Toyota recalls 645,000 cars over flawed air bag system

Toyota has recalled about 645,000 cars worldwide., including the 2016 Prius, the Lexus RX and the 2015-2016 Lexus NX due to faulty air bag systems that may prevent the bags from inflating in a crash, AP reports.

The recalls include at least 49,000 vehicles in the U.S., including certain Prius, Lexus RX and NX SUVs, per Reuters. Toyota will notify affected owners by letter, starting in late March.
