A suspension system for a vehicle having sorbers, each provided so as to be associated with one wheel and provided between sprung parts and unsprung parts, includes step motors, each being used to change damping force characteristics of one of the shock absorbers by open loop control, and a controller for outputting control signals to the step motors so as to change the damping force characteristics of the shock absorber. The suspension system further includes stoppers, each provided so as to be associated with one of the step motors for locating the corresponding step motor at its reference position at which a reference damping force is produced. The controller is used to adjust the step motors, which are thrown out of synchronism after the step motors have been located at their reference positions by the stoppers. According to the thus constituted suspension system for a vehicle, it is possible to prevent driving stability from being lowered even when at least one of the step motors is thrown out of synchronism.
