What 639 owners told NHTSA about the 2017 GMC Acadia Denali

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, WHEN PARKED, SHOWS A WARNING THAT STATES"ACTION REQUIRED:SHIFT TO PARK" AND THE VEHICLE WILL NOT TURN OFF. THIS HAS LED TO THE VEHICLE DYING IN PARKING LOTS, AT HOME, ONCE WHEN ON VACATION. THE SHIFT LEVER IS IN PARK, THE DASHBOARD SHOWS THAT IT IS IN PARK, AND WHEN THE ENGINE OFF BUTTON IS PRESSED THE VEHICLE WILL NOT TURN OFF AND ASKS THE DRIVER TO SHIFT THE CAR TO PARK, WHERE IT ALREADY IS. THIS HAS BEEN A HAZARD TO OUR FAMILY AND OUR FAMILIES HEALTH AS THE VEHICLE WILL THEN DIE EVENTUALLY BECAUSE THE BATTERY RUNS OUT. IT IS APPARENT THAT THERE IS A SEVERE MALFUNCTION IN THE ELECTRICAL/GEARBOX/COMPUTER SYSTEM NOT RECOGNIZING WHERE THE SHIFTER IS AT THE MOMENT. I WOULD LIKE TO ADD A PHOTO BUT IF I WERE TO TURN THE CAR ON TO TAKE THE PHOTO THE CAR LIKELY WILL NOT TURN OFF, AND THEN DIE ONCE AGAIN. THIS HAS BEEN ONGOING FOR APPROXIMATELY A MONTH TO 6 WEEKS. I WILL PUT THE DATE BELOW AS APPROXIMATELY JULY 4TH 2020.

BOTH REAR TIRES, MICHELIN TOTAL PERFORMANCE WITH 29,322 MILES ON THEM ARE LOSING CHUNKS OF RUBBER FROM THE TREAD. THE TREADS ARE NOT DOWN TO THE WEAR LINES.

WITH VEHICLE PARKED I GET A MESSAGE OF SHIFT IN PARK AND VEHICLE DOESN'T FULLY TURN OFF. IT IS KNOWN AS AN ISSUE FOR GM VEHICLES - BULLETIN ISSUED.

NHTSA ODI 11350769

WHENEVER I SHIFT THE VEHICLE TO PARK AND TURN OFF THE ENGINE, A MESSAGE IS DISPLAYED THAT SAYS 'ACTION REQUIRED SHIFT TO PARK.' IT DOES NOT RECOGNIZE THAT THE VEHICLE IS IN PARK AND THEREFORE WILL NOT LET ME LEAVE THE VEHICLE. SOMETIMES I HAVE TO TURN THE VEHICLE ON AND OFF SEVERAL TIMES AND SHIFT BACK-AND-FORTH FROM DR. TO PARK SEVERAL TIMES BEFORE I CAN GET OUT OF THE CAR. I HAVE TAKEN IT TO THE DEALER TWICE NOW. THE FIRST TIME THE FIX DIDN'T WORK AND THE SECOND TIME WAS JUST YESTERDAY SO TIME WILL TELL.

NHTSA ODI 11350748

ALTHOUGH IN PARK, THE DASH ALERTS THE FOLLOWING MESSAGE : 'SHIFT TO PARK' THIS ALERT DOES NOT ALLOW THE VEHICLE TO BE SHUT OFF FULLY AS THE RADIO STILL PLAYS, LIGHTS REMAIN IN AND THE DASH REMAINS LIT. HAVE TRIED TO RESTART AND SHIFT INTO DIFFERENT GEARS THEN RETURN TO PARK AS WELL AS ENGAGE THE EMERGENCY BREAK. NOTHING WORKS TO FIX THIS.

NHTSA ODI 11350515

STARTING VEHICLE AFTER 10 HOURS OF VEHICLE NOT RUNNING, THE VEHICLE CRANKS/HAS A DELAYED START FOR APPROXIMATELY 4 TO 8 SECONDS. BATTERY, ALTERNATOR AND START WAS CHECK AND ALL WAS IN WORKING ORDER. I WAS TOLD THE ISSUE MAY BE A DEFECTIVE FUEL PUMP, DUE TO THE ENGINE LOSING FUEL PRESSURE AFTER NOT RUNNING FOR AN EXTENDED PERIOD OF TIME.

NHTSA ODI 11350142

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.

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.

THIS IS THE 2ND TIME, FIXES IN MARCH 2019. NOW HAVING SAME PROBLEM. WHEN I PUT THE SUV IN PARK I GET AND ERROR MESSAGE 'SHIFT TO PARK'. ACCORDING TO GMC THERE IS A TECHNICAL SERVICE BULLETIN ISSUED BUT NO RECALL. OF COURSE DEALER WILL NOT COVER COST SINCE IT WAS REPAIRED OVER A YEAR AGO. VEHICLE WAS OUT OF WARRANTY ALREADY SO I ALREADY PAID OVER $330 TO HAVE REPAIRED ONCE. GMC WILL OFFER NO HELP. SOMETIMES TAKES ME AS MANY AS 10 TIMES TURNING VEHICLE ON AND OFF BEFORE I CAN GET THE VEHICLE TO CLEAR THE MESSAGE.

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.

MY 2017 GMC ACADIA WITH 40,000 MILES ON IT HAS BEEN SAYING 'SHIFT TO PARK' WHEN I TRY TO TURN IT OFF. THE ONLY WAY TO GET IT TO TURN OFF AND BE SAFELY IN PARK IS TO CONTINUOUSLY TURN IT BACK ON SHIFT TO REVERSE OR DRIVE MOVE THE CAR A FEW FEET AND TRY AGAIN. IT CONTINUES TO TAKE MULTIPLE TIMES AND THE ONLY THING TO 'FIX IT' GMC CLAIMS IS TO REPLACE A LEVER AND THAT TAKES 5-6 HOURS AT 135$ AN HOUR AND 2 150$ PARTS. IT IS NOT COVERED UNDER WARRANTY AND IS A HUGE SAFETY ISSUE AS YOU EITHER CANNOT GET THE VEHICLE INTO PARK AND HAVE IT SAFELY STUCK OR IT WILL CONTINUE TO STAY ON AND POSSIBLE ROLL AWAY. THERE ARE HUNDREDS OF THOUSANDS OF FORUMS AND POSTS ABOUT THIS ISSUE AND EVEN THE PEOPLE WHO GOT IT 'FIXED' STILL HAVE ISSUES. IT IS A SAFETY ISSUE AND GMC NEEDS TO FIGURE OUT WHAT IS CAUSING IT HOW TO FIX IT AND DO AN EMERGENCY RECALL IF THEY CANNOT FIGURE IT OUT THEN THEY NEED TO FULLY RECALL THE 17-18 ACADIAS AND PROVIDE REPLACEMENT VEHICLES AS THIS IS A MAJOR SAFETY RISK. I CANNOT BE STUCK AT A PLACE DURING A GLOBAL PANDEMIC BECAUSE MY CAR IS STUCK DUE TO AN ISSUE THAT GMC CANNOT FIX.

THE DEALERSHIP AGAIN REPLACED THE SHIFTER, (THAT SHORTED OUT) AND THIS TIME INSTALLED A WIRING HARNESS THAT HAD A RESISTER INSTALLED IN THE HARNESS TO PREVENT DAMAGED TO THE SHIFTER ASSEMBLY FROM THE OVER CURRENT THAT GOES TO THE SHIFTER.

1. THE BATTERY TOTALLY DIES AFTER SITTING FOR 3 DAYS. 2. SOMETIMES A WARNING MESSAGE APPEARS "SHIFT INTO PARK" WHEN THE SHIFTING HANDLE IS IN PARK AND SOMETIMES PREVENTS TURNING THE ENGINE OFF. SOMETIMES AFTER TRYING SEVERAL TIMES IT STOPS THE ENGINE BUT DASH LIGHTS REMAIN ON. DEALERSHIP SAYS THIS IS A COMMON PROBLEM AND THEY DO NOT HAVE A DEFINATIVE SOLUTION.

WITH VEHICLE STATIONARY, I ATTEMPTED TO PLACE THE TRANSMISSION IN "PARK" AND TURN OFF THE VEHICLE. THE DASHBOARD INFORMATION SCREEN DISPLAYED THE MESSAGE "SHIFT TO PARK" AND WOULD NOT ALLOW THE VEHICLE TO FULLY SHUT DOWN (HEADLIGHTS REMAINED ON) EVEN THOUGH THE SHIFT KNOB WAS IN "PARK" AS WELL AS "P" DISPLAYED ON THE DASHBOARD SCREEN. THE ELECTRONIC EMERGENCY BRAKE WAS INOPERABLE AND THE VEHICLE SEEMED TO BE AT RISK OF ROLLING AWAY. THIS LEFT ME STRANDED WITH THE VEHICLE AND UNABLE TO REMOVE MYSELF FROM IT.

NHTSA ODI 11340425

I HAD A DRIVER SEATBELT MALFUNCTION RIGHT AFTER I PURCHASED THE VEHICLE. I NOW HAVE A SECOND ROW, DRIVERS SIDE SEAT BELT MALFUNCTION. THEY HAVE NOT BEEN ABLE TO REPAIR OR REPLACE THE SEATBELT FOR OVER A YEAR. I WAS TOLD AT THE DEALERSHIP THAT THEY WERE REDESIGNING THE SEAT BELT. THEY WOULD CALL ME WHEN IT WAS AVAIL, AND ALSO THAT IT IS NOT UNDER WARRANTY. STILL NO SEATBELT.
