Thanks. When I went in for the sunroof and mirror (out of synch; needed to be replaced), they did a Schedule "C" tune-up which like an idiot i said fine to since i was in rush and heading out on a trip. Was charged 100% over the retail for the air and fuel filters and the pcv valve plus time to replace them, which I am sure amounted to about 15-20 minutes not the 1.5 hrs charged. I don't mind paying for the oil changes but simple things like filters are such a rip-off. Learned my lesson. On my jeep replacing the fuel filter was a bit tricky and not easy to get to. The service manager made it seem like the fuel filter on the H2 was similarly tucked away. But I know. Thanks Hummertech for the info. I think I'll leave it just fluid changes and rotating the tires to the dealer. BTW how often should the dealer scan the on-board computer for software updates?
