The recall affects 946 examples of the new-generation C-Class in Australia, and according to the official recall notice posted on the Australian Competition and Consumer Commission website, it is due to "the steering coupling lock", which "may not have been correctly engaged".
According to the recall notice, the issue "may result in a rattling noise from the steering column or in extreme cases the possible loss of steering control".
A Mercedes-Benz Australia spokesman told CarAdvice that the precautionary recall affects 470 customers despite being issued for 946 cars (which includes dealer stock, cars yet to arrive in dealerships and press evaluation vehicles).
Owners will be informed by mail, or at their next service. The fix for the issue takes 30 minutes and will be performed at no cost to the owner.
