The oil change reminder popped up on our JX recently. I was all set to make an appointment at the dealer until I noticed that it was just at the dealer back in September for its 7,500-mile service. It seems when it was in for service the dealer set the reminder pop-up to be at the manual's more severe, 3,750-mile interval. No big deal as it's really easy to reset the monitor. We've got about 3,500 miles to go now.
