My odometer is stuck on 75590 and it will go up to 75599 but then kick back to 75590 it just started this and the mileage is now off by 30mile (I track the miles closely as the car is a garage orniment) ... What is the proper way to fix this? Has anyone seen this before? It would be a shame to destroy the vehicles value by tarnishing the title etc over a 30 mile discrepency. I don't intend on selling the vehicle, however I would disclose this to a buyer if I ever did.
