I got a 16 2500 with cummins. at 18,000 I had to have a wheel hub assembly placed. Got 40,000 on it now and just had a sensor replaced. It would sporadically pop up on my info screen "4WD shift in progress". My biggest gripe is when I go get service work done they tell you u got some updates that are available, but then they want to charge you for doing those updates!!
