This is my second EcoDiesel.  Had a 16, never had a single problem with it, and at 102K miles I traded for a 20 Ram with a Hemi.  I missed the 16 diesel engine and forked up for a 22 Eco.  My first trip to Texas I averaged 32.5 MPG and I am a happy camper.  One of my sons has a new Nissan and after driving my 22 Ram, he's changing brands..
