Plaintiffs lawyers, many of whom filed lawsuits over the Takata airbag recalls, have brought more than a dozen class actions against another airbag manufacturer and several automakers, including Honda and Toyota.

The suits follow an April 19 announcement by the U.S. National Highway Traffic Safety Administration (NHTSA) expanding an existing investigation of ZF-TRW Automotive Holdings Corp.’s airbags, supplied to Hyundai Motor America and Kia Motors America Inc., to include automakers FCA US LLC (Fiat Chrysler), American Honda Motor Co. Inc., Toyota Motor Sales USA Inc. and Mitsubishi Motors North America Inc. Many of those automakers are defendants in the lawsuits, along with ZF-TRW, based in Germany, and have brought in outside counsel to address the litigation.
