STRUCTURE:BODY

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)

ENGINE

Check Engine Light - Code P052E71 - Positive Crankcase Ventilation Valve Performance. The component failure can lead to increased exhaust gas emission, oil leaks, and internal engine damage resulting in unsafe operation. 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.

Repair cost can be in excess of $2,000 if not covered under the added warranty.

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.

UNKNOWN OR OTHER

My 2016 CLA 250 having multiple electrical and driving issues that are not recalled. I’ve researched online and found most of these issues are common. 1. Dashboard screen and radio console lights turn off completely. USB connection triggers electrical symptoms. Front and Back seat window control (driver) triggers electrical symptoms and sometimes corrects the problems. Trunk opens by itself while parked and/or stopped at red lights. The instrument cluster has times multiple warning lights turn on and stay on. At times the fuel needle drops completely down as if I have no fuel in the car. The instrument cluster lights stay on after I have turned the car off and locked it as if the system is confused. I have more issues but those are a few to name. I also have video and pictures to prove these things happen randomly then the vehicle can go back to operating normally. I’ve taken it to service and all they have done is reset the warnings.
