STEERING, WHEELS
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.

UNKNOWN OR OTHER
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.

STRUCTURE:BODY
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.

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.

SERVICE BRAKES, SUSPENSION, STEERING
While driving normal highway speed and braking suddenly the car violently pulls to left. Same occurs when driving normal city traffic . Good afternoon I am following up on a major safety issue #11453988 concerning a 2013 C300 Mercedes. I reported this a few weeks ago as this safety defect can cause personnel injury when the defective part fails . As noted earlier during normal braking the car pulls hard to left or right . With normal highway speed driving and emergency braking the car will violently pull left or right possibility into oncoming traffic and or fixed objects . Please reply with update into this major safety defect concern . PS the part number in question has been changed from number 2043500141 with new number 2073509702. This part is not available in the US currently and has a lead time of 30 days from Germany. With the long lead time and the need to travel to work it is a major safety issue that can be avoided. Thanks George

The camshaft adjuster failed on my vehicle and created start up issues and had to be replaced at 123K miles. While not an immediate safety concern, the camshaft adjuster failure could lead to engine failure and is an inherent issue in this vehicle make and model. This is a flaw in the vehicle and Mercedes did not notify me of any recall or warranty terms.The repair code was confirmed and repaired by an authorized Mercedes dealer for $2800.There were no warning lamps however I experienced engine start up issues. I contacted Mercedes as was advised they would open a case to review potentially partial warranty coverage however did not receive any type of resolution.

AIR BAGS, SUSPENSION
The contact owns a 2013 Mercedes-Benz C300. The contact stated that the air bag warning light was illuminated on the instrument panel. Upon taking the vehicle to the dealer, they discovered corrosion underneath the rear subframe. The corrosion caused 2-inch sized holes to be formed on the passenger’s side of the rear subframe. The dealer also discovered corrosion on the wire of one of the seats which resulted in the air bag warning light being illuminated. The manufacturer had been notified of the failure and agreed to cover 50% of the cost for repair of the vehicle. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 119,000.

I noticed that my car was pulling heavy to the left when I stop and strange noise in the rear of the car, after taking the car to the mechanic he told me that the car rear subframe on my 2013 Mercedes Benz c300 was rotted, the control arm bracket completely broke off on the left side and the right side is also cracked. it appears that this is a common issue in areas of heavy road salt usage during winter months, the dealer told me that the car has a rotted rear subframe problem and the subframe could break out in months.
