Statement On Safety Recall 4821C Of MY2007-2009 Mazda B-Series Vehicles
Driver Frontal Air Bag May Explode In Crash

WASHINGTON, DC. (March 12, 2021) – Mazda North American Operations (MNAO) has filed a defect notification with the National Highway Traffic Safety Administration (NHTSA) for a safety defect, which exists in MY2007-2009 B-Series vehicles equipped with Takata PSDI-5D driver air bag inflators. In the event of a crash that causes the driver frontal air bag to deploy, an inflator explosion may cause sharp metal fragments to pass through the air bag and into the vehicle interior at high speed, which may result in serious injury or death.

TK Holdings, Inc. (“Takata”) has determined that a defect which relates to motor vehicle safety exists in the driver frontal air bag inflators installed as original equipment of the MY2007-2009 B-series. The PSDI-5D inflators may potentially explode during normal air bag deployment due to degradation of the propellant desiccated with calcium sulfate. Inflator degradation can occur after prolonged exposure to high humidity and temperature cycling. There is no warning prior to occurrence.

Approximately 5,844 MY2007-2009 Mazda B-Series vehicles, produced at the Twin Cities Assembly Plant of Ford Motor Company, are affected.

No accidents or injuries have been reported as a result of this defect.

Affected owners will be notified by mail. Please check or for the latest updates.
