Niro Hybrid: What Owners Should Know
- The first-generation Niro Hybrid (2017–2022) uses a 240-volt, 1.56 kWh lithium-ion polymer pack — 64 cells in 4 modules — under the rear seat.
- Its 12-volt lithium battery is integrated with the hybrid battery assembly, so a drained 12V can look like a major hybrid failure.
- Kia’s hybrid battery coverage may still apply on later Niro Hybrids — check with a Kia dealer by VIN before paying for work.
- The Niro Hybrid shares its hybrid system with the Hyundai Ioniq Hybrid.
- Check your VIN for open recalls on NHTSA.gov before paying for any hybrid repair.
