ELECTRICAL SYSTEM, ENGINE
During regular use my 2023, Mercedes Cla 250, had a fault in the instrument display in which the display shut off completely. Only the media display remained on, however the media display is completely useless in this scenario, only the instrument display can show the speed in which the vehicle is traveling and the Rpm range in which the vehicle is being accelerated at. I was left stranded, hopeless, and endangered as a result of this catastrophic vehicle failure.

AIR BAGS
My clock spring is no longer working, it made all the buttons on my steering wheel stop working and i am afraid the airbag will deploy at random since there was a recall on cla models 2015-2018. I own a Mercedes cla 250 2018 but it is not showing a recall on my specific vehicle. Not only that but they no longer sell just the clock spring for my car, im assuming because of the recall. I am scared that my airbag will randomly deploy while im driving or that it will not deploy at all in case of an accident. It was diagnosed by an independent mechanic There was no other messages except when my left side airbag service needed message popped up

Hi there - I know my vin number doesn't recall the front stationary roof panel replacement but this came to my attention as I saw that the panel has faded the top coating and the edges have some very thin cracks I will say. I was not aware of such a thing but googling the issue I found out that NHTSA did start a campaign for this particular safety issue last year. Campaign No. 2024010012, March 2024. My Mercedes falls completely on the requirements for repairing/replacing this front panel as the model, year, and type of material of this panel but yet no recall with my vin number. Just wondering if this is a mistake or something else that I don't know. For now I haven't driven the car for the safety concerns until I have any explanations. Your response in this matter will be very appreciated ! Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Yes, the problem has been confirmed by an independent certified service center. This specific vehicle has not been inspected by the manufacturer, but this specific problem has been identified in other similar Mercedes-Benz years, make, and models.

When you start off at a slow speed, the rear end of the car starts making a knocking noise. We had it inspected by Mercedes-Benz and they said that it is the rear differential.

POWER TRAIN
Component or System That Failed or Malfunctioned: The component that failed was the partial-load ventilation valve, which is part of the engine’s crankcase ventilation system. This valve is responsible for regulating airflow and pressure within the crankcase during partial engine loads. A malfunction in this valve can lead to increased engine pressure, oil leaks, and potential damage to engine components. The component is still available for inspection upon request. Safety Risk: The failure of the partial-load ventilation valve put my safety, and that of others, at risk in the following ways: •Engine stalling or reduced power while driving, especially during acceleration, which increases the risk of an accident. •In some cases, oil leakage caused by excess crankcase pressure could lead to engine compartment smoke or a potential fire hazard. •If the engine performance is compromised, it may suddenly lose power on highways or intersections, posing a serious risk. Problem Reproduced or Confirmed: Yes, the issue was confirmed. The technician verified the faulty valve during a diagnostic inspection after I noticed performance issues and warning messages. Inspected by Manufacturer, Dealer, or Others: Yes, the vehicle was inspected Warning Lamps, Messages, or Other Symptoms: Yes, there were warning signs prior to the failure: •Check Engine Light illuminated on the dashboard. •Engine running rough or hesitating, particularly during acceleration.

I own a 2023 Mercedes CLA250 VIN: [XXX]. This morning I was driving 50 mph on a road with no traffic, no car in front or behind me, no trees or overhead wires and my sunroof imploded. I have the privacy screen closed which saved me from the shards of glass raining on me. I have included pictures of the roof as well of the poor quality of the glass that is used for the sunroof. I am shocked there is no safety film in that glass to prevent it from shattering. This was a terrible experience- I expected more from a Mercedes. I’m horrified this can happen.
