ROWS 3·SOURCE NHTSA complaints with incident dates

Basic warranty on this car is 4 years / 50,000 miles. Only 75% of reported failures happen inside it — the remaining 25% 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 Audi RS 4, the early trouble is Suspension and Electrical System — reported at around 2 years, so a car still under warranty is the one to check for it. What waits further out is Air Bags at 9 years — past every basic warranty, and the bill lands on whoever owns the car then.
