Most any vehicle with "telematics" available made in the last ~10 years is calling home with your location and a variety of information like cabin and outdoor air temperature, whether the wipers and headlights are on, etc. The data is sold to third parties, with varying levels of anonymization. This happens regardless of whether you're paying for a subscription to their telematics, whether you have a GPS navigation system optioned, etc.

I know this because a friend worked for a company trying to monetize that data for weather forecasting.

If you want to disable this nonsense, just unplug the cellular antenna and connect it to a dummy load.
