Basic warranty on this car is 3 years / 36,000 miles. Only 23.6% of reported failures happen inside it — the remaining 76.4% 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 11% of the complaints here.
What actually fails — and at what age
On the Pontiac G8, the early trouble is Suspension and Power Train — reported at around 2.4 years, so a car still under warranty is the one to check for it. What waits further out is Air Bags at 6.3 years — past every basic warranty, and the bill lands on whoever owns the car then.
