ah crap. I don’t use all the “Uconnect” garbage on my 9 year old Jeep, but it does appear though the dealer can collect (read: steal) info if I bring it in (I do maintenance myself but I have brought it in for recall fixes before). As far as “smart” stuff goes, I do connect my phone via bluetooth but I run GrapheneOS on my mobile so hopefully this mitigates some stuff. I’ve always thought it was just cars with data connections and cameras/self-driving modules that were the problem (at least in my understanding of networking vis-a-vis my background in network development, but then again cars run different firmware)
So how do newer cars send this info back? Do they have their own transmitters? Or are they uploading data via my wifi while parked in my garage? If so, can I just block the vehicle’s MAC on my network?
If you have a car that uses cellular for in-car wifi or any other services (such as Onstar or competing services) that’s the way. And it’s possible (though I have no idea if it’s done) that they could include a cellular connection that isn’t available to you as the customer, but is used only for this purpose.
If you have any car with a modern suite of entertainment/nav/tech packages (which you personally do not I get that) you are a victim of this.

They have their own transmitters over cellular network.
