Toyota has announced a voluntary recall of some 740,000 vehicles in the United States to address a potential leak problem with a seal in the brake master cylinder. The models that are being recalled in the U.S. are the 2005-2006MY Toyota Avalon, 2004-2006MY Highlander (non Hybrid) and Lexus RX330, and 2006 Lexus GS300, IS250, and IS350. Another 600,898 vehicles were recalled in Japan and approximately 200,000 in China for the same issue.
According to the company, there's a possibility that a small amount of the brake fluid could slowly leak from the brake master cylinder, resulting in illumination of the brake warning lamp.
"If the brake warning lamp has illuminated and the vehicle continues to be operated without refilling the master cylinder brake fluid reservoir, the driver will begin to notice a spongy or soft brake pedal feel and braking performance may gradually decline," said the automaker.
Toyota said it will begin notifying owners of the involved vehicles through mail beginning in early November 2010. As with all recalls, Toyota and Lexus dealers will replace the brake master cylinder cup with a newly designed free of charge.
