What you are saying about the setup of the emissions components makes sense. However, isn't this vehicle supposed to heat up the whole DEF system? I've read several articles online that even in extreme cold temps for prolonged periods of time the system will work fine! I still don't understand why we're seeing a bunch of Canyonrado Diesels and I don't think they're all driving around in limp mode. Anyway, we just got a rental car. We are paying for a rental but we'll see what GM reimburses or not. More worried about completing as much of our trip as we can and then getting home on time. We got set back almost 2 days because of this! The plan is to come back through here to pick up our truck after it's been repaired. I am a little concerned that that won't happen in time, though. They already said the soonest they can even begin to look at it is tomorrow (Thu) so let's say it's simple and they figure it out and they order the part and it comes on Friday and they put it in, it'll be done on Fri. But we all know that that's not how it works. Do any of you, especially those of you that work in a dealer service department, think our truck will be done anytime soon?

It's similar to the VW TDI and Cruze diesel component arrangement. The 2.8 has a "truck" like DPF and SCR arrangement, where they are long and laid out in the truck frame. The 2.8 is also very efficient so not much heat is generated with the stock tuning. A 2.8 w/ a VW tune or Delete tune would be best for an adventure vehicle.
