My passenger side window makes a rattling sound when driving. I have taken it to the dealer, but they gave me the dreaded, " we could not reproduce the sound you were hearing" nonsense. I have taken it to a different dealer before, and supposedly they put insulation in the A pillar. Do you think something needs to be lubed? It is louder over bumps but during normal driving it is easily noticeable. By the way I have a 6th gen coupe.
