NOx error
Pulled this code..correlates with having a intermittent but obvious jerking (like a misfire would feel) only while in drive either at a light or driving low speeds. I'm worried because I add my own DEF fluid and don't want to be declined warranty service. I'm at 24308 miles
Does DEF go bad in truck?

So are you saying that DEF that is in the tank can go bad? I have a 2013 3500 and put less than 9K per year mileage. I get about 5,000 per DEF fill up. I fill up about every 7 months on DEF. I only buy it at the pump at major truck stops. Do I need to be worried that it may go bad before I fill up again?
Also why the concern about filling you own DEF? Do they think we are going to go back to the dealer every time we need a DEF fill up?
