Tesla Crash in Katy, Texas: One Dead, Driver Claims Autopilot Use
A 76-year-old woman was killed when a Tesla Model 3 crashed into her home Friday night. The driver says the car was on Autopilot—Tesla executives dispute that claim.
Incident Overview
On Friday night, a Tesla Model 3 crashed into a residence in Katy, Texas, killing a 76-year-old woman inside the home and injuring the driver. The National Highway Traffic Safety Administration (NHTSA) has launched a Special Crash Investigation into the event.
The driver reportedly told authorities he was using an automated driving system at the time of the crash—a claim Tesla executives have disputed.
What Happened
The crash occurred at approximately 20:00 local time in a residential area of Harris County. The driver, identified as Michael Butler, was operating a Tesla Model 3 when the vehicle left the roadway and struck a brick home.
The collision killed 76-year-old Martha Avila, who was inside the residence. She was airlifted to a hospital but later died from her injuries. Her daughter discovered her after the crash. The driver was also injured and hospitalized.
The driver showed no signs of intoxication and has been cooperating with authorities.

According to a police report, the driver failed to drive in a single lane. Butler told sheriff's deputies that the vehicle's accelerator was pressed fully during and after the crash, with the car reaching a speed of 73 mph (117 km/h).
Driver Statements vs. Tesla Response
The driver told authorities that the vehicle was operating on Autopilot at the time of the crash.
Tesla Vice President of AI Software Ashok Elluswamy stated on X that the driver manually overrode the self-driving system by pressing the accelerator pedal to 100%, leading to the high speed. Tesla CEO Elon Musk amplified this statement, asserting that the crash was high-speed and that the Full Self-Driving (Supervised) system operates at low speeds in neighborhoods. Elluswamy did not provide a source for his characterization of the driver's actions.
Ongoing Investigations
The NHTSA has launched a Special Crash Investigation—its most in-depth form of inquiry. This is separate from the local police investigation.
Sergeant Alex Turman of the Harris County Sheriff's Office stated that one line of investigation is the driver's claim that he was using an automated driving system. The Sheriff's Office will present its findings to the district attorney for potential criminal charges.
A law firm representing Avila's family has announced plans to file a lawsuit.
System Context
Tesla markets its Full Self-Driving (Supervised) technology as a key selling point but requires constant human supervision. In January 2025, Tesla discontinued the "Autopilot" name for its driver-assistance system after a California court ruling deemed the term misleading. Current driver-assistance systems are marketed under the Full Self-Driving (Supervised) name.
Broader Regulatory Landscape
The NHTSA had previously opened investigations into Tesla's self-driving technology following multiple reported incidents.
- December 2023: Tesla recalled over 2 million vehicles to improve driver attentiveness features when Autopilot is engaged.
- Earlier this year: NHTSA expanded an investigation into Full Self-Driving performance in inclement weather.
- Last week: U.S. Senators Edward Markey and Richard Blumenthal sent a letter requesting NHTSA investigate Tesla's Full Self-Driving technology for safety risks, citing concerns about data analysis methods.
Companies including Tesla, Waymo (owned by Alphabet), and Uber continue to test autonomous vehicle technology. Waymo recently recalled thousands of vehicles in Texas due to issues related to avoiding flooded roads.
