Basic warranty on this car is 3 years / 36,000 miles. Only 37.5% of reported failures happen inside it — the remaining 62.5% 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 34% of the complaints here.
What actually fails — and at what age
On the Pontiac Montana, the early trouble is Engine And Engine Cooling and Structure — reported at around 3.9 years, so a car still under warranty is the one to check for it. What waits further out is Electrical System at 4.1 years — past every basic warranty, and the bill lands on whoever owns the car then.
| System | Complaints | Typical age | Crash | Fire |
|---|---|---|---|---|
| Engine And Engine Cooling | 3.9 yrs | — | 1 | |
| Electrical System | 4.1 yrs | 2 | 9 | |
