Headlight bulbs failed. Owners manual states that the low beam bulb on the driver's side can be replaced by simply removing back cover, inserting hand and removing and replacing bulb. However, this is fraudulent. Every mechanic and the mercedes dealers state that the bumper and possibly fender must be removed to replace this safety item. The bulb went out on a trip and could not be replaced even though the bulb was readily available and I purchased it at a walmart but could not replace it. Even though the walmart replaced bulbs, after I waited 2 hours they told me they could not do it. I took it to two mechanics and they said they "did not have time" since it required disassembly of the vehicle. The mercedes dealership said they could not provide an estimate because it required substantial time and disassembly. Now I have a car that has a bulb out, it cannot be driven at night, and to replace the bulb it requires an appointment at mercedes and apparently hundreds of dollars of expense for labor. Like windshield wipers, tires, etc, etc, this is obviously a critical safety item and mercedes has committed fraud in its representation that the bulb can be owner replaced. My car now is a danger driving at night. The NHTSA has statutory responsibility for the safety of vehicles and the internet has endless entries about the difficulty of replacing the headlight bulbs on this vehicle. I pay taxes. Do something.
