The agency said the investigation has been "opened to better understand the contributing factors and frequency of vehicle fires originating from the battery region of the
One report said that a RAV4 caught fire in Lyons, Colorado after the owner of a 2017 Toyota RAV4 hybrid was driving 50 miles per hour when the check engine light came on
and then white smoke emerged from beneath the hood.
