This is my 1st diesel, but my 4th dodge truck. I'd probably go back to a 5.7 gasoline 1500. Goodness knows I could trade in for the top trim level with the cash back from the diesel.
It's hit or miss because of it being a new manufacturing process - a new-to-Dodge diesel engine being fit into a new transaxle and all the pitfalls that unfortunately get worked out on the customer end. My gut tells me that majority of the check engine light issues that are exhaust related are probably due to this leakage at the turbo junction - the sensors are expecting a different level of pollutant and even a small leak before the sensor(s) can cause the system to burn/convert/catalyze improperly.
My biggest letdown has been the fuel mileage - when I drove it home I got 28 mpg driving 80mph! It's been downhill from there with highway miles around 22 and some city miles as low as 15... And it was the city mileage that was appealing to me - I could get a truck that would tow, and a commute that wasn't going to kill me like my 1500 and 2500 I've had in the past. Factor in 50% higher cost in diesel fuel over gasoline and it's just not performing smartly over the 5.7 for me - realizing that others are doing OK. I do have higher miles on my vehicle than a few of the posters at this point with 11,000, so perhaps other will have similar issues in time.
