The dealership "should" replace it for you. They replaced my door panel at no cost.

Just a FYI:

Mine had a few scratches, so I replaced the silver cover piece that snaps on to cover the screws, too. The small piece costs $65 for the drivers side, and only $33 for the passenger side. They are identical, mirror-image pieces. I guess more repairs have been performed on the driver's side door, and the 100% increase in price is a result of supply and demand.
