Where have you gained this knowledge, or is it your opinion? When you say known issue, as in it's just a Honda thing we're expected to live with, or known issue with possible fixes?Sunroof and roof lining rattles on cars with sun roofs is a known issue for Honda. Two problems: The roof lining itself has a reinforcing strip that surrounds the aperture for blind, fixed to the lining with glue. The glue wasn't very good and let go allowing the whole lot to vibrate noisily. The fix is a replacement updated rooflining, i.e. one with modified glue! As for the glass sunroof seal, the solution is a thorough clean and treatment with silicon grease. The creaking which is hugely irritating, is caused by stiction between the seal and the body paint.
The hugely irritating creaking is by design then from what you're saying with no solution, or none yet?
