Thanks for the info! We haven't had a major powertrain issue in any engine since 2011. Hopefully it stays that way!Its not the DEF that's the main issue, its the EGR going out not to mention turbo failures. But back to it, the EGR is what kills longevity of modern diesel engines. They simply don't make them to go 500,000 miles anymore. You're damn lucky to get 200,000 miles before something major happens. I've been told several times by different manufacturers reps that modern gassers combined with 9 and 10 speed transmissions should get you at least 300,000 miles before any major engine work needs to be done. I'm not talking about minor issues or nuisance issues that pop up. I'm talking about the serious powertrain issues - gassers should go 300K as the new standard from what used to be 100K. I had a modern diesel 4 years ago and once it hit 150,000 miles, it was one major issue after the other. EGR failure, turbo failure, then DEF system. I maintained it impeccably too. Nope, not for me.
