The invention relates to a steer-by-wire steering system (1) for a motor vehicle, comprising: a steering handle (2) which can be actuated by a driver; a vehicle wheel actuator (11), which is configured to adjust a wheel steering angle of at least one steerable wheel of the vehicle; a reaction force actuator (5) which is connected to the steering handle (2) and is configured to produce a reaction force acting against a deflection of the steering handle (2); a primary adjusting device (12), which is configured to adjust the reaction force produced by the reaction force actuator (5), and a fallback adjusting device (14), which is configured to adjust the reaction force produced by the reaction force actuator (5) in the event of a malfunction of the primary adjusting device (12); the primary adjusting device (12) being further configured to output a manipulated variable (S) for adjusting the wheel steering angle, and the fallback adjusting device (14) being further configured to output a manipulated variable (S`) for adjusting the wheel steering angle in the event of a malfunction of the primary adjusting device (12); and the fallback adjusting device (14) and the primary adjusting device (12) being designed differently from one another. The invention further relates to a method for operating a steer-by-wire steering system (1) for a motor vehicle.
