Basic warranty on this car is 4 years / 50,000 miles. Only 31.8% of reported failures happen inside it — the remaining 68.2% 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 few of the complaints here.

What actually fails — and at what age

On the Mercedes-Benz G-Class, the early trouble is Tires and Unknown Or Other — reported at around 3 years, so a car still under warranty is the one to check for it. What waits further out is Structure at 7.5 years — past every basic warranty, and the bill lands on whoever owns the car then.
