2018 Subaru Forester — coolant slowly disappears without an obvious leak

If it were in my driveway, loaded-suspension checks on the 2018 Subaru Forester catch play that a wheels-hanging inspection misses. That's the branch I'd chase this week. This is from a 2018 Subaru Forester in Long Island with 63,000 miles. Take it or leave it — that's what I'd do. Not trying to scare you — just skip the expensive first guess. Cold start is when I can actually reproduce it.

Ask what changed right before it started. Two 2018 Subaru Foresters can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. Write the result down so the next test isn't a repeat of the last one. Doing the boring step first on purpose.
