Basic warranty on this car is 4 years / 50,000 miles. Only 33.9% of reported failures happen inside it — the remaining 66.1% come out of the owner's pocket. Powertrain cover (6 years / 70,000 miles) reaches further, but it only covers the engine and transmission, which account for about 17% of the complaints here.

What actually fails — and at what age

On the Acura RDX, the early trouble is Engine and Power Train — reported at around 2.8 years, so a car still under warranty is the one to check for it. What waits further out is Exterior Lighting at 7.5 years — past every basic warranty, and the bill lands on whoever owns the car then.
