    Vehicle speed control:accelerator pedal

    On certain passenger vehicles, there is a possibility that the accelerator pedal may temporarily become stuck in the partially depressed position due to inadequate clearance between the accelerator pedal linkage and a plastic pad embedded into the vehicle's carpet.

    Risk: This condition may interfere with the accelerator pedal returning to the idle position, increasing the risk of a crash.

    Remedy: Dealers will inspect the clearance of the acceleration pedal and carpet, replace the pedal assembly with a revised assembly, and modify the carpet free of charge. The recall began on december 27, 2005. Owners may contact lexus at 1-800-255-3987.
