Agreed. My old i3 used to drop its window a little way when you opened the door so that internal pressure didn't make it harder to shut the door. Then the window went back up once the door was closed. I tried shutting the door on our MG4 with the window slightly open and it took less of a push. My wife quite often only half shuts the door on the car!Yes I get that. But it is not untypical for a new car to need to overcome the internal pressure to close properly.
It is not a defect.
