NHTSA Complaint #10616647 — 2014 GMC ACADIA

WHEN ACCELERATING BETWEEN 10 AND 20 MILES PER HOUR, SOMETHING UNDERNEATH THE BODY OF THE CAR, MOVES IN A CIRCULAR MOTION AND CLUNKS UNDERNEATH THE GAS PEDAL. THIS MOVEMENT CAN BE FELT UNDER THE GAS PEDAL AND FLOOR AS WELL AS HEARD. THIS OCCURS 80-90 PERCENT OF THE TIME AFTER STARTING THE VEHICLE. THE VEHICLE ALSO SHIFTS HARD INTO GEAR AT ABOUT THIS MPH. THE DEALERSHIP HAS TESTED SEVERAL ACADIAS AND FOUND A GM BULLETIN ON THIS EVENT. THE GM BULLETIN INDICATES THIS IS A "NORMAL" CYCLING OF THE ABS BRAKE SYSTEM THAT OCCURS ON THE ACADIA AND CHEVY TRAVERSE MODELS. SO FAR GM HAS BEEN UNWILLING TO RESOLVE THIS ISSUE, YET BECAUSE IT IS A BRAKE ISSUE AND IS FELT UNDER THE GAS PEDAL, THE SAFETY OF THIS VEHICLE IS HIGHLY CONCERNING TO ME. I DRIVE A VARIETY OF VEHICLES FOR WORK AND DO NOT EXPERIENCE THIS ROTATION AND CLUNK WITH ANY OTHER VEHICLE. I AM CONCERNED ABOUT MY SAFETY. *JS
