WHEN THE VEHICLE IS ALREADY IN MOTION, IT AUTOMATICALLY SHIFTS OUT OF DRIVE AND I AM LEFT IN THE MIDDLE OF THE ROAD UNABLE TO ACCELERATE FOR A FEW SECONDS UNTIL THE VEHICLE AUTOMATICALLY SHIFTS BACK TO DRIVE. THIS HAPPENS AFTER PULLING OUT OF MY GRAVEL DRIVEWAY WHICH IS A SLIGHT INCLINE, AND ONTO A HIGHWAY. THE CAUSE IS UNKNOWN. *TR
TL* THE CONTACT OWNS A 2020 GMC ACADIA. THE CONTACT STATED THAT WHILE DRIVING AT 15 MPH, WITHOUT WARNING THE PARKING BRAKE ENGAGED INDEPENDENTLY. THE CONTACT MANUALLY RELEASED THE PARKING BRAKE AND THE VEHICLE OPERATED AS INTENDED. DEALER RUSTY WALLACE KIA LOCATED AT (300 KING AVE, MORRISTOWN, TN 37814, (800) 458-0302) WAS CONTACTED AND INFORMED OF THE FAILURE. AN APPOINTMENT WAS SCHEDULED TO HAVE THE VEHICLE DIAGNOSED WHICH WAS STILL PENDING. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE, BUT NO FURTHER ASSISTANCE WAS PROVIDED. THE FAILURE MILEAGE WAS APPROXIMATELY 6,276.
DRIVING ALONG NO ISSUES, CAR SAYS 60 MILES TO EMPTY NO FUEL WARNING LIGHT OR ANYTHING, WHEN CAR JUST SUDDENLY LOSES POWER, WAS ABLE TO GET TO SIDE OF ROAD. TOLD ME TO RESTART ENGINE, AND IT WOULDNT FIRE BACK UP. PUT A GALLON OF GAS IN AND IT FIRED BACK UP. OWNED CAR FOR ALMOST 3 WEEKS CANT BELIEVE THERE WAS NO INDICATION FUEL WAS APPARENTLY THAT LOW. 60 MILES TO EMPTY SHOULD HAVE BEEN ABLE TO FINISH THE 2 MILES I HAD ON MY DRIVE TO WORK AND TO GET GAS.
PURCHASED NEW 2020 GMC ACADIA DENALI IN DEC 2019. VEHICLE WAS EQUIPPED WITH SEVERAL DEALER ACCESSORIES INCLUDE ROOF RAIL CROSS-BEAMS. THESE WERE NOT IN STOCK AT TIME OF PURCHASE AND RETURNED AFTER 1 WEEK TO INSTALL. AFTER PICKING UP THE VEHICLE ON MY DRIVE HOME, I HEARD A WHISTLING/HUMMING NOISE COMING FROM THE EXTERIOR AT ABOUT 30 MPH. AS I ENTERED THE HIGHWAY AND TRAVELING AT 65 MPH, THE NOISE WAS DEAFENING AND THE VEHICLE DID NOT HANDLE VERY WELL, VIBRATION IN THE STEERING. I IMMEDIATELY RETURNED TO THE DEALER AND DETERMINED THE NOISE WAS FROM THE ROOF RAIL CROSS-BEAMS. SERVICE TEAM THAT THERE COULD BE SOME NOISE BUT IT WOULD NOT AFFECT THE VEHICLE HANDLING. I HAD THEM REMOVED AND THE DRIVE HOME HAD NO ISSUES. BUYER BEWARE IF YOU ARE ONLY GETTING THE CROSS-BEAMS AS AN ADDED ACCESSORY AND WILL NOT UTILIZE TO CARRY ANY ITEMS, IE; KAYAK, BIKES, ETC.
TWO DAYS AFTER PURCHASING A NEW 2020 GMC ACADIA I GET AN ERROR ON THE DISPLAY "SD CARD REMOVED" ALONG WITH VARIOUS OTHER ERROR MESSAGES. DEALER TALKS TO GMC TECH LINE AND THEY ADVISE TO REPLACE RADIO. RADIO WAS REPLACED AND ERRORS BEGAN SAME DAY I PICKED IT UP. DEALER IS REPLACING RADIO AGAIN, BUT UNSURE IF THIS WILL FIX THE ISSUE. THE VEHICLE DOES NOT WORK AS INTENDED AS WHEN YOU PRESS THE NAV BUTTON VARIOUS ERROR MESSAGES POP UP AND NAVIGATION DOES NOT WORK.
RECENTLY PURCHASED A 2020 ACADIA DENALI. WHEN PARKING AT ANY INCLINE THE PARKING BRAKE AUTOMATICALLY TURNS ON. DEALER IS NOT SURE WHY, BUT NO WHERE IN THE MANUAL DOES IT STATE THIS IS NORMAL. TO DISENGAGE BRAKE VEHICLE HAS TO BE PUT IN GEAR WITH FOOT ON BRAKE TO TURN OFF. THE PARKING BRAKE SHOULD TURN OFF WHEN VEHICLE IS IN PARK WITH FOOT ON BRAKE BUT IT DOES NOT. DEALER IS UNSURE OF ISSUE AND HAS AN OPEN CASE WITH GMC TO INVESTIGATE.
NHTSA publishes every complaint as the owner wrote it and investigates only a fraction. Spelling, capitalisation and judgement are the filer’s own. What carries weight is repetition: the same component failing the same way across many filings, and whether the manufacturer eventually opened a recall for it.
