Not normal. Look at the rubber seal on the bottom of the door to see if it is out of position. There are holes in the door frame that it snaps into. If nothing looks out of place, take it to the dealer.
Just curious if anyone else has experienced this issue. We had heavy rains on Friday night and Saturday morning when I went out to put in my new Weathertech's I opened the rear passenger door and water spilled out of the bottom. The rear drivers door had a bit of water in the door frame also but not as much. I'm definitely going to call the dealer about this just seeing if anyone had the same problem and if there was any issues with dealers getting it fixed.
