whether it is problem of muffler or the rear brakes, if it is not my fault I will ask the dealer to fix/repair it. But if my Honda sucks, then all Honda cars suck as to me. I'd believe it is not my fault as I drive this car normally, 70% of the 30K mileage was on highway, brakes were not used that much though, and muffler should not leak by this time unless someone hit it deliberately from the below which I myself did not do it. My car has endured only two winters and the third one is just beginning.
