The 2005 Toyota Prius has 2 recalls, the most serious involving the steering shaft's internal splines, which can wear down over time and eventually cause a complete loss of steering control.
The hybrid system also has a concern: a scratch inside the electric water pump's coil wire can corrode over time, causing the wire to break and the pump to stop. This water pump cools the inverter, so if it fails, the inverter can overheat and shut down, potentially leaving the vehicle without drive power.
