Definitely not a hard and fast rule for 2014, GM vehicles had On-Star in like 2004 I think, but they ran on 3g I think so most are inoperable now. I can't speak for ANY vehicles outside the US.

If your looking for a spyware free vehicle, you probably shouldn't consider anything newer. I believe most European countries have also mandated full "tracking" even always-on cameras. In the US they are requiring vehicles mad after 2025? (I think) to have in-car cameras capable of knowing if you are too impaired to drive and lock you out.
