Don't know what they are called exactly, the inside plastic cover for the side view mirrors are made in a way that they have a pointing edge at the top which apparently will tear the weatherstrip. Its the same on both driver & passenger doors, but the marks are now more apparent on the passenger side. See attached images, hope they are clear.
Was wondering if it is a design thing on all Edges/MKX or something is missing or misfit in my car.
