US appeals court dismantles Tesla FSD class action

A federal appeals court has dismantled the class action accusing Tesla of false advertising over Full Self-Driving, ruling that thousands of California buyers cannot sue jointly because no one can show they all saw the same misleading claim. A three-judge panel of the Ninth Circuit on Oct. 16 vacated the class certification and sent the case back to the district court, where each customer must now prove deception individually.

The plaintiffs, led by Thomas LoSavio, argue Tesla misrepresented its vehicles' FSD capabilities — specifically the claim, posted on the company's website from October 2016 to August 2024, that its cars already carried the hardware needed for full autonomy. Buyers paid extra for software they say does not work as promised. In August 2025, U.S. District Judge Rita Lin in San Francisco certified the class, reasoning that Tesla's direct-to-consumer model — product information funneled through the website and Elon Musk's public statements, rather than dealer networks — made it likely that FSD buyers had seen the hardware claim.

The appeals panel rejected that inference. For a consumer class to proceed, buyers must show they were all exposed to the same allegedly false statements in essentially the same way. The judges noted that product labels qualify because 'every purchaser necessarily has the allegedly misleading statement in front of him' — but there was, in the district court's own words, 'no specific requirement forcing [FSD purchasers] through the Autopilot page to complete their purchase.' Assumed exposure is not exposure.

The ruling does not touch the merits of the deception claim. What it changes is the economics of litigating it. A class action converts thousands of grievances into one trial with shared costs; decertification converts them back into thousands of separate suits, each too small to justify the lawyers a case against Tesla requires. A defendant with deep cash reserves and a direct sales channel built to bypass dealers now also gets to bypass aggregated plaintiffs. Plaintiffs' attorneys said the panel 'did not fully appreciate the unique circumstances here.' Tesla did not respond to a request for comment.

The product at issue still carries a name — Full Self-Driving — describing a capability it does not deliver, with liability that remains seated in a human driver. The court left that question open. It only decided who can afford to ask it.
