Subject: Special Service Campaign (Safety Recall) 9LA Certain 2006-2007 GS, 2006-2008 IS and 2007-2008 LS vehicles Fuel Delivery Pipe Replacement
Dear Dealer Principal:
Lexus will initiate a Special Service Campaign (SSC) on certain 2006 through 2007 GS 300/350, 2006 through 2008 model year IS 250/350, and 2007 through 2008 LS 460/LS 460L vehicles. The involved vehicles are equipped with aluminum fuel delivery pipes (fuel rails). Lexus has determined that ethanol fuels with low moisture content will corrode the internal surface of the fuel rails. As this condition progresses, the engine malfunction indicator light (MIL) may illuminate. Over time, the corrosion will create a pinhole resulting in fuel leakage.
The following information is provided to advise you and your staff of the owner notification phase of the campaign and your degree of involvement. Additional information may be found in the attached Lexus Q&A and customer notification letter.
OWNER NOTIFICATION DATE
Lexus will begin sending the Special Service Campaign notification in late January 2009 via first class mail.

The involved vehicles are equipped with aluminum Fuel Delivery Pipes (Fuel Rails). Lexus has determined that ethanol fuels with a low moisture content will corrode the internal surface of the fuel rails. As this condition progresses, the engine Malfunction Indicator Light (MIL) may illuminate. Over time, the corrosion will create a pinhole resulting in fuel leakage.

IV. TABLE OF CONTENTS
V. BACKGROUND
The involved vehicles are equipped with aluminum Fuel Delivery Pipes (Fuel Rails). Lexus has determined that ethanol fuels with a low moisture content will corrode the internal surface of the fuel rails. As this condition progresses, the engine Malfunction Indicator Light (MIL) may illuminate. Over time, the corrosion will create a pinhole resulting in fuel leakage.
WORK PROCEDURE
