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)
One of the many reasons I always run privacy.sexy every time I need to install windows (on both bare metal and inside a VM).
