Cracked Rubber drain plugs

After soaking my clutches, when I took it all apart to clean it out I noticed that so many rubber pieces are cracked. By bike is a 2013 and it seems like it’s a bit premature. The parts I noticed today were the drain caps for the air box, the clutch case, and the cvt intake. Anyone else notice this? If not, you might want to check it out.
