Basic warranty on this car is 4 years / 50,000 miles. Only 100% of reported failures happen inside it — the remaining 0% 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 83% of the complaints here.

What actually fails — and at what age

On the BMW 430i, the early trouble is Electrical System and Power Train — reported at around 0.7 years, so a car still under warranty is the one to check for it.
