Fuel system, gasoline:delivery:hoses, lines/piping, and fittings
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2007-2010 Lexus LS vehicles manufactured May 9, 2006, to July 20, 2010, 2006-2011 Lexus GS vehicles manufactured January 6, 2005, to September 10, 2010, and 2006-2011 Lexus IS vehicles manufactured August 30, 2005, to September 10, 2010. Due to anti-corrosion plating remnants, fuel may leak from where the fuel pressure sensor is attached to the fuel delivery pipe.
Risk: A fuel leak in the presence of an ignition source increases the risk of a fire.
Remedy: Toyota will notify owners, and dealers will clean and reseal the fuel pressure sensor mounting area, free of charge. The recall began March 3, 2015. Owners may contact Toyota customer service at 1-800-331-4331.

Vehicle speed control:accelerator pedal
Toyota is recalling certain model year 2006 and 2007 lexus gs300 and gs350 all wheel drive (AWD) vehicles. There is a possibility that the plastic pad embedded into the floor carpet may interfere with the operation of the accelerator pedal.
Risk: The accelerator pedal could temporarily become stuck in a partially depressed position rather than return to the idle position. A stuck accelerator pedal may result in unintended and sustained vehicle speeds and make it difficult to stop increasing the risk of a crash.
Remedy: Dealers will modify the plastic pad on the floor carpet free of charge. The manufacturer has not yet provided an owner notification schedule. Owners may contact toyota at 1-800-331-4331.
