Toyota Motor plans to recall about 533,000 Sequoia SUVs and Tundra pickup trucks in the United States to repair faulty components that could make the vehicles difficult to steer.
Six injuries and 11 accidents were reported as a result of the defect, Japan's top auto maker said today.
Toyota, on its way to becoming the world's biggest auto maker ahead of General Motors, has vowed to step up its quality efforts after a rise in vehicle recalls and increased scrutiny from Japanese media over quality issues.
The latest recall covers certain 2004 to 2007 model year Sequoias and 2004 to 2006 model year Tundras, both built at Toyota's Indiana plant, the auto maker's US sales unit said.
Toyota last year recalled more than a million vehicles in Japan and 760,000 units in the United States, but the publicity has done little to hurt it.
Toyota boosted its global sales by 9 per cent in 2006, fuelled largely by a 13 per cent jump in sales in the United States.
Recalls have also been on the rise across the industry as car makers use common components on various models to save costs. The Tundra and Sequoia, both of which are due for a full remodelling, share most of the same components.
