The problem of air bag inflators that can rupture and spew shrapnel into drivers and passengers could be widening beyond Japanese manufacturer Takata Corp

U.S. safety regulators are ordering Japanese auto supplier Takata Corp. to provide more information about air bags that can explode and shoot shrapnel toward drivers and passengers.

Two U.S. senators are calling on regulators to issue a nationwide recall of cars with faulty air bags made by Takata Corp., questioning why automakers have been allowed to limit recalls to only certain locations with high humidity.
