NHTSA Complaint #11325129 — 2018 GMC ACADIA

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
