DPF plugging up and poor fuel milage from it(nothing that a big bump can knock off). The integrated trailer brake controllers give quite a bit of trouble, most bypass them and install there own. Only other issue that jumps out at me is there has been quite a few tcm failures on the 6 speeds as they've gotten older. It's not a major problem, but something that has become semi common.
