We have discovered an issue included with "Gran Turismo 6" Update 1.15. Sorting the cars in "Garage" by "Distance Driven" will change the value to "0 mi". Please note the actual distance is not lost as it is saved internally and we are working on a solution to address this issue.

As a temporary workaround, if the driven distance value on your car changes to "0 mi", please select that car as your current one, then switch to a different car.

We will publish a further notice once we have completed working on the fix to address this issue. Please accept our apologies for any inconvenience this may cause.
