WASHINGTON (Reuters) – The National Highway Traffic Safety Administration (NHTSA) said Thursday it is upgrading its probe into 830,000 Tesla (NASDAQ:TSLA) vehicles with its advanced driver assistance system Autopilot.
The auto safety agency in August opened a preliminary evaluation to assess the performance of the system in 765,000 vehicles after a series of crashes in which Tesla vehicles struck stopped emergency vehicles. NHTSA is upgrading its probe to an engineering analysis, a required step before it could seek to compel a recall.
