Basic warranty on this car is 3 years / 36,000 miles. Only 94.1% of reported failures happen inside it — the remaining 5.9% 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 few of the complaints here.

On the Toyota bZ4X, the early trouble is Electrical System and Unknown Or Other — reported at around 1.1 years, so a car still under warranty is the one to check for it.
