Tesla remote FSD removal over third-party accessories: Difference between revisions

In early April 2026, Tesla began remotely disabling Full Self-Driving (FSD) and other driver-assistance functionality on vehicles whose telemetry indicated the presence of a third-party accessory connected to the Controller Area Network (CAN) bus.<ref name="electrek">Lambert, Fred (9 Apr 2026).

In a number of cases the revocation downgraded the vehicle's paid Full Self-Driving package to Enhanced Autopilot, removing not only the unofficially region unlocked FSD functionality but also Traffic Light and Stop Sign Control, a feature that is officially sold, regulator-approved in the affected markets, and was included in the FSD package the owner had paid for.
