Basic warranty on this car is 4 years / 50,000 miles. Only 25% of reported failures happen inside it — the remaining 75% 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 25% of the complaints here.

What actually fails — and at what age

What waits further out is Electrical System at 7.6 years — past every basic warranty, and the bill lands on whoever owns the car then.
