U.S. safety regulators are warning owners of more than 4.7 million vehicles that have been recalled for air bag problems to get them repaired immediately.
The probe was opened over an April 2011 car crash that severely injured an elderly man when the passenger air bags didn’t deploy.
The company says circuits within the air bag control module can be damaged if they’re exposed to interference from other electrical components in the car.
Toyota is recalling 803,000 vehicles in the U.S. because their air bags or power steering could stop working.
Under government pressure, Ford Motor Co. said Wednesday it will recall nearly 150,000 F-150 pickup trucks to fix air bags that could deploy without warning.
