Bought a 2018 2.5i Limited. Still getting used to the Subaru systems as this is my first. Had a strange thing with the back doors but I assume I just need to know how it works. Have the kids in the back in car seats and after driving to our destination my wife and I get out. When we go to the back doors they are locked. But our front doors were not when we stopped. Its not a child lock thing, I don't think, since that is about opening from the inside not the outside. Am I missing something where the back doors don't unlock when stopped?
