Windshield defrost failed when hvac module temp door failed similarly to failures in 2015 and 2016 year models. GMC confirmed and repaired the 2015 and 2016 model years; but, has so far refused to acknowledge or repair my 2017 model; even though, from information available to me, it is the same part with the same problem. The dealership quoted me $2,500 for repairs.
