Right rear tail lamp assembly. Lights appeared dim for a couple months and figured lights were about it go out. Went to buy new light bulbs to replace the dimming bulbs and when I opened the right side to install the light I noticed the electrical cord attached to the assembly had melted. Lights were still dim and checked to see what it sounded like when I turned the lights on and it makes a crackling electrical sound. I assume that's why it smelt like something was burning and why the 8 prong piece melted. 1-6 on the electrical piece look good. 7 is damaged due to number 8 completely melting off.

C300 failed to start. The ignition seem to work correctly.the engine would start and cut off immediately. After several tries, finally the car started and I was able to drive it to the dealer. The dealer was able to replicate the issue. The service manager said it was probably computer and a full reset will fix the issue. I got the car back a week later. While driving back home, I stopped to get gas. I turned of the car and after pumping the gas, it refused to start again. I had to call the road side assistance. The car is back at the dealer now for 7 weeks. I also have a case open with Mercedes Benz. So far there is no response as to what may be causing the issue.

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.
