What 639 owners told NHTSA about the 2017 GMC Acadia Denali

THE FIRST PROBLEM I HAD WAS THE SHIFT. I GOT IT FIXED. I HAVE IT ALL DOCUMENTED. NOW FOR THE SECOND TIME IN THE PAST 2 WEEKS MY CAR HAS FLASHED EVERY WARNING LIGHT POSSIBLE. I TOOK IT IN THE FIRST TIME AND WAS TOLD THE CODES DID NOT STORE AND TO KEEP DRIVING IT. I FINALLY GOT A VIDEO OF THE PROBLEM HAPPENING AND DROPPED IT OFF FOR A SECOND TIME. DURING THE PROBLEM ALL GAUGES GO TO ZERO AND THE GEAR SYMBOL DISAPPEARS. THE LAST TIME I DROVE THE CAR IT ACCELERATED ON ITS OWN AND I DID NOT HAVE CONTROL OF THE VEHICLE. *TR

SOMETIMES WHEN I SHIFT INTO PARK AND TURN OFF THE VEHICLE I GET A MESSAGE THAT SAYS "SHIFT INTO PARK". IT IS ABSOLUTELY IN PARK! AT THAT POINT I HAVE TO RESTART THE VEHICLE, TAKE IT OUT OF PARK AND PUT IT INTO REVERSE AND THEN PUT IT BACK INTO PARK. THIS DOES NOT HAPPEN EVERYDAY BUT QUITE FREQUENTLY. *TR

THE CAR WOULD BE STATIONARY. I WOULD PUT IT IN PARK AND THEN TURN OFF THE CAR. THE DASH DISPLAY SHOWED AN ERROR THAT THE CAR WAS NOT IN PARK, EVEN THOUGH IT WAS. THE CAR WOULD NOT COMPLETELY TURN OFF BECAUSE OF THIS. I TURN THE CAR ON AND OFF MULTIPLE TIMES, SHIFTING IN AND OUT OF PARK. ONE TIME, THE CAR HAD TO BE TURNED ON AND OFF 10 TIMES BEFORE IT FINALLY REGISTERED THAT IT WAS IN PARK. THE CAR IS STATIONARY THE WHOLE TIME DURING THIS PROCESS. EVENTUALLY, THE CAR WOULD REGISTER THAT IT WAS INDEED IN PARK AND COMPLETELY TURN OFF AS DESIRED. THIS WOULD HAPPEN ALMOST EVERY TIME THE CAR WAS DRIVEN AND THEN PARKED. I CALLED MY LOCAL GMC DEALERSHIP EXPLAINING THIS. THE SERVICE SUPERVISOR SAID THIS HAS BEEN A COMMON ISSUE WITH THE SHIFTER/TRANSMISSION CONTROLLER ON ACADIAS OF MY YEAR MODEL. MY DEALERSHIP DID NOT HAVE THE REQUIRED PARTS/HARNESS IN STOCK SO WE HAD TO WAIT A WEEK AND A HALF FOR THEM TO BE DELIVERED. THE DATE LISTED IS THE DAY I CALLED THE DEALERSHIP. THE ISSUE DESCRIBED HAD BEEN GOING ON FOR 3-4 DAYS PREVIOUS TO CALLING. ATTACHED IS A PORTION OF MY RECEIPT PERTAINING TO THIS ISSUE.

THE CAR WILL NOT TURN OFF AND REPORTS ON THE DASHBOARD DISPLAY 'SHIFT TO PARK' EVEN THOUGH THE SHIFTER IS IN PARK. TRUCK WILL ROLL WHEN IT SHOULDN'T BE POSSIBLE. ALSO, UNLESS YOU CAN GET IT TO ACKNOWLEDGE YOU'RE IN PARK, HEADLIGHTS AND ALL ACCESSORIES STAY ON. AN ALARM SOUNDS IF YOU LEAVE THE VEHICLE. IT'S A MESS AND ALTHOUGH GMC KNEW ABOUT THE ISSUE IN MID 2018, REFUSES TO FIX IT WITHOUT PAYMENT. THIS SHOULD BE A MANDATORY RECALL.

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.

ON SATURDAY, APRIL 11, 2020 THE EBCM, ELECTRONIC BRAKE CONTROL MODULE, SET OFF A PARKING BRAKE DASHBOARD LIGHT CAUTION. THE PARKING BRAKES NO LONGER ENGAGED. BELIEVING IT WAS A CERTIFIED WARRANTY ISSUE, I HAD IT REPAIRED, APRIL14, 2020, AT BURDICK CHEVY GMC BUICK. TURNS OUT IT IS CONSIDERED A 'WEARABLE PART' AND NOT COVERED. TWO DAYS LATER, APRIL 16, 2020, I DISCOVERED THE EBCM MODULE RECALL ON SIMILAR VEHICLES, ATTACHED AP ARTICLE. SINCE APRIL 16 UNTIL APRIL 23, I ATTEMPTED WORKING WITH GMC, AND THE DEALER, OBTAINING REIMBURSEMENT TO NO AVAIL. THEREFORE AFTER READING THE THE ARTICLE, THE DEALERSHIP, AND FOUR DIFFERENT GMC REPRESENTATIVES, I REQUEST AN INVESTIGATION WHETHER THIS EBCM MODULE ISSUE IS THE SAME AS THE ARTICLE. THANK YOU.

SECOND TIME INTO THE DEALERSHIP FOR THE SAME THING IN ONE YEAR. THE "SHIFT TO PARK" WARNING POPS UP AFTER I STOP AND PUT THE SHIFTER INTO PARK. HOWEVER, IT DOES NOT RECOGNIZE THAT FACT. THE VEHICLE THINKS IT IS ANOTHER GEAR. EVEN AFTER GETTING OUT, MY RADIO STAYS ON AND AND MY HORN HONKS AS A WARNING. I TRIED TO LOCK THE DOOR AND IT UNLOCKS ITSELF IMMEDIATELY. MULTIPLE STARTING AND STOPPING ONLY WORKS ON OCCASION. TWO LOST DAYS TO THE REPAIR SHOP. IF I DIDN'T HAVE AN EXTENDED WARRANTY ON THIS LATEST PROBLEM, THIS VISIT YESTERDAY WOULD HAVE COST ME OVER $500! I FEAR THIS WILL BE A REPEATING ISSUE .

SHIFT TO PARK - THIS IS ROUND TWO (2) THAT THIS HAS HAD TO BE REPLACED!! THIS IS ROUND TWO (2) OF TRANSMISSION CONTROL REPLACEMENT - WHICH WORRIES ME THAT OTHER TRANSMISSION ISSUES WILL OCCUR. ACADIA IS "CLEARLY" IN PARK - AND YES I LEARNT YOUR LITTLE TRICK TO WIGGLE AND OR TOUCH THE +/- BUTTON ON TOP OF THE SHIFT STICK TO GET IT TO COMPREHEND THAT IT IS INDEED IN PARK. BUT THAT ONLY WORKED A TOTAL OF THREE (3) TIMES. FIRST TIME WAS IN A PARKING LOT THAT THIS OCCURRED - SECOND TIME IN A GAS STATION. HAVING TO RESTART YOUR VEHICLE AND SHUT IT OFF 10 TIMES JUST FOR IT TO ACKNOWLEDGE IT IS IN PARK - IS HUMILIATING TO SAY THE LEAST WHEN YOU ARE AT A GAS STATION AS WELL AS FRUSTRATING. YOU NEED NOT TO IGNORE THIS - AS THE FIRST TIME I COULD NOT GET OUT OF THE VEHICLE. SECOND TIME - I WAS ABLE TO - HOWEVER IF ONE IGNORES IT WILL END UP DRAINING THEIR BATTERY AND/OR ROLLING IF YOU ARE ON AN INCLINE. KINDLY STEP FORWARD AND FIX THIS ISSUE IF YOU WANT SATISFIED CUSTOMERS. AS I CAN PUT ONLY ONE DATE - I PUT THE FIRST ONE 01/13/2020 SECOND REPLACEMENT 03-21-2020 27,109 MILES. THANK YOU.

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.

MY VEHICLE IS RECEIVING A "SHIFT TO PARK" ERROR WHEN THE VEHICLE IS PLACED IN PARK. THE SYSTEM DOES NOT REGISTER PARK, THEREFORE DOESN'T SHUT OFF AND CAN'T BE LOCKED OR VACATED. IT TAKES MULTIPLE ATTEMPTS TO GET IT INTO PARK. THERE IS A KNOWN ISSUE IN GM SERVICE BULLETIN 18-NA-297 BUT GMC HAS NOT RECALLED THIS DANGEROUS SHIFTER AND MY VEHICLE IS FAULTY.

RANDOMLY WHEN THE CAR IS PUT INTO PARK AND THE BUTTON IS PRESSED TO STOP THE ENGINE A MESSAGE COMES UP ON DASHBOARD STATING SHIFT TO PARK... SOMETIMES YOU CAN WIGGLE THE GEAR SHIFT AND THE MESSAGE GOES AWAY, SOMETIMES YOU MUST START, MOVE, AND STOP THE CAR AS MANY AS 15 TO 20 TIMES TO GET THIS TO GO AWAY. IF YOU EXIT THE CAR WHY THE MESSAGE IS ON DASHBOARD, THE HORN WILL CHIRP AT YOU, AND THE VEHICLE IS NOT STABLE, IF IT IS ON A DECLINE IT WILL ROLL, THE RADIO STAYS ON ETC. I FOUND A GM SERVICE BULLETIN REGARDING THIS, STATING THE PART TO BE REPLACED FOR THE ACADIA WAS 13528228. I HAVE SCHEDULED AN APPT WITH THE LOCAL GM DEALER TO HAVE THIS LOOKED AT. IT COULD POTENTIALLY BE VERY DANGEROUS GIVEN THE RIGHT SCENARIO, IF A KID OR SOMEONE HOPPED OUT OF THE CAR AND IT WASNT IN PARK. THE CAR HAS 36,000 MILES ON IT.

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.

I ATTEMPT TO PLACE MY ACADIA INTO PARK AND POWER DOWN MY VEHICLE ONLY TO GET A "SHIFT TO PARK" ERROR MESSAGE. I AM UNABLE TO POWER DOWN MY VEHICLE AND NOT FULLY PARK MY VEHICLE EVEN THOUGH I HAVE PARKED IT. THIS OCCURS DAILY AND HAS OCCURED 15-20 TIMES IN 1 ATTEMPT TO PARK. I HAVE TO ATTEMPT TO TURN CAR BACK "ON" AND THEN PUT CAR INTO DRIVE OR REVERSE DRIVING ABOUT A FOOT OR SO THAN ATTEMPT TO REPARK MY VEHICLE. ONLY TO HAVE TO REPEAT THIS STEP OVER AND OVER TIL IT FINALLY DISAPPEARS. GMC CUSTOMER SERVICE ASSOCIATE CLAIMS THEY ARE UNAWARE OF THE ISSUE. OF COURSE THIS ISSUE ONLY OCCURRED AFTER MY VEHICLE WARRANTY EXPIRED.

WHEN SHUTTING DOWN THE VEHICLE A "SHIFT TO PARK" MESSAGE APPEARS ON THE CONSOLE AND THE ELECTRICAL SYSTEM DOES NOT SHUT DOWN. IN ORDER TO CLEAR THE PROBLEM, THE VEHICLE MUST BE RESTARTED AND THE SHIFTER MOVED BETWEEN GEARS AND BACK TO PARK, SOMETIMES SEVERAL TIME BEFORE SUCCESSFULLY SHUTTING DOWN. DEALER SAID THAT EVEN THOUGH THE CAR HAD ONLY 35000 MILES ON IT, IT WASN'T COVERED UNDER WARRANTY AS THE VEHICLE HAD BEEN IN SERVICE MORE THAT 36 MONTHS. CHARGED ME $590.00 TO REPLACE THE SHIFTER ASSEMBLY. OPENED A CASE WITH GMC, BUT THEY DECLINED TO DO ANYTHING ABOUT IT.

SHIFT TO PARK PROBLEM, THE DEALER TRIED FIXING IT 3 TIMES NOW AND HAVING A PROBLEM WITH THE WHEEL. WHEN SOMETIMES TURNING THE CAR. I CAN FEEL SOMETHING IS LIKE STOCK ON TGE WHEEL MAKING ME FEEL LIKE THE WHEEL IS GONNA GET OFF. I TRUED CONTACTING THE DEALER AND CHEVY OFFICE FOR A BUYBACK BUT THEY AREN'T APPROVING IT COS THEY SAID I DONT HAVE ENOUGH REASON FOR THEM TO APPROVE IT. EVEN THO I KEEP TELLING THEM I AM NOT GONNA WAIT FOR ANYTHING BAD TO HAPPEN SINCE I HAVE A 5 MONTH OLD BABY WITH ME. TGE OBLY THING THEY SUGGESTING IS HAVING IT CHECKED. AND THAT'S IT.

BETWEEN 1300-1500 RPM THERE IS A HESITATION FOR ACCELERATION. IT SEEMS THE TRANSMISSION SHUDDERS AT THIS RPM AT DIFFERENT SPEEDS. THIS WILL BE THE SECOND TIME THE VEHICLE HAS BEEN TO THE DEALERSHIP WITH THIS COMPLAINT. THE 1ST TIME THIS OCCURRED THE TECHNICIAN REPORTED THE CAR WAS SEVERAL BULLETINS BEHIND AND WAS BROUGHT CURRENT. THIS DID NOT RESOLVE THE ISSUE. IF ANYTHING THE ISSUE BECAME MORE NOTICEABLE. A BRAKE SENSOR AND GAS PEDAL ASSEMBLY HAVE ALSO BEEN REPLACED DUE TO DEFECT.
