NHTSA Defect Investigations for the 2008 Ford Mustang

The Office of Defects Investigations (ODI) is an office within the NHTSA which investigates serious safety problems in the design, construction or performance of vehicles. The NHTSA is authorized to order manufacturers to recall and repair vehicles, if the ODI finds a safety issue. NHTSA investigations for the 2008 Ford Mustang, both ongoing and closed, are listed below:

  1. Air Bag Inflator Rupture NHTSA Engineering Analysis #EA15001

    • Status:
      OPEN
    • Date Opened: February 24, 2015
    • Date Closed: Pending
    • Recall: possible recall

    Component(s): Air Bags
    Air Bags:Frontal

    Summary: The Office of Defects Investigation (ODI) opened PE14-016 in June 2014 based on six inflator rupture incidents involving consumer owned vehicles produced by five vehicle manufacturers.All six vehicles were operated in Florida or Puerto Rico at the time of the rupture and for the majority of their service life, and were equipped with inflators produced by Takata, a tier-one supplier of automotive air bag systems.During the course of PE14-016, ODI determined that five additional vehicle manufacturers used inflators of a similar design and vintage also supplied by Takata. No evidence of field failures was found in vehicles produced by these five additional manufacturers.Nonetheless, at ODI's insistence, all 10 vehicle manufacturers initiated a regional recall within approximately two weeks of the opening of the investigation.The regions recalled initially included Florida, Puerto Rico, Hawaii, and the U.S. Virgin Islands, areas with high absolute humidity and climatic conditions believed to be a significant factor in the inflator ruptures.As part of the recall actions, inflators removed from remedied vehicles are to be returned to Takata for testing.Takata's initial test results on passenger inflators from remedied vehicles indicated a much higher than anticipated rupture frequency for inflators returned from Florida.Accordingly ODI requested all 10 manufacturers expand the regional recalls for passenger inflators to include other geographic areas where high absolute humidity conditions exist, including the Gulf States and other coastal areas.Takata's testing of the passenger inflators to date continues to indicate this geographic area as having the highest risk, with no ruptures occurring from inflators returned from outside the expanded recall regions.During PE14-016 four additional passenger inflator field events occurred, all in vehicles from the same expanded geographic region.Also during PE14-016 four additional driver inflator field events occurred including two in vehicles from regions not known for high absolute humidity, specifically California and North Carolina.Accordingly, ODI requested all five of the affected vehicle manufacturers currently using the subject Takata driver inflators expand to nationwide recalls.Significantly, neither of the affected vehicle manufacturers or Takata provided any explanation to account for these two driver air bag inflator ruptures outside the area of high absolute humidity.Takata testing of returned driver inflators indicates a lower rupture frequency as compared to passenger inflator testing.All test ruptures reported by Takata to date have occurred on inflators returned from high absolute humidity areas.The investigation now includes all manufacturers and vehicles known to be affected at this time.ODI's investigation will focus on, among other things, root cause analysis, other potential defect consequences, identification of affected vehicles scope, and adequacy of the remedy.The five ODI reports cited above can be reviewed online at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers: 10537899, 10568848, 10585224, 10605877, 10651492

  2. Air Bag Inflator Rupture NHTSA Preliminary Evaluation #PE14016

    Component(s): Air Bags
    Air Bags:Frontal

    Summary: The Office of Defects Investigation (ODI) opened PE14-016 in June 2014 based on six inflator rupture incidents involving consumer owned vehicles produced by five vehicle manufacturers.All six vehicles were operated in Florida or Puerto Rico at the time of the rupture and for the majority of their service life, and were equipped with inflators produced by Takata, a tier-one supplier of automotive air bag systems.During the course of PE14-016, ODI determined that five additional vehicle manufacturers used inflators of a similar design and vintage also supplied by Takata. No evidence of field failures was found in vehicles produced by these five additional manufacturers.Nonetheless, at ODI's insistence, all 10 vehicle manufacturers initiated a regional recall within approximately two weeks of the opening of the investigation.The regions recalled initially included Florida, Puerto Rico, Hawaii, and the U.S. Virgin Islands, areas with consistently high absolute humidity and climatic conditions believed to be a significant factor in the inflator ruptures.As part of the recall actions, inflators removed from remedied vehicles are to be returned to Takata for testing.Takata's initial test results on passenger inflators from remedied vehicles indicated a much higher than anticipated rupture frequency for inflators returned from Florida.Accordingly, ODI requested all 10 manufacturers expand the regional recalls for passenger inflators to include other geographic areas where high absolute humidity conditions exist, including the Gulf States and other coastal areas.Takata's testing of the passenger inflators to date continues to indicate this geographic area as having the highest risk, with no ruptures occurring from inflators returned from outside the expanded recall regions.During PE14-016, four additional passenger inflator field events occurred, all in vehicles from the same expanded geographic region.Also during PE14-016, four additional driver inflator field events occurred including two in vehicles from regions not known for high absolute humidity, specifically California and North Carolina.Accordingly, ODI requested all five of the affected vehicle manufacturers currently using the subject Takata driver inflators expand to nationwide recalls.Significantly, neither of the affected vehicle manufacturers or Takata provided any explanation to account for these two driver air bag inflator ruptures outside the area of high absolute humidity.Takata testing of returned driver inflators indicates a lower rupture frequency as compared to passenger inflator testing.All test ruptures reported by Takata to date have occurred on inflators returned from high absolute humidity areas.The PE is now closed/upgraded to an Engineering Evaluation (EA15-001) to include all manufacturersand vehicles known to be affected at this time.ODI's EA investigation will focus on, among other things, root cause analysis, other potential defect consequences, identification of affected vehicles scope, and adequacy of the remedy.The recalls related to this PE are: 14V343, 14V344, 14V348, 14V351, 14V353, 14V655, 14V700, 14V701, 14V752, 14V763, 14V770, 14V773, 14V787, 14V802 and 14V817.The number of vehicles affected are an estimate since some vehicles may have both the driver and passenger side inflators recalled. The five ODI reports cited above can be reviewed online at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification numbers: 10537899, 10568848, 10585224, 10605877, 10651492

  3. TIRE VALVE CRACKING NHTSA Preliminary Evaluation #PE08060

    • Status:
      CLOSED
    • Date Opened: October 14, 2008
    • Date Closed: April 09, 2009
    • Recall: no recall issued

    Component(s): Tires:Valve

    Summary: On October 14, 2008, ODI opened PE08-060 to investigate allegations of cracked and leaking snap-in tire valves in model year (MY) 2007 vehicles manufactured by Ford Motor Company.the valves were supplied to Ford by topseal auto-parts, a subsidiary of the shanghai baolong automotive corporation in china.valves made by topseal for aftermarket sale were the subject of two recent safety recalls by tech international (08T-018) and dill air controls (08T-028), the latter of which was investigated by ODI in PE08-036 and EA08-022.the defect conditions addressed by the aftermarket tire valve recalls both involved inadequate resistance to ozone cracking due to issues with the supply of anti-ozonant chemicals to topseal for a period from July to mid-November 2006.the aftermarket valves were compounded with a blend of epdm and natural rubber, using a relatively low percentage of epdm (epdm provides inherent resistance to ozone cracking).hence, the need for anti-ozonant chemicals and the problems with cracking when those chemicals were missing or out of specification in some lots of valves.both recall campaigns involved inspection programs to identify and replace valves with visible surface cracking.although the topseal valves supplied to Ford also appear to have been affected by the anti-ozonant supply issues in mid to late-2006, Ford indicated that its valves were made at a different topseal production line and were compounded with a higher percentage of epdm rubber to meet more stringent specifications from Ford.ODI's analysis of complaint and warranty data provided by Ford showed that problems with cracked tire valves were significantly higher for MY 2007 vehicles produced from December 2006 through March 2007.Ford responded by implementing changes in its material specifications for snap-in rubber tire valves and also increasing the quality and acceptance standards for valves imported for use in its vehicles.while the complaint and warranty claim rates are elevated for subject vehicles produced from December 2006 through March 2007, the rates of leaking valves are well below one percent of production for each of the peak months for all of the affected models.a substantial majority of the subject vehicles are equipped with tire pressure monitoring systems (TPMS) which warn the driver when any tire pressures drops below 25 percent of recommended inflation pressure. As outlined in a letter to ODI dated April 6, 2009, Ford has agreed to send letters to owners of certain MY 2007 and 2008 Ford, Lincoln and Mercury vehicles to provide information about the cracking concern. Letters will be sent to owners of vehicles built from November 2006 through May 2007.owners can opt for a free dealer inspection.valves exhibiting surface cracks or air leakage related to ozone attack will be replaced by Ford under its normal warranty terms.Ford expects to send the letter by approximately mid-May 2009. Based on the use of TPMS in the majority of subject vehicles and the relatively low rates of repairs associated with leaking valves and resultant tire damage, ODI believes that the actions Ford has agreed to take will provide effective and expeditious resolution for vehicles that were built during the period when valves with inadequate resistance to ozone cracking were most likely to have been used in vehicle production.further investigation of this matter would not be an efficient allocation of Agency resources.accordingly, this investigation is closed.the closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.the Agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.

  4. Fleet Vehicle Recall Completion Audit NHTSA Defect Investigation #AQ10001

    • Status:
      CLOSED
    • Date Opened: November 18, 2010
    • Date Closed: December 28, 2015
    • Recall: no recall issued

    Component(s): Unknown Or Other

    Summary: On November 18, 2010, NHTSA's Recall Management Division (RMD) opened an audit query (AQ10-001) to investigate recall remedy completion by rental car companies on safety recall campaigns.It was expected to provide the agency an indication of how completely and how quickly rental car fleets perform necessary recall-related remedies on the vehicles owned and then rented/leased for use on the roadways.RMD queried three (3) major motor vehicle manufacturers (Ford, Chrysler, and General Motors) and requested data regarding completion figures for fifteen (15) discreet safety recalls.Analysis of this data demonstrated that rental car recalls completion was neither complete nor consistent.The rental car companies representing the largest market share in the industry were then queried as to their respective policies for the rental, lease, and sale of vehicles with open recalls.The data and responses from the manufacturers and the rental car companies can be found in the document repository by accessing the ""Associated Documents" link above.In December 2015, Congress enacted the Fixing America's Surface Transportation (FAST) Act.One section of the Act prohibits rental car companies from renting, leasing, or selling motor vehicles subject to open safety recalls.With the passage of the FAST Act and its prohibition, there is no continuing need for the agency to investigate rental car recall completions.Accordingly, this investigation is closed.The agency reserves the right to open any future investigations, including audits of individual recalls, or groups of recalls, or rental car companies, to examine more closely safety recalls performance and completion issues in this area.
