Powertrain cover (4 years / 50,000 miles) reaches further, but it only covers the engine and transmission, which account for about 36% of the complaints here.
What actually fails — and at what age
On the BMW 540i, the early trouble is Hydraulic — reported at around 3.8 years, so a car still under warranty is the one to check for it. What waits further out is Engine And Engine Cooling at 4.9 years — past every basic warranty, and the bill lands on whoever owns the car then.
