Open the full vehicle complaint log (all categories)THIS BRAND NEW CAR I BOUGHT HAS THE OPTIONS OF "ADVANCED SAFETY SYSTEM" WHICH WAS SUPPOSED TO PREVENT A COLLISION. I WAS DRIVING ON ADAPTIVE CRUISE CONTROL, 4 CAR DISTANCE ON HIGHWAY. AS I WAS DRIVING CLOSE TO THE EXIT WHERE I NEEDED TO TAKE, ADAPTIVE CRUISE CONTROL DID NOT SEEM TO BE WORKING SINCE I NOTICED THAT THE CAR WAS NOT SLOWING DOWN AS I WAS APPROACHING THE CAR IN FRONT OF ME. I PRESSED ON THE BRAKE TO SLOW DOWN MY VEHICLE, BUT THE VEHICLE DID NOT RESPOND TO MY BRAKING. I PRESSED DOWN BRAKE AS HARD AS POSSIBLE TO STOP THE VEHICLE, BUT MY VEHICLE CONTINUED TO MOVE WITHOUT STOPPING UNTIL IT (FIRST CAR) HIT THE CAR IN FRONT OF IT AND THE CAR IN FRONT OF THE SECOND CAR HIT THE THIRD CAR. AUTOMATIC EMERGENCY BRAKING SHOULD HAVE KICKED IN TO PREVENT COLLISION, BUT IT DID NOT. THIS CAR WAS SUPPOSED TO GIVE ME FORWARD-COLLISION WARNING SIGN AS IT WAS APPROACHING THE CAR IN THE FRONT, BUT IT NEVER DID. SENSOR MIGHT HAVE NOT BEEN WORKING AT THE TIME OF INCIDENT.
