Known issues

Low
BMS calibration drift; range estimate can read low until a full charge cycle resets the gauge.
Medium
Supercharging-frequency degradation reported on early high-mileage Performance trims; Tesla service has issued BMS firmware updates that adjust charging behavior over time.
Low
Cold-weather range loss is consistent with NCM cylindrical chemistry; expect 25-35% reduction at 20°F.

How this pack ages (industry context)

Industry fleet aggregates: 2.3% average annual capacity loss across 22,700 EVs / 21 models (Geotab, 2026), and 95% range retention at 5 years on average across 30,000+ vehicles (Recurrent, 2026).

OEM warranty floor on this pack: 8 yr / 120k mi to 70% capacity.

Public per-pack degradation curves are not available for most models. Individual results vary materially with climate, charging behavior, and DC fast-charge frequency.
