Toyota to Repair Water Pumps on 650,000 Prius Gas-Electric Cars Worldwide

Toyota Motor Corp., the world’s biggest seller of hybrid-electric automobiles, said it will repair about 650,000 Prius cars worldwide to correct a water- pump flaw that can cause the vehicles to lose power.

Toyota plans to fix 378,000 vehicles from model years 2004 through 2007 in the U.S., John Hanson, a spokesman for the Toyota City, Japan-based company, said yesterday. The automaker, the world’s largest, will also repair 180,000 Prius cars in Japan, 70,000 in Europe and 7,000 in Australia for the same flaw, Tokyo-based spokesman Paul Nolasco said by phone today.

A fault in the water pump can cause air bubbles to build up and disrupt the flow of coolant, which can lead to overheating, Hanson said. In the U.S., the repair campaign isn’t a recall as Toyota determined it’s not a safety issue and here have been no accidents or injuries connected to the flaw, Hanson said.

Toyota rose 0.9 percent to 3,330 yen in Tokyo as of the 11 a.m. trading break today. The shares have fallen 14 percent today.
