What 570 owners told NHTSA about the 2013 Mercedes-benz C-class Hybrid

So I took my car to get new tires and the tech told me that my rear subfram was rusted and cracked ,unsafe to drive . I called mercedes and they asked to take it to the dealership and get a quote. I did this and there response was to do nothing .this issue has been recalled in Germany and also Canada. But nothing done in United States. This is a serious safety issue .let's say I never got my tires and never found out and was traveling 70mph down the freeway and had to hit the brakes hard for whatever reason and this part fails and breaks. Everyone in my car and whoever else my car collides into life's would most definitely be in danger

The driver side suspension mount to the rear subframe has rusted through. While applying the brakes the car pulled radically to the left almost causing me to lose control. This is a known issue from what I can determine but Mercedes has refused to issue a recall. The car cannot be driven until this is fixed.

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 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.

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!

I needed new tires and the tire dealer reported that my subframe is rotted bilaterally. He suggested I do not invest in tires until it is replaced and to notify Mercedes as there may be a recall. This defect caused instability of the frame that secures the tires. The safety risk should go without saying. Any rotted structure that supports the car and/or secures the tires is an obvious safety risk. After reading the multiple complaints posted under “structure” for this make and model, it appears that yes, this problem has been reproduced and confirmed by other owners and mechanics. I am presently picking up my car from the tire dealer and driving it directly to the Mercedes dealership…so they will be aware and able to inspect it. There were no warnings or alerts that my subframe rotted. I do not believe this is something that could be measured with a sensor to trigger an alert electronically.

Vehicle inspection during oil change has revealed that the vehicle has a broken rear subframe. Apparently this is a common problem in Mercedes C300 vehicles, which are subject to recall for this issue in Germany and Canada. Vehicle report here (with video of broken subframe): https://xoxocar.com/inspection.aspx?inspectionid=9e225031-77b5-4304-8ec1-a10c859b90f0&print=true

Car with just 130,000 miles needs significant subframe and related parts replaced. There are countless discussion boards of similar failures across Mercedes Benz car lines. The estimated cost of repairs at the dealership exceeds $5000 just for subframe work. When braking the car veers to the left and the right end tries to swing around. Again, this is noted on multiple discussion board. MB has consistently demonstrated negligence in addressing this as service advisers state this is not uncommon and is seen often. A recall/replacement is warranted.

The rear subframe has failed. I have felt some swaying and decreased control when driving the car at higher speeds especially when braking and taking curves. My safety has been put at risk as the wheel could go out and cause an accident. I brought the car to the mechanics at Goodyear as I thought it was the brakes. They informed me that the rear subframe was rusted from the inside out and was loose at the left rear toe arm. I am setting up an appointment to get this taken care of. As I am calling, mechanics are letting me know that the subframes are on backorder in the range of months. They say they are seeing this more often. I contacted the dealer and they said they can get a used one and replace it for $5200. I believe that if this is becoming more common where new ones are on backorder and this is obviously a safety issue then a recall should be issued. The car is only 9 years old and is garage-kept. I think that this idea of that type of rust at this point is absurd.

My rear sub frame is rusted and unsafe to drive.. There seems to be a recall in Canada (I think) but not in the US. this is an unsafe issue that needs to be fixed. All local repair shops are aware of these and have several that need repaired as well.

Started noticing strange chassis behavior when braking. Braking hard would result in car leaning left, then leaning right when foot taken off the brake. Car appeared to "sway" on braking. Hard to control direction of vehicle on braking. Consulted local mechanic who put the car up on a lift. Discovered rotten rear subframe on left side. No substantial rust or rot on any other structural components. Looked into this issue online; no recall discovered. Found multiple instances of this rear subframe rot occurring to other owners of similar-year C300s who were then also quoted thousands of dollars in repairs. Car is not safe to drive until the subframe is replaced. The wrong pothole could cause the rotten rear subframe to snap and potentially cause more damage to the vehicle and injury to the driver and others. No warning lamps or other system messages to warn of this problem. A safety inspection performed at an authorized Mercedes-Benz service center on February 22, 2021 found no issues with the vehicle.

2013 Mercedes Benz C300 4dr AWD. Corrosion of Rear Sub-Frame (aka "Rear Axle Carrier" or "Suspension Cross Member") (New Part #: 207-350-97-02. Old Part #: 204-350-01-41 + other numbers). Car experienced erratic behavior under all braking scenarios. Extremely dangerous behavior under heavy breaking (65 mph to 25 mph). Life threatening severity of issue. 2 personal experiences. 1: Stopping at a yellow light in a quick fashion (55-0 mph, no abs required), car pulled hard to left and almost pulled me into curbing on left hand side. It felt like the rear end was on ice and was going to do a 180 partial spin. 2: Pulling off a highway into a turning lane and braked hard to slow down for right hand turn (65-15 mph). Car pulled about 8 feet left and almost put me back into full speed traffic. Same uncontrollable "on ice" feeling. I was on a road trip and had car towed to independent mechanic in the town I was visiting. He found holes throughout rear sub-frame member on drivers side and passenger side. Mounting points for suspension components were not structurally sound. He said I was lucky the control arm didn't break loose and puncture the gas tank. Corrosion was limited to sub-frame. The rest of car was "Nearly Perfect" in the words of the mechanic. Called Mercedes Corporate and they advised towing car to local MB dealer for inspection. MB Lancaster determined car was unsafe to drive. I am currently pursuing a good will repair case that has been initially denied. Parts are back ordered for 10+ weeks. I've called several dealers to source the part and nearly dealers have orders placed to Germany for these sub frames. Repair + alignment is approximately 4k USD. In 2018, Mercedes has issued Official Service Information Supplemental Notes (SI35.00-P0009A) to technicians to look for premature corrosion issues. This is free of charge replacement in UK and Germany already and a recall in Canada. US needs to catch up quick before death occurs.

I have a 2013 Mercedes Benz C 300 sport, and I felt my car shaking if I drive above speed of 35-40. Took it to Mercedes Benz dealership is Rockville center NY, they told me it is my subframe, which cost parts $2496 and labor $3704, Total $6196. Sad part is that my car is in excellent condition and Mercedes refuse from even helping to reduce cost.

Vehicle was taken in for standard maintenance and I was informed that the rear sub-frame had a rusted through hole on one side and was rusting on the other. This vehicle is well maintained, garaged, and has normal annual maintenance with the dealership. There was no prior warning that this was an issue or "normal wear and tear" was causing this problem. The repair is quoted to be over 5k and I was told it is/will be essential because of a safety issue. Through some brief internet research, it appears like this is a larger problem and could have catastrophic problems if it is not caught before it fails.
