Toyota has announced it will recall 650,000 Prius models to replace the water pump. Technically, this is not actually a recall as the National Highway Traffic Safety Administration (NHTSA) isn’t involved and it is not deemed to be a safety issue.
Toyota will, however, contact owners of affected cars (dating from the 2004 to 2007 model years) starting in December to replace the coolant pump free of charge.
According to Toyota, the design of the pump could cause air bubbles to built up inside, resulting in a loss of cooling and diminished power from the engine.
The majority of recalled cars (378,000 of them) are in the U.S.
