One problem related to wiring has been reported for the 2015 Mercedes Benz C250. The most recently reported issues are listed below.
Area under steering column is exposed revealing electrical wiring which appears to be connected to the engine or something under the hood. I was told that's the way vehicle was made, no part or option to cover exposed area. It is unsafe because as I am driving on highway, city streets, etc. , my knees touch the area and may jarr something lose.
