That's pretty severe. The only thing even close I've seen is the rear hatch/upper support rusting on the weld seam, but yours is obviously not rust... Is that rub point against the weatherstripping? I've not seen foam rubber cut through paint before.... Might be a defect in the original paint that just let go with a couple years of soft contact. You should at least be able to have one of their body guys to a professional job with some matching touch-up since it doesn't appear to be an outer surface.
