What 300 owners told NHTSA about the 2012 GMC Acadia Denali

My air conditioning stopped working and the power steering line got so hot that it melted a pinhole in my AC line so all the freon would leak out. the power steering hose is so close that when it gets hot it melts the aluminum air conditioning line. The only way to fix it is to buy a aftermarket line and splice it together with the damaged a/c line. And the safety Hazzard is that if you're in hot car,you'll be more tempted to pull out in front of someone because you need to get some air. If you look at the setup you will see the engineer made a mistake, that's why they changed the design in later years,I think they should be responsible for making such a preventable mistake.

When the rear lift gate gets to the full open position, it immediately falls down causing a safety hazzard. Luckily no one was in the way when this happened. I haven't had it inspected yet and there are no warning lights or messages. It is available for inspection upon request.

A P0306 CODE APPEARED. I TOOK IT TO MY MECHANIC AND HE EXPRESSED THAT MY ENGINE WAS 'POROUS'. WHEN I START MY ENGINE THERE'S A ROUGH START. WHEN IT'S IDLE THE CAR SHAKES.

WHEN IT IS PARKED AND IDLING IT SOUNDS LIKE IT WANTS TO STALL. WHEN I AM DRIVING IT IT SHIFTS HARD AND THE TRANSMISSION STARTS SLIPPING. I TOOK IT TO A REPUTABLE MECHANIC FOR AN ASSESSMENT OF THE PROBLEM AND HE SAID HIS COMPUTER SAID THAT IT WAS THE TRACTION CONTROL MODULE IN THE TRANSMISSION AND THAT IT WOULD COST ABOUT $1500 TO REPAIR IT INCLUDING LABOR. HE CALLED THE DEALER TO SEE IF IT WAS IN STOCK AND THEY SAID THEY HAD MANY OF THEM. I WOULD ASSUME THAT THEY WOULD NOT STOCK A $700 PART IN THAT QUANTITY IF THEY WERE NOT HAVING QUITE A FEW PROBLEMS WITH THIS PART. OTHER SUV'S HAVE BEEN RECALLED AND I WAS WONDERING WHY MINE WAS NOT. I WOULD APPRECIATE IT IF YOU COULD LOOK INTO THIS MATTER FOR ME AND GET BACK TO ME WITH AN EXPLANATION. THANK YOU FOR YOUR TIME AS I MAY BE GETTING STUCK SOMEWHERE WITH MY WIFE AND CHILDREN IN THE CAR..

I HAVE 2 ONGOING ISSUES, 1ST IS THE CAR WILL BE DRIVING FINE THEN GET A CHECK ENGINE LIGHT AND HAVE A CODE FOR CYLINDER MISFIRE. CAR WAS AT DEALER MULTIPLE TIMES WITH ISSUE AND COULD NOT DUPLICATE WHILE UNDER EXTENDED WARRANTY. MYSTERIOUSLY THE INTAKE HAS TO COME APART AND BE REWORKED SINCE THE WARRANTY EXPIRED, AND STILL HAS SAME ISSUES. THE 2ND AND MORE CONCERNING ISSUE IS THE POWER STEERING. INITIALLY TOOK IN AND TOLD THE RACK AND PINION NEEDS CHANGED. STILL HAD SAME ISSUE AND TOLD POWER STEERING NOW NEEDS TO BE CHANGED, SO WE DID. SOUND AND STILL STIFF AFTER 2 RACKS AND 2 PUMPS. MECHANIC REFUSED TO WORK IT AGAIN. TOOK TO DEALER YESTERDAY. SAYS NEEDS NEW POWER STEERING PUMP. SO DEALER TOOK FOR A TEST DRIVE AND SAID IT'S STILL DOING IT AND NEEDS ANOTHER RACK AND PINION. AT WHAT POINT IS GMC THAT HAS A KNOWN SAFETY ISSUE WITH STEERING GOING TO FIX THIS ISSUE. I CAN'T KEEP THROWING MONEY AT THIS THING AND I CAN'T FEEL UNSAFE IN IT. WHAT CAN I DO?

THE SIDE CURTAIN AIRBAGS DEPLOYED COMING UP MY DRIVEWAY. THERE WAS NO COLLISION AND MY VEHICLE WAS TRAVELING ONLY 8 MILES PER HOUR. I HAVE ASKED FOR EXPLANATION FROM THE MANUFACTURER ON HOW THE AIRBAGS DEPLOYED IF THEY DID NOT MALFUNCTION. THEY REFUSE TO PROVIDE AN EXPLANATION OR PROOF MY VEHICLE WAS TESTED.

MY 2012 ACADIA ONLY HAS 112,000 MILES ON IT, AND I AM HAVING TRANSMISSION ISSUES. IT STARTED AS A VIBRATION (WASHBOARD SOUND) FOR ABOUT 5 SECONDS WHEN YOU WERE TRAVELING AT 55 TO 65 MPH. I HAVE HAD MY VEHICLE SERVICED REGULAR. AFTER HAVING IT IN THE SHOP 3 TIMES FOR THE SAME VIBRATION, I WAS FINALLY TOLD IT COULD BE THE TRANSMISSION. IT IS SAD THAT I HAVE SUCH A NICE VEHICLE AND WILL HAVE TO TRADE BECAUSE GM WILL NOT DO ANYTHING ABOUT THE FAULTY TRANSMISSION. TO REPLACE THE TRANSMISSION IT WILL COST AT LEAST $5,000.00. THIS COULD KEEP ME FROM PURCHASING ANOTHER GMC. THE PROBLEM IS ON GOING UNITL I DECIDE, REPAIR OR TRADE.

THE TORQUE CONVERTER IS FAILING PER DUBLIN GMC. THAT IS THE CAUSE OF THE STUTTERING. IN ADDITION, THE REAR LIFT GATE HAS FAILED AND WILL NOT STAY OPEN IN EITHER POWER OR MANUEL MODE. APPARENTLY MY VEHICLE MANUFACTUR DATE IS OUT SIDE THE RECALL MONTHS FOR THIS RECALL (PER DUBLIN GMC AND SELF CHECK ON THIS WEBSITE) RECALL # 5420 AND NHST #15V415000. HOW DO I GET THE MFG TO PAY FOR THIS POTENTIALLY LETHAL FAILURE (IT ALMOST GOT ME WHEN IT FAILED AS I WAS TAKING GROCERIES OUT OF BACK)

FRONT BLOWER MOTOR FOR DEFROST/HEATING/COOLING SYSTEM INTERMITTENTLY STOPS WORKING. SEEMS TO STOP WORKING MORE OFTEN IN RAIN, SNOW, AND COLD. HAS BEEN A SAFETY HAZARD, ESPECIALLY BECAUSE DEFROST DOESN'T WORK AND WINDSHIELD FOGS UP. VERY DIFFICULT TO SEE. BELIEVE THAT SOME OLDER ACADIA MODEL YEARS HAVE A RECALL ON THE BLOWER MOTOR BECAUSE IT GETS WET DURING RAIN AND SNOW AND NO LONGER WORKS. THE 2012 ACADIA HAS THE SAME PROBLEM. POTENTIALLY GETTING WET THROUGH A FAULT IN THE SUNROOF?? (08312020REAR BLOWER CONTINUES TO WORK.)

TRANSMISSION STUTTER

NHTSA ODI 11353502

THE TRANSMISSION IS SLIPPING OR SHUDDERING UNDER CERTAIN CONDITIONS. MOST FREQUENTLY NOTICEABLE AROUND THE SHIFT POINTS BETWEEN 2ND&3RD, OR 3RD & 4TH, ESPECIALLY WHEN THE ENGINE IS DOWNSHIFTING TO CLIMB A HILL. THERE IS A STRONG VIBRATION AND RPM BOUNCE A BIT BEFORE IT FINALLY ENGAGES AFTER A COUPLE SECONDS. I HAVE RECENTLY LEARNED THAT ACADIAS HAVE A LONG HISTORY OF TRANSMISSION PROBLEMS, NOTABLY THE TORQUE CONVERTER AND WAVE PLATE.

THE HEADLIGHT ASSEMBLY'S ARE MELTED AND HEADLIGHTS DON'T WORK. SEEMS THIS IS AN ONGOING PROBLEM WITH GMC HEADLIGHTS IN YEARS PAST THAT THEY CONTINUE TO NOT ADDRESS. I AM FURIOUS THAT DESPITE REPORTS AND RECALLS ON THIS ISSUE FROM MANY YEARS AND MANY MAKES AND MODELS THEY HAVE NOT ADDRESSED AND CONTINUE TO AVOID RECALLING ALL VEHICLES WITH THIS GARBAGE HEADLIGHT ASSEMBLY, THAT CAUSES HEADLIGHTS TO FAIL AND INCREASES RISK OF CAR FIRE. I WANT THIS REPAIRED BY THIS GARBAGE COMPANY AND SOMETHING DONE TO MAKE THEM STOP UTILIZING THESE UNSAFE AND FAULTY ASSEMBLIES.

I STARTED HAVING STEERING PROBLEMS WHEN I WOULD SLOW DOWN TO MAKE A TURN ON A CITY STREET. THE STEERING WAS VERY TIGHT. UNSAFE CONDITION WITHOUT WARNING. I HAD THE POWER STEERING UNIT REPLACED, THEN I WAS TOLD THE RACK AND PINION HAD METAL IN THEM AND NEEDED TO BE REPLACED. MECHANIC WAS UNABLE TO FLUSH OUT THE METAL. I PICKED UP THE CAR TODAY AFTER A COST OF $2,200. DROVE HOME ON CITY STREETS, SAME PROBLEM ONLY TIGHTER TURNING. CALLED THE MECHANIC AND WAS TOLD TO RETURN THE CAR. JUST LUCK I HAVE ANOTHER CAR TO DRIVE. SHOULD BE A RECALL ON THIS VERY UNSAFE CONDITION. *TR
