NHTSA Defect Investigations for the 2010 Jeep Wrangler

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 2010 Jeep Wrangler, both ongoing and closed, are listed below:

  1. Air Bag Clockspring Wiring Failure NHTSA Preliminary Evaluation #PE15025

    • Status:
      CLOSED
    • Date Opened: June 19, 2015
    • Date Closed: December 07, 2015
    • Recall: no recall issued

    Component(s): Air Bags
    Air Bags:Frontal

    Summary: In it's response to ODI's PE15-025 Information Request letter, FCA identified 1,703 consumer complaints, field reports and legal claims responsive to the subject defect condition on the subject Wrangler vehicles.Six of these reports alleged an air bag non-deployment in a crash in which either the air bag warning light was allegedly on or came on afterward the crash, one of which also alleged injuries as a result of the non-deployment.FCA also provided data on other make, model and model year vehicles using the same clockspring.Additionally FCA provided 16,955 warranty claims related to the replacement of the air bag clockspring wiring assembly.It should be noted that FCA initiated an Extended Warranty Program on the left hand drive MY 2007 Wrangler in late calendar year 2011.6,777 of these claims are from the MY 2007 left hand drive Wrangler.FCA advises that some of the warranty claims involved clockspring failures that would not affect the air bag operation, for example due to noise, cruise control and/or radio operation issues.Many of these claims involved newer model year subject vehicles.FCA also noted that Wrangler's removable roof and door configuration may make it more susceptible to outdoor water/moisture and dust ingress.ODI investigated the right hand drive Wrangler in calender year 2011 for a similar clockspring issue under PE11-019.That investigation lead to NHTSA Safety Recall 11V258 on right hand drive model year (MY) 2008-2012 Wranglers.FCA redesigned the remedy clockspring to improve its durability and environmental protection and revised the design of the steering wheel to column shroud.Base on the data reviewed, this Preliminary Analysis (PE) is being upgraded to an Engineering Analysis (EA).The reports cited above are listed in the public investigative file available at SaferCar.gov under this investigation ID.

  3. Totally Integrated Power Module Failure NHTSA Defect Investigation #DP14004

    • Status:
      CLOSED
    • Date Opened: September 25, 2014
    • Date Closed: July 24, 2015
    • Recall: no recall issued

    Component(s): Electrical System

    Summary: 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 the subject vehicles equipped with TIPM-7. Approximately 3 percent of CAS complaints are related to vehicles equipped with TIPM-6 and ODI-s review of these complaints did not identify any safety defect trends. ODI conducted a detailed review of complaints narratives submitted by CAS and consumers including careful analysis of vehicle repair histories, warranty claims obtained from the manufacturer and any available Customer Assistance Inquiry reports (CAIR). Analysis of the field data indicated that MY2011-2013 Jeep Grand Cherokee and Dodge Durango vehicles exhibited significantly higher complaint rates related to fuel pump relay (FPR) failures than other subject vehicles. In a September 3, 2014 letter to NHTSA, Chrysler submitted a Defect Information Report (DIR) identifying a defect in the FPR within the TIPM-7 which can result in a no start or stall condition in approximately 188,723 model year (MY) 2011 Jeep Grand Cherokee (WK) and Dodge Durango (WD) vehicles manufactured from January 5, 2010 through July 20, 2011 (14V-530).In a February 24, 2015 letter, Chrysler submitted a second DIR expanding the scope of the FPR defect condition to include an additional 338,216 MY 2012 through 2013 Jeep Grand Cherokee vehicles manufactured from September 17, 2010 through August 19, 2013 and MY 2012 through 2013 Dodge Durango vehicles manufactured from January 18, 2011 through August 19, 2013 (15V-115).ODI analysis of the CAS allegations of TIPM defects resulting in stall while driving, airbag non-deployment, unintended acceleration, fire and other faults identified a single defect condition related to 1 of over 60 different circuits in the TIPM assembly. The most common effect of this defect condition, related to the fuel pump relay, was a no-start concern, but it could also result in stall while driving (76 complaints). No valid evidence was presented in support of claims related to airbag non-deployment, unintended acceleration or fire resulting from TIPM faults and these claims were found to be wholly without merit based on review of the field data and design of the relevant systems and components.Except insofar as the petitioner's contentions relate to the defect condition addressed by the Chrysler recalls, the factual bases of the petitioner's contentions that any further investigation is necessary are unsupported. In our view, additional investigation is unlikely to result in a finding that a defect related to motor vehicle safety exists or a NHTSA order for the notification and remedy of a safety-related defect as alleged by the petitioner at the conclusion of the requested investigation. Therefore, in view of the need to allocate and prioritize NHTSA's limited resources to best accomplish the agency's safety mission, the petition is denied. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency will take further action if warranted by future circumstances. Please see the Federal Register notice in DP14-004 file (www-odi.nhtsa.dot.gov/defects).

  4. Skid plate debris fires NHTSA Preliminary Evaluation #PE12009

    Component(s): Engine And Engine Cooling
    Power Train:Automatic Transmission

    Summary: In a letter dated May 15, 2012, the Chrysler Group LLC (Chrysler) submitted a Defect Information Report to NHTSA identifying a safety defect regarding fires originating between the transmission skid plate and the exhaust catalyst in approximately 65,246 model year (MY) 2010 Jeep Wrangler 4x4 vehicles with automatic transmissions (NHTSA Recall 12V-216).According to Chrysler, changes to the exhaust system for MY 2010 resulted in reduced clearances between the exhaust catalyst and the skid plate.If debris collects in the area of the skid plate and is not removed, there is an increased potential for underbody debris fires.ODI's analysis of skid plate area fires in the MY 2010 Wrangler vehicles with automatic transmissions found that the rate increased significantly from approximately 1.7 fires per 100,000 vehicle years in the MY 2007 through 2009 vehicles with the prior exhaust design to approximately 14.8 fires per 100,000 vehicle years in MY 2010 vehicles, a nearly 800 percent increase.In analysis of both Vehicle Owner Questionnaire (VOQ) data submitted to the Office of Defects Investigation (ODI) and Chrysler's consumer complaint data submitted to ODI, 35 unique reports were identified by Chrysler alleging fire in subject vehicles with origins near the engine compartment or in the underbody area directly beneath and to the rear of the engine compartment.Chrysler's assessments of the 35 reports of fire were categorized by likely causes.Eleven of the fires were determined to be caused by skid plate debris accumulation and 4 additional fires were found to have originated in the area of the skid plate, but debris ignition could not be confirmed.An additional skid plate debris fire was reported to ODI after the recall announcement, bringing the total known fire count to 36, including 12 caused by skid plate debris and 4 originating in the skid plate area from unknown causes.Chrysler identified a design change to the exhaust system in MY 2010 that increased the possibility of debris contact with an exhaust catalyst.Beginning in MY 2011, the skid plate was replaced with a skid bar for weight reduction purposes.The skid bar having a much smaller surface area than the skid plate reduces the potential for debris entrapment.The recall remedy for recall 12V-216 will involve replacement of the skid plate with the skid bar.As background, the MY 2010 subject vehicles are a part of the JK generation of Jeep Wrangler vehicles that began production in MY 2007.Chrysler conducted a prior recall (09V-436) of MY 2007 and 2008 Jeep Wranglers for a defect involving overheated transmission fluid expulsion that could contact the exhaust and cause an engine compartment fire.The recall remedy was to add audible (chime) and visual warnings ("hot oil" message in the instrument cluster) to alert the driver that the vehicle was being operated with elevated transmission fluid temperatures.Chrysler enhanced the audible warning with a service campaign (J31) for MY 2009 and a portion of the subject MY 2010 vehicles.Transmission fluid expulsion has not been identified as the cause of any of the 36 fire incidents in the subject vehicles. No indications of a common causal pattern were evident in the remaining 20 fire incidents in the subject vehicles.Six (6) of the incidents appear to be related to improper wiring of various added aftermarket equipment, 2 appear to be related to improper oil change, 1 was related to a damaged transfer case, 1 was related to an electrical short circuit and the remaining 10 were of unknown origin.Accordingly, this Preliminary Evaluation is closed.The ODI reports cited above can be reviewed at www-odi.nhtsa.dot.gov/owners/SearchNHTSAID under the following identification (ODI) numbers:Skid plate debris fires:10460378, 10441570, 10421483, 10406886 Underbody fire, skid plate debris unconfirmed:104515170
