I received a warning on my dashboard that my right rear tail light, right turn signal and back light needed to be checked and malfunctioning. The message came and went for several days. When I opened the compartment where the tail bulb carriers and assembly were, I saw that some of the lights were very dim. The carrier itself was piping hot. So my first reaction was to replace the bulbs. I did. Same problems, nothing was fixed. The next day, everything cleared up...so I thought it might be fine. A week later, it came back. When I opened up the compartment again, it was super hot, and I noticed that the wiring was browning and it burnt my finger. I immediately stopped driving the car. I went to the dealership and they said it will cost hundreds to replace and not covered.

I received a message to check the rear right (passenger) lights and turn signal. I just purchased the car used on may 20, 2014, and began getting the dashboard warning a few days later, but it was intermittent. On may 26, 2014, I inspected of the bulb carrier and pin connector and noticed that the connection involving the brown wire on the pin connector was burned and the corresponding connection on the bulb carrier was also burned/disintegrated and the area around the brown wire was very hot. It is difficult to know when the failure actually happened.
I was driving the vehicle and a message light came on saying check rear right brake lamp, turn lamp ,and tail lamp so I stopped by the auto part store to have them replace the bulbs and they found the light holder and the wiring harness to the lights had melted.
Right rear passenger lighting assembly caught fire. Wiring harness and light bulb carrier were burned. Right rear turn and brake lights are inoperable.
Right rear taillight pig tail overheated and shorted out lamp holder. You can see the burn marks where it was too hot. Has to be replaced.
My exterior tail lights all went out, this includes fog lights, tail lights and indicator lights. Put in new bulbs as well as made sure the wires were connected well but it remains out.
March 1 2014 I notice my wife dash was lighting up with rear brake lights needed to be replaced. I opened the trunk and hit the brake compartment and it came back on. April 11 2014 the light came back on and I tried doing the same thing but nothing. Opened the brake compartment and disconnected everything on that side awaiting a response from the dealership. Don't want another melt down back there in the trunk. If this is the best company out there just announce a recall and fix your customers faulty equipment.
The dash warned me that my rear tail lights were malfunctioning. The message came and went for several days until it was on continuously. I accessed the electrical compartment and the ground side of plug, the socket and the wire was melted and has been on fire. I have pictures on dropbox: link attached https://www.dropbox.com/sc/w4tm7b28phh9lal/-dz3htmls-.
Rear lighting does not always work, I have gotten error codes one day and the lights work the next. I have read plenty of complaints on the lighting issue. One time its a bulb on the right and next its a bulb on the left. Today they all work..
Components of the tail light assembly on the driver and passenger sides have overheated and rendered the units inoperative. As a result, the tail lights no longer work. This seems to be a known issue and common occurrence in aging assemblies of this type.
There seems to be a light shortage on the right side, the right turn signal doesn't work properly. The lights work , the issue is the panel and the wire is now melted at the tip. The wire melted into the light panel.
The driver side tail light housing has burnt out and knocked out all lights in the cluster. This seems to be a known issue, but there has yet to be a recall for this.
Wiring harness on rear tail light melted causing the tail light circuit board to stop working ,causing the brake lights ,reverse lights and blinker to stop working.spoke with mercedes benz dealer ship and they told me this was a common problem and that they were not gonna fix it for free and that I would have to pay for the repairs.this is a hazard cause I was driving at night with my kids in the car,when my lights went out.after looking at the melted harness wire this is also a potential fire hazard. Please look into this matter before some one is seriously injured. Mercedes benz is aware of the problem and refuses to correct it....
I was driving down the highway and smelled an intense burning. I had been getting the taillight error codes and thought maybe it was a fuse. Decided to finally research online and discovered that it is a very common occurrence that mercedes taillights/wiring spontaneously catch on fire. I removed the harnesses from the taillights and noticed the plug had almost been entirely destroyed/burned on the right rear, and was starting to burn on the left rear. I lost all power to my taillights at approximately 11:30 at night, and the headlights started shutting off and on randomly. The headlights are still turning off and on randomly, apparently this is a known defect with the auto dim setting. I have pictures of everything, even though I have now paid to fix the taillight harnesses (a cost of over $240 in parts) because mercedes has not willingly recalled this fire hazard and known defect. To be honest, I am pissed. Please let me know where I can send the defective parts and/or pictures to.
All rear tail lights stop workingi replaced the lights. Mercedes dealership said the wires had fried and that they had seen many cases similar to the rear lights. $600 to correct the issue.
The tail light completely melted the circut board and stopped working.
The lamp connector on the rear right side of the light component went out, when I went to look at it, I noticed the connecter plug in as well as the light circuit board was burnt and would not be plugged back in.
Warning message that the back tail lights & signal lights were out. After check it appeared that the wire had melted.
Rear brake lights are staying on while driving the car and the parking lamps both went out. The brake lights off when car is off but while I'm driving they stay on the whole time. I took it to ray catena mercedes auto service and they advised me that they needed to replace the wiring harness no charge as part of a recall on all mercedes vehicles but gave me a quote of 1175 for the module. I was told that the module shortage and lights going out is most likely due to the wiring harness frying out. I shouldn't have to pay to replace a module that was due to a wiring harness frying out. That should be a manufacturer issue.
All rear tail lights stop working, some in the front not working, electrical wires were burnt I replaced the lights, the dashboard alert went away then came back on 10 minutes later. Also tire pressure monitor inoperative on dashboard alert as well. My friend with a 2008 c300 has the same issues with hers too.
Light warning lights came on dashboard for rear light and turn signal. After looking @ the connecter found it smoking and melted ... Immediately unplugged it. Mb does not have a recall even though you are investigating .
All the lights outside of the car are going out. The entire rear left light is not working, along with front head lights. They have been replaced and I keep receiving messages on the dashboard. It was taken to the dealer and there is corrosion on the wires.
Entire tail light on drive side went out. I looked at the lighting housing and noted burnt wires emitting from the housing.
While driving home from work, I was receiving error messages on my instrument cluster asking me to check the rear passenger brake lights and turning signal bulbs. Once I was home, I opened my trunk and smelt burning plastic. I opened the access panel to the fuse box located near the passenger taillight and inspected the area for damage. I noticed some residual smoke coming from the connector attached to the taillight bulb assembly. I removed the bulb assembly and the brown ground wire had burned through the plastic assembly. I removed the wire harness from the assembly and the connector crumbled due to the damage.
I received a warning that my left tail light was out. The light was not out and when the car was restarted the message no longer appeared. I went to the dealership and asked service to check the taillight. The service manager showed me the light panel which had melted plastic and burn marks on it near the grounding wire. He told me I needed to have it replaced as well as the circuit board. I told him I thought it was ridiculous to have electrical problems with a car with 85k miles. I just replaced an electrical panel in the front 2 months ago for $700. I asked if they had problems with the c and he said no but he had seen a few issues with the grounding wire. I just looked into it to discover it is under the federal safety agency investigation. Please advise.
Right tail light cluster had a electrical short in the lamp connector, which ultimately had to pay $250 to replace in mid december 2013. Now it seems that I am having the same issue on the left side. This is a safety issue and needs to be addressed.
Right rear taillight assembly completely went out as a result of a bad ground wire. On that side there was no brake light, no turn signal, no running lights, etc. After inspection the ground (brown outer most wire) where it connects to the plug/rear tail light assembly has burn marks and corrosion. I used electrical tape to tape up the exposed wire (due to heat/sparks the insulation on the wire was gone). Currently, all functions of the tail light are dim ( 75% dimmer than the other side) and at times it just completely doesn't work. I have stopped driving the car as a result of this as I do not feel safe driving as I fear it might lead to a small fire.
Tl* the contact owns a 2009 mercedes benz c300. The contact stated that the front driver's side headlight, rear driver's side brake light and the turn signals failed. The local mechanic replaced the bulb however the wires overheated and melted, causing the light bulb and assembly to become damaged. The vehicle was not repaired. The failure mileage was 74,000 and the current mileage was 93,505.
Tail light problems. I started receiving warning messages regarding the tail light malfunction. We checked the lights but they were fine. In january the light went out. I took my car in for an oil change and was told that the bulbs were not only out but the cause was due to a circuit issue. After picking up my car, there was an additional warning for my sidemark light.
Approximately 1 year ago, the back (driver-side) tail lights were malfunctioning and I had to replace the bulb. I did mention this to the mercedes dealership when I went to service another issue, but they stated there was no issues, just a bad bulb. Unfortunately this happened a few times before a service tech noticed that the back board was "fried" and suggested I go to a mercedes dealership to get it repaired. Not only am I past the 5yr, 50,000 mile warranty, so mercedes will not cover the costs, but the dealership has had my car for 3 days and cannot determine how to repair the issue. They replaced the board, but they are now stating that they may need to replace all of the wires. I called mercedes to complain, but without a recall in place, they will not cover the costs to repair.
