Basic warranty on this car is 3 years / 36,000 miles. Only 29.5% of reported failures happen inside it — the remaining 70.5% 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 about 15% of the complaints here.
What actually fails — and at what age
What waits further out is Unknown Or Other at 6 years — past every basic warranty, and the bill lands on whoever owns the car then.
