We've only had a couple issues with our 2010 model.
The fiberglass delaminated by the outdoor receptacle, we've sealed it, but the small area of delamination is impossible to fix.
My wife dropped a bottle of nail polish out of the medicine cabinet and it broken open and left a pink streak on the bathroom wall. We added self adhesive stick tiles to the bathroom wall from Home Depot.
The floor at the entry door, up to the bathroom door became "soft" due to the high foot traffic in that area, and the floor had a butt joint there. I re-supported the floor from underneath and it is now SOLID!
