This data is from the NHTSA — the US gov't agency tasked with vehicle safety. Complaints are spread across multiple & redundant categories, & are not organized by problem.
So how do you find out what problems are occurring? For this NHTSA complaint data, the only way is to read through the comments below. Any duplicates or errors? It's not us.
The contact owns a 2008 Mercedes C- class. The contact stated that the rear tail lights failed. The contact took the vehicle to the dealer to have the light bulbs changed and the dealer advised that the wiring harness failed. The vehicle was not repaired. The VIN was not available. The current mileage was 62,000 and the failure mileage was unknown.
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.
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 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? updated 3/28/13 updated 3/29/2013...updated 05/08/13 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.
