From the National Highway Traffic Safety Administration (NHTSA):
October 20: NHTSA urges owners of certain Toyota, Honda, Mazda, BMW, Nissan, and General Motors vehicles to act immediately on recall notices to replace defective Takata airbags. The message comes with urgency, especially for owners of vehicles affected by the regional recalls in the following areas: Florida, Puerto Rico, Guam, Saipan, American Samoa, Virgin Islands and Hawaii.
More than 4 million vehicles are implicated, reports the Washington Post here. As the Post describes the safety issue, "At least four people have died when inflator mechanisms ruptured on the air bags, spraying the passengers with metal fragments."
Look and see if your vehicle is affect by entering the VIN at www.safercar.gov/vinlookup. (Seriously. You should do this.)
