Five problems related to headlights have been reported for the 2009 Mercedes Benz C300. The most recently reported issues are listed below.
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.
This 2009 C300 was purchased new from the Mercedes Benz dealership in jacksonville FL as a retirement gift for 20 years of naval service. About a year later I noticed the daytime running lights continuously blinking during the day. The next problem is with the front headlight units each time a blubs blows, it fuses everything including wires together requiring the replacement of the entire headlight unit. This has happen three times with both the left and right headlight units. The difference in price is $28. 00 for a replacement blub vise $600. 00 plus dollars for the entire unit. The dealership has no problem charging me the cost to replace a manufactures defect and safety issue. There should be an immediate recall of this unit.
