The 5.9 common-rail is divided into two separate groupings: the earlier 2003-04 models and the later 2004.5 to 2007. As part of our “What Breaks When” series, this week we’re taking a closer look at the 2003 to 2007 5.9-liter Cummins. While the 5.9 Cummins is a very robust engine, it does have a few weaknesses that can leave the truck stranded, but nothing that will lead to a catastrophic failure or meltdown. 2016 - 2022 Canyon/Colorado 2.8L DuramaxĢ003 marked the first year of a new body style pickup for Dodge, and to go along with its new looks, a new engine could also be found under the hood, and the major difference between it and the earlier 5.9 liter Cummins engine (and its Achilles heel) was the addition of common-rail fuel injection.
