I checked my records, no flushes under my ownership. However, carfax shows that when the car was about 1yr/5k miles old, it got a new water pump and hence coolant flush at the dealer. So the coolant in it is from 2014. In the first year I had it, I kept an eye on it, kept making sure it was above minimum and when I complained, I got a new coolant cap (still under warranty).

Since then, so we're talking since 2016-2017 or so, I have not been checking, just waiting for the idiot light to go on. It seemed to much trouble to keep it just above the 'min' mark. Min to max seems really close, I wonder how much capacity there is between the 'yellow' warning and the minimum. From the looks of it at least a quart, we'll see.
