The diaphragm material in the fuel pulsation dampers in certain 3.5-liter V6 gasoline engines may harden over time and crack, causing fuel to leak.
A fuel leak in the presence of an ignition source can increase the risk of a vehicle fire.
What to do
Lexus notify all known owners and dealers will replace the fuel delivery pipe with a new one containing improved pulsation dampers at no cost.
Owners may contact Lexus at (800) 255-3987.
