A vehicle failure-factor specifying apparatus includes (a) a peculiarity-presence determining portion configured to determine, based on a pre-failure driving state in a stage prior to occurrence of a certain failure in a vehicle, whether a peculiarity was present or absent in the pre-failure driving state, and (b) a failure-causing-driving state specifying portion configured, when the peculiarity was present in the pre-failure driving state, to determine whether the peculiarity present in the pre-failure driving state of the vehicle is substantially identical with a peculiarity in the pre-failure driving state of other vehicles. The peculiarity-presence determining portion determines whether the peculiarity was present or absent in the pre-failure driving state of the vehicle, depending on whether a frequency distribution of the pre-failure driving state of the vehicle is deviated from a frequency distribution of a non-failure driving state of a plurality of vehicles including the other vehicles in a non-failure case.
