I HAVE NOTICED MY DASH IS MELTING TERRIBLY BAD ITS NOW HAS SOFT SPOTS AND IS NOW SUPER STICKY FROM MELTING AND CRACKING AND CHIPING OFF IN SOME AREAS WHERE IT HAS MELTED AND THEN CRACKED AS IT HARDENED BACK. IF I TRY TO CLEAN IT WITH CLEANER MADE FOR DASHES THE COLOR JUST SMEARS AND THE DASH MATERIAL ITS SELF SMEARS AND ANY KIND OF CAR CLOTH JUST LEAVES PATCHES OF STUFF FROM THE DASH BEING STICKY AND MELTED. THIS HAS BEEN A COMMON PROBLEM I AM FINDING ALL OVER THE WEB. WHY ARE OUR DASHES NOT BEING FIXED? THIS CAN CAUSE MAJOR ISSUES IF I WAS TO GET INTO A WRECK AND THE DASH JUST CRUMBLES OR SQUISHES BECAUSE ITS MELTED.

DURING NORMAL OPERATION, THE SEAT HAS FAILED IN IT'S ORIGINAL DESIGN INTENT. I BELIEVE THAT THE A FAILURE IN SOME COMPONENT UNDER THE SEAT CAUSED STRESS ON THE PIVOT POINT FOR UP-DOWN MOVEMENT IN THE SEAT AND OVER AN EXTENDED PERIOD OF TIME THE POINT FINALLY SHEARED. I BELIEVE THE EXTENSIVE STRESS WAS CAUSED BECAUSE OF THE AUTOMATIC SEAT MOVEMENT THAT OCCURS WHEN THE DRIVER ENTERS AND EXITS THE VEHICLE THE BRACKET WHICH ALLOWS THE SEAT TO MOVE UP AND DOWN WITH THE POWERED CONTROL HAS FAILED ON BOTH SIDES OF THE LEFT FRONT BUCKET SEAT. THE SEAT NOW MOVES FREELY FORWARD AND BACK AND POSES A SERIOUS SAFETY RISK TO MYSELF AND ANYONE ELSE WHO MIGHT BE DRIVING THE VEHICLE. THIS PUTS ME IN A TERRIBLE POSITION BECAUSE AS A CONCERNED CONSUMER I HAVE TO WORRY ABOUT THE FACT THAT AN ACCIDENT COULD BE FATAL DUE TO COMPONENT FAILURES. SHOULD I MOVE FORWARD WITH GETTING RID OF THE VEHICLE, EITHER BY SELLING IT TO ANOTHER PERSON OR TRADING IN THE VEHICLE, I PUT SOMEONE ELSE IN RISK AND/OR WILL TAKE A HUGE LOSS ON THE VALUE OF THE VEHICLE BECAUSE OF THE CONDITION WHICH WAS CAUSED BY POOR DESIGN AND/OR QUALITY TESTING. THIS IS A SERIOUS ISSUE AND NEEDS TO BE REMEDIED BY NISSAN USA IMMEDIATELY!

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.
