Methods and systems for diagnosing vehicle systems using vehicle sounds, vibrations, or both, are provided. In one embodiment, a system comprises one or more sensors and a processor. The one or more sensors are configured to measure a sound, a vibration, or both, produced by one or more vehicle components. The processor is coupled to the one or more sensors. The processor is configured to compare the measured sound, vibration, or both with an expected sound for the one or more vehicle components, generating a comparison; and diagnose a vehicle system or device using the comparison.
