Tesla has begun disabling Full Self-Driving (FSD) for owners using third-party devices to bypass regional restrictions. Reports of this are coming from Europe, China, South Korea, and other countries. Owners were installing CAN bus modules to activate FSD where the function is not officially available.
The cost of such devices is about 500 euros. After connection, the system "deceives" the car, making it think that it is in a region with available FSD.
However, Tesla has begun to identify such interventions. Owners receive a notification: "Your car has detected an unauthorized third-party device. As a precaution, some driver assistance features have been disabled for safety reasons."
In some cases, the company completely disables FSD, returning cars to basic autopilot. This is due to safety risks and interference with electronic systems.
Additionally, there are legal consequences. In South Korea, such modifications are considered illegal. Violators may face up to two years in prison or a fine of about $13,000.
The situation is developing against the backdrop of a possible early approval of FSD in Europe. According to sources, a decision by regulators could be made as early as April 2026.
