I apologize if this topic has come up before. However, I notice with topics like the sunroof rattle, leaky trunk after rain, electronic quirks we get very helpful responses. Wouldn't it be useful to advise the build date on the car so we can all establish an additional data point? This way if a component or installation technique changes we might have more information if this is a new or old problem, one solved, or a new one. So when you mention the problem, quirk, etc. add the build date.
