A South Korean court has ruled in favor of Tesla in a lawsuit brought by dozens of vehicle owners seeking refunds for its Full Self-Driving (FSD) driver-assistance package.
The Seoul Central District Court rejected the refund claims on October 29, 2026, finding that Tesla had not breached its contractual obligations. The plaintiffs argued that the company had failed to deliver the autonomous driving capabilities they expected when purchasing the option.
The ruling is a significant development in the debate over how automakers market advanced driver-assistance technology and what customers can reasonably expect from features branded as “Full Self-Driving.”
According to South Korean media reports, 89 Tesla owners were involved in the case. They had purchased vehicles equipped with the FSD option between 2019 and 2022 and filed their lawsuit in December 2024. Source: Yonhap News Agency
Why Tesla Owners Sought Refunds
The owners argued that Tesla had not delivered the promised driving capabilities despite years having passed since they purchased the FSD option. They asked the court to cancel their purchase contracts and order the company to return the money paid for the feature.
The dispute centers on the difference between advanced driver assistance and fully autonomous driving.
Although Tesla uses the name Full Self-Driving, its FSD system requires driver supervision. The plaintiffs argued that the functions available to them did not match what they had expected when paying for the option.
The case focused particularly on vehicles equipped with Tesla’s Hardware 3.0 computer, an older generation of onboard computing hardware used in some of the plaintiffs’ vehicles.
Why the Court Ruled in Tesla’s Favor
The court found that the FSD option purchased by the plaintiffs did not constitute a promise of Level 5 autonomous driving, in which a vehicle can operate without human intervention.
Judges noted that the owners had already received some functions included in the package, such as basic Autopilot and Enhanced Autopilot features. The court also considered additional functions made available through software updates, including traffic-light and road-sign recognition and city-driving capabilities for compatible vehicles.
The court further determined that the contractual obligation to provide additional features depended on technological development and regulatory approval. It found that the buyers had purchased the option knowing that some features might take considerable time to become available.
The ruling also addressed differences between the capabilities available on Hardware 3.0 and those offered on newer hardware. The court concluded that receiving a different version of the system from the one available on newer vehicles did not, by itself, mean Tesla had failed to perform its contract.
As a result, the court rejected the owners’ claims for refunds.
What the Ruling Means for Tesla’s FSD Technology
Tesla’s FSD package has become a prominent example of the challenges facing the autonomous-driving industry. Automakers are developing increasingly sophisticated systems, but technical limitations, local regulations and differences between vehicle hardware can affect which features are available in each market.
The South Korean ruling does not mean that Tesla’s vehicles can drive everywhere without human supervision. Nor does it establish that every possible dispute over FSD marketing or performance must be decided in Tesla’s favor.
Instead, the court assessed the specific purchase agreements, the features supplied to the plaintiffs and the conditions under which additional capabilities were to be delivered.
The distinction matters because the term “Full Self-Driving” can sound more comprehensive than the system’s actual capabilities. Drivers must follow the instructions for their vehicle and remain attentive and ready to intervene when required.
A Wider Debate Over Self-Driving Claims
Tesla faces broader scrutiny over the development and marketing of its autonomous-driving technology. Similar disagreements over delayed features and customer expectations have emerged in other markets.
The South Korean case illustrates the difficulty of resolving these disputes: buyers may expect a product to become more capable through future software updates, while manufacturers may argue that the timing of those updates depends on technology and regulatory approval.
For Tesla owners, the ruling means the plaintiffs will not receive the requested refunds through this first-instance judgment. The case also raises a wider question for the industry: how clearly should companies communicate the limits of driver-assistance systems when selling them as advanced or self-driving technology?
