A South Korean consumer advocacy group has filed a complaint with the country's Fair Trade Commission over Tesla's Full Self-Driving software, arguing that buyers have been charged for a feature many of them cannot switch on. The group, Citizens United for Consumer Sovereignty, says Tesla has collected payment for FSD for more than three years on vehicles that are ineligible to run it.
The complaint, reviewed by Reuters, centres on where each car was built. Only around 20% of Teslas registered in South Korea, the US-built cars, can enable FSD, because they meet US Federal Motor Vehicle Safety Standards and a trade agreement treats those standards as acceptable for Korean entry without further modification. The rest, mostly Shanghai-built cars, have no equivalent arrangement covering the software.
Why the country of manufacture decides FSD access
Tesla has imported roughly 170,000 China-built cars into South Korea since 2023, with that volume rising five-fold last year alone. Those vehicles account for the bulk of the fleet that cannot activate FSD today, and 99% of Teslas imported into Korea in 2025 were Chinese-built and ineligible for the feature.
The split matters because FSD availability in Korea is tied to a vehicle's import status rather than to the hardware or the price paid. Owners of the affected cars bought the same software option as US-built owners but have no way to use it in normal operation.
The money buyers have already spent
According to the complaint, buyers paid as much as $6,800 for FSD without being able to turn it on. Some resorted to a "jailbreak" that unlocked the region-locked software, a workaround regulators view as a safety circumvention and one that has left owners facing jail time or fines of up to $15,000.
That gap between what was paid for and what was delivered is the heart of the case. The complaint frames it as an advertising issue as much as a software one, questioning how Tesla presented FSD to Korean buyers while the feature remained unavailable on most of the cars it sold there.
A court has already sided with Tesla once
The new complaint follows a legal loss for owners. The Seoul Central District Court threw out a lawsuit from 88 owners who had sought full refunds in a case filed in 2024, ruling that Tesla had not breached its contractual obligations.
The court accepted that delivery of the features promised with FSD depended on technical advances and regulatory approval that buyers knew could take considerable time to arrive, and that Tesla was therefore not at fault when they did not.
That ruling makes the Fair Trade Commission route a different kind of test. The court looked at whether Tesla broke a contract; the regulator is being asked to look at how the feature was advertised and sold. The KFTC confirmed it opened a probe into Tesla's advertising earlier this year and declined to comment further, while Tesla did not respond to Reuters' request for comment.
The distinction is a meaningful one for owners. A contract claim can fail on the fine print of what buyers were told to expect, while an advertising complaint turns on the impression created at the point of sale. Whether the regulator acts after the court's ruling is not yet known.
A feature still waiting on its own name
FSD will turn ten years old next month. It has spent nearly four of those years labelled an official beta product and more than two under the "Full Self-Driving (Supervised)" rebranding, and a car in a driveway today still cannot technically drive itself without the person behind the wheel responsible for what happens.
For Korean buyers of the affected cars, the wait has an extra layer: the software is not merely supervised in their vehicles, it is unavailable. That makes the country a starker example of a tension running through FSD's decade, between what the option promises and what each market's rules allow it to do.
