The electronic steering lock (ESL) system on my 2014 Mercedes-Benz C250 failed without warning, leaving the vehicle completely unable to start. When attempting to start the vehicle, the key would insert but the vehicle would not crank or start, and the steering lock malfunction prevented normal operation of the vehicle. The vehicle became stranded and inoperable. This failure created a safety risk because the vehicle could not be moved and left me stranded unexpectedly. If this failure were to occur in an unsafe area or emergency situation, it could place the driver and passengers at risk. After researching the issue, I found numerous reports online from other owners of similar Mercedes-Benz C-Class models experiencing the same ESL/EIS failure. This appears to be a common issue affecting these vehicles. At this time, the problem has not yet been repaired. UNKNOWN if the manufacturer has inspected the vehicle. No warning lights or prior symptoms appeared before the failure. The malfunction happened suddenly and without warning.

Service BrakesSep 2025 · ODI 11690125Details +

I was coming off the freeway on 9/25/25, and when I pressed on the breaks they completely locked up and would not break at all. The car turned off, no warning lights nothing, and I continued to hit the break and the car would not stop, then all of a sudden it came to a stop almost colliding within inches of hitting the Semi-Truck in front of me. This is the second time in one year that this has happened to me, I have had the car checked out the first time last year immediately, and even paid to diagnose it, nothing, I had the brakes and rotors replaced last June of 2024 when this happened. Since then the car has only been in the dealership to get the car Fully checked out mutltiple times within 2024, 2025 and repaired by Mercedes dealership. On 9/25/25 this happened to me and it was a traumatic experiance when I pressed the break and the break got super hard and in a Locked position and would not come to a stop, there was no warning lights, no engine lights, nothing. (increased braking effort, and potentially I was inches of collision risk. I had the car towed to the nearest shop and was told this is a collapsed break booster Vacuum pump, and possibly the hose and lines and possibly further problems but they would need to replace the Vacuum pump first. After I looked to see if there was a recall on the vacuum pumps in that model on google and it says the following; Google- 2014 Mercedes c250 recall on Vacuum pump A-Premium Vacuum Pump Compatible With Select Mercedes ...Yes, there was a recall on certain Mercedes-Benz vehicles, including some 2014 C250 models, related to a defective brake booster vacuum hose. The recall involves hoses that may delaminate over time, leading to a loss of vacuum, increased braking effort, and potentially a collision risk. To check if your specific 2014 C250 is affected by this recall, you should contact an authorized Mercedes-Benz dealer or visit the Mercedes-Benz USA website to check for open recalls for your vehicle's VIN.

SteeringSep 2025 · ODI 11688424Details +

The "ESL Module" in this model is designed to unlock the steering and ignition when the vehicle key's passcode matches, using a small, mechanical motor with significantly poor durability. The problem is that this motor's failure is unpredictable, and many users of this model have been stranded and unable to start their vehicles due to the motor's lifespan ending. Even when the car is painstakingly brought to a dealership, repairs cost approximately $1,800 to $2,000, or owners are resorting to unofficial bypasses using a device called an ESL Emulator from the aftermarket. I'd like to request NHTSA to start a thorough investigation into this issue and a RECALL order for the affected models to be issued to MBUSA. Thank you.

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. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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. MBUSA Campaign Number 2017120024 NHTSA Recall Number 17V627 Recall Start Date January 18, 2018 Recall Reported Date October 16, 2017 Component(s) 1709P46C62 Daimler AG (DAG), the manufacturer of Mercedes-Benz vehicles, has determined that certain MY12-17 C-Class, E-Class, E-Class Coupe vehicles (204, 207, 212 platform) have insufficient electrical grounding in the steering column components. In rare instances, if the steering column module is exposed to an electrostatic discharge, and if the steering column module clock spring is broken (due to wear), this could lead to an inadvertent deployment of the driver airbag. An inadvertent driver airbag deployment may cause a risk of injury to the driver and might increase the risk of a potential crash. A broken clock spring will illuminate the SRS warning light as well as display a warning message in the instrument cluster. An authorized Mercedes-Benz Dealer will install a sufficient ground to the steering column, and a protective ring to the steering column module.

Driving on [XXX] to Atlanta GA my car would not automatically shift and began to vibrate badly. I was almost hit by other vehicles as I pulled off the highway to check car out. Car was vibrating badly in idle and when I resumed my trip back home the car would not accelerate properly and caused tremendous stress and danger. Figured out that car would not shift automatically and I was forced to shift the car manually. Car would sputter and vibrate badly and would only slightly less vibrate to where I could drive it home in gear D5 and would less vibrate at 75+ mph very dangerous, and would lose power and shake violently going up highway hills. I prayed all the way home and barely made it shaken. I called my Mercedes Benz Dealer from the highway and immediately scheduled appointment on 8/15/24.

I was driving on the highway my car sort of hesitated for a brief second then continued on as if nothing about one mile later my car began to slow down while I was in traffic so asap I pulled over at this point I could only go about 40 miles per hour which was very terrifying at that time it came a complete stop. After restarting the car 3-4 times it stayed running I continue home which was about 12 miles from my current location. For the next few days I did not go any where. I then had an appointment to have the 80,000 mile maintenance I mentioned the problem I was then told I need a throttle body replacement costing more than $2000 that I can not afford. At that time I started researching my own problem. My relative who works on 18 wheel truck for a living, . that perhaps it just may need cleaning rather than replacement . Also per my research this happens quite often with this model it also stated that Mercedes C250 was the worst Mercedes of that year many many owners have had this problem. The yellow ESP light come on saying it is off also my hold brake no longer works. It work at my prior dealer appointment it while going to appointment afterwards it did not work since over 9 years seldom used I wasn't concerned thus that is the message that appears when car fails Mercedes wants me to pay I believe $2000 problem not needed

I bought my 2014 C250 back in 2017 with 17K miles and currently has 58,570 miles. The issue is with fast acceleration from a stop or slow moving. When trying to accelerate to merge with traffic after a few seconds the vehicle goes into limp mode and the check engine light comes on. In limp mode I am only able to accelerate very slowly and this is a major concern for my safety. This has been and ongoing issue over the past few years and I have learned to reset it temporarily (around 10 times) with a YouTube fix. I recently found out that there was a recall for the high pressure fuels pump on some C250 models but mine was never included. I also found out that the recall time limit has expired. Please investigate and expand the recall along with the time limit so my vehicle will be included.

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.

The passenger airbag was replaced under the Takata recall. Recently the airbag indicator light came on for the driver airbag. We have been notified by the dealership that this airbag needs replaced. They provided an estimate of $2,652.29. We reached out to Mercedes due to this being a safety issue and also due to the fact that the passenger airbag was replaced under a recall. They are unwilling to assist. It is illogical that just the passenger airbag is faulty in the recall but that the driver's airbag is fine as they came from the same manufacturer and installed when the vehicle was built. We are concerned about either deploying on its own or if it will deploy in an accident.

I prchased used with no visible damage to the windshield. In the inclement weather for no apparent reason my windshield began to crack as I was driving the vehicle. I pulled over as soon as I could. The crack stoped and I called the Mercedes Benz manufacture to no avail. I decided to research to see if this is common and the article says, "that the 2014 Mercedes Benz" windshields are known to crack in extrem cold and hot conditions. The windshield has continued to spider and crack in different direction. I feel threathened at this point and featful for my life that this will implode in my face while driving. I did in good faith reach out to someone.

Power TrainSep 2023 · ODI 11546837Details +

I was driving my vehicle when the transmission started shifting erratically. The shifts were not smooth but hard and the car was shuddering. Yes the vehicle is available for inspection. My safety and the safety of others were at risk due to the erratic behavior of the vehicle and how it affected my ability to focus on driving safely. Yes my vehicle has been inspected by the manufacturer and the problem has been reproduced by my local Mercedes Benz dealer. There were no warning lamps or messages prior to the failure. After a few weeks of driving I saw a “low coolant” warning appear, this turned out to indicate that the radiator had leaked coolant into the transmission which damaged the internal transmission components and torque converter.

SteeringSep 2023 · ODI 11545542Details +

Mercedes has a convenience easy enter/exit feature that lifts the steering and slides the driver's seat back for easy exit and restores the seat and steering when the driver sits down and places the key in the ignition. The safety issue is the steering often gets locked in the up position and doesn't lower, making it unsafe to drive the car. This is happened 5 times since I bought the car. I had to drive home with the steering wheel locked above the dashboard. The car has been towed to the dealership 4 times under warranty and now I have to get it towed myself. There are approximately 54000 miles on the car.

I was in an accident that caused my car to be a total loss. I was hit near the front left side, close to the driver's door. The airbag did not deploy despite the hard impact. I am currently having to go to therapy due to impact. My right lower arm was bruised from the impact, and I was in a lot of pain due to the bruising caused. I am assuming the bruising came from the hit to the steering wheel. I was never notified of an airbag recall.

Car would just shut down intermittently, sometimes sudden death. No crank no start. Been stranded at night alone with my child in the car and at times, unsafe areas. Electronic Ignition Switch is faulty and MB has had my car for 1 month to date. Quoted me a repair cost of $2,787. Said the EIS is on back order with no ETA, and they currently have 5 others with exact problem, ignition switch. So many people have reported this problem for years with the C300. I'm a single mom, it's been a nightmare.
