NHTSA Complaint #11325454 — 2017 GMC SIERRA 1500

OUR TRUCK IS LESS THAN THREE YEARS OLD WITH APPROXIMATELY 69000 MILES. THE TRANSMISSION JUST STARTED SLIPPING OUT OF THE BLUE WHILE DRIVING THRU A NEIGHBORHOOD. WHILE IN DRIVE IT WOULD MOVE BUT ONCE ACCELERATING IT WOULD REV UP AND NOT CHANGE GEARS. THIS HAPPENED WITHOUT WARNING, WITHOUT AN ENGINE OR WARNING LIGHT. WE DO ALL THE NECESSARY REGULAR MAINTENANCE. IN ADDITION TWO YEARS AGO WHILE THE TRUCK WAS A YEAR OLD, THE BRAKES WENT OUT WHILE DRIVING ON THE INTERSTATE. I GUESS IT WAS THE BRAKE VACUUM PUMP OR WHATEVER THAT DIDN'T ALLOW THE BRAKE PEDDLE TO BE PRESSED WHICH PROVIDED ME WITH NO BRAKES. AGAIN WITH ABSOLUTELY NO WARNING! THIS LATER BECAME RECALL ISSUE BUT NOT BEFORE IT HAD ALREADY HAPPENED TO ME! I UNDERSTAND THERE IS A CLASS ACTION LAW SUIT AGAINST GMC FOR TRANSMISSION PROBLEMS AND I WOULD CONSIDER BEING A PART OF THIS. THIS IS A 50;000$ AND RELATIVELY NEW TRUCK, THIS IS UNACCEPTABLE! THE DEALER NOW WANTS OVER 4000$ FOR REPAIRS. *TR
