Basic warranty on this car is 4 years / 50,000 miles. Only 9.8% of reported failures happen inside it — the remaining 90.2% 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 35% of the complaints here.

What waits further out is Suspension at 7.1 years — past every basic warranty, and the bill lands on whoever owns the car then.
