The Future on Hold? Why Federal Regulators Are Investigating Self-Driving Teslas
The promise of a car that drives itself is one of the most exciting advancements in modern technology. For years, Tesla has been at the forefront of this push with its “Full Self-Driving” (FSD) feature. However, a series of recent and serious incidents has put this technology under the microscope, prompting a major investigation by US auto safety regulators.
The National Highway Traffic Safety Administration (NHTSA) has launched a formal investigation into nearly 3 million Tesla vehicles equipped with FSD. This isn’t just a routine check-up; it’s a direct response to alarming reports of cars allegedly violating basic traffic laws, leading to crashes and injuries. Let’s break down what’s happening and why it matters for the future of self-driving Teslas.

What Prompted the NHTSA Investigation?
At the heart of the investigation are multiple reports of dangerous vehicle behavior while FSD was engaged. The NHTSA stated that the system had “induced vehicle behaviour that violated traffic safety laws,” a serious charge that questions the software’s reliability in real-world scenarios.

The agency is examining several specific and concerning patterns:
- Running Red Lights: The NHTSA has received six reports where a Tesla with FSD engaged approached a red light, failed to stop, and crashed with other vehicles in the intersection. Four of these crashes resulted in injuries.
- Driving Against Traffic: There are also reports of Teslas moving against the proper direction of travel during lane changes.
- Failure to Stop: Beyond outright crashes, the agency noted 18 complaints alleging that vehicles failed to remain stopped at a red light or didn’t stop completely.
This investigation is a “preliminary evaluation,” which is the first official step the NHTSA takes to determine if a technology poses an unreasonable risk to safety. If they find it does, it could lead to a massive recall of the self-driving Teslas in question.
FSD vs. Autopilot: Understanding the Difference
It’s crucial to understand what FSD is—and what it isn’t. Many people use “Autopilot” and “Full Self-Driving” interchangeably, but they are different systems.
- Autopilot: This is a standard feature on all new Teslas. It includes traffic-aware cruise control and autosteer, primarily designed for highway driving. It helps with steering, accelerating, and braking within a single lane.
- Full Self-Driving (FSD): This is an optional, premium add-on that expands on Autopilot’s capabilities. It aims to handle city street driving, including navigating intersections, making turns, and changing lanes automatically.
Despite its name, FSD does not make the vehicle fully autonomous. Tesla’s own website clarifies that it is “intended for use with a fully attentive driver, who has their hands on the wheel and is prepared to take over at any moment.” This new investigation raises questions about how effectively a driver can intervene when the system behaves erratically without warning.
A Pattern of Scrutiny
This isn’t the first time that self-driving Teslas have drawn the attention of regulators. This new probe adds to an existing investigation started in October 2024, which looked into 2.4 million Teslas with FSD after four collisions in low-visibility conditions like sun glare or fog. One of those crashes, tragically, was fatal.
The repeated scrutiny suggests a growing concern within the government about the readiness of advanced driver-assistance systems for public roads. While the goal is to improve safety, the performance of self-driving Teslas in these specific edge cases is now a major focal point.
What This Means for Tesla Owners and the Future
For the 2.88 million Tesla owners with FSD, this investigation is a stark reminder that the technology is still a work in progress. It underscores the critical importance of remaining vigilant and ready to take control at a moment’s notice.
For the broader auto industry, this is a pivotal moment. The outcome of the NHTSA’s investigation could set a precedent for how advanced driver-assistance systems are regulated in the future. It highlights the delicate balance between pushing for technological innovation and ensuring public safety on the roads. The performance of these self-driving Teslas will undoubtedly influence public trust and regulatory frameworks for years to come.
As the investigation unfolds, the world will be watching closely. The dream of a fully autonomous future is compelling, but getting there safely is the most important part of the journey. For now, the driver’s seat remains the most critical component of all self-driving Teslas.
Frequently Asked Questions (FAQs)
1. Why are self-driving Teslas being investigated?
The NHTSA is investigating because of multiple reports and crashes where Tesla vehicles with Full Self-Driving (FSD) engaged allegedly ran red lights, drove against traffic, and failed to stop at intersections.
2. Is Tesla’s Full Self-Driving (FSD) fully autonomous?
No. FSD is an advanced driver-assistance system (Level 2 autonomy). It requires a fully attentive driver with their hands on the wheel, ready to take over immediately. It does not make the car self-driving in all conditions.
3. What could happen as a result of this investigation?
If the NHTSA determines that the FSD system poses an unreasonable risk to safety, it could request that Tesla issue a recall to update the software or fix the potential defects.
4. How many Tesla vehicles are affected by this investigation?
The investigation covers approximately 2.88 million Tesla vehicles in the US equipped with the Full Self-Driving (FSD) assistance system.
