Tesla (TSLA) shares are sinking following reports that the Justice Department (DOJ) is investigating whether the company committed securities and wire fraud in its self-driving claims, according to Reuters. Yahoo Finance Senior Autos Reporter Pras Subramanian weighs in on the information the DOJ is searching for in this investigation. The DOJ investigation adds another layer to the issues currently hitting Tesla, from weakening demand for electric vehicles to unclear robotaxi plans. The company has been leaning into messaging around its "Full Self-driving" technology despite consumer skepticism, and news of the investigation may only heighten investor and consumer concerns.
