Mercedes-Benz S400 Hybrid: 12V557000
RepairPal Expert Overview
Our Quick Take:
A fuel leak can develop due to an error in the manufacturing process of the fuel filter.
What Should You Do?
Mercedes-Benz will notify owners of affected vehicles beginning in January 2013. If you are experiencing any fuel odors or a visible fuel leak is found, please call your Mercedes dealer. You should also consider not driving your vehicle and having it towed to the nearest dealer.
Due to a manufacturing defect, a crack can develop on the fuel filter when the vehicle is operated in high temperatures. This crack can result in a fuel leak, increasing the risk of a fire. Dealers will replace the fuel filter to correct this concern.
