Mercedes-Benz service campaign NCU - 2022070004
Mercedes-Benz filed this with NHTSA as a service campaign dated Oct 18, 2024, received Oct 21, 2024, about the fuel/propulsion system. It names 31 model years (2018–2024). A service campaign is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.
What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationMercedes-Benz AG ("MBAG"), the manufacturer of Mercedes-Benz vehicles, has determined that on certain Model Year (“MY�) 2018 - 2024 E-Class, S-Class & AMG GT (213, 217, 222, 223 and 290 platforms) vehicles, the low pressure fuel line does not meet current production specifications. Therefore, it is possible that accelerated aging in the area of connection could occur, resulting in a leak. A risk of fire can be ruled out. MBUSA will conduct an Emission Service Campaign. An authorized Mercedes-Benz dealer will replace the braided hose of low-pressure fuel line and install a heat shield over the new braided hose.
