Basic warranty on this car is 5 years / 60,000 miles. Only 30.7% of reported failures happen inside it — the remaining 69.3% come out of the owner's pocket. Powertrain cover (10 years / 100,000 miles) reaches further, but it only covers the engine and transmission, which account for about 18% of the complaints here.

What actually fails — and at what age

On the Mitsubishi Endeavor, the early trouble is Engine And Engine Cooling — reported at around 3.9 years, so a car still under warranty is the one to check for it. What waits further out is Structure at 6.9 years — past every basic warranty, and the bill lands on whoever owns the car then.
