The driver said the car was using Autopilot; Tesla says its data show he pressed the accelerator to full. The US National Highway Traffic Safety Administration (NHTSA) has opened a special crash investigation into a fatal collision in Katy, Texas, in which a Tesla Model 3 left a residential road and struck a house, killing a woman inside. The agency said on Monday, June 22, that it was examining the June 20 crash, [according to CNBC](https://www.cnbc.com/2026/06/22/tesla-nhtsa-model-3-crash-autopilot-katy-texas.html) and [Electrek](https://electrek.co/2026/06/22/nhtsa-tesla-katy-crash-federal-investigation/). ## What is known about the crash The Model 3 left the road at around 8 p.m. local time and tore through the front of a home, where it struck a woman standing in a front room, [KHOU](https://www.khou.com/article/news/local/national-highway-traffic-safety-administration-investgate-tesla-crash-katy-fatal/285-b6fe0577-11a2-46f0-9419-ecd09c5b29c8) reported. The woman who died was named in local reporting as Martha Avila Mantilla, 76; relatives said she had been in good health. The driver, identified as 44-year-old Michael Butler, was reported to be cooperating with investigators. No charges had been filed as of the reporting reviewed for this story. ## Competing accounts What was controlling the car is disputed. The driver told sheriff's deputies the vehicle was using Tesla's Autopilot system at the moment of impact, the accounts that prompted NHTSA's review say. Tesla, however, has pushed back. The company's head of artificial intelligence, Ashok Elluswamy, said Tesla's data show the driver "manually overrode" the system by pressing the accelerator fully, with the car reaching about 73 mph and the pedal remaining depressed even after the crash, according to CNBC and Electrek. newsparlor could not independently verify either the driver's account or Tesla's data; the contradiction is precisely what investigators will seek to resolve from the vehicle's logs. ## What the investigation covers NHTSA's Office of Defects Investigation routinely opens special crash investigations to gather data on individual collisions; doing so does not establish a defect or assign blame. Investigators are expected to retrieve the vehicle's event data recorder to determine whether a driver-assistance system was engaged, the car's speed, and the driver's inputs in the seconds before the crash. It is important to be precise about the technology. Tesla markets two so-called Level 2 driver-assistance products — Autopilot and "Full Self-Driving (Supervised)." Neither makes the car autonomous; both require an attentive driver who can take over at any time. ## A wider federal review The Katy crash arrives amid a broader federal review of Tesla's driver-assistance technology. In March, NHTSA upgraded an investigation into Tesla's Full Self-Driving system to an "engineering analysis" — the procedural step that precedes any formal recall demand — covering roughly 3.2 million vehicles, including 2017–2026 Model 3 sedans, the model involved in the Texas crash. A separate evaluation has examined reports of Teslas committing traffic violations such as running red lights. Tesla, which has largely disbanded its press office, did not provide a broader public statement in the coverage reviewed beyond Elluswamy's account of the data. The question of whether any automated system was active — and whether it contributed to the crash — will rest on the vehicle's data rather than on accounts given in the immediate aftermath. ## Sources - [NHTSA probes fatal Tesla crash into Texas home that killed woman](https://electrek.co/2026/06/22/nhtsa-tesla-katy-crash-federal-investigation/) - [Tesla faces federal probe after Model 3 slams into Texas home, killing 76-year-old](https://www.cnbc.com/2026/06/22/tesla-nhtsa-model-3-crash-autopilot-katy-texas.html) - [NHTSA investigating after Tesla crashes into Katy-area home, killing woman inside](https://www.khou.com/article/news/local/national-highway-traffic-safety-administration-investgate-tesla-crash-katy-fatal/285-b6fe0577-11a2-46f0-9419-ecd09c5b29c8)
