If you only Drive 30 miles per week, this will be normal. All Diesel Engines with a DPF Filter need to be run at highway speed for at least 10-15 minutes when hot in order to burn off the ash that ends up in that filter. If you wanted you could ask the dealer to plug in the WiTech and look at the number of regenerations that have happened and I am willing to bet it is more than several hundred. Every once in a while your driving habits don't meet the specifications for what is needed to properly burn off the DPF... Also this is not related to your DEF Fluid, which is to combat NOX in the system, I don't know why they would have gone that route.
Anyway, I can drive 300 Miles in a day or sometimes I drive 3 miles a day for a week. If I keep driving short distances over numerous days and especially if I combine that with lots of remote starts, it will give me a warning that I need to drive as noted (See my picture with 27 Miles, because I didn't go anywhere far when I first got it).
This is not a Jeep thing, it is a Diesel DPF thing and if you have had it happen 6 times, I would say there is no real issues. So when it comes up with that warning, you keep driving until it says the Regen is complete correct? The most important thing, is that it is completing the Regeneration when it asks you to do so, in order to keep the DPF in working order.
Please feel free to ask any questions you like about this process and what is going on but the system is designed to Regenerate itself constantly as well as warn you when it does not meet optimal specs to perform a Regeneration. It is a complex system, and I would be happy to help explain how it works if that helps.
**Edit... I want to make sure I note, that DEF does lots of wonderful things to emissions but it is not the first thing I look at in a DPF issue instance and that I am mainly disappointed that the dealership did not spend some more time explaining the workings of the system as it would likely have taken a lot of stress off of you. **ALSO** I am not physically connected to your truck so I cannot guarantee there is not an issue but from what you have said this seems normal based on my experiences.
