A creak or squeak can be heard from the top of the front or rear doors. This noise is most notable when the windows are fully up. The noise is caused by the decay of the flocking material on the door seals. New door seals, Teflon tape, special lube, or a combination of all of these may be needed to eliminate the noise.

same problems, since 20 some thousand miles.. I have used silicone spray, it helped a little, but problem comes back.
Creaking as if the car is flexing on uneven pavement at highway speeds.
