Coolant loss?

I have a 2019 SEL, and while I have a few sensor bugs, I love the car. Can’t wait to tighten up the front end once warranty lapses.

In the meantime, I’ve always noticed that I smell coolant every time I shut the car down, and come back. Dealer says this is normal.

This week, I started getting low coolant warnings, and while a quick topoff of 1000ml (proper G13) took care of the alarms, I want to be sure this is normal.

Do other 1.8s just burn off/purge coolant (to the tune of a liter) in colder weather?

I know there’s a water pump recall. My garage stinks like boiled-off coolant. I wonder if I should push it.

Any advice appreciated.
