What happened
After a fatal crash on June 20, 2026 in Katy, Texas — in which a Tesla left the road and struck a home, killing a woman inside — U.S. regulators escalated their review of Tesla’s Full Self-Driving software. The crash feeds NHTSA’s existing engineering analysis covering roughly 3.2 million vehicles (2017–2026 Model 3 sedans), alongside a separate evaluation of about 2.88 million Teslas for traffic-law violations. Tesla shares closed up slightly on the announcement day, then fell 5.79% on June 24 as scrutiny grew.

What they said
"[The vehicle] was on Autopilot." — the driver, as told to sheriff’s deputies (per Electrek)
Why it matters
- Scale of the probe. Covering 3.2 million vehicles, it is among the largest U.S. driver-assistance reviews.
- Robotaxi timing. The scrutiny lands as Tesla expands its robotaxi ambitions.
- Safety vs. autonomy. It sharpens the central question of how far hands-off driving can go, and how regulators respond.
