MKCProblems & recalls

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.

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 states). As a remedy, Ford will replace all four door latches free of charge.On August 24, 2020, Ford issued a non-safety regional field action (Ford 20R01) to address door latch failures on the same model/MY vehicles not covered under 20V-177 (i.e., not currently/ever registered in affected states). According to Ford, spring tab failure rates for vehicles covered by this action are about half that of the 20V-177 vehicles. Under this action, dealers will replace all door latches, free of charge, if either; a) the vehicle exhibits a related latch concern, or b) if the vehicle owner expresses a concern about the latches in their vehicles. Details can be found under NHTSA TSB No. 10190990, a copy of which is available in this investigative file available at NHTSA.gov.On June 8, 2020, Ford submitted Safety Recall 20V-331 (Ford 20S30) addressing vehicles previously remedied under NHTSA Recalls 15V-246, 16V-643 and 17V-210, where the repair may not have been properly completed, specifically not all of the door latches were replaced, or replaced correctly. This recall involves an inspection of the latches, with the option for a consumer self-inspection; owners could view the date codes on their latches (and confirm child safety locks are present on the rear doors) and then submit the information to Ford?s mobile app or website. A dealership inspection option was also available. Any vehicle found to have unreplaced defective latches requires the replacement of all door latches as directed by Ford.Regarding the 4,494 reports cited above, 1,485 involve scope-related failures (with 13% alleging door opening), and the remaining 3,009 reports involving remedy concerns (with 18% alleging door opening - note ODI was unable to verify the allegations of door opening). The three ODI injuries were all relatively minor. Ford?s reported injury incidences include one (unconfirmed) report of an ejection, three minor injuries with the others involving undisclosed injuries. Ford?s crashes involved two (unconfirmed) crashes alleging the incident door contacted another vehicle and three involving doors striking other property.The recalled vehicles include MY 2011-2015 Ford Fiesta, 2013-2016 Ford Fusion and Lincoln MKZ, 2015 Ford Mustang and Lincoln MKC, 2013-2015 Ford Escape and Ford C-MAX, 2012-2015 Ford Focus and 2014-2016 Ford Transit Connect.Ford's actions address ODI's concerns at this time. ODI will take further action if warranted by new information. The reference (OD

In January, the Office of Defects Investigation (ODI) opened this Preliminary Evaluation based on consumers' allegations of doors failing to latch and/or inadvertently opening on model year (MY) 2012-2013 Ford Focus vehicles (subject vehicles).ODI has received 464 unique reports related to the alleged problem, with over 200 claiming that the door(s) opened inadvertently while the vehicle was in motion.One consumer alleged an injury that occurred while driving when a door inadvertently opened and then closed on a child's arm.Another alleged that a door that inadvertently opened struck a parked vehicle.In response to ODI's information request, Ford Motor Company (Ford) provided 500 unique reports related to the alleged problem on the subject vehicles.Ford reported no injury or accident claims.Ford also submitted 1,513 warranty claims related to door latch failures.Many customers indicated that the affected door could not be latched at all and some of them decided to restrain the door by other means in order to operate the vehicle.Some customers also reported door latch failures occurring on multiple doors and at different times.Additionally, Ford stated that MY 2014-2015 Ford Focus, 2013-2015 Ford Escape, 2013-2015 Ford C-Max, 2014-2016 Ford Transit Connect, 2015 Ford Mustang, and 2015 Lincoln MKC, all use the same door latch as the 2012-2013 Ford Focus.On September 6, 2016, Ford notified ODI that it would conduct a safety recall (16V-643) to remedy the door latches in the MY 2012-2015 Ford Focus and other Ford models mentioned above (total of approximately 2 million vehicles).According to Ford, a component within the door latch may break preventing the door from latching.Ford dealers will replace all four door latches in the recalled vehicles with a new more robust latch design that is currently in production.The recall action initiated by the manufacturer appears to address the safety risks.Accordingly, this investigation is closed.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the identification (ODI) numbers found in the attached list.
