Basic warranty on this car is 5 years / 60,000 miles. Only 100% of reported failures happen inside it — the remaining 0% 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 20% of the complaints here.

What actually fails — and at what age

On the Hyundai Ioniq 6, the early trouble is Electrical System and Unknown Or Other — reported at around 1.4 years, so a car still under warranty is the one to check for it.
