I recently bought an 09 Civic and have found that if I have my front-door windows open an inch or so for ventilation that they rattle/move when closing the front door (gently). I also notice a distinctive/annoying ‘tinking’ noise if I drive with the windows open a few inches. This doesn’t seem to be the case for the back-door windows.
Is there a defect or is it the ‘new way’ to make economic cars today?
The solution to your problem is spelled w-a-r-r-a-n-t-y.
When the car is next at the dealership for maintenance, request that they take care of the rattling windows under the terms of your Bumper-to-Bumper Warranty.
