Takata plans to shift production of BMW airbag inflators from Mexico to Germany, BMW said on Wednesday in a filing with U.S. safety regulators who have been probing questions about the quality of manufacturing at the plant.

Automakers that use the Takata inflators, including Toyota, warned that it was not feasible to switch to other suppliers to meet demand for replacement parts. The Takata inflators are at risk of blowing up with too much force and spraying occupants with metal shrapnel.
