Is My Coolant low?

[JayceeP]

Was checking the oil on my 2024 Yukon XL and had a look at the coolant reservoir in the first 2 pics (Engine Coolant Surge Tank). Is this too low? It’s a long weekend here so I’ll reach out to the dealer in the am. Hitting the highway later this week so trying to get answers asap.

It was this level a couple weeks ago but I forgot to follow up on it.

The 3rd pic, Charge Air Coolant Surge Tank, does look good however. Not sure how one ties into the other. Assume the Charge tank being full is more important?

I had seen this on mine maybe a couple of years ago. I filled it up above the cold mark with the appropriate coolant and it's pretty much been good ever since. There could have been a one-time reason why it got low. I wouldn't read a whole lot into it unless it's taking it down to the bottom on the regular.
