I changed out mine twice in 34,000 miles in my '04 and it looked much like yours. I haven't checked my '12 yet in 17000 miles but should next time I change oil. I had understood that the '12's didn't need changing as often. Should check it to find out I guess.
Bolt on 2012 is 2 or 2.2 ml longer than previous and bolt seat in pulley rework as well by Suzuki, please advise how it look when you check it. 2-3 photo would be good.
