2018 GMC ACADIA Complaints

I PUT THE CAR IN PARK, BUT THE INSTRUMENT PANEL READS "SHIFT TO PARK." THE ENGINE TURNS OFF, BUT THE ELECTRICAL SYSTEM STAYS ON BECAUSE THE CAR DOESN'T THINK IT'S ACTUALLY IN PARK. I HAVE TO TURN THE ENGINE BACK ON, SHIFT TO ANOTHER GEAR, SHIFT BACK TO PARK, AND TURN THE ENGINE OFF TO SEE IF IT REGISTERS THAT THE CAR IS IN PARK. I'VE HAD TO DO THIS SEVERAL TIMES BEFORE THE CAR ACTUALLY REGISTERS THAT ITS IN PARK AND WILL COMPLETELY TURN OFF.

RECEVIED "ACTION REQUIRED - SHIFT TO PARK" MESSAGE ON INSTRUMENT PANEL SCREEN. MOTOR TURNS OFF BUT VEHICLE STAYS IN ACCESSORY MODE AND CHIMES CONTINUOUSLY. DEALER REPLACED WIRING HARNESS THAT PROMISED TO FIX THE PROBLEM, WENT AWAY FOR 1 MONTH AND CAME BACK. JIGGLING THE SHIFTER OR FLICKING THE SHIFTER BUTTON IS THE ONLY WAY IT WILL GO AWAY.

EXPERIENCED THE "VEHICLE NOT IN PARK " WHEN SHIFTER WAS IN PARK. ENGINE WOULD NOT TURN OFF BECAUSE ELECTRICAL SWITCH DID NOT RECOGNIZE THE VEHICLE WAS IN PARK. AFTER MANY TRIES I WAS ABLE TO TURN VEHICLE OFF. HAD VEHICLE SERVICED AND SHIFTER WAS REPLACED (3 WEEKS AGO ). TODAY SHIFTER FROZE IN PARK YET CONSOLE INDICATED VEHICLE WAS IN DRIVE. DID NOT REMOVE FOOT OFF OF BRAKE BECAUSE VEHICLE WOULD MOVE FORWARD BECAUSE IT WAS IN GEAR. COULD NOT SHUT OFF VEHICLE BECAUSE IT IS A PUSH BUTTON START/STOP AND FOOT MUST BE OFF BRAKE TO STOP ENGINE. CALLED DEALER FOR HELP. FINALLY WE PUT EMERGENCY BRAKE ON AND PUSHED STOP BUTTON. THE ENGINE TURNED OFF BUT ELECTRICAL SYSTEM WAS STILL ON. HAD VEHICLE TOWED TO DEALER. THEY WILL ADVISE IN A WEEK OR SO THEY ARE SHORT HANDED.

THE SHIFT TO PARK ACTION REQUIRED KEEPS POPPING UP WHEN I GO TO TURN MY CAR OFF. THE CAR WILL BE IN PARK. I WILL HAVE TO TURN THE CAR ON AND OFF MULTIPLE TIMES BEFORE THE NOTIFICATION GOES AWAY AND THAN IM ABLE TO GET OUT OF THE CAR.

MY 2018 GMC ACADIA SLT-1 HAS BEEN HAVING ACCELERATION ISSUES LIKE SHUDDERING AND OR FEELS LIKE A FULL LOSS OF POWER , WITH NO CHECK ENGINE LIGHT. I'VE TAKEN IT INTO THE DEALERSHIP TWICE FOR THIS PROBLEM . I'VE ONLY TAKEN IT IN THIS 2ND TIME BECAUSE IT GOT WORSE AND SCARED ME THAT IT WOULD DIE ON THE HIGHWAY. IT ALSO HAS HAD TO HAVE THE BATTERY CHARGED 3 TIMES IN A COUPLE OF WEEKS , YET THE DEALER SAYS THE BATTERY CHECKS GOOD. AT THE LEAST I BELIEVED SINCE ITS UNDER WARRANTY THEY WOULD CHANGE THE BATTERY IN THE CASE THE COMPUTER IS CAUSING ISSUES BASED ON BATTERY VOLTAGE. THE ALTERNATOR IS WORKING , BUT WITH ONLY 29K MILES NONE OF THIS BATTERY NOR ACCELERATION SHUDDER AND STUMBLE LIKE ITS GOING TO DIE SHOULD BE ACCEPTABLE.

VEHICLE STATES "ACTION REQUIRED - SHIFT TO PARK" EVEN THOUGH VEHICLE IS IN PARK. ACCESSORIES STAY ON AND VEHICLE CONTINUOUSLY SOUNDS WARNING CHIME. THIS PROBLEM OCCURS EVERY TIME THE VEHICLE IS SHIFTED TO PARK AND ENGINE IS SHUT DOWN.

VEHICLE WILL NOT SHUT OFF DUE TO A SHIFT TO PARK MESSAGE WHEN THE SHIFTER IS ALREADY IN THE PARK POSITION.

GMC ACADIA IS PLACED IN "PARK," CLEARLY SHOWN ON THE DASH BOARD WITH THE "P" HIGHLIGHTED RED. WHEN THE POWER BUTTON IS PRESSED, A "SHIFT TO PARK" ALERT POPS UP AND WILL NOT ALLOW ME TO LEAVE THE CAR. THIS CAUSED ME TO BE LATE TO WORK THIS MORNING. THEN TONIGHT, AFTER WORKING A 12 HOUR SHIFT AT THE HOSPITAL ON THANKSGIVING, I HAD TO SIT IN MY GARAGE FOR 20 MINUTES TRYING TO TURN MY VEHICLE OFF.

THE VEHICLE WAS STATIONARY AND DID NOT ALLOW ME TO TURN THE POWER OFF. SHIFT TO PARK MESSAGE WOULD NOT GO AWAY EVEN THOUGH THE VEHICLE WAS CLEARLY IN PARK. I HAD TO TRY 10-15 TIMES TO PUT THE VEHICLE IN OTHER GEARS AND PARK AGAIN AND TURNING ON AND OFF UNTIL IT EVENTUALLY TURNED OFF. THIS HAS HAPPENED SEVERAL TIMES AND IF I JUST LEAVE IT WITH THE MESSAGE THERE THE CAR EVENTUALLY DRAINS MY BATTERY. IT HAS BEEN HAPPENING FOR A WEEK DURING SEVERAL DIFFERENT OCCASIONS AND AM CONCERNED IT COULD DRIVE AWAY ON ITS OWN IF IT HAPPENS AGAIN AND I CAN'T GET THE MESSAGE TO TURN OFF. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

'ACTION REQUIRED SHIFT TO PARK' - MESSAGE. STATIONARY. THE CAR IS IN PARK! BELLS SOUND. DOORS LOCK. BATTERY DRAINS. HUNDREDS OF OTHER FOLKS HAVE REPORTED THE SAME ISSUE ONLINE. PLEASE RECALL THIS CAR, DANGEROUS AND I HAVE KIDS.
