2015 F150 Platinum

 

my 2017 Platinum was collecting water mostly near the A pillar at the carpet. I have a sunroof. It had a crimped drain tube on that side from the factory. Dealer pulled the molding and replaced the drain tube. Carpet dried out and hasn't leaked again.

Friend has a 2016 Platinum with same issue. They roof rail indentation was leaking at the seam on the passenger side. He got some color coded seal/caulk and ran a bead all along the seam. Problem solved.

This is a problem with all the current trucks. There's these little drain holes at the bottom of the doors that get plugged up and you have to clean them. Kind of lame, but an easy fix. Both my rear doors do it occasionally.
