NHTSA Defect Investigations for the 2001 Honda Accord

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 2001 Honda Accord, 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

    • Status:
      CLOSED
    • Date Opened: October 30, 2014
    • Date Closed: April 21, 2016
    • Recall: no recall issued

    Component(s): Air Bags

    Summary: In a Consent Order executed on December 29, 2014, American Honda Motor Co. ("Honda") admitted that it violated the Safety Act by failing to report certain death and injury incidents that were required to be reported to NHTSA under 49 C.F.R. 579.21(b), and by failing to report certain customer satisfaction campaigns, special warranty extensions, and warranty claims that involved goodwill, third-party vehicle service contracts, or Honda-certified, pre-owned vehicles, as required by 49 C.F.R. 579.21(c).As part of the Consent Order, NHTSA assessed a total civil penalty of $70 million against Honda for its violations of the TREAD Act and associated regulations. Honda timely paid the civil penalty in full on January 20, 2015. Honda also agreed to develop written procedures for comprehensive early warning reporting in compliance with 49 C.F.R. Part 579, Subpart C; to train appropriate personnel on its early warning reporting requirements and written procedures; and to complete two third-party audits of its TREAD Act reporting.NHTSA opened this audit query (AQ) investigation in order to investigate the extent and scope of Honda's failure to report early warning information pursuant to the TREAD Act, as well as the reason(s) for such failures and the steps being taken by Honda to assure full compliance with TREAD reporting requirements.Based on the Consent Order, Honda's admissions that it violated the law, and the completion of its performance obligations, this audit query, AQ14-004, is closed. Closure of this AQ has no bearing on the terms of the Consent Order and does not represent a determination by the Agency as to Honda's performance under the Consent Order.

  3. 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

  4. RUPTURING DRIVER'S AIR BAG INFLATORS NHTSA Defect Investigation #RQ09004

    • Status:
      CLOSED
    • Date Opened: November 02, 2009
    • Date Closed: May 06, 2010
    • Recall: no recall issued

    Component(s): Air Bags
    Air Bags:Frontal
    Air Bags:Frontal:Driver Side Inflator Module

    Summary: This RQ investigation was opened to collect and analyze additional information to better evaluate the scope and timeliness of Honda's two safety recalls addressing rupturing of the driver's side air bag inflators (08V-593 and 09V-259).In an earlier response to RMD's request for information, Honda indicated that the second recall (09V-259), essentially an expansion of the first (08V-593), was necessary since later information informed that the source of the defect was different than originally postulated, and so the scope of the vehicles affected changed. Honda indicated that it had relied on its supplier of the air bag inflators, Takata, Inc. (Takata), in studying the possible sources of the inflator ruptures and identifying the recall populations.Accordingly, RMD issued a request forinformation to Takata on November 20, 2009, and Takata provided a partial response on December 23, 2009.Takata then provided its complete response on February 19, 2010.Takata informed ODI that, after analysis of several ruptured inflators, Takata and Honda initially attributed the defect to handling of the propellant during inflator assembly that could have yielded increased moisture levels that, when coupled with thermal cycling in automobiles over time, could lead to reduced propellant density and overly aggressive combustion during air bag deployment.However, it discovered upon review of inflators returned from the 08V-593 recall campaign, some of which fell outside the manufacturing range when Takata suspected the propellant was exposed to elevated moisture, that the source of the defect was more likely due to problems with a specific compression press (Stokes press) used to form the inflator's propellant.Specifically, the propellant tablets produced by the press were found to be less dense, and therefore more susceptible to overly aggressive combustion during air bag deployment.Takata identified the manufacturing time frame over which the tablets were shown to have less dense properties as the end of calendar year 2000. Takata informed Honda of its discovery on or about June 12, 2009.Honda made its defect decision and then notified NHTSA of it on June 30, 2009.Honda then supplemented its filing with an identification of the specific vehicles to be included in the campaign, as well as identifying additional models to be included, on July 29, 2009.As with the 08V-593 campaign, Takata examined inflators returned from the 09V-259 campaign, and some of which were manufactured outside of the range when the Stokes press was found to have produced less dense propellant (beyond the end of February 2001).It provided those findings to Honda and Honda decided to expand safety recall 09V-259 to include all vehicles with inflators containing propellant manufactured using the Stokes press.Honda notified NHTSA of its decision on February 9, 2010.Based upon all available information, there is insufficient information to suggest that Honda failed to make timely defect decisions on information it was provided.Also, given that all inflators with propellant manufactured using the Stokes press have been recalled, there are no additional vehicles to be investigated and campaigned.Accordingly, this RQ is closed.

  5. SRS READINESS INDICATOR ILLUMINATION NHTSA Preliminary Evaluation #PE05043

    • Status:
      CLOSED
    • Date Opened: August 12, 2005
    • Date Closed: March 24, 2006
    • Recall: no recall issued

    Component(s): Air Bags:Frontal:Sensor/Control Module
    Air Bags:Side/Window

    Summary: The subject vehicles are designed with an occupant position detection system (opds) for the passenger seat to suppress the side airbag in the event of an out-of-position occupant.on some vehicles, the opds unit and sensor grid may be susceptible to high moisture content and/or to sporadic electrical interference that would result in the illumination of the SRS readiness indicator.in this condition, opds suppression will not function, but the side airbag will still deploy in the event of a side crash. Honda issued a technical service bulletin in April 2004 to address this problem. However, the problem persists even after the warranty period expires.as a result, some owners may not be obtaining the necessary remedial service work.continued illumination of the SRS indicator can "mask" the detection of other airbag component faults if they occur. In March 2006, Honda issued a service bulletin (06-009) to extend the warranty on SRS illumination and opds issues to 10 years or 150,000 miles (whichever occurs first).Honda will send notification letters to owners of the subject vehicles and will provide a no cost replacement of the opds unit as needed.in addition, other MY 1999-04 Honda and Acura vehicles are also covered by the bulletin.this action taken by the manufacturer is sufficient to resolve the issue raised by this investigation.the closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.the Agency reserves the right to take further action if warranted by the circumstances.

  6. IGNITION-PARK INTERLOCK NHTSA Preliminary Evaluation #PE05002

    Component(s): Electrical System
    Electrical System:Ignition
    Electrical System:Ignition:Switch

    Summary: The above failure report counts are for model year (MY) 1999 - 2001 Honda Accord models that were not within the scope of a related Honda recall action (NHTSA 03V423); these vehicles were investigated by ODI under defect petition (dp) 04-006.complaint information for other models and model years was not obtained by ODI.the noted population indicates the number of vehicles (including the MY 2002 Accord plus the Prelude and TL models) that are within the scope of Honda's new recall (NHTSA 05V-025, Honda P68, P69); 402,525 of these were investigated in DP04-006.seepart 573 documents related to 05V-025 for further detail on other models and MYs.ODI notes that, according to Honda's analysis, interlock system warranty rates for the TL and Prelude models involved in 05V-025 are similar to those of the Accord models.information provided by Honda during DP04-006 indicates that certain vehicles containing interlock systems made by its Japanese lock manufacturing facility may contain defective internal components.in combination with certain wear and usage factors, this may lead to a condition that prevents the system from blocking removal of the ignition key when the vehicle is not in park.if the driver leaves the transmission in a non-park position and fails to set the hand brake when parking, the vehicle may roll away and crash.interlock systems manufactured by Honda's U.S. lock manufacturer do not appear to contain this defect and are therefore not included in the recall action. In a letter dated January 27, 2005, Honda advised that it will conduct a safety recall to either upgrade (for operative systems) or repair (for inoperative systems) subject interlock systems with new design level components that do not contain the defect.

  7. IGNITION-PARK INTERLOCK NHTSA Defect Investigation #DP04006

    • Status:
      CLOSED
    • Date Opened: October 08, 2004
    • Date Closed: January 13, 2005
    • Recall: no recall issued

    Component(s): Electrical System:Ignition
    Electrical System:Ignition:Switch

    Summary: The Office Of Defects Investigation (ODI) produced an information request (ir) letter dated October 14, 2004 which defined the subject vehicles as model year 1999 - 2001 Honda Accord vehicles which were not within the scope of prior recall action (03V423) Honda conducted to resolve an interlock defect.Honda submitted responses on November 29 and December 21, 2004.the failure reports noted above have been determined from ODI's analysis of NHTSA's complaint database and an initial analysis of the manufacturer's ir response data (further analysis required).some of the Honda reports are duplicative of ODI.taking into account a shorter service life, the failure incidence of the subject vehicles is similar to that determined when ODI conducted preliminary evaluation (PE) 03-013, which involved interlock failures on older Accord subsequently recalled under the 03V423 action.accordingly, the petiton is granted and ODI has opened PE05-002 to further investigate the matter.

  8. IGNITION-PARK INTERLOCK NHTSA Engineering Analysis #EA03017

    Component(s): Electrical System:Ignition:Switch
    Power Train:Automatic Transmission:Gear Position Indication (Prndl)

    Summary: Six of the ODI complaints are duplicative of Honda complaints, as well as four of the crashes.the one injury occurred when a rollaway vehicle struck the exiting operator who had inadvertently parked the vehicle in an unsecured state (not in park, brake not engaged).Honda identified the warranty claims from complaint descriptions that contended the interlock system failed to operate properly.Honda presented the results of their investigation into interlock system failures at an October 16, 2003 meeting with ODI in which Honda identified a supplier and an engineering specification change for the ignition cylinder body (cb), a subcomponent of the ignition lock assembly.results from Honda's analysis demonstrated a strong correlation between the production date range of vehicles that experienced higher interlock warranty claim rates and the implementation dates of the changes.an engineering specification for a surface treatment process for the cb was eliminated at the beginning of MY 1998.the supplier of the cb was changed in February 1999.vehicles built within this time period contain a cb with poor surface hardness that can wear prematurely.as the wear progresses, the interlock system becomes incapable of preventing key removal when the shifter is in a non-park position.interlock failure increases the risk of a vehicle rollaway and subsequent crash or injury when vehicles are parked unsecured.Honda Accord vehicles subject to this change include MY 1998 and MY 1999 through February 1999 production.vehicles produced after this date are not affected by this condition and thus are not considered at risk for failure.ODI notes that 12 of the 13 voq reports fall within this production range (the 13th does not have a VIN and cannot be verified).the above population represents the number of the Accord vehicles to be recalled.Honda also reported that certain Odyssey and Acura cl and TL models were affected and would also be recalled.a total of 570,120 vehicles will be recalled.under recall 03V-423, Honda will inspect vehicles and replace components (including the cb) on vehicles with excessive wear.vehicles not showing wear will have a redesigned part installed which prevents wear.

  9. SEAT FRAME BRACKET FAILURE NHTSA Preliminary Evaluation #PE02072

    • Status:
      CLOSED
    • Date Opened: October 02, 2002
    • Date Closed: March 28, 2003
    • Recall: no recall issued

    Component(s): Seats

    Summary: This PE was opened based on 10 consumer complaints in the ODI database alleging that the power assisted seats were failing in certain 1998-2002 Honda Accord vehicles.failures are concentrated in the 1998-99 model year vehicles.the bracket that attaches the seat bottom to the seat base is fracturing due to: 1-the weld condition of bracket, 2-the drivers weight, and 3-the impact on the seat when the driver enters the vehicle and sits down.over time the bracket that attaches the seat may fail at the left front corner of the seat bottom.the other 3 points of attachment of the seat bottom to the seat base stay attached and the seat movement is limited.the attachment of the seat bottom to the seat back does not fail.the condition is most apparent during rapid acceleration causing the seat to tilt rearward.although a few complaints report concern over loss of vehicle control, no loss of control incidents, crashes or injuries are reported.in response to customer complaints, Honda will provide owners of 1998 and some 1999 Accord a no-cost reinforcement for the seat at the left front corner.a safety-related defect has not been identified at this time and further use of Agency resources does not appear to be warranted.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 take further action if warranted by the circumstances.
