The contact owns a 2009 Mercedes-Benz C300. The contact stated that the coolant warning light was frequently illuminated due to low coolant. The vehicle was taken to an independent mechanic where the engine hose and other engine parts were replaced. Despite the repair, the coolant light returned soon after the initial repair. The contact then took the vehicle to a dealer where the failure was linked to NHTSA Campaign Number: 22V168000 (Exterior Lighting, Electronic Stability Control, Engine and Engine Cooling); however, the VIN was not included in the recall. The manufacturer was not notified of the failure. The vehicle was not repaired. 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.

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.

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 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.

Headlight wires are corroded and melted. This seems similar to the tail light recall a few years ago that caused a fire.

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 for a replacement blub vise $600 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.

I bought my Mercedes Benz and notice that my tail light and the light on the front of the car will turn on by itself while my car was parked in the morning my car battery will be dead needing a charge. I had a recall from Mercedes Benz dealer and I took the car to the dealership and supposedly they fix it and the car had gotten worse. It had burned the harnesses and fog harness, while I was driving the car was acting like shutting off the radio and ac will start shutting off and turning on at the same time while I was on the highway on my way home from work. Right now my car only have working the high beam. I been getting a lot of recalls for this car but really it seems like I'm loosing my time.

"takata recall" I was driving to work around 10:30 am in my 2009 Mercedes Benz C300 enjoying the commute. As I approached the stop light.....blank!!!! I lastly remember breaking....to open my watering eyes to see that I hit another vehicle and don't recall anything at all. As I get up in realized that my head hurts and there was a small tear in the steering wheel as a small portion of the bag deployed but not fully.. it appeared to be a faulty bag that has caused this serious inconvenience.

Takata recall right tail light has a brown burnt wire, and the right rear tail light is dim. So I believe it may have been a recall on this problem. I was wondering if this is something that I need to pay for or would this be something that I could get a recall on? this problem happened while driving on a city street while braking.

Background: In 2014, there was a recall of C-class Mercedes Benz vehicles due to corrosion on the connectors of the rear tail light causing the light to fail. Mercedes Benz fix front light connectors - new issue: Left front parking light is inoperable and the dashboard warning message came on. Went to the dealer to have the parking light bulb replaced. The mechanic verified the concern, replacing the bulb did not work. The mechanic checked and found that the parking lamp harness holder is peeling and corroded causing the wire to short. Mercedes Benz wanted me to pay $1440.35 for the replacement of the entire light assembly and recommended changing the right side too even though it was operable. The light assembly encases the front parking light bulbs (eyebrow lights - 2 each) and the headlight bulb. The service advisor, jeff decorte indicated that he sees this all the time which is why he recommended replacing both sides of the entire light assemblies. Bulb holders and connectors should be replaced at no cost to the owner due to the peeling and corrosion. Please investigate, this may be potentially another recall except now it's the front parking lights. Please note that my car has always been serviced at the required intervals by the dealer.

Car was at the parking front of my home, about to go to work, car won't start, no warning, nothing, completely dead, had to be without car for a week, repair costs 1,200. Towed to Mercedes service. Specific issues was steering column lock failed. I have so many issues with this car, lights, windows, tires, control power fails many times when car is in driving mode. So many owners has same problems, it is a safety issues why this wasn't reported and recall on this one. Thought Mercedes cars are most reliable, obviously that's not true.
