The number of recalled air bag inflators and impacted vehicles and manufacturers, in combination with the supply issues related to these air bag recalls, presents an unprecedented level of complexity to the recall and remedy process. As of the date of this Federal Register Notice, these recalls of defective Takata air bag inflators constitute the largest Safety Act recall in NHTSA's history, and one of the largest consumer product recalls in United States history, with approximately 34 million air bag inflators currently requiring replacement. The risk of harm presented by the defective Takata air bag inflators transcends the scope of the usual Safety Act recall. Accordingly, NHTSA is hereby opening a coordinated remedy program proceeding.
