Warranty extension EW-Low Pressure Fuel Hose

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

This NCU replaces the prior NCU issued on July 30, 2021 and includes an additional population (33) of certain MY 2018 Baumusters covered under this extended warranty. Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has extended the warranty on the low pressure fuel hose that connects to the high pressure fuel pump, from the original New Vehicle Limited Warranty of 4 years/50,000 miles to 10 years/120,000 miles (whichever occurs first) on certain Model Year (“MY”) 2015-2018* vehicles. This warranty extension includes the replacement of the fuel hose due to potential fuel weeping on the fuel hose at the inlet connection to the high pressure fuel pump. Under certain cold ambient conditions during a cold start of the engine, the low pressure fuel hose at that connection may experience slight fuel weeping. A brief odor maybe perceptible by the occupants, but a safety risk, including the risk of fire, can be ruled out. This extended limited warranty applies to all aforementioned conditions that necessitate the servicing and / or replacement of the fuel hose under the standard warranty terms and conditions. The extended warranty is applicable to the following vehicles, which are flagged on a VIN-level basis in NetStar:
