Among the 6 Pontiac G6 years with enough history, the three to walk away from are 2005, 2008, 2006; the three worth hunting are 2009, 2010, 2007.

Basic warranty on this car is 3 years / 36,000 miles. Only 12.7% of reported failures happen inside it — the remaining 87.3% 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 7% of the complaints here.

What actually fails — and at what age

What waits further out is Steering at 6.6 years — past every basic warranty, and the bill lands on whoever owns the car then.
