2008 GMC ACADIA Complaints

THE TRANSMISSION FAILED CLIMBING A HILL WITH AN APPROXIMATE 10% INCLINE. MY WIFE WAS TRANSPORTING TWO YOUNG CHILDREN AT THE TIME AT HAD TO TURN HAZARDS ON WHILE THE VEHICLE CREPT UP A VERY HEAVILY TRAVELED ROADWAY (US HIGHWAY 31). THIS OCCURRED AFTER THE TRANSMISSION WAS REPAIRED TWO WEEKS EARLIER FOR THE SAME PROBLEM. AT THAT TIME, I WAS INFORMED BY GMC THAT IT WAS THE INPUT SPEED SENSOR. TURNS OUT IT IS TRANSMISSION FAILURE, WHICH I HAVE SINCE LEARNED IS VERY COMMON WITH THIS MODEL. AFTER READING VAST ENTRIES OF MANY OTHER ACADIA USERS WITH THE SAME PROBLEM, I CAN'T HELP BUT THINK THAT THIS IS A DESIGN FLAW. I MEAN, HOW MANY TRANSMISSIONS FAIL AT 48,000 MILES. I'M JUST GLAD MY WIFE WASN'T DRIVING AT NIGHT, ON A LONG TRIP, OR ON THE INTERSTATE, WHICH WOULD HAVE LEFT MY CHILDREN AND HER IN A VERY VULNERABLE POSITION. FOR THE PRICE OF THIS VEHICLE, I WOULD EXPECT RELIABLE USAGE UP TO AT LEAST 100,000 MILES. IN MY OPINION, BECAUSE OF RELIABILITY ISSUES AND THE SHEAR VOLUME OF PEOPLE WITH THE SAME PROBLEM, GMC SHOULD RECALL THESE VEHICLES AND REPLACE THE TRANSMISSIONS WITH WHAT THEY ARE NOW INSTALLING ON THE NEWER MODELS. THE FACT THAT THEY HAVE IMPROVED THE TRANSMISSIONS ON NEWER MODELS PROVES THERE IS A FLAW WITH MY MODEL YEAR. WHY ELSE WOULD THEY CORRECT IT. THANKS FOR YOUR CONSIDERATION. *TR

AIRBAG PASSENGER PRESENCE SENSOR FAILED DESPITE LIMITED SEAT USE. REPAIR COST ALMOST $800.

CAR HAS BEEN SHAKING AND KNOCKING WHEN I BRAKE. I REPORTED THIS ISSUE TO THE LOCAL GMC DEALERSHIP WHEN I FIRST BROUGHT IT IN. I ACTUALLY BROUGHT IT IN TO FIX SOMETHING ELSE. THIS CAR HAS MANY ISSUES. THE MOST RECENT TIME I TOOK IT IN WAS ON SEPTEMBER 4TH. THEY WANT TO CHARGE ME OVER $2000 JUST TO TRY TO FIND THE PROBLEM EVEN THOUGH THEY ALREADY TOLD ME IT IS THE TRANSMISSION. THEY KNOW THAT GMC ACADIAS HAVE BEEN HAVING ISSUES WITH TRANSMISSIONS (CHECK GMC TRANSMISSIONS BOARD AT EDMUNDS.COM). ACTUALLY GMC SHOULD DO A RECALL OF THESE VEHICLES FOR THIS TRANSMISSION ISSUES AS MANY CARS ARE ALL HAVING THE SAME ISSUE. I ONLY HAVE 72000 MILES ON THIS CAR AND I BOUGHT IT BRAND NEW. SO IT IS AN ABSOLUTE SHAME THAT THIS CAR IS ALWAYS HAVING TRANSMISSION ISSUES. I THINK THE DEALERSHIP ALREADY KNEW THAT IT WAS A TRANSMISSION ISSUE WHEN I BROUGHT IT IN SEVERAL MONTHS AGO BUT THEY NEVER FIXED IT OR ADDRESSED IT THEN. I HAVE THE RECORDS TO PROVE IT. NOW THEY WANT TO SAY IT IS A TRANSMISSION ISSUE AND WANT ME TO PAY $2000 JUST TO DO AN ASSESSMENT.

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

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

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

POWER STEERING INTERMITTENTLY WILL NOT WORK.. PULLED INTO PARKING SPOT AND THE VEH STARTED A LOUD SCREACHING SOUND FOR SEVERAL MINUTES. AGAIN WHILE TRAVELING DOWN THE ROAD THE STEERING COMPLETELY CUTS OUT. IN MAY OF 2013 THE POWER STERRING RACK WAS REPORTED TO ME THAT IT WAS LEAKING ( WHILE IN THE DEALER FOR TRANSMISSION REPLACEMENT ). THE GMC DEALER, SERRA GMC IN WASHINGTON , MI., REPLACED THE STEERING RACK AND CHARGED US FOR THE NEW RACK. A FEW WEEKS LATER THE POWER STEERING BEGAN TO CUT OUT WHILE DRIVING. WE TOOK VEH IN FOR SERVICE AND PAID FOR A DIAGNOSTIC OF THE PROBLEM AND WE WERE TOLD THAT THEY COULD NOT DUPLICATE THE POWER STEERING ISSUE.. BUT SAID IT WAS PROBRABLY THE STEERING PUMP.IN ADDITION WE WERE TOLD THE TIMING CHAIN COVER WAS LEAKING OIL AND THE TIMING CHAIN WOULD NEED REPLACING. THEY GOT GM TO PAY A PORTION OF THE REPAIR. THEY WANTED OVER $700 TO REPLACE THE POWER STERRING PUMP BUT WOULD NOT GAURANTEE THAT WOULD FIX THE PROBLEM. THIS IS CRAZY WE JUST PAID TO HAVE THE STEERING RACK REPLACED AND A PORTION OF THE TRANSMISSION REPLACEMENT AND NOW THE STEERING PUMP. THE VEH CURRENTLY HAS LESS THAN 79,000 MILES. I REALLY FEEL THIS IS AN UNSAFE CONDITION THAT NHTSA NEEDS TO LOOK INTO. MY DAUGHTER ( WHO IS 15 YEARS OLD ) IS CURRENTLY A "LEARNING DRIVER" WHO DRIVES THIS VEH ( WITH A LICENSED DRIVER IN THE VEH) AS PART OF HER LOGGED DRIVING TIME. I'M CONCERNED THAT THE STEERING WILL FAIL WHILE SHE IS DRIVING. GM WOULD BE LIABLE FOR ANY DAMAGE AND INJURIES IF THE STEERING FAILS WHILE SHE IS BEHIND THE WHEEL. ..

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

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