Tesla TSLA shares declined about 2% Monday morning as investors monitored a federal deadline tied to a U.S. safety probe into the company’s driver-assistance technology,

The National Highway Traffic Safety Administration (NHTSA) has requested information related to an investigation covering about 2.88 million Tesla vehicles equipped with the company’s Full Self-Driving systems, including FSD (Supervised) and FSD (Beta). The agency is examining reports of traffic violations involving the vehicles, such as running red lights, making illegal turns, and traveling the wrong direction.

The technology under review is classified as Level-2 driver assistance, meaning drivers must remain attentive and ready to take control at any time. Investigators are reviewing 58 reported incidents linked to the system, including 14 crashes that resulted in 23 injuries, though no fatalities were reported.

Tesla has been given until March 9 to provide the requested data after receiving two deadline extensions. NHTSA rules allow the agency to impose penalties of nearly $28,000 per day for non-compliance, up to a maximum of about $139.4 million.
