Basic warranty on this car is 4 years / 50,000 miles. Only 35.5% of reported failures happen inside it — the remaining 64.5% 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 about 16% of the complaints here.

What actually fails — and at what age

On the Cadillac Deville, the early trouble is Hydraulic — 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 7.8 years — past every basic warranty, and the bill lands on whoever owns the car then.
