WHEN GEAR LEVER IS SHIFTED INTO PARK AND YOU TRY TO TURN OF THE ENGINE A NOTICE COMES ON TELLING YOU TO PUT YOUR CAR INTO PARK. I CAN NOT TURN OFF THE CAR UNTIL THIS MESSAGE DISAPPEARS. SOMETIMES IT TAKES 7 OR MORE TRIES TO FINALLY BE ABLE TO SHUT OFF THE CAR. IF I LEAVE IT WITH THE MESSAGE THEN ALL ELECTRICAL SEEMS TO STAY ON.

VEHICLE WILL NOT ACKNOWLEDGE THAT IT IS IN PARK. FORCES ELECTRICAL TO STAY ON, AND SOMETIMES WILL NOT ENGAGE PARK SO VEHICLE CAN MOVE AS IF I'M NEUTRAL. HAS THUS FAR HAPPENED WITH VEHICLE STOPPED, BUT YOU CAN SOMETIMES SHUT OFF ENGINE AND EXIT VEHICLE WHEN IT IS NOT IN PARK AND CAN ROLL AGAINST YOU, OR ON KIDS EXITING ETC. VEHICLE ROLLED IN GARAGE AND STRUCK, AND COULD HAVE CRUSHED CHILD AGAINST DOOR.

WHEN THE VEHICLE IS WARM, THE TRANSMISSION APPEARS TO SLIP WHEN SHIFTING FROM 2ND TO 3RD GEAR. THE ENGINE WILL REV BETWEEN 500 TO 1000 RPM WHILE SHIFTING. DURING THIS TIME (HALF TO FULL SECOND) THE VEHICLE IS NOT ACCELERATING AND DOES NOT RESPOND TO THROTTLE INPUTS. THE VEHICLE HAS BEEN TAKEN INTO DEALERSHIPS 4 TIMES FOR THIS COMPLAINT. AT 35000 MILES (3RD DEALER VISIT), GM REPLACED THE VALVE ASSEMBLY. THE PROBLEM REOCCURRED AND GM IS ONLY OFFERING TO REPLACE THE SAME PART, OR EXTEND THE WARRANTY ON THE TRANSMISSION, BUT NOT BOTH. NO ONE AT THE DEALERSHIP OR GM TECHNICAL ASSISTANCE CENTER HAS ANY IDEA WHAT IS ACTUALLY WRONG AND IS NOT TAKING ANY STEPS TO FIND THE CAUSE OF THE ISSUE. THE SERVICE MANAGER HAS ADMITTED THAT THERE IS A PROBLEM, BUT GM DENIED HIM ANY HELP IN RESOLVING THE ISSUE.THEY HAVE SAID THAT THIS IS NOT A SAFETY ISSUE, BUT I DO NOT FEEL COMFORTABLE DRIVING A CAR THAT MAY BECOME UNRESPONSIVE TO ACCELERATOR PEDAL INPUT FOR A FULL SECOND. NOTE THAT THIS ISSUE IS STILL COVERED BY THE POWERTRAIN WARRANTY AT THIS TIME.

MY 2018 ACADIA KEEPS GIVING ERROR MESSAGE "SHIFT TO PARK" , IT HAS DRAINED MY BATTERY TWICE I HAD TO GET NEW ONE. IN ORDER TO SHUT OFF ERROR, I HAVE TO RESTART IGNITION AND MOVE SHIFTER TO DRIVE OR REVERSE SEVERAL TIMES BEFORE ERROR MESSAGE TO SHUT OFF. AT TIMES THE VEHICLE STILL THINKS IT IS ON AND THEN DRAINS BATTERY. I BROUGHT IT IN ON SEPTEMBER 2019 AND THE DEALERSHIP REPLACED THE HARNESS HOWEVER IT HAS STARTED AGAIN. MY WARRANTY IS ABOUT TO EXPIRE. IF THIS HAPPENS AGAIN I WILL NEED TO PAY OUT OF POCKET. I HAVE NOT RECEIVED ANY RECALL NOTIFICATIONS FROM GMC. THIS IS VERY FRUSTRATING AND IT IS A SAFETY HAZARD AS WE DON'T KNOW IF CAR IS ON PARK.

PUT CAR IN PARK AND PUSH BUTTON TO SHUT CAR OFF AND MOTOR TURNS OFF BUT IT'S IN ACCESSORY MODE AND THE DISPLAY MESSAGE SAYS TO SHIFT TO PARK. TAKES NUMEROUS TIMES TURNING CAR ON AND OFF AND MOVING THE SHIFT BUTTON AROUND BEFORE IT RECOGNIZES THAT THE CAR IS IN PARK. IT STARTED A MONTH AGE WHERE IT WOULD HAPPEN ONLY ONCE AND WHEN I TURNED THE CAR ON AND BACK OFF IT STAYED OFF WHICH MADE ME THINK IT WAS HUMAN ERROR. THIS LAST TIME IT TOOK ME AN HOUR BEFORE IT RECOGNIZED IT WAS IN PARK SEARCH THE INTERNET AND SEE OTHER PEOPLE HAVING THE SAME PROBLEM AND GMC IS AWARE BUT NO RECALLS.
