Hijjah 24, 1431, Nov 30, 2010, SPA -- Toyota Motor Corp will pay to fix about 650,000 Prius models worldwide for a coolant pump glitch that could cause the top-selling hybrid to overheat and lose power, the automaker said. The repair campaign covers Prius cars for the model years 2004 to 2007. The bulk of the cars, or 378,000 units, are in the United States, Reuters reported. The Japanese automaker said it had not received any reports of accidents or injuries from problems with the pump, which circulates coolant for the hybrid system.
