1. The vehicle experienced a fuel injector failure, which is part of the engine fuel delivery system. This failure appears connected to an open Fuel System Control Unit Software Update Recall (Campaign 2024080006) that has been open since May 2024 but was not performed on my vehicle, despite the vehicle being serviced at the dealership in January 2025 for other recall-related updates. The failed injector is still available for inspection upon request. 2. The vehicle began exhibiting symptoms of fuel system malfunction while driving, including rough idling, hesitation, and loss of power. A malfunctioning injector can cause the engine to misfire, stall unexpectedly, or run unpredictably, which creates a high-risk situation in traffic. This placed me, my passengers, and other drivers at risk, especially during acceleration or when merging into traffic. 3. Yes. The issue was diagnosed and confirmed by the Mercedes-Benz dealership, which stated that the injector had mechanically failed. The dealership also noted the open recall for the fuel system software update but claimed it was unrelated. I am seeking clarification because the timing and symptoms suggest there may be a connection. 4. The vehicle has been inspected only by the Mercedes-Benz dealership. Mercedes-Benz USA (MBUSA) has been contacted regarding the issue, but my case was closed without resolution and is currently awaiting review for reopening. MBUSA has not yet inspected the vehicle or the failed component directly. 5.Prior to the injector failure, the vehicle displayed engine hesitation, rough idling, and intermittent performance issues. Eventually, a check engine light illuminated. These symptoms began before the manufacturer-installed software update, and the issue appears to have worsened afterward.

- What component or system failed or malfunctioned, and is it available for inspection upon request? NHTSA Recall ID: 23V445, Fuel Pump Delivery Module How was your safety or the safety of others put at risk? Vehicle at risk to lose drive power, increasing the chance of crashing while operating. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No. Mercedes dealership states they will not repair recalls on the weekends only M-F. I work at the hospital M-F 0800-1700. The dealership will not make any accommodations in assisting me with my schedule to get car fixed. They refuse to let me make apt on Sat/Sundays and they will not have car towed to and from Mercedes dealership to my work. They have suggested for me to leave work around 1400 to drop car off and pick up a loaner for repairs M-F. This is not feasible.
Fuel/propulsion system, Aug 30, 2023
I recently received a notification from Mercedes-Benz concerning a safety defect in my vehicle, and to be honest, it's really concerning. The issue is with the fuel pump impeller in certain models, including mine. If this part malfunctions, it can cause the vehicle to suddenly lose power, potentially leading to accidents. Imagine driving on a highway and suddenly losing all drive power! The scariest part is that there's no immediate solution. They've informed me that the remedy isn't available yet and that they will contact me when it is. This has left me feeling unsafe every time I turn on the ignition. I'm sharing this because we might all be using our cars for trips or outings, and I believe it's crucial for everyone to be aware of the situation. I don't feel safe driving this care very time risking my life, and more over paying for damaged car Best regards, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Furthermore, the manufacturer has offered not other alternatives such as loaned vehicle or compensation for the risk of sudden motor failure.
