A failure diagnosis method for power train components may include: establishing, by a server, a diagnosis model based on vibration big data indicative of failure of power train components; classifying and modeling, by the server, failed components among the power train components by using feature vectors extracted from the vibration big data; initiating, by a controller of a vehicle, failure diagnosis on power train components of the vehicle by an input command or setting of a driver; and diagnosing, by the controller of the vehicle, a failure of the power train components of the vehicle by comparing a feature vector corresponding to the power train vibration of the vehicle measured during the vehicle travels with the vibration big data modeled in the diagnosis model.
