2022 Limited Coolant Loss

My 2022 Limited non hybrid is losing coolant. The levels in both the engine and intercooler reservoirs has dropped below L in the last six months. I have an appointment at my dealer scheduled for when the fuel line fix is in but in the meantime I’m wondering how I’m getting this coolant loss. No drips on the floor, don’t see anything when I changed the oil. It’s both reservoirs so I’m thinking a small leak at the water pump maybe? Pinhole leak at the radiator or cap? Any thoughts? I’m headed there to grab some coolant for a top off in the interim.

 

Don't know if this helps but the first year of ownership of my 124 showed a reduction of coolant in the overflow tank that finally settled. My assumption was the system was taking time to get all the air out of the system.

Use a Sharpie to mark the level and note ambient temps and monitor under the same conditions to see if this continues.

My 21 Tundra level hasn't moved since new.
