The problem
VEHICLE DESCRIPTION: LIGHT DUTY PICKUP TRUCKS AND MULTI-PURPOSE PASSENGER VEHICLES. ONE OR BOTH FRONT BRAKE ROTOR/HUBS WERE BUILT WITH AN OUT-OF-SPECIFICATION GRAY IRON THAT CAN FAIL DURING THE LIFE OF THE VEHICLE.
Risk
IF A DRIVER CONTINUES TO DRIVE WITH A CRACKED ROTOR, THE CRACKS COULD CONTINUE AROUND THE WHEEL MOUNTING BOLT CIRCLE AND ULTIMATELY RESULT IN A WHEEL SEPARATION.
What owners should do
DEALERS WILL INSPECT THE ROTORS FOR A CORE DATE OF "287" AND, IF FOUND, REPLACE THE ROTOR.
