Ninth Circuit Vacates Class Certification in Tesla Full Self-Driving False Advertising Lawsuit, What the October 2026 Ruling Means for Owners

Quick Facts: Why Did the Ninth Circuit Vacate Class Certification in LoSavio v. Tesla?

On October 16, 2026, a three-judge panel of the U.S. Court of Appeals for the Ninth Circuit vacated a California federal judge’s order that had certified classes of Tesla customers who paid for Full Self-Driving (FSD). The panel held that the district court wrongly assumed every proposed class member had seen Tesla’s allegedly misleading statement about the hardware in their vehicles.

This is a procedural win for Tesla, but it is not a ruling that Tesla’s advertising was truthful. The court decided whether consumers could sue together as a class, not whether Tesla violated California law. The panel vacated two damages classes under Federal Rule of Civil Procedure 23(b)(3) and a related injunctive-relief class under Rule 23(b)(2), and sent the case back to the district court.

The decision is an unpublished memorandum, so it is generally nonprecedential under Ninth Circuit Rule 36-3. Read the Ninth Circuit memorandum.

What Is the Current Procedural Posture of the Tesla Full Self-Driving Lawsuit?

Here is where the case stands as of October 17, 2026:

• No class is currently certified. The classes Judge Lin certified in August 2025 were vacated. The case is now best described as a putative class action, meaning plaintiffs may still try to certify a class but none exists today.
• The case was not dismissed. The Ninth Circuit remanded it to the Northern District of California for further proceedings before Judge Lin.
• No confirmed further appeal. The memorandum does not show that rehearing or Supreme Court review has been sought. Under Federal Rule of Appellate Procedure 40, a petition for panel rehearing or rehearing en banc is generally due 14 days after judgment, which would be about October 30, 2026, absent an extension. Once the appeal ends, the court of appeals issues its mandate under Federal Rule of Appellate Procedure 41, and the district court proceeds from there.
• The merits are undecided. No court has ruled on whether the hardware statement was false, misleading or actionable.
• No money is being distributed. There is no settlement, refund program or claim deadline.

How Did Tesla Get to the Ninth Circuit Under Federal Rule of Civil Procedure 23(f)?

Rule 23(f) lets a court of appeals accept an interlocutory appeal from an order granting or denying class certification, at its discretion. Tesla used that route to challenge Judge Lin’s August 2025 order before any trial. That is why the Ninth Circuit could review certification while the underlying case was still pending.

What Did the Ninth Circuit Decide About Tesla’s Self-Driving Hardware Statement?

Judge Lin had inferred that Tesla’s direct-sales model, its reliance on its website and the importance of its Autopilot information made it highly likely that customers buying an expensive FSD package would see the relevant web page. The Ninth Circuit found that inference insufficient. Buyers did not have to visit the Autopilot page to complete a purchase, and the evidence did not show every proposed class member saw the disputed statement. Without that showing, the plaintiffs had not met the predominance requirement for the damages classes. Because the injunctive-relief class was tied to the damages classes, it fell too.

Why Did Classwide Exposure Matter in the Tesla Case?

Plaintiffs’ California claims depend on proof of material misrepresentation and, depending on the claim, reliance, causation or harm. Under Rule 23(b)(3), common questions must predominate over individual ones. If buyers saw different advertising or made purchases without encountering the statement, proving their claims could require individual evidence.

The panel contrasted this with a misleading product label that every buyer necessarily sees. An optional web page is different, because customers could complete their purchases without visiting it. The court also found that general website-traffic data and similar statements elsewhere did not prove every class member saw the hardware claim. The ruling turns on the evidence in this record and does not say website advertising can never support classwide exposure.

What Federal Class-Action Law Governed the Tesla Class Certification?

Federal Rule of Civil Procedure 23(a), 23(b)(3) and 23(b)(2)

A class must first satisfy Rule 23(a): numerosity, commonality, typicality and adequacy of representation. A damages class must then satisfy Rule 23(b)(3), which requires that common questions predominate and that a class action is superior to other methods of resolving the dispute. An injunctive-relief class under Rule 23(b)(2) requires that the defendant acted on grounds that apply generally to the class. Official rule: Federal Rule of Civil Procedure 23.

Rule 23(c)(1)(C): Can a Class Be Certified Again?

Rule 23(c)(1)(C) allows a certification order to be altered or amended before final judgment. That gives plaintiffs a possible route to ask Judge Lin to certify a new or narrower class, but they would have to cure the exposure problem the Ninth Circuit identified. The October 16 ruling does not guarantee any new class.

Supreme Court and Ninth Circuit Class-Certification Cases

Several well-known decisions frame this area of law. They help explain the standards involved, but the Ninth Circuit’s memorandum does not need to be read as relying on every one of them.

• Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338 (2011): plaintiffs must affirmatively prove Rule 23 requirements with evidence, not mere pleading.
• Comcast Corp. v. Behrend, 569 U.S. 27 (2013): a damages model must match the plaintiffs’ theory of liability for a Rule 23(b)(3) class.
• Mazza v. American Honda Motor Co., 666 F.3d 581 (9th Cir. 2012): reliance can be presumed classwide only when a material misrepresentation was made to the entire class, which is why exposure is central in consumer-advertising cases.
• Stearns v. Ticketmaster Corp., 655 F.3d 1013 (9th Cir. 2011): in a CLRA claim, a presumption of reliance may arise when a material misrepresentation was made to the whole class.

Which California Laws Were at the Center of the Tesla Full Self-Driving Lawsuit?

California Unfair Competition Law, Business and Professions Code § 17200

The Unfair Competition Law prohibits unlawful, unfair or fraudulent business acts and misleading advertising. Remedies are mainly restitution and injunctive relief, and the plaintiff must have suffered economic injury as a result of the practice (§ 17204). In In re Tobacco II Cases, 46 Cal. 4th 298 (2009), the California Supreme Court held that reliance is required only of the named plaintiffs, not absent class members. The limitation period is generally four years (§ 17208). Official law: Business and Professions Code § 17200.

California False Advertising Law, Business and Professions Code § 17500

Section 17500 prohibits untrue or misleading statements made in advertising goods or services. The plaintiffs alleged that Tesla’s statements about the hardware needed for self-driving capability were misleading. The Ninth Circuit did not decide that issue. Official law: Business and Professions Code § 17500.

Consumers Legal Remedies Act, Civil Code § 1770

The CLRA prohibits specified unfair or deceptive practices in consumer transactions. Remedies are in Civil Code § 1780, and the limitation period is generally three years under § 1783. A CLRA damages claim also requires a pre-suit notice letter under § 1782. Official law: Civil Code § 1770.

Fraud and Negligent Misrepresentation Under California Law

The complaint also pleaded common-law fraud and negligent misrepresentation. Fraud requires a misrepresentation, knowledge of falsity, intent to induce reliance, justifiable reliance and resulting harm. Negligent misrepresentation requires a false statement made without reasonable grounds for believing it true. The court dismissed the warranty claims earlier, while certain fraud-based, negligence-based and statutory claims tied to the hardware and cross-country statements were allowed to proceed. The Ninth Circuit did not decide their merits.

What Did Tesla Say About Full Self-Driving Hardware and Cross-Country Driving?

What Was Tesla’s October 2016 Hardware Statement?

In October 2016, Tesla and its CEO Elon Musk described the company’s then-new autonomous-driving hardware as sufficient for Level 5 autonomy. The district court’s certification order identified statements on Tesla’s Autopilot web page, and at times on model pages, that all vehicles built at its factory had the hardware needed for full self-driving capability. Similar claims appeared in a blog post and a newsletter.

The plaintiff points to later changes, including Hardware 3 and Hardware 4, and to Musk’s 2024 statement that some customers with Hardware 3 computers might need upgrades. Whether the earlier statements were accurate when made is not something the Ninth Circuit decided.

What Did Tesla Say About a Coast-to-Coast Autonomous Drive?

At a 2016 press conference, Musk described a goal of showing a fully autonomous drive from Los Angeles to New York by the end of the following year. The district court did not find enough evidence of classwide exposure to the cross-country statements, and the Ninth Circuit’s decisive analysis focused on the hardware statement.

Which Tesla Owners Were in the Vacated Classes?

Judge Lin’s August 2025 order covered limited California-connected groups, not every Tesla owner:

Previously certified class	General definition
California Pre-Arbitration Class	People who bought or leased a Tesla and separately paid for or subscribed to FSD between October 20, 2016 and May 19, 2017, who bought or leased in California or currently lived there.
California Arbitration Opt-Out Class	People who bought or leased a Tesla and separately paid for or subscribed to FSD between May 19, 2017 and July 31, 2024, who bought or leased in California or currently lived there, and who opted out of Tesla’s arbitration agreement.

A related Rule 23(b)(2) class sought injunctive relief. Enhanced Autopilot-only buyers were excluded. These definitions describe classes that no longer have certified status after October 16, 2026. Do not present them as active classes entitled to classwide relief. Source: Judge Lin’s August 18, 2025 order.

Does the Ninth Circuit Ruling Mean Tesla Did Not Mislead Consumers?

No. The panel did not decide whether the hardware statement was accurate, whether customers were misled, whether Tesla acted with fraudulent intent or whether any buyer suffered compensable loss. A court can find that a class is not the right procedural vehicle without deciding whether the underlying conduct was lawful. The allegations remain allegations unless proven in further proceedings or resolved by a valid agreement.

Tesla denies the claims. Reuters reported that Tesla did not immediately comment, and that the plaintiffs’ lawyers said they believed the panel had not fully appreciated the hardware statement’s role in Tesla’s marketing. Reuters’ report.

What Does the Ruling Mean for Tesla Owners Who Paid for FSD?

• No automatic refund. The court ordered no refund or damages.
• No active certified class. Owners cannot rely on the August 2025 certification as proof they belong to a current class.
• No settlement or claim portal. Do not send information to anyone claiming to run a Tesla FSD class settlement based on this ruling.
• Individual claims may still be possible, depending on the facts, applicable law and defenses.

Owners who believe they were misled should keep their purchase agreement, FSD purchase or subscription records, vehicle configuration details and any advertising or communications they personally saw.

Can Tesla Owners Still Sue Tesla Individually Over Full Self-Driving Advertising?

Possibly. A buyer who can show they personally saw the hardware statement before buying may have evidence the class lacked. That does not mean the claim will succeed. Issues an individual claimant would face include:

• Arbitration. Tesla’s arbitration agreement, which the Federal Arbitration Act (9 U.S.C. § 2) makes generally enforceable, may require individual arbitration instead of court.
• Limitation periods. UCL claims generally have four years, CLRA claims three years, and fraud claims generally three years under California Code of Civil Procedure § 338(d).
• CLRA notice. The § 1782 pre-suit notice requirement applies to damages claims.
• Proof. The claimant must still prove falsity, reliance, causation, injury and damages for the theory pleaded.

How Is the Ninth Circuit Ruling Different From the California DMV Action Against Tesla?

In December 2025, the California Department of Motor Vehicles adopted an administrative decision concluding that Tesla’s use of “Autopilot” and “Full Self-Driving Capability” in specified marketing was misleading under California law. The DMV acts under its licensing authority, including the Vehicle Code provisions on false advertising by licensed dealers and manufacturers (Vehicle Code § 11713). In February 2026, the DMV said Tesla had made corrections, including using “Full Self-Driving (Supervised)” and ending the misleading use of “Autopilot” in California marketing, which let Tesla avoid a 30-day license suspension. California DMV announcement.

That proceeding is separate from LoSavio. The Ninth Circuit did not review it, and it does not automatically establish that the specific hardware statements in this lawsuit were false.

Is Tesla’s Current Full Self-Driving System Fully Autonomous?

Tesla’s current U.S. support page describes the product as Full Self-Driving (Supervised) and says active driver supervision is required and that the features do not make the vehicle fully autonomous. Tesla’s FSD (Supervised) information.

The lawsuit discusses hardware “capable of Level 5 autonomy,” the industry term for full driving automation without a human required to drive. A system that needs an attentive human ready to take over is not driverless operation. This background does not decide the legal question, and the Ninth Circuit did not rule on the capabilities of Tesla’s current system.

What Happens Next in the Tesla Full Self-Driving Lawsuit?

The next confirmed stage is further proceedings in the Northern District of California before Judge Rita F. Lin. Possible developments include a rehearing petition, a motion to certify a revised class under Rule 23(c)(1)(C), and decisions on how the remaining claims proceed individually. The panel did not decide whether the plaintiffs’ damages model was otherwise adequate, since the exposure issue was dispositive. Nothing in the order guarantees another class will be certified.

Frequently Asked Questions About the Ninth Circuit’s Tesla Full Self-Driving Ruling

Did the Ninth Circuit dismiss the Tesla Full Self-Driving lawsuit?

No. It vacated the class-certification order and remanded for further proceedings. It did not decide the merits.

Why did the Ninth Circuit vacate the Tesla FSD classes?

The district court inferred that all proposed class members saw Tesla’s hardware statement, and the evidence did not support that inference. Without classwide exposure, the plaintiffs did not satisfy predominance for the damages classes.

Did the court find Tesla’s FSD advertising was truthful?

No. It ruled only on class-certification requirements.

Who was covered by the vacated Tesla classes?

California-connected buyers or lessees who separately paid for FSD between October 20, 2016 and July 31, 2024, with the later group limited to those who opted out of Tesla’s arbitration agreement. Those classes are no longer certified.

Can Tesla owners still sue individually over FSD?

Possibly, subject to arbitration, limitation periods and proof of the elements of their claims.

Is there a Tesla FSD refund or settlement because of this ruling?

No. The ruling creates no settlement, refund program, claim portal or payment deadline.

Does the Ninth Circuit ruling affect the California DMV’s Tesla case?

No. The DMV decision is a separate administrative matter, and the appeal concerned private consumer claims and class certification.

What did Thomas LoSavio buy from Tesla?

According to the certification order, he bought a Model S in early 2017 and paid separately for Enhanced Autopilot and FSD.

Did the court rule on the plaintiffs’ damages calculations?

No. The panel said exposure was dispositive and did not address the damages model.

Is the Ninth Circuit’s Tesla decision binding on other courts?

It is an unpublished memorandum, generally nonprecedential under Ninth Circuit Rule 36-3, except as that rule permits. It still controls the outcome of this appeal.

Can the plaintiffs ask for a new class in the Tesla case?

They may try under Rule 23(c)(1)(C), but they would have to cure the exposure problem the Ninth Circuit identified.

What is the next deadline for Tesla owners?

None arises from this ruling because it created no settlement or payment process. Future dates depend on the district court proceedings and any further review.

Conclusion: Tesla Wins Its Appeal on Class Certification, but the Full Self-Driving Claims Remain Unresolved

On October 16, 2026, the Ninth Circuit vacated class certification in LoSavio v. Tesla because the district court improperly inferred that the proposed class members saw Tesla’s allegedly misleading hardware statement. No class is currently certified, the case continues in the Northern District of California, and no court has decided whether Tesla’s statements were false. There is no refund or settlement program. Individual claims may remain possible, and any new attempt to certify a class would have to meet Rule 23 on the evidence.
