Has anyone experienced a case where they needed an over-the-air safety update/recall performed, but weren't able to because they removed the cellular modem?

I'd like to think failure to apply an OTA safety update would trigger a mail-out notification requesting you bring the vehicle into the dealer. But that's probably optimistic...

What type of fucking "safety" update could be performed?

If the car has a recall or safety issue with the suspension part failing prematurely, what possibly could some software nonsense do?

I think Chrysler does it too, but I only find mention of the time they bricked a bunch of Wranglers with a bad OTA update.

Broadly I don't think it's hard to imagine a software update being safety critical if the software is used in a safety critical system.

Its probably an antipattern on a car to need an OTA "safety" update in the first place.

The safety update is physically removing the modem IMO. Can't be wirelessly broken into if you aren't on the network to begin with.
