In situ vibration-based verification of vehicle doors

In situ vibration-based verification of vehicle doors may be performed to identify defects in the doors. An example vehicle includes a vibration exciter affixed to a door and a vibration sensor affixed to a window of the door. The example vehicle also includes a processor coupled to memory storing expected vibration data. The processor performs, via the vibration exciter, a sine sweep on the door and measures, via the vibration sensor, a vibration response of the door to the sine sweep. Based on the vibration response and the expected vibration data, the processor determines whether the door is defective.
