Basic warranty on this car is 4 years / 50,000 miles. Only 20% of reported failures happen inside it — the remaining 80% 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 20% of the complaints here.
What actually fails — and at what age
On the Infiniti FX37, the early trouble is Power Train — reported at around 3 years, so a car still under warranty is the one to check for it. What waits further out is Fuel/propulsion System at 5.5 years — past every basic warranty, and the bill lands on whoever owns the car then.
