Broke rear subframe while driving. Made it home discovered the left rear suspension is almost completely detached from the vehicle. Researched the problem and discovered it-??s a known issue and a warranty extension has been provided for some vehicles including some models of my particular year and model but after contacting Mercedes is seems mine is not.

Rear right side Subframe rusted and broke off. Vehicle pulled to the right while braking.

- Roosevelt, NY, USA

Rear Control Arm Broke off of the rusted Rear Sub Frame assembly which was confirmed and inspected by my mechanic.

- Sparta, NJ, USA

The car was all over the road when braking and making banging sound. Had towed to 3 repair shops and all said Subframe was rotted out beyond repair. Mercedes Benz in golden bridge will replace subframe, but my cost is towing, labor and renting a car until it-??s fixed which can take up to 1 month.

When breaking at high speeds, the car feels like I will lose control of it. Has happened a few times and I thought I was going to hit the neighboring car. Took it to a repair shop and found out that the rear driver side subframe Is completely rotted out and the rear control arm is hanging. The car only has about 97,500 miles on it, has not been driven in high salt areas, and doesn-??t have any other signs of rust. Two auto body shops have told me this shouldn-??t happen on a car with that low mileage, and these cars, Mercedes c300s, are known to have this defect.

This 2013 Mercedes C300 with 88, xxx miles has significant subframe rust. This is unacceptable and is a safety hazard because the rust and corrosion will continue to spread and cause additional safety issues. This will cost over $4,000 to repair, but it is a manufacturer defect. There are a ton of similar complaints online, so this is clearly a systemic issue with this model that needs to be investigated.

- Enola, PA, USA

There is a defect in the subframe of the vehicle which causes it to corrode and rust out. Apparently, this is a known issue with certain years and models, and has already been recalled in Europe, but not the US.

- Hingham, MA, USA

Rear subframe rotted. Common issue, needs a recall. Control arm broke off on both sides of the rear subframe. Rear passenger lower control arm close to gas tank, can cause a fire if punctures through tank as well. Lots of swaying in rear as well

- Chicago, IL, USA

The subframe has rotted from insufficient protection. This car is unsafe to drive, many US consumers having same problem with this model where the subframe is rusted out. This is a major issue effecting thousands of cars of this model or maybe more

1. The component that failed was the rear subframe for the rear transaxle and wheel suspension system. It was inspected by a licensed MB service department and determined the drivers side of the rear subframe had rusted completely through and was separated from the frame. The passenger side of the rear subframe was also severely rusted and at risk of breaking. The subframe is currently being replaced. 2. The subframe to this vehicle holds the transaxle and rear wheel suspension in place, I noticed with a hard breaking the rear of the car swerved, slightly fishtailing. I immediately drove home and parked it until I could drive it to a service/repair facility. If this subframe had completely broken free the entire rear drivetrain would have been severely damaged or completely destroyed or worse, break free from the vehicle and cause a crash. 3. The problem is well known in the auto industry. My service center who inspected my vehicle described it and said it is a well known problem and they have replaced other subframes due to the same issue. I even spoke to an AUDI salesman today and they know of it and send these MB vehicles as a trade-in to auction and do not even attempt to replace the subframe. A recall for this problem of the subframe failure due to rust has already been issued for MB in Europe for quite some time but no recall in the USA. 4. This vehicle and component has not been inspected by the manufacturer, police or insurance rep. 5. no warning lamps or any other messages were illuminated to give any warning of a subframe failure due to rust. The first symptom of the problem is the loose rear end with hard breaking causing a slight fishtail of the rear of the car. I experienced this on my drive home from work and afterwards only drove it to my service center.

- Versailles, KY, USA

Rear sub frame failure due to corrosion. Failed part causes vehicle to lose control when applying breaks. Further broke sub frame has high risk of fire due fuel tank breach. Vehicle was inspected by Mercedes Benz technicians several times up to the point of failure, no advanced warning. Technician stated no lights, no warning signs until total failure occurs.

While returning from a long trip with my entire family, I initially lost control of the vehicle on a normal curve at 70 mph speed on a highway. We managed to stop without getting in an accident. After determining that it is not because of any tire damage and not understanding the problem, we continued with the journey driving at reduced speeds. From then on, vehicle was losing control whenever I try to brake. After narrowly missing few accidents, I realized the stopping distance also increased a lot. I almost hit several vehicles whenever I try to come to stop all of a sudden. Unsure of the weirdly behavior all of a sudden, I decided to stop at a nearby autoshop and get a quick check. Surprisingly the mechanic heard about these issues earlier and pointed us directly at the cause of this behavior. The issue is a ROTTEN REAR SUBFRAME. A part which is supposed to last for the entirety of its life, rusted from inside out prematurely. Learning this, I sent my family home in a different vehicle and brought mine towed. Mercedes Service center gave me an initial estimate of $8860 to repair and might increase once they start removing things for repair. After further research, I found out this is a very common issue. In other countries, Mercedes is replacing this free of charge to customers who report it as this is a safety issue. So I tried to reach out to Mercedes Corporate office and they declined to repair it Free of charge as there is no official recall on this issue. I am only glad that my entire family didn't end up in an unfortunate incident due a a cheaply made part. I urge NHTSA to look into this issue as soon as possible and help avoid lots of accidents due to this issue.

- Herndon, VA, USA

Rear subframe / crossmember failed due to corrosion. The rest of the car is in great condition, with no rot or corrosion. This is a regularly serviced vehicle. The part is recalled in other countries. Aside from the lack of a USA recall - the manufacturer is not providing any replacement parts. I am now without a car, and could have been killed if I didn't get it checked out. I do not see how it is legal to not provide parts to solve a life threatening issue caused by poor manufacturing. Should I drive the car anyway until it causes an accident ?

Rear subframe cracked; car has less than 95,000 miles and looks great. My two children of driving age were using the vehicle at the time, driving others as well. Fortunately, I happened to drive it not longer after the issue and took it to the shop immediately. They put it on the lift and saw that the rear subframe was cracked all the way through. As it turns out, it is becoming very common on this make/model--and it is nearly impossible to get a replacement. Mercedes Benz told me maybe sometime in 2023. In addition to having it inspected, I have since been in contact with several dealers and mechanics. Results are invariable: the part is in extremely high demand, Mercedes cannot fill the demand, and the wait is indefinite but long. There were no warning lamps, messages or other symptoms of the problem. In addition to the inconvenience, the car was very dangerous to drive. I am thankful that my son did not seriously injure himself or others while driving. The crack renders the car unstable at anything but the slowest speeds. When one brakes at any speed over about 20-25 mph, the car pulls violently to one side. Simply braking alone could cause a major, even fatal, accident. And any emergency maneuver could be disastrous. The car has been garaged since June awaiting a replacement that I am told will cost between $4000 and $6000! I am left with a vehicle that runs very well--but is unsafe to drive on a public roadway--and no way to repair it. Moreover, Mercedes cannot tell me when the part may become available (likely sometime in 2023).

Rear subframe of vehicle rusted under regular use conditions and the left trailing arm mount broke off as a result. This caused vehicle braking to become extremely unstable and dangerous, even at low/medium speed. This is a known problem from this manufacturer and the Fed government should take action to force recall.

rear subframe premature rust for a 2013 car I've been reading a lot many people have same problem it is a very expensive fix and I'm sure Mercedes knows about it. Also engine makes very bad rattling noise at startup which is also a very expensive fix and Mercedes issued a tsb bulletin thank you

I have a 2013 MERCEDES BENZ C300 Sport 4MATIC with roughly 90k miles. Car is in great condition, a well maintained vehicle that has been regularly serviced (receipts in hand). I recently sent it in for an oil change, air filter change, and to check out a slight rear noise that started a couple weeks ago. I was told the Rear Subframe is severely rotted, and hitting the gas tank. My car is completely un-driveable until this issue is resolved, and extremely expensive to repair. I also called multiple MBUSA dealers, and was told these parts are on back order WITH NO TIME FRAME. Therefore, leaving me with no car for weeks if not months. Based on my own research this is a wide-spread manufacturing failure, which was correct in newer models to prevent the corrosion. Not only is it crazy that the US does not offer free repair / a recall on this issue like OTHER COUNTRIES - Mercedes Benz is leaving people hanging due to the back orders. Curious if Canada / other countries also have this back order issue regardless of recall status. If not, MBUSA should most definitely be responsible to all its US customers whether its improving inventory or recalling the part. My plans were to sell the vehicle for a newer model BEFORE this problem arose. If the noise didn't start until after I sold it, the new owner could have easily been injured or killed. I service this vehicle 2-3 times a year for routine maintenance, and was never made aware of the issue. If I waited to take it in any longer I could have been severely injured as well. I am now without a car, because the frame was not properly protected during manufacturing. The fact this part is on back order for 2 months says it all. Strongly appreciate your assistance in resolving this safety concern.

Driving my 300 down the highway at around 70MPH and after lightly pressing the break, the car surved into right and left lane. I could have gotten into an accident, but luckily no other car was on the road. Taking my car to the mechanic it was discovered that My 2013 C300 has a rotted subframe, this was not caused by any damage but due to the part not being protected from rust. Rust caused the subframe to rot from the inside out. Many C300 have reported this issue, and the large number of failures on this subframe across my C300 and multiple models is concerning. This is a gross failure of a major safety component that can cause serious injury or death. My research showed this part has been recalled in Canada; MBUSA feels the need to wait to do so until a serious injury or death has occurred. The defective subframe is known and the new part-??s design has been amended to take into account this rust issue. MBUSA-??s decision exhibits a lack of accountability for a defective part and this issue needs to be promptly addressed for the safety of its customers.
