The National Highway Traffic Safety Administration (NHTSA) has launched a formal investigation into nearly 2.9 million Tesla vehicles due to safety concerns linked to the company’s Full Self-Driving (FSD) system. The probe, conducted by the agency’s Office of Defects Investigation, focuses on vehicles equipped with both the FSD (Supervised) and FSD (Beta) versions of the technology. According to NHTSA, these systems are designed to be used only with a fully attentive driver who remains actively engaged in the driving task at all times. The investigation follows reports of multiple traffic safety violations involving Tesla vehicles operating with FSD. These include vehicles running red traffic lights and making lane changes into oncoming traffic. The agency has documented 58 safety-related incidents tied to the system, including more than a dozen crashes and fires, as well as 23 injuries. The incidents were reported to NHTSA through various channels, including consumer complaints and crash data. NHTSA emphasized that the probe is not a determination of fault or a finding of defects, but rather a preliminary review to assess whether there is a reasonable probability that a safety-related defect exists in the vehicles. The investigation will examine the design, performance, and operational safety of the FSD system, particularly in scenarios where drivers may become over-reliant on automation. Tesla has not yet issued a public statement in response to the investigation. The company has previously maintained that its FSD system is designed to assist drivers, not replace them, and that it requires constant driver supervision. However, regulators and safety advocates have raised concerns about the potential for driver complacency and the risks posed by advanced driver-assistance systems when used improperly. The probe comes amid growing scrutiny of autonomous vehicle technologies across the industry. As automakers roll out increasingly sophisticated driver-assistance features, regulators are working to ensure that these systems are safe, reliable, and used responsibly. The outcome of the NHTSA investigation could lead to further actions, including recalls, software updates, or changes in how Tesla markets and deploys its FSD technology. This is a developing story and will be updated as more information becomes available.
