Anyone find the hinge pocket filled with water?
I opened the trunk after rain and found the depression where the hinge and piston mount filled with water.
To the rear it goes under a plastic cover above the tail light.
I cant imagine they would build a well where water builds up without a drain. So Im wondering if pollen or leaves clogged something.
It seems to me if the water cant escape from there it will overflow right into the trunk.
