Seoul Court Defines the Scope of Tesla FSD | China-Built Vehicles, Overseas HW3 Litigation, and the Implications of Tesla at $403.3

1. Seoul Court Ruling on Tesla FSD Refund Claims

Why the Claims of 89 Tesla Owners Were Dismissed

A civil division of the Seoul Central District Court rejected claims seeking refunds of FSD option payments from Tesla Korea.

The plaintiffs reportedly purchased FSD between 2019 and 2022 for approximately KRW 6 million to KRW 9 million.

They argued that Tesla had failed to deliver functionality consistent with the Full Self-Driving name and that the HW3 computer was incapable of supporting the originally promised features.

They also viewed Tesla’s adoption of the term “FSD Supervised” and the introduction of subscriptions as a retreat from earlier representations regarding full autonomy.

Tesla Korea argued that substantial elements of the package had already been delivered, including basic Autopilot, automatic lane changes, parking assistance, and vehicle summoning.

It also maintained that contract cancellation would require restoration of benefits already used by consumers, making the software package materially different from a wholly undelivered product.

The Court Did Not Interpret FSD as Level 5 Autonomy

The court reportedly prioritized the contractual terms and purchase disclosures over the product name.

It interpreted FSD as a partially automated system requiring driver readiness and as a software package combining multiple driver-assistance functions.

The FSD name alone was therefore insufficient to establish a binding commitment to deliver Level 5 driverless operation.

Tesla’s website disclosures that regulatory approval could take substantial time in certain jurisdictions also appear to have influenced the decision.

The court found that purchasers were aware that some functions would not be available immediately and could be introduced incrementally.

Meaning of a Contract with an Indefinite Performance Date

The court reportedly treated the FSD agreement as a contract requiring future performance without a fixed completion date.

Accordingly, an extended delay alone did not automatically establish breach of contract or grounds for termination.

The court also recognized that delays caused by regulatory approval and domestic safety standards were not entirely within Tesla’s control.

If upheld on appeal, this interpretation could influence future disputes involving AI software and autonomous-driving options sold in South Korea.

2. The Central Issue: Contractual Performance for HW3

Must HW3 Owners Receive the Same Functions as HW4 Owners?

The most consequential element of the ruling was the conclusion that Tesla’s obligations to HW3 owners should be assessed against HW3’s technical capabilities rather than HW4 performance.

The court reportedly found that a failure to deliver functions identical to those available on newer HW4 vehicles did not, by itself, constitute breach of contract.

One factor was the deployment of a limited FSD Version 14 update to domestic HW3 vehicles.

The addition of traffic-light and road-sign recognition, along with limited urban driving assistance, was recognized as partial contractual performance.

The plaintiffs argued that delivering reduced functionality should not be sufficient to satisfy an agreement for full FSD.

The court nevertheless declined to conclude that every hardware generation sold under the same product name must provide identical performance.

Why the HW3 Finding Is Favorable to Tesla

• Tesla may face less pressure to replace all HW3 computers with HW4 hardware immediately.
• Software updates delivering functions within HW3’s capabilities may qualify as contractual performance.
• The risk of broad refunds or free hardware replacements for domestic FSD purchasers may decline.
• Differences in functionality between hardware generations do not automatically establish breach of contract.

HW3 Risk Has Not Disappeared

Contractual delivery of some functions is separate from the technical feasibility of unsupervised autonomous driving.

If statements by Elon Musk indicate that HW3 cannot support unsupervised FSD, overseas litigation may focus on the accuracy of prior advertising and sales representations.

Any higher-performance computer upgrade for HW3 owners would generate component, service-center labor, and supply-chain costs.

Investors should therefore monitor the number of eligible vehicles and the replacement cost per vehicle, not only litigation outcomes.

3. Does the Ruling Apply to China-Built Model 3 and Model Y Vehicles?

Why Domestic FSD Availability Remains Limited

Of approximately 180,000 Teslas registered in South Korea, only 4,292 vehicles, or about 2.4%, were identified as legally eligible to use FSD.

Vehicles manufactured in the United States may benefit from certification procedures under the Korea-U.S. Free Trade Agreement, while China-built Model 3 and Model Y vehicles may require separate domestic safety certification.

As a result, some owners of China-built Teslas have purchased FSD without being able to activate it.

The Key Difference Between Existing Plaintiffs and Owners of China-Built Vehicles

The plaintiffs in the current litigation reportedly received limited FSD updates and some driver-assistance functions.

Owners of China-built vehicles who cannot activate FSD at all may therefore present materially different facts regarding contractual performance.

The existing ruling could support the argument that regulatory delays are not solely Tesla’s responsibility.

However, separate issues include whether Tesla adequately disclosed certification uncertainty, the expected delivery schedule, and whether any paid functionality was made available.

Key Issues in Potential Litigation Involving China-Built Vehicles

• Whether Tesla specifically disclosed certification restrictions when selling FSD for China-built vehicles.
• Whether consumers knew that FSD could not be used on those vehicles at the time of purchase.
• Whether collecting advance payment was appropriate when regulatory approval remained uncertain.
• Whether a contract’s purpose can be considered fulfilled when no relevant functionality has been delivered.
• Whether Tesla clearly explained certification differences between U.S.-built and China-built vehicles.

The first-instance ruling does not eliminate the possibility of refunds for owners of China-built Model 3 and Model Y vehicles.

4. Investigation of 80 Owners Who Used Unauthorized Devices to Activate FSD

The Seoul Metropolitan Police Agency’s traffic crime investigation unit reportedly investigated approximately 80 owners who installed unauthorized devices to activate FSD.

Some devices were purchased from China or Europe, while others were reportedly assembled using publicly available online materials.

Similar devices were said to be available through overseas marketplaces for approximately $20.

South Korea’s Motor Vehicle Management Act restricts unauthorized modifications to automotive software and devices that may affect safe operation.

Violations may result in imprisonment of up to 2 years or a fine of up to KRW 20 million.

Liability may arise from bypassing safety systems even if no accident occurs.

Tesla can reportedly review vehicle software status and feature-activation records through its servers.

Removing a device or deleting local records may not prevent detection.

Unauthorized activation may also affect vehicle warranties, insurance coverage, and accident liability.

5. Overseas HW3 Class Actions and the Korean Ruling

Contractual Performance in South Korea Versus Advertising Accuracy Overseas

The Korean litigation focused on whether Tesla delivered enough of the purchased functionality to satisfy the contract.

Litigation in the United States and other jurisdictions may instead focus on whether advertising claims and management statements concerning FSD and HW3 were accurate.

HW3 owners have reportedly filed class actions in the United States, while consumers in Beijing, Australia, and the Netherlands are also pursuing compensation or accountability.

If Tesla relied primarily on HW4 vehicles during the European approval process, questions may arise over whether HW3 vehicles can ultimately receive comparable functionality.

Why the Korean Ruling Is Unlikely to Control Overseas Cases

• Consumer-protection and advertising laws differ by jurisdiction.
• Tesla’s sales language and disclosures may vary across markets.
• Purchase dates and vehicle hardware versions differ.
• The Korean case focused on cancellation and refunds, while overseas cases may emphasize misleading advertising.
• Regulatory approvals and delivered functionality vary by country.

The Korean first-instance ruling may support Tesla’s defense strategy, but it will not determine the outcome of overseas class actions.

6. European FSD Approval and the “Tesla Assisted Driving” Strategy

Tesla has reportedly begun using the term “Tesla Assisted Driving” in Europe instead of FSD.

The change appears intended to address regulatory concerns that the Full Self-Driving name could imply operation without a driver.

An Italian transport official was reported to support accelerated approval of Tesla’s driver-assistance technology, while Germany was also described as receptive.

France has maintained concerns regarding system safety and product terminology.

European Union approval may require thresholds based on both the number of member states and their share of the EU population.

The positions of large markets such as Germany, France, and Italy could therefore be decisive.

Approval would allow Tesla to expand software and subscription revenue across its installed vehicle base.

Continued delays or approval limited to HW4 vehicles could increase both HW3 customer dissatisfaction and upgrade costs.

7. U.S. Cybercab Regulation Is a Separate FSD Risk

The U.S. National Highway Traffic Safety Administration reportedly asked Tesla to explain how the Cybercab, which lacks a steering wheel and pedals, would comply with existing Federal Motor Vehicle Safety Standards.

If current rules assume a foot-operated brake pedal, Tesla may require an exemption or regulatory amendment before commercial sales can begin.

Submitting a response to a regulator is not equivalent to receiving sales approval.

Authorities may request additional documentation, testing, or safety measures.

Management’s Cybercab delivery targets should therefore be evaluated separately from the regulatory approval schedule.

Commercial deployment could extend Tesla’s business model from electric-vehicle sales to a robotaxi platform.

Before deployment, Tesla must address technical reliability, regulatory approval, insurance liability, and remote-operations costs.

8. Investment Considerations at a Tesla Share Price of $403.3

Tesla shares closed at $403.3, down 0.23% for the day.

With the Nasdaq declining 1.38% during the same session, Tesla demonstrated relative resilience.

However, one day of market outperformance does not eliminate legal risks surrounding FSD or valuation pressure from interest rates.

Potentially Favorable Factors for Shareholders

• The court did not interpret FSD as a definitive commitment to deliver Level 5 autonomy.
• The argument that HW3 vehicles must provide performance identical to HW4 vehicles was rejected.
• The near-term risk of broad domestic refunds for FSD options has declined.
• Software updates may qualify as contractual performance.

Risks Shareholders Should Not Underestimate

• The reported decision is a first-instance ruling and is not final.
• An appeal could result in a different legal interpretation.
• China-built vehicles without any FSD access present materially different facts.
• Overseas litigation may focus on misleading advertising rather than contractual performance.
• A broad HW3 replacement program could generate substantial one-time costs.

9. U.S. Economic Conditions and Tesla’s Valuation

U.S. third-quarter annualized GDP growth was reported at 3.4%, while personal consumption expenditure inflation was stated at 3.6% year over year.

Strong growth combined with elevated inflation could weaken expectations for Federal Reserve rate cuts.

Forecasts of additional rate increases would create further pressure on growth-stock sentiment.

Tesla’s valuation reflects substantial expectations for future cash flow and autonomous-driving revenue.

Higher interest rates reduce the present value of future earnings and may pressure Tesla’s valuation multiple.

Higher auto-loan rates also increase monthly payments for Model 3 and Model Y buyers, potentially affecting demand.

Oil prices were reported near $101 per barrel.

High oil prices may improve the relative operating-cost case for electric vehicles, but sales also depend on vehicle pricing, financing costs, charging infrastructure, and subsidies.

Quarterly deliveries and inventory levels remain more informative than oil prices alone.

10. Implications of AI Semiconductors and Memory Prices for Tesla

Intel reported higher data-center and AI-related revenue, but its shares declined after the subsequent quarterly outlook fell below market expectations.

The market continues to place greater weight on forward growth and profitability than on current AI-related revenue alone.

Amazon and Google are also making substantial capital investments in cloud and AI infrastructure.

AI revenue growth may be accompanied by even faster increases in spending on data centers, GPUs, memory, and power infrastructure.

Tesla faces similar cost dynamics.

FSD training and inference, data centers, Dojo, and Optimus development require significant semiconductor and memory capacity.

Higher memory prices could increase both vehicle-computer costs and AI training infrastructure expenditure.

Semiconductor availability and memory pricing may therefore affect vehicle costs, autonomous-driving development, and cash flow simultaneously.

11. Key Issues Often Overlooked

First, the Court Prioritized Contractual Terms and Disclosures Over the FSD Name

The “Full Self-Driving” name alone did not establish an obligation to deliver Level 5 autonomy.

In future AI product disputes, contractual terms, feature descriptions, and disclosed limitations may carry more legal weight than marketing terminology.

Second, HW3’s Technical Limitations Did Not Automatically Constitute Breach of Contract

If upheld, the ruling may allow Tesla to satisfy contractual obligations by delivering reduced functionality within HW3’s capabilities.

Consumers may nevertheless continue to challenge differences in functionality among vehicles sold with the same FSD package.

Third, Hardware Replacement Costs May Be More Material Than Refund Exposure

Even if Tesla prevails in litigation, replacing HW3 computers to support unsupervised operation could require substantial cash expenditure.

The key variables are the number of eligible vehicles and the replacement cost per vehicle.

Fourth, China-Built Vehicles Require Separate Analysis

HW3 owners who received limited functionality are not directly comparable to owners of China-built vehicles that have never been able to activate FSD.

The ruling should not be applied uniformly to every Tesla owner in South Korea.

Fifth, FSD’s Commercial Value May Depend More on Regulatory Timing Than Technical Demonstrations

Technology cannot generate broad revenue unless European approval, U.S. Cybercab regulation, and Korean vehicle certification are resolved.

Investors evaluating Tesla as an AI company should monitor the number of approved markets and paying users rather than relying primarily on demonstrations.

12. Key Events and Metrics to Monitor

• Whether the plaintiffs appeal the domestic FSD refund ruling and how higher courts respond.
• Progress toward domestic FSD certification for China-built Model 3 and Model Y vehicles.
• Tesla’s official HW3 upgrade process and allocation of related costs.
• European Union approval of Tesla’s driver-assistance system.
• Further NHTSA inquiries regarding Cybercab and potential regulatory amendments.
• FSD paid-user numbers, subscription conversion rates, and recognition of related deferred revenue.
• The impact of semiconductor and memory-price increases on Tesla’s capital expenditure.
• The effects of U.S. growth, inflation, and interest rates on electric-vehicle financing costs.

< Summary >

The Seoul court interpreted Tesla FSD as a software package with incrementally delivered driver-assistance functions, rather than a definitive commitment to Level 5 autonomy.

It also indicated that providing functions within HW3’s capabilities may satisfy the contract, even if HW3 does not match HW4 performance.

The first-instance ruling may reduce Tesla’s domestic refund exposure, but it does not directly resolve disputes involving China-built vehicles without FSD access or overseas HW3 class actions.

At a Tesla share price of $403.3, investors should assess litigation outcomes alongside HW3 replacement costs, European approvals, Cybercab regulation, interest rates, and AI infrastructure expenses.
