Automakers sued over faulty airbags made by Takata Corp. have asked a federal judge in the Southern District of Florida to halt the litigation for at least six months, arguing that the U.S. National Highway Traffic Safety Administration, and not the courts, has “primary jurisdiction” over claims brought by consumers.

The automakers’ July 17 stay motion—which pertains only to the consolidated class action complaint filed by consumers and not to lawsuits filed on behalf of those who were injured or died—is an unusual twist in massive litigation involving an automotive defect.
