Check Right Tail and Brake Lamps warning light will not go off for months. They are working fine but the light won't go off. Googling on MB World, it shows Mercedes is aware of this problem and a recall is needed to get it corrected being safety issue with warning lights not working properly. See all info. below from owners, conversations and work done by dealers, etc. People note it is a middle school education problem. Please alert me when the recall is confirmed to get this important problem fixed.

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.

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.

I noticed my right tail light has completely went out and related damage to the brown wire connected to the entire casing. Per recall campaign: 2014050001; NHTSA RECALL NUMBER: 14V177, "Oxidation on the ground pin connector for the rear tail lamps of subject vehicles can result in a dimming of the tail lights or loss of tail lamp functions. The loss of a rear tail lamp reduces the rearward visibility of subject vehicles, especially with respect to turn signal illumination and may increase the likelihood of a rear end crash". I recently called a new certified Mercedes Benz dealership near me who states this recall has been closed, however, there is no specific indication on whether that was the right or left tail light. Regardless, a recall covers both whether it happens simultaneously or at different increments. My requested resolution: to simply acknowledge the recall to replace this time the right tail lamp. Especially since any wiring issues poses risk of shortage or fire.

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.

SOCKETS FOR THE PARKING LIGHTS ABOVE THE HEADLIGHTS MELTED. KNOWING THAT SOMETHING SIMILAR WAS ADDRESSED WITH THE TAIL LIGHTS, SEEMS TO BE RELATED. THE TAIL LIGHTS MELTED THE CARRIER AND THE CABLES NOW THE SAME IS HAPPENING ON THE FRONT OF THE CAR. I AM NOT THE ONLY OWNER OF MB C300 EXPERIENCING A ISSUE. WE ARE CONCERNED THAT OUR CARS CAN CATCH UP ON FIRE.
