My 'oil change' maintenance light intermittently came on (and off) starting at 6000 miles (after an engine start). Set to flexible, said 40% life left when looking at maintenance screen. Assumed the algorithm was confused

. After the oil change (1st one, free at dealer), idiot light reset, the maintenance light came on after ~100 miles! I went to the screen, turned off other two notifications (scheduled maintenance and tire rotation), wrench light stayed on. Turned off oil change, light went off! Turned back on (left other two off), so far wrench light has stayed off, but it's been only a few days.
