2024 Polestar 2 — how are owners measuring real battery degradation? — buyer question from Long Island

Intermittent stuff lies if you only catch it once. Two 2024 Polestar 2s can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. On “how are owners measuring real battery degradation?,” that was the fork that mattered for me. This is from a 2024 Polestar 2 in Long Island with 21,500 miles. If they can't show the line item, I assume it's hiding. I'll poke at it this weekend.
