Its the turbo coolant supply line, it goes from the driver side head in back to the turbo on passenger side, there is a rubber part in the middle that fails,  Attached a photo of my old hose and new hose.  The Fiat Chrysler mechanic folded a piece of insulation over the rubber to protect it from Turbo exhaust side heat. Mine is a 2016 Grand Cherokee WK Eco Diesel and it failed at 35,000 miles
