Balance shaft engine issues, stretched timing chain, balance shaft sprockets. There was a class action lawsuit about this that no one made us aware of and the repairs had to be completed by May 13, 2015 to be part of the class action. Now, because we drove it so few miles in the past, the issues have just appeared. We have just 76,000 miles on it and were told that they would have to take the engine apart to replace the camshaft bearings because they have worn due to the other issues. Along with that we needed a new head and gasket and camshaft solenoids. This is estimated to cost us $10,000. We of course aren't going to do the repairs now. There should have been a recall on this so people like us that don't drive a lot of miles don't get ripped off. This is a Mercedes that should have easily run for over 200,000 miles. Now it's junk.
