Bought 2006 Murano 6 weeks ago. Second day after purchase clock reset itself from apprx 9 a.m. to 5 something. Happened again 3 days later apprx 9 a.m. to 4 something. Happens every 2 - 4 days, the time it happens varies, the time it resets to varies. Been to dealer 3x, they say they've replaced the clock and there is nothing else they can do unless they "see" the problem occur. Talked to a regional guy, quite patronizing, he was of no help either. Corporate says there is no record of this problem having been reported prior so they have nothing to go on. Has anyone had this problem? If this was a matter of just keeping poor time I wouldn't complain but it changes by hours.Becoming frustrated but otherwise love my mo!
