The DOJ first launched the probe back in 2021 after numerous crashes – some of which were fatal – involving the $15,000 Autopilot system. Regulators are looking into whether or not the system’s design and capability claims gave drivers a false sense of security, which led them to not paying enough attention behind the wheel of their Tesla.

The acting National Highway Traffic Safety Administration chief, Ann Carlson, told Reuters that the agency is “working really fast” on the investigation which she called “very extensive.” In June of 2022, NHTSA upgraded its probe to an engineering analysis that is taking a look at 830,000 Teslas with Autopilot.
