NHTSA Complaint #11265360 — 2018 GMC ACADIA

WHEN TURNING OFF THE VEHICLE, A WARNING MESSAGE COMES ON SAYING "SHIFT TO PARK" EVEN THOUGH THE VEHICLE IS IN PARK. THE SHIFTER READS PARK AND SO DOES THE DASH. VEHICLE IS UNABLE TO BE COMPLETELY TURNED OFF OR LOCKED WITH THIS MESSAGE APPEARING. IT REQUIRES TURNING VEHICLE ON AND OFF, MOVING SHIFTER IN AND OUT OF PARK, JIGGLING SHIFTER BUTTONS, ETC. THIS CAN TAKE ONE TRY OR MULTIPLE TRIES. I JUST HAD THIS FIXED BY THE DEALERSHIP (REPLACED SHIFT CONTROL) AND WAS DISAPPOINTED TO FIND THAT THIS IS A KNOWN ISSUE, AFFECTING MANY VEHICLES AND IT IS STILL THE RESPONSIBILITY OF THE VEHICLE OWNER TO PAY FOR THE EXPENSE IF THE BUMPER TO BUMPER WARRANTY IS EXPIRED. THE SHIFTER RUNS THE POWER TRAIN! WHY IS THIS NOT UNDER THE POWER TRAIN WARRANTY AND WHY IS THIS NOT A RECALL? NOW, IN RESEARCHING, I'M SEEING THAT MANY HAVE HAD IT HAPPEN AGAIN AFTER THE ISSUE HAS BEEN "FIXED". DEALER TECH NOTES TSB 19-NA-206 IN HIS REPORT.
