Known issues

Low
Ioniq 5 N is performance-tuned; sustained track use (10+ minutes at peak power) triggers thermal derating to protect cells. This is the trade-off between performance and pack longevity, not a defect.
High
Same ICCU recall family as the 77.4 — Performance trim is not exempt.
Low
Range is similar to 77.4 because the 84 kWh pack is heavier; the additional capacity offsets the higher curb weight more than it extends range.
Low
2025 refresh of standard Ioniq 5 may shift to the 84 kWh pack as the new long-range tier; check spec sheet at point of sale.
