Tesla (TSLA) is facing a probe by the National Highway Traffic Safety Administration, or NHTSA, regarding the adequacy of its recall for over 2 million vehicles announced in December to install new Autopilot safeguards.

The auto safety regulator said Thursday it launched an investigation due to concerns arising from crash events after the recall software update, "and results from preliminary NHTSA tests of remedied vehicles."

NHTSA also noted Tesla's statement that part of the remedy "requires the owner to opt in and allows a driver to readily reverse it."

The regulator noted Tesla's issuance of software updates to address the issues related to its concerns but the investigation will consider "why these updates were not a part of the recall or otherwise determined to remedy a defect that poses an unreasonable safety risk."

The recall investigation includes Model Y, X, S, 3, and Cybertruck vehicles in the US with Autopilot, spanning from the 2012 to 2024 model years, according to a Reuters report.
