Did you ever find out what was causing your vehicle to love coolant? We have the same issue in 2015 Renegade. Been going on for a year and we've just kept an eye on it and keep adding to it. Had a couple of people look at it and had it pressure tested - no answer...2017 trailhawk 2430mi....you know I 've had a couple little things going on but latest thing is oil is down 3/4 quart...come be break-in....or under filled when build or combo of both....but the latest thing that's a little more concerning for me is the coolant level is a .75" lower that the low level......never heard of losing coolant during breakin period.
