In a recent filing, Tesla has disclosed that the U.S. Department of Justice (DOJ) has initiated multiple investigations and issued subpoenas regarding various aspects of the electric vehicle (EV) giant's operations. The filing, released on Monday, revealed that the DOJ is scrutinizing Tesla's vehicle range claims, personal benefits, related parties, and personnel decisions.

Specific details regarding the related parties were not provided in the filing, but typically, this term encompasses a company's executives, directors, largest shareholders, and sometimes other businesses affiliated with them. The Wall Street Journal previously reported that federal prosecutors were investigating if Tesla utilized company funds to construct a project referred to as a "glass house" for CEO Elon Musk. Moreover, Reuters has previously reported on a federal criminal investigation into Tesla's self-driving claims.

The investigations have also expanded to include Tesla's driver assistance systems, Autopilot and Full Self-Driving (FSD). The DOJ has been seeking information about these systems marketed by the company. Additionally, the range of Tesla's EVs has come under scrutiny, as it has been reported by Reuters and verified by studies conducted by Recurrent and others that the actual mileage often falls short of the estimates provided by the company.

Tesla's disclosure also mentioned a data breach incident, resulting in lawsuits filed against the company. The breach involved the leak of customer complaints regarding Tesla's driver assistance features, which were reported by a German news outlet, Handelsblatt, earlier this year. The disclosure stated that a "foreign news outlet obtained certain misappropriated data."

The heightened regulatory scrutiny faced by Tesla and its affiliated companies appears to have prompted Elon Musk to call for "comprehensive deregulation" over the weekend. Besides being CEO of Tesla, Musk also leads SpaceX and serves as the chief technology officer of X Corp., formerly known as Twitter.

Following a decline of around 15% last week after a pessimistic third-quarter earnings call, Tesla's shares experienced a slight recovery on Monday afternoon. During the call, Musk and other executives discussed increased research and development (R&D) expenditures and expressed concerns about the potential impact of higher interest rates on consumer demand for new cars.

The third-quarter filing was signed by Tesla's Chief Financial Officer (CFO), Vaibhav Taneja, who assumed the role in August. The filing also revealed that the former CFO, Zachary Kirkhorn, will continue to receive payment, though the company redacted his exit date.

As the DOJ investigations progress, Tesla faces further scrutiny over various aspects of its operations, including vehicle range claims, personal benefits, related parties, personnel decisions, and the functionality of its driver assistance systems. The outcomes of these investigations could potentially have significant repercussions for the EV giant moving forward.
