On certain trucks, the wiring in the steering wheel clockspring could become disconnected. If this happens, the airbag could disconnect. This would cause the airbag warning lamp to turn on, and the driver-front airbag would not inflate in a crash. The problem may also cause the horn or other steering wheel-mounted controls not to work properly.
Safety Risk
An airbag that doesn't work properly could increase the risk of injury in a crash.
Corrective Actions
Ford will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, replace the clockspring.
