ROWS 16·SOURCE NHTSA complaints with incident dates

Basic warranty on this car is 5 years / 60,000 miles. Only 86.8% of reported failures happen inside it — the remaining 13.2% 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 33% of the complaints here.

What actually fails — and at what age

On the Kia Sephia, the early trouble is Service Brakes and Hydraulic — reported at around 1.4 years, so a car still under warranty is the one to check for it.
