Key Takeaways
The federal traffic safety regulator is intensifying its investigation into Tesla's Full Self-Driving (FSD) technology, which has escalated to a full engineering analysis phase that could ultimately lead to a vehicle recall. This expanded investigation covers approximately 3.2 million vehicles, nearly encompassing all of Tesla's sales in the U.S.
The regulatory focus is on the visibility monitoring function of the FSD system. This system is supposed to detect situations where camera performance is compromised, such as direct sunlight, atmospheric haze, or obstructions, and promptly alert the driver to take manual control.
According to the National Highway Traffic Safety Administration (NHTSA), evidence under review indicates that the system has failed to effectively execute this critical function both before and after software updates.
Among the nine collision incidents involved in the investigation, one resulted in a fatality, and two others caused injuries.
Federal investigators found that the FSD technology failed to recognize harsh environmental conditions affecting camera functionality. In several incidents, the system issued warnings with little time to spare, just seconds before collisions, making it difficult for drivers to react in time.
The regulators also determined that in similar low-visibility scenarios, the system exhibited flaws in recognizing reduced visibility or failed to provide sufficient warning time, increasing safety risks.
As of now, Tesla has not publicly commented on the ongoing investigation.
Details on the Engineering Analysis Phase
The engineering analysis is a deeper review phase by federal regulators, allowing the NHTSA to request comprehensive technical documentation from manufacturers and conduct detailed inspections of potential defects.
Impact on Tesla
Tesla's Full Self-Driving strategy, including its planned autonomous taxi network, relies on ongoing approvals from regulators and public trust in FSD technology.
If the recall encompasses 3.2 million vehicles, it would become one of the largest recalls in Tesla's history and intensify scrutiny on its core technology.
The NHTSA's escalation of the FSD investigation continues a trend of increased regulatory scrutiny in recent years. By the end of 2024, the agency also initiated an independent investigation into several FSD-related incidents under low-visibility conditions, including one fatal accident.
As of the night the investigation was escalated, Tesla had not issued a public statement regarding the matter.
