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 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 us
Door Latch Failures
In December 2019, the Office of Defects Investigation (ODI) opened this investigation based on 235 Vehicle Owner Questionnaires (VOQs) alleging doors failed to latch when closed, and/or inadvertently opened while driving, on model year (MY) 2012-2014 Ford Fiesta, and 2013-2014 Fusion and Lincoln MKZ. Some VOQs reported the failure occurred after the latch had been remedied under a prior recall which involved fracture of the latch pawl spring tab due to thermally induced cyclic fatigue. Other VOQs alleged a similar failure in vehicles not previously recalled. A latch with a fractured pawl spring tab typically results in a ?door will not close? condition, however in certain somewhat rare circumstances, may result in the door coming open while driving. In response to ODI?s investigation, Ford has announced three field actions, as discussed below.On March 23, 2020, Ford submitted Safety Recall 20V-177 (Ford 20S15), a regional recall campaign to address door latch failures in vehicles not previously recalled under Safety Recalls 15V-246, 16V-643 and 17V-210. The recall affects vehicles currently or ever registered in certain high ambient temperature states (see 20V-177 for affected stat
Front Brake Jounce Hose Failures
On August 8, 2022, the Office of Defects Investigation (ODI) opened this investigation based on 50 Vehicle Owner Questionnaires (VOQs) alleging front brake jounce hose ruptures on model year (MY) 2013-2018 Ford Fusion and Lincoln MKZ vehicles. A ruptured front brake hose results in a brake fluid leak. As a result, the driver may experience an increase in pedal travel and a reduction in the rate of deceleration, increasing the risk of a crash. It should be noted that the subject vehicles identified fell outside the scope of NHTSA Safety Recall 20V-469, which addressed front brake hoses rupturing on certain MY 2015-2018 Ford Edge and 2016-2018 Lincoln MKX vehicles. The result causes a brake fluid leak, lengthening the distance needing to stop the vehicle, increasing the risk of a crash.On March 10, 2023, Ford Motor Company (Ford) submitted to NHTSA Safety Recall 23V-162 (Ford Recall 23S12) to address front brake jounce hoses that may rupture. Ford found the rupture occurs from a localized failure of the internal reinforcement braid due to cyclic fatigue through tensile/bending and torsional inputs during suspension and steering articulations. The supplier for the front brake jounce h
About NHTSA Investigations
NHTSA investigations include Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), and Audit Queries (AQ). Investigations may lead to recalls if defects are confirmed. An open investigation means NHTSA is actively examining the issue.
