When all windows are up, you can hear some sort of creaking noise or rubbing noise near the top of the windows (both driver-side and passenger). Don't know if it's the window itself against rubber or the metal on the door against rubber. The sound sort of goes away when you lower the windows down a bit. I've seen threads where people use 303 aerospace protectant or Vinylex, but that seems to be just a temporary fix. Has anyone taken it back to the dealership and had them successfully diagnose it?
