Hi there,
The odometer problem is normally caused by cracked solder joints on a circuit board located on the back side of the instrument cluster. The instrument cluster replacement by the dealer will cost up to $600.
Unless your vehicle is still under warranty, it is normally not necessary to replace the instrument cluster. You can easily repair it yourself in an hour or two, and at no cost. See http://www.odometer-repair.com for a detailed discussion on the problem and the various options for repairing it.
Good Luck!!
Thanks
