Service campaign NCU - 2022070004
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Mercedes-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.
