While the Prius’ eCVT Electronically Controlled Continuously Variable Transmission is generally reliable, some owners report:

Delayed acceleration: This can occur when the vehicle is slow to respond, often due to issues with the hybrid system o r eCVT components.
Whining noises: A high-pitched sound, often caused by worn transmission bearings o r inverter issues.
Jerky performance: Can happen when transitioning between electric motor and gasoline engine, often a sign of transmission o r hybrid system troubles.
