Campaign No. : NHTSA ID Campaign Desc. : TBA 23V878 23P2197660 December 28, 2023
Replace High-Pressure Fuel Pump This is to notify you of the new Recall Campaign to replace the high-pressure fuel pump on 7 Model Year (“MY”) 2023-2024 GLC and GLE (254 and 167 platform) vehicles. The recall campaign will be visible on the www.NHTSA.gov website and may generate questions from customers.
Affected VINs will be flagged in VMI as “PENDING” on December 28, 2023.
Background
Mercedes-Benz AG (“MBAG”), the manufacturer of Mercedes-Benz vehicles, has determined that in certain Model Year (“MY”) 2023-2024 GLE (167 platform) and GLC (254 platform) vehicles with the M254 engine, the bolting of the high-pressure fuel pump might not meet current specifications. Issue What We’re Doing Parts In this case, the seal formed between the high-pressure fuel pump and tandem oil pump might be impaired. Thus, fuel and oil might leak and potentially spill onto the roadway, increasing the risk of a crash for the following traffic. If fuel or oil comes into contact with hot components, a risk of fire cannot be ruled out.
MBUSA will conduct a voluntary recall. An authorized Mercedes-Benz dealer will replace the high- pressure fuel pump on the potentially affected vehicles.
Remedy is not available at this time.

Foreign States
Country : Germany Chronology :
In the beginning of October 2023, MBAG initiated initial investigations based on an internal quality review in an engine plant. This review revealed that the screws used to mount the high-pressure fuel pump in the engine plant might have been too long. Subsequently, investigations were initiated to determine potential consequences of the issue described. These investigations lasted until late November 2023 and determined, that the issue may result in a leakage of oil / fuel. In parallel, during November 2023, MBAG reviewed the fastening documentation together with the engine plant to determine which vehicles could potentially be affected. On December 15, 2023, MBAG determined that a potential safety risk cannot be ruled out and decided to conduct a recall.
