Known issues

High
NHTSA 25V-482 (July 2025) and 26V-068 (February 2026) cover a small number of 2025-2026 Ioniq 5 vehicles whose high-voltage battery system may have an improperly tightened bus bar, which can short-circuit. Owners are told to park outside until dealers inspect and tighten the bus bar bolts and replace the battery assembly as necessary, free of charge.
Low
Hyundai quotes 10 to 80 percent in 20 minutes on a 250 kW or faster 800-volt charger and 24 minutes on a 150 kW charger. Neither standard-range car has a heat pump: Hyundai fits it to all-wheel-drive Ioniq 5s only, and Kia lists none on the EV6 Light.

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: 10 yr / 100k 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.
