Evaluation of Fleet Maintenance Data as a Data Source for Repairability Ratings

摘要

This study, performed under Title II of the Motor Vehicle Information and Cost Saving Act, is an evaluation of the feasibility of using automotive fleet maintenance data as a source for vehicle make/model repairability ratings. The study involved detailed analysis of the following: the availability of fleet maintenance data including the type of data maintained, the accessibility of this data and the number of make/models represented by fleets; the cost of obtaining available data from fleets and of improving/expanding this data to support a government-sponsored rating program; and the potential biases statistical problems involved in using fleet maintenance data to ascertain vehicle make/model differences in automotive system/subsystem/component durability.
