2018 JLUS 2.0 with 98,000mi, relatively trouble free until lately.

I’m losing coolant somewhere along the intercooler system. The reservoir bottle (clear front of engine drivers side) was empty after 1,000mi driving. I traced coolant lines as best I could and could not see any residue anywhere and can’t find any information or posts about common failure points.

Seem to have some impact to gas mileage, power but it’s been above 90F and using AC may be contributing.

Any ideas? I ordered some compatible UV coolant dye and a UV light to see where there’s a source.
