US agency upgrades probe into Tesla's power steering loss into engineering analysis

SAN FRANCISCO (Reuters) - U.S. safety regulators said they have upgraded their probe into Tesla vehicles over power steering loss to an engineering analysis - a required step before they could potentially demand a recall.

The National Highway Traffic Safety Administration (NHTSA)said on Thursday that an estimated 334,569 2023 Model 3 and Model Y vehicles are subject to the engineering analysis.
