2004 Subaru Impreza RecallsFront Passenger Air Bag Defect
In a crash that deploys the passenger front air bag, the inflator of the air bag can rupture, causing metal debris to strike vehicle occupants. Dealers will replace the front passenger air bag inflator free of charge to correct the concern.
Moisture sensitive airbag system components may deteriorate in humid climate regions, causing an increase in inflator pressure which ruptures when passenger airbags are deployed. Injury can result from inflator parts striking an occupant. Dealers will replace affected airbag inflators to correct this concern. Subaru is the manufacturer of Saabs affected by this recall. This recall supersedes Subaru recall 14V-471.
This limited regional recall is for vehicles currently registered or first sold in Florida, Puerto Rico, Hawaii and the U.S. Virgin Islands, and equipped with Takata-brand air bag inflators. Upon deployment the driver and/or passenger airbag inflator could rupture, increasing the risk of personal injury. Subaru dealers will replace the affected airbag inflator modules to correct this concern.
