So I just bought my first G two days ago, an 05' G35 6MT Just rolled over 76k on it. I noticed that my trip odometer doesn't add miles as I'm driving. I push the button to switch the trips but nothing happens there. Also, with my gas gauge, when I start it up it sometimes reads the right amount. Other times it likes to shoot up past a half tank when I know its less than a qtr left in it. Sometimes it'll drop back down where its supposed to be at. So if anyone could help me out here I'd greatly appreciate it!!
