That makes sense. Even vacuuming filling coolant, you can still get some air bubbles.

However, mine never got to the low coolant warning stage as I've caught it early. I had a thermostat fail in first few months and we've had to add coolant once a year since then. I bring it in each time to establish history with the issue because I'm assuming they'll announce a fix for some defect causing this while I'm just out of warranty.
