My car is older than that and came with an embedded SIM card. Quite a few navigation consoles had "live traffic updates" (often in trial format, but sometimes "lifetime") that basically consisted of 2G clients occasionally updating traffic data along planned routes. Not quite bottom of the line at the time, but also not uncommon at that point either. It's probably slightly worse than the dedicated satnav screens people were buying back when the car was new, although neither compares to what a smartphone will expose passively from just being inside of a moving car.

Most people don't know, and will never know whether their car is connected to the internet, so it's better to assume it is unless you have specific information. The app or phone you connect to the car could also be a major exfil point of this data.
