Depends on what year. The first ISX engines had a lot of teething troubles. By 2005, they'd gotten them worked out. Late 2008 to 2011 weren't good years for engine manufacturers, as the Diesel Particulate Filters caused a whole lot of problems. 2012 and newer, with the SCR, are much more reliable, as the SCR eliminates the need for an EGR, and greatly reduces the soot load on the DPF.
