Basic warranty on this car is 3 years / 36,000 miles. Only 44.1% of reported failures happen inside it — the remaining 55.9% 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

On the GMC Suburban, the early trouble is Service Brakes and Hydraulic — reported at around 2.8 years, so a car still under warranty is the one to check for it. What waits further out is Visibility at 5.3 years — past every basic warranty, and the bill lands on whoever owns the car then.
