Recently the clock in my Sante Fe has started to reset. It seems to happen at different times, once was after an oil change, once was when i restarted the car after putting gas in it. THe latest time was after the car sat all weekend without being driven. Can someone please advice me if there seems to a trend with Santa Fe's doing this and what the best option is.

I used to have this problem in my Lexus when the battery was going bad. Seemed strange because everything worked fine but the clock kept re-setting. Have your battery tested.

 

You have a bad clock! Seen many of them do this!
