Basic warranty on this car is 3 years / 36,000 miles. Only 100% of reported failures happen inside it — the remaining 0% 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 few of the complaints here.

What actually fails — and at what age

On the Aston Martin DBX, the early trouble is Structure — reported at around 1 year, so a car still under warranty is the one to check for it.
