What owners say
While driving the car on [XXX] at 9pm on sunday, [XXX] in lane two during a heavy rain a audible clicking noise came from the drivers side front of the dash instrument cluster area and all of the lights on the car simultaneously turned off without ever touching the light switch i was unable to see the road in front of the vehicle also the windshield wipers quit working and the radio and navigation display went off and closed and opened and closed( turned off and then on and off again) the instrument cluster went dark as well, luckily i was able to turn the steering and apply the brakes and steer the vehicle onto the shoulder of the road and come to a complete stop after several attempts to turn the headlights back on i determined that the vehicle was not safe to drive , and had the vehicle towed to a reputable mechanic, and upon diagnosis he contacted me and stated that the drivers side front signal acquisition module A. K. A. the (sam) module had failed due to water intrusion into the fuse panel sam module area , the mechanic stated that i should file an incident /complaint form with your office , upon searching the MERCEDES BENZ forums and sites on the www i found many customers with a broad range of models (w204)approximately this same year model have identical complaints and nothing has been done by MB usa to remedy the problem, i believe this matter to be a major safety concern and i am wondering why this matter hasnt been taken into consideration by your agency and by MB usa as a safety recall to replace the failing modules and retrofit the fuse panel sam module area to prevent water intrusion thats causing the obvious safety concern and possible liability on the part of the MB/ DAIMLER corporation. it seems this is clearly a problem and it needs fixed we are terrified to drive the vehicle for fear of a repeat incident. Sincerely the [XXX] family INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
Headlight harness on drivers and passenger side is melting and my lights are flickering. I was advised to night drive my vehicle at night, because it could start an electrical fire. This is caused by heat from the lights.
The contact owns a 2008 Mercedes-Benz C300. The contact stated after the vehicle was taken to the dealer for an unknown recall repair, the air bag warning light remained illuminated. The contact also became aware that the driver’s side headlight was inoperable. The vehicle was taken back to the dealer where it was diagnosed with a detached headlamp wiring harness. The dealer recommended that driver’s and passenger’s side headlamps be replaced. Additionally, the taillights remained illuminated after turning off the vehicle. The vehicle was not repaired. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was unknown.
While driving and when parked the headlights flicker on and off. I have no headlights while driving at night, during adverse weather conditions and during dawn hours. I could crash into other drivers, or they could crash into me because they can’t see me. When a parking bulb blows it fuses and melts everything together causing the replacement of the entire headlight unit, this has happened twice.
Both headlights wiring harnesses (right and left ) wiring has melted and all wiring is now exposed and touching and causing all light bulbs ( headlights-tail lights-turn signals-brake lights-ect) to be shortage out due to the original wiring not being constructed to resist the heat from the engine and environment.We had MB of Maidland,fl and Elite motors of Ococee,fl to view this issue with the only fix is out-of-pocket repair in the thousands of dollars.i have a neighbor with a MB experiencing similar problems
The contact owns a 2008 Mercedes-Benz C300. The contact stated that the exterior headlights and taillights would independently illuminate while idle without warning.

While the contact stated that the failure was intermittent, the failure had become more frequent recently. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 100,000.
My vehicle continuously gives me warning/alert messages of headlight/signal/parking lamp issues. Upon inspection and taken to certified, reliable mercedes repair shops, lights are fully functioning, yet alerts continue on my display/dash. More importantly the electronic steering lock (esl) has failed on more than once costing very considrable amounts of repair bills, and it has happened without warning, I parked the car which has been perfectly maintained and with low mileage, and the steering wheel locks, making it almost impossible to even have it towed to be repaired.
I purchased this vehicle in 2009 and over the years I have replaced both front headlight assembly, left and right at the cost of $800.00 each. I was told that a bulb blew fusing the wires together resulting in the replacement of the entire assembly. The driver seat head rest simply fell apart.
