FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
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.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
All on a sudden the entire screen goes blank. It has happened at least 4 times and each time the service center does some patching and it works for a few month. When it happens, all the safety features are off including reverse camera. Also, no way to set the temperature or turn of the AC. In both cases, it can lead to significant damage. The recent incident happened when I was a very busy area and without any safety feature, the car was pretty much un-drivable.

UNKNOWN OR OTHER
I am attempting to submit a complaint against the Mercedes-Benz product and other auto manufacturers that follow this process. Mercedes provides no spare tire so this has been replaced by a "fix a flat" system that you can presumably use stop a tire air leak and then drive to a shop for repair. The fix a flat does not work when the tire is blown out or shredded so when this happens you are left with needing to have the vehicle towed to the dealership if using Mercedes' Roadside Assistance or to another shop at your own expense. Towing to a Mercedes dealership captures you to use the replacement parts in their inventory and costly labor charges. The time it takes to replace a tire is ridiculous considering a spare tire could be put on in a fraction of the time. There are approx. 30k miles on our vehicle and it has had to be towed twice for tires where the fix a flat did not work. Is this a safety issue? Absolutely, if you are driving outside of a city and the tire blows out then you are left with few options to resolve this and you better be in an area with cell phone coverage to contact Roadside Assistance otherwise you are stuck. I understand that "run flat" tires are now used but then why didn't Mercedes provide these automatically when our 2022 vehicle was purchased? These details need to be made know to consumers because the time and money spent for tire replacement on these vehicles is considerable and we are averaging having to deal with this once a year so far.

FUEL/PROPULSION SYSTEM
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)

ELECTRICAL SYSTEM, ENGINE, BACK OVER PREVENTION: WARNINGS
Throughout the year, the car had many issues, the blind spot sensors and glass sensors didn't work, and it constantly showed that the stop/start system wasn't working. Twice, the car turned off by itself at a stoplight. Since everything is controlled through the car's large monitor, including the navigation, air conditioning, and all other functions, the monitor frequently shut off and it was necessary to turn it off and on again, or wait until the next day for it to work again. The scariest incident happened during a heavy rainstorm. I was driving on the road surrounded by other cars when my car suddenly stopped abruptly and began to park itself in the middle of the road. All sensors failed! The cameras were going in and out without stopping, all sensors were beeping loudly and flashing, the check engine light came on, and the blind spot sensors wouldn't turn off. I couldn't do anything with the car or control it. I turned the car off and on four times just to get it off the road. When I called Mercedes, they didn't think it was a serious problem and made me an appointment for a month later. I brought the car in, but they didn't give me any timelines or updates on what was happening with my car. I called them for five days, but they didn't even look at it. Please help me resolve the issue with my car and the dealership!

ELECTRICAL SYSTEM, LANE DEPARTURE: BLIND SPOT DETECTION, FORWARD COLLISION AVOIDANCE: WARNINGS
Upon starting my vehicle today the center screen did not power on. The vehicle displayed several messages indicating various safety features were unavailable, including blind spot assist, lane keeping assist, parking assist, etc. Additionally, the exterior cameras (e.g., reverse camera) were inoperable as well. Since the center screen controls the sound system and climate control system, those systems were also unavailable. I restarted the car several times but the screen remained off. I purchased this car in August 2022 and have driven it approx. 3,600 miles - this is the second time this issue has occurred. The first time happened in Sept 2022 and it resolved by itself the following day. However, I believe this problem presents a safety concern since most, if not all, of the vehicle's various safety systems are disabled when it occurs.
