A park lock system is used in vehicles to provide a coupling between a rotor of an electric motor powering the vehicle to part of the chassis of the vehicle to, in an engaged setting, prevent rolling of the vehicle when the vehicle is parked on a hill. The park lock system may however also be engaged while the vehicle is rolling. In such a case, high loads may occur on parts of the vehicle's powertrain due to sudden deceleration of those parts. To reduce the deceleration after engaging the park lock mechanism, a resilient member is introduced. The resilient member is arranged to resiliently deform and slow the sudden deceleration, decreasing loads on parts of the powertrain due to the deceleration. By virtue of these decreased loads, smaller and/or lighter components may be used in the powertrain which may be advantageous for the size and/or weight of the vehicle.
