Does the mileage erase from the car when a digital odometer is replaced?

When a digital odometer is replaced, the mileage typically does not erase automatically; however, it can be manipulated if the replacement is not done by a professional. In many jurisdictions, tampering with an odometer is illegal, and ethical practices require that the new odometer reflects the true mileage or that the discrepancy is documented. It's essential for vehicle owners to retain records of odometer replacements to maintain transparency regarding mileage history.
