The VinFast EV being driven by the Pleasanton family had steering problem before the deadly crash, according to a complaint filed to the NHTSA.

PLEASANTON, Calif. (KGO) — New details are emerging from the deadly car crash that killed a family of four in Pleasanton. A complaint to safety regulators raises concerns about the electric vehicle driven by the family — by car maker VinFast.

All four members of the George family – including two young children – died in the crash in Pleasanton nearly three weeks ago.

They ran into a large oak tree, then the car caught fire.

Records from the National Highway Traffic Safety Administration show days after the crash, someone filed a complaint about electric car maker VinFast with details seeming to match the Pleasanton crash.

The complaint writer says they are the owner of the car, and loaned it to a coworker – the driver in the crash.
