Investigations

NHTSA Investigation US

• EA21002 2021-09-17

  Desiccated Air Bag Inflator Rupture

  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…

By system

• Powertrain (transmission & drivetrain)1 (33.3%)Official recall records for this system: 1, covering model years 2019.
• Speed control & accelerator1 (33.3%)

Other / uncategorized: 1 classifications (33.3%) were not assigned to a specific system by the source. They are counted but not treated as an issue area.

A single report can name several systems, so these figures overlap and must not be added together — their sum is larger than the report total above.

A further 369 complaint records exist for this vehicle where the source stated no model year. They are not counted above and appear on no year page.

These are owner-submitted allegations, not confirmed defects. Counts are record counts in the dataset. No exposure denominator exists, so no failure rate or reliability score can be derived from them.
