I WAS BRAKING APPROACHING A LIGHT ON A STATE ROAD, WHEN THE BRAKE WENT ALL THE WAY TO THE FLOOR SUDDENLY AND IT FELT AS THOUGH THE WHEELS LOCKED UP. THE VEHICLE SLOWED BUT DID NOT STOP, I REAR ENDED A VEHICLE IN FRONT OF ME.

BRAKE ISSUE: I HAD AN ACCIDENT DUE TO A BRAKE FAILURE ON THIS CAR. I WAS DRIVING VERY SLOWLY GOING DOWNHILL (SPEEDS 0 TO 10 MPH) IN A LINE OF CARS STOPPING AND GOING, STOPPING AND GOING MANY TIMES. AT FIRST THE BRAKE PEDAL FELT NORMAL AS PRESSURE WAS APPLIED THE CAR SLOWED THEN PETAL RESISTANCE WOULD DROP AND THE CAR WOULD SPEED UP DUE TO THE DOWNHILL GRADE. I APPLIED FOOT PRESSURE TO PETAL AGAIN AND THE SAME THING HAPPENED OVER AND OVER AGAIN. I SLOWLY RAN INTO THE BACK OF THE CAR IN FRONT OF ME. I HIT THE CAR IN FRONT OF ME MANY TIMES AS IT MOVED FORWARD. THIS CAR HAS AN AUTONOMOUS EMERGENCY BRAKING (AEB) EQUIPPED ON IT. THE AEB IS SUPPOSED TO APPLY BRAKES WHEN YOU'RE ABOUT TO HIT SOMETHING. IT'S SUPPOSED TO TURN OFF AT ABOUT 6 MPH, IN THIS TRAFFIC MY SPEED VARY THROUGH THIS POINT MANY TIMES. I FEEL THE CONSTANT ON AND OFF OF AEB CONFUSED THE CONTROL SYSTEM ON THE CAR AND CAUSE THE BRAKES TO MALFUNCTION. THE ROAD CONDITION WAS WET BUT NO STANDING WATER. THE ACCIDENT WAS NOT A SKID. THE TIRES ARE IN GREAT SHAPE THE CAR ONLY HAS 14000 MILES ON IT.
