What's wrong

Nissan North America, Inc. (Nissan) is recalling certain model year 2013-2014 Infiniti M35 hybrid vehicles manufactured April 7, 2012, to September 9, 2013, 2014 Infiniti Q50 hybrid vehicles manufactured December 10, 2012, to July 15, 2014, and 2014-2015 Infiniti Q70 hybrid vehicles manufactured April 9, 2010, to May 7, 2014. Due to a software error, In the affected vehicles, if the signal is lost from one of the two throttle position sensors (TPS), the engine control module (ECM) will go into a fail-safe mode, partially closing the throttle chamber. Should the lost signal be restored, the throttle chamber may open, regardless of the position signal from the TPS.

Consequence

The vehicle may gradually accelerate due to the throttle chamber reopening. This unexpected acceleration may increase the risk of a crash.

Remedy

Nissan will notify owners, and dealers will reprogram the ECM, free of charge. The recall began on November 10, 2014. Owners may contact Nissan customer service at 1-800-647-7261.
