As of today the remedy is not available. There is a fault switch with the headlights in off position the left right turn signal flash when the keys are not in the vehicle. It drains the battery which have replaced twice. We determined that if we keep the light switch in automatic position it does not happen.

2 years ago manager told me the wiring of the head lamps was melting but he can only replace the whole unit( both). I told him that a car with 30000 mils this should not be happening. Nothing he can do. The car has started to burn on the inside , smoke comes out of the engine. Car transports children. To and from school. Eery other onth lamps burn out, happening since the car was new. Finally went to shop again today and they put it on paper. Wire coating falling apart, causes burn out of lamps. This is a huge danger and should be recalled not paid by user. Have sent 2 other complaints to the federal safety agency with no resolution. Why????? Additionally car has had tail lamp problems since the beginning with one recall. Additionally the seat cover of the driver side is coming apart in pieces since year 2. How is it possible no action has been taken?

Second warning regarding the electrical wiring regarding the front head lamps. The wiring is burning up and it will cause a fire with deadly consequences. This car has had a recall before regarding the wiring of the back stop lights, if nothing is done there will be a fire. The seat (front) covering is peeling off, co. Says its normal. This is my 2nd report and the smoke is getting heavier all the time and it is affecting the computer of the car function. The vehicle is always picking up children with my wife. Very difficult to get photo, but is visible on both sides of the front head lights. There has been no fire yet but there is smoke.

The wiring to the head lambs (both) are burning up, causing a burnt smell in the car, company says to buy new head lamps. The electric wire system in the car has been a problem since the beginning. Evidently the heat in the motor area is to much for the quality of the wiring covers and they cause lamp burn out,and burn the plastic wire covering. Car is used for pleasure has very few miles. Very hard to take a picture , tech had a hard time getting to it.

Got home from work parked my car, I would say maybe about 3 hrs later I get on my car to go pick up my son and I wasn't able to turn my car on. My keyfob worked fine when I unlocked and locked the vehicle but when I would insert the keyfob in the ignition I was able to turn the key all the way to the on position. All though it turned in the ignition it wouldn't give the car a crank or any power at all, the radio, windows dashboard, headlights, nothing worked at all, it wouldn't even unlcock my steering coloumn either. Which made it even a bigger hastle to tow the car without being able to turn the steering wheel luckily ii left the wheels straight when I parked my vehicle. I've seen that this issue is common on this mercedes model. If its a common problem mercedes should be able to recall this ignition fault. Theres plenty of reasons why it can be a stressing situation if it happens to anybody, especially not being able to unlock thje steering column. There can be plenty of what if's (what if, u had ur wheels turned, what if your far from home, ur parked in a tight space how are you going to get the car towed, you have an emergency and your car suddenly wont start, at a gas station pumping gas and your car wont start, even after just having dinner at a restaurant) imagine having an issue like this and you are with ypur family its very stressful or everybody. I'm sure its happened to a lot of people but they dont file a complaint or maybe they dont know they can file one. I just hope mercedes can really do something about this issue since is very common on this model 2009 mercedes c350.

I had just stopped to put gas in the vehicle and upon completion I got back in the car to start it. When I turned the key, the car wouldn't start. I had headlights and my dashboard was partially lit up, but nothing else would work. I then called the mb road side assistance and a technician came out and determined it was not a battery or starter problem. The technician said that it was probably the eis since he had seen the same situation before. An hour later the car was towed to the dealership, and dropped off with much trouble since the steering column didn't function. Several days later I got a call from my service consultant, informing me that the car needed the ignition starter switch as well as the eis unit and two new keys needed to be programmed. The total was $2500. In the meantime, I found a tsb number 2008020003, dated march 1, 2008, documenting the exact problem I was having. It appears that it was a know problem even back in 2008. My car is in excellent condition and it has only 32,260 miles. Why didn't this become a recall? I also feel like I was robbed on the cost of the repairs. I'll never trust this car again and I'm not buying another mercedes.

I have a 2008 mercedes benz c350. The rear passenger taillight malfunctioned causing me to be pulled over by the police. Mercedes benz has since recalled the faulty tail lights and is scheduled to release replacement parts to mb dealers next month. However, it seems the entire electrical system is defective. Sometimes the radio station changes when I adjust the cabin air temperature (air conditioner). The dashboard control panel constantly displays warning messages about failing headlights and side markers. Aside from the recalled passenger taillight which is visibly dimmer than the driver side taillight, the other lights appeared to be working fine. Yesterday the fuel gauge indicator and the coolant indicator on the dash came on - the antifreeze and fuel tanks are both full. I had a mechanic look at the lights, only to discover the plastic housing is completely singed and melted in the headlights and side markers, just like it is in the defective recalled taillight. The car is one over-priced fire trap - at this point I don't feel safe driving it. What is even more disturbing to me, is that mercedes benz is well aware of electrical problems with the c class. There are thousands of complaints about this issue online - posted to blogs and the federal safety agency website. Mercedes is trying to piece-meal out a remedy. Meanwhile, this is a big safety issue! When will the federal safety agency recall the entire mercedes c class line due to defective electrical issues?
