No accidents have been reported related to these two problems announced Wednesday, according to Toyota.
Some 1.51 million vehicles are being recalled for the steering defect in Japan and 1.25 million vehicles abroad — including 670,000 in the U.S. Affected models include the Prius hybrid, Corolla, Wish and other models produced from 2000 to 2011 in Japan, and from 2000 to 2009 overseas.
Of those vehicles, some 620,000 spanning five hybrid models, including the Prius, have a defective water pump in addition to the steering shaft defect. Those vehicles were produced from 2001 to 2010 in Japan, and from 2003 to 2011 overseas. Another 10,000 vehicles with only a pump problem are also being recalled.
The latest recalls — affecting Toyota's prized Prius hybrid, a symbol of its technological prowess — come on top of a recall last month for 7.43 million vehicles for a faulty power-window switch that could cause fires.
Toyota has been trying to fix its reputation after a series of massive recalls of 14 million vehicles over the last several years, mostly in the U.S., affecting faulty floor mats, braking and gas pedals.
Before that, Toyota had boasted a reputation for pristine quality, centred around its super-lean production methods that empowered workers to hone in on quality control. Toyota executives have acknowledged the escalating recalls were partly caused by the company's overly ambitious growth goals.
Executives had shrugged off last month's recalls as coming from products made before stricter quality controls kicked in following the soul-searching that came after the recall scandal in the U.S.
But the latest recall underlines how quality problems continue to dog Toyota, especially as it has gone back to pursuing aggressive growth.
Toyota is now headed to record vehicle sales around the world, offsetting a sales plunge in China with booming demand in emerging markets such as Indonesia, India and Thailand.
