Bought car fall 2015 w/21000 miles. First very cold day (below 0 f), I noticed the heating system as well as defrost barely worked after driving 8 miles on a country road. This repeated itself several more times before I discovered TSB 14-063 where they discovered sand had been inadequately washed from the blocks after the casting process was completed. It then settled in the heater core blocking the system from adequate defrost and heat. My dealer app't was disappointing in that they essentially told me I was lying and nothing was wrong with the system. They claimed the temp probes showed a 1/10 degree between the 2 vents - of course, I never saw the results. My warranty expires in less than a month when it will then be my responsibility to flush it myself or pay them to do it !! it's now spring so I feel that waiting for a recall could possibly put me in jeopardy as visibility during cold weather will be and has been an issue. I have a copy of the TSB and see it's supposedly a 3 12 hr obligation, but the flat rate they show is 1. 1 hours which encourages their techs to do haphazard work. Dealer was buerkle Honda, st paul,mn and my app't was in early January 2016.
