Same thing happened to mine! I tried opening and closening it multiple times. I finally gave up and made an appt with the dealer. Well in between that appt was my appt withthe tint shop. When I picked my car up
My hood was flush again. The tint shop said they didnt do anything to it...just openend it and shut it. I reopened the hood and shut it myself and the hood stayed flush. Lesson to be learned here is just make an appt and the issue will resolve itself. Same happened with my squeaky brakes...that seemed to disappear on its own as well. Goodluck.
