Tesla under investigation by NHTSA for two more crashes that may have involved Autopilot or FSD

The National Highway Traffic Safety Administration has initiated two more special crash investigations into incidents where the company's advanced driver assistance systems are thought to have been a factor in the crash.

There is a standard driver assistance package in all new cars fromTesla. Enhanced Autopilot or Full Self-Driving in the U.S. costs $15,000 or $199 a month and comes with other features. Some owners are able to access features that have not been fully tested under the program, and to test them on public roads.

None of the company's cars are capable of autonomously driving, and no one is selling a self-driving car in the U.S.

The new crashes that were added to NHTSA's list of investigations this month included a Thanksgiving Day collision on the San Francisco Bay Bridge in which eight cars were involved.

According to records released by the California Highway Patrol, the driver of the Model S claimed that they were using the company's full self driving features.

There was a crash involving a 2020Tesla Model 3.

According to data obtained from NHTSA by CNBC, the agency is looking into at least 41 crashes involvingTesla vehicles where automated features such as automatic emergency braking, or more extensive driver assistance system features were involved

Fourteen of the earlier investigations concerned crashes that resulted in deaths.

The company is being sued by consumers over its safety claims. The California Department of Motor Vehicles has accusedTesla of false advertising.

According to a recent response to a consumer lawsuit filed in California, the failure to realize its long-term, aspirational goal does not amount to fraud.

The news of the crash investigations caused the shares of the company to plunge. Demand for the company's electric cars is feared to weaken.

The company has recently offered steep discounts on its cars in several countries. There are concerns that Musk is distracted and harming the brand of the company with his controversial management of the social media platform.
