2018 GMC ACADIA Complaints

MY CAR KEEPS GIVING NOTICE OF IT NOT BEING IN PARK, WHEN ITS CLEARLY SHIFTED INTO PARK. IT WONT SHUT DOWN, LET YOU LOCK DOORS. JUST BEEPS UNTIL IT FINALLY REALIZES ITS IN PARK. EVEN AFTER CONTINUOUSLY RE SHIFTING INTO PARK. WORSE IN THE SUMMER MONTHS. IT NEEDS TO BE FIXED AS MANY OTHERS ARE HAVING THE SAME ISSUE! *TR

WHEN I SHIFT THE TO PARK AND TRY TO TURN OFF MY CAR THE SHIFT TO PARK LIGHTS UP AND I HAVE TO DOWN SHIFT AND THEN SHIFT TO PARK AGAIN TO GET MY CAR TO SHUT OFF ALSO THE AIR COMPRESSOR HAS ALREADY QUIT WORKING WITH LESS THAN 40K MILES ON IT. *TR

MY VEHICLE WAS STATIONARY. I STOPPED THE VEHICLE AND PLACED THE SHIFT LEVER INTO THE PARK POSITION. WHEN I PRESSED THE START/STOP BUTTON, THE BUTTON'S AMBER WARNING LIGHT CAME ON, AN AUDIBLE WARNING BEGAN SOUNDING AND ALL INSTRUMENT LIGHTS STAYED ON. WHEN I LOOKED AT THE DRIVER'S DISPLAY, IT STATED, "SHIFT TO PARK". (THE SHIFT LEVER WAS ALREADY IN THE PARK POSITION. I COULD NOT SHUT THE VEHICLE DOWN AND COULD NOT LEAVE THE VEHICLE IN THAT CONDITION. I CONTINUED TO MOVE THE SHIFT LEVER FROM DRIVE TO PARK AND AFTER 8-10 SHIFTS, THE VEHICLE FINALLY RECOGNIZED THAT IT WAS IN PARK. THEN, THE START/STOP BUTTON FUNCTIONED CORRECTLY. UPON INVESTIGATION, I FOUND THAT THIS IS A VERY COMMON PROBLEM WITH 2017-2018 GMC ACADIAS (THERE IS EVEN A CLASS ACTION LAW SUIT PENDING). SOME OWNERS EVEN REPORT THEIR VEHICLES ROLLING WHEN IN THIS CONDITION. AS OF THIS DATE (5/19/2020) GM HAS NOT RECOGNIZED THIS AS A DESIGN PROBLEM AND HAS NOT ISSUED A RECALL. THIS IS OBVIOUSLY A DESIGN ISSUE SINCE IT HAPPENS WITHIN AND OUT OF THE 3YR/36,000 MILE WARRANTY. IF IT HAPPENS AT 36,500 MILES THE VEHICLE OWNER IS OUT OF LUCK! THIS IS ALSO, OBVIOUSLY, A SAFETY ISSUE. THANKS FOR YOUR TIME AND HELP. *TR

WHEN YOU TRY TO PUT THE CAR IN PARK IT STATES THAT ITS NOT IN PARK. IT WILL NOT SHUT OFF. YOU HAVE TO START THE CAR AND SHUT OFF MULTIPLE TIMES AND HOPE THAT WORKS. I'VE LOOKED IT UP AND THERE IS A LAWSUIT ABOUT IT BUT NO RECALL. IT DOES THIS EVERY TIME I DRIVE SOMEWHERE AND TRY TO TURN MY CAR OFF. *TR

I HAVE RECEIVED THE 'SHIFT TO PARK' ERROR MESSAGE ON THE DASH WHEN THE CAR IS ALREADY IN PARK. ONE TIME WITH THE CAR OFF, THE ERROR MESSAGE ON, THE CAR STARTED TO ROLL DESPITE IT BEING IN PARK. I HAD TO RESTART THE CAR, SHIFT THE SHIFTER DOWN THEN BACK TO PARK BACK DOWN AND BACK TO PARK BEFORE THE CAR WOULD RECOGNIZE THE SHIFTER WAS IN PARK. EACH TIME THIS HAPPENED WHEN I WAS IN A PARKING SPOT AND IN MY GARAGE.

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT AFTER STOPPING THE VEHICLE AND PLACING THE GEAR SHIFTER IN PARK, A MESSAGE DISPLAYED TO SHIFT THE VEHICLE INTO PARK.

NEITHER THE MANUFACTURER NOR THE DEALER WERE NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 41,000. THE VIN WAS INVALID.

WHEN GEAR LEVER IS SHIFTED INTO PARK AND YOU TRY TO TURN OF THE ENGINE A NOTICE COMES ON TELLING YOU TO PUT YOUR CAR INTO PARK. I CAN NOT TURN OFF THE CAR UNTIL THIS MESSAGE DISAPPEARS. SOMETIMES IT TAKES 7 OR MORE TRIES TO FINALLY BE ABLE TO SHUT OFF THE CAR. IF I LEAVE IT WITH THE MESSAGE THEN ALL ELECTRICAL SEEMS TO STAY ON.

WHEN I SHIFT THE CAR TO PARK AFTER DRIVING I RECEIVE A "SHIFT TO PARK" MESSAGE. THE VEHICLE IS IN PARK BUT WILL NOT REGISTER.

WHEN ATTEMPTING TO TURN THE VEHICLE OFF AFTER SHIFTING TO PARK AND THEN PRESSING THE START/STOP BUTTON, THE VEHICLE GIVES AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK" EVEN THOUGH THE SHIFT LEVER IS IN THE PARK POSITION. THE ERROR MESSAGE PREVENTS THE VEHICLE FROM SHUTTING DOWN. THIS OCCURS WHEN THE VEHICLE IS STOPPED, PUT INTO PARK, AND THEN WHEN ATTEMPTING TO SHUT DOWN THE VEHICLE.
