The present invention provides an automated steering wheel leveling system and method. Particularly, the automated steering wheel leveling system includes a machine vision, a plurality of motor cylinders, a motor, and a robot, each operated by a process PC. The machine vision photographs a steering wheel to obtain position information of the steering wheel and determines a stroke of a motor cylinder and a grip position of a gripper using the position information. The plurality of motor cylinders move a plurality of grippers to steering wheel to secure the steering wheel. The motor rotates the steering wheel in order to adjust a zero-point of the steering wheel. The robot then moves the machine vision, the motor cylinder, and the motor to the steering wheel to align a shaft of the servo motor with a shaft of the steering wheel.
