I've had the OEM heated grips on my 2012 Roadster from day 1. Over 60k with no issues. You do need to ensure there is a bit of freeplay in the cables where they attach to the grip to prevent fatigue failures. Since I installed the grips, made sure there were no sharp edges and wire strains where the wiring entered the handlebars. Seems to have worked.
