In the Leaf, you can disconnect the TCU from the CAN gateway controller located behind the infotainment system to disable its remote connections.

It will throw a perpetual "check engine" light and disable the hands-free microphone, but OVMS users have made a "dummy TCU" that gets around that annoyance.

I have the opposite problem. The specific infotainment system update I need requires a $200 visit to a dealership with a specific model of a USB 2.0 SanDisk Flash Drive (NI-52727-1). Not available OTA despite the Leaf's OTA capabilities.

In my country that car would then fail inspection immediately. Of course you could reattach before the check up, but then there is no excuse for just shutting it off.

Buying a modern car seems to come with too many strings attached these days.
