I guess the old adage of "use it or lose it" may apply.
Or it was just a manufacturing or assembly defect...

If I understand correctly, the poster is referring to the cover that shades the moonroof, the topic of this thread...Interesting that an interior panel is called a "cover". I'd have thought that would be an exterior part, but no biggie. Many interior ceiling panels are secured by adhesive, and that adhesive can fail. But whether it's secured by adhesive or fasteners, it can be repaired. Dealers often don't "repair" stuff, they usually replace stuff.
Yes, there is a lot of turbulence with the windows down. I would consider opening the shade fully (retracting it) when you're driving with the windows down. All that fluttering is likely to weaken the shade I would think...I never open my sunroof/moonroof, and always keep the shade ajar about 2" to allow air to circulate to hopefully prevent the gliue that's holidng the shade on from getting hot and delaminating. What I hate is, when driving with the windows down, that shade is bouncing and vibrating all over the place. My concern is that it's that constant, semi-violent motion that's going to cause the shade material to let go. Incidentally, the shade vibrates no matter if it's fully closed or slightly opened. Lots of wind turbulence with the windows down.
