TeslaS Full Self-Driving System Under scrutiny: NHTSA Launches New Investigation into 2.88 Million Vehicles
By Maria Petrova,Leading content Strategist & SEO Expert
The U.S. National Highway Traffic Safety Administration (NHTSA) has escalated its oversight of Tesla’s advanced driver-assistance systems, announcing a formal investigation into 2.88 million vehicles equipped with the company’s Full Self-Driving (FSD) capability.This probe, launched on October 9th, 2025, comes amidst a growing wave of concerns regarding the system’s safety and performance, and follows a recent software update released by Tesla this week.
This isn’t simply a minor review; its a important growth with perhaps far-reaching consequences for Tesla and the future of autonomous driving technology. as a content strategist deeply immersed in the automotive tech space, I’ll break down what this investigation means, the specific issues prompting it, and what drivers and industry observers should expect.
What’s Driving the Investigation? A Pattern of Safety Concerns
The NHTSA investigation stems from over 50 reported incidents involving traffic safety violations linked to FSD, including a disturbing pattern of crashes. Specifically, the agency is focusing on reports detailing FSD causing vehicles to:
* Disregard Traffic Signals: Multiple reports, including six resulting in crashes, describe Tesla vehicles proceeding thru red lights at intersections.
* Erratic Lane Changes: Instances of vehicles driving against the flow of traffic during lane changes have also been documented.
* inconsistent Signal Recognition: One driver in Houston reported FSD consistently misinterpreting traffic signals, leading to dangerous situations – a problem they claim Tesla has acknowledged internally but failed to address.
* Railroad Crossing Concerns: NHTSA will also examine FSD’s behavior near railroad crossings, adding another layer to the safety assessment.
These incidents have resulted in 23 reported injuries and 14 crashes,prompting a preliminary evaluation – the first step towards a potential recall if NHTSA determines an unreasonable safety risk exists. The news promptly impacted Tesla’s stock price, with shares falling 2.1% in early trading.
A History of Scrutiny: Building on Previous Investigations
This isn’t the first time Tesla’s FSD has been under the NHTSA microscope. An ongoing investigation, initiated in October 2024, already covers 2.4 million vehicles, focusing on collisions occurring in conditions of reduced visibility (sun glare, fog, dust). This earlier probe included a fatal crash in 2023.
Furthermore, NHTSA is currently investigating 2.6 million Tesla vehicles related to crashes involving the remote vehicle summoning feature. And, the agency is actively reviewing tesla’s recent deployment of self-driving robotaxis in Austin, Texas, launched in June. This cumulative scrutiny highlights a clear pattern of concern regarding Tesla’s automated driving features.
Understanding Full Self-Driving: Assistance,Not Autonomy
It’s crucial to understand what Tesla’s FSD is and isn’t. Tesla markets FSD as a system capable of driving “almost anywhere with your active supervision, requiring minimal intervention.” However, the company explicitly states it does not make the car self-driving.
This distinction is vital. FSD is classified as an advanced driver-assistance system (ADAS), meaning it’s designed to assist the driver, not replace them. Drivers are legally and ethically obligated to remain attentive and ready to intervene at all times. The NHTSA investigation centers on whether FSD is inducing behaviors that undermine this essential principle.
The Broader Implications: A Wake-Up Call for the Industry
The NHTSA investigation isn’t just about Tesla. Oliver Carsten, a professor of transport safety at the University of Leeds, rightly points out that this should serve as a “wake-up call for Europe.” The automotive industry is witnessing a proliferation of ADAS features, and many systems are blurring the lines between driver assistance and true automation.
This raises critical questions about:
* System Transparency: How clearly are these systems communicating their limitations to drivers?
* Driver Monitoring: Are current driver monitoring systems effective enough to ensure attentiveness?
* Regulatory Frameworks: Are existing regulations keeping pace with the rapid advancements in autonomous technology?
What to Expect Next
NHTSA’s preliminary evaluation will involve a thorough review of the reported incidents, data analysis, and potentially further testing of the FSD system. Possible outcomes include:
* No Action: If NHTSA determines the incidents are isolated
