Two problems related to water pump have been reported for the 2010 Toyota Prius. The most recently reported issues are listed below.
Tl-the contact owns 2010 Toyota Prius. The contact stated that while driving 70 mph, the vehicle stalled. The check engine and general warning light illuminated. The contact coasted over to the side of the road. The vehicle was towed to a dealer where it was diagnosed that the water pump failed and needed to be replaced. The VIN was not included in the NHTSA campaign numbe: 12v536000 (engine and engine cooling, hybrid propulsion system). The manufacturer was notified of the failure. The approximate failure mileage was 92,000. Aw.
Driving the car at 40 mph went it suddenly stopped. Was able to coast to the side of the road. Found out today that the water pump caused the inverter to become non-working which caused the engine to shut down. Very dangerous. Lucky I was not on the interstate.
