We have had a lot of heavy rain here lately and I have water holding in my liftgate. I heard it sloshing around when I would make a tight turn. When I lifted up the liftgate water started pouring from several locations, right into the rear cabin floor.. Has anyone had this problem? If so what did you do. Mine is a 2017 EX with 39000 miles on it so I guess it is out of warranty.. I am a little pissed.
