Air Bags › Frontal › Passenger Side › Inflator Module · Jan 9, 2020

NHTSA campaign 20V008000 · 307,962 vehicles

Problem
Nissan North America, Inc. (Nissan) is recalling certain 2001-2003 Maxima, 2002-2006 Sentra, 2002-2004 Pathfinder, 2007-2011 Versa Sedan and Versa Hatchback, 2001-2004 Infiniti I30 and I35, 2002-2003 Inifiniti QX4, 2003-2008 Infiniti FX35 and FX45 and 2006-2010 M35 and M45 vehicles. The vehicles are equipped with non-desiccated, frontal passenger air bag inflators containing phase stabilized ammonium nitrate (PSAN) propellant that were used as interim remedy parts for previous Takata recalls. These inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, high temperatures, and high temperature cycling.
Risk
An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Fix
Nissan will notify owners, and dealers will replace the front passenger air bag inflators with alternate desiccated inflators, free of charge. The recall began February 12, 2020. Owners may contact Nissan customer service at 888-737-9511 or Infiniti customer service at 888-810-3715.

Additionally, if not included in "Zone A" or "Zone B" above, Nissan is recalling certain 2005-2008 Infiniti FX35 and FX45, 2006-2010 Infiniti M35 and M45, and 2007-2008 Nissan Versa vehicles originally sold, or ever registered, in Alaska, Colorado, Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
Risk
An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.
Fix
Nissan will notify owners, and dealers will replace the front passenger air bag inflators, free of charge. The recall began on June 8, 2017. Owners will receive a second notice when remedy parts become available. Owners may contact Nissan customer service at 1-800-647-7261.

Vehicle Speed Control › Accelerator Pedal · Sep 26, 2013

NHTSA campaign 13V430000 · 98,307 vehicles

Problem
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.
Fix
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.
