2018 GMC Acadia

THE CAR WOULD NOT TURN OFF WHEN PUT IN PARK WHEN THE CAR WAS STOPPED. THE ENGINE WOULD TURN OFF, BUT THE ELECTRICAL DEVICES (LIGHTS, RADIO, ODOMETER READINGS, ETC.) WOULD REMAIN ENGAGED. THE WARNING INDICATOR SAID THE VEHICLE WAS NOT IN PARK AND IT WOULD TAKE 5-10 MINUTES OF TURNING THE ENGINE ON AND OFF, AND SHIFTING BACK AND FORTH IN AND OUT OF GEAR BEFORE THE CAR WOULD TURN OFF COMPLETELY. A SEARCH ON LINE INDICATED SEVERAL PEOPLE COMPLAINING OF THE SAME ISSUE. THIS CAR IS 2 YRS OLD WITH LESS THAN 40K MILES. IT WAS MAINTAINED AS A COMPANY LEASED VEHICLE BY US BEFORE BEING PURCHASED BY US, SO WE KNOW IT HAS BEEN PROPERLY MAINTAINED. WE ENDED UP HAVING TO HAVE THE SHIFT COLUMN REPLACED. *TR

SHIFT TO PARK KNOWN ISSUE HAS STARTED. I'VE HAD THE CAR FOR 1 YR. 5 MONTHS. I KNOW THERE ARE LAWSUITS ON THIS ISSUE. CONTINUOUS ISSUE AND GETTING WORSE. THIS NEEDS TO BE TAKEN CARE OF BY GM. IT IS EPIDEMIC IN THEIR ACADIAS. STATIONARY AND PUTTING IT INTO PARK. IT DOESN'T RECOGNIZE IT'S IN PARK! IT'S BEEN OCCURRING OFF AND ON OVER A WEEK, NOT TODAY, EVERY TIME I TRY TO TURN OFF THE VEHICLE.

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

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. THE CONTACT SHIFTED THROUGH THE GEARS AND THE VEHICLE OPERATED AS INTENDED. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE MANUFACTURER NOR THE DEALER WERE NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 41,000. THE VIN WAS INVALID.
