We purchased our 2011 C300 4Matic new in october 2010. My wife had put 40,000 miles on it as of 2/27/2017 when the transfer case started making noise at speed. The local dealer verified the problem and offered a solution of replacing the entire transmission and integrated transfer case for $7855. A week of going back and forth with Mercedes Benz got us a small amount of good will, but this is in our opinion totally unacceptable. We are having the car repaired and will promptly trade it in on different make. What bothers us most is not that the part failed. It just should have been good-willed in its entirety. A quick google search will reveal that the mercedes 722.9 4matic in the c300 is plagued with this problem, and it usually manifests itself right out of warranty. To further salt the wound, we were originally told we would be getting a "new" transmission. When we inquired about keeping the old one, we learned we are actually only receiving a re-manufactured one. $7855 seems outrages for a remanufactured transmission, especially when you consider replacing it is only a 6 hour job. Seems like Mercedes is actually trying to maximize profit in this situation. If I were in the market for any Mercedes Benz, I would definitely google 722.9 transmission problems.
