My better half and I got stranded last Sunday. Battery started flashing, check engine light on and trying to get home, it started to lose power. Replace the battery as per dealers request,all under warranty. Stranded again with a new battery. Now our 2017 Chieftain with 7300 miles on it is in the shop ( going on day 3) and the dealer can't duplicate the problem. At first they were thinking Voltage Regulator but now they claim it's charging as it should. That doesn't make me want to take off on any long trips! Losing my confidence in the bike! 28th new motorcycle and I've never had this issue but they've all been Japanese bikes. Go figure!
