NHTSA investigates comma.ai over 5 crashes

On September 21, 2026, NHTSA opened a formal investigation into comma.ai’s aftermarket driver-assistance devices after 5 crashes where cars running openpilot hit stopped or slow vehicles.

Two of those crashes killed three people, while four of them left 11 people injured. The federal probe covers an estimated 30,000 devices, including comma three, comma 3X, and comma four models. Some incidents may involve modified software versions known as forks.

This is the biggest regulatory problem for George Hotz’s startup since federal regulators pushed it to cancel its first product back in 2016.
