Transfer case needs to be replaced

I got Mercedes Benz C300 2010 in less than 6 months, the vehicle developed power steering lock issue; the vehicle will not start and got me stranded in a parking lot of a grocery store. I researched the problem online and realized several individuals have had similar issue. I brought the issue to mbusa, they did not deny its a common issue but said based on the history of the vehicle I am not eligible for any relieve on the cost of repair. I feel it is unfair that I will have to pay for something I believe its a manufacturer default. Now I am compelled to pay $1,700 for the repairs.

Gear shifter will get stuck in park when parked on a slight incline, such as a driveway or small hill. I absolutely have to park on a flat surface if I want to get my shifter out of park. I have to tap on the top of the shifter and continue to try to get it out of park. This can take anywhere from 10-30 minutes and has happened multiple times. Very frustrating and I've only had the car a couple of months. Now I have to put money in to fix it already. Why is there not a recall on these vehicles with this problem? from my research, it seems as though plenty of Mercedes has this problem.

While driving the vehicle, began hearing a humming underneath the car thinking it might have been the tires. The sound got louder as the days went on. Took vehicle to be serviced and was told that the problem was the transfer case and that the solution was a new transmission approximately $8000-$10000. Was also advised that other owners are having this same problem yet mb refuses to acknowledge currently.

Transmission has gone completely out at 30,000 miles and Mercedes refuses to respond.

Speed dependent front end noise and vibration. Inspection by mb authorized dealer indicates: "front transfer case coming apart". mb customer service indicates that the problem is a "one off" but offered a 50% discount on repair. Repair cost is $7000. Suspect that this is not a "one off" and the problem is more frequent given the immediate offer of a discount on repair. Failure of the front transfer case at any speed can and most likely will cause wheel lock up, engine failure, loss of power assisted controls (steering and braking), loss of electrical systems (air bags), and possibly created an accident with fatalities.

On 12/22/12 at approximately 9pm I was parking my car having arrived at my destination. I had almost finished parking when my Mercedes Benz C300, 2010 lunched forward without warning and hit the truck in front of me resulting in a chain rection. With that truck smashing into the vehicle infront of it. I honestly believe that the vehicle suddenly accelerated on its own and therefore must have malfunctioned. I went searching and found similar complaints from a couple of other owners of Benz C300 2010 model.I called Mercedes Benz usa and reported and was told that I need to take the car in and pay for it to be diagnosed. They insisted that they have not heard of any similar complaint. I am concerned that this may happen again.
