Hi there! Anyone experiencing the problem of the "service 4wd" error coming on while driving in 4hi auto? The funny thing is once i've parked and restart my engine the error light disappears, and after driving around in 4hi auto it comes on again randomly without warning. It may be 10km or 20km but it just pops up randomly, without any known pattern. Dealership says they have checked all parts - fad, transfer case etc but there doesn't seem to be any problem. Anyone of you met with this problem? Thanks!
