Need advice: Battery keeps dying after two or three days parked

I'd want a measurement, not a hunch. Two 2023 Hyundai Ioniq 5s can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. This is from a 2023 Hyundai Ioniq 5 in Las Vegas with 22,000 miles. Keep sale price, fees, and rate as three different conversations. I'd rather be boring and correct. This is the version I'd tell a friend.
