Mercedes\-Benz AG has determined that on certain Metris \(447 platform\) vehicles, the fuel pump impeller might not meet specifications in regards to material characteristics. As a consequence, the impeller might deform. It might therefore come into contact with the fuel pump housing, leading to a mechanical resistance. In some instances, this could lead to a shutdown of the fuel pump. As a result, the vehicle could lose propulsion, and increase the risk of a crash or injury. - [NCU\-23P2094109](/bulletins/10246043.md), 2023-12-04, Service bulletin: EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL.
