2008 Mercedes Benz C300 lights complaints

After taking my care to the dealer, I had a error message on my display stating that my right rear tail light is out. Then a message stating my right low beam is out. I replaced all the bulbs..... Five days later I get another right rear tail light is out. Two weeks later my right low beam is out again. Seems there is a wiring short that keeps burning out the low beam and tail light. Oh by the way tail light/brake lights work. Still have error message.
Passenger tail wire harness has melted to the connector and the lamp holder. This is because the connector pins used for the ground wire cannot simply handle the load. I am not sure how the passed the mb quality control. This could easily be a fire hazard. Mb dealership recommended the same pin connector to fix but I'm sure this will happen again. I am filing this incase my car burns because of the issue.
I received messages on my dash stating to check rear left turn signal and rear left tail/brake lamps. Upon pulling out the rear left (driver's side) tail light assembly, which holds all the bulbs, I noticed that the tail lights would flash when I jiggled the wires but not stay on. I pulled the harness plug from the socket on the assembly holding the bulbs and noticed a blackened burnt spot and melted plastic on the plug itself, and also a burnt spot inside the plug socket which almost burned through the other side of the tail light assembly unit. I have pictures of both the tail light assembly unit plug and socket showing the burned markings. This is a very concerning electrical safety hazard that could lead to a fire. This issue seems to be similar to 2 other incidents reported in the federal safety agency database for the mercedes benz c300 2008 model year (incident #s 10475771 and 10466181).
The tail lights of my mercedes benz c300 2008 stopped working. When I went to my local mercedes dealer to see what is wrong with the car, the service person at the dealership immediately told me that they were fully aware what was wrong with the car without even looking at it. They said that the plastic covers of both real tail lights along with the wire harness had melted. In fact, the service person put his hand back there and he got burned because the entire wire assembly was melted and was short. I asked them to repair the car for free because this is a defect since the wire harness assemblies and plastic tail cover lights should not melt under any conditions. This is both a collision hazard and a fire hazard and it is very common in this model. Mercedes benz USA refused to fix the vehicle for free as they have an obligation to do since this is a defect. Please issue a recall for the plastic cover and wire harness of the real tail lights of this vehicle because this situation is dangerous both in terms of a fire hazard and in terms of a collision hazard.
On or around 8/30/12 I noticed I had no rear brake lights. Thinking a bad bulb I checked the rear taillight bulbs. I noticed an overheat condition on the bulb holder and connector. It is melted showing extreme heat and current draw. I contacted the dealer expecting it to be covered under warranty as it is a defect and unsafe. They would not cover it under warranty and gave me an estimate of over $400.00 or more. This is a safety issue and a design flaw and should be mercedes' responsibility. Who is liable if I get rear ended or if the vehicle catches fire? *tr updated 3/28/13 *cn updated 3/29/2013 *js...updated 05/08/13 *bf updated 05/20/13
Both right and left rear tail lights malfunctioned. First, I noticed that one or the other of the right side turn signals failed to function because I heard a rapid clicking as I made a right turn into a parking lot. Once stopped, I noticed that the mercedes command system said to check the left rear tail and brake light bulbs. I saw no mention of the right turn signal. When I left the parking lot an hour later, there was no indication on the command system as to anything being wrong. At home, I removed the left printed circuit board and saw that the tail light/brake light bulbs were very dark and gave the appearance of having failed. On testing them with an ohmmeter, I discovered that they in fact had not failed. Even so I wanted to replace them, and on the 10th, which turns out to be 1 day after my 4 year warranty expired, I went by the dealership and the service rep gave me two replacement bulbs. I changed out the old bulbs and all appeared okay. However, the next time I drove the car long enough to get it thoroughly warmed up, I got indications from the command system that not only had a left brake light failed but also the right rear turn signal and also a right side marker. I removed the right rear tail light circuit board and found a burned wire and burned spot on the board itself. I saw nothing on the left rear board. On the 13th, I considered having the car towed to the dealership but decided to drive it. Standing outside the car I saw that the right rear turn signal wasn't working at times, but the rear brake lights appeared to function. In summary, there appeared to be a malfunction in one or both tail light assemblies that occurred due to heat. The dealer replaced the printed circuit board on the right and made other necessary and returned the car in what appears to be good condition. My cost was 50% of the total.
Turn signals and wipers / windshield washers cease to operate until car is restarted. Wipers continue to operate in rain sensing mode but not via the wiper control level. Dealer was not able to find any diagnostic codes afterward. Failure recurred a few days after dealer inspection, and occurs sporadically both in urban and highway driving. Time between failure ranges from hours to multiple months.
