NHTSA is expanding a probe into potentially defective airbags to 12.3 million vehicles, according to autonews.com
The federal vehicle safety agency said the airbags were installed in some vehicles from model year 2010 through 2019.
Those vehicles were sold by Fiat Chrysler, Honda, Hyundai, Kia, Mitsubishi and Toyota.
The agency said they could fail during a crash event.
The agency, which first opened a probe in 2018, has reports of two crashes and two injuries related to the defect along with one death in a Toyota.
