I too own a 2014 ecoDiesel
I too own a 2014 ecoDiesel but am in south Texas where I've not experienced problems with DEF freezing. Instead I had diesel exhaust venting into the cab and found there is a connection from the catalytic converter that has design flaws. Chrysler has reengineered the part but they have experienced shortages of the new part. I also had to replace the cruise control as well as the headlight sensor control unit - which took 4 visits to the dealer to sort out. Of course the electrical issues were not diesel related but simply added to my general heartburn. Just yesterday I noticed a strong chemical smell coming through the A/C ducts when the defroster was on on the morning. That is just one more thing for me to deal with. I want to like this truck. But what a pain it has been owning it so far.
