2025 Lucid Air — coolant slowly disappears without an obvious leak — North Jersey owner question

TowMechanicish588Community StarterMay 6, 20262025 Lucid Air PureNorth Jersey
The reservoir goes from full to low over several weeks. No puddle, oil looks normal, and I cannot find dried coolant around the hoses. Is a pressure test the next logical move? If I figure it out I will update the thread. Mileage is about 112,000.

Start with the test that can prove you wrong. Get a real battery/charging test on the 2025 Lucid Air, not just resting voltage, before blaming a module. Don't erase codes until someone who can help has seen them. If they can't show the line item, I assume it's hiding. Worth doing even if the car feels fine right now. Only after sitting overnight so far.
