I have the same unit as yours, but a 2013 model year. The trim around my back door (kitchen door) does the same thing. So far, I haven't had a problem with the molding around the front (bedroom) door. I just push it back in, but I agree with Homer1959 - I think the molding is too long. When it heats up (from the sun) it wants to expand; but the screw at the bottom prevents that. So, the expansion forces it to buckle and come out of the track. I've considered removing the bottom screw, stretching the molding (cutting off the excess) and then reinstalling the screw. Glad to see it worked for Homer. Think I'll do it once the sun comes up.
