2013 MERCEDES-BENZ B CLASSTransport Canada Recall #2020617
The official notice
Defect
On certain vehicles, the power steering control unit may corrode. If this happens, moisture could enter the control unit and cause it to fail. This could cause a loss of power steering assist. Note: This recall only affects vehicles that were originally sold or ever registered in areas of heavy road salt usage (Ontario, Quebec, New Brunswick, Nova Scotia, Prince Edward Island, and Newfoundland & Labrador).
Safety Risk
A loss of power steering assist would result in a sudden increase in steering effort, especially at low vehicle speeds. This could increase the risk of a crash.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to replace the power steering control unit.
