In general, techniques are described by which provide vehicle diagnostics and maintenance. A device comprising an interface and a processor may be configured to perform the techniques. The interface may be configured to communicate with a plurality of sensors to obtain a plurality of sensor signals representative of one or more states of a vehicle. The processor may be configured to apply a trained classifier with respect to the plurality of sensor signals to identify one or more components of the vehicle that result in a change of the vibration during operation of the vehicle.
