WASHINGTON, May 20 (Reuters) - U.S. auto safety

investigators said Monday they will investigate a VinFast VF 8

crash in April in Pleasanton, California, in which a family of

four died.

The National Highway Traffic Safety Administration said the

investigation will probe the April 24 crash circumstances and

the ensuing fire. A complaint filed with the agency said

steering may have been an issue in the fatal crash.

TechCrunch reported the investigation earlier.
