Car Will Not Start problems of the 2014 Mercedes Benz C300

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.
