    Nissan North America, Inc. (Nissan) is recalling certain model year 2006-2010 Infiniti M35 and M45 vehicles manufactured April 4, 2004, through October 5, 2010. Over time, the accelerator pedal sensor signal may deteriorate resulting in the output of an incorrect signal causing the engine to go into fail-safe (limp home) mode.

    Risk: In this fail-safe mode, throttle valve deposits may cause the engine to stall when the vehicle is coming to a stop or at idle, increasing the risk of a crash.

    Remedy: Nissan will notify owners, and dealers will replace the accelerator pedal assembly and reprogram the engine control module, free of charge. The recall is expected to begin during November 2013. Owners may contact Nissan at 1-800-647-7261.
