A method of preventing a vehicle clutch from sticking includes a wear compensation actuation step of actuating a wear compensation device in conjunction with engagement actuation of a clutch actuator after an ignition is turned off when an actuation condition of the wear compensation device is satisfied, and a clutch control step of controlling a clutch position so that the clutch position returns to a disengaged state of the clutch actuator by reactuating the wear compensation device, when a clutch position based on an amount of variation in an actuation length of the actuation rod fails to return to the disengaged state of the clutch actuator during returning of the engaged clutch actuator.
