I have a 2019 cvo limited with the Kahuna heated grips not working properly. They will barely get warm unless I hit a harsh bump like a bridge expansion joint or a big crack in the road, then they will heat up for a very short time (like a minute or two) then fade off. I've taken it in many times, and to 3 different dealers. They feel the grips warming slightly and say that the grips are working, that's having them set at 6 and they are barely warm! The last dealer finally agreed the grips should get way hotter and replaced the left grip with the controller. I rode it and the grips were no better than before. That dealer told me "that's as good as it gets". I've had other bikes with heated grips and know how they should be working. I'm very disappointed! I may replace the throttle side grip myself to see if that could be the problem. Another option I'm considering is replacing with aftermarket grips. Let me know if you figure yours out please, as mine are pretty much useless!
