Took delivery of mine on 11/23/13, one of the first JGC diesels in OK, I believe. Converter replaced a few months later. Works fine, now; very pleased, now.
I have had to become rather insistent that the dealership service department completely "fill" the DEF tank. I also insist, before I take it in, that they have sufficient diesel oil & DEF on hand. I am not customarily so demanding, nor do I usually need to be. Now, I am acquainted with both the service rep. and service manager. Some of the initial issue seems to have been that this dealership, perhaps many others, were not in the beginning well prepared to service JGC diesels. Things seem to be more on course, now, after my initial frustration with Jeep and the dealership service. By the way, often the DEF display takes a while to reset. So, the service tech may be estimating how much DEF is required rather than filling until it overflows. DEF, I'm told, is a rather messy liquid.
OMG! Are you serious? Run away from that stealership as quickly as you can; they're either incredibly stupid and ill informed, or think you are.
Why are you demanding it be filled? General consensus at this point is that you want to keep fresh DEF in tank and only add a recently manufactured 2.5 gal. container at a time. DEF Blue from Walmart or an automotive store appears to work best and there is information on other forums that allows you to read the manufacture date code on the containers. The newer the DEF, the less likely to crystalize and throw one of the infamous codes.
I appreciate your advice. I have followed closely the various posts concerning DEF. I decided some time ago to have the dealership service department perform all maintanance. My thinking is, if there is a problem, then the responsibility lies with them & Jeep. I am aware of the reports in this forum of a crystalization issue. However, I have not received any notification from either the manufacturer nor the dealership concerning this. And, I have not had any problem since the converter was replaced even though I do get the DEF tank filled completely. Of course, you may be correct, and it will catch up with me; in which case I will let Jeep sort it out for me. I quit some time ago worrying about what might happen. I bought the extended warranty just in case. We'll see. Again, I appreciate your suggestion. I guess I just approach the issue differently. However, full disclosure, I did not feel this way 10,000 miles ago.
