In my case it starts off fine then the numbers starts to miss parts to it (don't know of another word to describe it) then it returns back to normal after awhile. Like mentioned in the post above a cycle of the odometer brings it back to normal or even a gentle tap on the dash. I find it only happens when my headlights are on.....i still have a year left in my extended warranty so I will have them do the repair and report back with any updates.
