Spot on.
Since the system is pressurized, there's NFW for "evaporation" unless it's vented to atmosphere. If I were the OP, I'd monitor weekly to see if they can spot anything or measure the loss. Track it, document it, send to corporate and ask them if this is normal. Lots of work but best to address while still under warranty.
My X3 has a coolant smell after a drive but the dealer said they pressurized the system and no leaks were found. I asked how it could smell like coolant if no leak. Shrugged shoulders. I haven't noticed measurable coolant loss so maybe there was a spill at some point of the build? We'll see...
I'll wash the engine compartment out and add a UV dye to the coolant to see if I can find the non-leak...
