Okay here's my problem. I bought a 2015 xlt 4x4 6.7 with 22k miles on it for 41k. Very clean truck and is certified so I keep the 100k warranty. I have almost 29k on it now and I really wan to delete it to avoid the def system faults. The whole idea of the truck going in limp mode from a sensor is bs in my opinion. So many people need these trucks to rely on to make them money day in day out. So my question is should I delete and throw out the warranty or ride it till 100k and delete it then. I don't have a huge budget for major repairs if something did happen if it wasn't covered but I stay on my mantinance really good. But I also don't want a failure due to emmisions. What would you guys suggest?
