NHTSA Complaint #11298496 — 2019 GMC SIERRA 1500

PURCHASED NEW, DEC 24, 2019. CURRENT ODOMETER 645MILES. THE VEHICLE WAS PARKED FOR ABOUT 15 MINUTES, WHEN I RETURNED TO MY TRUCK AND TURNED IT ON, MULTIPLE WARNING TONES BEGAN TO SOUND AND THE DASHBOARD WAS ILLUMINATED WITH MULTIPLE WARNING LIGHTS (ABS, TRACTION CONTROL, CHECK ENGINE, PARKING BRAKE) AND MESSAGES READING: "BRAKE SYSTEM FAILURE 62MPH TOP SPEED," 'SERVICE TRAILER BRAKE SYSTEM,' 'STEERING ASSIST IS REDUCED DRIVE WITH CARE,' 'SERVICE ESC.' I TURNED THE VEHICLE OFF AND ON MULTIPLE TIMES OVER THE COURSE OF 20 MINUTES, EXITING THE VEHICLE, LOCKING THE DOORS, UNLOCKING THE DOORS, AND STARTING THE PROCESS FROM THE BEGINNING. I DECIDED I WOULDN'T BE DRIVING OVER 62MPH AS I WAS ONLY 2 MILES FROM MY HOME, SO I DECIDED TO BACK OUT AND DRIVE HOME WITH FULL INTENTIONS OF CALLING THE DEALERSHIP IN THE MORNING. WHEN I TRIED TO BACK OUT I REALIZED THAT I HAD ALMOST ZERO BRAKING POWER, HAVING TO ALMOST STAND UP ON THE BRAKE PEDAL TO STOP THE VEHICLE WITHOUT GIVING IT ANY GAS, AND TURNING WAS DIFFICULT (SIMILAR TO MANUAL STEERING IN A VINTAGE VEHICLE). I KNEW DRIVING HOME WOULD NOT BE SAFE. I TURNS THE VEHICLE OFF AND ON ONCE MORE AND ALL THE WARNING MESSAGES AND LIGHTS WERE NO LONGER THERE. THE CHECK ENGINE LIGHT REMAINED ON AND IS STILL ON. I WAS ABLE TO DRIVE HOME AS THOUGH NOTHING HAPPENED, BUT AM FEARFUL THIS WILL HAPPEN WHILE DRIVING DOWN THE ROAD, ESPECIALLY WHILE MY CHILDREN ARE IN THE CAR. I HAVE READ MULTIPLE FORUMS, THIS IS NOT AN ISOLATED INCIDENT, WITH MANY OTHERS EXPERIENCING THE SAME EXACT ISSUE, SOMETIMES WHILE ACTUALLY DRIVING, IN 2019 GMC SIERRAS AND CHEVY SILVERADO'S. THIS IS ABSOLUTELY UNACCEPTABLE AND WILL RESULT IN INJURIES AND DEATHS IF GM DOES NOT RESOLVE THE ISSUE.
