I've had occasions where I really thought I had left my car unlocked, say after bringing in groceries. But when I get back to my vehicle (2015 Dodge Journey) I sometimes find it already locked.
If the fob is outside the vehicle, and the car is left alone with the doors closed for some time, does it automatically lock?
I would greatly appreciate answers with an official source (an owner's manual, a spec sheet from Dodge, or something similar,) not personal experience.
