The official notice
Defect
On certain vehicles, the power steering return hoses may detach at their connection points. If this happens, power steering fluid can leak. This would result in a loss of power steering assist and power steering fluid could leak onto the road. Note: This is an expansion of Mercedes-Benz Recall 4695079 (Transport Canada Recall No. 2020-517).
Safety Risk
A loss of power steering assist may result in a sudden increase in steering effort, especially at low speeds. This could increase the risk of a crash. A power steering fluid leak could create a road hazard.
Remedy
Mercedes-Benz will notify owners by mail and instruct you to take your vehicle to a dealer to check the power steering return hose connections. Dealers will install a clamp at the connection point, if needed.
