So I read in this forum that "The final holdup was no urea tanks installed. They literally installed most of them in the storage parking lots."
Maybe this explains why my check engine light came on two hours after I left the dealership. There was a diesel exhaust odor in the cabin and a "Service DEF" message in the EVIC. Was told the DEF tank was leaking and parts were ordered. Been in the shop for over a week and still waiting for it.
Hope this is an isolated problem.
BTW, my trip home was about 15 miles on a 45mph road. Zeroed out the mpg in the EVIC, and had 40.5mpg when I stopped. Continued on another short trip of 30 miles with one stop between and mpg was still over 32. Not bad, short sample size, but a promising start.
