Key Takeaways

Federal safety regulators have advanced their Tesla Full Self-Driving investigation to an engineering analysis phase.
Approximately 3.2 million Tesla vehicles are included in the expanded probe — representing virtually every Tesla sold domestically.
Regulators have identified nine collisions connected to the concern, with one resulting in a fatality and two causing injuries.
Investigators are examining Tesla’s visibility detection system, designed to alert drivers when camera performance deteriorates.
This advancement in the investigation could result in a vehicle recall or additional regulatory measures if safety deficiencies are confirmed.

Federal transportation safety officials have elevated their examination of Tesla’s Full Self-Driving technology, transitioning to a comprehensive engineering analysis that may culminate in a vehicle recall. The expanded investigation encompasses approximately 3.2 million vehicles — representing nearly Tesla’s complete domestic sales history.

Tesla, Inc., TSLA

Shares of Tesla (TSLA) declined 1.63% when the announcement became public.

The regulatory focus targets FSD’s visibility monitoring capabilities. This system should identify compromised camera performance — including conditions such as direct sunlight, atmospheric haze, or obstructions — and prompt drivers to assume manual control.

According to NHTSA, evidence under review suggests the system has not performed this critical function adequately, both prior to and following software modifications.

Nine collisions have been associated with this concern. One crash proved fatal. Two additional incidents caused physical injuries.

In accidents examined by federal authorities, the FSD technology failed to identify circumstances that impaired camera function. In several instances, warnings were only triggered moments before collision — providing drivers insufficient opportunity to intervene.

Regulators also discovered additional crashes in comparable low-visibility scenarios where the system completely failed to recognize degraded visibility or provided inadequate warning time for safe driver response.

Tesla’s internal post-crash evaluation indicated that a software enhancement to the visibility detection system might have altered outcomes in three of the nine collisions — had that enhancement been deployed earlier.

Tesla has not issued a statement in response to inquiries.

Understanding the Engineering Analysis Phase

An engineering analysis represents a more thorough stage of federal oversight. This phase empowers NHTSA to obtain comprehensive technical data from the manufacturer and conduct extensive examination of possible defects.

Should the agency determine a safety deficiency exists, it possesses authority to mandate a recall or implement alternative enforcement measures. Tesla has encountered numerous NHTSA investigations in recent years examining different components of its automated driving capabilities.

Implications for Tesla

Tesla’s complete self-driving strategy — including its anticipated autonomous taxi network — relies on maintaining regulatory approval and public confidence in FSD technology.

Any potential recall affecting 3.2 million vehicles would rank among the most substantial in the company’s history and would intensify scrutiny on technology Tesla has positioned as fundamental to its long-term vision.

NHTSA’s investigation advancement continues a trend of heightened regulatory oversight of FSD. During the final months of 2024, the agency initiated a distinct investigation into FSD collisions occurring under diminished visibility circumstances, which encompassed four incidents including one death.

Tesla had not released any public statement regarding the investigation escalation as of Thursday evening.
