Edit: Just asked because of curiosity. I’m not actually looking for such vehicles.
Edit 2: So for context, my parents new Toyota has this feature that allows the GPS location of the car to be sent to toyota, then you can see the location via an app on android/ios (it’s supposed to be an anti-theft feature). The data is sent via an antenna that connects to cell towers, which then connects to the internet, and to the toyota servers. “Diagnostic” and “maintenance” information is also sent via those same antennas.
The dealer said it could be turned off, but who knows if they are really off. There’s not a hard switch on the car.
General Motors isn’t much better. (This is from 2011) " OnStar, the service started by General Motors to support drivers through a cell phone system in their cars, has now told customers it may collect information on their movements and driving habits – even if they no longer subscribe to the service." And “Unless the Data Connection in your Vehicle is deactivated, information about your Vehicle may continue to be collected even if you do not have a Plan.” https://abcnews.go.com/Technology/onstar-gm-privacy-terms-company-record-car-information/story?id=14581571

I didn’t imagine they were.
I’d feel it’s safe to assume any vehicle with the ability to send or receive data is going to be violating your privacy.
