ROWS 13·SOURCE NHTSA complaints with incident dates

Basic warranty on this car is 4 years / 50,000 miles. Only 12.9% of reported failures happen inside it — the remaining 87.1% come out of the owner's pocket. Powertrain cover (4 years / 50,000 miles) reaches further, but it only covers the engine and transmission, which account for about 75% of the complaints here.

What actually fails — and at what age

On the Porsche 911, the early trouble is Seat Belts and 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 Engine at 7 years — past every basic warranty, and the bill lands on whoever owns the car then.
