Warning message displayed in instrument panel advising to check rear right hand side marker lights, on initial inspection in the truck their was a smell of burning plastic emigrating from the right hand side rear light cluster on removal of the fuse panel cover and inspection the wires which connect the wiring harness to the lighting backplatei I was unable to hold the connector with a naked hand due to the excessive temperature. After leaving things to cool down for 60 minutes I was able to remove the wiring harness connector from lighting cluster back plate to find that the earth pin (brown wire extreme right hand side ) was melted and also the pin to which it mated too had also began to melt the plastic which supported the pin on he lighting back plate. The earth (brown wire) is of an extremely low gauge for the potential load this wire would potentially need to carry under maximum load (all lights lit).

My right rear tail lamp was malfunctioning. The directional was blinking rapidly. The malfunction required the removal and replacement of the right rear bulb carrier. The car was no longer on warranty and I had to pay for the repair out of pocket. I understand that tail light failure is a common problem with this model and year, usually caused by wiring defect. The dealer never informed me that this was a common occurrence in this model. I had similar problems prior to the malfunction however they were covered under warranty.

Started to get the message to check my rear, right turninf signa, fog lamps, brake lights. Checked all the bulbs and they are fine. Put the harness back and realized it was a little hot and when I looked the wire to the far right I think is expose and on the other side it is burnt through the plastic. Message comes off and on during driving.

problem #46

  • 80,000 miles


Was pulled over by police who informed my taillight was not working on my passenger side. When pulled over, taillight illuminated but very dimly. Issue has been going on since roughly June 2012 when purchased. Was not disclosed that this was a possible issue at time of purchase and did not discover the issue with melting of wiring harness to light panel until checked 11-8-13. Took to local dealer who sold me the vehicle, and Mercedes is planning on charging me $305 for repair (parts roughly $50). This is unacceptable for a known deficiency with the vehicle. This should be a recall item without a doubt. I will be mentioning this ongoing investigation to the Mercedes service people (as if they don't already know) and attempt to get them to fix at no cost.

C300 6-cyl

  • 63,500 miles
Rear tail lights malfunction. Ground wire in the tail light harness gets very hot to the point of melting the insulator on the wire and rear light connector (which provides power to the tail light). This resulted in the rear tail lights to stop working. This is a safety hazard and needs to be addressed. Mercedes will replace the parts if the car is under warranty but will not cover the repair out of warranty. Furthermore, the replacement parts are the same and this issue will reoccur.

My right passenger side tail light connector board is melted. All my lights stopped working at once and dealer stated its a faulty connector board that needs to be replaced. Same issue so many others have reported. Mb needs to recall this issue bc it makes no since I have to pay $400 for a well known issue that is hazardous which the dealer advised.

As reported multiple times by others, tail light connector is insufficient to handle the heat emanating from the ground (brown) wire. Connector burns. Cable covering melts. All tail lights (including brakes, turning and reverse) stop functioning. - safety issue- (not to mention gas tank sitting not too far from source of fire) preliminary symptoms: Random warning messages in dashboard about lights malfunctioning. One tail light dimmer than the other. Repairs required: New connector/new pins plus regrounding to avoid certain recurrence authorized dealers know well about the problem. "recall should be issued" "recall is surely coming" but will not replace if out of warranty references: Prior report chain NHTSA id number: 10499828 pictures and multiple information
