2017 GMC Acadia UNKNOWN OR OTHER

When shifting into park, getting a Shift to Park error. Have to jiggle the shifter to get the car to turn off. Sometimes it won’t turn off. About a month after purchasing used in 2020 my wife put the car into park in our drive way, the car rolled backwards with my son in it and the passenger side door open. The passenger side door hit a tree and folded the door backward toward the body. Door had to be replaced. Luckily no one was injured. At the time we did not know about the shifter issue. Secondly our transmission has now gone out with only 80k miles on the car. This is another reoccurring issue that GMC has ignored with a know manufacturer default in the transmission.

Vehicle transmission does not recognize what gear it is in, a potential danger. Warning light appears randomly "shift to park" and vehicle will not shut down. Vehicle does not recognize that it is in park. Requires multiple attempts to manually shift gears. Multiple complaints for this issue found online. Contacted GM Customer Assistance and they are unresponsive to this problem. GM would not reimburse me for the repair and would not recognize this as a manufacturing problem (supposed to send $100 coupon to dealer, good for 1 year?) see 2 attachements

I own a 2017 Acadia Denali (purchased 10-4-17) We started having trouble with the vehicle in that a message appeared saying to shift the car into park. It would shut off but the lights and radio would stay on and you couldn't lock the vehicle. I took it to Ferman GMC in Wesley Chapel on May 28th of 2019. Supposedly they could not replicate the issue. The problem continued and we took it in again on May 31st of 2022. Again, they couldn't replicate what we were encountering. Now it's getting worse, happens almost every time we use the vehicle. So back to Ferman yet again (Oct 12th 2022). Now they are aware of said problem (code is b000a park switch circuit open). At this time they installed an SL-N-SWITCH and N-HARNESS at a cost of $63.13. Then labor, shop fees and taxes brought the total to $760.91, out of my pocket for a known problem. We have also come across a class action suit identifying this as a problem. And a TSB is also out there titled 'Vehicle displays shift to park message on DIC when in park. Vehicle may not shut off when put in park or may not start". There is a NHTSA ID number for this issue: 11353147

ON DECEMBER 29, 2020, I WAS GOING TO VISIT A FRIEND ABOUT 5:30PM. THEY HAVE A DRIVEWAY THAT IS A DOWNWARD SLOPE. I PUT MY CAR (2017 GMC ACADIA DENALI) IN PARK AND TURNED IT OFF. I STEPPED OUT AND LOCKED THE DOORS. I WAS TALKING TO MY FRIEND'S HUSBAND FOR A COUPLE MINUTES, ASKING IF SHE WAS HOME AND IF MY CAR WAS OKAY WHERE IT WAS PARKED. I WANTED TO MAKE SURE HE WAS NOT LEAVING AND WAS BLOCKED IN. I THEN STARTED WALKING TO THE HOUSE. I WAS GOING TO WALK IN THE GRASS AND JUST GO TO THE FRONT DOOR, BUT SINCE IT STARTED TO SNOW, I WALKED DOWN THE DRIVEWAY. MY VEHICLE THEN STARTED ROLLING DOWN THE DRIVEWAY AND KNOCKED ME OVER. IT PROCEEDED TO DRIVE OVER ME. I KNOW I FELL ON MY STOMACH, AS MY HANDS AND KNEES ARE PRETTY BRUISED AND SCRAPED UP. AS THE VEHICLE PROCEEDED TO KEEP GOING, I WAS PUSHED ON MY BACK WITH THE TIRE RESTING ON MY RIGHT HIP. THE GENTLEMAN RAN UP AND TRIED TO PUSH THE VEHICLE OFF OF ME, BUT COULD NOT PUSH IT UP HILL. LUCKILY THE KEYS AND MY PHONE FELL OUT OF MY POCKET AND HE WAS ABLE TO START THE VEHICLE AND DRIVE IT OFF OF ME. I KNOW AT SOME POINT I DID HIT MY HEAD, BECAUSE THE BACK IS REALLY TENDER TODAY. I DID GO TO URGENT CARE TO GET X-RAYS BECAUSE I DO NOT WANT TO GO TO THE HOSPITAL WITH ALL THE COVID CASES HERE IN ST JOSEPH COUNTY. THEY DID SCRUB ALL THE ROCKS AND DIRT OUT OF MY BACK AND HIP AND CLEANED UP MY KNEES. MY EX RAYS CAME BACK WITH NO BROKEN BONES AND I DID NOT HAVE BLOOD IN MY URINE, BUT THEY STILL RECOMMENDED THAT I GO TO THE EMERGENCY ROOM. I AM NOT ABLE TO WALK VERY WELL AND MY HIP IS VERY SWOLLEN. I CONTACTED THE DEALERSHIP BECAUSE MY CAR WAS JUST IN THE SHOP BECAUSE THE SHIFT TO PARK LIGHT KEPT COMING ON IN OCTOBER AND I HAVE MY REPAIR ORDER THAT SAYS THE PROBLEM WAS FIXED ON OCTOBER 22, 2020, WHICH OBVIOUSLY IT WAS NOT.

OUR CAR, A 2017 ACADIA, WILL NOT AUTO START, ALARMS GO OFF RANDOMLY, THEFT WARNING COMES ON AND HOOD OPEN WARNING COMES ON EVERY TIME CAR IS STARTED.. OUR DETERMINATION IS THE HOOD LATCH FROM OTHER FORUMS WHICH IS WHAT THE GARAGE ALSO DETERMINED. WE WERE TOLD ONLY TRUCKS WERE BEING REPLACED NOT THE CARS. WE DON'T FEEL THAT THIS IS SOMETHING WE SHOULD BE PAYING FOR SINCE IT IS OUT THERE THAT MANY HAVE THE PROBLEM. THE LATCH CAUSES THE THEFT PROBLEM WHICH EVENTUALLY CAUSES THE CAR NOT TO ADVANCE IN SPEED (CONNECTING TO THEFT) AND COULD CAUSE DEATH ON A MAJOR HIGHWAY WHEN ALL CARS ARE GOING 60 PLUS AND YOUR CAR WON'T MOVE. SOME PEOPLE WERE UNABLE TO START THEIR CARS. THIS IS MAJOR AND SHOULD BE CORRECTED WITH A RECALL. THIS MIGHT NOT SEEM MAJOR BUT IT CAN BE. WE BECAME LEERY IN DRIVING THE VEHICLE. I HAVE A TEEN DRIVER AND THE HOOD OPEN WARNING COMES ON MANY TIMES THROUGHOUT A DRIVE. YOU CAN CLEAR IT AND IT REAPPEARS WHETHER MOVING OR NOT. THIS HAS BEEN GOING ON WITH US FOR A GOOD MONTH. AGAIN, THIS HAPPENS WHILE STATIONARY AND MOVING. IT CAN COME ON AT ANY SPEED WHICH IS THE SCARY PART. WE HAVE LIMITED OUR DRIVE AND DRIVE AT A CONTROLLABLE SPEED BUT THAT DOESN'T MAKE IT SAFER. ONCE WE WERE STATIONARY WHEN THE ALARMS WENT OFF AND COULD NOT CLEAR. ALL THE WARNINGS CAME ON. COULDN'T UNLOCK CAR DOORS WITH REMOTE. WE SHOULD NOT HAVE TO PAY FOR THIS FIX! NO RECALL SHOULD HAVE TO HAVE A DEATH OR INJURY TO BECOME IMPORTANT!

SHIFT INTO PARK INDICATOR LIGHT COMES ON EVEN THOUGH IT HAS BEEN SHIFTED INTO PARK. CLUSTER WON'T SHUT OFF UPON EXIT.

SINCE I PURCHASED THIS VEHICLE I'VE HAD THE STABILITRAK, PARKING BRAKE, STEERING ASSIST WARNINGS POP UP ALONG WITH LIGHTS FLASHING AND THE CAR REDUCES POWER WHEN THIS HAPPENS. IF YOU RESET THE CODES, ITT STOPS. I'VE TAKEN IT BACK TO THE DEALER TO GET IT FIXED AND THEY DON'T KNOW WHAT'S WRONG WITH IT. I'VE HAD THIS VEHICLE 3 YEARS AND IT'S BEEN NOTHING BUT TROUBLE.

I BOUGHT MY 2017 GMC ACADIA ON AUGUST 3, 2020. WHEN I GOT HOME I PUT MY VEHICLE IN PARK AND ON THE SCREEN IT SAID "SHIFT TO PARK." I HAD PARKED ON A HILL AND I THOUGHT MAYBE THAT'S WHAT HAD CAUSED IT. SO FOR THE NEXT COUPLE WEEKS IT HAS DONE THE SAME THING MULTIPLE TIMES. I AM USUALLY PARKED AND SHIFTING IT INTO PARK. I HAVE BEEN LATE TO WORK BECAUSE I AM CONSTANTLY FIGHTING WITH THE SHIFTER SO MY CAR WILL SHUT OFF. I HAVE GOOGLED IT AND THERE A TON OF REVIEWS SAYING THAT THEY ARE HAVING THE SAME PROBLEM AS ME. I AM VERY DISAPPOINTED THAT NOTHING IS BEING DONE ABOUT THIS. I PAID A LOT OF MONEY FOR MY VEHICLE AND I'M MAKING A PAYMENT ON IT AS WELL. I HAVE TO SMALL CHILDREN AND IT'S A SAFETY HAZARD BECAUSE SOME HAS MADE COMMENTS THAT THEIR VEHICLE ROLLS BACKWARDS. SOMETHING NEEDS TO BE FIXED. SOME HAVE HAD IT FIXED AND TWO MONTHS LATER IT HAPPENS AGAIN. I HAVE CALLED THE GMC DEALERSHIP NEAR ME, CORPORATE, AND THE DEALERSHIP I BOUGHT IT FROM AND THEY ARE ALL LOOKING INTO THE PROBLEM. WE, AS IN THE PEOPLE THAT BOUGHT THE VEHICLE, SHOULDN'T HAVE TO PAY FOR A MISTAKE THE GMC CLEARLY KNOWS ABOUT.

THE 'SHIFT TO PARK' LIGHT COMES ON EVEN THOUGH MY CAR IS ALREADY IN PARK. I HAVE TO SIT THERE AND ROCK MY SHIFT BACK AND FORTH UNTIL THE WARNING LAMP GOES OFF. OTHERWISE I CAN'T TURN MY CAR OFF.

WHEN I PARK MY CAR, AND THE GEAR IS IN PARK, WHEN I TRY TO TURN THE CAR OFF, I RECEIVE CONTINUANCE NOTIFICATIONS STATING "SHIFT TO PARK" AND CAN NOT FULLY TURN THE VEHICLE OFF. THE ISSUE HAS BEEN CONTINUOUS AND AT TIMES CAN TAKE UP TO FIVE MINUTES BEFORE I CAN FULLY SHUT THE VEHICLE OFF. THE MOST RECENT EVENT WAS 9/17/2020. I HAVE SEVERAL VIDEOS OF THE ISSUE OCCURRING. THIS IS A KNOWN ISSUE WITH THE DEALERSHIP BUT THEY WILL NOT FIX IT ON THIS VEHICLE SINCE THERE IS NO RECALL AND IS OUT OF BUMPER-TO-BUMPER WARRANTY.

I GET AN ERROR MESSAGE WHEN TRYING PARK MY CAR STATING "ACTION REQUIRED, SHIFT TO PARK". DISPLAY SHOWS CAR IN PARK AND SHIFTING CONSOLE IN PARK. SOMETIMES TAKES ME MULTIPLE TIMES SHIFTING AND RESHIFTING, AND DRIVING BACK AROUND TO GET THE CAR TO SHUT OFF. THIS MORNING TOOK 15 MINUTES OF TRYING TO GET THE CAR TO PARK AND SHUT OFF.

I'M HAVING ISSUES OF GETTING AN ERROR MESSAGE ON MY DASHBOARD OF 'SHIFT TO PARK' WHEN THE SUV IS ALREADY IN PARK. I'VE HAD THIS RANDOMLY OVER THE PAST FEW WEEKS, BUT FIGURED I'D JUST MENTION IT TO THE DEALER AT THE NEXT APPT. GENERALLY, I RESTART IT, MOVE THE GEAR SHIFTER, AND THEN IT GOES INTO PARK. SATURDAY, THE GEAR SHIFTER SHOWED I WAS IN PARK, THE ERROR MESSAGE CAME ON, AND I STARTED ROLLING BACKWARDS! I WAS THANKFUL NO ONE GOT HURT, BUT I'M CONCERNED THAT ONE OF MY KIDS COULD HAVE BEEN BEHIND ME AND THIS HAPPEN. I PUT ON THE BREAK, HAD TO TURN OFF THE CAR, AND THEN RESTART IT, MOVE THE SHIFTER BEFORE IT WOULD RECOGNIZE BEING IN PARK.

THE VEHICLE DISPLAYS "SHIFT TO PARK" WHEN TURNING OFF VEHICLE EVEN THOUGH THE TRANSMISSION IS ALREADY IN PARK. WE HAVE TRIED MANY TIMES TO RESTART THE VEHCIE AND SHIFT THE VEHICLE. AS DESIGNED, THE KEYS MUST STAY WITH THE VEHICLE, SO THE OCCUPANT EITHER HAS TO LEAVE THE KEYS UNSECURED OR STAY WITH THE VEHICLE. I'VE HAD TO UNHOOK THE BATTERY BECAUSE THE ELECTRONICS WILL NOT SHUT OFF WHEN IN THIS STATE. WE HAVE HAD INSTANCES WHERE SOMEONE HAS TO STAY WITH THE VEHICLE FOR PERIODS OF TIME. AN ONLINE SEARCH SHOWS MANY COMPLAINTS ABOUT THIS ISSUE AND NO DEFINITIVE FIX.

THE HORN ON MY 2017 GMC ACADIA IS VERY HARD TO PUSH. IT TAKES BOTH HANDS. AND IS STILL VERY HARD TO PUSH. IF I HAD TO ACTIVATE MY HORN TO AVOID AN ACCIDENT, I WOULD NOT BE ABLE TO IN TIME. AND I HAVE TO TAKE BOTH OF MY HAND OF THE STEERING WHEEL TO PUSH IT. THIS IS A VERY BAD DESIGN AND SHOULD BE CORRECTED.

THE VEHICLE WILL SHOW TO BE IN PARK, BUT THE VEHICLE WILL SAY IT IS NOT IN PARK ENABLING ME FROM BEING ABLE TO SHUT THE VEHICLE DOWN. THERE SEEMS TO BE A SHIFT ASSEMBLY ISSUE. I'VE ONLY HAD THE VEHICLE 3 MONTHS BUT THIS HAS BECOME A REOCCURRING ISSUE OVER THE LAST WEEK.

PLACE THE VEHICLE INTO PARK. GO TO SHUT VEHICLE OFF AND THE DASH TELLS YOU TO SHIFT TO PARK. YOU HAVE TO KEEP SHIFTING IN AND OUT OF PARK TILL IT REGISTERS ITS IN PARK OTHER THE ELECTRONICS DON'T TURN OFF AND IF NOT PARKED ON LEVEL GROUND VEHICLE WILL ROLL. I PARK IN A PARKING GARAGE AND IF I WOULDN'T HAVE BEEN PAYING ATTENTION MY VEHICLE WHEN STARTING TO ROLL COULD HAVE EASILY HIT ANOTHER CAR OR EVEN WORSE A PERSON. MY VEHICLE IS GOING INTO SHOP TODAY SO IF DOCUMENTS ARE NEED I WILL HAVE THEM.

WHEN PUTTING VEHICLE IN PARK AND TRYING TO SHUT THE VEHICLE OFF THERE IS AN ERROR MESSAGE THAT COMES UP ON THE DISPLAY THAT SAYS TO PUT THE VEHICLE IN PARK. I HAVE TO TRY A COUPLE OF TIMES TO PUT IN PARK TO GET THE ERROR TO GO OUT SO I CAN SHUT THE VEHICLE OFF.

I BOUGHT A 2017 GMC ACADIA, AND HAVE NOT EVEN MADE A PAYMENT ON IT YET. IT JUST PASSED THE 36000 MILE MARK. I HAVE BEEN GETTING A SHIFT TO PARK WARNING EACH TIME I PARK TO SHUT OFF THE VEHICLE. THE VEHICLE SAYS IT IS IN PARK, BUT IT KEEPS SENDING THE WARNING. I HAVE TO PUT THE CAR IN REVERSE AND THEN DRIVE SEVERAL TIMES BEFORE IT WILL TURN OFF WITHOUT THE WARNING. *TR

WHEN THE VEHICLE IS PUT INTO PARK(STOPPED) AND TURNED OFF THE CAR DOES NOT RECOGNIZE THAT IT IS IN PARK. SO NOW IT SAYS "ACTION REQUIRED SHIFT TO PARK" (THE GEAR SHIFT IS IN PARK). THE ENGINE WILL BE OFF BUT THE LIGHTS, RADIO ANYTHING TIED TO THE BATTERY WILL NOT TURN OFF. THIS RUNS DOWN THE BATTERY IF YOU CANT GET THE CARD TO PARK. DEALER SHIP WILL NOT FIX

WHEN IN PARK, A 'SHIFT TO PARK' MESSAGE APPEARED AND I COULD NOT TURN OFF THE VEHICLE. HAD TO PUT VEHICLE IN GEAR AND TRY PUTTING IN PARK AGAIN. DID THIS SEVERAL TIMES AND THE ERROR MESSAGE WENT AWAY.

WHEN BEING PLACED IN PARK TO TURN OFF VEHICLE, MESSAGE STATES "SHIFT TO PARK". WHEN THIS HAPPENS I AM UNABLE TO LOCK DOORS, PARKING LIGHTS STAY ON AS WELL AS RADIO. IT TAKES SEVERAL ATTEMPTS TO GET IT TO NOT READ " SHIFT TO PARK". THIS HAPPENS VERY OFTEN.

THE CAR WILL NOT SHIFT TO PARK! IT SAYS SHIFT TO PARK! THIS IS BECOMING MORE AND MORE OF AN ISSUE. THE FIRST COUPLE OF TIMES I FIGURED IT MAY HAVE BEEN A FLUKE BUT LATELY IT IS ANYTIME THE CAR IS DRIVEN AND I NEED TO PARK.

PARK TO SHIFT WARNING WHEN TRYING TO SHUT OFF VEHICLE. PROBLEM "FIXED" 12/28/2108 BUT RESURFACED AGAIN OCTOBER 2020. NOW "OUT OF WARRANTY" MANY POSTS WITH OTHER OWNERS EXPERIENCING RECURRING ISSUE. DOES NOT SEEM TO BE A CONSISTENT FIX. NEW SHIFT MECAHNISM, NEW WIRING HARNESS AND "BENDING" THE METAL CONTACT POINT THAT DEPRESSES THE SWITCH TO ELIMINATE THE WARNING "LOCKOUT" ARE THE MOST COMMON FIXES. I BELIEVE THIS WIDESPREAD OF AN ISSUE SHOULD BE ADDRESSED BY GMC INSTEAD OF BURDENING OWNERS OF AFFECTED VEHICLES WITH THE COSTS OF "TRYING" DIFFERENT FIXES. THANK YOU

MY VEHICLE HAS BEEN NOTHING BUT TROUBLE SINCE I PURCHASED IT IN JUNE 2017. FIRST, THE CAR CAME WITH THE WRONG DOOR HANDLE ON ONE OF THE DOORS THAT TOOK 3 MONTHS TO FIX BECAUSE THE DEALERSHIP SCREWED UP THE PAINT ON THE DOOR AND HAD TO PAINT PRACTICALLY THE WHOLE CAR. AND INITIALLY THE DEALERSHIPS AND GMC CORPORATE GAVE ME THE RUNAROUND WITH WHO WAS PAYING FOR THE BILL WHICH THE CONSUMERS SHOULD NOT HAVE TO DEAL WITH. THEN THE CAR HAD A SHIFT TO PARK ISSUE IN JULY 2019 WHICH GMC WOULD NOT REPLACE AT THEIR COST EVEN THOUGH THEY RELEASED A NOTICE TO THE SERVICE DEPARTMENTS ABOUT IT BECAUSE A NUMBER OF PEOPLE WERE HAVING THE SAME ISSUE BUT NEVER ISSUED A TRUE RECALL NOTICE BECAUSE THEY WANTED THE CONSUMER TO GET STUCK WITH THE BILL. AND SINCE THEN I HAVE HAD ISSUES WITH MY MIRRORS NOT STAYING PROGRAMMED AND THE AIR VENTING AUTOMATICALLY SWITCHING TO LETTING AIR IN FROM THE OUTSIDE WITHOUT ME CHANGING IT. THEN MY CAR BATTERY STARTED GOING OUT FEBRUARY 2020 WHICH SHOULD NOT BE HAPPENING IN LESS THAN 3 YEARS OF THIS CAR BEING PURCHASED. AND NOW MY RADIATOR (WHICH IS ESTIMATED AT CLOSE TO $1,000 TO REPLACE) IS LEAKING; AGAIN THIS SHOULD NOT BE HAPPENING THIS SOON UNLESS THIS CAR IS A LEMON. GMC WON'T TAKE RESPONSIBILITY FOR ANY OF IT WITH THIS CAR AND THIS IS MORE PROBLEMS THAT ANYONE SHOULD EVER HAVE WITH A CAR WITHIN 3 YEARS OF PURCHASING IT BRAND NEW UNLESS IT IS A LEMON CAR WHICH AT THIS POINT, I THINK MINE IS.

VEHICLE WHEN SHIFT TO PARK WOULD INDICATE THE SHIFT WAS NOT IN PARK. WHEN I GOT THE VEHICLE NEW IS WHEN IT STARTED. I HAVE PUT UP WITH IT BY PRESSING HARD ON THE GEAR SHIFT AND CHECKING IT BEFORE TURNING THE CAR OFF.
