NHTSA Complaint #11308470 — 2019 GMC SIERRA 1500

MY PICKUP STARTED, I PULLED OUT ON ROAD AND SPED UP TO 35 MPH, WHEN I STEPPED ON BRAKES TO SLOW DOWN THEY WERE UNRESPONSIVE, SO I BEGAN PUMPING. THEY FELT VERY HARD TO PUMP AND WERE NOT SLOWING THE TRUCK DOWN. LIGHTS CAME ON SAYING SERVICE BRAKES ETC. AS I COASTED TO TRY TO SLOW DOWN OFF SIDE OF ROAD. I HAD TO KEEP PUMPING THE BRAKES DOWN TO FLOORBOARD AND I?M NOT SURE THEY WERE EVEN WORKING. I LOST POWER STEERING AND WAS ALMOST INVOLVED IN A SERIOUS REAR-END COLLISION. 4 MESSAGES APPEARED ON DIGITAL DASH WHILE DRIVING. SERVICE ESC, BRAKE SYSTEM FAILURE 62 MPH TOP SPEED, SERVICE TRAILER BRAKE SYSTEM, STEERING ASSIST REDUCED. I HAD TO PRESS BRAKE PEDAL TO THE FLOOR WITH EXTREMELY EXCESSIVE FORCE TO GET TRUCK TO STOP. THIS FAILURE COULD HAVE EASILY RESULTED IN VEHICLE ACCIDENT, OR EVEN A FATALITY ACCIDENT. I DOUBT I WILL EVER CARRY MY FAMILY IN THE TRUCK AGAIN DUE TO THIS AND I CERTAINLY WILL NOT ALLOW MY CHILDREN TO DRIVE THE TRUCK. THIS IS THE 5TH TIME THIS HAS HAPPENED TO MY TRUCK.
