I've realized as I was waxing the MKC today that my black plastic piece, sitting below the taillight with the reverse camera and license plate lights, was not fastened properly at the factory. On the inner side, it was fastened properly, but on the outer side, there seems to be 3 clip/tab segments. Mine had only the center fastened properly, and the left and right side was not sitting in the correct channel and hence was not flush with the bottom of that lip. Called up my salesman who took a look at his showroom model which had the issue only on the right side. Does seem to be a manufacturer issue, so just run your hand above the license plate lip to make sure if you own a MKC or are picking one up!
