2024 Tesla Model Y — how are owners measuring real battery degradation?

Log the conditions before you spend. If a shop can't duplicate it on the 2024 Tesla Model Y, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. On “how are owners measuring real battery degradation,” that was the fork that mattered for me. Stop there until you know. If your situation is the opposite, ignore me. I'm keeping receipts and dates in one folder.

I wouldn't throw parts yet. Move a coil or plug on the 2024 Tesla Model Y if it's cylinder-specific and see whether the code follows. You'll know quickly if you're on the wrong tree. This is from a 2024 Tesla Model Y in Brooklyn. No need to make it theatrical. Might be overthinking it, but I'd rather overthink than overspend.

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 2024 Tesla Model Y does it — then decide on parts. Save the big job until that test fails. No need to make it theatrical. If the story changes I'll post the new data.
