There is certainly evidence that they budget on getting engine repairs once the warranty is expired. I think the main issue with ISXs being unreliable now is that they rush the development, focussing mostly on emission numbers to keep their grip on the market just in time for each new wave of emission law.

The ISX is the most researched and developed engine in the Cummins family, and probably the most produced - Yet they are horribly unreliable without extensive maintenance or programming.

If you ever get a chance to see one of the monthly Cummins engineering PowerPoint presentations, it's usually 1/3 ISX bandaid fixes or alerts without a solution, 1/3 Chinese ISF design blunders and the final third dedicated to the rest of their engine range lol.
