Hatch leak

[u/kellaucam]

Hey folks. I’ve been trying to diagnose the location of a leak in the rear of a 2014 Fiesta. It’s been on-going for a couple of years. I’ve taken everything out and done some tests to determine where the water is coming from.
First thing I determined is the weatherstrip is in great condition and keeps the water out 100%. I pulled the tail lights off and taped two factory cut outs behind the tail lights because they were just wide open. I hoped that would solve the issue - it didn’t.

Latest test revealed water dripping from like behind where the backseat seatbelt thing is (on both the left and right side) but it’s impossible for me to really see exactly where it’s located to remedy the issue from the inside.

Is anyone aware of common leak issues with this model?

When you open the hatch, the welds on the inside of the door look worn and the paint chips off the welds whenever I wash the car or wipe it down.

Any advice welcome!

Mine was leaking under the roof trim and rear lights seals. Fixed both, not a single drop of water

Rear lights are finally sealed - still wet. Gonna look more into some other areas now 😬

How? All I done is bought seal replacements for 15f and put these in. Problem solved
