Tesla wins appeal: FSD buyers in California can no longer sue as a class over 'self-driving hardware' claims

Tesla has won an important procedural round in one of its longest-running legal fights over Full Self-Driving. On Thursday October 16, a three-judge panel of the US Court of Appeals for the Ninth Circuit reversed the decision that had allowed California FSD buyers to sue Tesla together as a class. The case is not over, but it has become much harder, and much smaller, for the people bringing it.

What the court decided

The case is LoSavio v. Tesla, filed in 2022. The plaintiffs say Tesla misled buyers by claiming that cars sold from October 2016 onward had all the hardware needed for full self-driving, a promise those cars still have not delivered on years later.

In August 2025, US District Judge Rita Lin in San Francisco certified three classes of California customers who had paid extra for the FSD package: two classes seeking money damages and one seeking an injunction. Tesla asked the Ninth Circuit for permission to appeal, and got it.

Judges Ronald Gould, Jay Bybee and Daniel Bress have now reversed all three certifications. The key points:

• The problem was exposure. The disputed hardware statement appeared on Tesla's Autopilot web page. Buyers did not have to visit that page to order a car or buy FSD, so the plaintiffs could not show that every member of the class had actually seen it.
• Individual questions win. Because the court would have to ask, buyer by buyer, what each person saw and when, the panel found that a single group trial was not appropriate. Website traffic data and other Tesla statements were not enough to bridge that gap.
• Timing matters too. When each customer saw the claim also affects whether their claim was filed in time, another issue that differs from person to person.

What the ruling does not say

It is important to be precise about what Tesla won. The appeals court did not decide whether Tesla's hardware statement was true or misleading. It ruled only on whether the case could go forward as a class action. The lawsuit itself is not dismissed and now goes back to Judge Lin.

The decision is also an unpublished memorandum. Under Ninth Circuit rules, that means it does not set a binding precedent for other cases, even if other judges may still find its reasoning persuasive.

The plaintiffs' lawyers said they believe the panel "did not fully appreciate the unique circumstances" of the case. Tesla has denied the allegations throughout.

Why it matters

Class actions are what make consumer cases like this dangerous for a company. One buyer who paid several thousand dollars for FSD has little reason to fight a long court battle alone, but tens of thousands of buyers grouped together can add up to a very large claim. Without class status, each owner has to bring their own case, and many Tesla buyers also signed purchase agreements that send disputes to private arbitration rather than court. In 2023, a judge already sent most of the original named plaintiffs in this case to individual arbitration for that reason.

For Tesla, the timing is helpful. The company is promoting FSD more heavily than ever, with most new cars in North America now sold with a paid FSD subscription, and it has told investors that unsupervised driving in customer cars could start around the second quarter of 2027. Older cars remain a sore point, though: vehicles with Hardware 3, sold for years as FSD-capable, are getting only a reduced "Lite" version of the latest software.

What to watch next

• A narrower class. The plaintiffs could try again with a smaller group, for example only buyers who can show they saw the hardware statement. There is no sign yet that they have done so.
• Individual claims. Owners can still pursue their own cases, in court or arbitration depending on their purchase contract.
• The Hardware 3 lawsuit. A separate class action filed in June 2026 targets Tesla's promises about FSD compatibility on older hardware. This ruling does not decide that case.

In short: a clear legal win for Tesla on procedure, but no verdict on the substance of what it told buyers about self-driving.
