2018 GMC ACADIA Complaints

Shift to park not happening. Stop the car and then the shift to part indicator shows up in the driver information center. So far I have been able to clear it out. Going into the dealer first thing in the morning. I have looked and there appears to be a class action on this issue and a TSB. I just bought this vehicle and was not told about this issue.

Was driving down a dirt road and suddenly the airbags deployed for no reason. Ruined the car.

I have numerous warnings, shift to park, steering, cross traffic, this endangers myself and anyone else around me, i have read several class action suits involving these problems and it could cause my vehicle to pose a danger, I have taken my vehicle in to a certified dealer and they state there is no known recalls associated with my vehicle which is strange because GMC knows that there are thousands of vehicles having the same problem, did I buy a lemon? These problems are clearly manufacture related and in no way normal wear and tare. I should not have to compensate these issues when I paid near 40,000 for it

SHIFT TO PARK WARNING IS COMING ON, I AM NOT ABLE TO TURN THE CAR OFF. THE CAR IS ROLLING EITHER FORWARD OR BACKWARD WHILE IN THE PARKED POSITION. I HAVE TO TURN THE CAR ON AND OFF MANY TIMES PLUS PUT IT IN FORWARD, REVERSE, NEUTRAL AND MOST OF THE TIME THAT STILL DOES NOT FIX THE PROBLEM. THE CAR WILL NOT TURN OFF, AND IT IS ROLLING FORWARD OR BACKWARD WHILE IT IS PARKED.

WHEN I PUT MY CAR IN PARK AND TURN OFF IT WILL RANDOMLY SAY "SHIFT TO PARK" IT STARTED DOING THIS IN AUG OR SEPT 2019 THE CAR WAS UNDER WARRANTY AND I BROUGHT IT TO A DEALER TO "FIX". FAST FORWARD APRIL 2021 IT STARTED TO SAY SHIFT TO PARK AGAIN AND CAR IS NO LONGER UNDER WARRANTY. CALLED DIFFERENT DEALERS EVEN THE ONE I BROUGHT THE CAR TO FIX PROBLEM (THAT WAS A JOKE), THEY KNOW ITS A PROBLEM AND SAYING SINCE THAT PART GOT FIXED IN 2019 WITH A BAD PART AND NOW THERE IS A A NEWER FIX THAT SHOULD WORK BETTER, BUT I WILL HAVE TO PAY FOR DIAGNOSTIC TEST AND PART AGAIN. AGAIN THEY KNOW IT IS A PROBLEM WITH THESE CARS AND IT NEEDS TO BE RECALLED. I HAVE TO TURN THE CAR OFF AND ON RESHIFT, PUSH THE SHIFTER HARDER, ETC TO GET THE MESSAGE TO GO AWAY SO I CAN TURN MY CAR OFF.

WILL SAY THAT VEHICLE IS NOT IN PARK AND WILL NOT SHUT OFF. CONSTANTLY SAYS REMOTE DEVICE NOT DETECTED DESPITE ME USING THE REMOTE TO START OR TURN THE VEHICLE OFF. WILL NOT OFFICIALLY TURN OFF SAYING REMOTE NOT DETECTED AND RADIO WILL STAY ON. I CAN USE THE REMOTE TO TURN IT BACK ON BUT THE RECEIVE THE SAME ERROR MESSAGE, THIS HAPPENED 4 TIMES WHEN WE PARKED AT THE BALL FIELDS SUNDAY. HOW FRUSTRATING THAT WE HAD TO HANG BY THE CAR HOPING THE NEXT TRY IT WOULD COOPERATE. THIS IS CLEARLY A PROBLEM THAT GMC NEEDS TO FIX. THESE ARE NOT ONE TIME ERRORS, I HAVE SOME TYPE OF ERROR DAILY.

THE ACADIA HAS 23,700 MILES ON AND THE TIRES ARE WEARING OUT. NEW TIES SHOULDN'T BE NEEDED UNTIL 60,000 MILES. THIS IS A LOT OF DIFFERENCE IN WHAT SHOULD BE OBTAINED BY THESE TIRES.

VEHICLE WHEN PUT IN PARK DOES NOT SHUT OFF. TOOK TO HILLSDALE GMC 1/13/20 AND IT WAS OKAY FOR AWHILE. THIS SAME PROBLEM STARTED ABOUT 3 MO AGO AGAIN. PUT IN PARK WILL NOT SHUT OFF. YOU MAY HAVE TO RESTART, PULL INTO GEAR, BACK TO PARK, OVER AND OVER! VERY ANNOYING ESPECIALLY IF YOU HAVE AN APPOINTMENT!

WHEN PARKING CAR IT KEEPS TELLING US TO PARK WHEN IT IS IN PARK AND WE CAN TURN IT OFF
