2018 GMC Acadia

ONE DAY MY CAR STARTED TELLING ME SHIFT TO PARK WHILE IT WAS IN PARK. AS THE DAY PROGRESSED IT BECAME WORSE AND WORSE. RESULTING IN THE CAR NOT SHUTTING OFF. PUTTING IT INTO GEAR AND BACK TO PARK WAS NOT HELPING. THE LAST TIME IT TOOK NEARLY 30 MINUTES BEFORE I COULD GET THE CAR TO SHUT DOWN COMPLETELY AS IT KEPT STARING SHIFT TO PARK. CAR WAS NOT MOVING HAD ONLY GONE WITHIN CITY LIMITS WITH MAX SPEEDS OF 45MPH.

WHEN TURNING OFF THE VEHICLE, A WARNING MESSAGE COMES ON SAYING "SHIFT TO PARK" EVEN THOUGH THE VEHICLE IS IN PARK. THE SHIFTER READS PARK AND SO DOES THE DASH. VEHICLE IS UNABLE TO BE COMPLETELY TURNED OFF OR LOCKED WITH THIS MESSAGE APPEARING. IT REQUIRES TURNING VEHICLE ON AND OFF, MOVING SHIFTER IN AND OUT OF PARK, JIGGLING SHIFTER BUTTONS, ETC. THIS CAN TAKE ONE TRY OR MULTIPLE TRIES. I JUST HAD THIS FIXED BY THE DEALERSHIP (REPLACED SHIFT CONTROL) AND WAS DISAPPOINTED TO FIND THAT THIS IS A KNOWN ISSUE, AFFECTING MANY VEHICLES AND IT IS STILL THE RESPONSIBILITY OF THE VEHICLE OWNER TO PAY FOR THE EXPENSE IF THE BUMPER TO BUMPER WARRANTY IS EXPIRED. THE SHIFTER RUNS THE POWER TRAIN! WHY IS THIS NOT UNDER THE POWER TRAIN WARRANTY AND WHY IS THIS NOT A RECALL? NOW, IN RESEARCHING, I'M SEEING THAT MANY HAVE HAD IT HAPPEN AGAIN AFTER THE ISSUE HAS BEEN "FIXED". DEALER TECH NOTES TSB 19-NA-206 IN HIS REPORT.

WHEN SHUTTING THE ACADIA OFF IT PROMPTS A MESSAGE SAYING MUST BE IN PARK. IT IS IN PARK BUT COMPUTER IS NOT RECOGNIZING IT. THIS FORCES YOU TO LEAVE CAR RUNNING. IF YOU DONT THEN YOUR BATTERY WILL GO DEAD. WHEN SPEAKING TO LOCAL DEALERSHIP THEY ARE AWARE OF ISSUE BUT DONT KNOW ANYTHING TO RESOLVE IT. CUSTOMERS SHOULDN'T HAVE TO PAY FOR THIS SINCE IT'S A SAFETY ISSUE.

WHEN PUTTING MY VEHICLE IN PARK AND PRESSING THE ENGINE OFF BUTTON, I GET AN ERROR MESSAGE "SHIFT TO PARK", AND THE VEHICLE BEEPS AND WILL NOT TURN OFF THE ELECTRICAL, BUT THE CAR IS ALREADY IN PARK. I AM UNABLE TO TURN OFF MY VEHICLE COMPLETELY. I HAVE TO PRESS START AGAIN AND PUT THE CAR IN REVERSE AND BACK TO PARK, SOMETIMES MULTIPLE TIMES IN ORDER FOR THE VEHICLE TO REGISTER THAT IS IN PARK AND ALLOW ME TO SHUT OFF MY VEHICLE COMPLETELY. I AM CONCERNED THAT THE VEHICLE MAY NOT ACTUALLY BE IN PARK WHEN I PUT IT IN PARK. I DO NOT WANT IT TO ROLL DOWN A HILL AND I WANT TO BE ABLE TO TURN OFF MY CAR WITHOUT BEING CONCERNED IT WILL CONTINUE TO RUN ELECTRICAL AND KILL MY BATTERY.

THE VEHICLE WOULD DISPLAY A DASHBOARD WARNING "SHIFT TO PARK." EVERY TIME THE VEHICLE WAS PUT INTO "PARK" THE VEHICLE WOULD NOT REGISTER THAT IT WAS IN PARK. THIS WOULD PREVENT THE VEHICLE FROM BEING TURNED OFF. A DRIVER WOULD THINK THE VEHICLE WAS IN PARK, AND TAKE THEIR FOOT OFF THE BRAKE, BUT THE VEHICLE WOULD NOT REGISTER IT WAS IN PARK AND WOULD DISPLAY A WARNING ON THE DASH "SHIFT TO PARK." YOU WOULD THEN HAVE TO SHIFT BACK AND FORTH, FROM PARK TO REVERSE OR DRIVE AND THEN BACK INTO PARK FOR THE VEHICLE TO FINALLY REGISTER IT WAS IN PARK. THIS WOULD OCCUR WHILE THE VEHICLE WAS STATIONARY AND SITTING ANYWHERE YOU WOULD PARK THE CAR.

WHEN PUTTING MY VEHICLE IN PARK AND PRESSING THE ENGINE OFF BUTTON, I GET AN ERROR MESSAGE "SHIFT TO PARK", AND THE VEHICLE BEEPS AND WILL NOT TURN OFF THE ELECTRICAL, BUT THE CARE IS ALREADY IN PARK. I AM UNABLE TO TURN OFF MY VEHICLE COMPLETELY. I HAVE TO PRESS START AGAIN AND PUT THE CAR IN REVERSE AND BACK TO PARK, SOMETIMES MULTIPLE TIMES IN ORDER FOR THE VEHICLE TO REGISTER THAT IS IN PARK AND ALLOW ME TO SHUT OFF MY VEHICLE COMPLETELY. I AM CONCERNED THAT THE VEHICLE MAY NOT ACTUALLY BE IN PARK WHEN I PUT IT IN PARK. I DO NOT WANT IT TO ROLL DOWN A HILL AND I WANT TO BE ABLE TO TURN OFF MY CAR WITHOUT BEING CONCERNED IT WILL CONTINUE TO RUN ELECTRICAL AND KILL MY BATTERY.
