The parents of Star Trek actor Anton Yelchin are planning to sue the companies they believe are responsible for his death. Yelchin was found dead in June after his Jeep Grand Cherokee rolled and pinned him against a security gate in Los Angeles. The Like Crazy star’s parents are seeking punitive damages “for the wrongful death of their son due to significant defects” in the vehicle, TMZ reports. A class-action suit has already been filed against automaker Fiat Chrysler with claims the model had a faulty e-shift that led drivers to believe the vehicle was safely in park when it was, in fact, in neutral. The Yelchins’ suit will reportedly seek damages from Fiat Chrysler, AutoNation, and ZF North America.
