2024 Tesla Model Y Long Range — battery keeps dying after two or three days parked

Battery tested okay at a parts store, but if the car sits for a weekend it sometimes won't crank. Alternator voltage looks normal while running. How would you narrow down a parasitic draw without pulling every fuse blindly? Any data points from owners would help.

If it were in my driveway, write temp, speed, and in-gear vs coast when the 2024 Tesla Model Y does it — then decide on parts. Don't erase codes until someone who can help has seen them. I'd want a dollar figure or a measured spec, not 'should be fine.' Not trying to scare you — just skip the expensive first guess. Might be overthinking it, but I'd rather overthink than overspend.
