More than 30 million U.S. drivers unaware dangerous airbag threat

More than 30 million U.S. drivers have vehicles that contain a potentially deadly threat. The danger includes airbag inflators that in rare cases, can explode in a collision and spew shrapnel. Few of them know it. And because of a dispute between federal safety regulators and an airbag parts manufacturer, they aren’t likely to find out anytime soon. The National Highway Traffic Safety Administration is demanding that the manufacturer, ARC Automotive of Knoxville, Tennessee, recall 67 million inflators. But ARC is refusing to do so, setting up a possible court fight with the agency.
