Desiccated air bag inflator rupture. Open.

NHTSA summary
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 n

Occupant classification system failure. Closed sep 1, 2015.

NHTSA summary
In April 2014, Nissan North America launched Safety Recall 14V-138 to address problems with the Occupant Classification System (OCS) algorithm in the following vehicles: model year (MY) 2013-2014 Nissan Altima, Pathfinder, Sentra and LEAF; MY 2013 Infiniti JX35; MY 2014 Infiniti QX60 and Q50; and MY 2013 Nissan NV 200/Taxi vehicles.According to Nissan, the OCS may misclassify adult front passenger occupants and turn off the passenger's frontal air bag for an adult occupant of sufficient weight.In March 2015, the Office of Defects Investigation (ODI) opened this Recall Query after the agency received approximately 124 complaints alleging problems with the OCS after the recall repairs and/or other OCS related repairs were made by Nissan/Infiniti dealers.The majority of the complaints alleged the passenger air bag status light stays on (i.e., indicating passenger air bag is turned off) for adult front passengers of sufficient weight.Many of the complaints stated the dealers have made multiple repairs but the problem still persists.In its June 2015 response to ODI's information request under the Recall Query, Nissan provided approximately 1,121 complaints and field reports on the recalled vehicles.These reports alleged OCS issues similar to the NHTSA reports described above.At this time, NHTSA has received a total of approximately 208 complaints (note: total of 1,271 reports shown in the table above eliminates 58 duplicative reports received by ODI and manufacturer).This Recall Q

What owners wrote

“I purchased this vehicle last month from Anderson in cockeysville, Md. last week the airbag light came on. I was able to take it to them today 9-15-25 where they at first told me I was over the 1,000miles warranty so I’d have to deal with it on my own. After speaking with a manager, he agreed to take it to Nissan to get a determination.”

“The airbag light in the dashboard always stays lit. It has been worked on at the dealership multiple times and they get it to go out only for it to come back on. It’s concerning not knowing if there is a problem with the airbags itself. This has been on going for years. It started around when my car had 34000-35000 miles on it.”

Should you keep driving it?

This page can't tell you that. 2 of 36 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.

File your own report with NHTSA. Complaint counts are how a problem gets an investigation.
