What 389 owners told NHTSA about the 2018 GMC Acadia Denali

I AM GETTING A ERROR MESSAGE "SHIFT TO PARK" EVEN WHEN THE VEHICLE IS CLEARLY IN PARK. IT DRAINS THE BATTERY BECAUSE YOU CAN'T SHUT OFF THE VEHICLE WITH THE MESSAGE. HAVE TO JIGGLE THE SHIFTER AFTER SEVERAL ATTEMPTS IT MAY CLEAR THE MESSAGE. HAD ONE TIME I GOT OUT WITH THE ERROR MESSAGE AND THE VEHICLE BEGAN TO ROLL WITH NO ONE IN IT EVEN THOUGH THE SHIFTING AREA SAID "P" FOR PARK. AND SITTING IN MY GARAGE WITH CAR RUNNING COULD NOT GET THE SHIFTER TO MOVE TO REVERSE, DRIVE, ANYTHING, HAD TO SHUT IT OFF 3 TIMES BEFORE IT WOULD REGISTER. HAVE HAD THE WIRING HARNESS ALREADY REPLACED.

ON DECEMBER 5TH 2019, I ARRIVED HOME FROM WORK TO TAKE MY SON TO HIS DR. APT. I PULLED INTO MY DRIVEWAY AROUND 10:30AM. I LEFT THE CAR ON SO MY SON WOULDN'T HAVE TO GO INTO A COLD CAR, BEING HE WAY SICK. I RAN INTO MY HOUSE WHERE MY MOTHER WAS WATCHING BOTH MY SONS. I SAID TO MY MOM, LET ME USE THE RESTROOM QUICKLY BEFORE I GET HIS COAT ON. I WAS NO MORE THAN 2 MINS. AS I STEPPED OUT THE BATHROOM, I HEAR MY HUSBAND SCREAMING FROM UP STAIRS THE CAR IS ON FIRE! HE COMES RUNNING DOWN THERE STAIRS AS FAST AS HE CAN, ALMOST INJURING HIMSELF BECAUSE HE DIDN'T SEE ME YET AND THOUGHT I WAS IN THE CAR! HE THEN SEES ME AND GRABS THE FIRE EXTINGUISHER. HE RUNS OUTSIDE TO TRY AND EXTINGUISH THE FIRE..AS I CALLED THE FRANKLIN SQUARE FIRE DEPARTMENT AND 911. BUT IN UNDER THE 5 MINS THE CAR WAS ENGULFED IN FLAMES! WE HAD TO THEN EVACUATE THE HOUSE BECAUSE THE GARAGE IS AN ATTACHED GARAGE AND THE CAR WAS IN THE DRIVEWAY OF THE GARAGE. MY POOR KIDS WERE FRIGHTENED FOR THEIR LIFE AS WE RUSHED THEM OUT THE HOUSE AS THEIR MOMMYS CAR WAS UP IN FLAMES..THEY WERE CRYING THEIR EYES OUT IN FEAR. THE FIRE CAUGHT ONTO THE TREE ON THE FRONT LAWN AS WELL AS DESTROYING THE GARAGE AND DRIVEWAY. I CRIED EXTENSIVELY THINKING OF THE WHAT IFS...WHAT IF I PUT MY SON AND I DIRECTLY INTO THE CAR, WITHOUT USING THE RESTROOM THAT DAY. WHAT IF THIS HAD OCCURRED WHEN I WAS DRIVING ON THE PARKWAY WITH MY WHOLE FAMILY IN THE VEHICLE. THIS VEHICLE WAS A DEATH TRAP THAT ALMOST TOOK MY LIFE AND MY FAMILY. WE FOUND THAT THEIR HAD BEEN A RECALL ON THE GMC ACADIA FOR THE 2017-2018 EDITIONS. I HAVING A 2018, WHERE WAS MY NOTIFICATION OF A RECALL? WHERE WAS MY LETTER..EMAIL..CALL FROM GM? I HAVE NUMEROUS FRIENDS THE RECOMMEND THE GMC ACADIA AS A GREAT FAMILY CAR. THEY ARE ALL NOW SCARED TO DEATH BECAUSE OF WHAT HAPPENED TO ME. NON FEEL SAFE USING THEIR VEHICLE NOW.

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.

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.

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.

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.

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.

NHTSA ODI 11282808

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

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.

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.

NHTSA ODI 11271454

SHIFT TO PARK ICON COMES UP AND WILL NOT LET ME TURN OFF VEHICLE. THIS IS DANGEROUS AND NEEDS TO BE RECALLED. AND TO TOP IT OFF, I SENT IT TO A GMC DEALER AND THEY TOLD ME THEY HAVE TO ORDER PARTS BUT SINCE GMC IS ON STRIKE THE PARTS WILL TAKE A LITTLE WHILE TO GET HERE.

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?

NHTSA ODI 11270613

WHEN VEHICLE IS IN PARK THE CAR IS NOT REALIZING AND IS ALARMING WITH A MESSAGE SHIFT TO PARK. I'VE READ THIS IS A COMMON PROBLEM IN 16-18 ACADIAS AND THIS IS A SAFETY ISSUE AS WELL WHEN I CAN NOT TURN THE VEHICLE OFF
