Transfer case needs to be replaced.

3 Transfer Case problem of the 2008 Mercedes Benz C300

Failure Date: 09/18/2018

Transfer case reseal. I have a 2008 C300 I bought with 56k miles on it, I had to have the wheel bearings replaced immediately. When this service took place, I was informed that I need to have my transfer case resealed and the cam shaft magnets replaced. This car has such low miles on it. I do not understand how this is needed at this time. I have seen on many boards, this is a common problem. Why hasn't mb recalled this yet? it appears the 2008 model is plagued with problems as I have had to replace the steering lock as well as it failed. Again, common problem and not recall. I now have a seatbelt sensor that faulty. All of this before I have even hit 100k. My 2001 ml is well over 200k and I have never had these issues with the ml.

6 Transfer Case problem of the 2010 Mercedes Benz C300

Failure Date: 08/21/2014

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.

7 Transfer Case problem of the 2009 Mercedes Benz C300

Failure Date: 07/02/2014

Total 4 wheels lock at highway speed without any warning. Recently, a very unsafe incident has occurred to me while I was driving on the highway. I was driving on 202 south heading towards west chester, PA north of exit 29; my speed was about 50 mph. All of a sudden the car went from 50 mph to a completely uncontrolled full stop with 1 to 2 seconds. The tires left skid marks on the road. The seat belts avoid me from being thrown out of the car. I tried to move the car in order to avoid traffic coming at me at 50 mph but I could not. The wheels of the car suddenly locked up and the car could not be moved. Luckily, the car behind me was able to stop without anyone getting heart. Also all the incoming car at the highway speed were able to suddenly avoid hitting me. This incident occurred without any warning or any indication that there is a problem with the car. This could have been a multi car accident with possible major injuries or possible fatalities. The police could not believe that this can happen and they have never anything like this before. The car was towed to the mercedes dealer. The dealer called me back telling me that it was the sudden failure of the front differential without any warning. I called mercedes and they responded by saying that there was a leak in the transfer case. I indicated that the car is parked in a garage and I would have seen the leak from the transfer case. I would like this incident be seriously reviewed by mercedes in order to avoid this from occurring on the road again and by the department of transportation or other government authorities. Again, luckily no one was hurt.
