What 639 owners told NHTSA about the 2017 GMC Acadia Denali

THE HORN IS VERY HARD TO HONK. IT TAKES MY WIFE BOTH HANDS TO ACTIVATE THE HORN. I HAVE SEEN SIMILAR COMPLAINTS ON THE COMPUTER. I HAVE BEEN BACK AND FORTH WITH A GM REPRESENTATIVE FOR ABOUT 5 MOTHS AND HAVE GOTTEN NOWHERE. THEY APPARENTLY DO NOT SEE THIS AS A SAFETY CONCERN. I DO. I HAVE TAKEN THE CAR BACK TO THE DEALER AND THEY SAID THEY ADJUSTED THE HORN, BUT THERE WAS NO IMPROVEMENT. WE CHECKED 3 OTHER ACADIAS ON THE LOT, AND THEY ALL HAD THIS PROBLEM.

HARMONIC VIBRATION AT AROUND 1500 RPM WHILE HOLDING SPEED ANY GEAR OR MPH

HORN BUTTON ON STEERING WHEEL IS VERY DIFFICULT TO DEPRESS TO ACTIVATE. USUALLY TAKES TWO HANDS TO ACTIVATE OR DEPRESS. IN A SITUATION THAT REQUIRES HORN USAGE THIS IS NOT A SAFE ACTIVATION USAGE.

THE HORN IS EXTREMELY DIFFICULT TO ACTIVATE. A PERSON MUST USE EXTREME WEIGHT AND PRESSURE TO GET THE HORN TO WORK. DEALERSHIP TOLD ME THAT I AM NOT THE FIRST PERSON TO COMPLAIN ABOUT THE ISSUE BUT AS OF YET THERE IS NO REPAIR THAT THEY HAVE TO FIX THE PROBLEM. THIS OCCURS NO MATTER WHETHER THE VEHICLE IS MOVING OR PARKED. THIS HAS HAPPENED EVERY SINCE THE VEHICLE WAS NEW. THE PROBLEM OCCURS EVERY TIME I TRY TO ACTIVATE THE HORN.

THE 2017 GMC ACADIA HORN TAKES AN UNREASONABLE AMOUNT OF FORCE TO ENGAGE. THIS HAS BEEN NOTED BY SEVERAL USERS. MY SPOUSE HAD A SEMI TRUCK COME INTO HER LANE A DAY AGO AND COULD NOT GET HORN TO SOUND TO WARN OTHER DRIVER. GMC DEALERSHIP INVESTIGATED AND SAID ITS JUST THE WAY THE ASSEMBLY WORKS IN THIS MODEL. I BELIEVE THIS REPRESENTS A SAFETY ISSUE AS IT MAKES THE HORN UNUSABLE WHEN YOU NEED IT QUICKLY AND WITHOUT TAKING YOUR EYES OFF THE ROAD. GM IS SAYING TO BAD.

THE GAS GAUGE INDICATOR SHOWED 90 MILES UNTIL EMPTY, BUT WAS ACTUALLY EMPTY. THIS OURRED DURING A FAMILY TRIP FROM NORTHERN CALIFORNIA TO SOUTHERN CALIFORNIA. WE RAN OUT OF GAS ON TOP OF THE GRAPEVINE. FINALLY, AFTER A 3 HOUR WAIT, ROAD SERVICE BROUGHT GAS AND WE WERE ON OUR WAY TO THE NEAREST GAS STATION.

WHEN THE VEHICLE AUTOMATICALLY GOES INTO V4 MODE THERE IS A VIBRATION INSIDE THE CABIN. THE VIBRATION ALSO SOUNDS LIKE A BOOM NOISE INSIDE THE CABIN AND THE VEHICLE SHAKES WHILE DRIVING. THE PROBLEM SEEMS TO OCCUR AT 1500-1700 RPMS AND WILL CONTINUE UNTIL YOU ACCELERATE AND MAKE THE VEHICLE GO BACK INTO V6 MODE. DEALER ATTEMPTED TO FIX THE PROBLEM ON 2 OCCASIONS BUT WAS UNABLE TO. DEALER ACKNOWLEDGED THE PROBLEM AND CATEGORIZED IT AS A VIBRATION, DRONE, FLUTTER OR BOOM NOISE INSIDE THE CABIN WHILE VEHICLE IS IN AFM V4 MODE. PROBLEM HAS NOT BEEN FIXED.

MY 2017 GMC ACADIS 6 CYLINDER AWD HAS EXCESSIVE VIBRATIONS THAT OCCUR AT 1400-1600 RPM AND AT VARIOUS SPEEDS.IT SEEMS LIKE THE TRANSMISSION REFUSES TO SHIFT AND IT LASTS FOR UP TO A QUARTER MILE.VIBRATION IS MOST PRONOUNCED AT SPEEDS OF 55-60 MPH THE DEALER DIAGNOSIS SAYS IT IS FUNCTIONING NORMAL. THE STRUTS WERE REPLACE AT1390 MILES AND MOTOR MOUNTS ADJUSTED, PROBLEM REMAINS, AUTO BROUGHT TO DEALER FOR RECALL AS PER BULLETIN 17109 BUT IT STILL VIBRATES EXCESSIVELY. THE LEAD MECHANIC AT THE DEALERSHIP SAID THE AUTO ADJUSTS TO THE DRIVER AND SAID THE VIBRATIONS WILL STOP AT ABOUT 2500 MILES. THE CAR NOW HAS 2900 MILES AND IT STILL FEELS LIKE THE TRANSMISSION IS GOING TO FAIL. THE VIBRATION IS UNCOMFORTABLE AND ALTHOUGH THE DEALERSHIP SAID THE CAR IS SAFE IT DOES NOT FEEL SO.IT SEEMS IMPOSSIBLE FOR A VEHICLE TO BE FUNCTIONING PROPERLY WITH THIS CONTINUAL ERRATIC VIBRATIONS.

TL* THE CONTACT OWNS A 2017 GMC ACADIA. WHILE DRIVING VARIOUS SPEEDS, THE TRANSMISSION HESITATED TO SHIFT GEARS AND THE VEHICLE BEGAN TO VIBRATE EXCESSIVELY. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE CONTACT REFERENCED GMC RECALL NUMBER 17109 (REAR DIFFERENTIAL CLUTCH CONTROL MODULE). THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE STRUTS AND THE MOTOR MOUNT NEEDED TO BE REPLACED. ADDITIONALLY, FIELD TESTERS DETERMINED THAT THE VEHICLE WAS OPERATING NORMALLY. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT DID NOT ASSIST. THE MANUFACTURER STATED THAT THE VEHICLE WAS OPERABLE. THE APPROXIMATE FAILURE MILEAGE WAS 209,000.

THE STEERING HAS LOCKED BRIEFLY 3 TIMES WHILE DRIVING ON THE FREEWAY WITHIN THE LAST FEW WEEKS. THE FIRST TIME I WAS CHANGING LANES ON I-8 GOING ABOUT 45 MPH. THE NEXT TIME I WAS TAKING A FREEWAY EXIT RAMP FROM I-805 TO THE I-8 DECELERATING AND HAD NO CONTROL AS I TURNED THE WHEEL TO MANEUVER THROUGH THE CURVE. THIS PAST SATURDAY, 4/8, I WAS EXITING I-805 AT SORRENTO VALLEY ROAD AND THE STEERING LOCKED FOR OVER 2 SECONDS. I ORIGINALLY THOUGHT THIS WAS A SUSPENSION ISSUE. HOWEVER, I FINALLY RECEIVED SERVICE RECORDS FROM HOEHN GMC IN CARLSBAD ON 4/7 THAT STATED THERE WAS AN ISSUE WITH THE VEHICLE BEFORE I TOOK DELIVERY. THE SERVICE RECORD STATES '40 DTC P16E5 SENSOR COMM CIRCUIT 3 HIGN VOLTAGE' AND A PART WAS REPLACED. HOWEVER, I PICKED UP THE VEHICLE ON 3/2 AND THE SERVICE INVOICE HAS A DATE OF 3/22. I HAVE NOT BEEN BACK TO THE DEALER SINCE 3/2. I HAD TO LEAVE THE VEHICLE AT THE DEALER ON 2/28 WHEN I SIGNED THE LEASE AGREEMENT BECAUSE THE DEALERSHIP TOLD ME THE TRANSMISSION WAS STILL LOCKED. WHEN I PICKED UP MY VEHICLE ON 3/2, I NOTICED THE VEHICLE HAD 34 ADDITIONAL MILES SINCE MY INITIAL INSPECTION ON 2/28. AFTER SEVERAL UNANSWERED EMAILS AND PHONE CALLS TO JERRY BRUMMET OVER THE LAST MONTH, HE FINALLY SENT ME THE SERVICE RECORDS TO SHOW THE REASON FOR THE ADDITIONAL MILEAGE. THIS SURPRISED ME BECAUSE I WAS NEVER NOTIFIED OF AN ISSUE WHEN I PICKED UP THE VEHICLE, NOR DID I RECEIVE ANY SERVICE RECORDS. I DO NOT FEEL SAFE DRIVING THIS VEHICLE AND WOULD HAVE TAKEN IT IN FOR SERVICE SOONER HAD THE DEALERSHIP NOTIFIED AND PROVIDED THE SERVICE RECORDS INDICATING THERE WERE FACTORY DEFECTS PRIOR TO MY RECEIVING IT. I PLAN TO TAKE THE VEHICLE TO ANOTHER DEALERSHIP FOR SERVICE IN THE MEANTIME. ULTIMATELY, I AM CONCERNED THIS IS A REPEAT SAFETY PROBLEM THAT MAY LEAD TO AN ACCIDENT OR OTHER BODILY INJURY.

HORN WILL NOT HONK UNLESS EXCESSIVE PRESSURE IS APPLIED. IT TAKES 2 HANDS TO HONK THE HORN. I HAVE NEVER SEEN A HORN THAT REQUIRED MORE THAN 1 FINGER TO HONK.

POWER LIFTGATE MALFUNCTION- LIFTGATE WAS OPERATED FROM THE REAR SWITCH. UPON ACTIVATION IT ROSE ALMOST FULLY AND THEN SLAMMED DOWN ON A PERSON WHILE THEY WERE ACCESSING THE REAR CARGO AREA, INJURING THEIR NOSE AND FACE. LIFTGATE FAILED TO STOP AT OBSTRUCTION. FROM THAT POINT ON LIFTGATE FAILED TO OPEN OR CLOSE WITHOUT MANUAL INTERVENTION. VEHICLE WAS STATIONARY, ENGINE RUNNING AND MOSTLY LEVEL STREET. WEATHER HAD BEEN RAINY BUT WAS NOT RAINING AT THE TIME, 63 DEGREE TEMP. NOT SURE IF IT WAS IN PARK OR DRIVE, BUT BRAKES WERE APPLIED AND OTHER PASSENGERS WERE ENTERING THE VEHICLE. THE NEXT MORNING THE POWER LIFTGATE HAS OPERATED NORMALLY.

THE PASSENGER WIPER BLADE DOES NOT COVER SUFFICIENT AREA OF THE WINDSHIELD TO PERMIT THE PASSENGER TO SEE THE 'RIGHT' PORTION OF THE ROAD. THE UNWIPED AREA ACCUMULATES DIRT AND ADDS TO THE VISUAL OBSTRUCTION OF FALLING RAIN. AN UNBELIEVABLE VISUAL DISTORTION OF THE ROAD RESULTS. I AM 70 AND AM APPALLED AT THE LACK OF WIPER COVERAGE IN A CRITICAL PORTION OF THE WINDSHIELD FOR THE PASSENGER. MOST PASSENGERS ASSIST THE DRIVER IN THE SAFE OPERATION OF THE VEHICLE BY CALLING ATTENTION TO IMPENDING PROBLEMS. THEIR CONTRIBUTION IS LIMITED IN THIS VEHICLE DUE TO THE POOR WIPER COVERAGE OF THE PASSENGER SIDE. THE PORTION OF THE CAR ABOVE THE BOTTOM OF THE WINDSHIELD WAS MOVED IN ON THE SIDES OF THE CAR BY DESIGN CHANGE. THE NORMAL SWATH OF THE PASSENGER WIPER FOR A FULL WIDTH CAR DOESL NOT WORK WITH THIS REDESIGN. THE PASSENGER WIPER PIVOT POINT SHOULD BE CLOSER TO THE FRONT OF THE PASSENGER AND WIPE TO THE RIGHT EDGE OF THE WINDSHIELD. HELP !!! THIS WIPER SITUATION IS REALLY AWFUL, UNNECESSARY, AND FATIGUING TO THE PASSENGER. THE A, B, AND C SECTIONS OF THE WINDSHIELD WERE SELECTED FOR THE SPECIFICATIONS WHEN WE HAD FULL WINDSHIELDS GOING TO THE RIGHT AND LEFT SIDES OF CAR. NOW THAT THE EDGES OF THE WINDSHIELD HAS BEEN MOVED IN, THE SPECIFICATION COVERAGE FOR THE PASSENGER IS NOT SUFFICIENT. THANKS FOR LISTENING AND HOPEFULLY, YOU CAN DO SOMETHING .... WE HATE DRIVING THIS CAR IN THE RAIN.

SLT-2 WITH HALOGEN PROJECTOR BEAM HEADLIGHTS. VERY VERY POOR HIGH & LOW BEAM PERFORMANCE. THE 6YR OLD EQUINOX I TRADED IN DID A BETTER JOB OF LIGHTING THE ROAD IN FRONT OF YOU. HAD THE DEALER CHECKED THEM OUT AND SAID THEY WERE OK. I HAD THEM ADJUST THE LOW BEAM DOWN TO PROVIDE BETTER ROAD VISIBILITY BUT FORWARD ILLUMINATION DISTANCE IS LESS. THE SALES & SERVICE DEPARTMENT SAID THERE IS NOTHING THEY CAN DO BUT I COULD LOOK INTO AFTER MARKET HEADLIGHTS. CONTACTED GM CUSTOMER SERVICE (CASE # 8-2826579557), THEIR DESIGN TEAM REVIEWED MY CONCERN AND THEY HAVE NO PLANNED CHANGES TO IMPROVE THEIR HEADLIGHTS. IF THESE LIGHTS PASS ANY FEDERAL LIGHTING REQUIREMENTS, THE TESTING MUST HAVE BEEN DONE IN A LAB AND NOT OUT IN THE REAL WORLD. GM DID A LOT OF THINGS RIGHT ON THIS NEW DESIGNED ACADIA BUT THE HEADLIGHTS IS NOT ONE OF THEM. NEXT STEP IS TO LOOK FOR AFTER MARKET LIGHTS.

STATIONARY, NEW VEHICLE POSSIBLY INAPPROPRIATELY EQUIPPED. A VEHICLE WITH A 2ND ROW BENCH SEAT PROVIDING SEATING FOR 3 WITH A CENTER OCCUPANT SEAT BELT BUT WITHOUT HEAD RESTRAINT (AND NO PROVISION FOR HEAD RESTRAINT). I CANNOT SEEM TO DETERMINE IF SUCH A CONFIGURATION DOES OR DOES NOT COMPLY WITH FEDERAL REGULATIONS. I CANNOT DETERMINE, THEREFORE, WHETHER I AM OR AM NOT LEGALLY ALLOWED TO CARRY A PASSENGER IN THE MIDDLE (INBOARD) SEAT.

LESS THAN 30 DAYS OF TAKING POSSESSION OF THE VEHICLE BRAND NEW, WE NOTED A WHINE WHEN YOU TURNED THE STEERING WHEEL. WE BROUGHT THE VEH IN TO DEALERSHP AND IT WAS REPORTED THE AIRBAG COIL WAS WRAPPED AROUND STEERING COLUMN CAUSING THE NOISE. THE COIL WAS REPLACED AND VEH RETURNED TO ME. WITHIN 24 HOURS THE NOISE RETURNED. THIS TIME THEY DETERMINED IT WAS THE FRONT LEFT STRUT AND REPLACED. A BRAND NEW VEHICLE SHOULD NOT NEED A NEW STRUT. DEALERSHIP SAID THEY HAD ANOTHER ACADIA IN FOR SAME PROBLEM

WHEN THE SUV GOES FROM 6 CYLINDERS TO 4 IT MAKES A VIBRATING NOISE LIKE A HELICOPTER OVER HEAD THEY SAY THIS IS NORMAL BUT IT IS EXTREMELY IRRITATING I FOUND OUT THAT OTHER PEOPLE HAVE COMPLAINED BUT IT APPEARS NOTHING IS BEING DONE THIS NOISE HAS TO BE FIXED

I BOUGHT A NEW 2017 GMC ACADIA DENALI THE END OF FEBRUARY AND THE NEXT DAY FOUND OUT THAT THE HORN DOES NOT WORK. THE HORN IS EXTREMELY HARD TO PUSH AND REQUIRES EXTRA PRESSURE WITH BOTH HANDS AND ARCHING MY BACK AGAINST THE SEAT TO TRY AND MAKE THE HORN TO WORK. I HAVE BEEN BACK TO THE DEALERS 3 TIMES IN 2 WEEKS AND IT IS NOT FIXED. THERE ARE ONLY 644 MILES ON THIS NEW SUV AND MY WIFE WILL NOT DRIVE IT BECAUSE IT IS A SAFETY CONCERN WITH NO HORN. *TR

THE HORN IS EXTREMELY HARD TO PUSH. MOST PEOPLE HAVE TO USE THE PALMS OF BOTH HANDS AND ARCH THEIR BACK AGAINST THE SEAT. I TOOK THE VEHICLE IN FOR SERVICE TO A GMC DEALER AND THEY WERE ALSO SHOCKED AT HOW DIFFICULT IT WAS TO PUSH THE HORN. AFTER FURTHER INVESTIGATION, GMC SAID THE HORN "WORKS AS CURRENTLY DESIGNED". THEY ALSO INDICATED THEY TRIED 3 OTHER 2017 ACADIA'S IN INVENTORY AND THEY WERE ALL VERY HARD TO PUSH. TO ME, THE PHRASE "WORKS AS CURRENTLY DESIGNED" IS INDICATIVE OF A PROBLEM. I AM UNABLE TO WARN PEDESTRIANS OR MOTORISTS OF AN IMPENDING DANGER. I HAVE TO WORK TOO HARD AND LONG TO PUSH THE HORN. A HORN SHOULD BE ABLE TO BE PUSHED VERY QUICKLY IN ORDER TO WARN OR ALERT OF A DANGER.
