| Description of the problem | 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 .
