Many high-end cars have embedded cellular connections, in 2015 Miller and Valasek managed to crack into Jeep's, jump the airgap and take control of the car over the OTA reporting connection: https://www.wired.com/2015/07/hackers-remotely-kill-jeep-hig...

No idea if that's the case with Toyota, but it's definitely possible with some high-end cars (most definitely including Teslas which routinely report to the mothership) (incidentally it's fun seeing people drool over teslas then freak out at Firefox or MS telemetry)

Amusingly, the air-gap was a firewall on a chip. No air whatsoever. They got around it a few ways, including most effectively, by re-flashing it to just be a passthrough.

Based on that, I'd say anyone who is injured because of this in any way has a great claim against the company for lying about the equipment they provided.

I'm receiving the communication about 2-3 months ahead of that schedule due to the excess mileage I'm driving. At about 6k miles, my tire sensor was going on and off for a few days, then I received an email specifically to come in to check the tire pressure. It may have be coincidence, but it's highly unlikely at this point.
