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 the federal safety agency 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.

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.

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.

Parked the car, did something, came back and car did not start. Key in, no crank, no start, no steering. No lights on the dash, no gear shifting, can’t roll the windows up. All out of nowhere. Think it’s a problem with the Electronic Steering Lock.

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.
