Tesla is once again facing legal scrutiny over its safety technology. While the company has dealt with numerous lawsuits in recent years – particularly over its door handle designs – its Autopilot and Full Self-Driving systems haven’t escaped controversy either. According to Forbes, Tesla’s driver-assistance technology has been linked to at least 51 reported fatalities since the first fatality was reported back in 2016. The latest case centers on a fatal Idaho crash involving a Tesla Model X that killed four members of a Utah family – and their dog – in September 2023. The wrongful death lawsuit, filed on August 28, 2025, alleges Tesla overstated the real-world capabilities of its driver-assistance systems, creating a false sense of security that may have contributed to the crash. More than two years after the incident, the case is now moving through Utah’s Third Judicial District Court.
The Fatal Crash
The crash occurred on September 1, 2023, shortly before 10 p.m. on Idaho State Highway 33 near milepost 125. According to court filings, the family’s 2022 Tesla Model X crossed the center line and collided head-on with an oncoming Kenworth semi-truck hauling grain. Killed at the scene were driver Jennifer Blaine, 46; her daughters Emily Blaine Leavitt, 22, and Denali Blaine, 11; Emily’s husband, Zach Leavitt, 24; and the family dog, Peaches. All occupants were wearing seat belts. The truck driver was not physically injured. The family had reportedly stopped in Idaho Falls to eat and charge the vehicle before continuing toward Driggs, Idaho, where they planned to camp.
Claims of Defective Safety Technology

Filed by Jennifer’s husband, Nathan Blaine, the lawsuit alleges the Model X was “unreasonably dangerous and defective” due to ineffective driver-assistance features. These include Autosteer, Lane Departure Warning, Lane Keeping Assist, Lane Centering Assistance, and Emergency Lane Departure Avoidance. According to the complaint, the systems failed to keep the vehicle in its lane or provide adequate warnings, despite being marketed as capable of detecting lane markings and correcting unintended departures. The suit also claims Tesla exaggerated the maturity and safety of its technology through marketing and public statements. Attorney Lynn Shumway told The Independent that while the technology itself shows promise, it was implemented "inadequately,” particularly on what he described as a “normal and pretty simple” stretch of road.
Not an Isolated Case for Tesla

Tesla has not publicly commented on the case. Whether Autopilot was engaged at the time of the crash remains disputed, though the lawsuit argues key safety systems should function regardless. But many similar lawsuits have come to light over the years. Families have previously sued Tesla over fatal Model S fires, alleging victims were trapped inside due to door handle failures. A recent Bloomberg investigation found at least 15 deaths tied to faulty electric door handles. As the Idaho case moves forward, it adds to growing pressure on Tesla to ensure its safety tech performs as promised.
