When it starts to break
| Age at failure | Complaints | Running total | Warranty |
|---|---|---|---|
| 0 years | 100% | covered |
Basic warranty on this car is 3 years / 36,000 miles. Only 100% of reported failures happen inside it — the remaining 0% 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 about 100% of the complaints here.
What actually fails — and at what age
Systems by number of complaints, with the age at which each typically goes. The age column is the useful one — it tells you what to expect next on a car you already own, and what to inspect on one you are about to buy.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Engine | — | — | 2 | |
| Electrical System | — | — | 1 | |
| Fuel/propulsion System | — | — | 1 |
