Does the market discount it? In our listings a 2010 Prius asks a median $6,200, against $6,400 for a 2011, the next model year: about the same, so the price shows no discount for its complaint record.

Among the 10 Toyota Prius years with enough history, the three to walk away from are 2010, 2008, 2007; the three worth hunting are 2014, 2012, 2013.

Basic warranty on this car is 3 years / 36,000 miles. Only 37.1% of reported failures happen inside it — the remaining 62.9% 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 about 4% of the complaints here.

What actually fails — and at what age

On the Toyota Prius, the early trouble is Hydraulic and Vehicle Speed Control — reported at around 1.8 years, so a car still under warranty is the one to check for it. What waits further out is Service Brakes at 5.7 years — past every basic warranty, and the bill lands on whoever owns the car then.
