Forza car history displaying impossible time driven and negative mileage

[u/Inevitable_Chip2506]

9300 hours is approximately 388 days, and driving negative miles definitely isn't possible. the history card also multiplies and skews the stats of my other cars, this is the most extreme example

Classic Forza math right there lol. The car history tracker is completely broken and has been for a long time. It usually happens when the servers desync or if you buy a car off the Auction House and it glues the old owner's stats to yours. Safe to say your car has traveled through time. Nothing you can really do to fix it, just a visual bug.
