When it starts to break
| Age at failure | Complaints | Running total | Warranty |
|---|---|---|---|
| 0 years | 45.5% | covered | |
| 1 year | 71.7% | covered | |
| 2 years | 84.5% | covered | |
| 3 years | 96% | covered | |
| 4 years | 100% | covered |
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 16% of the complaints here.
What actually fails — and at what age
On the Kia Carnival, the early trouble is Electrical System and Unknown Or Other — reported at around 0.9 years, so a car still under warranty is the one to check for it.

| Electrical System | 0.9 yrs | 1 | — | |
| Unknown Or Other | 1 yrs | 1 | — | |
