Nissan North America is is expanding an earlier recall to include 45,000 2006 Sentra vehicles manufactured between 2 January, 2006, to 26 August, 2006, originally sold, or currently registered, in geographic locations associated with high absolute humidity - Puerto Rico, Hawaii, the US Virgin Islands, Guam, Saipan, American Samoa, Florida and adjacent counties in southern Georgia, as well as the coastal areas of Alabama, Louisiana, Mississippi and Texas.

Upon deployment of the passenger side frontal air bag, excessive internal pressure may cause the inflator to rupture with metal fragments striking and potentially seriously injuring the vehicle occupants.

Dealers will replace the passenger air bag inflator. Start date for the campaign will be advised later.
