Just road in the back seat of my eight month old MKC. Noticed that the edge of the headliner above the door looks frayed above the whole length of the window. Closer inspection revealed that either the headliner was cut too short to tuck under the black rubber trim piece, or that trim is not tight enough to hold the headliner tucked in. It is a raw edge with the spongy underside exposed. Wondering if this defect can be fixed, and if it will be under warranty. Check the edges of your headliners!
