A lot of people have had theirs fail. It is not problem to take you bike in and get them fixed. Some have expressed their concern that while they are waiting for replacement parts and then the time it takes to get the mechanic scheduled to work on the bike, it adds to an lot of frustration. But if you can get your dealership to order the parts and schedule a time that works for you, then you get them replaced - over and over and over and then again ----- over again.
My bike did not come with them, but I bought them and had them installed. I am now on set 6 ----- no I did not stutter ------ my sixth set of HD heated grips. When they work they are wonderful. But don't count on them exclusively, as they seem to know when you really want them, and pick that time to fail.
Good Luck!
