I've got 8500 miles on my 19' and every time it rains or last winter when we got heavy wet snow I will get in my truck to find the floor mat soaked and water peeing out of the vent right above the drivers seat.
The last couple times it is running out the pillar and down the dash.
I've taken the truck into the dealer twice the first time for recalls one of which was apparently to check for sunroof seal/leaking.
The second visit was for the leak problem still happening and of course they found no issues.
I've got pictures showing the water pissing out and the water soaked headliner.
Any other 5th Gen owners having this issue?
