76 to 120k was practically trouble free for me. Had an FRM and the active DEF tank go out but they were covered under extended warranty. Replaced the NOx sensors, urea dosing module under the same extended warranty. Had the transmission fluid/filter, diff fluid and transfer case fluid changed also.

Later, had to replace a couple pressure and temperature sensors in the intake system. Also had to replace the HVAC blower motor, throttle valve, glow plugs and module, engine coolant thermostat and elected to replace the transmission fluid thermostat, replacing the fluid at the same time.

143k miles and it's running well but turbos, intake side and intercooler cleaning will probably be next.


Daily driver, a couple thousand miles a month, frequent trips of over 1000 miles, cross-country trips. I can't complain too much.
