2017 GMC Acadia

WHILE DRIVING, THE HORN FAILED TO ACTIVATE WHEN DEPRESSED. SUBSEQUENTLY, WHEN PARKED, THE HORN REQUIRED EXCESSIVE PRESSURE TO ACTIVATE (TWO HANDS). TOOK THE VEHICLE TO THE DEALER, THE SERVICE ADVISOR TRIED THE HORN AND AGREED THAT IT REQUIRED EXCESSIVE FORCE TO BLOW THE HORN. P/N 84050792 WAS REPLACED WITH NO CHANGE IN THE PRESSURE REQUIRED TO BLOW THE HORN. RESEARCH SHOWS MULTIPLE COMPLAINTS REGARDING THE SAME ISSUE.

THE RADIO IS DANGEROUSLY BRIGHT WHEN DRIVING AT NIGHT. THE BRIGHTNESS IS AFFECTED BY THE BACKUP CAMERA; ONCE THE BACKUP CAMERA IS ACTIVATED THE RADIO BRIGHTNESS IS INCREASED AND WILL NOT DIM UNTIL YOU SHUT THE CAR OFF. THERE IS NO EASY WAY TO SHUT THE DISPLAY OFF WITHOUT NAVIGATING THROUGH THE TOUCHSCREEN MENUS, AND IF YOU ADJUST ANYTHING WITH THE RADIO OR HVAC THE DISPLAY COMES BACK ON AT FULL BRIGHTNESS. VEHICLE HAS BEEN TO THE DEALER MULTIPLE TIMES, WITH GM ENGINEER VISITING TO SEE THE ISSUE. THERE ARE SOME ACADIAS WITH THE SAME RADIO THAT ISN'T AFFECTED BY THIS PROBLEM. WAS TOLD BY THE ENGINEER THAT THERE IS NOTHING THAT CAN BE DONE AND I HAVE TO JUST GET USED TO THE EXTRA BRIGHTNESS. THIS "EXTRA BRIGHTNESS" IS TOO DANGEROUS FOR ME TO DRIVE AT NIGHT, AS IT IMPAIRS MY VISION. I AM NOW STUCK WITH A $32000 VEHICLE THAT I CANNOT SAFELY DRIVE AT NIGHT.

NEW 2017 GMC ACADIA DENALI FWD. LESS THAN 100 MILES. HORN DOES NOT OPERATE WITH NORMAL DRIVER PRESSURE UNDER ANY CONDITIONS. REQUIRES EXCESSIVE PRESSURE TO OPERATE, REQUIRING USING BOTH HANDS AND THEN ONLY IN ONE SPOT. GM IS AWARE OF THE PROBLEM AND HAS DONE NOTHING TO CORRECT, CALLING IT IS OPERATING "AS DESIGNED". THE DESIGN IS FLAWED AND GM FAILS TO ADMIT IT AND TAKE CORRECTIVE ACTION. IT IS PAST TIME THAT THIS PROBLEM IS FIXED, AS IT HAS BEEN REPORTED MANY TIMES BY OTHER GMC ACADIA OWNERS AND IS ON RECORD WITH THE NHTSA. DOES SOMEONE HAVE TO BE KILLED BEFORE A FIX IS RELEASED? DOES SOMEONE HAVE TO BE KILLED BEFORE THE NHTSA ACTS ON THIS POTENTIALLY LETHAL DEFECT?

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.

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.

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.
