Mercedes-Benz has issued two major recalls in the United States, both related to a fuel pump issue that could cause vehicles to shut down.

The first recall covers 143,551 passenger models while the second covers 20,500 models of the Mercedes-Benz Sprinter and Metris. In both cases, the recall notices state that the affected vehicles have a fuel pump impeller that may not meet specifications “with respect to material properties.”

A defect can cause the impeller to deform and if it comes into contact with the fuel pump housing, this can lead to mechanical resistance. This could shut off the fuel pump, causing the vehicle to lose traction and increasing the risk of an accident or injury. Mercedes-Benz says the problem is due to a deviation in the production process of a sub-supplier.
