2024 Rivian R1S Dual-Motor — anyone else: Battery keeps dying after two or three days parked

2024 Rivian R1S Dual-Motor, about 37,000 miles. 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?

OP here. Still looking, but I'm waiting on inspection notes before I send money on the 2024 Rivian R1S. Doc fee is the line I'm watching.

I'd want competing paper, not competing stories. A written buyer’s order on the 2024 Rivian R1S is worth more than any verbal “we’ll make it work.” I'd rather lose the car than buy a foggy deal. Learned this the expensive way on a previous car. Sleeping on the number either way.

Don't send a deposit on a phone quote. If they're pushing term length to shrink the payment, the 2024 Rivian R1S price probably got worse. Screenshot the worksheet if you can. Happy to compare notes if your setup is different. A day of patience here is cheaper than a wrong part. If the title is messy I'm out, full stop.

Insurance and tax belong in the comparison, not as a surprise. A written buyer’s order on the 2024 Rivian R1S is worth more than any verbal “we’ll make it work.” I'd rather lose the car than buy a foggy deal. On “motor — anyone else: battery keeps dying,” that was the fork that mattered for me. Learned this the expensive way on a previous car. I screenshotted the quote for later.

I hear you, though I'd still want a second check. GAP, paint, and nitrogen are optional until you run the 2024 Rivian R1S numbers without them. Do that before you talk monthly again. Had a similar mess a couple years ago and that's what finally sorted it. This is the version I'd tell a friend.
