The engine itself is reliable, but cars with this version are already between 11 and 17 years old: check that the Prius III campaigns were carried out (brake actuator, hybrid system software) and inspect the condition of wear items (12 V battery, water pump, hybrid battery).[2][3]
Faults that affect 2017 cars
- Critical severityFrequency: OccasionalElectronicsBrake actuator failure (hard pedal, loss of assistance)Yes, it is a documented fault on the Prius III: the diaphragm of the brake actuator's accumulator can degrade and make the pedal very hard, forcing you to brake with much more force. Toyota ran a campaign in 2013; there are also owner reports of actuators failing after the warranty had expired.
- High severityFrequency: RareElectronicsDegradation or premature failure of the hybrid batteryIt is a component that generally lasts very well (there are units above 300,000 km), but there are isolated cases of premature failure, mainly on the Auris Hybrid, between 77,000 and 80,000 km, with repairs of around €2,800-3,000. We have not found a manufacturer campaign for this.Repair: €2,800–€3,000
