2017 GMC ACADIA Complaints

2017 GMC ACADIA DENALI. CONSUMER WRITES IN REGARDS TO MECHANICAL ISSUES. *LD THE CONSUMER STATED THE VEHICLE WAS RUNNING VERY LOUD AND ROUGH UPON INITIAL START UP. THE CHECK ENGINE AND SERVICE ELECTRIC PARKING BRAKE LIGHT ILLUMINATED. SERVICE PARKING BRAKE APPEARED ON THE DIC, A MESSAGE STATING AWD OFF APPEARED IN THE DIC. AND A NOTIFICATION FOR AN ISSUE WITH THE EMISSIONS SYSTEM ALSO APPEARED. *JS

HEADLIGHTS ARE DIM TO THE POINT OF BEING DANGEROUS. DEALER CONFIRMS THAT ALL 2017 ACADIA ARE LIKE THIS. THIS IS BY NO MEANS THE FIRST COMPLAINT ABOUT THIS ISSUE. AN ACCIDENT WAITING TO HAPPEN.

THE ADAPTIVE CRUISE CONTROL (ACC) IN MY 2017 ACADIA DENALI WILL SHUT OFF AND EVEN CAUSE THE VEHICLE TO BREAK FOR NO REASON. THIS HAS HAPPENED NUMEROUS TIMES, EVEN WITH NO OTHER VEHICLE ON THE ROAD OR OBSTACLES IN THE ROAD. WHEN IT HAPPENS THE ACC WILL SHUT OFF, YOU WILL HEAR TWO DISTINCT CHIMES AND YOU WILL SEE A MESSAGE SAYING, 'ADAPTIVE CRUISE CONTROL DISENGAGED'. AFTER THIS HAPPENS YOU WILL NOT BE ABLE TO REENGAGE THE ACC AND IF YOU TRY THE VEHICLE WILL DISPLAY A MESSAGE THAT SAYS 'TEMPORARILY UNAVAILABLE.' I HAVE HAD IT TO THE DEALERSHIP NUMEROUS TIMES AND THEY HAVE STATED THEY DON'T KNOW WHY IT WOULD HAPPEN, AND CANNOT DO ANYTHING UNLESS THEY CAN DUPLICATE IT. IT HAPPENS A LOT BUT THE DEALERSHIP AND GMC SAY THERE IS NO PROBLEM. THE FIRST TIME THIS HAPPENED IT ALMOST CAUSED MY WIFE TO WRECK, SINCE THE ACC SHUT OFF AND APPLIED BRAKES WITH NO OTHER CAR ON THE ROAD, BADLY STARTLING HER, AND SHE THOUGHT SHE HAD HIT SOMETHING. I EVEN HAVE A VIDEO OF THE ACC SHOWING 'TEMPORARILY UNAVAILABLE' AFTER ONE OCCASION IT SHUT OFF AND SLOWED THE VEHICLE. IN THIS INSTANCE THERE WERE NO CAR IN FRONT OF ME OR ON EITHER SIDE, BUT THERE WAS ONE BEHIND ME WHO I AM SURE WAS NOT HAPPY WHEN THE VEHICLE IN FRONT OF HIM BRAKED FOR NO REASON. A GMC REPRESENTATIVE TOLD ME I CAN HAVE ALL THE VIDEO I WANT, BUT IT 'DOESN'T MATTER AND WON'T CHANGE ANYTHING'. THE DEALERSHIP DID DO A COMPLETE DIAGNOSTIC ON ONE OCCASION AND FOUND EVIDENCE THAT THE ACC HAD SHUT OFF, BUT THE CODE DID NOT SAY WHY IT SHUT OFF. THIS HAS HAPPENED AT DIFFERENT SPEEDS RANGE FROM 55 TO 75 MPH. WE HAVE HAD IT HAPPEN THREE TIMES IN A 30 MINUTE PERIOD AND DROVE FOR A MONTH WITHOUT IT HAPPENING. THIS CAUSES AN UNSAFE DRIVING EXPERIENCE AND SHOULD BE FIXED OR THE VEHICLE REPLACED. I HAVE FOUND OTHER PEOPLE ONLINE WHO HAVE EXPERIENCED THIS, BUT THERE ARE NOT ENOUGH OF US TO WARRANT GMC DOING ANYTHING.

AFTER RELEASING ELECTRONIC PARKING BRAKE, THE SERVICE PARKING BRAKE LIGHT COMES ON AND THE PARKING BRAKE LIGHT FLASHES. PARKING BRAKE IS NO LONGER OPERATIONAL.

HIGH HORN EFFORT - HORN DOES NOT ACTIVATE WHEN PRESSED ON. DRIVER HAS BEEN UNABLE TO NOTIFY OTHER CARS COMING INTO THEIR LANE. CONCERNED THAT THEY WILL BE UNABLE TO AVOID AN ACCIDENT. TOOK DELIVERY OF VEHICLE ON 01SEP2017 WITH THIS AS A KNOWN ISSUE. HAVE NOT HAD ANY RESOLUTION UNTIL VEHICLE WENT INTO SERVICE AROUND 09JAN18. BULLETIN ISSUED TO REPLACE WIRE HARNESS. THIS NEW WIRE HARNESS DID NOT IMPROVE THE CONDITION AT ALL - MAY EVEN BE WORSE THAN BEFORE. THIS IS A SAFETY ISSUE - GM NEEDS TO ADDRESS THIS IMMEDIATELY. THIS IS EITHER DUE TO THE DRIVER AIRBAG CUSHION PACK HEIGHT OR WIRE HARNESS LIMITING HORN TRAVEL.

AS MUCH AS I LOVE THE VEHICLE AS A WHOLE, IT UNFORTUNATELY HAS THE WORST HEADLIGHTS I HAVE EXPERIENCED IN ANY VEHICLE THAT I HAVE EVER DRIVEN. AS SOMEONE WHO HAS PERFECT VISION, I OFTEN FIND MYSELF SQUINTING TO SEE THE ROAD AHEAD OF ME AND VARIOUS SIGNS. IT HAS GOTTEN TO THE POINT WHERE I HAVE RESORTED TO DRIVING WITH MY HIGH BEAMS ON, JUST SO I CAN SEE WHERE I'M GOING IN CITY STREETS, HIGHWAY DRIVING, AND MAKING TURNS. I'VE NEVER HAD THIS ISSUE WITH ANY OTHER VEHICLE THAT I HAVE DRIVEN AND THE UNFORTUNATE THING IS THAT MY FATHER HAS NEARLY THE SAME IDENTICAL VEHICLE AS ME AND IS EQUALLY DISSATISFIED WITH THE HEADLIGHTS. I WOULD CONSIDER THESE AS DANGEROUS AS ANYTHING TO DRIVER, PEDESTRIAN, AND PROPERTY RELATED SAFETY. I WOULD STRONGLY URGE THAT IF GM DOES NOT STEP UP AND CORRECT THIS DANGEROUS OBSTACLE TO MY LIFE, THEN I WOULD STRONGLY URGE AN INVESTIGATION AND AN IMMEDIATE RECALL OF THIS VEHICLE BY THIS ORGANIZATION.

THE HEADLIGHT HIGH BEAM LIGHT PATTERN IS A VERY DIM AND NARROW FOCUSED BEAM AND DOES NOT ALLOW ENOUGH SIDE TO SIDE ILLUMINATION. THE LEFT AND RIGHT SIDE LIGHTING IS VIRTUALLY NON-EXISTENT ON WET ROADS WHEN THE HIGH BEAMS ARE ON. THE HIGH BEAMS ALSO CONVERGE TO A SMALL NARROW SPOT ON THE ROADWAY. THE LACK OF EFFECTIVE LEFT AND RIGHT SIDE ROAD LIGHTING IS A SAFETY ISSUE AS IT IS EXTREMELY DIFFICULT TO SEE PEOPLE OR OBJECTS.ON THE SIDE OF THE ROAD. ALSO, THE LOW BEAMS LACK SUFFICIENT.BRIGHTNESS ALTHOUGH THE LEFT AND RIGHT SIDE LIGHT PATTERN IS SUFFICIENT. ALTHOUGH MY COMPLAINT WAS ESCALATED TO A GMC SENIOR ADVISOR, NO ACTION WAS TAKEN BY GMC. THE ADVISOR STATED, "WORKS AS DESIGNED". NO ALTERNATIVE BULB OR AFTER MARKET LIGHTING WAS RECOMMENDED BY GMC AS I WAS TOLD THIS WOULD VOID THE WARRANTY. THE SAFETY CONCERNS MY FAMILY AND I FEEL ABOUT THE VEHICLES HEADLIGHTS WERE DISMISSED BY THE COMPANY.

THE VEHICLE SHIFTS VERY HARSHLY BETWEEN SECOND AND THIRD GEARS WHEN ACCELERATING. SOMETIMES IT IS SO HARSH THAT IT SLAMS YOU BACK IN THE SEAT. THE DEALER SAYS THAT IT IS "NORMAL". IT BEGAN AFTER OWNING THE VEHICLE FOR ONE FULL YEAR.

2 INSTANCES WITHIN A 2 WEEK PERIOD. ON 12/13/2017 VEHICLE IS BEING DRIVEN AND ENGINE POWER IS LOST AND CAR TURNS OFF WE HAD TO PULL OVER SIDE OF THE ROAD WHEN TRYING TO RESTART THE CAR IT SPUTTERS AND WONT START.. 2ND INSTANCE ON 12/24/2017 CAR WAS ONCE CAR WAS PUT IN GEAR IT STALLED WOULD NOT RESTART OR EVEN TURN OVER. DEALER REPLACED BATTERY AND FUEL PUMP REGULATOR MODULE THE 1ST TIME. 2ND TIME DEALER DOES NOT KNOW WHAT THE PROBLEM IS.

I WAS DRIVING FOR APPROXIMATELY 20 MILES ON A HIGHWAY WITH MY WINDSHIELD WIPERS IN THE INTERMITTENT POSTION. THERE WAS A LIGHT SNOW COMING DOWN. THE WIPERS WORKED UP TO THIS TIME. THE DRIVER SIDE WINDSHIELD WIPER STOPPED WORKING. THIS AFFECTED VIABILITY DRAMATICALLY. IT WOULD HAVE BEEN WORSE WITH HEAVIER SNOW. I TOOK IT TO THE DEALER AND THEY FOUND THE SCREW HAD LOOSENED AND THE WIPER MOTOR AND WINDSHIELD WIPER WERE DISCONNECTED.
