NHTSA recall 15V322000

What's wrong: The affected vehicles are equipped with a passenger side frontal air bag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture.

Why it matters: In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.

The fix: Ford will notify owners, and dealers will replace the front passenger air bag inflator, free of charge. The recall began on December 4, 2015.
