ROWS 16·SOURCE NHTSA complaints with incident dates

Basic warranty on this car is 3 years / 36,000 miles. Only 14.5% of reported failures happen inside it — the remaining 85.5% 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 54% of the complaints here.

What actually fails — and at what age

On the Mazda RX-8, the early trouble is Engine And Engine Cooling — reported at around 3.8 years, so a car still under warranty is the one to check for it. What waits further out is Power Train at 6 years — past every basic warranty, and the bill lands on whoever owns the car then.
