Vehicles Affected: More than 6,500 model-year 2013-14 Infiniti M35h hybrid luxury sedans manufactured between April 7, 2012, and Sept. 9, 2013; model-year 2014 Q50 Hybrid luxury sedans manufactured between Dec. 10, 2012, and July 15, 2014; and model-year 2014-15 Q70 Hybrid sedans manufactured between April 9, 2010, and May 7, 2014
The Problem: Due to a software error, if the signal is lost from one of the two throttle position sensors, the engine control module will go into a fail-safe mode, partially closing the throttle chamber. If the lost signal is restored, the throttle chamber may open regardless of the position signal from the throttle position sensors; this could cause the vehicle to gradually accelerate unexpectedly, increasing the risk of a crash.
The Fix: Infiniti manufacturer Nissan will begin notifying owners in mid-November, and dealers will reprogram the engine control module for free.
What Owners Should Do: Owners can call Nissan at 800-647-7261, the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236 or go to www.safercar.gov for more info.
