Toyota Prius: Powertrain
Affects Toyota Prius · 2004–2009 — about 9K vehicles.
The hazard
On certain vehicles, the electrical water pump assembly, used to circulate coolant through the hybrid components, may fail. If this were to occur, coolant would stop circulating, illuminating various warning lights in the instrument panel of the vehicle. In certain cases, the water pump motor could short-circuit, causing the hybrid system to stop functioning and the engine to stall. A loss of propulsion, in conjunction with traffic and road conditions, and the driver's reactions, could increase the risk of a crash causing personal injury and/or property damage. Correction: Dealers will replace the electrical water pump.
