Basic warranty on this car is 4 years / 50,000 miles. Only 80% of reported failures happen inside it — the remaining 20% 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 80% of the complaints here.
What actually fails — and at what age
On the Porsche 718 Cayman, the early trouble is Engine and Seat Belts — reported at around 0.3 years, so a car still under warranty is the one to check for it.

|---|---|---|---|---|
