I have a 2 week old CX9. As part of the deal, I was given a cargo cover for free. The first one was installed by the salesman. When I got home, I tried unhooking the cover to retract it. I called the salesman the following day and he told me that a replacement cover will be ordered for me. After a week, I got another cargo cover. Before installing it myself, I made sure that the cover retracts before installing it and after installing it. Today, April 29, when I tried to retract the cover, it again won't retract. I only got the cover on April 26. Is there any trick that I need to know to retract the cargo cover?
