This has already happened. Mostly to Russia

> In late 2025, hundreds of Porsche vehicles in Russia became "bricked" (immobilized) because the cars’ satellite-based security systems (VTS) required continuous connectivity to European servers. Following the suspension of Porsche's operations in Russia, the cars could not "phone home" and automatically activated anti-theft immobilizers, preventing engines from starting.

> Tesla has remotely disabled Full Self-Driving (FSD) capabilities on vehicles in multiple countries—including Europe, South Korea, China, and Turkey—after detecting unauthorized "jailbreak" devices used to enable FSD in regions where it was not authorized.

> Reports from July 2024 indicate that Chinese brands have planned to or have blocked multimedia systems and other features in cars that were imported into Russia through non-authorized channels rather than through official dealers.

> American manufacturer John Deere remotely disabled advanced agricultural equipment looted by Russian forces from Ukraine, rendering the high-tech machinery useless after it was moved to Chechnya.
