Federal safety officials ordered Takata Corp. Tuesday to expand its recall of driver-side airbags from regional to nationwide. The National Highway Traffic Safety Administration received a report of a defective airbag outside the current recall areas in the United States, which is confined to those with persistently high humidity. NHTSA will force Takata to expand the recall if the Japanese safety equipment maker does not agree to do so voluntarily, NHTSA said in a press release.
