Answer to: Why you dont like the ISX Engine.Well, where should I start. I bought an ISX15 in a 2005 KW in June 2015. Used to get 6.5 mpg if I drove it like I stole it and 7.5 if driving like grandma. Sept 10, 2015, I broke a crankshaft. Replaced motor with a brand new motor in Oct 2015. Mar 2016, replaced EGR, Apr 2016, replaced EGR Actuator, May 2016, I replaced the head because it cracked across all 6 cylinders. June, rear main seal and I still can not get over 5.5-6 mpg.
