The only problem I've had with our Generac is the battery charger board going duff a few years ago.
Ours was used 5 days a week for almost two months when the crew used it to build the house, hydro never made it onsite until about two weeks before the end of the build. This gave the genny a proper break in period as opposed to having the genny installed, test fired for couple of hours and then fired up once in a while for exercise.
Pure speculation on my part but I don't think many generators are initially run long enough or hard enough to get properly broke in.
