A plethora of Mercedes-Benz models is being recalled in the United States for posing a fire risk.
An investigation from the German car manufacturer has revealed that trapped debris could damage the seal between the fuel rail and fuel injector, potentially triggering a fuel leak into the engine compartment. Leaking fuel could then contact hot parts of the engine and increase the risk of a fire. Mercedes-Benz states that a deviation in the production process meant the fuel rail and fuel injectors may not have been cleaned properly prior to assembly.
