Need advice: Coolant is old by time but low mileage

This is usually cheaper to test than to guess. Get a real battery/charging test on the 2024 Tesla Model Y, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. This is from a 2024 Tesla Model Y in Upstate New York. Did the worksheet show tax yet? I keep a notes app thread for this now.

Checked the easy stuff on the 2024 Tesla Model Y and found one clue worth chasing before I book a shop. I'll update if anything new shows up.

If it were in my driveway, get a real battery/charging test on the 2024 Tesla Model Y, not just resting voltage, before blaming a module. That's the branch I'd chase this week. Take it or leave it — that's what I'd do. I'm in no rush to be a hero on it.

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 2024 Tesla Model Y does it — then decide on parts. You'll know quickly if you're on the wrong tree. The universe charges extra for guessing. That's my plan before I call anyone.
