Mercedes-Benz C200 complaints by model year
NHTSA defect investigations
Federal safety investigators have looked into a possible defect involving the 2015 Mercedes-Benz C200:
Desiccated Air Bag Inflator Rupture
From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited.
What 2015 Mercedes-Benz C200 owners say
Body & structure
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. [redacted]
The rear of the car would begin to slip during turns and when brakes were applied. When I had the issue checked out, my mechanic said that the rear subframe has severe corrosion, rust and holes. The subframe perforation is causing instability in the rear wheels, which is a safety issue. I took the car to Mercedes for an inspection and they confirmed the holes in the sub frame,with the inspector stating that the sub frame is "about to fall off". I believe this to be a safety issue as having the wheels or subframe fall off could cause fatalities. This appears to be a manufacturing defect given recalls for the same issue in other models of the 2015 c300. See video of the inspection of my car here: [redacted]
Suspension
The R&R rear subframe is showing premature corrosion that can cause structural failure. This can lead to rear suspension detachment, erratic driving behavior, and severe safety risks. This problem has been confirmed by the Mercedes Benz dealer. This has been inspected by the Mercedes Benz dealership. There were no warning lamps, messages or other symptoms of the problem prior me finding out it was failing. I had a multi inspection performed on my car due to another issues and the MB service dept found it during that time. Which means if I had never had the multi inspection done due to another issue I was having with the car, I would not have known.
Purchased this car in September 2024 for our [redacted] 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.
Fuel & propulsion system
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.
Fuel pressure pump hose on top of the engine leaks gasoline this is a serious safety concern the hot engine can catch fire easily, I noticed due intoxicating vapors in cabin while driving because car takes air from q side of the engine to the cabin. The car only has 28k miles on it.
