SUSPENSION
I took the car to Mercedes for service and they found that the rear suspension frame had extensive rust and recommended that it should be replaced. The car only has 87,000 has been garage kept since buying the car in 2013 and has been serviced my MB. The frame has two quarter size holes at the same location on the left and right sides. MB was made to recall this in both Canada and Europe. MB stated that this is a known issue with this car. Why has the NHTSA not forced MB to recall this car? MB knows that if part fails the entire rear drivetrain separates from the car. My understanding is this effects most C-class E-class cars, plus the repair is over $4,000.00 This should be on MB not the consumer.

SEAT BELTS
Issue: Front driver and passenger seat belts do not fully retract despite completed recall service. The seatbelts often "puddle" behind the seats when unbuckled, and sometimes get trapped between their seat and adjacent door. My car was recalled and serviced under Mercedes Campaign 2021020010 to fix this in October 2021. Also, the right front seatbelt was replaced in October, 2018 under Campaign 2017050023. The first paragraph of the Mercedes Recall Campaign Bulletin states, "...certain C-Class Cabriolet vehicles (A205 platform) with PRE-SAFE might not meet the requirements of FMVSS 208, S7.4.5., as the front seat belts might not fully retract to its stowed position. In this case, certain regulatory requirements under FMVSS 208 might not be fulfilled. If the seatbelt webbing does not fully retract into its stowed position, the consumer may find the operation of the seatbelt inconvenient and not wear it, increasing the risk of injury in the event of a crash." In its step 1, the bulletin states, "The seat belt strap must retract into its final position automatically. Provide manual assistance with rolling up the seat belt strap if necessary." Having to provide manual assistance to retract the seat belt does not meet the definition of "must retract into its final position automatically". Further, it does not meet the aim stated in the bulletin's first paragraph about the importance of the seat belt fully retracting. The labor time spent on campaign was only 0.10 hours (6 minutes), so nothing more than a cursory inspection was done, and not any actual service work. I spoke with my local Mercedes dealer and the Mercedes USA customer service rep. They are both Ok with manually feeding the seatbelt into its slot. This is unacceptable and does not meet FMVSS 208. Both the dealer and the Mercedes USA say I can pursue proper fix at my expense. This is a failed recall service and I should not have to pay to explore a proper remedy.

The car started fishtailing slightly when the brakes were applied at speeds around 25 MPH. First it was taken to a Mercedes dealership on June 24th where they said it need a sway bar and tires. They were not sure that would address the issue. When we went to get tires, the tire person said the control arm was connected to nothing in the rear. The rear subframe was rotted to the point that there was not a place to even weld it back on to and needed to be entirely replaced. The fact that Mercedes missed it is shocking in itself, I can only assume (we bought the car used) it was rotted from use in winter weather before we got it. The repairs have been estimated to cost between $2200-3800-.

The item that has failed is the rear subframe of the vehicle. It is available to be viewed. It is still on my car, as it has not yet been replaced due to the cost. When braking, the front of the car will pull left and back feels like it is pulling to the right, as if you are spinning out. The problem is that the subframe is rusted out at under 100,000 miles. I just hit 100,000 and it has already broke completely. I was told by the dealership that this is a safety concern where the back of the vehicle could fall off, there words, not mine. I have been in contact with Mercedes Benz corporate and they said since I am past 50,000 miles, there is nothing they can do. There were no safety warnings, recalls or lights in the car that has given me any indication there was a problem until it broke and I felt it during breaking. This issue seems to have happened to many individuals driving the Mercedes C300, as it is not just a small number. Currently, MB has this backordered due to the number of cases. They should be responsible for a recall for the price paid for their vehicles.

The rear sub frame has rusted out and broken causing the car to veer suddenly to the left during braking. A quick search of the internet reveals that this is a common problem with this car. The dealership has quoted me $4,000 for the repairs.

SERVICE BRAKES, STEERING, WHEELS
The rear subframe is rusted and broken, alignment is out, and steering wheel is off centered. Given the history of this model car, it has been under recall in multiple countries outside the United States. This is a common and very dangerous issue that needs to be addressed in the United States because if you call any auto shop or Mercedes they all say it is a common problem with 2008-2014 C-class models. When you look up this issue with this car it has multiple threads saying that the rear subframe has rusted and broke when it is not supposed to.

The door handle on the driver side stopped opening. I believe it became broken on the inside. Upon researching it I found that this is a recurring problem in many cars of my same make and model. Additionally I took the car to a mechanic to be fixed and apparently the dealerships are keeping the part in stock because this is a common issue. The car will not open from the inside without purchasing an entire new panel to repair it. This seems like a recall issue as a present safety concerns. This cost over $1200 to repair.

The dealer noticed that the rear suspension subframe had rusted and corroded with a hole. They rejected the passage of the state safety check. A review of online forums shows this is a common problem in these years and Canadian and German counterparts of MBUSA have issued recalls because a third party supplier provided the parts without sufficient corrosion protection. See eg. https://mbworld.org/forums/c-class-w204/805501-rotted-rear-subframe.html

I was traveling at roughly 55mph when I had to make a sudden deceleration due to another vehicle pulling out in front of me. When I applied the brakes, the car unexpectedly pulled violently to the left nearly causing a head-on collision with an on coming vehicle. After Googling the symptoms/scenario, I found that this can be caused by a rusted and failed rear suspension subframe. The control arms for the rear wheels become detached from the subframe as a result. Based on my research, this seems to be an extremely common occurrence. So much so that Mercedes Canada and Mercedes Germany are replacing the defective subframes free of charge as they’ve concluded the cause to be “inadequate corrosion protection” applied to the inside of the subframe. It seems as though they’re rotting from the inside out. After learning everything about the issue, I pulled my car on to ramps in my garage and was able to confirm that my subframe had indeed failed. This is a serious safety issue which is being addressed elsewhere. During my research I was unable to find a recall or TSB related to this issue, only hundreds of people stating that Mercedes forcing customers to cover the cost to repair this extremely dangerous manufacturing defect.

Hello, I have 2016 Mercedes Benz c300(W205). Recently I got a Check Engine Light with P052E71. And the solution is to replace the Crankcase Ventilation Valve/Oil Separator, Intake Manifold. These parts are positioned on the right side bottom of the engine. It was a labor intensive work which required to remove multiple parts to gain access to the oil Separator. Considering the Issue Persists from W205 and Mercedes Benz has not done anything to rectify it, the cost is actually burdened upon the customer.

My Mercedes C300, 2013, 46,123 miles has 2 holes in rear sun frame, rendering it unsafe to drive. Dealership and MB will not acknowledge this is a common problem with this make/model. Recall for very same problem in Canada & other nations has been issued but not in USA. Dangerous situation!!! $5,200 to repair! On a premium brand auto with less than 50,000 miles. Please help!
