It's a problem that I'm seeing more often. In this case it's problem I could improve, but not fix completely. I should rephrase this. It can be completely fixed but the costs are exorbitant and no one is willing to pay for it. Fingers point in all directions. The builder will say I didn't install it so it's not my fault. The dealer will say I installed it, but the builders design is the problem. The owner says "Why me? It's not my monkey, not my circus. Just fix the damn thing."
