DETROIT (AP) — Mazda is recalling more than 60,000 midsize cars in the U.S. and Canada because a wiring problem can knock out power-assisted steering and the passenger air bag. The recall covers Mazda 6 sedans from 2015 and 2016. The company says in documents posted by the U.S. government that wires under the front passenger seat can rub against welding debris, causing them to short.
