Reason for recall: In the Hybrid system of the subject vehicles there is an electrically driven water pump assembly that circulates coolant through the hybrid components. It is possible the coil wire of the electric motor installed in the water pump may have been scratched during the coiling manufacturing process at the supplier. In this condition the coil wire may corrode at the scratched portion and in some cases break. If this occurs the water pump could stop working leading to illumination of various warning lights in the instrument panel. In some cases a short circuit occurs between adjacent coil wires resulting in a blown fuse for the electric power supply circuit. This will cause the hybrid system to stop while the vehicle is being driven which increases the risk of an accident.
