A federal appeals court has thrown out an order that let California Tesla owners band together to sue the automaker over its Full Self-Driving marketing, ruling Friday that the case cannot move forward as a class action. The U.S. 9th Circuit Court of Appeals found that individualized questions about what each buyer actually saw before purchasing their vehicle made class treatment improper, leaving thousands of California buyers unable to pursue their claims jointly in a single case, for now.
The ruling is a significant procedural win for Tesla, though it stops short of resolving whether the company's marketing was actually misleading. As Reuters reported, the appeals court panel — made up of circuit judges Ronald Gould, Jay Bybee and Daniel Bress — said plaintiffs could not show that every class member had actually seen the allegedly false statement on Tesla's website. Tesla had urged the court to vacate orders certifying three sets of classes that a California judge approved the prior year, and the panel agreed the class-wide approach could not stand.
At the center of the dispute is a claim plaintiffs say appeared on Tesla's website covering vehicles sold from October 2016 onward: that the cars contained the hardware needed for full self-driving capability. U.S. District Judge Rita Lin had ruled that thousands of prospective buyers were likely exposed to that statement, a finding that formed the basis for certifying the class before the appeals court stepped in. Plaintiffs allege Tesla misrepresented vehicle hardware capabilities for Full Self-Driving and induced customers to pay extra for software they say does not work as promised, while Tesla has denied the claims. Tesla did not immediately respond to Reuters' request for comment on the ruling.
A Years-Long Legal Battle Narrows
The underlying case, known as In re Tesla Advanced Driver Assistance Systems Litigation, dates back to September 2022, when lead plaintiff Thomas LoSavio and other owners filed suit in the Northern District of California accusing Tesla of deceptive marketing, according to OpenClassActions. The pool of eligible plaintiffs was already narrow by the time Judge Lin certified the classes in August 2025. A year earlier, in September 2023, federal judge Haywood Gilliam had sent the majority of the original named plaintiffs into individual arbitration because they had signed Tesla's standard purchase agreement, leaving only buyers who explicitly opted out eligible for court proceedings.
When Lin's certification order did come down, it covered California drivers who bought or leased a Tesla and paid separately for Full Self-Driving, with one pre-arbitration class covering October 20, 2016, through May 19, 2017, and a second class covering May 19, 2017, through July 31, 2024, limited to arbitration opt-outs, according to the Ted Law Firm. The appeal centered on the hardware statement's role in Tesla's marketing campaign.
Regulators Press Tesla on the Same Marketing Terms
While Tesla fended off the class action in federal court, state and international regulators have been scrutinizing the exact same branding. The California Department of Motor Vehicles issued an administrative decision in December 2025 finding that Tesla violated state false-advertising laws by using the terms Autopilot and Full Self-Driving Capability to market advanced driver assistance systems, according to the California DMV. The agency gave Tesla 60 days to resolve the issue or risk a dealer license suspension.
Tesla made temporary marketing adjustments to preserve its California dealer license, then filed its own lawsuit against the DMV in February 2026 seeking to overturn the false-advertising decision, arguing the ruling was factually incorrect, per Electrek. The pressure has not stayed domestic. Tesla agreed to rebrand its software to Tesla Assisted Driving on its European websites after German transportation authorities objected to the Full Self-Driving name, Electrek also reported.
Pricing Swings and Safety Probes Loom Over the Case
Electrek's pricing coverage listed an $8,000 one-time purchase option for Full Self-Driving.
The marketing dispute also sits alongside separate federal safety scrutiny of the technology itself. The National Highway Traffic Safety Administration launched a safety investigation in October 2024 into Full Self-Driving covering 2.4 million vehicles after four reported crashes in reduced-visibility conditions, including a fatal pedestrian collision, PBS News reported. Months earlier, in April 2024, regulators had opened a recall query into 2 million Teslas after finding that crashes continued even after a December 2023 over-the-air update meant to strengthen driver-attentiveness warnings, with investigators noting 20 new crashes following that initial fix, according to The Washington Post.
Individual tort cases have already produced costly results for Tesla even as the class action collapses. Hoodline reported in February that a federal judge sustained a $243 million jury verdict against the automaker in a fatal Autopilot crash in the Florida Keys, rejecting Tesla's request for a new trial after jurors assigned roughly one-third of the fault to the company. For now, Friday's 9th Circuit ruling addresses only class-action certification, not the merits of the plaintiffs' false-advertising allegations, meaning the broader question of whether Tesla's Full Self-Driving marketing was truthful remains unresolved in court.
