Basic warranty on this car is 4 years / 50,000 miles. Only 30.6% of reported failures happen inside it — the remaining 69.4% come out of the owner's pocket. Powertrain cover (6 years / 70,000 miles) reaches further, but it only covers the engine and transmission, which account for about 17% of the complaints here.
What actually fails — and at what age
On the Infiniti I30, the early trouble is Service Brakes and Hydraulic — reported at around 2.7 years, so a car still under warranty is the one to check for it. What waits further out is Air Bags at 7.9 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Air Bags | 7.9 yrs | 10 | 1 | |
| Electrical System | 7.1 yrs | — | 6 | |
| Suspension | 6 yrs | 3 | — | |
| Service Brakes | 2.7 yrs | 4 | — | |
| Hydraulic | 2.7 yrs | 3 | — | |
| Structure | 9.6 yrs | 1 | 1 | |
| Engine And Engine Cooling | 7.1 yrs | — | 3 | |
