I haven't had any issue closing any of the doors with just normal pushes or pulls. I certainly haven't had to slam the door. I hate when doors require a lot of push to close. I certainly haven't noticed any door taking more work than another. The only thing we have a bit of a problem with is the seat levers in the back are a little stiff, but we have only had the car for 4 days now so I am guessing it is the newness of the car more than anything.
