My headliner is separating from the roof in the front of my 2012 Escape 19". It is sagging down across the front about 4-5 inches. I have been traveling betwwen extremely hot conditions to cool this summer. Perhaps that caused the foam or adhesive to break down? Does any one have a method to reattach by injecting adhesive under the headliner (preferred), or reattaching with capped screws? Cant find a thread that addresses this problem. Thanks!
