Basic warranty on this car is 4 years / 50,000 miles. Only 37.5% of reported failures happen inside it — the remaining 62.5% 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 17% of the complaints here.

What actually fails — and at what age

On the Volvo S40, the early trouble is Service Brakes and Hydraulic — reported at around 3.6 years, so a car still under warranty is the one to check for it. What waits further out is Electrical System at 6.1 years — past every basic warranty, and the bill lands on whoever owns the car then.
