Basic warranty on this car is 3 years / 36,000 miles. Only 19.2% of reported failures happen inside it — the remaining 80.8% 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 28% of the complaints here.
What actually fails — and at what age
On the Mazda RX-7, the early trouble is Service Brakes and Hydraulic — reported at around 2 years, so a car still under warranty is the one to check for it. What waits further out is Engine And Engine Cooling at 4.6 years — past every basic warranty, and the bill lands on whoever owns the car then.
