2018 GMC Acadia complaints

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.

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

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.

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.

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.

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT WHILE THE VEHICLE WAS IN A STAND STILL AND TURNING OFF THE VEHICLE, THE VEHICLE WOULD START TO BING, LIGHTS WOULD STAY ON, AND DOORS WOULD NOT LOCK. THE SHIFT TO PARK MESSAGE DISPLAYED ON THE INSTRUMENT PANEL. THE VEHICLE WAS TAKEN TO GET REPAIRED WHERE THE MANUAL TRANSMISSION MODE SWITCH WAS REPLACED, HOWEVER THE FAILURE PERSISTED. THE VEHICLE WAS TAKEN TO A LOCAL DEALER (CHESROWN CHEVROLET BUICK GMC LOCATED AT 1701 COLUMBUS PIKE, DELAWARE, OH 43015) WHERE IT WAS DIAGNOSED THAT THE SHIFTIER ASSEMBLY NEEDED TO BE REPLACED. THE VEHICLE HAD NOT BEEN REPAIRED AS OF YET. THE MANUFACTURER HAD BEEN INFORMED OF FAILURE, HOWEVER NO ASSISTANCE WAS OFFER. THE FAILURE MILEAGE WAS APPROXIMATELY 38,000. *DT THE CONSUMER STATED THE VEHICLE DISPLAY "SHIFT INTO PARK" ERROR. WHEN PLACING IT IN PARK. THE VEHICLE'S HEADLIGHTS AND INTERIOR LIGHTS REMAINED ILLUMINATED, AS WELL AS THE RADIO. ALSO, THE DOORS WOULD NOT LOCK. THE CONSUMER STATED THE SECTION OF THE SHIFTER THAT BOLTS INTO THE FLOOR NEEDED TO BE REPLACED. *THE VEHICLE WAS REPAIRED. JS

WHEN TRYING TO PUT IN PARK WON'T SHUT OFF SAYS SHIFT TO PARK, STARTED AROUND 25,000 MILES HAVE TO BE SURE VEHICLE IS LEVEL AND NOT ON AN INCLINE. VEHICLE ALSO SURGES AT TIMES LOOSING POWER WHEN YOU'RE GOING DOWN THE HIGHWAY. ALSO, AT TIMES WHEN YOU GO TO START VEHICLE IT WILL HESITATE AND DISCONNECTS FROM BATTERY THUS RESETTING EVERYTHING. HAD TO REPLACE BATTERY AT 25,000 . THE REAR WIPER WILL GO ON IT'S ON WITHOUT TURNING IT ON.

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

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

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

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.

"SHIFT TO PARK" ISSUE. WHEN OUR 2018 GMC ACADIA IS PLACED IN PARK, THE DIC DISPLAYS THAT THE VEHICLE IS NOT IN PARK WHEN IT IS INDEED IN PARK. NEVER SURE IF TRANSMISSION IS TRULY IN THE PARK POSITION AND CANNOT ROLL, BUT THERE IS NO CONFIRMATION OF THIS. THIS INDICATION FAILURE PREVENTS US FROM LEAVING THE VEHICLE FOR A SUBSTANTIAL AMOUNT OF TIME UNTIL WE (IF EVER) SEE THE PROPER "PARK" INDICATION.

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.

2018 GMC ACADIA SHOWN 'SHIFT TO PARK' MESSAGE EVEN CAR IS STOPPED/ PARKED.

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.

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.

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.

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.

DRIVES SIDE SEATBELT BASE RELEASE LATCH. SEATBELT WILL NO LONGER LATCH. SEAT BELT WAS NOT PULLED, OCCURRED WHILE CAR WAS IN PARK.

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.

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

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.

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

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

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.

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 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

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 TRY TO PUT THE CAR IN PARK IT STATES THAT ITS NOT IN PARK. IT WILL NOT SHUT OFF. YOU HAVE TO START THE CAR AND SHUT OFF MULTIPLE TIMES AND HOPE THAT WORKS. I'VE LOOKED IT UP AND THERE IS A LAWSUIT ABOUT IT BUT NO RECALL. IT DOES THIS EVERY TIME I DRIVE SOMEWHERE AND TRY TO TURN MY CAR OFF. *TR

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.

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. SENSOR WON'T SHUT OFF. *TR

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.

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.

WHEN ATTEMPTING TO TURN THE VEHICLE OFF AFTER SHIFTING TO PARK AND THEN PRESSING THE START/STOP BUTTON, THE VEHICLE GIVES AN ERROR MESSAGE THAT SAYS "SHIFT TO PARK" EVEN THOUGH THE SHIFT LEVER IS IN THE PARK POSITION. THE ERROR MESSAGE PREVENTS THE VEHICLE FROM SHUTTING DOWN. THIS OCCURS WHEN THE VEHICLE IS STOPPED, PUT INTO PARK, AND THEN WHEN ATTEMPTING TO SHUT DOWN THE VEHICLE.

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

TL* THE CONTACT OWNS A 2018 GMC ACADIA. THE CONTACT STATED THAT WHEN THE GEAR WAS SHIFTED INTO PARK, A WARNING BEEP SOUNDED, INFORMED THE DRIVER THAT THE VEHICLE WAS NOT IN PARK. THE CONTACT WAS UNABLE TO TURN THE VEHICLE OFF. AFTER SEVERAL ATTEMPTS, THE CONTACT WAS ABLE TO SHIFT THE VEHICLE INTO PARK AND TURN THE VEHICLE OFF. THE MANUFACTURER WAS CONTACTED. THE VEHICLE WAS NOT TAKEN TO THE DEALER TO BE DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 37,000. THE VIN WAS INVALID.

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

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.

VEHICLE WILL NOT ACKNOWLEDGE THAT IT IS IN PARK. FORCES ELECTRICAL TO STAY ON, AND SOMETIMES WILL NOT ENGAGE PARK SO VEHICLE CAN MOVE AS IF I'M NEUTRAL. HAS THUS FAR HAPPENED WITH VEHICLE STOPPED, BUT YOU CAN SOMETIMES SHUT OFF ENGINE AND EXIT VEHICLE WHEN IT IS NOT IN PARK AND CAN ROLL AGAINST YOU, OR ON KIDS EXITING ETC. VEHICLE ROLLED IN GARAGE AND STRUCK, AND COULD HAVE CRUSHED CHILD AGAINST DOOR.

AFTER PUTTING THE VEHICLE IN PARK, "SHIFT TO PARK" IS DISPLAYED ON THE DASH. I HAVE TO SHIFT THE CAR IN AND OUT OF PARK SEVERAL TIMES TO GET THE VEHICLE TO RECOGNIZE BEING IN PARK.

WHEN THE VEHICLE IS WARM, THE TRANSMISSION APPEARS TO SLIP WHEN SHIFTING FROM 2ND TO 3RD GEAR. THE ENGINE WILL REV BETWEEN 500 TO 1000 RPM WHILE SHIFTING. DURING THIS TIME (HALF TO FULL SECOND) THE VEHICLE IS NOT ACCELERATING AND DOES NOT RESPOND TO THROTTLE INPUTS. THE VEHICLE HAS BEEN TAKEN INTO DEALERSHIPS 4 TIMES FOR THIS COMPLAINT. AT 35000 MILES (3RD DEALER VISIT), GM REPLACED THE VALVE ASSEMBLY. THE PROBLEM REOCCURRED AND GM IS ONLY OFFERING TO REPLACE THE SAME PART, OR EXTEND THE WARRANTY ON THE TRANSMISSION, BUT NOT BOTH. NO ONE AT THE DEALERSHIP OR GM TECHNICAL ASSISTANCE CENTER HAS ANY IDEA WHAT IS ACTUALLY WRONG AND IS NOT TAKING ANY STEPS TO FIND THE CAUSE OF THE ISSUE. THE SERVICE MANAGER HAS ADMITTED THAT THERE IS A PROBLEM, BUT GM DENIED HIM ANY HELP IN RESOLVING THE ISSUE.THEY HAVE SAID THAT THIS IS NOT A SAFETY ISSUE, BUT I DO NOT FEEL COMFORTABLE DRIVING A CAR THAT MAY BECOME UNRESPONSIVE TO ACCELERATOR PEDAL INPUT FOR A FULL SECOND. NOTE THAT THIS ISSUE IS STILL COVERED BY THE POWERTRAIN WARRANTY AT THIS TIME.

"SHIFT TO PARK" MESSAGE READS ON DASH, WHEN THE CAR IS IN PARK AND THEN IT WONT LET YOU TURN THE CAR OFF. I HAVE SPEND OVER 20 MINUTES TRYING TO GET IT TO "READ" THAT THE CAR IS IN PARK. I EVEN TOOK IT INTO GMC TO "FIX" THE PROBLEM. THEY "FIXED" IT BUT NOW IT IS HAPPENING AGAIN.

PARK THE CAR SHUT OFF ENGINE AND A MESSAGE COMES UP PLEASE SHIFT TO PARK. THE CAR IS IN PARK BUT IT'S NOT BEING RECOGNIZED BY THE COMPUTER OR DRIVETRAIN? HAVE TO PLAY WITH THE SHIFTER TO BE ABLE TO SHUT OFF CAR . ONLY HAPPENS WHEN PARKED AND SHUTTING OFF CAR.

PUT CAR IN PARK WENT TO KILL IT AND IT WONT TURN OFF SAYS SHIFT TO PARK IT IS IN PARK HAD TO DO THIS LIKE 10 TIMES ..TWICE TODAY..MY CAR WONT TURN OFF FINALLY GOT IT OFF. I HAVE ONLY HAD THIS 2018 ACADIA LEAD THAN 1 MTH.. I HAVE READ WHERE THIS IS A BIG MAJOR ISSUE.. WHAT DO I DO

WHEN THE VEHICLE IS SHIFTED INTO PARK AND THE IGNITION IS TURNED OFF, AN ERROR MESSAGE IS SHOWN SAYING "SHIFT VEHICLE INTO PARK". USUALLY PUSHING THE SHIFT KNOB FORWARD AND RELEASING IT WILL MAKE THE ERROR MESSAGE DISAPPEAR BUT THERE HAVE BEEN TIMES THAT THE VEHICLE HAD TO BE TURNED ON AND OFF MULTIPLE TIMES AS WELL AS SHIFTING FROM DRIVE TO PARK MULTIPLE TIMES TO MAKE IT GO AWAY AND TURN THE VEHICLE OFF.
