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.

TOOK OUR ACADIA IN ON 9/25 AFTER SEVERAL WEEKS (STARTED THE WEEK OF 8/26) OF THE SHIFT TO PARK INDICATOR LIGHT KEPT COMING ON. THE DEALERSHIP HAD IT FOR SEVERAL WEEKS (P/U 10/16) BECAUSE THEY COULDN'T GET THE PARTS DUE TO THE GM STRIKE. WE HAVE HAD IT BACK THREE WEEKS AND IT HAS BEGUN AGAIN WITH THE SHIFT TO PARK LIGHT. WE KEEP THE PARKING BREAK ON JUST IN CASE, DON'T TRUST IT. HAVE ANOTHER SERVICE APPOINTMENT ON 11/15. WE WILL SEE WHAT HAPPENS.

DEAD BATTERY AT 12,973 MILES. REPLACED BATTERY. ALSO AT 13013 MILES 'PUT IN PARK' MESSAGE AND BEEPING WHEN THE CAR IS IN PARK. CAR WILL NOT SHUT OFF, CANNOT BE LOCKED AND CONTINUES LOUD BEEPING. REPAIRED BY DEALER. AT 13268 MILES 'PUT IN PARK' MESSAGE AND BEEPING WHEN CAR IS IN PARK IS HAPPENING AGAIN. ALSO, DASHBOARD LIGHTS SOMETIMES DO NOT COME ON AND SOMETIMES SHUT OFF WHEN DRIVING. IS GOING BACK FOR REPAIR AGAIN. BATTERY IS LOSING AMPS.

I PUT MY 2018 ACADIA IN PARK IN MY GARAGE (A FLAT STATIONARY SPOT) AND I RECEIVE A MESSAGE THAT STATES 'PUT VEHICLE IN PARK', WHICH IT ALREADY IS IN PARK AND AS A RESULT THE ENGINE WON'T SHUT OFF. I HAVE HAD THIS OCCUR SEVERAL TIMES OVER THE PAST MONTH, BUT MOST RECENTLY OCCURRED ON OCTOBER 24, 2019. IT IS MY UNDERSTANDING IT IS POSSIBLY A BAD SHIFTER ASSEMBLY WHICH NOT ONLY WILL KEEP THE VEHICLE FROM SHUTTING OFF, IT CAN ALSO NOT HOLD THE VEHICLE IN PARK. I HAVE RESEARCHED THIS ISSUE AND I AM DISAPPOINTED TO DISCOVER THAT GMC IS AWARE OF THIS ISSUE OCCURRING WITH THE VEHICLES. THIS IS A SERIOUS ISSUE ESPECIALLY IF IT WILL FAIL TO HOLD YOUR VEHICLE IN PARK.

1 OUT OF 2 TIMES A DAY WHEN I PUT THE VEHICLE IN PARK IT GIVES ME A WARNING TO SHIFT TO PARK ON THE ELECTRONIC DASH. EVEN THOUGH THE SHIFT IS SITTING IN THE PARK POSITION. SO I HAVE TO RESTART THE CAR, TAKE IT OUT OF PARK AND SHIFT BACK TO PARK MULTIPLE TIMES BEFORE THE WARNING GOES AWAY. THIS WARNING PREVENTS THE CAR FROM COMPLETELY SHUTTING DOWN

WARNING MESSAGE SAYS "SHIFT TO PARK". MESSAGE DOES NOT GO OFF UNTIL YOU TURN CAR ON AND OFF SEVERAL TIMES; PUTTING THE CAR IN REVERSE, THEN DRIVE; THEN SHIFTING BETWEEN GEARS BACK AND FORTH. MAY TAKE 20 MINUTES TO GET THE MESSAGE LIGHT TO GO OFF. GMC HAS TRIED REPLACING GEAR SHIFT, PART OF GEAR TOP. AFTER 5 ATTEMPTS IN TRYING TO FIX THE ISSUE, MY CAR SITS AT THE DEALERSHIP FOR AN ADDITONAL 4 WEEKS WAITING FOR A HARNESS FIX (WHICH THERE IS NO PART FOR). THE CAR ALWAYS ROLLS BACKWARDS WHEN THE MESSAGE FINALLY GOES OFF. THIS IS A MAJOR SAFETY ISSUE. IS THE CAR REALLY IN PARK?
