NHTSA Complaint #11279421 — 2018 GMC ACADIA

THE VEHICLE WILL NOT ALWAYS GO INTO PARK. IN ORDER TO GET IT INTO PARK YOU HAVE TO REPEATEDLY SHIFT OUT OF PARK AND BACK INTO PARK UNTIL IT WILL GO INTO PARK. IF IT IS NOT IN PARK THE VEHICLE WILL NOT LOCK AND WILL NOT POWER DOWN. SINCE IT WILL NOT GO INTO PARK IF THE VEHICLE WAS ON A HILL AND IT DID NOT GO INTO PARK THEN IT WOULD HAVE THE CHANCE TO ROLL DOWN THE HILL. I HAVE NOT ATTEMPTED TO SEE IF IT WILL ROLL DOWN THE HILL NOR AM I GOING TO TRY BUT SEEING HOW IT SHOWS ON THE INSTRUMENT CLUSTER THAT THE VEHICLE IS IN NEUTRAL I'M SURE IT WILL ROLL IF GIVEN THE CHANCE. WHEN SHUTTING OFF THE VEHICLE AFTER YOU HAVE PUT THE VEHICLE IN PARK ON THE GEAR SELECTOR A MESSAGE COMES UP ON THE SCREEN THAT SAYS SHIFT TO PARK IT HAS TAKEN UP TO 20 TRIES OF SHIFTING THE VEHICLE IN AND OUT OF PARK UNTIL PARK WILL ENGAGE. AS YOU CAN SEE IN THE PICTURE ALL GAUGES ARE AT THEIR LOWEST POINT SHOWING NO POWER TO THE VEHICLE AND THE SHIFT INDICATOR IS IN THE NEUTRAL POSITION WITH THE MESSAGE ON THE DISPLAY READING SHIFT TO PARK.
