VEHICLE STATES, 'SHIFT TO PARK,' WHEN TRYING TO TURN OFF ENGINE WHEN IT IS ALREADY IN PARK. TURN VEHICLE BACK ON AND HAVE TO SHIFT MULTIPLE TIMES OUT AND THEN BACK INTO PARK BEFORE CAR WILL RECOGNIZE IT IS IN FACT IN PARK TO SHUT DOWN ENTIRE ENGINE. HAVE REPLACED BATTERY ONCE ALREADY. VEHICLE IS STATIONARY AND FOOT IS ON BREAK WHEN TRYING TO TURN CAR OFF. HAS BEEN HAPPENING SINCE PURCHASE BUT, JUST GOT FED UP WITH IT.

WHEN CAR IS PLACED IN PARK, THE DASHBOARD DISPLAY SAYS THAT THE CAR MUST BE SHIFTED TO PARK, ALTHOUGH IT IS HAS BEEN PUT IN PARK. THE CAR MUST BE RESTARTED, AND RESHIFTED TO PARK, MULTIPLE TIMES. (AS MANY AS A DOZEN TIMES.) WHEN THE ERROR MESSAGE APPEARS THE ELECTRICAL COMPONENTS DO NOT SHUT DOWN. THE CAR CANNOT BE LOCKED. UNSURE WHETHER CAR IS/ IS NOT ACTUALLY IN PARK, OR WHETHER THERE IS A DANGER OF CAR ROLLING AWAY.

AT TIMES WHEN SHIFTING CAR FROM DRIVE TO PARK THE CAR WILL NOT SEAT INTO PARK AND PROVIDES A MESSAGE SHIFT TO PARK. CAR IS IN A STATIONARY POSITION BUT AT TIMES WILL NOT ALLOW ME TO TURN OFF POWER TO CAR BECAUSE OF THE SHIFT TO PARK ISSUE.

I AM GETTING A MESSAGE SHIFT TO PARK! ON 2017 GMC ACADIA AFTER PUTTING MY VEHICLE IN PARK UNABLE TO LOCK CAR AND LIGHTS AND RADIO REMAIN ON. IT TOOK ME MORE THAN AN HOUR TO GET MY VEHICLE TO STOP DISPLAYING MESSAGE. I AM VERY CONCERNED AND APPALLED AT THE SAME TIME UPON INVESTIGATING I HAVE DISCOVERED GMC IS AWARE OF THIS PROBLEM AND DOES NOT HAVE A FIX FOR IT. I REALLY WISHED IT WOULD HAVE BEEN REVEALED AND I COULD HAVE CHOSEN ANOTHER VEHICLE THAT IS VERY BAD BUSINESS PRACTICES MY VEHICLE IS ONLY TWO YEARS OLD AND I AM STILL MAKING PAYMENTS.

AFTER 2 YEARS OF OWNERSHIP OF A NEW GMC ACADIA MY SUV WOULD NOT SHUT OFF ONCE I PARKED MY CAR. IT WOULD NOT BE ABLE TO DETECT THAT I SHIFTED INTO PARK AFTER ARRIVING AT MY DESTINATION. ALL THE ELECTRONICS WOULD CONTINUE TO RUN. I WOULD HAVE HAVE TO STAY IN THE CAR AND PLAY WITH THE SHIFTER UNTIL THE COMPUTER FINALLY READ THAT IT WAS IN PARK. AFTER TAKING THE CAR TO THE DEALERSHIP THE SUV WAS FIXED WITH AN NEW PART THAT SEEMS TO HAVE RESOLVED THE PROBLEM FOR NOW BUT AS FAR AS I AM AWARE GMC IS STILL DOESN'T KNOW WHY THE PROBLEM IS BEING CAUSED SO I AM WAITING TO SEE IF IT HAPPENS AGAIN. AFTER GETTING IT FIXED NOW MY VEHICLE GIVES ME ANOTHER WARNING EVERY TIME MY "AUTO ENGINE OFF" IS ACTIVATED AT WHEN I COME TO A STOP. NOW I CONTINUOUSLY GET "STEBILITITRC" WARNING EVERY TIME I STOP. THEY FIXED ONE PROBLEM AND NOW I HAVE ANOTHER. IT IS MY FAMILY CAR SO I JUST WANT TO MAKE SURE IT IS SAFE BUT GMC DOESN'T SEEM TO KNOW WHATS WRONG OR HOW TO FIX IT EVEN THOUGH THEY ARE AWARE OF MANY ACADIAS HAVING THE SAME PROBLEM.

"SHIFT TO PARK" ISSUE AS DESCRIBED BY OTHERS. GM DEALER SAYS IT NEEDS TO REPLACE A $20.00 HARNESS + LABOR OF OVER $200.00. "SERVICE PARKING BRAKE" ISSUE THAT RANDOMLY PRESENTED ITSELF ONE DAY. I WAS UNABLE TO USE THE PARKING BRAKE. GM DEALER HAD TO "UPGRADE" MY EBCM FOR A WHOPPING $200.00. HOW DOES GM THINK THE CONSUMER SHOULD HAVE TO PAY FOR THIS. THEY HAVE A MONOPOLY BECAUSE THEY ARE THE ONLY ONES THAT CAN FIX THIS!

WHEN PUTTING THE VEHICLE INTO PARK, AN ERROR IS DISPLAYED STATING TO SHIFT THE VEHICLE INTO PARK, EVEN THOUGH THE SHIFTER IS IN P. IN ORDER TO GET THIS MESSAGE TO GO AWAY, I HAVE TO MOVE THE SHIFTER UP AND DOWN MULTIPLE TIMES. COULD TAKE UP TO 20 MIN TO GET THE ERROR TO GO AWAY. I CAN NOT LEAVE THE VEHICLE UNTIL THE ERROR IS OFF BECAUSE THE LIGHTS STAY ON AND WILL DRAIN THE BATTERY. I ALSO NOTICE THAT THE VEHICLE ROLLS A LITTLE MORE AFTER MULTIPLE ATTEMPTS TO GET ERROR MESSAGE OFF. THIS IS CONCERNING THAT IT MAY NOT REALIZE ITS IN PARK AND ROLL INTO ANOTHER VEHICLE CAUSING DAMAGE TO BOTH OR ROLL AWAY. I TOOK TO MY DEALER AND WAS TOLD THIS IS A 'KNOWN' ISSUE AND IS NOT COVERED UNDER WARRANTY, NOR IS THERE A RECALL. I JUST PAID OUT OF POCKET FOR NEW TIRES BECAUSE GM KNEW THE TIRES PLACED WERE 'WEARING' TOO SOON BASED ON MILEAGE. NOW, I AM BEING TOLD I WILL HAVE TO PAY ABOUT $600 TO GET THIS FIXED. GM KNOWS OF ISSUES AND NOT FIXING THEM IS WRONG. THIS IS NOT A NEW ISSUE, HAS BEEN LISTED AS COMPLAINTS FOR THE PAST YEAR, YET GM HAS DONE NOTHING TO FIX AND CONTINUE TO MAKE THE VEHICLE WITH THE SAME ISSUES. FRUSTRATING THAT I HAVE TO SPEND THE MONEY TO FIX AN ISSUE THEY KNOW ABOUT! THIS NEEDS PUSHED BACK TO GM TO HOLD THEM ACCOUNTABLE AND MAKE THIS RIGHT. THE SHIFTER ISSUE SHOULD BE A RECALL AND FIXED.

VEHICLE SAYS SHIFT TO PARK AND WON'T TURN OFF, EVEN THOUGH IT IS ALREADY IN PARK.

2017 ACADIA IS DISPLAYING 'SHIFT TO PARK' MESSAGE WHEN THE CAR IS IN PARK. I HAVE TO TURN THE CAR OFF AND ON AND SHIFT TO OTHER GEARS AND BACK TO PARK UPWARDS OF 5/10 TIMES PRETTY MUCH EVERY TIME I TRY TO TURN THE CAR OFF.

NHTSA ODI 11255608

WHEN SHIFTING THE VEHICLE TO PARK AND THEN SHUTTING OFF THE ENGINE, I GET AN ERROR MESSAGE 'ACTION REQUIRED- SHIFT TO PARK'. THE VEHICLE IS ALREADY IN PARK! I'VE HAD TO JIGGLE THE SHIFTER, PRESS THE BRAKE WHILE JIGGLING THE SHIFTER, RESTART THE VEHICLE PUT IN REVERSE, THEN BACK IN PARK, AND JIGGLE SOME MORE. THE RADIO AND LIGHTS (BOTH INTERIOR & EXTERIOR) WILL NOT POWER OFF AND THE DOOR CHIMES NONSTOP. THIS HAPPENS RANDOMLY AND IT HAS BEEN A LITTLE OVER A MONTH SINCE THE LAST INCIDENT WHICH OCCURRED TWO DAYS AFTER I HAD TO REPLACE THE BATTERY BECAUSE I MISSED THE ERROR MESSAGE HEADING IN TO WORK. THE LAST 2 DAYS MY HUSBAND HAS DISCONNECTED THE BATTERY BECAUSE NOTHING WILL WORK TO POWER OFF RADIO & LIGHTS. I'VE HAD TO REPLACE THE BATTERY TWICE NOW IN A NEW VEHICLE LEASED IN 2016. THE FIRST TIME WAS DUE TO BRAKE RECALL, MY VEHICLE BEING THE ONLY 2017 GMC ACADIA DENALI EFFECTED BY THAT RECALL. THE BRAKE LIGHTS WOULD REMAIN ON BECAUSE THE BRAKE WAS BASICALLY STICKING, DRAINING THE BATTERY. THAT ISSUE ALSO DISABLED THE CRUISE CONTROL AS THAT FEATURE IS UNAVAILABLE WHEN BREAKING! THIS VEHICLE ALSO HAD REPAIR TO WIRING IN DRIVER SIDE DOOR DUE TO WATER GETTING INTO THE DOOR FRAME FROM OUTSIDE AND CORRODING WIRES CAUSING DETECTION ISSUES WITH THE KEY FOB. I COULD NOT UNLOCK MY DOORS WITHOUT REMOVING THE KEY TO MANUALLY UNLOCK. WHILE IN THE CAR WASH, THE VEHICLE LOST CONNECTION WITH MY KEY AND THE DRIVER'S SEAT MOVED ALL THE WAY BACK AS IT WOULD FOR EASY EXIT WHICH I HAD DISABLED. MESSAGE STATING KEY NOT DETECTED WOULDI WAS TOLD A NEEDED A NEW BATTERY IN MY FOB, DEALERSHIP REPLACED, CALLED & SAID EVERYTHING WAS WORKING AS IT SHOULD. THEY RAN THE VEHICLE THROUGH THE CAR WASH BEFORE I ARRIVED TO PICK UP THE CAR. WHEN I TRIED TO UNLOCK THE DOORS, THE VEHICLE WOULD NOT RECOGNIZE THE FOB. THANK GOODNESS THE SERVICE REP WAS THERE TO WITNESS THE MALFUNCTION.

UPON TURNING MY IGNITION OFF, THE "SHIFT TO PARK" WARNING MESSAGE APPEARS, EVEN THOUGH THE DISPLAY SHOWS THAT I AM IN "P" AND THE BRAKE IS ON. WHEN I TOOK IT TO THE DEALERSHIP,I GOT OUT OF THE CAR AND POINTED TO THE MESSAGE ON MY DISPLAY. BEFORE THE TECHNICIAN EVEN LOOKED INTO MY CAR, HE ASKED "SHIFT TO PARK"? SO OBVIOUSLY THIS IS A WELL KNOWN PROBLEM WITH THIS GMC REPAIR CENTER. MY FRUSTRATION IS THAT IF IT IS A KNOWN DEFECT, WHY DO I HAVE TO PAY TO HAVE IT FIXED?

NHTSA ODI 11255355

UPON SHIFTING THE CAR TO PARK AND SHUTTING OFF THE ENGINE, THE CONSOLE SAYS, "SHIFT TO PARK". THE CAR APPEARS TO ROLL SOME. I HAVE NOT BEEN ON AN INCLINE TO SEE IF IT IS TRULY IN PARK OR NOT. IT WILL NOT ALLOW THE ELECTRONICS TO SHUT OFF AND WILL NOT LET YOU LOCK THE CAR SO THE CAR CANNOT BE LEFT WHEN THIS HAPPENS. IT HAS BEEN HAPPENING INTERMITTENTLY AND TODAY I HAD TO SHUT OFF AND START THE CAR AND DRIVE IT 10-15 TIMES BEFORE IT WOULD RECOGNIZE IT WAS ACTUALLY IN PARK.

"SHIFT TO PARK" ERROR WHEN CAR IS ALREADY IN PARK. ISSUE STARTED ABOUT 2 MONTHS AGO; HOWEVER, IT IS BECOMING WORSE AND MORE FREQUENT. MOST OF THE TIME, PRESSING THE SHIFTER BUTTON IN/OUT WILL TURN THE CAR OFF BUT NOT IT CAN TAKE UP TO 5 MINUTES OF TURNING THE CAR ON/OFF AND SHIFTING GEARS TO GET THE CAR TO RECOGNIZE THAT IT IS IN PARK. (THE DASHBOARD DOES RECOGNIZE THAT IT IS IN PARK WITH THE "P" BESIDE THE MILEAGE BUT THE SENSOR DOES NOT.) IT IS A SAFETY CONCERN BECAUSE THE CAR CAN NOT BE TURNED OFF AND LOCKED. DESPITE ONLY HAVING THE CAR FOR A LITTLE OVER 2 YEARS, THE DEALERSHIP SAYS THE COSTS NEEDS TO BE COVERED OUT OF POCKET SINCE IT WAS A LOANER.

UPON TURNING VEHICLE OFF, "SHIFT TO PARK!" ILLUMINATES ON THE CLUSTER. VEHICLE WILL NOT TURN OFF UNTIL IT IS RE-STARTED, SHIFTED IN AND OUT OF GEAR. SOMETIMES THIS NEEDS TO BE DONE MULTIPLE TIMES. THERE HAS BEEN ONE INSTANCE THE ERROR WOULD NOT CLEAR, AND I WAS FORCED TO LEAVE MY VEHICLE ON, AS I WENT INTO A DOCTOR APPOINTMENT. THIS IS VERY ANNOYING, NOT TO MENTION THE WASTED FUEL WITH STARTING/STOPPING THE VEHICLE 5-10 TIMES EACH TIME I TURN IT OFF. I'VE TAKEN VIDEO OF THE PROBLEM, HOWEVER, IT IS TOO LARGE TO UPLOAD HERE. RIDICULOUS.

SHIFTER KEEPS LOCKING. HAPPENED 4 TIMES WHERE SHIFTER HAD GOTTEN STUCK IN SHIFT AND UNABLE TO CONTROL CAR. GEAR ASSEMBLY HAS BEEN REPLACED 4 TIMES AND NOTHING IS WORKING.

NHTSA ODI 11254857

I REPORTED A PROBLEM OVER A YEAR AGO, AND DESPITE SEVERAL TRIPS TO THE DEALER, THE PROBLEM HAS GOTTEN WORSE. THE VEHICLE SEEMS TO SHIFT TO NEUTRAL WHILE SHIFTING FROM 2ND TO 3RD GEARS. THIS RESULTS IN A VERY HARSH SHIFT. THE MAIN SAFETY ISSUE IS THAT WHILE YOU ARE TRYING TO ACCELERATE, YOUR VEHICLE GOES INTO NEUTRAL AND YOU NEARLY STOP. NOT ONLY HAVE I BEEN SLAMMED INTO MY SEAT WHEN IT FINALLY CATCHES IN THE NEXT GEAR, BUT I'VE ALMOST BEEN REAR ENDED MULTIPLE TIMES. IT IS VERY DANGEROUS. THE DEALER CLAIMS IT'S "DOING WHAT ITS SUPPOSE TO".

TL* THE CONTACT OWNS A 2017 GMC ACADIA. THE CONTACT STATED THAT THE VEHICLE WOULD NOT SHUT OFF AND THE ENGINE RAN FOR HOURS. EVENTUALLY, THE INTERNAL SYSTEM RECOGNIZED THAT THE VEHICLE WAS IN PARK AND FINALLY TURNED ITSELF OFF. THE MANUFACTURER HAD NOT DONE ANYTHING TO ADDRESS THE FAILURE; HOWEVER, THEY ISSUED TECHNICAL SERVICE BULLETIN NUMBER: 18-NA-297 ON DECEMBER 13, 2018. THE CONTACT CALLED NUMEROUS UNKNOWN DEALERS ACROSS THE COUNTRY TO TRY TO BUY THE PART MENTIONED IN THE SERVICE BULLETIN, BUT THE PART WAS STILL ON BACKORDER. THE PART THAT WAS NEEDED FOR THE REPAIR WAS THE TRANSMISSION SHIFTER ASSEMBLY (NUMBER: 13528228). THE COST OF THE PART WAS LESS THAN $150. THE CONTACT STATED THAT THE VEHICLE WAS OUT OF ITS INITIAL WARRANTY. THE FAILURE MILEAGE WAS 47,500. THE VIN WAS UNKNOWN. *TR

THE CAR WILL NOT RECOGNIZE OR SHIFT TO PARK.. THE CAR WILL NOT TURN OFF WHILE THE SHIFTER IS IN PARK THINKING THAT THE CAR ISN'T IN PARK. THIS IS A SAFETY ISSUE SINCE YOU BELIEVE IT IS IN PARK WHEN THE CAR IS SAYING IT ISN'T AND WILL NOT CLEAR THE ALERT UNLESS YOU CONTINUOUSLY TURN THE VEHICLE ON AND OFF AND TOGGLE THE SHIFTER. I HAVE A VIDEO OF THE ISSUE BEING REPORTED

OUR 2017 GMC ACADIA DENALI SAYS TO PUT THE CAR IN PARK BEFORE TURNING IT OFF WHEN THE CAR IS ALREADY IN PARK AND ENGINE OFF. ALL ELECTRONICS STAY ON AND WILL KILL THE BATTERY.

NHTSA ODI 11254189

WHEN PARKING THE VEHICLE AND ATTEMPTING TO SHUT OFF, THE ACADIA GIVES THE MESSAGE "SHIFT TO PARK". THE VEHICLE IS CLEARLY IN PARK AND I MUST START THE VEHICLE AGAIN AND SHIFT TO REVERSE OR ANOTHER POSITION AND TURN OFF. THE VEHICLE WILL NOT ALLOW ME TO LOCK THE VEHICLE AND KEEPS POWER TO THE VEHICLE (DRAINING THE BATTERY) UNTIL IT RECOGNIZES THAT IT IS INDEED IN PARK. THIS HAS CAUSED A STALL AND THE VEHICLE TO POSSIBLY STILL BE IN GEAR WHEN PARKED LEADING TO A ROLLING HAZARD. HAS TAKEN AS MANY AS 15 TIMES FOR THE VEHICLE TO REALIZE IT IS IN PARK. GENERAL MOTORS HAS ISSUED A TSB (18-NA-297) REGARDING THIS ISSUE, BUT IS PLACING THE COST OF THE FIX ON THE CONSUMER. THIS IS A DEFECTIVE PIECE OF EQUIPMENT THAT HAS STARTED A CLASS ACTION LAWSUIT.

NHTSA ODI 11253759

WHEN YOU SHIFT INTO PARK, THE VEHICLE DOES NOT REGISTER AS BEING IN PARK. THERE IS AN INDICATOR ON THE GAUGE PANEL SAYING "SHIFT TO PARK." THIS IS A SAFETY ISSUE, THE ENGINE CANNOT BE TURNED OFF WHILE IN THIS CONDITION AND IT DOES NOT REGISTER THE TRANSMISSION AS BEING IN PARK. THIS HAPPENS EVERY TIME THE VEHICLE IS SHIFTED INTO PARK ONCE THE VEHICLE IS STOPPED.

NHTSA ODI 11253406

SHIFT TO PARK RECALL - THIS IS A SAFETY ISSUE. MY ACADIA WAS IN PARK AND I TURNED THE CAR OFF AND I GOT AN ERROR CODE THAT SAID ACTION REQUIRED SHIFT TO PARK. I HAD TO TURN THE CAR BACK ON PUT IT IN DRIVE AND BACK INTO PARK AND TURN THE CAR OFF THE STOP THE BEEPING. I SPOKE TO FLEMINGTON GMC AND THIS ISSUE IS NOT A RECALL. THIS MAKES NO SENSE TO ME THE ERROR CODE READS ACTION REQUIRED SHIFT TO PARK. WHICH CLEARLY MEANS THE CAR IS NOT IN PARK IF IT'S TELLING YOU TO SHIFT TO PARK WHEN YOU ALREADY PUT IT IN PARK AND TURNED THE CAR OFF USING THE START STOP BUTTON. I AM STILL WAITING FOR A PHONE CALL FROM AMBER AT GMC AS I WAS SUPPOSE TO BE CALLED ON 9/3/19 REGARDING THIS ISSUE.
