|---|---|---|---|
| 4 years | 16.7% | you pay | |

Basic warranty on this car is 3 years / 36,000 miles. Only 0% of reported failures happen inside it — the remaining 100% come out of the owner's pocket. Powertrain cover (5 years / 60,000 miles) reaches further, but it only covers the engine and transmission, which account for few of the complaints here.
What actually fails — and at what age
What waits further out is Exterior Lighting at 6 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Exterior Lighting | 6 yrs | — | — | |
| Visibility/wiper | 11 yrs | — | — | |
| Equipment | 9 yrs | — | — |
