Hi all, looking for some help from someone who may have had a similar issue. Every time it rains I am getting water accumulation on the front passenger floorboard both on and under the floor mat. I put down some plastic and can tell its coming from dash/ floorboard area, NOT the door or the A/C. Anybody had a similar issue? I've checked several times myself and dealer has had the vehicle 4 times already and can not find an issue. I park on a slight elevation with the front end higher than the rear. Any thoughts or similar experiences/ fixes would be greatly appreciated.

Vehicle is 2020 Expedition

I believe somebody else had a similar issue and it turned out that Ford left some plugs out. I think the discussion was about a year ago.

I'm dealing with the same thing right now. So I'll be following to see what your outcome is. I have smart liners in and when I took mine out to clean the other day I noticed it was wet. I cleaned my carpets and let dry. When I checked again today it had the same condensation on the bottom side of my mat. I'm gonna take it to dealership and show them.
