What 260 owners told NHTSA about the 2015 GMC Acadia Limited

EVERY TIME I GO TO THE GAS STATION AFTER FILLING UP MY TRUCK WITH GASOLINE, MY VEHICLE WILL NOT START UP RIGHT AWAY. I HAVE TO PRESS THE GAS PEDAL LIGHTLY IN ORDER FOR IT TO START UP. THIS JUST STARTED RECENTLY. *TR

IMMEDIATELY AFTER FILLING THE TANK WITH GAS, I STARTED THE ENGINE AND IT ACCELERATED TO FULL CAPACITY. THE ENGINE HAD MADE CLICKING SOUNDS, AND OTHER SOUNDS WHEN IT STARTED.

INJECTORS STICKING OPEN. BROUGHT TO DEALER AT 26,000 MILES AFTER IT BROKE DOWN 200 MILES AWAY. THAT WAS AFTER THE GMC DEALERSHIP TOLD US IT SHOULD BE OK TO DRIVE. INJECTOR STUCK OPEN AND THE DEALER WE BROKE DOWN AT SAID THE VEHICLE COULD CATCH FIRE IF WE KEPT DRIVING. THEY REPLACED THE INJECTOR THAT WAS THE ISSUE. NOW LAST WEEK ANOTHER DIFFERENT INJECTOR FAILED. THIS TIME THE INSIDE OF THE VEHICLE FILLED WITH THE SMELL OF FUEL AND WAS VIOLENTLY SHAKING ON THE ROAD. WE COULDN'T PULL OVER RODGER AWAY BECAUSE WE WEREN'T ON A SAFE ROAD TO STOP AT. ENDED UP DRIVING IT TO THE NEAREST GAS STATION. MY WIFE AND SON WERE IN THE CAR SCREAMING AND CRYING AT HOW BAD THE CAR WAS DRIVING AND SMELLED. WE WERE VERY FEARFUL THE CAR WAS GOING TO CATCH ON FIRE. GMC ONCE AGAIN STATES IT'S AN ISOLATED INCIDENT AFTER IT'S HAPPENED TWICE WITHIN MONTHS. AND THEY REFUSE TO REPLACE ALL INJECTORS OR RECALL THE VEHICLE. WE TOLD THEM WE DIDN'T FEEL SAFE DRIVING IT BUT THEY DON'T CARE TO HEAR IT. BOTH TIMES WE WERE DRIVING BETWEEN 55-70MPH AND IT'S A VERY SCARY UNSAFE FEELING WHEN IT HAPPENS.

WHILE DRIVING IN HEAVY CITY TRAFFIC, MY WARNING LIGHTS CAME ON FOR "REDUCED POWER", 'TRACTION CONTROL" MALFUNCTION, 'STABILITRAC AND ABS LIGHTS CAME ON. POWER REDUCED TO 25MPH. I WAS CLOSE TO THE DEALERSHIP AND WENT THERE RIGHT AWAY. THE SERVICE WRITER TOLD ME I WOULD HAVE TO WAIT AT LEAST 2 TO 4 HRS BEFORE ANYONE COULD LOOK AT. MY MILEAGE WAS 36,432...432 MILES OUT OF BUMPER TO BUMPER WARRANTY...HE TOLD ME THE CHARGES FOR DIAGNOSING WOULD BE $130. I AGREED. THEN HE EXPLAINED THAT THE THE LOW HP FUEL PRESSURE/PURGE SOLENOID WAS STUCK OPEN, DIANOSE CODES WERE PO191 AND PO496, THEY REPLACED A HIGH PRESSRE FUEL PUMP, R&R INTAKE PLENUM TO REPLACE FUEL RAIL PRESSURE SENSOR AND REPLACE A PURGE CONTROL SOLENOID. COST TO ME WAS $1,760.51 ($866.06 LABOR- $820.43 PARTS -$30.00 MISC.CHARGE-$82.29 MISC.DISCOUNT- TAXES OF $126.31. I DON'T UNDERSTAND WHY THEY COULDN'T BE MORE LENIENT WITH MILEAGE ON WARRANTY. I PURCHASED THIS VEHICLE NEW FROM THEM AND HAVE COMPLETED ALL MY SERVICE WORK THERE. THIS WAS A SCARY SITUATION IN NOON RUSH HOUR TRAFFIC WITHOUT ANY ROADSIDE PULL OFF AT THE TIME. COULD THERE HAVE BEEN A DEFECTION FUEL PUMP? I WAS TOLD BY SERVICE WRITER "IF YOU HAD DRIVEN ANY FURTHER MORE DAMAGE WOULD HAVE HAPPENED TO ENGINE BLOCK".

APPROXIMATELY 2 MONTHS AGO, THE VEHICLE SHUT DOWN IN THE MIDDLE OF HIGH SPEED TRAFFIC. SEVERAL WARNING INDICATORS APPEARED (E.G. "STABILITRACK OFF", ETC.), THEN THE VEHICLE IMMEDIATELY SHUT DOWN. PROPULSION STOPPED AND THE VEHICLE SLOWLY CAME TO A STOP. LUCKILY, MY WIFE WAS ABLE TO STEER OFF TO THE SIDE OF THE ROAD SAFELY. IT WAS TOWED TO THE DEALER, ALTHOUGH IT WAS ABLE TO RESTART. THE DEALER HAD FIXED IT, THEN RETURNED THE VEHICLE TO US. TWO MONTHS LATER, THE IDENTICAL THING OCCURRED; SAME ERROR MESSAGES FOLLOWED BY THE VEHICLE SHUTTING DOWN, IN THE MIDDLE OF DRIVING IT. WE TOOK IT BACK TO THE DEALER, AND A DIFFERENT PROBLEM WAS DIAGNOSED (WITH THE VEHICLE OUT OF SERVICE > 2 WEEKS THIS TIME). WE HAVE LOST CONFIDENCE IN THE VEHICLE, AND FEEL IT IS UNSAFE TO DRIVE.

AFTER PICKING UP OUR NEW TRUCK WE NOTICED THAT THE VEHICLE'S ENGINE WAS SHORT JUMPING AT LOW SPEEDS, ESPECIALLY WHEN IN TRAFFIC - AT FIRST WHEN THIS OCCURS YOU HAVE TO ALMOST ASK YOURSELF DID I HIT THE GAS PEDAL INSTEAD OF THE BRAKES. AFTER ONLY A COUPLE WEEKS OF OWNERSHIP WE DROPPED OFF OUR NEW VEHICLE TO BE REPAIRED. DEALER 'S GMC CERTIFIED TECHNICIAN HAD TO CONSULT WITH GMC CORPORATE TO HELP TROUBLESHOOT AND THEN DECIDED TO REPLACE THE LOWER AND UPPER ENGINE VALVE COVERS, AND THE TRANSMISSION CONTROL MODULE; WHICH WAS A QUICK FIX THAT LASTED A LITTLE OVER A WEEK. NOW OUR BRAND NEW VEHICLE IS ONCE AGAIN A LEMON AND REPEATING THE ORIGINAL ISSUE. AFTER CONTACTING GMC AND AFTER REQUESTING ANOTHER SAFER NEW VEHICLE SINCE ITS COMMON SENSE THAT A BRAND NEW TRUCK SHOULD NOT HAVE ANY INTERNAL ENGINE OR TRANSMISSION PROBLEMS BEING THAT WE HAVE A FOUR YEAR OLD, TWO YEAR OLD, AND A NEWBORN, I AM A CONCERNED FOR MY FAMILY'S SAFETY; GMC CORPORATE RESPONSE WAS "DON'T YOU THINK THAT 1 CAR IN 300,000 WOULD HAVE AN ISSUE"... AT THE END WE ARE NOT TALKING ABOUT A LOOSE BELT OR WHEEL OUT OF BALANCE, BUT AN INTERNAL PROBLEM WHICH THERE TECH TOLD MY WIFE THAT HE COULD NOT GUARANTEE THAT THE CARE WAS SAFE DURING HIS TEST DRIVE. THE DEALER'S MANAGER RESPONSE WAS "THE CAR IS NOT OUR PROBLEM WHEN IT LEAVES OUR LOT", IT THEN FALLS UNDER THE MANUFACTURE WARRANTY; WHICH MAKES SENSE, BUT ONCE AGAIN WE ARE TALKING ABOUT A BRAND NEW CAR, NOT A CAR THAT HAS SOME USAGE. NOW TWENTY DAYS IN THE SHOP AND ONLY 2,000 MILE ON THE VEHICLE THEY DECIDED TO REPLACE THE TRANSMISSION, BUT STILL CAN'T TELL US WHAT IS WRONG WITH THE VEHICLE; WHICH NOW WHEN BRAKING ON THE HIGHWAY IT DOWNSHIFTS HARD AND ALMOST FEELS LIKE SOMEBODY REAR ENDED YOU.
