Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the coolant every 24,000 mi. The big-interval services (every 24,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2023 Kia Niro EV emerges as the first model year of its generation, registering 15 complaints and 3 recalls—higher than the subsequent 2024 and 2025 model years, which show a clear downward trend in both metrics. Complaints in 2023 are predominantly tied to the electrical system (3) and a mix of powertrain, electrical, and propulsion issues, though the data does not specify root causes. The recall count also peaks in 2023, suggesting early production adjustments common in a new generation’s launch year. By 2024, complaints drop to 6 and recalls to 2, while 2025 data remains limited but shows further reduction. With no fire-related complaints and only 2 crash-related reports in 2023, the vehicle’s safety profile appears stable, though the higher initial complaint volume reflects typical first-year growing pains. **This makes the 2023 Niro EV a reasonable used buy, provided a thorough pre-purchase inspection confirms no unresolved recall or electrical issues.**
