US traffic safety regulators have escalated their scrutiny of Tesla’s Full Self-Driving program following a series of social media posts by CEO Elon Musk that appear to overstate the system’s operational limits. On July 2, the National Highway Traffic Safety Administration issued a formal information request to the electric vehicle maker, seeking clarification on Musk’s public statements regarding automated driving assistance. Among the flagged messages is a December 2025 post in which Musk claimed drivers could safely text or prepare coffee while the vehicle navigates traffic, alongside broader assertions that the technology will substantially reduce driver attention and function reliably across all conditions. In its July directive, regulators asked Tesla to confirm whether these promotional examples accurately reflect the software’s actual performance and to detail any internal measures implemented to prevent consumer misunderstanding. This inquiry directly contrasts with Tesla’s official owner manuals and website disclaimers, which explicitly mandate that drivers must remain attentive and ready to assume manual control at all times during FSD supervision. The latest regulatory action underscores a persistent challenge surrounding Tesla’s product communication strategies. The automaker recently settled a wrongful-death lawsuit for $242 million after a jury found its advertising materially exaggerated the capabilities of Autopilot and FSD. Additionally, the company negotiated a settlement with California authorities in February to avoid a court-ordered branding ban after a judge determined that the terminology was inherently misleading to consumers. Parallel to these marketing concerns, the NHTSA probe initiated in October 2024 and elevated to a formal engineering analysis in March remains focused on FSD safety protocols in degraded visibility. Federal investigators are currently evaluating multiple crash reports involving Tesla vehicles striking obstacles in areas obscured by sun glare, fog, or airborne particulates. While regulators continue to evaluate both the technical performance and the communicative framing of Tesla autonomous features, the company has not yet provided a public response regarding the July information request.
