Summary: On certain passenger vehicles, the bolt attaching the horn assembly to the steering wheel hub may fail during a driver side front air bag deployment in extremely low ambient temperature.

Consequence: Should this occur, the horn assembly may come loose and could injure the driver.

Remedy: Dealers will replace the driver-side frontal air bag module with a new one free of charge. The recall is expected to begin during April 2006. Owners may contact Mazda at 800-222-5500.
