STRUCTURE:BODY
My wife and I were driving our 2015 C-Class Mercedes on a highway, traveling at roughly 55MPH on 2/25/24, at approximately 2pm, conditions were sunny but windy, when suddenly we heard a loud noise above our heads. The noise sounded like it came from around our sunroof, and it sounded as if maybe the car had been hit by a piece of debris, although neither of us saw anything. We looked in our mirrors but didn't see anything, and I also tried opening and closing the sunroof and it worked fine. I also looked in my rear view mirror and didn't see any cars behind me swerve, or in any way adjust their driving. Because there was no safe shoulder on that part of the road, we continued a mile or so further up the road and then pulled over to see if we could visibly see anything wrong with the car. To our disbelief, a section of the body of the car that is just above the front windshield and just before the sunroof, a piece I believe called the "front stationary sunroof panel" , was completely missing! We were unsuccessful at finding the piece. After some research in recent days, I believe this issue is related to MB recall campaign #2021070010, 22V-954 / 2023010004/5/6. If this is however related to the recall, the Mercedes dealership we took our car to on 3/1/24 told us it would cost us over $2,000.00 to repair. As I thought about a piece of the car simply flying off while driving, I realized how much of a safety hazard this could pose to others, hence this written report.

STEERING
Electronic power steering failed. The electronic power steering on this vehicle has failed several times, making it almost impossible to steer. When this occurs, steering requires a tremendous amount of force and puts the vehicle and driver at enormous risk of an accident.

SERVICE BRAKES, FUEL/PROPULSION SYSTEM, VEHICLE SPEED CONTROL
On the afternoon of February 6, 2024, as I was turning into my driveway to park in front of the garage, my car unexpectedly accelerated despite my foot being on the brake pedal. Despite my attempts to brake, the pedal didn't respond, causing the car to collide with the garage door and subsequently damage storage shelves and containers inside. My mother and two brothers were passengers, returning from my mother's doctor appointment, and she became trapped inside due to the garage door collapsing onto the car. Emergency services were called, and both the fire department and police assisted in freeing my mother from the vehicle. However, the police did not file an accident report since it occurred on private property. Subsequently, I contacted my insurance agent, and the car was towed to a repair shop recommended by the dealer. Today, I was informed by the repair shop that the damages are extensive enough for the car to be considered totaled by the insurance company. Fortunately, the incident did not occur while driving on the freeway or public roads earlier that day, potentially averting a more serious accident. Nevertheless, the ordeal has caused considerable stress and sleep loss for all involved. I have since reached out to the repair shop and dealer to conduct a thorough diagnostic analysis to determine the cause of the malfunction. I've requested copies of the data captured by the On-Board Diagnostics (OBD) system and Event Data Recorder (EDR), emphasizing that this data should not be deleted without my consent. However, I am uncertain about the next steps if the insurance company removes the car from the repair shop and how to access the requested data. Upon researching online, I've discovered numerous similar cases involving Mercedes-Benz cars, with over 20 incidents reported and 11 specifically concerning the same model as mine.

EXTERIOR LIGHTING
We had notifications on our dashboard that rear driver side (left) lights were out while driving car. We thought the light bulbs just had to be replaced. We brought to mechanic to just fix lights & they discovered the light ground wire burned out & caused light holder to be damaged as well where ground wire was. It caused rear driver side tail lights to fail. We had light bulb holder with wires all replaced on 2/23/24. This issue was a recall back in 2014 & seems to be a reoccurring issue with this part of the Mercedez 2011 C class.

ENGINE, FUEL/PROPULSION SYSTEM
I bought this car new in 2013. I maintained it at the dealer as per MB recommendations. Last service was in August 2023. Currently had 42K miles on it. Two weeks ago 2 unknown to me lights came on and I took it to the dealer. The diagnosis was total failure due to oil leaking into the computer system. Second problem was water in the subfloor affecting sensors. Coons Mercedes in Catonsville, MD has all records. I was told that the oil leak was not detected because it was internal and due to an engine design. I was informed that there are many others stuck with this problem. I was informed that I was driving a car that could become suddenly uncontrollable. This was very scary. I was told I needed a new car. My insurance company inspected it and determined it was a total loss. I complained to MB headquarters and HQ in Stuttgart. I told them that they need to buy a new car for me. I have not heard from them. If MB know that there is an engine flaw why are they putting peoples' lives at risk?

Check engine light came on. Error code indicates a PCV crankcase ventilation valve has malfunctioned. Code is P052E. This is a notorious problem with Mercedes, BMW and other European cars. It should also be considered part of the emissions system. Contacting the MB dealers, I cannot get a clear definition whether it is covered by extended warranties or any warranty whatsoever. They are vague as to "maybe, but not sure". I feel that there should be a recall to fix the defective parts involved with this error code.
