I did a search and saw a lot of mentions about this engine, but not a lot about reliability. I realize this is a relatively new combination, but does anyone know anything specific about this powertrain? I realize there are lots of diesel forums out there, but I'd rather get the straight shit from you guys. Just how good is this engine? When Chrysler and Fiat announced the merger, I remember saying to myself, "the blind leading the blind..." I realize MB and Chrysler were the ones to design the Grand Cherokee, so I'm sure that the chassis is good, but this diesel engine has piqued my interest. Is this diesel engine on par with anything from MB or Audi? Is it more of a commercial grade diesel? What about Fiat diesels in general? What about long term reliability? Has anyone here ever driven it in either the JGC or the Ram? There used to be a guy here that worked for Cummins. Cool guy. Is he still around?
