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.

I was stopped in front of my garage (waiting for the door to go up). When I lightly pressed on the gas pedal to pull in, the engine roared and the car suddenly leaped forward at a very high rate of speed, going thru my detached garage wall. The accelerator pedal stuck and I could not get the car to stop. I have pulled into this garage thousands of times and knew this was the car. Slamming on the brakes could not stop the car because it was accelerating too quickly. Hitting the brick facade of the condominium, beyond the detached garage was the only thing that stopped the car. No airbags deployed, which I thought they should have because of the impact. Even though I only traveled approximately 30 feet, the car accelerated so quickly, it totaled the car. The car is currently under recall as of November 2017, for a steering column issue, which includes improperly grounded components and the steering column clock spring being broken issue related to the airbags deploying while driving the car. I have tired several times to have the car repaired and have been told the Mercedes dealership still does not have the part. Per the dealership and Mercedes, I was adviced I would receive a letter when it was available. I purchased the car used and have since found out since this is the third recall on this vehicle. I believe it had to be something with either the accelerator automatically engaging. It was almost like the cruise control quicked in. Since it is under recall for the steering wheel related issue, I don't know if it affected the cruise control and caused this to happen.
