(October 15, 2014) Toyota today announced it is recalling 1.67 million vehicles globally in a voluntary move to address three separate defects including a faulty brake master cylinder that could hinder the brake's performance.

Some 1.05 million vehicles will be recalled in Japan and 615,000 overseas, covering Toyota models Crown Majesta, Crown, Noah, Voxy, Corolla Rumion and Auris, as well as Lexus models including the IS, GS and LS sedans.

Toyota is recalling about 802,000 Crown Majesta, Crown, Noah and Voxy models manufactured between June 2007 and June 2012 to replace a rubber seal ring in the brake master cylinder to prevent brake fluid from leaking. If brake fluid has already leaked, the brake booster will be replaced.

A second recall of about 759,000 vehicles globally, including 423,000 in the United States, will fix faulty fuel delivery pipes that could, in the worst-case scenario, cause a fire through a fuel leak. Some of these vehicles are also subject to the first recall.

Toyota will also recall in Japan 190,000 front-wheel drive Corolla Rumion and Auris models built between October 2006 and October 2014 that are not equipped with an idling feature to fix a defective fuel evaporative emission control unit.

The safety campaign is Toyota's fourth this year involving at least 1 million vehicles as the auto industry responds to scrutiny over tardy recalls.

Carmakers have faced heightened global scrutiny on how quickly they share information with regulators and the public since a massive recall crisis in 2009 battered Toyota's reputation and sales. Most vehicle recalls are issued on a voluntary rather than mandatory basis.

Toyota recalled 6.39 million vehicles globally in April in its second-largest recall announcement ever. Two months later, the company issued a recall of almost 2.3 million vehicles globally for faulty airbag inflators that have also plagued other car makers.

Toyota said it was not aware of any crashes, injuries or deaths resulting from the defects.
