I have a 2011 3500 dually which has had no mechanical issues but has been a constant PIA with codes for NOx sensors, glow plugs, reluctant quality, def tank heater, etc many of them multiple times. I have not been able to enjoy my truck because of the constant fear of CEL coming on during a long trip. My extended 10 year emissions warranty will be up next year. My question is do the new trucks have problems with emissions largely corrected or is it still a gamble? My truck was the first year for def so I assume we were used as guinea pigs and hopefully many of the early issues have been corrected. I love the power and economy but can’t stand the uncertainty of being able to drive long distances without the fear of CEL interrupting the trip. Should I trade for a new 19 or 20 Duramax or forget it and go with gas? Also worried about the fuel pump grenading as many have reported.
