I read all the internet and forums almost every C300 has the same problem. It's not fair to the consumers that we pay for a manufacturing malfunction. Car won't start and show a msg of take car of ignition. It's a $2000 fix for something small but only can be fixed at the dealership. It's a highway robbery in bright day light. Please save the consumers from a greedy company. Last time I will ever own a Benz.

Rear tail lamp electric harness melted. Specifically the brown wire. This also melted the terminal leading to a fire hazard and the lights not working. This is after the lights were "fixed" for the recall.

My right tail light keeps dimming and going back bright. I thought I needed a bulb but but it gave me a message today for everything on the right side but then the message went away. Last night someone told me the right light was dim then it got brighter. I've been smelling a faint burning smell but today it was kind of loud. I checked and it looks like the plastic and wire is melting on rte right tail light.

When I turn the key to turn on the car, when it is parked, absolutely nothing happens. I have heard that this has happened to other people with Mercedes ignitions

The steering lock failed. Stopped at the post office and my car would not start when I got back to the car. The door locks would work but the ignition would not read my fob. I did a little research and found that this is a common problem.

Electronic steering lock problem. While attempting to start my vehicle from a parked state. The vehicle will not allow me to start the vehicle and my steering wheel is stuck. Dealer wants to charge me $1800 for a problem that many other Mercedes Benz owners are having. If you google my Mercedes Benz C300 wont turn over. This problem is common. I have power to radio, instrument cluster and lights. Unable to unlock my steering wheel and start the vehicle.

My vehicle was running superior, no warning signals or straining when powering on. Parked car then an hour later tried turning vehicle on and will not turn on for any reason just radio worked. Found out it was steering module needed to be replaced for a hefty $1100. Had the car for only 3 months and barely used it. I believe it's a recall on these issues.

The vehicle would not start at all. Battery was replaced and still did not start. Mercedes Benz dealer stated that it needs an electronic steering lock. Apparently this is a common problem with Mercedes Benz sedans. The vehicle was parked.

I drove my car to a restaurant. After about 15 minutes, I returned and tried to crank the vehicle. The key fob did not unlock the stirring wheel and tires. I had it towed to the dealership and was told it was a steering column issue. Enough of an issue that it cost me $1000 to repair. I started researching and found that there are many complaints about this same issue. There are references to both the esi and/or esl failures. This is a known issue with Mercedes Benz and I am concerned that this is a safety issue as motorist are left stranded unless towed.

The contact owns a 2010 Mercedes-Benz C300. While attempting to drive the vehicle, it failed to start. The vehicle was not taken to a dealer or independent mechanic to determine the cause of the failure. The vehicle was not repaired. In addition, the contact received notification of NHTSA campaign number: 16V081000 (air bags); however, the part needed for the repair was not available. The contact stated that the manufacturer exceeded a reasonable amount of time for the recall repair. The vehicle was not taken to a dealer. The manufacturer was not notified. The approximate failure mileage was 72,000.

Drove my car to work everything was fine.. when I went to leave I turned the key and nothing happened.. after talking with a mb service consultant he is informed me that it is probably the electric ignition switch.. doing some research online I see that this is a very common problem.

Takata recall. The contact owns a 2010 Mercedes-Benz C300. The contact received notification of NHTSA campaign numbers: 16V081000 (air bags) and 16V363000 (air bags). The contact stated that the part was not available within a reasonable time frame to schedule the recall repair. The dealer (dick dyer Mercedes-Benz and Volvo, 5825 two notch rd, columbia, SC 29223, (803) 786-8888) did not give a specific date for when the part would become available. The contact was unable to determine when the vehicle would be repaired. In addition, the key would not turn over intermittently and prevented the vehicle from starting. The dealer replaced the ignition switch, which did not prevent the failure. The vehicle was taken back to the dealer where it was diagnosed that the starter needed to be replaced. The contact was uncertain if the dealer and the manufacturer would be able to provide a solution or if the oem part would fail again, if replaced. The manufacturer was notified of the failure and the concerns with the two air bag recalls. The approximate failure mileage was 130,000. VIN tool confirms parts not available.

Drivers side lock does not function. When coming up to speed door does not lock posing a safety issue of the door opening in an accident. It is also very inconvient to manually look the door as it only will lock after being closed.

My 2010 Mercedes C300 has a faulty electronic steering lock fail-which left me stranded sitting in the park lot about 30 minutes from home. Car would not start I tried to start my car and nothing happens. When I turn the key to on nothing lights up, no crank, no clicks, no windows and no radio. I would lock and unlock with the remote but that was about it. I tried jumping and I tried both keys still nothing happens when I turned the key. Steering wheel was locked and gear stuck in park. Had to have it towed to the mb dealership to have the steering lock and key replaced and ending costing $1,124. I have read that this has happened to a whole of mb's and should be a recall. I mean really we pay to have a quality car and so far my mb has had a stinky ac that mb could never figure out how fix, taillight recall, found oil leaking from oil centerfuge cover that cost $199.62 but yet it still leaks oil., currently waiting for the takata airbag inflator recall from April 2016 and today is Dec. 2016. Very disappointed in Mercedes and will not be purchase again nor will I recommend to anyone. Even the service at the dealership has gone down. Quality and customer service is not what it use to be.

Over the ownership of this vehicle I have had to replace several electrical components. These include more than I have time or space to list them, but the latest is now the comand buttons on the dash board which no longer function. I was told ican have this fixed for the low price of $2,000 to replace the entire system.
