Toyota is recalling about 423,000 older-model Lexus luxury cars in the U.S. and almost 19,000 in Canada because a gasket can leak fuel and possibly cause a fire.

The move is among three global recalls that Toyota announced Wednesday totalling about 1.7 million vehicles.

The Lexus recall covers the LS model from the 2007 through 2010 model years, as well as the 2006 to 2011 GS and IS. Also affected are the 2010 IS-C and the 2008 to 2010 IS-F. All have Toyotas UR or GR engines.

The company says in a statement that a fuel system gasket can become degraded and leak. No fires, crashes or injuries have been reported.

The Lexus recall is part of a larger recall of 759,000 cars that also covers the Crown Majesta, Crown and Mark X in Japan. Those cars were built from January of 2005 through September of 2010.

Toyota says Lexus owners will be notified by mail starting in December as the company makes parts and develops a special tool for dealers to replac the gasket.

Also Wednesday, Toyota announced two other recalls:

 about 800,000 cars in Japan, China and elsewher in Asia to fix potential brake master cylinder leaks. The recall covers the Crown Majesta, Crown, Noah and Voxy models built from June of 2007 through June of 2012.about 190,000 Corolla, Rumion and Auris models built from October of 2006 through October of this year. Dealers will fix a faulty fuel evaporator emissions control unit.
