A LITTLE SCARY DON'T YOU THINK? THE VEHICLE ALSO HAD THE CHECK ENGINE LIGHT ON. I LATER HAD THE CAR DIAGNOSED AND IT PULLED AN PO340 CODE(CAM POSITION SENSOR, CRANK POSITION SENSOR) WHICH WAS SUPPOSEDLY RECALLED BY NISSAN ON OCT 04. MY CAR'S MANUFACTURE DATE WAS 12/02. I CALLED NISSAN CORPORATE AND THEY TOLD ME THAT APPARENTLY MY CAR WASN'T UNDER RECALL WHEN A BUNCH OF OTHER WEBSITES(CARS.COM, INTERNETAUTOGUIDE.COM, NHTSA.GOV). I KNOW THIS DOESN'T MAKE ANY SENSE WHEN MY LIFE WAS IN DANGER AND I OWN 2 OTHER NISSAN CARS, I DON'T GET WHY A COMPANY WOULDN'T CARE ABOUT ITS LOYAL CUSTOMERS. I AM A COLLEGE STUDENT AND LOOKS LIKE THIS ISSUE IS GOING TO RUN ME $1200.00 WHEN PERSONALLY I DON'T KNOW WHY I NEED TO BE PAYING FOR IT WHILE THE SAME CAR HAS A RECALL ON IT AND THE RECALL HAPPENS TO BE THE SAME PROBLEM MY CAR HAS.

20V008000 · Air Bags:frontal:passenger Side:inflator Module

Jan 9, 2020

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.

Consequence & remedy

Consequence: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

Remedy: 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.

May 15, 2015

Nissan North America, Inc. (Nissan) is recalling certain model year 2001-2003 Nissan Maxima, 2002-2004 Pathfinder, 2002-2006 Sentra, 2002-2003 Infiniti QX4 and I35, 2003 FX35 and FX45, and 2001 I30 vehicles. Upon deployment of the passenger side frontal air bag, excessive internal pressure may cause the inflator to rupture.

Consequence & remedy

Consequence: In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.

Remedy: Nissan will notify owners, and dealers will replace the passenger air bag inflator, free of charge. The recall began on June 15, 2015. Owners may contact Nissan customer service at 1-800-647-7261. Note: On December 18, 2015 Nissan informed NHTSA of an amendment of this recall to remove 2004-2005 Infiniti FX35 and FX45 vehicles.

ON CERTAIN PASSENGER VEHICLES, THE CIRCUIT BOARD FOR THE CRANK POSITION SENSOR OR CAM POSITION SENSOR MAY HAVE AN IMPROPER SOLDER JOINT DUE TO SOLDER DEFORMATION CAUSED BY HEAT STRESS ACCELERATED BY THE EXISTENCE OF FLUX RESIDUE DURING THE SOLDERING PROCESS.

Consequence & remedy

Consequence: THIS COULD CAUSE THE "SERVICE ENGINE SOON" WARNING LIGHT TO COME ON, CREATE A NO START CONDITION, CAUSE REDUCED ENGINE POWER, OR CAUSE THE ENGINE TO STOP RUNNING WITHOUT WARNING DURING VEHICLE OPERATION, WHICH COULD RESULT IN A CRASH.

Remedy: DEALERS WILL REPLACE THE CRANK POSITION SENSORS. CAMSHAFT POSITION SENSOR(S), AND IN SOME CASES, THE VARIABLE TIMING CONTROL SENSOR(S). VEHICLES INVOLVED IN A PREVIOUS RECALL CAMPAIGN, 01V357, ARE ALSO INCLUDED IN THIS NEW CAMPAIGN. THE REPLACEMENT SENSORS USED IN THAT CAMPAIGN ARE ALSO AFFECTED. OWNER NOTIFICATION BEGAN ON DECEMBER 22, 2003. OWNERS SHOULD CONTACT NISSAN AT 1-800-647-7261 OR INFINITI AT 1-800-662-6200.

EA21002 · Desiccated Air Bag Inflator Rupture

Opened Sep 17, 2021 · No close date supplied

Status: open (inferred from source dates) · Air Bags:frontal:driver Side:inflator Module; Air Bags:frontal:passenger Side:inflator Module

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.
