THE RIGHT SIDE CAMERA TURNED OFF AND REMOVED VISIBILITY FROM THAT SIDE OF THE VEHICLE THROUGH THE INFOTAINMENT SCREEN.

TRUCK ALSO GAVE DTC P25A2. I CAN'T STRESS ENOUGH THAT IT WASN'T JUST DEGRADED BRAKING, IT WAS ALMOST NOTHING AT ALL. IT TOOK NEARLY 1/8TH OF A MILE TO GET IT STOPPED ON A MILD DOWNHILL GRADE. | Crash: No Fire: No | 4,947 |

| Feb 2020 | STEERING,ELECTRICAL SYSTEM,SERVICE BRAKES | 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.

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 IS THE 5TH TIME THIS HAS HAPPENED TO MY TRUCK. | Crash: No Fire: No | 10,884 |
