Sep 16, 1996

THE RAIL OF THE AUTOMATIC SHOULDER BELT CAN WEAR SUFFICIENTLY SUCH THAT THE CABLE WHICH RETRACTS THE BUCKLE ASSEMBLY WILL BECOME JAMMED IN THE RAIL RENDERING THE SHOULDER BELT INOPERATIVE.

Consequence & remedy

Consequence: IN THE EVENT OF A VEHICLE COLLISION, THE OCCUPANT WOULD NOT BE ADEQUATELY RESTRAINED INCREASING THE RISK OF PERSONAL INJURY.

Remedy: DEALERS WILL REPLACE INOPERATIVE SHOULDER BELTS. MAZDA HAS EXTENDED THE WARRANTY COVERAGE ON THE DRIVER AND PASSENGER AUTOMATIC SHOULDER BELT RAIL AND MOTOR FOR THE LIFE OF THE VEHICLE.
