here is one thought -- did the carpenter who installed the knobs put them on too tight so that it cracked the paint and now that paint is chipping/peeling?

have you taken pictures and sent them to the company?

are your hands wet (from the sink or something) when you go to open those doors? Water is definately not a friend to fine cabinetry.

My cabinets form Crown point have a spot on the sink base where it is peeling/chipping away because I haven't been careful enough to wipe up the water soon enough. I had a leeky garbage disposal. i just used the touch up kit to fix it though and it looks fine
