Engine recalls for the 2006 Lexus IS

  1. NHTSA 09V388000Oct 5, 2009Engine4,445,056 vehicles

    Vehicle speed control:accelerator pedal

    Toyota is recalling certain model year 2004-2010 passenger vehicles. The accelerator pedal can get stuck in the wide open position due to its being trapped by an unsecured or incompatible driver's floor mat.

    Risk: A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death.

    Remedy: Toyota filed an amended defect report on november 25, 2009, stating that dealers will modify the accelerator pedal and, on certain vehicles, alter the shape of the floor surface under the pedal. These changes address the risk of pedal entrapment due to interference with the floor mat. Redesigned accelerator pedals will become available beginning in april 2010 and dealers will replace any modified pedal with the new pedal if desired. Also, dealers will replace any genuine toyota or lexus all-weather floor mats with redesigned all-weather mats, or repurchase the previous mats from owners who do not want the new ones. Additionally, software modifications will be installed on camry, avalon and lexus es 350, is 350 and is 250 models that will ensure that the brake overrides the accelerator in the event both brake and accelerator pedals are applied. Toyota will begin mailing letters to owners on december 31, 2009. Owners may contact toyota at 1-800-331-4331, lexus at 1-800-255-3987.

    Engine and engine cooling

    Toyota is recalling 214,570 my 2006-2008 lexus is, my 2006-2007 gs and my 2007-2008 ls passenger vehicles equipped with aluminum fuel delivery pipes (fuel rails). 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 may illuminate.

    Risk: Over time, the corrosion may create a pinhole resulting in fuel leakage. Fuel leakage, in the presence of an ignition source, could result in a fire.

    Remedy: Dealers will inspect and replace the fuel delivery pipes free of charge. The recall is expected to begin during february 2009. Owners may contact toyota/lexus at 1-800-255-3987.
