2016 F-250 6.7L Powerstroke, 50,000 miles. All of a sudden a "Coolant change required" warning message is popping up. I just brought it back from a dealer because it has a very slow coolant leak that nobody can trace but that requires topping up every six months. They said the truck is in working order, no issues and cannot trace the leak even after tests when warm or cold the next morning. I just checked and the coolant level is not low. Anyone know what this message is about and what to do about it? Thanks!
