A stunning crash in Piedmont that killed three college students, leaving a third with severe injuries, has triggered deep suspicion of the vehicle involved: a Tesla Cybertruck, the electric pickup with a space-age look — and a history of engineering mishaps.

A fatal Tesla Cybertruck incident in Piedmont is being investigated by the National Highway and Traffic Safety Administration and California Highway Patrol after three Piedmont high school graduates died and another was hospitalized.

The National Highway and Traffic Safety Administration is in the process of reviewing details about last week's fatal Tesla Cybertruck crash in the Northern California city of Piedmont that left three young adults dead and a fourth critically injured.
