A system includes a processor configured to wirelessly receive first usage data in conjunction with a wear-state report, indicating a sensed level of system wear, from a plurality of vehicles. The processor is also configured to aggregate and analyze the first usage data to determine common parameters and corresponding values indicative of the sensed level of system wear. The processor is further configured to wirelessly receive second usage data from a vehicle lacking a sensor capable of sensing the sensed level of system wear. Also, the processor is configured to compare values of the common parameters in the second usage data to the determined values indicative of the sensed level of system wear and report a likely wear-state to the vehicle lacking the sensor, responsive to the comparison indicating a level of system wear similar to the sensed level of system wear.
