A wrongful-death suit filed days after a Model 3 ploughed into a Katy home leans on the same argument that produced last year’s $243m Florida verdict.
The family of a 76-year-old woman killed when a Tesla crashed through the wall of her home near Houston has sued the carmaker and the driver, less than a week after the crash.
The wrongful-death suit, filed in Harris County District Court by Jennifer and Justin Barbour, the daughter and son-in-law of Martha Avila, names Tesla and 44-year-old driver Michael Butler as defendants and seeks more than $1m plus punitive damages.
It is the latest test of whether Tesla can be held liable for what its driver-assistance software does.
The crash itself is not in dispute. According to the petition, Butler was driving a Model 3 eastbound on Rose Hollow Lane at about 8pm on June 19 when the car left the road and crashed through the front wall of the Barbour family home.
Avila, standing in the front room, was airlifted to a hospital and pronounced dead of her injuries. Justin Barbour, also inside, was hurt, and the family says the home is now unliveable.
What is in dispute is what the car was doing. Butler told the Harris County Sheriff’s Office that an automated driving system was engaged, a claim the lawsuit repeats but investigators have not confirmed.
The same office said it found no evidence of a mechanical malfunction and that Butler, not intoxicated, has cooperated.
The crash already sits inside the National Highway Traffic Safety Administration’s special crash investigation, which will pull the event data recorder independently.
The complaint accuses Tesla of design defect and failure to warn, and the driver of negligence and gross negligence.
It alleges the vehicle failed to detect the end of the street and the house in its path, failed to monitor whether the driver was paying attention, and failed to warn owners about the limits of Autopilot and Full Self-Driving, with “sudden unintended acceleration” offered as an alternative theory. The family is represented by Chris Adkins of Zehl & Associates.
Tesla has already argued the opposite in public, before any court date. Ashok Elluswamy, the company’s head of AI software, posted that vehicle data shows Butler “manually overrode self-driving by pressing the accelerator all the way to 100% of the accel pedal in this residential area,” reaching 73mph, and Elon Musk added that “FSD drives slowly through neighbourhood streets and this was a high speed crash.”
That points to pedal misapplication, the driver hitting the accelerator instead of the brake, which would normally be a complete defence.
That defence no longer settles the question, because of a courtroom in Florida. In August 2025, a Miami federal jury found Tesla partly responsible for a 2019 Key Largo crash in which a driver using Autopilot ran a T-intersection at roughly 62mph while reaching for a dropped phone, killing 22-year-old Naibel Benavides Leon.
The jury put most of the fault on the driver but still held Tesla liable for its share, about $243m, and a federal judge upheld the judgment in February.
The Texas plaintiffs have drawn the lesson that driver misuse and corporate responsibility can coexist.
Whether the argument lands here is harder. A 100% accelerator input is a more aggressive action than reaching for a phone, and Tesla’s lawyers will argue it breaks the chain of causation.
The suit arrives at an awkward moment regardless. NHTSA escalated its analysis of more than three million Teslas equipped with Full Self-Driving in March, and the company’s own driverless robotaxi fleet in Austin has reported a crash rate roughly four times worse than the human average it cites on its safety page.
The case is at its earliest stage, and the parties will fight over the vehicle data the family has asked the court to preserve. In Florida, Tesla initially told plaintiffs the crash data did not exist until an independent researcher recovered it.
The event data recorder will do more to settle what happened on Rose Hollow Lane than anything either side has posted so far.
