as a professional diesel mechanic for a small chain of midwest shops, this "telematics" feature is on long-haul trucks as well as tractors (john deer is notorious for using it to send mail marketing about services.)

generally its not hard to disable.

- identify the telematics module in your car - pull the fuse (not always an option, sometimes this disables bluetooth)

- alternatively: identify the 1-2 SMC connectors on the telematics device. this is the LTE and low/alt channel for the cellular communications. disconnect these 1-2 connectors and connect the ports instead to a 50 ohm terminator. the vehicle will simply continue to collect data but never be able to send it anywhere. the system will assume it just cant find a tower.
