I read in another forum that this is an issue with the coupe. Here is the post:
My 3rd brake lamp cover on my Touring Coupe came loose on the left hand side after the first 1000 miles *and* a trip to Death Valley. I could have claimed warranty but I generally don't like anyone else working on my cars. I too thought that the Scotch mounting tape from Autozone would do the trick. It did until the window got hot from the sun and I was going over a rough road. The issue seems to be heat. After checking out the specs. of the various Scotch tapes online I ended up buying Scotch #4008 for it's high temp. spec. This part might be overkill but I used the tape in combination with Scotch 3X extreme Velcro fastener from Home Depot. This will add a slight thickness over the original material holding up the cover so the cover is slightly lower but it still seals. After 3000 miles the cover is still holding strong. I suspect that there will be more coupe owners reporting the same problem.
