The left rear subframe separated from the main frame causing the car to pull to the left when braking. I had an episode where I was stopping for a traffic light and the car started fishtailing and I almost lost control of the car. Following this episode, I took the car to a mechanic who advised me that the car was unsafe to drive. My mechanic also told me that he has repaired a number of these vehicle with the same problem, and that Mercedes Benz has extended their warranty from 4 years 50,000 miles to 20 years unlimited mileage. They did the extension after someone filed a class action suit in Georgia about the problem. The vehicle is presently at a Mercedes dealer awaiting the new subframe.

To Whom It May Concern, I am seeking assistance regarding my 2014 Mercedes-Benz C-300, VIN [XXX] . I repurchased this vehicle from the London Nissan Dealership on [XXX]. It currently has about 120,000 miles, and I have driven an additional 15,000 miles in the past two years. Less than three months after purchase, I took the car to a Mercedes-Benz dealership in Knoxville, TN, for repairs on May 16th. Now, my vehicle is at James Motor Company in Lexington, KY, where they diagnosed a faulty steering column that needs replacement at a cost of $1,630.00. I have already taken this car to the dealership twice for issues in under two years. The problems began when the vehicle wouldn’t start one morning; the steering column was locked despite a fully charged battery. This failure could have led to a serious accident, especially since I drive frequently for work and school. There were no warning signs prior to this incident. The dealership has confirmed the steering column issue and can provide inspection upon request. I also have a list of parts needed for the repair available. Given the nature of this malfunction, I believe it warrants a recall. Thank you for your attention to this serious matter. I look forward to your prompt response.

I purchased my vehicle from the Mercedes Benz Dealership and received a recall letter in the mail stating that driver side deployment may occur. After receiving notice I brought the car to the dealership to get the recall repaired. I've been driving around with a false sense of security believing that this issue was repaired. However, recently, while I was driving the driver side airbag unexpectedly and abruptly deployed and injured me. This is a major safety concern and car owners should be notified and made aware that the issue can still occur after the recall was repaired. I contacted Mercedes Benz and they did not issue any additional notices to inform customers of possible recall issue reoccurring due to manufacturer defects even after the repair was made. Additionally, I believe the driver side Takata airbag/inflators may have also been defective because of the injuries I incurred from the forceful explosive eruption of the airbag.

While I was driving my car the driver side airbag abruptly deployed. The airbag inadvertently deployed; the car did not crash into anything to cause the airbag to deploy. When the airbag erupted it caused injury to my head, face, hand, arm and wrist. I believe the airbag is defective because I have lacerations on my face possibly due to sharp objects ejecting from the airbag and the impact as well as excessive smoke and fumes emitted after the fact. I believe there might be a manufacturing defect in the airbag because it seemed as if it exploded with excessive force causing harm to myself as well as inadvertent eruption. There have been some recalls issued on the motor vehicle and I did take the vehicle to the Mercedes car dealership to get all of the recalls repaired, however this incident occurred after the repairs were made at the dealership.

The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. I have taken it to a service center for a very expensive repair as they have to remove the door panel, replace/reattach the part and put the door panel back.

Car has approximately 60,000. miles. Upon it's state inspection Mercedes Benz service center indicated rear subframe is rusted. Service advisory says it is okay now, but will need to be replaced. Searching Mercedes forums, I've noted this is a n oft reported issue. Many do not realize there is an issue until it breaks and car pulls to one side at rear upon braking. Others have experienced rusted brake lines at the same area as the subframe issue. Others have noted damage to the gas tank from suspension parts banging the fuel tank after it breaks. I realize this is a 8 year old vehicle. But the vehicle shows zero signs of rust on the undercarriage except for the subframe. Sure seems like a manufacturer's defect that should be recalled by Mercedes. Because of safety concerns, I now have to decide to repair or trade the car because of safety concerns. But the rusted subframe zaps the value I thought I had in the vehicle for a trade. What is the protocol for manufacturer's to issue safety recalls. Sure seems like this one qualifies.

Malfunction of rear subframe and control arms due to rust causing the subframe to crack. When breaking the rear wheels swerved almost causing a collision on the highway. My mechanic inspected the car and deemed it unsafe for driving as this can cause injury or death to me and others. The car is currently being repaired. This problem is being ignored by MBUSA, however MB in Europe acknowledges the faulty metal and will repair at no cost. There were no warning lamps or messages that made me aware that the subframe is rusted and cracked.

I purchased my car one year ago from a Mercedes dealership - 8/31/2021. I brought it in for service at the same dealership a week ago and they told me the rear subframe rusted from the inside out and it FAILED inspection. The parts are $5,100 and not available until some time in Q1 2023. There is no way a car rusts from the INSIDE OUT in one year. I have another vehicle in the same driveway, same everything and there is no rust anywhere. We have had all of our cars at least 10 years. This was a "new" car for us. MBUSA said they could do nothing because I own the car and didn't get financing from them. My dealership so far is not helpful. My service guy (he has been for 10 years) says this is common?? My client (a different car manufacturer) says it is not and it is terrible. I don't know why it rusted but this is a defect in the car because we didn't flood it. It's dangerous.

Rear subframe of vehicle is starting to become rotted/rusted out and may fall apart at any time. My Mother has the same body style car as me (2011 c300) & she was recently driving at around 60mph and all of the sudden, went to step on the brakes and the car swerved across the highway uncontrollably. She took it to a mechanic who said the car is not drivable and showed me how badly the subframe was destroyed. This is due to a Mercedes Benz manufacturing issue where they tried cost cutting which turned out very poor quality materials for this very important assembly. My car only has ~55,000 miles and is just about 8 years of age. This issue should never happen for a vehicle with such low miles and such a short life, especially from a prominent and distinguished automotive company. This is a Huge Safety Concern, and I am Scared that this subframe will fail without warning and at a high speed, which can likely cause me to be involved in a major accident where people are killed or seriously injured. I would even consider getting rid of this car, which would be unfortunate since it is gorgeous and seems almost brand new, although I cannot afford to sell this & buy another car at this time. I have researched online about this problem, and turns out, it is Very Common with this body style c300 ('08 - '14). There are hundreds, if not thousands, of individuals within the USA who are having this exact same issue with as little as 60,000 miles. Most are happening around the 90,000 mile m

Failed component: The subframe on my Mercedes C300 broke on one side and was almost broken on the other. It would be available for inspection as it is sitting in the Mercedes dealer bone yard waiting on the part to be shipped from Germany around September 17th. It also ruined my back tires & now I have to replace them too. I understand that in the UK the Mercedes dealers are fixing this problem free of charge but there seems to be no recalls! Safety: I was entering the freeway on a rainy afternoon. My car was fishtailing very badly. At first I thought is was the highway itself as we had not had rain for quite some time. I tried to accelerate 4 or 5 times with the same fishtailing. I pulled off the busy freeway onto the shoulder & sat for a few minutes to collect my thoughts as I didn't know what was wrong. Then I drove very slowing to the next exit & a few more miles home. I drove very slowly a few miles the next morning to the Mercedes dealership. Inspected: The Mercedes dealer told me the subframe was broken and the car was not drivable! Couldn't find the part in the US so ordered from Germany with at least more than a month to wait. Warnings: There were absolutely no warning lights what so ever! Additional: The dealership did not have any loaner cars. I went for 5 days without a car to drive. I finally purchased another vehicle as I depend on it to do my job. It is going to cost over $4,400 to fix.

My 2014 Mercedes C300 4matic currently has a rusted through rear subframe. I know this has been reported to your Bureau numerous times by various people. This affects all 2008-2014 C Class and E Class Mercedes (as I used to work for a Mercedes dealer). Mercedes is trying to avoid liability at the sheer cost and man hours required to replace these parts. This is a MAJOR safety hazard, and has caused numerous drivers to lose control of their vehicle when they do in fact break off at one of the weld joints. The car is 8 years old with approximately 90k miles. This is a STRUCTURAL part of the car, and should never have to be replaced. Subaru dealt with suspension recalls on their vehicles, and I believe Mercedes should be reliable as well. Thousands of these cars are a ticking time bombs on the road. This issue was confirmed by my personal mechanic, and he stated this will not pass the next inspection (luckily I have 6 months left).

This car has 63,792 miles on it and has been continuously garaged and well cared for. All maintenance has been done timely and by Mercedes-Benz of Tysons Corner (Virginia) since it was purchased there on 01/08/14. All required maintenance was completed as advised and the car was covered under a 7 year 75,000 mile warranty. At the recent regularly scheduled yearly maintenance service completed on 12/28/21 we were advised that the that the "rear sub-frame is beginning to rust through and has a hole on the right rear (RR) and the recommendation was the "replacement of rear sub-frame soon" at an estimated cost of $4,242.40. This car has never been in an accident. In speaking to the MB service representative about this issue, I was advised that this problem has happened to several C300's from the period 2009-2014 and that Mercedes Benz was not accepting any responsibility for the issue in the US but had issued recalls in other countries. He said Mercedes maintains that it is a "wear and tear" issue. This car has not been abused and has been well maintained. This is not an area of the country where you would expect to see this type of corrosion unless the part was defective in some manner. In researching the problem on the internet, several people write about experiencing a failure of this part although the cars were older than ours and had more mileage on them. It appears to be a safety issue should the part rust through as it could puncture the gas tank or cause the rear wheels t

WHILE DRIVING ON 95 HIGHWAY TAKING AN EXIT ( MAKING A RIGHT TURN ROUNDABOUT) THE STEERING WHEEL LOCKED ON ME PREVENTING ME FROM CONTINUING IN THE DIRECTION OF THE EXIT CAUSING ME TO ALMOST CRASH INTO THE METAL RAILINGS; BECAUSE MY WHEELS NOW WHERE LOCKED IN A POSITION THAT WOULD FORCE ME TO CRASH INTO THE RAILINGS HAD I NOT STOPPED. I STOPPED AND TURN THE CAR OFF AND RESTART FOR THE STEERING WHEEL AND SYSTEM TO RESET AND UNLOCK. THIS INCIDENT OCCURRED AROUND 2018 OR 2019. I NOTIFIED MERCEDES OF WHAT HAPPENED AND I RECEIVED NOTIFICATION OF A RECALL ON THE STEERING. I HAD THE RECALL CHECKED ON MY VEHICLE AND THOUGHT IT WAS FIXED. HOWEVER, TWICE IN NOVEMBER 2020 MY CAR WAS STATIONARY WHEN TRYING TO START THE CAR, THE STEERING WAS LOCKED AND THE IGNITION WOULD NOT START. THEN AFTER MAKING SEVERAL ATTEMPTS CAR EVENTUALLY STARTED. I CALLED MERCEDES AND I WAS TOLD OVER THE PHONE BY MERCEDES IT COULD BE MY KEY FAUB. HOWEVER, THIS HAPPENED A 4TH TIME ON DEC 24, 2020, NUMEROUS ATTEMPTS TO START CAR AND CAR WOULD NOT START, STEERING WAS LOCKED. CAR HAD TO BE TOWED TO DEALERSHIP. WAS TOLD BY MERCEDES THERES A FAULT IN THE STEERING LOCK MODULAR. THE ELECTRICAL WIRING IS FAULTY AND THE ENTIRE STEERING MODULAR HAS TO BE REPLACED. THIS IS A MAJOR SAFETY ISSUE, AND CAN CAUSE ACCIDENTS WHEN IT MALFUNCTIONS WHILE DRIVING. I ASKED ABOUT THE RECALL THAT WAS ON THE STEERING AND WAS TOLD THE RECALL ADDRESSED A DIFFERENT ISSUE WITH THE STEERING.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.

Most recent recall on file: Nov 1, 2019. Source: NHTSA Office of Defects Investigation.
