STRUCTURE:BODY
My car failed PA State inspection due to a hole and rusted rear subframe. I have determined that there is a recall associated with this issue but that my vehicle just missed the recall limit. The recall affected 2008-2015 models (C Class with chassis 204). My vehicle is a 2015 C Class with chassis 205. It is evident that my vehicle has the same structural/construction defects as the previous years and should have been included in this recall. I have provided photographic evidence (attached/uploaded below). This is a very expensive repair that I should not have to pay for. Please review and consider having this included in the recall process so that I can be reimbursed for this costly repair as it is the result of a faulty construction process. Thank you. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

STEERING
While driving on the freeway car pool lane with my wife, a sudden vibration in the front tires was observed, the car felt like it was pushed to the right then to the left even though it was in the center of the lane. Told my wife, "something is wrong with the car!" Thinking that I may have had a flat tire, I slowed down, the car went into a violent flat spin until the right rear end of the car hit the center lane divider. Airbags deployed. 911 was called, we were assisted by Highway patrol to the other side of the freeway. As the car was put on a flatbed tow truck, the tow truck driver commented that one of the front wheel was not turning. We found out that the right rack and pinion broke. The car was declared a Total Loss.

UNKNOWN OR OTHER
The panoramic sunroof is faulty. Doing a simple search online showed that this is a common problem amongst my vehicle model where parts are loose or misinstalled and it is a safety concern in a potential accident or rollover. My dealer is now looking into it and it is also an excessive out-of-pocket cost to make the vehicle safer. Something I do not expect from a high-end vehicle manufacturer. I identified this due to the rattling sound in the ceiling/sunroof.

UNKNOWN OR OTHER, LATCHES/LOCKS/LINKAGES:TRUNK LID:LATCH
The issue is that the trunk lid closes abruptly and unintentionally. On Saturday, February 3, 2024, as I was putting a shopping bag in the trunk of my car, the trunk lid closed abruptly without my pressing the close button and hit my forehead. The impact was such that my eyeglasses flew off my face and hit the ground. The pain was severe and two days later, I still have pain. While there was no tear to the skin, there's a bump on my forehead and is still painful. The head injuries generally do not show adverse symptoms until months after the incident. I called the Mercedes Benz corporation and after they checked the car VIN, said there had not been any recall for this specific issue. However, searching the internet, there are reports and complaints about this exact defect.

ENGINE, FUEL/PROPULSION SYSTEM
My 2015 Mercedes Benz vehicle is rarely driven as I took public transportation to work and has ~55000 miles. However, the engine has started throwing error code P052E verified by an independent dealer - crankcase ventilation valve failure. It means the engine could shut off amid driving and I did research and it seems like a very common issue that Mercedes Benz car owner encounter and feels like a severe car defect.

ENGINE, ELECTRICAL SYSTEM
First day leasing the vehicle within 6 hours lights malfunction and malfunction warning on dash to seek workshop, vehicle was taken for inspection to original dealer (Mercedes Benz of Bakersfield). During inspection I added additional concerning complaints about passenger door not closing correctly/wind noise seeping through when closed, and hood not closing promptly. One month into leasing vehicle passenger window malfunction, took for inspection and repair to original dealer (MBofBakersfield). Concerned with caution for me, my family, and friends when in that vehicle for giving faulty signs so early. One year into leasing vehicle check coolant warning on dash, took for inspection to original dealer. I am now more concerned as it went form electrical to coolant components losing coolant with no reasoning from original dealer service other then a top off. Vehicle drive is rough. 1 year and 6 months into leasing vehicle, again check coolant warning on dash. Took in for inspection, gave no reasoning from original dealer service dept, other then a top off done. Vehicle drives rough. While driving 70mph, a vehicle behind was approaching quick when I went to excel to merge vehicle seemed to be slipping in gear/slow down. No warning lamps on, Quickly decided/managed to merged to next lane so vehicle behind didn’t hit us as we were slowing down With 2 children in the back seat. decided to exit to nearest exit to pull off as it felt unsafe to drive, as exiting and slowing down vehicle began to shake, knock, and make loud bangs. Managed to pull over, and check dash for messages for any type of warnings. No warning lamps, but many symptoms of a faulty unsafe vehicle. Had vehicle towed to original dealer service for diagnosis and report the unsafety incident that occurred with absolutely no warning lamps. Inspection lead to repair of engine but nothing done about no warning lamps/electrical system

FUEL/PROPULSION SYSTEM, VISIBILITY/WIPER
I have a fuel smell in the cabin of my car which started about 3 weeks ago. I have drove the car a couple of times and it was pretty bad, also my sunroof almost blew off the car while driving to dry the car after removing the salt from the streets after the snow. I have since parked it in the garage to avoid any further damage. I will submit pictures so you can see the sunroof.

FUEL/PROPULSION SYSTEM
During cold starts the fuel injectors/clamps leak causing strong gasoline smell inside the cabin. After research online this is a common issue with W205 systems. I am beyond surprised this has not been investigated and reported as a safety recall as it can pose a fire hazard. Please investigate and Mercedes should be fixing this issue….
