2018 GMC Acadia Complaint Log

THIS VEHICLE HAS ALWAYS SINCE WE BOUGHT IT GAVE US TREMENDOUS PROBLEMS WHILE DRIVING DURING A SNOWY DAY. BRAKES TYPICALLY DO NOT WORK, AT TIMES EVEN GOING THROUGH A RED LIGHT AND THANKFULLY NOT BEEN IN AN ACCIDENT. RECENTLY, THE STABILITY CONTROL SYSTEM AND THE ANTILOCK BRAKING SYSTEM STOPPED WORKING WHILE UNDER A SNOW STORM. UNFORTUNATELY, WE TOOK IT TO THE NEAREST DELEARSHIP TO GET IT FIXED AND WE WERE TOLD THAT THE PROBLEM WAS DUE TO THE SNOW, BUT AFTER THE SNOW EVERYTHING WAS GOOD. UNFORTUNATELY, PEOPLE DO NOT HAVE THE MONEY TO PAY FOR A VEHICLE AND HAVE IT PARKED DURING THE WINTER, THAT IS WHAT IS HAPPENING TO US. BECAUSE NOR THE DEALERSHIP OR GMC HAS DONE ANYTHING TO HELP. THIS HAS BEEN REPORTED SINCE DECEMBER 2018, THE VEHICLE HAS 34500 MILES ON IT AND IS RELATIVELY NEW NOW, BUT WE SHOULD NOT HAVE THESE ISSUES. IT IS OF OUR KNOWLEDGE THAT MANY PEOPLE WHO BOUGHT THIS VEHICLE HAVE THE SAME ISSUES. IT WOULD BE GOOD IF THEY ACCEPT THESE VEHICLES HAVE ISSUES AND CORRECT THEM PRIOR TO PROMOTING AND SELLING TO CUSTOMERS. SINCE THEY DID NOT CORRECT THESE ISSUES PRIOR TO SOME INDIVIDUALS TO PURCHASE THE VEHICLE, THEY SHOULD WORK ON A SOLUTION VIA A RE-CALL TO AVOID ANY INJURIES TO FAMILIES OF THEIR VEHICLE'S OWNERS.

PLACE SHIFTER IN "PARK", TURN OFF ENGINE, AND GET "SHIFT TO PARK" MESSAGE ON CONSOLE. WHILE MESSAGE IS DISPLAYED, THE CAR CONSTANTLY BEEPS, WARNS, LIGHTS NOT TURNING OFF. HAVE TO START THE ENGINE BACK UP, AND PLACE THE SHIFTER INTO DRIVE AND THEN BACK TO PARK. SOMETIMES HAVE TO DO THIS 5-10 TIMES IN ORDER FOR THE CAR TO TURN OFF. THIS FIRST HAPPENED AT 11K MILES (UNDER WARRANTY) AND DEALERSHIP FIXED. I AM NOW AT 16K MILES AND IT IS HAPPENING AGAIN (OUT OF WARRANTY THIS TIME).

VEHICLE WHEN PUT IN PARK DOES NOT SHUT OFF. TOOK TO HILLSDALE GMC 1/13/20 AND IT WAS OKAY FOR AWHILE. THIS SAME PROBLEM STARTED ABOUT 3 MO AGO AGAIN. PUT IN PARK WILL NOT SHUT OFF. YOU MAY HAVE TO RESTART, PULL INTO GEAR, BACK TO PARK, OVER AND OVER! VERY ANNOYING ESPECIALLY IF YOU HAVE AN APPOINTMENT!

THE ACADIA HAS 23,700 MILES ON AND THE TIRES ARE WEARING OUT. NEW TIES SHOULDN'T BE NEEDED UNTIL 60,000 MILES. THIS IS A LOT OF DIFFERENCE IN WHAT SHOULD BE OBTAINED BY THESE TIRES.

Shift to park issue. Vehicle appears to be in park but message appears. You have to continuously wiggle shifter and shut car off and off until it registers it is in park. I have no way of knowing if vehicle is truly in park or not. For safety reasons I cannot park in an incline due to concerns the vehicle will roll backwards. Several TBS bulletins have been issued by GMC on this known issue and they deny any responsibility of fixing the situation with a recall. The NHTSA needs to step in and investigate and require GMC to remedy this dangerous defect

CAR DISPLAYS 'SHIFT TO PARK' MESSAGE AFTER TRANSMISSION GEAR SELECTOR HAS BEEN PLACED IN PARK. CAR WILL NOT TURN OFF AND THE TIRES ROLL FREELY. AFTER NUMEROUS ATTEMPTS OF SHIFTING IN AND OUT OF PARK THE CAR WILL FINALLY RECOGNIZE THAT IT IS IN PARK AND ALLOW YOU TO TURN OFF THE VEHICLE AS WELL AS LOCK THE TRANSMISSION.

I WAS GETTING A SHIFT TO PARK ERROR MESSAGE WHEN PUTTING MY ACADIA IN PARK. I HAD IT REPAIRED ON 08/18/2018. THE SAME PROBLEM CAME UP AGAIN AND WAS REPAIRED TODAY 10/19/2020. THIS IS A SAFETY ISSUE AND VERY FRUSTRATING. MY WARRANTY EXPIRES ON 12/14/2020 AND BECAUSE THERE ARE SO MANY COMPLAINTS ON THE GM AUTHORITY WEBSITE THIS SHOULD BE A RECALL SO MYSELF AND OTHERS ARE NOT STUCK WITH PAYING FOR SOMETHING THAT IS NO LONGER UNDER WARRANTY. THIS HAPPENS WHEN A VEHICLE IS PUT INTO PARK AND THEN THIS SHIFT TO PARK ERROR MESSAGE COMES UP. SOMETIMES YOU CANNOT EVEN SHUT THE VEHICLE OFF. BOTH REPAIRS INVOLVED REPLACING THE SHIFTER ASSEMBLY. THIS IS A GM PROBLEM AND SHOULD THEY SHOULD ISSUE A RECALL.

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT THE VEHICLE WAS STARTED REMOTELY WHILE STILL IN PARK, HOWEVER IT INDEPENDENTLY SHIFTED OUT OF PARK AND INTO REVERSE. THE CONTACT STATED THAT THE VEHICLE TRAVELED ACROSS THE YARD ONTO THE MAIN ROAD AND CRASHED INTO A BUILDING. A POLICE REPORT WAS NOT FILED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT AUTOBODY SHOP BUT THE FAILURE WAS NOT DIAGNOSED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 16,972.

WHEN THE VEHICLE NEEDS TO BE SHIFTED TO "PARK", THE CAR NOTIFIES YOU ON SCREEN "SHIFT TO PARK" AND THEN BECOMES STUCK AND YOU HAVE TO KEEP WIGGLING, TRYING TO GET IT TO ACTUALLY PARK UNTIL THE NOTICE GOES AWAY. IT HAPPENS AT RANDOM AND HAS BEEN GOING ON FOR THE LAST TWO WEEKS. THERE SEEMS TO BE NO RECALL, YET THE 2017 2018 MODELS ARE ALL HAVING THIS SAME ISSUE AND THERE IS NO RECALL YET. THIS IS A HUGE SAFETY ISSUE AND WE ARE NOW BEING RESPONSIBLE FOR THE CHARGES TO HAVE IT BEING FIXED. THIS SHOULD NOT BE MY RESPONSIBILITY AS IT IS HUGELY AWARE TO ALL THE DEALERSHIPS AND THERE ARE COURT CASES BEING FILED BECAUSE OF THIS.

SHIFT TO PARK ISSUE NOT ENGAGING PROPERLY RESULTING IN LIGHTS AND ALARM STAYING ON AND NOT ALLOWING DOORS TO LOCK. OCCURS FREQUENTLY.

SINCE THE BEGINNING OF OCTOBER, THERE ARE TIMES THAT THE CAR DOESN'T REGISTER THAT IT IS IN PARK. WHEN THE CAR IS TURNED OFF, THERE IS AN ALERT THAT COMES UP ON THE DISPLAY SAYING TO PUT THE VEHICLE IN PARK. IT ISN'T EVERY TIME THE ENGINE IS TURNED OFF, BUT IT CAN SOMETIMES TAKE UP TO FOUR OR FIVE TRIES TO GET THE CAR TO REGISTER THAT IT IS IN PARK. I SHIFT TO PARK, TURN THE CAR OFF, GET THE ALERT. SO I TURN THE CAR BACK ON, SHIFT TO A DIFFERENT GEAR, AND THAN SHIFT PACK TO PARK AND TURN THE CAR OFF. AND REPEAT THIS UNTIL I STOP GETTING THE ALERT. WHEN IT IS PUT IN PARK, THE CAR WILL SHIFT SLIGHTLY IF I GET THIS ERROR. I'VE STARTED USING MY EMERGENCY BREAK WHENEVER I GET OUT OF THE CAR TO MAKE SURE THAT IT WON'T ROLL.

CAR WOULD SHUTTER ON ACCELERATION. RPM GAUGE WOULD JUMP WHEN ACCELERATING OR DOWNSHIFT TO PASS/CLIMB HILL. DEALER FOUND PROBLEM WITH TORQUE CONVERTER. METAL THROUGH OUT TRANSMISSION (SEE ATTACHMENT FOR SPECIFICS AS NOTED BY MECHANIC)

LEFT FRONT HALF SHAFT FRACTURED. WAS MAKING A TURN ON HIGHWAY. VEHICLE HAS 53262 MILES.

I HAVE BEEN HAVING ISSUES WITH THE GMC ACADIA'S SHIFT TO PARK FUNCTION. ON A DAILY BASIS WHILE DRIVING, WHEN I STOP THE CAR AND SHIFT IT INTO PARK, TAKE MY FOOT OFF THE BREAK, AND TURN OFF THE IGNITION, THE CAR BEEPS CONTINUOUSLY AND DISPLAYS A MESSAGE THAT THE CAR IS NOT IN PARK. I TYPICALLY HAVE TO TURN THE CAR ON AND OFF MULTIPLE TIMES OR PUMP MY FOOT ON THE BRAKE MULTIPLE TIMES FOR THE MESSAGE AND SOUND TO CLEAR. THE CAR HAS EVEN CONTINUED TO ROLL FORWARD A FEW TIMES AS WELL WHEN SHIFTED TO PARK AND THE IGNITION OFF.

WHEN I SHIFT TO PARK, WHEN I'M OUT OF MY CAR IT STARTS ROLLING AND SAYING THAT I NEED TO SHIFT TO PARK, EVEN THOUGH I'M ALREADY IN PARK.

WHILE GETTING AN OIL CHANGE AT MY GMC DEALER THEY DISCOVERED THAT A REAR BRAKE PAD WAS SEPARATING FROM THE BACK METAL PLATE IT WAS ATTACHED. THEY SAID IT WAS A SERIOUS SAFETY ISSUE. THEY SAID IT WAS A MANUFACTURING ISSUE AND NOT THE RESULT OF WEAR. THE DEALER SAID THE CAR SHOULD NOT BE DRIVEN. THEY DID NOT HAVE THE REPAIR PARTS SO I TOOK IT TO TUFFY MUFFLER WHO FIXED IT. THEY CONFIRMED IT WAS DUE TO A MANUFACTURING ISSUE.

SHIFT VEHICLE INTO PARK. TURN VEHICLE OFF. WARNING LIGHT COMES ON AND SAYS "SHIFT TO PARK." TURN VEHICLE BACK ON. MOVE SHIFTIER FROM PARK TO 3RD GEAR. TURN VEHICLE OFF. WARNING LIGHT COMES ON AND SAYS "SHIFT TO PARK." DO THIS A FEW MORE TIMES AND IT FINALLY STOPS GIVING ME THE WARNING. IT DOES THIS INTERMITTENTLY.

WHENEVER THE VEHICLE WAS PUT IN PARK AND I ATTEMPTED TO SHUT IT OFF, IT WOULD GIVE ME THE SHIFT TO PARK ERROR CODE AND WOULD NOT LET ME CUT THE CAR OFF COMPLETELY. IT WOULD HAPPEN JUST ABOUT EVERY TIME I DROVE IT. I JUST GOT IT OUT OF THE SHOP FOR THE THIRD TIME AND WAS TOLD THIS TIME THEY REPLACED THE ASSEMBLY. SO FAR IT HAS NOT HAPPENED AGAIN BUT IT HAS ONLY BEEN A WEEK. IT STARTED BACK IN JANUARY 2020.

EVERY TIME I PARK AND TRY TO SHUT CAR OFF THE CAR REFUSES TO TURN OFF AND GIVES A MESSAGE THAT SAYS SHIFT TO PARK. REQUIRES 20+ ATTEMPTS OF RESTARTING, SHIFTING OUT OF PARK AND BACK INTO IT BEFORE SUCCEEDING. CAR IS CLEARLY IN PARK, NOT ROLLING BUT I'M UNABLE TO TURN OFF CAR FULLY. THIS HAS BEEN OCCURRING THE LAST MONTH OR TWO. I BOUGHT THE CAR BRAND NEW.

STOP VEHICLE/ SHIFT TO PARK / TOUCH BUTTON TO TURN OFF VEHICLE/ ENGINE TURNS OFF BUT DRIVER INFORMATION CENTER STATES SHIFT CAR TO PARK. I HAVE TO START THE VEHICLE SHIFT OUT OF PARK THEN BACK TO PARK SHUT OFF ENGINE SEVERAL TIMES BEFORE IT RECOGNIZES IT IS IN PARK.

When I put the vehicle in park and then turn off the engine, a warning comes on the dashboard saying “shift to park” and the electronics will not turn off or the lights and I cannot lock my doors. I cannot leave my vehicle until it goes off. Sometimes it is only a few seconds and can go up to a few minutes. I noticed this problem when I bought the vehicle in 2020 and is a recurring problem and is becoming unbearable that want to trade this vehicle in because I do not want to deal with it.

VEHICLE IS NOT RECOGNIZING THAT IT IS IN PARK THEREFORE RESULTING IN THE VEHICLE NOT SHUTTING OFF

CAR WON'T TURN OFF. THE DASH WARNING SAYS SHIFT TO PARK WHEN THE CAR IS ALREADY IN PARK. YOU HAVE TO SHIFT BACK TO DRIVE SEVERAL TIME FOR THE PARK TO ENGAGE AND THEN SHUT OFF.

WHEN YOU SHIFT INTO PARK, THE CHIMES START GOING OFF AND THE DASHBOARD MESSAGE SAYS 'SHIFT INTO PARK'. I HAVE TO WIGGLE THE SHIFT UNTIL IT SHUTS OFF. SOMETIMES IT TAKES A LOT MORE WIGGLING THAN OTHERS. THIS HAPPENS ABOUT 90% OF THE TIME. THIS HAS HAPPENED SINCE WE PURCHASED IT.

THE TRANSMISDUON SHIFTER WHEN SHIFTED INTO PARK, THE INFORMATION CENTER SAID VEHICLE NOT IN PARK AND IT WILL NOT LET ME SHUT THE CAR OFF IT WAS A 400$ REPAIR AT THE GM DEALERSHIP NOT COVERED UNDER ANY OF MY WARRANTY

VEHICLE DOES NOT RECOGNIZE WHEN IT IS IN PARK. AT TIMES VEHICLE WILL NOT GO INTO PARK AND MAKES ME CONCERNED FOR MY FAMILY'S SAFETY. MY UNDERSTANDING IS THAT GM IS AWARE OF THIS ISSUE.

GEAR SHIFTER MOVES TO PARK POSITION BUT INDICATORS AND ENGINE OFF SWITCH WILL NOT SWITCH TO PARK STATE WITHOUT JIGGLING SHIFTER HANDLE TIP.

THE VEHICLE FAILS TO DETECT WHEN I MOVE THE TRANSMISSION SHIFTER INTO PARK POSITION. I HAVE TO TRY TO TURN OFF THE CAR AND TURN IT BACK ON AND SOMETIMES HAVE TO DRIVE IN IN IT AGAIN AND THEN ATTEMPT TO SHIFT IT TO PARK AND SHUT IT OFF AGAIN. SOMETIMES IT WON'T SHUT OFF, AND THEN I'M STRANDED.

SHIFT TO PARK WHEN I ATTEMPT TO TURN OFF THE VEHICLE. WON'T GO OFF AND CAN'T TURN THE VEHICLE OFF

WHEN I TRY TO TURN OFF MY VEHICLE, MY DASH DISPLAYS THE MESSAGE 'SHIFT TO PARK' EVEN THOUGH I'M ALREADY IN PARK. I HAVE TO JIGGLE THE SHIFTER NOB BACK AND FORTH TO GET IT TO RECOGNIZE IT IS IN PARK. IT'S HAPPENED ABOUT 80% OF THE TIME I TRY TO TURN MY CAR OFF FOR THE LAST COUPLE OF WEEKS.

SHIFT TO PARK . WOULD NOT SHUT DOWN OR COULD NOT LOCK VEHICLE. WARNING LIGHT & BEEPING SOUND. *TR

KEEP GETTING PARKING SHIFT GEAR WARNING EVEN WHEN VEHICLE IS PARKED. HAPPENS FREQUENTLY

SHIFT TO PARK KNOWN ISSUE HAS STARTED. I'VE HAD THE CAR FOR 1 YR. 5 MONTHS. I KNOW THERE ARE LAWSUITS ON THIS ISSUE. CONTINUOUS ISSUE AND GETTING WORSE. THIS NEEDS TO BE TAKEN CARE OF BY GM. IT IS EPIDEMIC IN THEIR ACADIAS. STATIONARY AND PUTTING IT INTO PARK. IT DOESN'T RECOGNIZE IT'S IN PARK! IT'S BEEN OCCURRING OFF AND ON OVER A WEEK, NOT TODAY, EVERY TIME I TRY TO TURN OFF THE VEHICLE.

THE CAR WOULD NOT TURN OFF WHEN PUT IN PARK WHEN THE CAR WAS STOPPED. THE ENGINE WOULD TURN OFF, BUT THE ELECTRICAL DEVICES (LIGHTS, RADIO, ODOMETER READINGS, ETC.) WOULD REMAIN ENGAGED. THE WARNING INDICATOR SAID THE VEHICLE WAS NOT IN PARK AND IT WOULD TAKE 5-10 MINUTES OF TURNING THE ENGINE ON AND OFF, AND SHIFTING BACK AND FORTH IN AND OUT OF GEAR BEFORE THE CAR WOULD TURN OFF COMPLETELY. A SEARCH ON LINE INDICATED SEVERAL PEOPLE COMPLAINING OF THE SAME ISSUE. THIS CAR IS 2 YRS OLD WITH LESS THAN 40K MILES. IT WAS MAINTAINED AS A COMPANY LEASED VEHICLE BY US BEFORE BEING PURCHASED BY US, SO WE KNOW IT HAS BEEN PROPERLY MAINTAINED. WE ENDED UP HAVING TO HAVE THE SHIFT COLUMN REPLACED. *TR

WHEN I SHIFT THE TO PARK AND TRY TO TURN OFF MY CAR THE SHIFT TO PARK LIGHTS UP AND I HAVE TO DOWN SHIFT AND THEN SHIFT TO PARK AGAIN TO GET MY CAR TO SHUT OFF ALSO THE AIR COMPRESSOR HAS ALREADY QUIT WORKING WITH LESS THAN 40K MILES ON IT. *TR

WHEN PARKING CAR IT KEEPS TELLING US TO PARK WHEN IT IS IN PARK AND WE CAN TURN IT OFF

MY VEHICLE WAS STATIONARY. I STOPPED THE VEHICLE AND PLACED THE SHIFT LEVER INTO THE PARK POSITION. WHEN I PRESSED THE START/STOP BUTTON, THE BUTTON'S AMBER WARNING LIGHT CAME ON, AN AUDIBLE WARNING BEGAN SOUNDING AND ALL INSTRUMENT LIGHTS STAYED ON. WHEN I LOOKED AT THE DRIVER'S DISPLAY, IT STATED, "SHIFT TO PARK". (THE SHIFT LEVER WAS ALREADY IN THE PARK POSITION. I COULD NOT SHUT THE VEHICLE DOWN AND COULD NOT LEAVE THE VEHICLE IN THAT CONDITION. I CONTINUED TO MOVE THE SHIFT LEVER FROM DRIVE TO PARK AND AFTER 8-10 SHIFTS, THE VEHICLE FINALLY RECOGNIZED THAT IT WAS IN PARK. THEN, THE START/STOP BUTTON FUNCTIONED CORRECTLY. UPON INVESTIGATION, I FOUND THAT THIS IS A VERY COMMON PROBLEM WITH 2017-2018 GMC ACADIAS (THERE IS EVEN A CLASS ACTION LAW SUIT PENDING). SOME OWNERS EVEN REPORT THEIR VEHICLES ROLLING WHEN IN THIS CONDITION. AS OF THIS DATE (5/19/2020) GM HAS NOT RECOGNIZED THIS AS A DESIGN PROBLEM AND HAS NOT ISSUED A RECALL. THIS IS OBVIOUSLY A DESIGN ISSUE SINCE IT HAPPENS WITHIN AND OUT OF THE 3YR/36,000 MILE WARRANTY. IF IT HAPPENS AT 36,500 MILES THE VEHICLE OWNER IS OUT OF LUCK! THIS IS ALSO, OBVIOUSLY, A SAFETY ISSUE. THANKS FOR YOUR TIME AND HELP. *TR

WHEN YOU SHIFT TO PARK THE VEHICLE DOES NOT GO INTO PARK. TOOK IT TO THE DEALERSHIP AND THEY REPLACED THE JUMPER HARNESS (84733196) ON MAY 1, 2020. THAT DID NOT FIX THE ISSUE ON JULY 24, 2020 DEALERSHIP REPLACED THE SHIFTER (84699764) TRANS CONTROL. THIS OCCURS WHEN WE ARE STATIONARY ATTEMPTING TO PLACE THE VEHICLE INTO PARK FROM DRIVER OR REVERSE.

I HAVE RECEIVED THE 'SHIFT TO PARK' ERROR MESSAGE ON THE DASH WHEN THE CAR IS ALREADY IN PARK. ONE TIME WITH THE CAR OFF, THE ERROR MESSAGE ON, THE CAR STARTED TO ROLL DESPITE IT BEING IN PARK. I HAD TO RESTART THE CAR, SHIFT THE SHIFTER DOWN THEN BACK TO PARK BACK DOWN AND BACK TO PARK BEFORE THE CAR WOULD RECOGNIZE THE SHIFTER WAS IN PARK. EACH TIME THIS HAPPENED WHEN I WAS IN A PARKING SPOT AND IN MY GARAGE.

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.

THE SECOND ROW SEATS GET STUCK FROM TIME TO TIME WHEN ATTEMPTING TO FOLD THEM DOWN. WE HAVE ALSO BEEN HAVING ISSUES WITH THE SHIFT GEAR WHEN TRYING TO PLACE IT IN PARK. WHEN THE CAR IS PLACED IN PARK AND WE TRY TO TURN IT OFF, THE CAR WILL REFUSE TO SHUT OFF AND WILL DING UNTIL FINALLY THE CAR REGISTERS THAT THE SHIFT GEAR IS IN PARK. I HAVE TO TURN ON AND OFF THE CAR MULTIPLE TIMES, AND EVEN WIGGLE THE GEAR MULTIPLE TIMES BEFORE THE SYSTEM FINALLY RECOGNIZES THAT THE CAR IS IN PARK.

WHEN I SHIFT THE CAR TO PARK AFTER DRIVING I RECEIVE A "SHIFT TO PARK" MESSAGE. THE VEHICLE IS IN PARK BUT WILL NOT REGISTER.

SHIFTER ASSEMBLY WENT OUT, KNOWN ISSUE AND GM WON'T COVER PART

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT AFTER STOPPING THE VEHICLE AND PLACING THE GEAR SHIFTER IN PARK, A MESSAGE DISPLAYED TO SHIFT THE VEHICLE INTO PARK. THE CONTACT SHIFTED THROUGH THE GEARS AND THE VEHICLE OPERATED AS INTENDED. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE MANUFACTURER NOR THE DEALER WERE NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 41,000. THE VIN WAS INVALID.

Shift to park msg appears randomly causing the car to not completely turn off even though car is in park. Have to turn car back on and shift to drive back to park couple of times before msg goes away. I see so many people with the same problem why isn't there a recall this is a safety issue. The 1st time my warranty covered the repairs , 2nd time around I have to pay of pocket.

I own a 2018 GMC Acadia and sometimes after shifting the vehicle into park and turning it off I get a message that says "shift into park" even though it is in park. This happens intermittently and but it is a bit of a pain when it does. I have to either jiggle the shifter or start the car up again and shift into park again. I just called the GMC dealer where I purchase the vehicle new, Mark Porter in Pomeroy, OH, and they said there is a bulletin from GMC on it and the fix is to replace the shifter harness which would cost me around $300. And they said if that doesn't fix the problem the next step would be to replace the shifter which would cost me another $500. In looking online it seems to be happening to a lot of 2018 GMC Acadia's and am wondering why there is no recall on it.

WENT CAR IS PARK THE DASH STILL SHOWS 'PUT CAR IN PARK' CAR WILL CONTINUE TO PEE, WILL NOT LOCK. FROM WHAT I READ GMC KNEW OF THIS PROBLEM BUT CONTINUE TO SELL GMC ARCADIA FROM 2017 TO 2018. EVEN THOUGH THIS IS A KNOWN PROBLEM THEY STILL CHARGE THE CONSUMERS FOR THE REPAIRS. THIS ONLY HAPPENED WENT TRYING TO PUT VEHICLE I PARK.

WHEN I PUT MY VEHICLE IN PARK, IT WILL NOT SHUT OFF AND DASHBOARD IT SAYS 'ACTION REQUIRED. SHIFT TO PARK.' VEHICLE WON'T TURN OFF AND IT KEEPS BEEPING. IT IS WHEN I'M PARKED

SHIFT TO PARK. SENSOR WON'T SHUT OFF. *TR
