2018 GMC Acadia Complaint Log

CAR WARNS TO PUT IN PARK WHEN IT IS IN PARK. DEALER FIXED IT A YEAR AGO AND IT HAS STARTED AGAIN

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.

SHIFT TO PARK NOTICE. WHEN ATTEMPTING TO TURN OFF VEHICLE AND SHIFTED INTO PARK, VEHICLE WILL GIVE A WARNING THAT VEHICLE IS NOT IN PARK. AT THIS POINT I HAVE NO IDEA IF THE VEHICLE IS IN PARK OR NOT. NOT SURE IF I AM JUST RECEIVING A FAULTY NOTICE OR IS THE VEHICLE NOT IN PARK AND COULD ROLL CAUSING INJURY! THIS IS NOT A SAFE VEHICLE. GMC UNABLE TO REPAIR DUE TO NOT HAVING THE PART AVAILABLE. THIS MAY HAPPEN FOR TWO OR THREE TIMES. IT HAS HAPPENED THAT I HAVE HAD TO TURN MY CAR OFF AND BACK ON UP TO SEVEN TIMES BEFORE IT REGISTERED AS IN PARK.

WHEN I TURN THE CAR OFF I RECEIVE THE MESSAGE SHIFT TO PARK. THE CAR IS ALREADY IN PARK AND I HAVE TO SHIFT MULTIPLE TIMES FOR THE CAR TO REGISTER IT AS PARKED.

WE HAVE AN ISSUE WITH THE GEAR SHIFT, SINCE THREE WEEKS AGO WE CAN'T TURN OFF THE ENGINE AS A NORMAL PROCEDURE BECAUSE THE SENSOR OF THE GEAR SHIFT DOESN'T DETECT THE SHIFT IS IN 'P' PARKING, WE CONTINUALLY RECEIVE A MESSAGE FROM THE SCREEN. 'PUT YOUR SHIFT IN 'P', BUT IN THIS PRECISE MOMENT THE SHIFT WAS IN PARKING MODE, SO WE CAN'T TURN OF THE ENGINE. WE RECEIVE A NOTIFICATION FROM THE MECHANICAL WORKSHOP THAT THE ISSUE COULD BE THE ELECTRICAL HARNESS, BUT THEY DOESN'T GIVE US WHEN COULD BE CHANGED, SO RIGHT NOW WE HAVE MORE THAN TWO WEEKS WITHOUT USE THE VEHICLE, THEY DO NOT RECEIVE A OFFICIAL FEEDBACK FOR THE PLANT YET.

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.

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.

WHEN I TRY TO SHUT VEHICLE OFF IT SAYS SHIFT TO PARK. MY VEHICLE IS ALREADY IN PARK AND I CANNOT SHUT IT OFF. IT JUST CONTINUES DO DING AS WELL AND I CANNOT LOCK THE DOORS AND THE LIGHTS WILL NOT TURN OFF.

SHIFT TO PARK 2018 GMC ACADIA AWD ERROR MESSAGE SAYING VEHICLE ISN'T IN PARK; MULTIPLE ATTEMPTS TO MOVE SHIFT LEVER, TURN OFF AND ON, ETC FAIL TO TURN OFF THE ERROR MESSAGE SO THE CAR WILL COMPLETELY TURN OFF. CAR TURNS OFF BUT THE ALARM KEEPS BEEPING SAYING IT'S NOT IN PARK. VEHICLE HAS BEEN AT THE DEALER FOR OVER 2 WEEKS WITH NO, ZERO, DATE OF REPLACEMENT TO ARRIVE. VEHICLE IS OWNED (NO FIANCING, NO LEASE). PAID FOR A $50K VEHICLE THAT I CAN'T DRIVE. NOT SAFE, NOT USEABLE.

THE SHIFTER IS IN PARK WITH THE P LIT UP, BUT I CANNOT SHUT OFF MY CAR. A MESSAGE COMES ON THE SCREEN THAT SAYS SHIFT TO PARK THEN PUSH OFF. IT CONTINUES TO RUN UNTIL I TAKE IT OUT OF PARK AND PUT IT BACK IN.

WHEN PUSHING VEHICLE IGNITION BUTTON "START/STOP" TO TURN VEHICLE "OFF" IT WILL TURN THE ENGINE OFF BUT KEEP THE VEHICLE STILL "ON" USING THE BATTERY. IF I OPEN THE DOOR AND SHUT IT, THE HORN HONKS TO ALERT THAT THE VEHICLE IS STILL "ON" AND NOT COMPLETELY STOPPED. THE ONLY WAY TO GET THE IGNITION BUTTON TO ACKNOWLEDGE THE VEHICLE IS OFF IS BY JERKING THE GEAR SHIFT UNTIL THE GREEN LIGHT GOES TO "OFF". IT DOES NOT DO IT EVERY TIME I TURN THE VEHICLE OFF, BUT IT DOES IT ABOUT EVERY OTHER TIME. I WILL TAKE IT TO THE DEALERSHIP VERY SOON FOR THEM TO LOOK AT THIS ALSO.

AFTER SHIFTING MY ACADIA INTO PARK AND SHUTTING IT OFF, "SHIFT TO PARK" WARNING COMES US SOUNDING AN ALARM THAT WON'T GO OFF UNLESS I START THE CAR AND SHIFT IN AND OUT OF PARK SEVERAL TIMES. IT GETS HARDER TO GET THE WARNING TO GO AWAY EACH TIME I DRIVE IT. I HAVE HAD TO RESULT TO NOT DRIVING IT TO AVOID THE BATTERY DRAINING OR HAVING TO UNHOOK THE BATTERY. THE CAR ONLY HAS 19000 MILES SO THE DEALER IS WILLING TO REPLACE IT BUT THERE ARE NO PARTS AVAILABLE. ALSO, OTHERS HAVE MENTIONED THAT THE PROBLEM RETURNS EVEN AFTER THE REPAIR.

WHENEVER I SHIFT FROM DRIVER OR REVERSE INTO PARK MY CAR ISN'T REGISTERING THAT I SHIFTED TO PARK AND IF GIVING ME THE MESSAGE OF 'SHIFT TO PARK'. I HAD TO SHIFT FROM DRIVE TO PARK AT LEAST 4 TIMES TO BE ABLE TO GET MY CAR TO RECOGNIZE THAT MY CAR WAS IN PARK AND SO I COULD TURN OFF MY 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.

WHEN THE CAR IS SHIFTED INTO PARK, THE DASHBOARD SHOWS A WARNING THAT THE CAR IS NOT IN PARK. THE CAR THEN WON'T TURN OFF COMPLETELY.

THE SIX SPEED TRANSMISSION ALWAYS EXHIBIT BUCKING/HESITATION WHEN SHIFTING FROM 1ST GEAR TO 2ND GEAR. ALSO, WHEN SPEED BETWEEN 40MPH TO 50MPH, THE TRANSMISSION EXHIBIT SEVERE HESITATION TO DOWNSHIFT WHEN PRESS THROTTLE PEDAL. MOREOVER, THE TRANSMISSION EXHIBITS HARSHNESS WHEN DOWNSHIFT WHEN DECELERATING FROM 45MPH TO 0MPH.

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 VEHICLE IS SHIFTED TO PARK.

'SHIFT TO PARK' ERROR MESSAGE IS SHOWING WHEN MY VEHICLE IS ALREADY IN PARK AND I'M TRYING TO TURN THE VEHICLE OFF. I PURCHASED THIS VEHICLE LESS THAN A MONTH AGO AND IT CURRENTLY HAS 33K MILES ON IT. I'VE HAD TO TURN THE VEHICLE BACK ON SEVERAL TIMES TO GET THIS ERROR TO GO AWAY. WHEN THE MESSAGE FLASHES I'VE EVEN EXPERIENCED THE VEHICLE ROLLING INDICATING IT IS IN FACT NOT IN PARK ALTHOUGH THE SHIFTER IS IN PARK POSITION. THIS NEEDS TO BE RECALLED IMMEDIATELY AND I WILL ALSO BE CONSULTING AN ATTORNEY AS THIS IS A KNOWN ISSUE WITH NO CLEAR FIX (MANY PEOPLE WHO HAVE HAD THE SHIFTER REPLACED ARE HAVING THE SAME PROBLEMS AGAIN) AND THE PART THAT NEEDS TO BE REPLACED IS ON BACKORDER. PEOPLE'S VEHICLES LITERALLY CANNOT TURN OFF RESULTING IN BATTERIES DYING AMONG THE VERY OBVIOUS SAFETY CONCERNS. HOW IS THIS LEGAL?

I'M AFRAID ONE TIME IT WILL BE STUCK THERE PERMANENTLY.THIS APPARENTLY IS A KNOWN AND FREQUENT ISSUE AND GMC NEEDS TO DO A RECALL.

SHIFT TO PARK I SHIFT THE CAR INTO PARK AND TRY AND TURN THE CAR OFF AND IT STILL SAYS SHIFT TO PARK LIKE THE CAR ISNT IN PARK BUT IT IS. IT WONT ALLOW ME TO TURN THE CAR OFF. I HAVE TO SHIFT IT INTO DIFFERENT GEARS OR JIGGLE THE SHIFTER FOR IT TO REGISTER. I HAVE HAD TO RESORT TO REMOVING THE BATTERY CABLES OFF TO TURN IT OFF ONE TIME AS WELL. THE CAR WHEN IT DOES SHUT OFF FEELS LIKE THE TRANSMISSION ISNT FULLY ENGAGED.

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.

GMC ACADIA "SHIFT TO PARK". THE SUVS FAIL TO DETECT WHEN THE GEAR SHIFT LEVER IS MOVED TO PARK. THE DASH BOARD SHOWA A MESSAGE ON THE INSTRUMENT CLUSTERS THAT SAYS SHIFT TO PARK EVEN THOUGH THE GEAR SHIFT LEVERS ARE ALREADY IN PARK. IN ADDITION TO LOSING THE ABILITY TO SHUT OFF AND LOCK THE SUVS, I WAS UNABLE TO TURN THE SUV OFF AFTER ATTEMPTING TO DO SO SERVERAL TIMES.

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.

RECEIVE A SHIFT TO PARK ISSUE WHEN TRYING TO TURN OFF THE CAR. HAVE TO MOVE THE SHIFT TO DRIVE AND BACK TO PARK MULTIPLE TIMES BEFORE IT ALLOWS ME TO SHUT OFF THE CAR.

Component/System: Transmission selector / electrical system (“Shift to Park” defect) Yes, vehicle is available for inspection upon request. I own a 2018 GMC Acadia. Since I purchased the vehicle used in June 2019, the car has frequently displayed a “Shift to Park” message even when the vehicle is in park and the gear shifter is fully engaged. This message prevents the car from turning off completely, leaving electrical systems running, the ignition on, and draining the battery. This issue has persisted nearly daily for the past five years. I brought the vehicle to a GM dealership in September 2020, while it was still under factory warranty, but the problem was not diagnosed or repaired at the time. The dealership could not reproduce the issue, but it continued regularly afterward. I am now paying nearly $900 out of pocket to have it repaired. Safety Risks: The vehicle does not fully shut down, increasing risk of electrical malfunction or battery failure. I am often unsure whether the car is truly “off,” which could pose a fire hazard or lead to the car rolling unexpectedly if the system misreads the gear position. This defect has also caused me to get stuck in unsafe areas, repeatedly turning the car off and on, jiggling the shifter until the system registers park. The constant battery drain has left me stranded with a dead vehicle multiple times. Reproduction / Confirmation: The issue has been reproduced by an independent repair shop and will be fixed at my expense next week. A GM dealership inspected it in 2020 but failed to diagnose or confirm the issue at that time. Inspection: The vehicle has been inspected by a GM-authorized service center. Not inspected by police or insurance representatives. Warning Messages or Symptoms: The “Shift to Park” message appears on the dashboard even after the vehicle is correctly shifted into park. This began shortly after purchasing the vehicle in June 2019, worsened over time, & still has the inability to turn off properly.

WHEN I TRY TO SHUT OFF IGNITION I GET A WARNING ON THE DASH THAT SAYS TO PUT VEHICLE INTO PARK BEFORE SHUTTING THE VEHICLE OFF EVEN THOUGH THE VEHICLE IS IN PARK ALREADY. I HAVE TO SHIFT IN AND OUT OF PARK OR RIDE AROUND AGAIN AND THEN TRYING PARKING AGAIN TO GET IT TO SHUT OFF. ONCE I EVEN LEFT IT RUNNING AND WENT INTO THE STORE BECAUSE I COULD NOT GET THE VEHICLE TO SHUT OFF DUE TO IT THINKING IT WAS NOT IN PARK AND IT WAS.

THE VEHICLE KEEPS SAYING "SHIFT INTO PARK" WHEN PARKED. CAN NOT CORRECTLY SHUT THE VEHICLE OFF OR LOCK THE DOORS ALL THE DASH STAYS LIT UP. MUST RUN THROUGH THE GEARS SEVERAL TIMES. TURNING IT OFF AND ON UNTIL IT GOES AWAY.

WHILE STATIONARY, INSTRUMENTS SHOW A SHIFT TO PARK MESSAGE, EVEN THOUGH THE CAR WAS IN PARK. ACADIA WOULD NOT FULLY TURN OFF UNTIL THIS MESSAGE IS NOT PRESENT. THE ONLY WAY FOUND TO HAVE THE MESSAGE CLEAR IS TO CONTINUALLY SHIFT FROM DRIVE TO PARK UNTIL IT RECOGNIZES THAT THE CAR IS INDEED IN PARK. THIS HAPPENS REPEATEDLY - 8 OUT OF 10 TIMES I DRIVE MY CAR.

CAR WILL NOT RECOGNIZE I'VE SHIFTED TO PARK WHEN I TURN OFF THE VEHICLE. IT SAYS SHIFT TO PARK WHEN I ALREADY HAVE, AND I HAVE TO START THE CAR AND SHIFT AGAIN OVER AND OVER TO PARK FOR IT TO WORK. VERY CONCERNED ABOUT SAFETY.

WHEN THE CONTACT TURNED OFF THE VEHICLE AND REMOVED THE KEY FROM THE IGNITION, THE VEHICLE'S WARNING SENSOR WENT OFF, THE RADIO REMAINED ON, AND THE AUTOMATIC DOOR LOCKS FAILED.

THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 21,000.

GMC ACADIA WILL NOT REGISTER WHEN THE DRIVER SHIFTS THE GEARS INTO PARK. AN ERROR MESSAGE 'SHIFT TO PARK' IS SHOWN ON THE DASHBOARD EVEN THOUGH THE GEAR IS IN PARK. THE DRIVER IS UNABLE TO TURN THE CAR OFF BECAUSE OF THE ERROR MESSAGE. IT TAKES SEVERAL TURNS OF SWITCHING THE CAR ON AND OFF AND FLIPPING THROUGH ALL THE GEARS IN ORDER FOR THE MESSAGE TO DISAPPEAR SO THAT THE CAR TURNS OFF. THE CAR WAS TAKEN TO THE DEALER ON JUNE 26 FOR REPAIRS AND HAS BEEN SITTING THERE OVER A MONTH BECAUSE THEY ARE UNABLE TO CORRECT THE ISSUE.

ON SEPARATE OCCASIONS, BOTH PARKED TURNED OFF AND RUNNING DOWN HIGHWAY, THE DASH LIGHTS LIT UP AND ALARMS CHIMED. CAR WOULDN'T START, NO COLD A/C. THE "SERVICE POWER STEERING" MESSAGE DISPLAYED. CAR DIDN'T TURN AS WELL. COULDN'T SHIFT. AFTER DOING SO FOR A ABOUT 2-3 MINUTES IT WOULD GO BACK TO NORMAL. THE ATTACHED PHOTO WAS WHILE DRIVING DOWN THE ROAD YOU'LL NOTICE IT DOESN'T MEASURE ANY RPM'S HOWEVER THE CAR IS MOVING ABOUT 40MPH

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT WHILE ATTEMPTING TO TURN THE VEHICLE OFF WITH THE START/OFF BUTTON, THE VEHICLE CONTACT WAS ALERTED IN THE MESSAGE CENTER OF THE VEHICLE TO PLACE THE VEHICLE IN THE PARK. THE CONTACT STATED THE GEAR SHIFT LEVER WAS ALREADY IN THE PARK POSITION WHEN THE MESSAGE WAS DISPLAYED. THE VEHICLE WAS TAKEN TO HERTRICH BUICK GMC LOCATED AT 26953 SUSSEX HWY, SEAFORD, DE 19973, 302-629-9144 TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE IGNITION NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, HOWEVER, THE FAILURE PERSISTED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 31,000. THE VIN WAS NOT AVAILABLE.

AFTER PARKING, MY ACADIA WOULD NOT SHUT OFF COMPLETELY. A MESSAGE CAME ON THE DASH, 'ACTION REQUIRED, SHIFT TO PARK'. A CONSTANT CHIME WAS SOUNDING ALSO. I RESTARTED THE CAR, SHIFTED OUT OF PARK, BACK INTO PARK, TRIED TO SHUT OFF AGAIN...SAME THING....4X'S!!! I WENT RIGHT OVER TO THE DEALER WHERE I BOUGHT MY CAR AND EXPLAINED WHAT WAS HAPPENING ( COULDN'T SHUT OFF THERE EITHER). SERVICE MANAGER KNEW IMMEDIATELY WHAT THE PROBLEM WAS BUT SAYS THE PART (GEAR SHIFT) IS ON BACKORDER AND HAS NO IDEA FOR HOW LONG!!! WHAT??? WHY ISN'T THIS A RECALL? I'VE READ QUITE A FEW OF THIS SAME COMPLAINT SO I CAN'T UNDERSTAND HOW THIS ISN'T A RECALL ALREADY ESPECIALLY IF THE GEAR SHIFT REQUIRED TO FIX THE PROBLEM IS ON BACKORDER, IT'S OBVIOUSLY A BIGGER ISSUE THEN 1 OR 2. SO FOR NOW , I JUST HAVE TO WAIT AND 'KEEP PLAYING WITH THE GEAR SHIFTER UNTIL IT GOES OFF' AS I WAS TOLD UNTIL THE PART COMES IN! HOW CRAZY IS THIS

I purchased vehicle in 2018 and by 2019 it started showing a message that said error Shift need to park but I was parked and gear in parking mode .I reported to dealer but said they couldn't help me since my warranty was over due to my job I drive alot so I was over the mileage. So they itbwouldnt be covered since then it goes off and on same message and now I can't get off car until it goes off because I'm afraid to let go of brake if the parking gear don't work. I reported to dealer in time to get assistance but they just brushed it off blamed me for the mileage Maybe causing it but I see here I'm not the only one complaining about message "Shift".

WATER LEAKING IN THREW BACK WINDOWS, SIDE WALLS , WATER COMING IN THERE PLASTIC IN DOORS BOTH FRONT AND BACK, WATER COMING IN BACK UP UNDER HEAD LINER. THIS ALL HAPPENING AFTER RAINFALL AND THE CAR WAS PARKED IN DRIVE. THIS CAR ONLY HAS 8,000 MILES ON IT PURCHASED BRAND NEW IN OCTOBER 2018 OFF SHOW ROOM FLOOR, I AM THE ONLY OWNER. I HAVE PICTURES TO SUPPORT ALL OF THIS AS WELL, INCLUDING WATER DAMAGE.

AUTO DOES NOT RECOGNIZE THAT TRANSMISSION IS IN PARK.

"SHIFT TO PARK" ERROR 90% OF THE TIME WHEN I ATTEMPT TO SHUT THE VEHICLE OFF. IT IS IN PARK AND IT'S NOT RECOGNIZED AS BEING IN PARK. IT CAN TAKE ME ANYWHERE FROM 30 SECONDS TO 5 MINUTES TO JIGGLE IT THE RIGHT WAY TO GET IT TO REGISTER. PROBLEM IS UNTIL IT DOES REGISTER IN PARK I CAN'T SECURE THE VEHICLE. AND IT DINGS NONSTOP DRAINING THE BATTERY. I UNDERSTAND GM IS AWARE OF THE ISSUE AND DOESN'T HAVE A FIX. IT NEEDS A NEW TRANSMISSION IN MY OPINION. I'M STUCK IN A LEASE PAYING FOR A CAR THAT ISN'T SAFE FOR ME. IT JUST STARTED 6 DAYS AGO AND HAS ALREADY OCCURRED MORE THAN 2 DOZEN OCCASIONS.

MY CAR KEEPS GIVING NOTICE OF IT NOT BEING IN PARK, WHEN ITS CLEARLY SHIFTED INTO PARK. IT WONT SHUT DOWN, LET YOU LOCK DOORS. JUST BEEPS UNTIL IT FINALLY REALIZES ITS IN PARK. EVEN AFTER CONTINUOUSLY RE SHIFTING INTO PARK. WORSE IN THE SUMMER MONTHS. IT NEEDS TO BE FIXED AS MANY OTHERS ARE HAVING THE SAME ISSUE! *TR

WHEN THE CAR IS SHIFTED INTO PARK, THE DASHBOARD SHOWS A WARNING THAT THE CAR IS NOT IN PARK. I HAVE TO MOVE THE SHIFTER BACK AND FORTH BEFORE THE CAR REGISTERS THAT IT'S IN PARK. HAPPENS ON NEARLY EVERY OCCASION THAT I TURN MY CAR OFF.

1* PURCHASED MARCH 2018 (ACADIA DENALI) SINCE AUGUST 2018 IN MOTION WHEN I ACCELERATE IT SOUNDS LIKE A LOUD LAWNMOWER & CRACKLING SOUND IN REAR MUFFLER AREA. TOOK IT CHEVY PLACE IN GLENPOOL, OK. THEY COULDN'T FIND ANYTHING. 2* ON 2 OCCASSIONS, IN MOTION, THE CAR ACCELERATED WITH A LOUD NOISE & AS IF IT WERE GETTING POWER & NOT MOVING THEN JERKS & SPEEDS UP ABOUT 15MPH FASTER & I COULDN'T STOP IT. I KEPT SLAMMING ON MY BREAKS, BUT THE BREAK WOULD ONLY GO IN SO FAR. I WAS FRIGHTENED WITH MY 2 YOUNG BOYS IN CAR SCREAMING. IT'S LIKE RIDING A HORSE & IT TAKES OFF & YOU CAN'T CONTROL IT. 3* ON ABOUT 8 OR 9 OCCASSIONS STATIONARY I GET OUT OF MY CAR & IT MAKES A REALLY LOUD ANNOYING SOUND LIKE A MACHINE/ROBOT POWERING DOWN. MY KIDS ALWAYS SAY, IT'S GOING TO BLOW UP 4* THE MOST ANNOYING, FOR PAST MONTH...STATIONARY, EVERY SINGLE DAY & TIME I TURN MY IGNITION OFF. IT HAS LOUD BEEPING SOUND & CHECK REAR SEAT FLASHING ON SCREEN THEN SHIFT INTO PARK FLASHES. THIS OCCURS EVERY SINGLE TIME I TURN MY CAR OFF. SOMETIMES I HAVE TO JUST LET IT GO ON ALL DAY BECAUSE I CAN'T GET IT STOP. I TURN CAR ON & OFF SHIFT BACK & FORTH & IT STILL WILL NOT GO OFF. SOMETIMES IT DOES AFTER LONG PERIODS OF TIME. I DON'T HAVE TIME TO STRUGGLE WITH GETTING A CAR INTO PARK EVERY SINGLE TIME I TURN MY IGNITION OFF. I HAVE TO BEAT IT FORWARD HARD WITH MY HAND TO THE POINT MY WRIST IS BRUISED. NOW I HAVE TO USE MY FOOT TO KICK GEAR SHIFTER INTO PARK. I'M AFRAID T'S GOING TO ROLL OUT & OR DOWN AND HIT SOMETHING, SOMEONE OR EVEN ONE OF MY CHILDREN. WHICH WOULD NOT BE GOOD. I'VE SEEN SEVERAL OF SAME COMPLAINTS. THIS REALLY NEEDS TO BE INVESTIGATED & RECALLED ASAP. MY ELDERLY MOTHER HAD TO CALL MY BROTHER TO ANOTHER PART OF TOWN TO BEAT THE GEAR SHIFT INTO PARK. THIS CAR WAS BRAND NEW & I SHOULDN'T HAVE ANY OF THE ABOVE MENTIONED ISSUES. IT'S FRUSTRATING THINKING GMC WAS TOP OF THE LINE & IT'S NOT.
