Toyota is recalling 601,000 more vehicles in the United States to replace defective and potentially deadly Tak ata air bag inflators. The US recall covered the Toyota Corolla and Matrix, Scion xB, Lexus IS250 and 350, and the Lexus IS-F from 2009, 2010 and 2013. Also covered are the 2010 and 2013 Toyota 4-Runner, Lexus IS250C and 350C and Lexus GX460, as well as the 2009 and 2010 Toyota Yaris and Lexus ES350, and the 2013 Toyota Sienna. The recalls come after Japanese company Takata revealed that another 3.3 million inflators were defective. Its inflators can explode with too much force and hurl shrapnel. At least 20 people have died worldwide and more than 280 have been hurt. Owners will be notified in March and dealers will replace front passenger inflators or air bag assemblies. Toyota announced that an extra 4,313 Corolla and 1,490 Yaris New Zealand new vehicles manufactured in 2009 were included in the recall. More than 100,000 new and used vehicles in New Zealand have so far been recalled.
