Seoul Police Book 80 Tesla Drivers for Illegal FSD Unlock Devices, Seize 21 Units

South Korean authorities have taken their largest enforcement action yet against aftermarket devices that illegally enable Tesla's Full Self-Driving (FSD) feature in vehicles not permitted to use it in the country. The Seoul Metropolitan Police Agency announced on Tuesday that 80 individuals have been booked for using the unauthorized hardware, and 21 devices were seized. The crackdown targets a growing black market for FSD 'jailbreak' tools that have spread across China, Europe, and Korea over the past year. These devices bypass Tesla's regional restrictions, allowing drivers to activate advanced driver-assistance features without proper regulatory approval or safety validation. The police action underscores the legal and safety risks of modifying vehicle software, as unapproved FSD activation can lead to unpredictable behavior on public roads. Tesla has not commented on the Seoul case, but the company has previously warned that unauthorized modifications void warranties and may compromise vehicle safety systems. As autonomous driving technology advances, regulators worldwide are stepping up enforcement against unlicensed modifications, signaling a tougher stance on consumer-installed software hacks. The Seoul operation may serve as a template for other nations grappling with similar gray-market devices.
