Four problems related to wiring have been reported for the 2008 Mercedes Benz C350. The most recently reported issues are listed below.
The brake light (driver side) was malfunctioning and giving multiple indicator warnings on the dash computer. After checking to see if it was a faulty bulb. . . The harness connecting to the taillight housing was burnt and melted. The taillight bulb housing was brittle and was burnt as well. The dealership said they know of no such recalls and are replacing the taillight bulb housing and replacing the burnt harness. (435. 00) they also said that the computer module is bad because it is telling the brake light to stay on. They are not sure which occurred first. This is another 1000. 00 repair. I have researched this issue online and there are many other mercedes c-series vehicles having the same issue. Most experts think the gauge of the wiring is not acceptable to the load of current. This is a safety hazard and is not looking like an isolated incident. Thank you for your support on this matter.
Rear drivers side and passenger side tail lights (brake lights, turn signals, and running lights) are no longer functioning. Upon inspection, lights are barely functioning or not functioning at all with no indication of faulty bulbs or fuses, and wiring harness connecting the tail lights to the electrical system is extremely hot.
The contact owns a 2008 Mercedes Benz C350. The contact stated that the instrument panel caught on fire. The contact took the vehicle to the dealer where it was determined that the radio and the wiring needed to be replaced. The failure and current mileages were 109,000.
An error message was displayed after driving a short distance. The error indicated a failure in the left tail light and a burning smell. On investigation I found a burned area of the tail light assembly ground wire connector. I replaced the bulb holder and wiring connector. This did not fix the problem. On further investigation I found that the same issue was present on the right side tail light. I also found that most of the light bulbs on each side were very dim. This car is unsafe to drive in its current condition. The local mercedes dealer stated they were not aware of any known issue with the tail lights at the time I bought the replacement parts.
