ON JUNE 24, 2016, BETWEEN 1:30 PM AND 2 PM, I WAS DRIVING FROM BRENTWOOD CA TO VALLEJO CA ON HWY 780 W AND AFTER TURNING A CURVE ON THE FREEWAY WHICH SLOPED DOWN TOWARDS CURTOLA PARKWAY, I APPLIED THE BRAKES AT ABOUT 30 MILES PER HOUR AFTER I EMERGED FROM THE OVERPASS WHICH WAS AT LEAST 5 CAR LENGTHS BEFORE THE CARS AHEAD OF ME WHICH WAS STOPPED AT A RED TRAFFIC LIGHT. HOWEVER, THE JEEP CONTINUED TO ROLL EVEN THOUGH I PRESSED ON THE BRAKES TO THE FLOOR BOARD. WHEN I REALIZED THE JEEP DID NOT STOP, AFTER CHECKING FOR VEHICLES ON THE LEFT FROM THE REAR VIEW MIRROR, I SWERVED TO THE LEFT TO AVOID HITTING THE TRUCK IN FRONT OF ME, BUT I STILL HIT THE LEFT CORNER OF THE NISSAN TRUCK IN FRONT OF ME BUT THE TRUCK DID NOT HIT THE VEHICLE IN FRONT OF HIM. I DAMAGED THE RIGHT CORNER OF THE FRONT OF MY JEEP. THE JEEP IS UNSAFE BECAUSE THE BRAKES FAILED AND WOULD HAVE CAUSED A FATAL ACCIDENT TO ME, MY THREE PASSENGERS, AND OTHER VEHICLES HAD I BEEN TRAVELLING AT A HIGH SPEED. I COMPLIED WITH ALL AVAILABLE RECALL REPAIRS INCLUDING THE BRAKE RECALL IN 2014 AND ALL THE SUGGESTED CHRYSLER MAINTENANCE ON THE JEEP. I REPORTED THE ACCIDENT TO MY INSURANCE GEICO AND TO CHRYSLER.
