I did have a problem with the top (below the rear window) coming out of the rear track at the bottom of the top. The cloth fastner started on one side and slowly worked its way out of the track until it looked like it may come all the way out. I was going to take it to the dealer and have it fixed, but I partially opened the top which relieved the pressure on the cloth and I slipped the holder into the rear track and closed the top. Worked like a champ and no problems after my fix.

I have no idea what the correct terminology is for the various compnents that comprise the top are, but I am just conveying the idea. No technical accuracy intended.
