L5P Add coolant notification

Hi
I have a L5P with 10K miles and have the add coolant message twice, takes about a quart each time no visible leaks any ideas?

I would take it to the dealer. I had a 2013 Chevy Cruze that would lose coolant. I took it to the dealer every time because
1) it's free
2) they document that it is losing coolant

Eventually, they figured out it was a bad waterpump seal on that whole line of engines and replaced it. If people don't bring problems to the dealer, they can't figure that kind of thing out.

Thanks for the advice

Update on coolant loss went to the dealer they said the issue comes from an air space in the system, they install a special left hand threaded fill cap and and coolant under pressure. Evidently they were not all filled properly at the factory, otherwise it will burp itself over a period of time.

Mine started doing the same at 10k mi, burped a few times since.
