The federal government has given Tesla quite the homework assignment. The electric automaker has until July 1 to reply to a massive data request from the National Highway Traffic Safety Administration, which is investigating the efficacy of Tesla’s massive Autopilot recall, following at least 20 crashes post-recall.

Tesla decided to recall more than 2 million cars in the US—almost every vehicle it has ever sold here—in December 2023, following an engineering analysis by NHTSA that found the automaker’s Autopilot driver assistance feature had inadequate driver monitoring and that Autopilot was too easily misused.

Last month, we discovered that NHTSA is not happy with the Autopilot recall. Now, the agency has made public the letter it sent Tesla this week, demanding a whole lot of answers by July 1.
