Can you fix the discrepancy yourself, no.
Newer cars store the odometer value in at least 2 modules, cluster and ECM, and in some cases even the BCM. When replacing one of them, a diagnostics routine for handshake is required ("seed and key") to have the replaced module learn data about the car, being the odometer value one of them if applicable. I'd advise taking it to the dealership to see what assistance they offer.
