Data Attribution & Reporting Methodology: Complaints are unverified voluntary submissions to the NHTSA Office of Defects Investigation (ODI). Because multiple vehicle components can be cited within a single owner complaint submission, component-level rollups may sum to more than the unique complaint count (5). Injury and fatality entries in the detailed table reflect raw values entered by reporting consumers across individual submissions; they are not deduplicated casualty statistics and may include duplicate or unverified entries. Complaint volume is not normalized for sales volume or vehicle mileage and does not represent an audited component failure rate.

Formal safety defect inquiries and engineering analyses opened by the NHTSA Office of Defects Investigation (ODI)

Official Federal Inquiries: NHTSA opens a defect investigation when safety screening or consumer defect trends indicate a potential unreasonable safety risk. An open investigation is a formal inquiry and does not by itself confirm a defect or result in a mandatory recall.

Desiccated Air Bag Inflator Rupture

Affected Component: AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L.
