khoo, the hinge will be out of place after sometime because always open and close door. Coupe door is more heavy so the closing force is very strong. Hence causing the hinge to be out of place. Just re-adjust it and re-tighten the bolts. I also do this when I find the door hard to close and have to slam very hard. To avoid the hinge to be out of place so soon try closing the door more gently. I saw some people close door like want the door to fall off..slam!
