2015 MERCEDES-BENZ C200

I have been informed by my dealer's service unit that the rear subframe of my car (2015 Mercedes C class) is rusted with holes. My understanding is that this can affect the integrity of the structure and cause problems while driving. According to your website [XXX] ) , this should be covered under a warranty extension. However, Mercedes says that my car is not, and to fill out this form if I believe it should be. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. What component or system failed or malfunctioned? The low-pressure fuel feed line (Part No. 274-070-35-00) and its associated clamps connected to the high-pressure fuel pump. Availability: State: The defective hose is currently on the vehicle and is available for inspection. If the repair proceeds, I request the dealership to retain the failed part for my inspection. 2. How was your safety or the safety of others put at risk? The failure resulted in raw fuel leaking directly into the engine compartment. This creates an immediate and severe fire hazard, as gasoline is being released near high-temperature engine components. Furthermore, the strong odor of gasoline entered the cabin through the HVAC vents, exposing passengers to toxic fuel vapors while the vehicle was in operation. 3. Has the problem been reproduced or confirmed? Yes. The defect was confirmed by Mercedes-Benz of Orange Park (Dealer Code: 64111). The technician performed a 'cold start' inspection and verified fuel le

Strong gas odor coming from vent when heat and AC is on. Odor was causing dizziness and had to drive with window open or vent off. When opening the hood gas odor was also present. Brought to the mechanic and found fuel lines leaking. Went online and found out this is a very coming problem. I had to spend $657. to repair. Mechanic stated Mercedes issued a service bulletin but not a recall.

Purchased this car in September 2024 for our [XXX] son. Upon inspection at our local Mercedes Dealership on December 1, 2025, we were informed that the rear subframe should be immediately replaced as there is a rusted hole in the subframe, "compromising the structural integrity of the rear of the vehicle." We were informed that the prior bulletin issued for 2010-2014 C-Class models did not include our 2015 C-Class. We were quoted over $5200 to repair the subframe. There were no warning messages, lights problems that were noted, prior to inspection. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I took my car for service and they found a rusted rear subframe, with a small hole in it. I was informed that the car was not safe for my annual trip from NJ to FL (about 1000 miles). I was also told that this defect was a recall for cars through 2014. My car is a 2015 and I have the same defective part - which is supposed to be manufactured with rustproof material. I am requesting that this car be recalled and the part replaced by the manufacturer.

The car suddenly glitched and locked itself—with my dog, my purse, my phone, everything—inside on an extremely hot day. There was no one around, and it was terrifying. I had opened the passenger door for my dog to climb in, and as I walked around to the driver’s side, the doors somehow locked on their own. Panic set in immediately. My dog, my phone, and my purse were all inside, and I had no way to call for help. We had just finished a walk, and then this happened out of nowhere. I had to run around searching for someone who could help. Eventually, I found a stranger who called the police, and they had to break the door open because it was over 100 degrees outside. I was terrified my dog would pass out from the heat. There were no warnings, no alerts, no messages. If it weren’t for that random stranger who happened to be there and willing to help, I don’t know how I would have gotten my dog out. It’s a reminder of the kindness of strangers, but the glitching car was truly t

My car’s rear subframe was so badly disintegrated due to severe corrosion. It made the driving so dangerous when braking and nearly caused an head-on collision. I have reported this issue under tracking number 11701609 and would like to provide pictures on the corrosion issue.

My wife first noticed loud noise from the back of the car when braking. Subsequently, when I drove it one day after, the car lost balance and nearly went into the opposite direction of the road on a two-lane street. The MB dealership later confirmed the problem was a severely corroded rear subframe that needs to be repaired at very significant expense. This is a serious safety issue that could have caused a head-on collision for me and my wife as a passenger on that occasion. I believe this issue warrants a full investigation by the NHTSA. I understand other Mercedes models such as the 2008-2015 C300 (W204) had the same corrosion issue and was under a recall but my car model (W205) was not covered by this recall. Thank you for your attention to this matter. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
