According to the German manufacturer, the two vehicles affected may have loose bolts securing the steering coupling as a result of a manufacturing fault.
If the coupling detaches from the shaft, it could cause a loss of steering control, increasing the risk of an accident.
The two recalled units were sold between 1 May 2013 and 31 May 2013.
Owners of the affected two C-Classes will be contacted via mail, and are encouraged to present their vehicle to their preferred dealer for inspection and, if required, repair.
