSIDER, EVEN AS DEPENDABLE AS YOU FEEL YOUR DEALERSHIP MAY BE...IT WILL BE A LEMON IN THE LONG RUN. BE PREPARED TO GET YOUR GLOVES ON IN THE RING WITH GMC AS I'M CURRENTLY DOING...AS I'M DRIVING A DEALERSHIP LOANER, FOR 2 DAYS NOW...GOOD LUCK! *TR

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.

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 UP ON MAINTAINING THE VEHICLE SO WE WERE SHOCKED THAT THE TRANSMISSION WENT OUT WHEN I WAS DRIVING, THERE WAS NO WARNING AT ALL! I WAS SCARED THAT MY GIRLS AND I WOULD BE HURT! WE WERE QUOTED BETWEEN $3,500 OR $4,800 FOR EITHER REBUILDING OR REPLACING TRANSMISSION. MANY REVIEWS SAY THAT EVEN THOUGH OTHERS HAVE PAID TO RE-DO THEIR TRANSMISSIONS ON GMC ACADIA THAT IT EVENTUALLY HAPPENS AGAIN. WE CAN'T AFFORD TO GET RID OF ACADIA (MANY PAYMENTS STILL) BUT I FEEL UNSAFE KEEPING IT. OTHERS SHOULD BE AWARE OF THE PROBLEM IN CASE IT HAPPENS TO THEM. I'VE NEVER BEEN SO SCARED OR FELT SO UNSAFE BEFORE. *TR

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 A LITTLE RESEARCH, I WAS MADE AWARE THAT THIS IS NOT AN ISOLATED INCIDENT AND GM IS QUITE KNOWLEDGEABLE OF THIS WAVEPLATE TRANSMISSION PROBLEM, IN ALL MODELS WITH THE SAME DRIVETRAIN PLATFORM, BUT HAVE DONE LITTLE TO STEP UP AND REMEDY THE PROBLEM. IF YOU ARE OUT OF WARRANTY (5 YEARS OR 100,000 MILES) YOU ARE GOING TO BE OUT SEVERAL THOUSANDS OF DOLLARS FOR THE REPAIRS, SUFFER A GREAT DEAL OF INCONVENIENCE AND ARE PUTTING YOURSELF AND OTHERS ON THE ROAD AT GREAT RISK. I HOPE THIS WILL HELP BRING THIS ISSUE TO HEAD, AS GM NEEDS TO RECALL AND REPAIR THIS WAVEPLATE TRANSMISSION PROBLEM, AS IT PRESENT A SERIOUS EXPOSURE AND LIABILITY TO INJURE AND HARM THE TRAVELING PUBLIC. *TR

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

WHILE DRIVING AT APPROXIMATELY 25 MPH VEHICLE WAS SHIFTING VERY HARD. THE VEHICLE CONTINUED TO HAVE ISSUE SHIFTING. AT ANOTHER TIME WAS DRIVING VEHICLE AND STOPPED AT A TRAFFIC LIGHT. UPON LIGHT TURNING GREEN PUSHED ON THE ACCELERATOR AND THE VEHICLE WOULD NOT GO, TRANSMISSION WOULD NOT SHIFT INTO GEAR. VEHICLE HAS 83,000 MILES AND NOW THE TRANSMISSION NEEDS TO BE REPLACE. SEEMS TO BE A FREQUENT ISSUE WITH THIS VEHICLE MODEL. GM SHOULD RECALL THIS TRANSMISSION!! *TR

WE PURCHASED THIS ACADIA USED IN APRIL 2010 WITH ABOUT 40,000 MILES. IN EARLY JULY 2012 THE TRANSMISSION WENT OUT. THIS HAS BEEN REPAIRED UNDER OUR EXTENDED WARRANTY AS OF JULY 15, 2012. ON AUGUST 1, 2013, OUR TRANSMISSION WENT OUT AGAIN. DURING THE FIRST YEAR OF OWNING THIS VEHICLE, WE HAVE HAD THE WINDSHIELD WIPERS OPERATING ERRATICALLY AND THE RADIO WILL NOT ALWAYS SHUT OFF WHEN THE ENGINE HAS BEEN STOPPED AND DRIVER'S DOOR OPENED & CLOSED (POSSIBLE ELECTRICAL PROBLEMS). WE'VE ASKED OUR GMC DEALERSHIP TO ADDRESS THE ELECTRIC, BUT EACH TIME THEY SAY NOTHING SHOWS ANY ERRORS ON THEIR COMPUTER TESTS. WITH THE RECENT ISSUE IN A LITTLE OVER A YEAR ON THE TRANSMISSION (AGAIN!) WE HAVE FOUND NUMEROUS SITES FROM OTHER 2007 ACADIA OWNERS STATING THE SAME PROBLEMS AND THAT IT IS REPETITIVE. IF THIS HAS BEEN A WIDESPREAD AND KNOWN PROBLEM, THIS WAS NOT SHARED BY OUR DEALERSHIP. GIVEN OUR VEHICLE HAS LESS THAN 100K MILES AND WILL LIKELY HAVE A 3RD TRANSMISSION IN ITS 6 YEAR AGE, THIS IS NOT A VEHICLE I FEEL SAFE HAVING MY WIFE AND 3 YOUNG CHILDREN CONTINUE TO RIDE IN. UNFORTUNATELY, OUR OPTIONS ARE VERY LIMITED FINANCIALLY TO FIND A VEHICLE ALLOWING FOR THE AMOUNT OF SPACE NEEDED FOR 2 CAR SEATS IN ADDITION TO OUR 9 YEAR OLD BOOSTER SEAT (NORMALLY CANNOT SEAT THEM IN ONE ROW SIDE BY SIDE BY SIDE). AT THIS POINT, WE ARE RESEARCHING ALL OPTIONS TO GET OUT OF THIS ACADIA AS WE CANNOT SINK MONEY INTO THIS VEHICLE TO KEEP IT RUNNING SAFELY AND NOT KNOW IF THE TRANSMISSION WILL CONTINUE TO GO OUT. *TR

WHEN I PURCHASED THE VEHICLE THERE WAS A NOTICEABLE WHINE IN THE STEERING. I ASKED THE SALESMAN AND HE SAID THAT NOISE WAS TYPICAL WITH ACADIA'S AND THERE WAS NO ISSUE WITH THE CAR. WHEN I TOOK IT IN FOR AN OIL CHANGE AT A DIFFERENT DEALER RIGHT BEFORE WE LEFT ON VACATION, I WAS TOLD THE POWER STEERING PUMP WAS GOING OUT AND NEEDED TO BE REPLACED IMMEDIATELY. DID THAT EVEN THOUGH WE WERE DELAYED GOING ON VACATION AND SUBSEQUENTLY HAD IT REPLACED TWO MORE TIMES AS WELL. ALSO HAVE HAD LEAKS IN THE SUNROOF THAT CONTINUE TO RETURN, AND HAVE NOW MESSED UP MY POWER WINDOW CONTROLS TO THE POINT THAT I CAN NOT CONTROL ANY OF THE OTHER WINDOWS FROM THE DRIVERS SEAT. HAVE HAD TO REPLACE THE WATER PUMP, FRONT STRUTS, AND NOW THE SOLENOIDS ARE BEING REPLACED AS WELL. WHEN I PURCHASED MY CAR IT HAD RIGHT AT 54K MILES ON IT AND I HAD AN EXTENDED WARRANTY, THAT COVERED MY POWER STEERING PUMP ISSUES, BUT I HAVE HAD TO DEAL WITH THE REST. I WILL HAVE NOW PUT ALMOST $3K INTO REPAIRS THAT SEEM TO BE VERY TYPICAL WITH THIS CAR, BASED ON WHAT I HAVE READ ON THE INTERNET. *TR

WE WERE 50 MILES FROM HOME ON A VACATION WITH OUR TWIN 2 YEAR OLDS AND 7 YEAR OLD WHEN THE TRANSMISSION WENT OUT. FIRST IT SAID "TRANSMISSION HOT, LEAVE ENGINE ON IDLE". SO WE SAT FOR 10 MINUTES. IT WENT AWAY, THOUGHT WE WERE OK, KEPT DRIVING FOR ABOUT ANOTHER 15 MINUTES AND COMPLETE FAILURE. WE WERE STRANDED FOR 3 HOURS IN THE MIDDLE OF NOWHERE (DETOURED ROAD TOOK US BACK ROADS). COULDN'T GET A TOW. HUNGRY, HOT AND THIRSTY LITTLE BOYS. COPS GOT CALLED ON US BECAUSE WE ENDED UP BEING ON SOMEONE'S PROPERTY WE SHOULDN'T BE. TOTAL MESS. EMBRACED, HOT, IRRITATED AND SO ANGRY. $15,000 OWED ON A VEHICLE THAT WE HAVE TO REPLACE A $3600 TRANSMISSION! SERIOUSLY?!?! WHAT WOULD HAVE HAPPENED IF I WAS BY MYSELF AND MY HUSBAND WASN'T WITH ME. OR IT CAUSED A WRECK WITH ME AND MY CHILDREN IN THE CAR. GMC WON'T HELP BECAUSE WE ARE PASSED WARRANTY. APPARENTLY AFTER DOING RESEARCH THIS IS A COMMON PROBLEM. IF I FIX IT I'M STUCK WITH A CAR I DON'T TRUST AND OWE TOOOOO MUCH MONEY ON FOR WHAT IT'S WORTH AND OH GREAT PUT IN THE SAME [XXX] TRANSMISSION THAT FAILED THE FIRST TIME AND COULD HAPPEN AGAIN. WILL NEVER OWN ANOTHER GMC- RIDICULOUS AND NEEDS TO BE LOOKED INTO. THIS HAPPENS FAR TOO MUCH FOR THERE NOT TO BE A LAWSUIT OR RECALL ON THIS ITEM. ABSOLUTELY RIDICULOUS! PLUS OBVIOUSLY NO VACATION, OUR MONEY GOT TO GO INTO A CAR WE SHOULDN'T HAVE TO PUT THIS MUCH MONEY INTO. DISAPPOINTED ON SO MANY LEVELS.

AS I WAS TAKING A FAMILY TRIP, I WAS TRAVELING THROUGH SOME STEEPER GRADES WHEN THE VEHICLE RPMS WERE REGISTERING VERY HIGH AND WOULD NOT SHIFT TO LOWER GEARS EVEN WHEN MY TRAVEL SPEED SLOWED DOWN. ON MY DISPLAY A WARNING CAME ON SAYING TO IDLE THE VEHICLE TRANSMISSION HOT' I THEN PULLED OVER IN A VERY BUSY ROAD AND LET THE VEHICLE IDLE FOR 10 MIN IT THEN SHUT OFF BUT HAD VERY WEIRD DRIVING CHARACTERISTIC THE REST OF THE WAY. THIS INCLUDED WHEN SHIFTING FROM SECOND GEAR TO THIRD IT FELT LIKE THE CLUTCH WOULD POP AND JERK THE VEHICLE WHEN IT DID SHIFT. THANKFULLY AS WE GOT CLOSER TO A TOWN THE VEHICLE ENGINE LIGHT CAME ON AND WE IMMEDIATELY CONTACT ONSTAR AND THEY GAVE US THE CODES ALL RELATING TO THE VEHICLE WAVE PLATE FAILURE. I THEN HAD TO TAKE IT TO A DEALER OUT IN THE TOWN WE WERE VISITING AT THE TIME WHICH WAS A MAJOR HEADACHE. THIS WAS VERY DISAPPOINTING CONSIDERING THE VEHICLE BARLEY HAD OVER 50,000 MILES AND GMC IS SUPPOSED TO BE A UPGRADE FOR GM. SHAME ON THEM FOR NOT RECALLING ALL 2007-2009 MODELS TO REPAIR THIS ISSUE. NEEDLESS TO SAY GM DID OFFER TO HELP WITH REPAIR COST ONLY CAUSE THEY KNOW IT'S A KNOW ISSUE WHICH I APPRECIATE BUT THE FACT IS WITH THAT LOW OF MILES ON THE VEHICLE THAT SHOULD HAVE NEVER HAPPENED IN THE FIRST PLACE. *TR

DRIVING HOME FROM THE BEACH WITH MY FRIEND, NO SERVICE LIGHTS WERE ON. WHILE DRIVING ON THE GARDEN STATE PARKWAY MY CAR WAS BECOMING SLUGGISH ON THE PICKUP WHILE CHANGING LANES. A COUPLE EXITS DOWN THE ROAD THE CHECK ENGINE LIGHT CAME ON ALONG WITH A MESSAGE - "TRANSMISSION HOT, IDLE ENGINE". I SAFELY PULLED THE CAR OVER 2 EXITS AWAY INTO THE RESTSTOP AND SHUT THE CAR OFF. I WAITED APPROXIMATELY 20-25 MINUTES AND RESTARTED THE CAR, ALL SERVICE LIGHTS WERE NOW GONE. ME AND MY FRIEND DECIDED TO NOW CAUTIOUSLY DRIVE THE CAR HOME SINCE ALL THE SERVICE WARNINGS HAD GONE AWAY. AS WE BEGAN TO PULL OUT OF THE RESTSTOP THE VEHICLE COULD NOT ACCELERATE I THEN WAS STUCK ON THE SIDE OF THE EXPRESS LANE ON THE PARKWAY. SINCE THIS INCIDENT I HAD THE VEHICLE CHECKED AND IT TURNS OUT MY ENTIRE TRANSMISSION IS BROKEN, NOT ONE SALVAGEABLE PART TO REBUILD MY OWN TRANSMISSION. I FIND THIS EXTREMELY RIDICULOUS THAT A CAR WITH 63,000 MILES THAT IS SUPPOSED TO BE OF GOOD QUALITY IS HAVING THIS PROBLEM. I HAVE ALSO FOUND A TRANSMISSION PROBLEMS WEBSITE/BLOG RANTING ABOUT THEIR TRANSMISSIONS PROBLEMS IN 2007-2008 GMC ACADIA VEHICLES ALL WITH 60,000-72,000 MILES. CLEARLY THIS IS A PROBLEM THAT NEEDS TO BE ADDRESSED, THIS IS EXTREMELY UNSAFE AND UNACCEPTABLE. A RECALL SHOULD BE ESTABLISHED FOR THIS TRANSMISSION PROBLEM, THIS NEEDS TO BE LOOKED INTO IMMEDIATELY. *TR

CAR SHUT DOWN WHILE I WAS DRIVING. AFTER AWHILE IT STARTED BACK UP BUT IT WOULD ONLY GO ON FIRST GEAR SO I COULD GO MORE THAN 20MPH. THEN WHEN I WENT HOME, THE CHECK ENGINE LIGHT CAME ON AND THE REVERSE DID NOT WORK. I HAVE READ ALOT OF COMPLAINTS ABOUT THE SAME PROBLEM WITH 2007 ACADIAS.

STARTED THE VEHICLE THIS MORNING WITH REMOTE START, GOT IN AND PUSHED THE KEY FORWARD. AS I LEFT THE APARTMENT COMPLEX ON MY WAY TO THE POST OFFICE, I NOTICED MY ACADIA STARTED HAVING PROBLEMS SHIFTING PAST 20MPH. I TOOK IT TO A LOCAL TRANSMISSION SHOP AND WHEN THEY DRAINED THE FLUID, THE FLUID WAS BURNT REQUIRING THE TRANSMISSION TO BE OPENED UP. I HAVE STILL NOT HAD THE TRANSMISSION MANIPULATED PAST THE FLUID DRAINAGE. I EVEN TOOK VIDEO OF THE SPEEDOMETER AND RPM GAUGE WHILE IT WAS HAVING TROUBLE SHIFTING. *TR

VEHICLE IS HARD SHIFTING FROM 1ST TO 2ND GEAR. HAD SERVICED WITH NEW TRANSMISSION FLUID ON 7/2/13. ON 7/5/13 VEHICLE WOULD NO LONGER SHIFT AT ALL WHILE TRAVELING ON THE FREEWAY ON OUR WAY TO FAMILY VACATION TO HILTON HEAD SC. IT WAS TOWED TO PARKS CHEVROLET IN CHARLOTTE, NC WHERE TRANSMISSION WAS DISASSEMBLED WITH PARTS REPLACED AND REBUILT. UPON DEPARTURE OF PICKUP VEHICLE IS STILL SHIFTING HARD FROM 1ST TO 2ND GEAR (AROUND 20-25MPH) AND WE HOPE TO MAKE BACK HOME TO OHIO SAFELY. I'VE RESEARCHED THIS ISSUE IS COMMON IN GMC ACADIAS.

THE CAR SUDDENLY LOST POWER ON THE INTERSTATE. IT LOCKED DOWN INTO "LIMP HOME" MODE. WE HAD CRAWL ALONG THE BERM AT 30 MPH. THE PROBLEM WAS DIAGNOSED BY GM AS TRANSMISSION FAILURE DUE TO FAILING OF THE WAVE PLATE. THIS WAVE PLATE IS A KNOWN PROBLEM TO GM BUT AS OF NOW NO RECALL HAS BEEN ISSUED. I HAVE READ ONLINE BLOGS ABOUT THIS ISSUE AND IT IS A FREQUENT AND UNSAFE FAILURE OF THIS DRIVE-TRAIN. OUR CAR IS OUT OF WARRANTY BY YEARS BUT ONLY HAS 84K MILES ON IT. GM HAS OFFERED US A 50/50 SPLIT ON THE REPAIR WHICH THEY WOULD NEVER DO IF THEY WERE NOT AWARE OF THIS ISSUE. I THINK IT SHOULD BE THEIR FULL RESPONSIBILITY. PLEASE INVESTIGATE, THANK YOU. *TR

DRIVING UP HILL, LOOSING POWER, FINALLY MADE IT UP HILL CAR JUST STOPPED - ALMOST LIKE IT WAS IN NEUTRAL GEAR. COULDN'T GO ANYWHERE, CAR STARTED RIGHT UP AND WHEN I PRESSED ON GAS IT REVVED UP LIKE IT WANTED TO GO, BUT NO MOVEMENT. STILL LIKE IN NEUTRAL GEAR. FOUND OUT THAT LOTS OF 07 AND 08 ACADIA OWNERS HAVE HAD ISSUES WITH THE WAVE PLATE (WHICH IS WHAT MECHANIC AT DEALERSHIP TOLD ME IT IS). AND THE POWER TRAIN, WHICH ENDS UP MAKING THE TRANSMISSION FAIL. THERE ARE FAR TOO MANY ACADIAS OWNERS OUT THERE WHO HAVE HAD THESE ISSUES. I THINK IT'S WRONG THAT GMC DOESN'T INVESTIGATE OR RECALL THE CARS FOR THIS COST. I CALLED GMC CUSTOMER SERVICE AND FEEL AS IF THEY DON'T TRULY CARE, THEY JUST WANT TO SNUB OFF THE ISSUE AND TELL YOU TO HAVE A GREAT DAY! MY DAD WORKED FOR GMC FOR 20 YEARS, AND I ALWAYS HAD A HIGH OPINION OF THEM UP UNTIL NOW. I AM VERY DISAPPOINTED IN THEM. I FEEL LIKE THEY HAVE LOST THEIR LOYAL CUSTOMERS. BECAUSE OF THIS I WILL NEVER AGAIN BUY GMC WHICH IS A SHAME BECAUSE THAT'S ALL MY DAD BOUGHT IN THE PAST IS GMC. I AM GRATEFUL THAT THE CAR DIDN'T GIVE OUT WHILE I WAS GOING UP THE HILL AND I DIDN'T HAVE MY KIDS IN THE CAR. LUCKILY I WAS ABLE TO MAKE IT UP THE HILL. I FEEL GMC SHOULD STEP UP AND INVESTIGATE THIS ISSUE AND REPLACE THEM WITH MORE QUALITY PARTS. I FEEL AS IF THE ACADIA IS VERY CHEAPLY MADE. *TR

THIS ISSUE STARTED WHEN I WAS DRIVING DOWN THE ROAD AT 35MPG. THE ACADIA TRIED TO SHIFT INTO A HIGHER GEAR BUT CLUNKED VERY LOUDLY AND JOLTED THE WHOLE CAR. FROM THAT POINT FORWARD THE VEHICLE WAS STICK IN 3RD GEAR. IT WOULDN'T UP SHIFT OR DOWN SHIFT. THE CAR LIMPED HOME BUT STARTING ON HILLS OR AT STOP SIGNS WAS ALMOST IMPOSSIBLE. ONCE I GOT THE CAR HOME I CHECKED THE TRANSMISSION FLUID. TRANSMISSION FLUID OK. I THEN TESTED THE CAR AGAIN BY TRYING TO BACK OUT OF THE DRIVEWAY. THE TRANSMISSION MADE A LOUD GRINDING NOISE AND WOULD NOW LONGER MOVE IN REVERSE. I HAD THE CAR TOWED FROM MY HOUSE TO A LOCAL TRUSTED MECHANIC. THE MECHANIC STATED THAT THE WAVEPLATE FAILED. HE ALSO SAID THAT THIS WAS A KNOW DEFICIENCY IN THESE VEHICLES AND THAT THE TRANSMISSION WOULD NEED TO BE REPLACED OR REBUILT. I HAD TO SPEND $3950 TO REBUILD THE TRANSMISSION ON A 2007 VEHICLE WITH 80000 MILES. I WOULD APPRECIATE A REIMBURSEMENT FROM GM FOR THIS OBVIOUS QUALITY PROBLEM. *TR

WHILE AN HOUR FROM HOME, I WAS DRIVING THROUGH A TOWN AND SUDDENLY COULD GET NO "PICKUP" TO START AFTER STOPPING AT A STOPLIGHT. I WAS JUST SITTING THERE IN THE INTERSECTION WHILE TRAFFIC DROVE AROUND ME. I CONTINUED TO MY DESTINATION THIS WAY, BARELY ABLE TO GET GOING AFTER STOPPING. THEN WHEN COMING HOME I HAD "PICKUP" BUT THE VEHICLE WAS SHIFTING IMPROPERLY. I TOOK IT TO THE DEALER AND THEY DIAGNOSED A BROKEN WAVE PLATE AND SAID IT NEEDED A NEW TRANSMISSION. AFTER READING ABOUT ALL THE OTHER ACADIA OWNERS WHO ARE ALSO HAVING THIS PROBLEM, I BELIEVE THE PROBLEM NEEDS TO BE ADDRESSED BY GMC. I DROVE MY CAR AFTER I WAS TOLD IT NEEDED A NEW TRANSMISSION, AND THE TRANSMISSION FAILED IN A BIG WAY WHILE I WAS DRIVING DOWN THE ROAD. SUDDENLY I WAS PUSHING THE GAS PEDAL, BUT NOTHING WAS HAPPENING - MY VEHICLE WAS JUST COASTING. I THINK THIS IS A HUGE SAFETY ISSUE AND THAT THERE SHOULD BE A RECALL TO FIX THESE FAULTY WAVE PLATES. *TR

IT IS OUR UNDERSTANDING THAT THE MOTOR AND TRANSMISSION HAD TO BE REMOVED. ON MAY 18TH 2013 I WAS DRIVING AND THE CAR MADE A LOUD NOISE AND DECELERATED DOWN TO 25 MPH WITH A HIGH RPM. AT THAT POINT I PULLED OVER. I NOTICED THE CAR HAD NO REVERSE. I BROUGHT THE CAR TO THE LOCAL GM DEALER. TODAY THEY CALLED AND SAID THE TRANSMISSION IS SHOT. CURRENT MILEAGE 55,308. WAITING TO HEAR BACK ON EXACT ISSUE. AFTER READING ONLINE THIS IS A KNOW DESIGN FLAW AND HAS BEEN SINCE CORRECTED. I SHOULD NOT HAVE TO PAY FOR GM'S DESIGN FLAWS.

NO SPEED ENTERING THE FREEWAY AND THEN REVERSE SHOT THE CAR FORWARD INTO A FRONT YARD AND ALMOST INTO A HOUSE. I ENTERED THE FREEWAY AFTER PICKING MY 4 YEAR OLD UP FROM PRE-SCHOOL WITH MY 1 YEAR OLD ALSO IN THE CAR. THE CAR WOULD NOT GAIN SPEED AND RPMS SPIKING. NEARLY GOT IN AN ACCIDENT MERGING ONTO THE FREEWAY, EXITED FIRST OFFRAMP, PULLED INTO NEIGHBORHOOD AND TURNED INTO DRIVEWAY TO DO A THREE POINT TURN TO PARK ON THE SIDE OF STREET. PUT THE CAR IN REVERSE LIGHTLY TAPPED THE PEDAL, AND INSTEAD IT SPED FORWARD AS THOUGH THE GAS PEDAL WAS PINNED TO THE FLOOR. WE WENT DEEP INTO THE FRONT YARD OF HOUSE STOPPING JUST SHORT OF THE HOUSE. AAA CAME AND TOWED THE CAR TO THE CLOSEST GM DEALER. AAA DRIVER TESTED REVERSE AND IT WOULD ONLY GO FORWARD. HE SAID HE HAD NEVER SEEN ANYTHING LIKE IT. SO GRATEFUL THIS DIDN'T HAPPEN MINUTES BEFORE IN THE PRESCHOOL PARKING LOT WHICH IS A U SHAPE WHERE THE PARENTS LINE UP AND THE TEACHERS BRING THE KIDS OUT. THE EXPERIENCE WAS TERRIFYING. WE PARKED NEXT TO AN ACADIA YESTERDAY AND MY 4 YEAR OLD SAID "MOMMY WE SHOULD TELL THEM THEY HAVE A BAD CAR." CALLED GM IMMEDIATELY AND EVERY DAY SINCE (2 WEEKS) - NO RESPONSE, I AM JUST SHUFFLED BETWEEN REPRESENTATIVES. MY CAR IS STILL SITTING IN THE DEALER'S LOT. MY CAR ALSO HAD A PURGE VALUE PROBLEM CAUSING IT NOT TO START AFTER GETTING GAS, AND A POWER STEERING PROBLEM. IT IS ONE THING FOR THE TRANSMISSION TO FAIL AT 64,000 MILES AND ANOTHER FOR IT TO ALMOST DRIVE YOU THROUGH SOMEONE'S HOUSE. GM DOES NOT SEEM TO CARE. *TR

ON THIS PARTICULAR DAY I WAS MERGING ON TO THE FREEWAY (WHICH SPEEDS OF OTHER TRAFFIC WAS UPWARDS OF 65 MPH). I ATTEMPTED TO ACCELERATE AND IN DOING SO WAS UNABLE TO SWITCH GEARS.

THE TRANSMISSION ON OUR '07 ACADIA WENT OUT AFTER ONLY 67,000 MILES. WE HAD TO PAY OVER $3,000 OUT OF OUR OWN POCKETS TO GET IT REPAIRED BECAUSE IT WAS OVER THE FIVE YEAR WARRANTY PERIOD EVEN THOUGH IT WAS STILL WELL UNDER THE MILEAGE LIMIT. WHEN YOU PAY OVER $30,000 FOR A VEHICLE YOU EXPECT IT TO LAST LONGER THAN OURS DID WITHOUT HAVING TO PAY THOUSANDS MORE TO KEEP IT OPERATIONAL. A FEW MONTHS AFTER GETTING THE DRIVE TRAIN REPAIRED WE ARE EXPERIENCING CAMSHAFT/CRANKSHAFT ISSUES. THE VEHICLE IS FUNCTIONING AT ABOUT 60% OF ITS ORIGINAL POWER. WE CAN ONLY ASSUME THAT THIS WILL ENTAIL ANOTHER COSTLY REPAIR. *TR

ENGINE LIGHT ON VEHICLE, THE VEHICLE WILL NOT SHIFT INTO GEAR - HAPPENED THREE TIMES HAD TO PULL OFF SIDE OF ROAD TO NOT GET HIT FROM OTHER VEHICLES AND 5 YEAR OLD WAS ALSO IN CAR WITH ME. HAD TO SHUT OFF THE CAR MULTIPLE TIMES TO GET STARTED AGAIN AND FOR IT TO FINALLY SHIFT INTO GEARS. TOOK CAR TO DEALER AND THEY REPLACED TRANSMISSION CONTROL MODULE VALVE. ON 4/1/13 CAR WOULD NOT GO INTO REVERSE ON INCLINE. HAD TO DRIVE FORWARD AND REVERSE ON FLAT AREA, DEALER NOW SAYS THEY FOUND BROKEN WAVE PLATE AND BURNED 3-5 REVERSE CLUTCH. ALSO FOUND INTERNAL DEFECT PARK OF VALVE BODY. CAR IS ONLY 5 YEARS OLD AND HAS ONLY 55 THOUSAND MILES ON IT. SAW OTHER ISSUES ON THIS DATABASE ALL WITH BROKEN WAVE PLATES ON 07 ACADIAS. PAID THOUSANDS OF DOLLARS TO GET THIS FIXED. *TR

TL* THE CONTACT OWNS A 2007 GMC ACADIA. THE CONTACT STATED THAT THE VEHICLE WOULD NOT ACCELERATE OVER 40 MPH. IN ADDITION, THE GEAR SHIFTER COULD NOT BE MOVED INTO REVERSE. THE CHECK ENGINE WARNING LIGHT WAS ALSO ILLUMINATED. THE VEHICLE WAS TAKEN TO DEALER FOR INSPECTION AND THE CONTACT WAS ADVISED THAT THE TRANSMISSION NEEDED TO BE REPLACED. THE TRANSMISSION WAS REPLACED. THE MANUFACTURER WAS NOT MADE AWARE OF FAILURE. THE FAILURE AND CURRENT MILEAGE WAS 87,400.

AFTER SPENDING $370.51 AT MY LOCAL GMC DEALER FOR STABILITRAK ERRORS RESULTING IN LOW FUEL INPUT INTO THE ENGINE, WITH A MAXIMUM SPEED ALLOWABLE AT 35 MPH, MY 2007 GMC ACADIA IS ONCE AGAIN EXPERIENCING STABILITRAK ERRORS. THEY GENERALLY OCCUR WHEN I ROLL TO A STOP AT A STOPSIGN OR STOPLIGHT, BUT I AM VERY CONCERNED THAT THE TRANSMISSION WILL REDUCE SPEED WHEN I TRAVEL THE INTERSTATE. MY LOCAL GMC DEALER CLAIMED THIS PROBLEM WAS CAUSED BY A "CAM EXHAUST POSITION SENSOR FAULT" AND REPLACED THE "CAM EXHAUST POSITION SENSOR" ON 3-20-13 FOR $370.51. FOR ONE WEEK THIS REPAIR WORKED AND THERE WERE NO STABILITRAK ERRORS. TEN DAYS LATER, MY 2007 GMC ACADIA FWD IS WORSE THAN EVER, ENDANGERING ME AT NIGHT BY SHIFTING SUDDENLY INTO "STABILITRAK ERROR, LOW FUEL INPUT" MODE. I AM TERRIFIED THAT MY GMC DEALER WILL CHARGE ME MORE MONEY TO PRETEND-FIX THIS PROBLEM, AS THEY HAVE ME COMING IN FOR $400-$1,100 REPAIRS EVERY OTHER MONTH NOW SINCE THEY WANT TO SELL ME A NEW CAR. *TR

NO PREVIOUS SYMPTOMS. COULD NOT GET THE VEHICLE TO GO IN REVERSE. GOT TOWED TO THE DEALER. DIAGNOSIS - WAVE PLATE FRACTURE. FOUND MANY MANY 2007 GMC ACADIA'S HAD THIS PROBLEM, THERE SHOULD HAVE BEEN A RECALL. THIS HAPPENED 1 YEAR AFTER THE WARRANTY EXPIRED, BUT ONLY 74419 MILES, AND NEVER DRIVEN IN EXTREME CONDITIONS AND NEVER TOWED. *TR

NO RECALL FOR DEFECTIVE TRANSMISSIONS? BOUGHT 2007 ACADIAR USED, 2600 MILES /FELT TRANSMISSION PROBLEMS EARLY ON. VERY NOTICEABLE JERK AT 40MPH. IN AND OUT OF DEALERSHIP SINCE. LAST FEW MONTHS CAR HAS BEEN IN TO DEALER FREQUENTLY RE CAR BUCKING AT STOP LIGHTS REALLY ROUGH THOUGHT ENGINE GOING TO DIE. EVERY TIME NOTHING SHOWED IN CODES, EMERGENCY TRIP TO DOCTOR/HEAVY TRAFFIC MAIN ARTERY/CAN'T GET OVER 20MPH/ENGINE SCREAMING/ MAKE IT TO DR. (OMG) TOWED TO DEALERSHIP. TRANSMISSION GONE. I COULD HAVE HAD A SERIOUS ACCIDENT. FINALLY HEARD SOMETHING ABOUT A WAVE PLATE. FOR 5 YRS I'VE SAID SOMETHING WRONG. NO ONE SAID THESE WERE CONSTANT PROBLEMS WITH ACADIAS. THEY ISSUED RECALLS FOR A LEAK IN THE SUN ROOF. NO RECALL FOR DEFECTIVE TRANSMISSIONS? KNOWN DEFECTIVE WAVE PLATES? I HAVE EXTENDED WARRANTY, BUT MANY DON'T. WARRANTY OR NOT, THIS SAFETY HAZARD SHOULD BE FIXED BY GMC AT THEIR EXPENSE. A RECALL IS MANDATED. JUST ASK THE OWNERS. . . *TR

I WAS DRIVING MY CAR WHEN ALL OF A SUDDEN IT WOULDN'T ACCELERATE ABOVE (20MPH?). I WAS FORCED TO PARK IT AT AN APARTMENT COMPLEX AND GET IT TOWED TO THE DEALER. NOW LESS THAN 6 MONTHS AFTER PAYING OUT OF POCKET FOR THAT REPAIR, I AM HAVING THE SAME PROBLEM. *TR

STARTED SHIFTING WEIRD, THEN RPM'S WOULD SPIKE AS CAR WAS SHIFTING. CAR THEN WOULD NOT GO INTO ANY GEAR AND LEFT STRANDED ON SIDE OF ROAD. HAD TO HAVE VEHICLE TOWED TO DEALERSHIP WHERE IT WAS FOUND TO HAVE A BROKEN WAVE PLATE, DAMAGING NUMEROUS GEARS AND TORQUE CONVERTER. PRESSURE CONTROL MODULE WHICH IS PART OF THE VALVE BODY WAS BAD. HAD TO REPLACE ENTIRE TRANSMISSION, ALL SEALS, GASKETS. ALSO FOUND OUT WHEN REPLACING THAT THE THERMOSTAT HOUSING WAS LEAKING COOLANT, SO HAD TO HAVE THAT REPLACED AT SAME TIME. THIS AT A COST TO US OF OVER $3500.00. HAVE READ ONLINE THAT THIS IS A VERY COMMON ISSUE WITH THIS VEHICLE. WE WERE 7 MONTHS OUT OF OUR 5 YEAR/100,000 MILE WARRANTY AND GM WOULD NOT HELP IN THE LEAST. *TR

I HAVE OWNED THIS CAR FOR ABOUT A YEAR AND SINCE I HAVE OWNED IT HAVE HAD NOTHING BUT PROBLEMS. FIRST THE STRUTS WERE BLOWN, THE DASH LIGHTS WOULD GO FROM BRIGHT TO DIM, THE STEERING WHEEL MADE A CLICKING NOISE, THE WINDOWS LEAK...THIS CAR ONLY HAS 41,000 MILES I MEAN COME ON! NOW THE TRANSMISSION HAS COMPLETELY FAILED AND AFTER READING OTHER WEBSITES IT SOUNDS LIKE I WILL BE PAYING $4,000 DOLLARS. I AM A NEW MOM AND HAVE 3 STEP KIDS. I CAN'T FEEL SAFE IN MY CAR BECAUSE I'M WORRIED ABOUT IT BREAKING DOWN CONSTANTLY. NOW I HAVE TO DUMP ALL THIS MONEY THAT I DON'T HAVE INTO IT. I REALLY JUST WANT TO CUT MY LOSSES, BUT IS THAT REALLY THE BEST THING TO DO? I'M STUCK WITH THIS JUNKER CAR AND I COULDN'T FEEL MORE SORRY FOR ALL THESE OTHER PEOPLE HAVING THE SAME ISSUES.

3 MONTHS PAST THE 5 YEAR 100K WARRANTY WITH ONLY 55000 MILES ON THE CAR AND BOTH THE WATER PUMP AND TRANSMISSION WENT OUT. GM PAID FOR HALF OF THE COSTS STILL 1253.05 OUT OF POCKET WHEN IT SHOULD ALL HAVE BEEN COVERED. THIS IS A CONSISTENT PROBLEM WITH THE ACADIA AND GM KNOWS IT BUT REFUSES TO STEP UP. THE DAY THE TRANSMISSION WENT OUT WE ALMOST GOT THROWN THROUGH THE WINDSHIELD DEFINITELY A SAFETY ISSUE. *TR

Mileage: 55,000

PRIOR TO HAVING THE TRANSMISSION BREAK DOWN THE VEHICLE HAD BEEN SHIFTING HARD FROM 2ND GEAR TO 3RD GEAR. STARTING UP A SMALL GRADE FROM A STAND STILL THE TRANSMISSION SUDDENLY BEGAN SLIPPING AT ABOUT 20MPH. THE VEHICLE WOULD NOT SHIFT AND THE ENGINE LIGHT CAME ON. I WAS ONLY ABOUT 1 MILE FROM HOME SO I DROVE IT HOME AT ABOUT 25MPH. AT HOME I PUT IT IN REVERSE AND IT WOULD NOT GO INTO REVERSE. TOOK IT TO A TRANSMISSION SHOP THE NEXT DAY, THEY CALLED ME BACK LATER THAT DAY AND TOLD ME IT NEEDED A NEW TRANSMISSION. THEY ARE DOING THE JOB FOR $3200. *TR

I BOUGHT THIS VEHICLE JUNE 2012. I STARTED HAVING TRANSMISSION PROBLEMS LAST WEEK. THE TRANSMISSION WOULD STICK WHEN STEPPING ON THE GAS OR WHEN GOING IN REVERSE INTO MY GARAGE. I FOUND OVER 200 COMPLAINTS ABOUT THE TRANSMISSION. THIS SHOULD BE A RECALL ITEM. I WAS DRIVING ON THE HIGHWAY TRYING TO GET UP A HILL WHEN THE CAR STARTED TO DO THIS. I LUCKILY WAS NOT FAR FROM MY EXIT AND MADE IT TO A GAS STATION WHEN THE CAR JUST STOPPED. *TR

Mileage: 61,000

THE VEHICLE WOULD NOT SHIFT OUT OF 2ND GEAR GOING DOWN THE HIGHWAY. THE CHECK ENGINE LIGHT CAME ON, AND THERE ARE NOW FOUR CODES ALL FOR INTERNAL TRANSMISSION ISSUES. THE CAR IS 4 MONTHS PAST THE 5 YEAR WARRANTY, BUT ONLY 64000 MILES. THIS IS A HUGE SAFETY ISSUE. IF THIS TRANSMISSION FAILS WHILE ON AN INTERSTATE HIGHWAY, AND IT WILL NOT GO OVER 20 MPH, THE RESULTS COULD BE DEADLY. BY RESEARCHING THIS ISSUE I HAVE FOUND A CONSIDERABLE AMOUNT OF COMPLAINTS ABOUT 2007 GMC ACADIAS BETWEEN 50000 AND 80000 MILES HAVING TRANSMISSION FAILURES, BUT YET NO RECALLS. THIS IS AN ISSUE THAT GMC IS WELL AWARE OF, THROUGH THEIR OWN ADMISSIONS. WHY IS THERE SUCH A DELAY WAITING FOR A RECALL? ARE ALL OF THE COMPLAINTS GOING TO HAVE TO WAIT FOR A FATALITY BEFORE GMC ADMITS THERE NEEDS TO BE CORRECTIVE ACTIONS? *TR

Mileage: 64,000

THE CAR HAS HAD ELECTRICAL AND ENGINE PROBLEMS SINCE WE PURCHASED IT DUE TO WATER LEAKS FROM A FLAWED SUNROOF DESIGN. EVEN AFTER A RECALL TO FIX THE SUNROOF TO PREVENT WATER LEAKS; IT CONTINUES TO LEAK AND DAMAGE ELECTRICAL AND ENGINE SYSTEMS. THIS IS AN ONGOING PROBLEM AND IS A WIDESPREAD CONCERN FOR THE 2007-2008 GMC ACADIAS. I WOULD LIKE SOMEONE TO INVESTIGATE THIS PROBLEM. I BELIEVE IT IS A SAFETY CONCERN BECAUSE THE LEAKS OCCUR IN THE AREA WHERE THERE ARE AIRBAGS. I THINK THERE IS A STRUCTURAL DEFECT THAT MAY NOT BE ABLE TO BE REPAIRED AND IT PRESENTS A SAFETY HAZARD FOR ALL WHO DRIVE THESE VEHICLES. PLEASE INVESTIGATE THIS PROBLEM. DO NOT LET GMC SWEEP THIS UNDER THE RUG! *TR

Mileage: 15,499

WHILE TRAVELING AT 45 MPH, AND WITH NO WARNING (WEIRD SHIFTING, ETC) THE TRANSMISSION COMPLETELY FAILED. AFTER BEING LIED TO BY THE DEALERSHIP AND GM, I DID MY OWN RESEARCH AND FOUND THAT THIS IS A COMMON PROBLEM WITH THIS MODEL YEAR, SO MUCH SO THAT GM HAS CREATED A SPECIAL PROGRAM TO FUND PART OF THE REPAIR IF THE VEHICLE IS OUT OF WARRANTY. (WAVE PLATE FAILURE IN THE TRANSMISSION). THIS VEHICLE SHOULD BE RECALLED WITH A MANDATORY REPLACEMENT OF THE WAVE PLATE. *TR

Mileage: 71,411

MY 2007 GMC ACADIA'S FIRST STARTED HAVING TRANSMISSION PROBLEMS IN DECEMBER OF 2012. THE VEHICLE STARTED HAVING ISSUES WHILE TRYING TO MERGE ONTO THE HIGHWAY OR DEPRESSING THE GAS PEDAL FOR A PASSING AND/OR MERGING PURPOSES, THIS WOULD SOMEHOW REVERT INTO A NEUTRAL POSITION, HAVING THE RPMS REV UP AND NO FORWARD MOTION , UNTIL IT'S SORT OF CAUGHT UP ITSELF BY BACKING OFF ON THE ACCELERATOR. THE OTHER ISSUE INVOLVED PUTTING THE AUTOMOBILE INTO REVERSE ,NOT ONLY AT TIMES IT WOULDN'T GO INTO REVERSE BUT INSTEAD WOULD REVERT TO A NEUTRAL POSITION, UNTIL YOU STARTED ALL OVER AGAIN WITH THE PROCESS OF PUTTING IT BACK INTO PARK AND THEN BACK INTO REVERSE. NEVER WAS THERE A LIGHT NOR A WARNING BY THE CARS SENSORS OR ANY OTHER SYMPTOMS THAT WOULD GIVE AN OWNER A WARNING THAT THERE WOULD BE A PROBLEM COMING SOON. IN ANY EVENT, AFTER HAVING THE SYMPTOMS DESCRIBED ABOVE THE CAR SOMEHOW DROPPED INTO FIRST GEAR AND CANNOT SHIFT FROM THAT POSITION AND FINALLY, THE TRANSMISSION LIGHT CAME ON. AT THE MOMENT, I AM IN THE PROCESS OF FILING A COMPLAINT WITH GM AND AT THE ADVICE OF THE GM REPRESENTATIVE, THEY ADVISE ME TO HAVE THE DEALERSHIP LOOK INTO THE SITUATION. IN MY OPINION, THIS IS A VERY DANGEROUS SITUATION. SEEING ALL THE SAME COMPLAINTS ON THE INTERNET LEADS ME TO BELIEVE THAT THERE SHOULD BE A FURTHER DISCUSSION ON THE TRANSMISSION OF THE 2007 GMC ACADIA. THANK YOU *TR

WE WERE LEAVING MY SONS BASKETBALL GAME TONIGHT AND WHEN WE WENT TO ENTER THE INTERSTATE THE TACHOMETER WENT TO 5000 RPM'S AND THE VEHICLE WAS NOT MOVING.

TOOK THE CAR TO THE DEALER TO HAVE IT CHECKED OUT BECAUSE I THOUGH IT WAS THE TRANSMISSION. THEY THOUGHT THE TIRES NEEDED TO BE ROTATED AND BALANCED, WHICH DID NOT FIX THE PROBLEM. BY 106,000 MILES IT WAS SO BAD THAT THE VEHICLE COULD NOT BE DRIVEN SAFELY. THIS TIME THE DEALERSHIP SAID IT WAS THE MOTOR MOUNTS, WHICH DID NOT FIX THE PROBLEM. I HAD THEM KEEP THE CAR UNTIL THEY FOUND THE PROBLEM. AFTER 2 WEEKS THEY DETERMINED THAT IT WAS THE TRANSMISSION! AFTER THE TRANSMISSION WAS REPLACED THE VEHICLE DRIVES GREAT. I HAVE READ HUNDREDS OF COMPLAINTS ON THE ACADIA TRANSMISSION AND THERE ARE LIKELY TENS OF THOUSANDS OF CASES JUST LIKE MINE. THERE SHOULD BE A RECALL FOR THE TRANSMISSION ON THIS VEHICLE. *TR

9/27 AS I WAS DRIVING IN A RESIDENTIAL NEIGHBORHOOD TO TAKE MY DAUGHTER TO SCHOOL I WAS APPROACHING A GREEN LIGHT AT A FOUR WAY AND STARTED TO ACCELERATE TO 35 MPH FROM A COMPLETE STOP TO CROSS FOUR LANES OF TRAFFIC. THE VEHICLE REACHED 35 MPH AND ALTHOUGH THE SPEEDOMETER STATED 35MPH THE VEHICLE STOPPED MOVING AND STALLED AND STARTED MAKING A CHURNING NOISE COMING FROM THE ENGINE. AT THIS POINT MY FRONT END WAS IN TRAFFIC UNDER THE LIGHT THAT WAS NOW TURNING RED SO I HAD TO THINK QUICK AND PUT ON MY FLASHERS TO ALERT THE OTHER DRIVERS THAT I WAS HAVING DIFFICULTIES AS I COULDN'T GET THE TRUCK TO MOVE. WHEN I PRESSED THE GAS PEDAL THE ENGINE JUST ROARED BUT NO MOVEMENT. ONCE OTHER DRIVERS WERE ALERTED I HAD TO COAST BACKWARDS FROM THE INCLINE AT THE LIGHT AND MANEUVER ONTO THE SIDE OF THE ROAD. I TURNED THE TRUCK BACK ON AND IT CAME ON AND MIRACULOUSLY I WAS ABLE TO DRIVE IT 5FT OFF THE ROAD BEFORE IT STALLED AGAIN. I HAD TO BE TOWED TO A DEALER AS OF TODAY I WAS TOLD IT WAS THE TRANSMISSION BUT THE DEALER HAD TO CONTACT GMC TO REPORT ALL MAJOR ENGINE FAILURE BEFORE PROCEEDING WITH ANY WORK. LAST YEAR IN DEC. MY TRUCK STARTED MAKING WHINING NOISE AND I IMMEDIATELY TOOK IT TO THE DEALER TO FIND OUT THAT THE CAMSHAFT HAD WENT BAD AND SPIT METAL IN MY MOTOR CAUSING ME TO HAVE THE ENGINE REPLACED. BECAUSE I WAS THE SECOND OWNER OF THE VEHICLE GM DIDN'T WANT TO PAY FOR THE TOTAL BILL UNDER THE POWERTRAIN WARRANTY AND THE FACT THAT I WAS 3000 MILES OVER THE POWERTRAIN WARRANTY ITSELF. THEY DID PAY A THIRD OF A $5000 BILL AND I HAD TO PAY THE REST ONLY TO HAVE THEM PLACE A RECALL ON THE CAMSHAFT AND TO REIMBURSE ME HALF OF WHAT I PAID. THIS SITUATION WITH THE TRANSMISSION REMINDS ME OF THE ROLLOVER WITH THE FIRESTONE TIRE FORD HAD YEARS BACK BUT THE DIFFERENCE IS THAT FORD AND FIRESTONE TOOK RESPONSIBILITY. PLEASE MAKE GM RESPONSIBLE BEFORE SOMEONE IS KILLED. *TR

BASICALLY BOTTOM LINE IS THIS IS THE 4TH MAJOR THING I'VE HAD MY ACADIA IN THE SHOP FOR. THIS REPAIR OF A REBUILT TRANSMISSION IS COSTING ME 3500.00 OUT OF MY POCKET. SUPPOSEDLY THE GM CUSTOMER REP DOES NOT THINK THERE IS ANYTHING THEY CAN DO FOR ME BECAUSE MY CAR IS 5 YEARS OLD AND 131000 MILES.. THAT IS JUST BS!!!!! I SPENT 40,000.00 ON THIS CAR TO DRIVE IT LONGER THAN THIS AND FOR ALL THE THINGS TO START NICKEL AND DIMMING ME IS RIDICULOUS. THE MECHANIC AT THE GM CERTIFIED GARAGE TOLD ME THAT GM USED A PRT IN THE TRANSMISSION ON THE 07-10 MODELS OF THE ACADIA THAT COST THEM 1.69 AND THAT THEY KNOW THEY SHOULD HAVE USED A PART THAT COST THEM 39.00, SO THIS IS THE PART THAT IS BREAKING IN THE TRANSMISSIONS AND MAKING THEM JUNK AND HAVING TO BE REBUILT OR NEW ONES PUT IT.. GM DIDN'T WANT TO RECALL THE 07-10 MODELS BECAUSE IT WOULD HAVE AFFECTED MILLIONS OF CARS, SO THEY ARE JUST LETTING THE OWNERS SUFFER FOR THEIR STUPIDITY AND LACK OF RESPONSIBILITY. MY BIGGEST COMPLAINT AFTER THE MONEY IS THE FACT THE MY CHILD WAS DRIVING MY VEHICLE WHEN THIS HAPPENED, HE WAS PANICKED AS HE COULD NOT GO OVER 30MPH ON A VERY BUSY ROAD AND THE VEHICLE STARTED TO SHUT DOWN ON HIM!! HE IS VERY LUCKY THE VEHICLE MADE IT TO A SAFE PLACE AND HE WAS NOT REAR ENDED AS THE CAR JUST STOPPED ON HIM!!! REALLY GM WHEN ARE YOU GOING TO RECALL THESE MODELS AND MAKE IT RIGHT FOR ALL OF US THAT HAVE TO ENCOUNTER SUCH A HIGH EXPENSE?? I REALLY CAN NOT AFFORD ANOTHER VEHICLE OR THE $3500.00 TO REPAIR THIS ONE, BUT THAT IS MY ONLY CHOICE!!!! *TR

I HAD TO HAVE ALL NEW TIMING CHAINS PUT ON 103,000 MILES, HAD TO HAVE MY SERVICE TIRE SENSOR FIXED AT 112,000 MILES, I HAVE DONE ALL THE RE-CALLS FOR THE SUN-ROOF LEAK, THE HEATED WINDSHIELD FLUID, AND WHATEVER ELSE HS BEEN RE-CALLED ON THIS VEHICLE!!! MY 17 YEAR OLD SON WAS DRIVING MY CAR IN HEAVY TRAFFIC ON A MAJOR HIGHWAY WHEN THE CAR JUST STOPPED AND THEN HE COULD ONLY GET IT TO GO 30 MPH. HE IS LUCKY HE WAS NOT REAR ENDED. I TOOK IT TO THE DEALER, IT WILL NOT GO OVER 30 MPH AND REVERSE. I SPOKE WITH THE HEAD MECHANIC AT THE GM GARAGE THAT IS PUTTING A NEW TRANSMISSION IN MY ACADIA AT THE COST OF 3400.00 TO ME, AND HE TOLD ME THAT ALL THE 2007-2010 ACADIA'S HAVE A PART IN THE TRANSMISSION THAT COST GM $1.69 INSTEAD OF USING THE PART THEY SHOULD HAVE USED THAT WOULD HAVE COST THEM $39.00. HE SAID GM KNOW THEY SHOULD HAVE RECALLED ALL THE 2070-2010 ACADIA'S BUT CHOSE NOT TOO BECAUSE IT WOULD HAVE BEEN MILLIONS OF VEHICLES INVOLVED, SO INSTEAD "THANK YOU GM" FOR SCREWING ALL OF US AND NOW WE HAVE TO PAY FOR YOUR MISTAKE AND CUT BACKS.... *TR

WHILE DRIVING, THE VEHICLE STARTED SKIPPING/CATCHING WHILE ACCELERATING AND THE TEMPERATURE GAUGE STARTED TO CREEP UP. I ENTERED A LEFT TURN LANE IN ORDER TO PULL OVER. WHEN TRAFFIC CLEARED I ATTEMPTED TO ACCELERATE TO MAKE IT INTO THE PARKING LOT. WARNING BELLS STARTED GOING OFF "SHUT OFF ENGINE" "SHUT OFF A/C" "ENGING OVERHEAT" AND THE TRUCK SHUT OFF. I HAD PICKED UP ENOUGH MOMENTUM AS I HAD BEGUN MY TURN BUT IT WAS STILL LITERALLY A COAST INTO THE PARKING LOT, NARROWLY AVOIDING A T-BONE SITUATION WITH AN ONCOMING MINI VAN. IT WAS SO CLOSE THE MINI-VAN LAID ON THE HORN AND SLAMMED ON HER BRAKES. I COASTED INTO THE PARKING LOT BUT WAS UNABLE TO MAKE IT INTO A SPOT. I TOOK OUT MY KEYS AND OPENED MY DOOR TO GET OUT. THE ALARMS CONTINUED EVEN WITHOUT KEYS IN IT. THERE WAS ANTIFREEZE POURING OUT FROM UNDERNEATH THE VEHICLE. I HAD TO TURN ON AND OFF THE CAR NO LESS THAN THREE TIMES TO STOP THE WARNING BELLS. I CALLED A LOCAL SHOP AND HAD IT TOWED. THEY REPLACED THE WATER PUMP AND A/C BELT. GOT MY VEHICLE BACK TWO DAYS LATER. DROVE TO WORK IN THE MORNING WITH NO ISSUES, HOWEVER COMING HOME IT STARTED TO CATCH/SKIP AGAIN. (I LIVE ONLY 5 MILES AWAY FROM WORK). I HAD MY HUSBAND DRIVE IT BACK UP TO THE SHOP TO HAVE IT LOOKED AT. WHEN HE GOT INTO IT HE WAS UNABLE TO REVERSE IT; REVERSE JUST SIMPLY STOPPED WORKING. HE HAD TO TURN AROUND IN OUR YARD - ON THE WAY TO THE SHOP (6 MILES AWAY) THE VEHICLE WOULD NOT GO OVER 30 MPH AND AGAIN SHUT OFF ON HIM WHILE TRYING TO TURN INTO THE AUTO SHOP. THE DIAGNOSIS NOW IS THAT IT NEEDS A NEW TRANSMISSION. UPON FURTHER ONLINE RESEARCH I HAVE FOUND THOUSANDS OF OTHER OWNERS OF THE SAME MODEL/MAKE AND YEAR WITH THE EXACT SAME ISSUES OCCURRING ROUGHLY AROUND THE SAME MILEAGE/TIME FRAME. THERE ARE THREE OTHER ACADIAS ALONE AT OUR LOCAL GM DEALERSHIP WAITING TO BE FIXED WITH THE EXACT SAME ISSUES. *TR

ALSO, THE ABS LIGHT AND STABILTRAK LIGHTS ILLUMINATED.

I PURCHASED A BRAND NEW 2007 GMC ACADIA IN NOV. OF 2007. SINCE NEW IT HAS HAD A STEERING ISSUE THAT CAN NOT BE FIXED. THE RACK AND PINION HAS BEEN REPLACED AND THE VEHICLE HAS BURNED UP NUMEROUS POWERSTEERING PUMPS. THE STEERING, WHILE IN A CURVE, WILL LOCK UP AND THEN RELEASE THROWING THE VEHICLE IN THE DIRECTION THE WHEEL IS TURNED. IT HAS THROWN THE VEHICLE INTO THE OTHER LANE OF ON COMING TRAFFIC AS WELL AS THROWING THE VEHICLE OF THE ROAD INTO A FENCE. EACH TIME THE DEALERSHIP HAS PICKED THE VEHICLE UP REPLACED THE STEERING PUMPS BUT THE PROBLEM STILL REMAINS. THE VEHICLE CURRENTLY HAS 47,000 MILES ON IT. THE TRANSMISSION LOCKED UP AND THE SHIFTING COMPONENTS WERE REPLACED, THEN THE TRANSMISSION LOCKED UP AND WAS REPLACED. THE STEERING ISSUE IS ARE MAIN CONCERN. IT WAS TAKEN IN ON 9/28/10 AND RECEIVED NEW TRANSMISSION AND POWERSTEERING PUMP. WE RECEIVED THE VEHICLE ON 10/25/2010. ON, 10/28/10 THE VEHICLE STEERING LOCKED UP AGAIN THROWING MY WIFE OFF THE ROAD INTO A FENCE. THERE IS NO WAY THAT GM HAS PUT THREE BAD POWER STEERING PUMPS ON THE VEHICLE. THE VEHICLE HAS A MORE SERIOUS PROBLEM THAT IS BINDING THE STEERING CAUSING THE PUMPS TO BURN UP. THE SAME PROBLEM HAS MADE THE VEHICLE UNSAFE TO DRIVE DUE TO THE DANGER OF IT LOCKING UP AND THROWING THE VEHICLE INTO ON COMING TRAFFIC. I HAVE ALL SERVICE RECORDS REPORTING THIS ISSUE. I WILL NOT ALLOW MY BACK IN THIS VEHICLE AND I AM NOT COMFORTABLE TRADING IT IN FOR ANOTHER FAMILY TO BE KILLED IN IT. I COULD NOT LIVE WITH THAT. GM WILL DOING NOTHING ABOUT AS THEY HAVE BEEN CONTACTED. PLEASE HELP ME GET A REPLACEMENT FOR THIS VEHICLE (SAME YEAR MODEL TYPE AND EQUALLY EQUIPPED) AND GET THIS VEHICLE OFF THE ROAD. I COULD TRADE IT IN AS GM WANTS ME TOO AND THEY WILL GIVE ME $1600 OFF THE TRADE. BUT COULD NOT SLEEP AT NIGHT KNOWING I PUT SOMEONE ELSE AND THEIR FAMILIES IN DANGER WITH THIS VEHICLE.

DRIVING MY 2007 GMC ACADIA. WENT TO PASS A SLOWER VEHICLE, PRESSED ON THE ACCELERATOR TO PASS AND THE TRANSMISSION WENT HAYWIRE AND THE ACCELERATOR STUCK. I HAD TO PUT THE CAR IN NEUTRAL TO GET IT STOPPED. THE RPMS WERE IN THE 4000S. THEN THE ACCELERATION WOULD STOP AND START AGAIN OVER TO 4000. LUCKILY WHEN I PASSED THE VEHICLE THERE WERE NO CARS IN FRONT OF ME OR I WOULD HAVE HAD A MAJOR ACCIDENT WITH THE ACCELERATION OUT OF CONTROL. I TOOK IT TO THE DEALER AND THEY TOLD ME THAT TWO OF THE TIMING CHAINS WERE VERY WORN AND THERE WAS AN ISSUE WITH THE CLUTCH PRESSURE CONTROL WITH HARSH SHIFTS IN DRIVE RANGE 3RD AND/OR 5TH GEAR. THIS IS THE SECOND TIME I HAVE HAD PROBLEMS WITH THIS ISSUE. THE FIRST TIME THE GMC DEALER 'FLASHED' (REPROGRAMMED) THE TRANSMISSION, EVEN THOUGH IT WAS NOT ACTING UP WHEN THE CAR WAS TAKEN INTO THE SHOP. IF THIS ISSUE IS NOT ADDRESSED "PROPERLY", I BELIEVE SOMEONE SOMEWHERE WILL BE INJURED OR KILLED. THE CONDITION MY VEHICLE EXHIBITED LEAVES ME WITH A VERY UNEASY FEELING. *TR

MY 2007 ACADIA WOULD DRIVE ABOVE 50KM IT FINALLY BROKE DOWN AND WOULDN'T MOVE. WE HAD TO GET A FLATBED TRUCK TO TAKE THE CAR IN TO GM AND FOUND OUT IT WAS THE SWAY BAR THAT WAS BROKE AS WELL AS THE CRANKSHAFT SENSOR AND JUST A MONTH BEFORE THIS WE HAD ISSUES WITH THE STEERING WHEEL THAT HAD TO BE FIXED. THERE HAS BEEN SO MANY THINGS WRONG WITH CAR ITS UNBELIEVABLE I WENT TO TRADE IT IN AND FINDING OUT THAT WE PAID 45,000 FOR IT BRAND NEW NOW ITS ONLY $20,000 AT THE MAX WE CAN GET FOR OUR AWD ACADIA WITH MOST OF THE BELLS AND WHISTLES. NOW IT IS LACKING POWER IN ACCELERATION AGAIN MERGING ON HIGHWAYS OR PULLING OUT IN TRAFFIC THE CAR LULLS OUT AND SOUNDS LIKE ITS STUCK IN NEUTRAL AND IT FINALLY KICKS IN AND GOES VERY DANGEROUS I COULD OF BEEN REAR ENDED THE OTHER DAY BECAUSE OF THIS IT WAS A CLOSE CALL. *TR

DRIVING MY 2007 GMC ACADIA. CAME UPON A BUSY STATE HIGHWAY. AFTER COMING TO A STOP, I SAW AN OPENING AND PRESSED ON THE ACCELERATOR TO CROSS THE 4 LANE ROAD. WHEN I PRESSED THE ACCELERATOR, THE CAR JUST STARTED TO CREEP OUT INTO TRAFFIC. THE ENGINE RPM'S INCREASED, BUT THE CAR WAS MOVING AT WALKING SPEED. IT WAS OBVIOUS THAT THE TRANSMISSION HAD NOT SHIFTED BACK INTO 1ST GEAR. I TRIED TO MANUALLY SHIFT INTO LOW, BUT IT DID NOT RESPOND. I FINALLY WAS ABLE TO GET IT GOING FAST ENOUGH TO HAVE IT PICK UP SOME SPEED TO GET ACROSS THE LANES OF TRAFFIC. ON THE WAY HOME, EVERY TIME I CAME TO A STOP, THE CAR ACTED THE SAME WAY UPON ACCELERATION. THE ONLY WAY I WAS ABLE TO GET THE CAR TO GO BACK INTO 1ST GEAR WAS TO SHUT THE CAR OFF AND RESTART IT. EVEN DOING THAT, IT ONLY LASTED UNTIL THE NEXT TIME I STOPPED. AFTER LETTING THE CAR SIT OVER NIGHT, IT PERFORMED FINE THE NEXT DAY. THIS IS THE SECOND TIME I HAVE HAD PROBLEMS WITH THIS ISSUE. THE FIRST TIME THE GMC DEALER 'FLASHED' (REPROGRAMMED) THE TRANSMISSION, EVEN THOUGH IT WAS NOT ACTING UP WHEN THE CAR WAS TAKEN INTO THE SHOP. I SPOKE WITH A CAR DEALER AT THE SHOP, AND HE OWNED THE SAME VEHICLE. HIS TRANSMISSION HAS BEEN 'REFLASHED' 6 OR 7 TIMES FOR THE SAME ISSUE. IF THIS ISSUE IS NOT ADDRESSED "PROPERLY", I BELIEVE SOMEONE SOMEWHERE WILL BE INJURED OR KILLED. THE CONDITION MY VEHICLE EXHIBITED LEAVES ME WITH A VERY UNEASY FEELING (I.E. WHEN I PRESS THE ACCELERATOR, I EXPECT THE CAR TO MOVE). IF REFLASHING THE TRANSMISSION (1, 2, 3, 4...7 TIMES) DOES NOT FIX THE PROBLEM, THEN MAYBE SOMETHING DIFFERENT NEEDS TO BE DONE. *TR

2007 GMC ACADIA: WHEN STEPPING ON THE GAS TO ACCELERATE OR PASS THE TRANSMISSION DOES NOT IMMEDIATELY RESPOND (SEVERAL SECONDS DELAY) WHICH CAUSES YOU TO CONTINUE PUSHING DOWN THE GAS PEDDLE UNTIL IT ENGAGES WHICH USUALLY CAUSES A 10,000 RPM SURGE. MAKES IT VERY SCARY WHEN PASSING AND THE ACCELERATION COULD CAUSE ISSUES WHEN THE ROAD IS WET OR ICY. GMC STATES THAT THE ISSUE IS WELL DOCUMENTED AND "NORMAL" FOR THE VEHICLE. AFTER THREE ATTEMPTS AND DISCUSSION WITH THE SERVICE MANAGER WHO ALSO DRIVES THIS SAME MODEL AND STATES HOW SCARY IT IS WHEN TRYING TO PASS IN HIS ACADIA I AM LOOKING FOR SOMEONE TO FORCE GMC TO FIX THE TRANSMISSION BEFORE SOMEONE GETS KILLED. ACCORDING TO THE DEALERSHIP THIS IS A VERY COMMON COMPLAINT FROM CUSTOMERS AND NOT GETTING ATTENTION FROM THE MANUFACTURER. BASICALLY GMC STATES " HERE IS THE FIX AND NOW YOU LIVE WITH IT!" THIS IS AN ACTUAL QUOTE. I HAVE ALSO SPENT TIME DISCUSSION WITH THE SO CALLED GMC CUSTOMER SERVICE REP. WHO BASICALLY CAN'T/WON'T GET ME IN CONTACT WITH ANYONE WHO CAN RESOLVE.(TOMEKA MONROE 1-866-790-5600-EX 31353) PLEASE HELP, BRAD BARGER *TR

2007 GMC ACADIA WITH SEVERAL SERIOUS SAFETY ISSUES. SHE STATES THAT THE VEHICLE HAS HAD THESE PROBLEMS: A LARGE PUDDLE OF OIL UNDER THE VEHICLE, WINDSHIELD WIPERS STOPPED WORKING, BATTERY DIED AND SIDE CURTAIN AIRBAGS DEPLOYED WHILE DRIVING. *KB THE DEALER TOLD THE CONSUMER THE FRONT SHAFT SEAL NEEDED TO BE REPLACED TO CORRECT THE LEAK FROM THE TRANSMISSION. THEY ALSO STATED THERE WAS A DRAIN ON THE SYSTEM THAT CAUSED THE BATTERY TO FAIL. THE CONSUMER TOOK THE VEHICLE BACK TO THE DEALER WHERE THEY UPGRADED THE TRANSMISSION, WHICH HAD TO BE DONE TWICE. THE POWER STEERING MADE A LOUD NOISE, THE CONSUMER STATED IT SOUNDED AS IF THE PUMP WAS ABOUT SEIZE AND THEN THE STEERING BECOMES HARD. THE VEHICLE ROLLED BACKWARDS WHILE IN DRIVE ON A SLIGHT INCLINE.*JB UPDATED 04/10/08

SEVERAL ISSUES WITH THIS NEW 2007 GMC ACADIA. MOST PREVALENT IS THE FAILURE OF THE GAS GAUGE NOT READING THE GAS READING CORRECTLY. 1ST TIME NOTICED AND TAKEN FOR SERVICE WAS 3 MO. OLD. THE GAS GAUGE READS (E) WHEN I'VE JUST FILLED UP THE TANK. DEALER REPLACED 02 SENSORS. 1 MO LATER EXPERIENCE SAME ISSUE. GAS GAUGE READS (E) EVEN WHEN TANK IS FULL. TAKEN BACK TO DEALER AND THIS TIME REPLACE (2) O2 SENSORS AND THE "SENDING UNIT". 2 DAYS LATER, WITH THE GAS GAUGE READING AT HALF FULL, THE CAR LUNGES FORWARD INTO ANOTHER GEAR ON FREEWAY IN TRAFFIC, AND STALLS. CANNOT TURN CAR ON - ALL WARNING LIGHTS ON. TOWED TO DEALER. NOW STATES THAT I NEED A WHOLE NEW GAS TANK BECAUSE THE "BAFFLE" IS BROKEN? STILL AT THE DEALER AND IS UNRESOLVED. THIS CAR IS UNSAFE. PREVIOUS ISSUES: CAR LEAKS AT THE SUNROOF. NOT FIXED YET LUMBAR SUPPORT BROKEN - SOMEWHAT FIXED BUT STILL NOT LIKE THE NEW ONES ON THE LOT. LUMBAR HANDLE FELL OFF - REPLACED BACKUP SENSORS FELL OFF OF BUMPER - REPLACED SEAT TRACKS JERK - REPLACED BOTH DRIVER AND PASS. STILL NOT SMOOTH BUT DEALER SAYS THAT'S THE BEST THEY CAN DO. *TR

NOTICED A SUDDEN SHAKING IN THE CAR WHEN DRIVING MORE THAN 25MPH. FELT THE CAR WAS UNSAFE TO DRIVE, SO LEFT IT AT A LOCAL TIRE AND AUTO SHOP FOR INSPECTION THE NEXT MORNING. THE TECHNICIAN CALLED TO INFORM US THAT THERE SHOULD BE 6 BOLTS THAT ATTACH THE DRIVESHAFT TO THE FRONT DIFFERENTIAL. THE CAR ONLY HAD 3 OF THE 6 BOLTS LEFT AND OF THOSE 1 WAS BENT. THEY WERE ALSO ALL LOOSE. HE SUSPECTED THAT THEY WERE NOT TIGHTENED CORRECTLY AT THE FACTORY. THE CAR WAS TOWED TO THE NEAREST DEALERSHIP FOR INSPECTION AND REPAIR. THIS CAR WAS PURCHASED IN 3/07 AND CURRENTLY HAS 12,000 MILES. *TR

I LEASED A 2007 ACADIA ON 5-24-07 AND SHORTLY AFTER TAKING DELIVERY I FELT THERE WAS SOMETHING WRONG WITH THE TRANSMISSION AND THE WAY IT SHIFTED, I NOTIFIED THE DEALERSHIP ABOUT THE PROBLEM AND TOOK IT IN FOR REPAIR. THEY TOLD ME THEY COULDN'T GET THE PROBLEM TO REPEAT AND FELT THERE WAS NOTHING WRONG. ON 6-14-07 I TOOK A TRIP TO FLORIDA FROM MICHIGAN AND GOT 11 MILES INTO GEORGIA AND THE TRANSMISSION DECIDED TO SHIFT INTO 1ST GEAR GOING 70 MPH. I MANAGED TO GET OFF THE ROAD AND WAS WONDERING WHAT WENT WRONG. I PUSHED THE ONSTAR BUTTON AND THEY GOT ME TO A DEALERSHIP (NEWTON GMC IN TENNESSEE), THEY DONE A QUICK COMPUTER CHECK FOR ERROR CODES AND FOUND MANY CODES THAT THEY DIDN'T KNOW WHAT THEY WERE BUT THEY SAID IT WAS RELATED TO THE TRANSMISSION. I LEFT THE ACADIA WITH THEM AND FINISHED MY TRIP TO FLORIDA IN A FORD PICKUP. AFTER 2 WEEKS THE DEALERSHIP GOT THE OK FROM GM TO REPLACE THE TRANSMISSION. I AM STILL HAVING PROBLEMS WITH THE NEW TRANSMISSION SHIFTING CORRECTLY. AS OF 9-17-07 THERE IS A NEW SOFTWARE UPDATE THE DEALERSHIPS WILL HAVE TO CORRECT THE SHIFTING PROBLEMS FOR 2007 MODELS, THE 2008 MODELS ALREADY HAVE THE NEW SOFTWARE IN THEM WHEN THEY LEAVE THE ASSEMBLY PLANT. THIS PROBLEM MAY BE ON THE 2007 SATURN OUTLOOK BECAUSE THEY HAVE THE SAME TRANSMISSION. *TR

I HAVE HAD MY TRANSMISSION WORKED ON ALREADY ON MY 2007 GMC ACADIA THE SPEED CONTROL IN THE TRANSMISSION HAS BEEN REPLACED BUT I STILL HAVE A PROBLEM WITH THE PERFORMANCE OF THE CAR. IT IS AN ALL WHEEL DRIVE WITH AN AUTOMATIC. IT WILL NOT HOLD ON A HILL AND SEARCHES FOR A GEAR OR CHANCES SEVERAL TIMES WHEN IT COMES TO ANY KIND OF INCLINE EVEN AT 70 MPH.I WAS GETTING 15 MILES TO THE GALLON BEFORE THE NEW SPEED CONTROL NOW I GET 13. I HAVE SPOKEN TO MY DEALER SEVERAL TIMES AND HE SAYS TO WAIT AND SOON THERE SHOULD BE A UPDATE IN THE SOFTWARE TO ADDRESS THIS PROBLEM I AM WILLING TO WAIT BUT WANT IT ON RECORD THAT THE TRANSMISSION HAS PROBLEMS. THIS IS A NEW DESIGN AND IS VERY ROUGH RIDING. MY CAR HAS ONLY 5000 MILES ON IT AND I HAVE BEEN THERE 4 TIMES.

TL*THE CONTACT OWNS A 2007 GMC ACADIA. WHILE DRIVING 25 MPH THE VEHICLE WOULD VIBRATE. THE CONTACT HEARD A LOUD BANG NOTICED PARTS FLY PAST THE WINDOW.

ON JULY 5TH 2007 MY FAMILY AND I WERE TRAVELING IN OUR RECENTLY PURCHASED 2007 GMC ACADIA WHILE ON VACATION IN FENWICK, DE. AND AS WE WERE TRAVELING THROUGH AN INTERSECTION OUR VEHICLE EXPERIENCE A MASSIVE FAILURE. THE FRONT PORTION OF THE DRIVE SHAFT, THE PORTION THAT EXTENDS FROM THE TRANSAXLE TO THE REAR AXLE, DROP FROM THE VEHICLE, AT SPEED, AND CAUSED THE VEHICLE TO LOOSE POWER WHILE AT SPEED IN TRAFFIC. REALIZING THE LOSS OF POWER, WE PULLED THE VEHICLE SAFELY TO THE SIDE OF THE ROADWAY TO INSPECT THE VEHICLE. UPON LOOKING UNDER THE VEHICLE, I OBSERVED THE DRIVE SHAFT HANGING, IN THE FORWARD POSITION, TO THE ROADWAY. I IMMEDIATELY CALLED "ON-STAR" WHO I FOUND TO BE EXTREMELY NON-RESPONSIVE OR HELPFUL TO OUR SITUATION. THE FOLLOWING DAY, THE TOW TRUCK FINALLY RESPONDED TO OUR CALL AND UPON OUR DIRECTION TOOK THE VEHICLE TO HERTRICK GMC FOR REPAIR. LATER THAT WEEK I WS INFORMED THAT THE "SAFETY RING" HAD FAILED AND THE REPLACEMENT PRT WAS ON INDEFINITE BACK ORDER. *TR
