Basic warranty on this car is 5 years / 60,000 miles. Only 97.2% of reported failures happen inside it — the remaining 2.8% come out of the owner's pocket. Powertrain cover (10 years / 100,000 miles) reaches further, but it only covers the engine and transmission, which account for about 28% of the complaints here.
What actually fails — and at what age
On the Kia Niro, the early trouble is Unknown Or Other and Electrical System — reported at around 1.3 years, so a car still under warranty is the one to check for it.
