Toyota has announced that it will repair almost 380,000 2004-2007 Prius models in the United States for coolant pump problems. There have been no reports of injuries or accidents related to the problem, but complaints of power loss has lead the company to fix the minor repair without issuing a recall. A Toyota spokesperson explained that air bubbles entering the system through the pump reduces the efficiency of the cooling system. When the pump malfunctions, the car’s hybrid system switches off to prevent overheating and the vehicle’s regular gasoline engine takes over. Overheating of the vehicle could activate a warning light on the dashboard, and a significant loss of power will be noticed. Toyota said it would begin notifying owners of the Prius repair campaign in the United States in early December.
