WE HAVE BEEN WAITING OVER 3 YEARS FOR THIS MATTER TO BE PUT IN TO AN ACTION PLAN. WE DRIVE THE NOTED 2008 YUKON DENALI DAILY TO AND FROM WORK AS WELL AS TAKE OUR PASSENGERS TO SCHOOL. WE ARE THE ORIGINAL OWNERS OF THE VEHICLE AND WISH TO REQUEST THAT THE AIR BAG NOTED BE SCHEDULED FOR REPLACEMENT. WE ARE NOT COMFORTABLE WITH THE NOTED ISSUES THAT IT MAY CAUSE AND FEEL THAT WE HAVE BEEN P PUT IN HARMS WAY VIA THE KNOWLEDGE AND DECISON TO REPLACE THE DEFECTIVE AIR BAG. PLEASE ADVISE WHEN WE WILL BE ABLE TO RECEIVE THE NEW PRODUCT SUPPLY AND INSTALLATION. TK HOLDINGS INC. ('TAKATA') HAS DECIDED THAT A DEFECT WHICH RELATES TO MOTOR VEHICLE SAFETY EXISTS IN THE PASSENGER-SIDE FRONTAL AIRBAG INFLATORS INSTALLED AS ORIGINAL EQUIPMENT IN CERTAIN 2007 TO 2014 MODEL YEAR CADILLAC ESCALADE, ESCALADE ESV, AND ESCALADE EXT VEHICLES; CERTAIN CHEVROLET AVALANCHE, SILVERADO 1500, SILVERADO 2500/3500, SUBURBAN, AND TAHOE VEHICLES; AND CERTAIN GMC SIERRA 1500, SIERRA 2500/3500, YUKON, AND YUKON XL VEHICLES. THE DETERMINATION WAS MADE THAT THE PROPELLANT IN THESE INFLATORS MAY DEGRADE AFTER LONG-TERM EXPOSURE TO HIGH HUMIDITY AND TEMPERATURE CYCLING, WHICH COULD CAUSE THE INFLATOR TO RUPTURE DURING A DEPLOYMENT. SAFETY RISK AN INflATOR RUPTURE MAY CAUSE METAL FRAGMENTS TO PASS THROUGH THE AIRBAG AND INTO THE VEHICLE INTERIOR AT HIGH SPEED, WHICH MAY RESULT IN INJURY OR DEATH TO VEHICLE OCCUPANTS.

1EA21002 · 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.
