On an especially hot day, my ex's Civic touchscreen failed to boot, blocking her from using her AC, using her cameras or having full visibilty (the windows are so minuscule, it's like being in a submarine), being able to make or receive calls hands-free, or controlling her radio.
The firmware being outdated wouldn't be more of an issue than with any other head unit if they weren't internet connectable on top of being so integrated. I'm afraid someone has hard coded some service SSID to autoconnect to, and once the signing keys are cracked, that's all someone would have to do to push a compromised update.
I've made it a point never to own a vehicle that can accept OTA updates or that has always-on connectivity.
