Hours Used Reset Itself????

[Cesardajr]

i went to fill up the h2 and when resetting the computer,
i noticed that my hours used were at 5 hours at 60K miles!!!!
about a week ago the display said "service 4wd" i pulled over,
turned off the h2, then restarted, & all was well till i noticed my issue today.
i got home and ran a scan for errors and all clear no errors reported.
what could have happened? should i be on the look out for anything?
