I just got a text from my dealership saying my oil light was on. Super pissed off about it… When I got the Jeep 2 years ago I asked Jeep to turn off ALL remote access/phone home capabilities to the vehicle. I was on the phone for a couple hours with them until I finally got someone who said they did it.

Weather alerts, contextual ads on my console, distant recording of my travels, whatever, I wanted everything off.

It has a 4G cellular module in the head unit, which connects to a separate 4G antenna via a port on the back of the head unit. Unplug the antenna from the head unit and it cannot communicate to anything. Obviously you have to remove a bunch of trim and the unit.
