If my front windows are lowered about an inch or so, and I close the door (not slam), the window shakes almost like it is loose or not secured very well within the door. I checked this on my Camry and the window doesn't shake or seem unstable. I don't know if this is just inherent behavior with the HL or if it is something I should have the dealer look at. Can anyone report their findings with this? I'd like to know if this happens on other HL's.
