NHTSA Complaint #11232515 — 2017 GMC ACADIA

AFTER PARKING THE VEHICLE, SHIFTING INTO PARK AND TURNING OFF THE ENGINE, A WARNING MESSAGE APPEARS STATING TO SHIFT THE CAR INTO PARK. THE CAR IS IN PARK, BUT THERE MUST BE SOME TYPE OF SENSOR FAILURE. I AM PROHIBITED FROM COMPLETING SHUT DOWN OF THE VEHICLE UNTIL I CLEAR THE WARNING MESSAGE. WHEN THIS ISSUE FIRST AROSE, I COULD "JIGGLE" THE SHIFTER A BIT, AND THE MESSAGE WOULD CLEAR. NOW, ABOUT TWO WEEKS LATER, I NEED TO START THE CAR, MOVE THE SHIFTER BETWEEN GEARS, AND THEN BACK INTO PARK. AFTER 2 - 3 TIMES REPEATING THE PROCEDURE, THE WARNING MESSAGE USUALLY CLEARS. THE VEHICLE HAS BEEN TAKEN IN FOR SERVICE. A NEW SHIFTER HAS BEEN ORDERED. THE PART IS ON BACK ORDER.
