Basic warranty on this car is 4 years / 50,000 miles. Only 40.7% of reported failures happen inside it — the remaining 59.3% 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 31% of the complaints here.
What actually fails — and at what age
On the Infiniti G20, the early trouble is Engine And Engine Cooling and Service Brakes — reported at around 3.5 years, so a car still under warranty is the one to check for it. What waits further out is Power Train at 6.7 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Engine And Engine Cooling | 3.5 yrs | 1 | 1 | |
