2016 GMC Acadia Brakes Problems

THE VEHICLE MAKES A CLUNK NOISE THAT COMES FROM THE BRAKES OR ABS. AFTER STARTING THE VEHICLE AND TAKING OFF I HEAR THE CLUNK AND FEEL IT ON THE BRAKE PEDAL. THIS HAPPENS EVERY DAY AND EVERY TIME YOU TAKE OF AFTER STARTING THE CAR. THE GM DEALER TOLD ME THEY KNOW THERE IS AN ISSUE/CONDITION THEY ARE AWARE OF BUT IT'S NOTHING TO WORRY ABOUT. THEY ISSUED A BULLETIN ON THIS CONDITION BUT I DON'T FEEL SAFE DRIVING A CAR THAT MAKES THAT NOISE EVERY TIME AFTER TAKING OFF IN THE ABS SYSTEM. THE CODE THEY GAVE ME IS PI1402A

I AM WRITING THIS LETTER TO INFORM YOU OF AN INCIDENT WHICH OCCURRED ON SUNDAY JUNE 4, 2017 WHILE DRIVING MY GMC ACADIA. I WORK IN REAL ESTATE SALES AND AFTER SHOWING HOME SITES TO A POTENTIAL BUYER I RETURNED TO MY MODEL PARKING LOT. I PULLED INTO THE PARKING LOT AND WAS IN THE PROCESS OF PARKING THE CAR WHEN THE CAR SUDDENLY BEGAN REVVING. I WAS ONLY A FEW FEET AWAY FROM THE PARKING BLOCK AND I HAD MY FOOT ON THE BRAKE. I TRIED TO PUT THE CAR IN PARK BUT IT WOULD NOT MOVE. THE CAR KEPT REVVING AND JERKED FORWARD WITH SO MUCH FORCE THAT I WENT OVER THE PARKING BLOCK, THROUGH THE BUSHES AND THROUGH THE PVC FENCE. I HAD MY FOOT ON THE BRAKE THE ENTIRE TIME AND KEPT TRYING TO PUT THE CAR IN PARK. AFTER A FEW FEET BEYOND THE FENCE THE CAR FINALLY WENT INTO PARK AND I WAS ABLE TO STOP THE CAR. I AM COMPLETELY GRATEFUL THAT NO PEDESTRIANS WERE ON THE OTHER SIDE OF THE FENCE. AS I AM SURE YOU CAN IMAGINE I WAS TERRIFIED TO GET BACK INTO THE CAR. I CALLED MY HUSBAND AND HAD HIM BRING ME THE OTHER CAR SO I CAN FINISH OUT MY WORK DAY. THE ACADIA IS OUR FAMILY CAR AND THE CAR THAT TRANSPORTS OUR FOUR CHILDREN. MY HUSBAND TOOK THE CAR INTO FERMAN DEALERSHIP, THE DEALERSHIP WHICH WE LEASED THE CAR FROM, AND THEY BLEW HIM OFF SAYING THAT I PROBABLY GOT CONFUSED BETWEEN THE BRAKE AND THE THROTTLE. I AM 41 YEARS OLD AND HAVE BEEN DRIVING SINCE I WAS 16 AND I CAN ASSURE YOU THAT I DID NOT GET CONFUSED AND I FIND IT COMPLETELY INSULTING THAT THEY EVEN SAID THAT. IT DOES NOT SEEM THAT WE HAVE ANY LEGAL RECOURSE FOR BEING ABLE TO TERMINATE OUR LEASE DUE TO THIS, WHICH IS WHAT WE WOULD WANT. I WANT THIS INCIDENT REPORTED IN WRITING SHOULD GOD FORBID IT HAPPENS AGAIN AND THERE IS MORE DAMAGE THAN JUST TWO FENCE PANELS.

TL* THE CONTACT OWNS A 2016 GMC ACADIA. THE CONTACT STATED THAT THE BRAKES WERE NOT CONSISTENT AND MADE IT DIFFICULT TO STOP THE VEHICLE. WHILE AT A RED LIGHT, THE BRAKES FAILED WITHOUT WARNING. THE VEHICLE WAS TOWED TO A LOCAL DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE FAILURE RECURRED AND THE VEHICLE WAS TOWED TO ANOTHER DEALER WHO WAS UNABLE TO DUPLICATE THE FAILURE. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND INFORMED THE DEALER TO SEND THE VEHICLE HOME, IF THE FAILURE WAS NOT DUPLICATED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 1,036.
