Basic warranty on this car is 3 years / 36,000 miles. Only 23.6% of reported failures happen inside it — the remaining 76.4% 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 9% of the complaints here.
What actually fails — and at what age
On the Mazda CX-3, the early trouble is Electrical System and Steering — reported at around 3.8 years, so a car still under warranty is the one to check for it. What waits further out is Unknown Or Other at 4.1 years — past every basic warranty, and the bill lands on whoever owns the car then.
