The universal joint gear may be subject to excessive wear due to insufficient torque in the screw connection of the steering coupling. As a result, the transfer of the desired steering torque might no longer be assured. This could result in the loss of rotational torque transfer between the steering wheel and the steering box which would make it impossible to steer the vehicle.
The recall concerns vehicles produced between June 2012 and January 2017.
