WHILE DRIVING TO WORK , VEHICLE IN FRONT OF ME STOPPED ABRUPTLY , I STEPPED HARD ON THE BRAKE PEDAL I WAS GOING APPROX. 30 MPH, THE BRAKE PEDAL PULSATED ( ABS ACTIVATING) FOR A SECOND OR 2 AND STOPPED ,AND THE BRAKE PEDAL SUDDENLY SANK TO THE FLOOR,THE VEHICLE KEPT GOING, I PULLED THE EMERGENCY BRAKE TO TRY TO STOP , BUT IT WAS TOO LATE I RAN INTO THE VEHICLE IN FRONT OF ME CAUSING CONSIDERABLE DAMAGE TO BOTH VEHICLES. I CONTACTED HYUNDAI DEALER AND WAS TOLD IT IS NOT A DEFECT AND ALSO IS NOT UNDER WARRANTY. I NOW HAVE TO HAVE THE CAR FIXED AT MY OWN EXPENSE. I FEEL A RECALL BY HYUNDAI SHOULD BE INITIATED SINCE THIS SEEMS TO BE COMMON DEFECT, PLEASE HELP! *TR
