Desiccated Air Bag Inflator RuptureOpen
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…
EA21002 · opened Sep 17, 2021Active Head Rest Inadvertent DeploymentClosed
The Office of Defects Investigation (ODI) opened PE19014 on September 9, 2019, to investigate 128 consumer complaints alleging that the Active Head Rest (AHR) inadvertently deployed without the occurrence of a crash or other rear impact event in model year (MY) 2014 Jeep Grand Cherokee and Dodge Durango vehicles.When ODI opened the investigation, ODI was aware of thirteen alleged injuries.A small number of Early Warning Reports identified driver and/or passenger front seat AHR inadvertent deployments without a rear impact event.Reported safety consequences resulting from the AHR deployments include concussions, headaches, soft tissue injuries, disorientation, nausea, vomiting and/or loss of vehicle control as a result of being surprised and distracted by being struck in the head by the inadvertent AHR deployment. On September 24, 2019, ODI sent an Information Request (IR) letter to Fiat…
PE19014 · opened Sep 9, 2019 · closed Feb 25, 2026Electrical overstressClosedLed to recall 20V024
The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect. During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW.  The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications.  The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal,…
EA19001 · opened Apr 19, 2019 · closed Sep 19, 2024Totally Integrated Power Module FailureClosed
In a letter dated August 21, 2014, the Center for Auto Safety (CAS) petitioned the National Highway Traffic Safety Administration (NHTSA) to initiate a defect investigation of alleged failures associated with the Totally Integrated Power Module (TIPM) installed in Chrysler SUV?s, trucks, and vans beginning in the 2007 model year. The petitioner alleges that TIPM defects may result in engine stall, airbag non-deployment, failure of fuel pump shutoff resulting in unintended acceleration, fire, and other symptoms. On September 25, 2014, the Office of Defects Investigation (ODI) opened DP14-004 to evaluate the petition for a grant or deny decision. ODI analyzed complaint data provided by CAS as well as complaints submitted to ODI from consumers. In total, there were 296 complaints submitted by the petitioner in the original petition and five supplements, including 271 complaints related to…
