Yesterday (10/27/2013) I had to change out my rear right side brake lamp, which I successfully did right after I saw the message pop up on my dashboard. Then today (10/28/2013) in the afternoon I turned on my car and all these messages popped up regarding my right side turn signal, right side reverse light, right side fog light and the other bulbs in the right side bulb housing. I then opened my trunk and checked it out, and noticed that the far left side wire of the connector connecting to the bulb housing was burned luckily it did not catch on fire. I tried to take it off but was not able to at the moment, but I was able to take it out after a couple of hours. There was a horrible smell coming from it and I tried to clean out all the gunk in the connector but was not able to. Please get this issue fixed and call out a recall before someone doesn't act fast enough and leaves the connector plugged in and causes it to catch on fire.

Received a message that rear left brake light, fog light, turn signal were out. Turns out the wire that goes into the harness has melted and shorted out. The same thing happened two months later with the rear right light assembly. This is a huge safety concern.

A message on the dash consistently appeared, advising to check right rear lights: brake, fog, tail etc. We checked the rear lights and found the plastic board that holds the light bulbs and wiring had melted. We purchased a new board from a mercedes dealer. After I installed it, it made good connections. The message concerning the right light has not come back on. However, the left brake, fog and tail message came on. When checked, the left board and wiring was also melted. We purchased another new board from mercedes. However, I was able to reestablish a connection using the old board, and did not use the new board. Now the right front fog light has a similar issue that has not been investigated or repaired.

My car computer was showing a message that the right rear signal light, fog light needed to be checked. My husband changed the bulbs and the message was still there. These lights were no longer operating properly. Took the car for scheduled service and brought this to the attention of the mechanic at a Mercedes Benz dealer/auto service. He told my daughter that he removed the access panel and found that the connector to a bulb carrier, wire harness and bulb carrier were melted due to a short at the ground wire of the 7 pin connector. I called the service mgr he could not tell me or explain why this happened or its cause. Disappointed by his lack of knowledge and explanation of the cause, I contacted mbusa. At first the person that answered tried to brush me off " this can happen". When I insisted for a better answer or explanation she referred me to a "[xxx]"1-800-367-6372 ext. [xxx]. Who stated that she would speak to other technical people and get back to me. When she got back to me, it was basically she was going to speak to the service mgr. At the dealership that serviced my car. He called me on 2/01/12 not clarifying the cause,just re-iterated what he had previously stated. I call [xxx] who simply stated that this has never been reported before, but it can happen, and stated that the dealership would give me a $200. 00 discount at the next service date. I wanted an explanation of the cause, could this happen again, could this lead to further melting, that could lead to a fire, a bigger shortage, and possible accident. I was told by the mgr. At dealership, he cannot foresee the future and he could not predict if this would happen again. I was told that a defective part is not a major issue. No one offered to look further into the defective part and try and find out what really happen. If a part is defective, it should be evaluated or even ask for the part .

There is no failure of the vehicle but it is a safety issue. Fog light lens that is made of glass has no safety barriers to protect it from breakage and it is mounted very low. With the crack of the lens, the fog light needs to be changed and the cost to change is it $248. Mercedes is refusing to accept it as a design defect. If I do not change this due to cost, it is a big hazard especially for owners living in fog prone areas like san francisco bay area where I live. If not changed, there are chances of accident on the road during fog days. Mercedes has changed the design of the fog lights in the following years (after 2009) of C300. Mercedes should change this defective design and fix it for free for 2009 year as well for free. Even after I pay $248 to get the light changed myself, it will crack again since it is made of glass and not covered by any protective barrier. So, even after paying to get the fog light replaced is not going to fix the design defect.
