Tesla Autopilot Claim in Fatal Katy Crash Hits 3.2 Million-Vehicle Recall Probe

Tesla Autopilot Claim in Fatal Katy Crash Hits 3.2 Million-Vehicle Recall Probe centers on a fatal crash in Katy, Texas, where a driver reported the Tesla was on Autopilot at impact. The incident occurred at about 8 p.m. on June 20, 2026, when a Tesla Model 3 drove through the brick front of a home, killing Martha Avila Mantilla, 76, who was in the front room. Michael Butler, 44, told Harris County deputies the vehicle was on Autopilot; investigators are now verifying the claim using onboard event data. The case aligns with a high-stakes NHTSA investigation into Tesla driver-assistance technology covering 3.2 million vehicles, recently advanced to Engineering Analysis status, the stage just before a recall request. Video shows the car accelerating down Rose Hollow Lane before striking a curb and the two-story facade. Authorities said Butler failed to stay in a single lane and did not complete a required right turn. Investigators also reported no intoxication signs and no charges as of Sunday morning.
