This is an expansion of an existing recall.
"The affected vehicles are equipped with a dual-stage driver frontal airbag that may be susceptible to moisture intrusion which, over time, could cause the inflator to rupture," said NHTSA in its recall summary. "In the event of a crash necessitating deployment of the driver's frontal airbag, the inflator could rupture, with metal fragments striking the driver or other occupants, resulting in serious injury or death."
Fiat-Chrysler spokesman Eric Mayne told Edmunds on Saturday the recall expansion was "not triggered by a bad deployment," but by an internal review of vehicles affected by the Takata recall.
The affected Challengers were built from September 19, 2007 to October 29, 2010.
Dodge dealers will replace the driver's frontal airbag inflator. Fiat-Chrysler said parts to fix the vehicles are not currently available.
Interim notices will be mailed to owners starting August 14. A second notice will be sent once remedy parts become available. Owners can contact Chrysler customer service at 1-800-853-1403.
Edmunds says: Owners of these cars should stay in close touch with their dealers for further information.
