In two actions, Toyota is recalling a little over 1 million vehicles, including 752,000 for air bags that could be set off by electronic interference, the automaker has informed the National Highway Traffic Safety Administration.
In a letter dated Wednesday, Toyota told the safety agency that the company was recalling the 2003-04 Corolla, Corolla Matrix and Pontiac Vibe, a mechanical sibling of the Matrix, because of the problem.
The action includes almost 604,000 Corollas, 148,000 Matrix models and almost 136,000 Vibes, with the latter being recalled by General Motors.
Toyota told the agency that the front air bags on those vehicles were susceptible to a short that could cause the bags to trigger without the vehicles being in an accident.
Toyota's report says the air bag control module can suffer a short circuit "when exposed to high inductive electrical noise from various vehicle electrical components."
The automaker says it will install a noise filter to resolve the problem.
The second action covers about 270,000 Lexus IS vehicles.
Toyota says a nut on the windshield wiper arm may not be tight enough and one or both wipers can stop moving if the arms face resistance, like pushing snow out of the way.
The recall covers the 2006-12 IS 250 and IS 350; 2010-12 IS 250C and IS 350C and 2008-11 IS-F models.
Toyota describes its actions as voluntary, but once an automaker is aware of a safety problem it must -- within five business days -- inform the agency of its plan for a recall or face a civil fine.
