The family of a 76-year-old woman killed when a Tesla Model 3 crashed into her Katy, Texas, home has sued Tesla and the driver, alleging the company’s “Autopilot” and “Full Self-Driving” systems are defectively designed.

The wrongful death suit lands just days after the crash — and it leans on the same argument that produced last year’s landmark $243 million Autopilot verdict against Tesla in Florida.

Tesla now confirms that its self-driving system was engaged when a Model 3 left a residential road in Katy, Texas, and killed a 76-year-old woman inside her home — but the company says the driver overrode it by pressing the accelerator to 100%.

Everything points to a pedal misapplication while the car was under “Full Self-Driving.” Does that mean Tesla is not at fault?

Federal safety regulators are now investigating the fatal Tesla crash in Katy, Texas, where a Model 3 left a residential road, tore through a brick home, and killed a 76-year-old woman inside.

The National Highway Traffic Safety Administration said Monday it is examining the June 20 crash, after the driver told deputies his Tesla was on Autopilot at the moment of impact.
