Tesla offers a standard driver assistance package called Autopilot in all its new cars today.
Another recent crash added to NHTSA's list involved a 2020 Tesla Model 3, the company's entry-level sedan.
According to data obtained from NHTSA by CNBC, the agency is looking into at least 41 crashes involving Tesla vehicles where automated features such as automatic emergency braking, or more extensive driver assistance system features included in Autopilot, FSD, and FSD Beta were involved.
The California DMV has accused Tesla of engaging in false advertising around its driver assistance systems.
Amid tough economic conditions, Tesla has recently offered steep discounts on its cars in the US, Canada, Mexico and China.
