I'll try and keep this short. Purchased a new Civic SI coupe recently. I had a Honda Moonroof Visor installed. When the car hits 35 miles an hour you hear a hissing noise like a tire loosing air. Long story short, worked with the dealer to determine its definitely the visor. Had it replaced, same problem. Comparing this to my 03 Civic SI with a visor, the new one cannot be fastened as tight to the roof as the older models so air gets under the weatherstripping (at least I think that is the problem). Has any one else had this issue? If so, did you get it fixed. I think the problem will be with all coupes (and maybe sedans), not just the SI. I'd like to hear from others so that I can maybe bolster my case with Honda. I plan to write American Honda and will keep people posted as to what I find out. If you have a similar experience, please let me know. It may help in my discussions with Honda. I think they can fix it by making smaller clips but I'm not a auto engineer.
