One problem related to dashboard failed has been reported for the 2010 Mercedes Benz C300. The most recently reported issues are listed below.
Similar to other complaints that have been filed against mercedes, it seems as though the electrical connection to my rear right light (brake light, running light, turn signal, etc. ) has melted and is no longer operational. The entire light is out and I get warning messages on the dash about the problem. It looks like this is the same problem that everyone else with the same make/model as me are having. Hopefully mercedes recognizes the scale of this flaw in their engineering and sends out a recall sooner than later.
