As part of a reported recall of more than 1.6 million vehicles worldwide, Toyota Motor Sales USA announced plans to conduct a voluntary safety recall of approximately 423,000 Lexus vehicles for an issue with the fuel-delivery system.

Included in the U.S. campaign are:

— Lexus LS from the 2007 through 2010 model years

— Lexus GS from the 2006 through 2011 model years

— Lexus IS from the 2006 through 2011 model years

— Lexus IS C from the 2010 model year

— Lexus IS-F from the 2008 through 2010 model years

In the involved vehicles, OEM officials indicated the fuel delivery pipes in the engine compartment were manufactured with a plating to protect against corrosion. The automaker said some of the pipes could have been produced with plating particles on the gasket seating surface where the fuel pressure sensor is installed.

“In this condition, the sealing property of the gasket seated between the pressure sensor and the pipe could become degraded,” Toyota said. “During vehicle operation, fuel could leak past the gasket.  In the presence of an ignition source, this could increase the risk of a vehicle fire.

Toyota stressed that it is not aware of any fires, crashes, injuries or fatalities caused by this condition.

The manufacturer indicated owners of the vehicles involved will receive a notification by first class mail. Lexus dealers will repair the gasket seating surface of the fuel delivery pipe where the fuel pressure sensor is installed, replace the gasket with a new one and re-install the fuel pressure sensor.

While the amount is high in the U.S., a report from Reuters showed the recall figure is much higher in Japan where more than 1 million units are involved.
