Failure Date: 08/15/2025

The electronic steering wheel lock went out causing the car to not start. Upon checking the internet to see if anyone else was having this problem I found that it was a problem many Mercedes Benz owners have had and it's an expensive one. It's not just with my particular model and it's not limited to older models of the brand either.

2 Steering problem

Failure Date: 06/10/2025

I drove vehicle to publix with no problems. When I tried to start vehicle, key turns but car does not start. There is no cranking sound. I called a mechanic friend and after extensive diagnosis he determined it was the esl module which controls the steering. Fortunately I was not driving the vehicle when the esl module failed. There is a recall on Mercedes Benz C300 from 2012-2017 for the esl module problems but the 2011 is not included. It should be recalled since it is a safety hazard and it appears others have had similar problems according to comments on google. I have a handicapped wife I take care of and having issues with the steering can cause accidents and injuries. There were no messages or symptoms of the problem prior to the failure. There needs to be a recall or further inspection done on the 2011 Mercedes Benz C300. Car will be towed to a Mercedes Benz dealership for diagnostics.

9 Steering problem

Failure Date: 02/01/2023

Electronic steering locks are failing in these cars at an alarming rate. When it fails, the car will be stranded or if driving the car will completely lock the steering and take away control from the driver. This is a safety issue that mercedes should be recalling and fixing because it will take people's lives away. Mercedes is aware of this issue but is failing to recall it and considering it as non-safety. When manufacturing the electronic steering lock, mercedes used cheap parts that are prone to failure. This issue affected many years and models of their cars but only recalled a few cars. Once failure occurs, the car will not start and it will be required to tow it to a dealership where repairs over $2000 will be needed to fix this safety issue.

12 Steering problem

Failure Date: 08/15/2022

08/15/2022 (date statement was wrote not date of incident) while driving into work at 50 miles an hour, traffic started to slow. While applying brake heard loud pop and vehicle rear end lounged right making steering difficult, I immediately released the brake and control came back I then gently applied the brake again to slow vehicle and felt slight clump from rear. This was very disconcerting my vehicle never had performed in that manner which made me feel very uncomfortable continuing driving, I had mechanic look at vehicle and was told the rear subframe had rusted and the rear left control arm broke away from frame??? my vehicle is very well maintain and just a little over 11 years old. Feeling belittled I began investing mercedes’ forums and found this has been an issue with some of not all models and nothing has been done to correct this defect. I contacted mercedes’ benz and the service department knew exactly what it was and stated the is no recall on these failing subframe due to rust. This is a very serious safety issue due to the fact of loosing control of the vehicle when this component fails possibly causing serious injury or even death. To put insult to injury mercedes has no plan to replace it and it’s left to the consumer to replace this non maintenance item. Looking into forums about this issue these subframes have failed at almost every odometer mileages, particularly the w204 chassis 2008-2014. A safety recall should be advised to the consumers whom own such vehicles!! safety first!!!!!!!!! respectfully, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

13 Steering problem

Failure Date: 06/23/2022

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.

14 Steering problem

Failure Date: 06/01/2022

I own a 2011 C300. Recently, my car suddenly stopped working while I was attempting to leave somewhere away from my home. It would not crank or turn over/start. So I was completely stranded, and in the extreme florida heat. There has been no damage or wreck to cause this. There were also no warning lights or symptoms in my car beforehand. My car was towed to a Mercedes Benz dealership in the nearest city. They diagnosed the problem as an electronic steering lock failure. I asked how this happened. I was told that they do not know how it happened. I was also quoted a very expensive repair bill. Upon researching this problem further, I found out that steering lock failure and ignition switch failure is a recurring and common problem that Mercedes Benz already knows about, and many people with my car and similar models have had the same problem over the years. Age of the car at time of failure did not matter, either- it has happened to many cars at different ages and mileage. This is not a normal problem for any car to have, nor is it caused by normal wear and tear. Some people have even had their cars suddenly stop working while they are driving. Many people have also asked why these faulty parts have not been recalled yet. I contacted the company multiple times and did not receive any resolution to the problem. They said that this is my responsibility to repair, and they would not pay to repair this, nor reimburse me. The company's agent did not care at all about the issues, nor take any accountability for them as the manufacturer. Being stranded in the middle of nowhere at any time is dangerous for anyone, especially in certain areas or during intense weather. This entire issue has caused extreme stress for me- interruption in my schedule, lack of transportation, and financial loss. Please hold the Mercedes Benz company accountable for their lack of proper manufacturing and lack of proper repair to their parts that they know are faulty. Thank you.

15 Steering problem

My 2011, 300c has 116,000 miles. Driving the car I notices that when I applied brakes car swayed to the left. Concerned I brought vehicle to mb in paramus, NJ. Was told that rear sub-frame was rusted and dislodged along with the brake lines, also rusted. Car was serviced every 10k miles as recommended by dealer and just now these issues were identified. I recently also was told that the fuel tank was also rusted out and needed to be replaced. These issued were a danger to me and my family and could have resulted in potential deaths. Mb does not have any recalls for these problems but I believe NHTSA should initiate a recall as many others have had these problems. A google search has identifies a large number of people having these same problems. Below are 2 videos of the problem. Https://app. Mykaarma. Com/service-cart/mpi/bfgpb6lkrwayxn3tkqfzqa2mgczxygihmma6ker7cfe/check/your_car_check_id/media/0/view/1 https://api. Mykaarma. Com/video-walkaround/details?inspection_uuid=629e0e431dd41d3dfba54fd1&filetype=video no warnings messages or previous symptoms occurred and even though car was serviced every 10k miles, dealer neve identified any of the concerns. How can that be when brake lines are rusted. Dealer refuses to take any responsibility and mb germany has yet to respond to my various emails. Please review as these issues have life and death implications and a recall should be initiated by NHTSA.

16 Steering problem

Failure Date: 01/02/2022

I haven't had an issue with this yet but have heard others having this issue. Mercedes benz fitted cheap plastic electronic steering lock (esl) in these models that are prone to failure. Unexpectedly, this device will fail and will lock out the steering which can happen anytime and can cause a serious accident. The car will have malfunctioning steering when this device fails and should have a recall.

17 Steering problem

Failure Date: 07/14/2021

2008-2011 mercedes models were manufactured with cheap electronic steering locks that fail often. While I haven’t experienced a failure while driving, the system is and has been extremely problematic and unreliable. It is highly plausible that the system could fail while driving due to the cheap components and unreliable and faulty programming. I urge the NHTSA to look into this and require mercedes to replace these esl’s with a safer, more reliable steering component that doesn’t have the potential to suddenly lock or unlock due to a unforeseen failure.

24 Steering problem

Failure Date: 08/30/2016

The electronic steering lock mechanism on these vehicles appear to fail with alarming frequency. If the failure was to occur any distance from a dealer a motorist would be stranded, perhaps in a dangerous situation. I was lucky - the failure occurred in my home town, but the nearest dealer is 2 hours away - they are the only ones who can fix it. This situation is dangerous and the failure to address it (by Mercedes Benz) irresponsible.

27 Steering problem

Failure Date: 08/12/2015

This is a well documented accident as it involved a police chase of a felon who ran a red light at approximately 50 mph. My car was hit on the left front side and is deemed totaled. No air bags deployed in my vehicle and I required emergency transport to the local hospital emergency room. This also involved a police shooting incident with the death of the other driver. The vehicle is pending towing to a salvage yard. The primary concern is a question of defective air bag deployment and future potential injury to others.
