2018 Jeep Wrangler

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.

On September 16, 2019, the Office of Defects Investigation (ODI) granted Defect Petition DP18-004 and opened Preliminary Evaluation PE19-012 to investigate allegations of deficient frame welds and their potential safety related effects on 2018-2019 Jeep Wranglers. Due to a previous steering related recall that was caused by a misaligned weld on the front track bar (NHTSA Recall No. 18V-675), ODI decided to include reports of steering shimmy or wobble, loose steering, and steering stiction (loss of power steering) as part of this investigation and parent petition (DP18-004). ODI received information from the vehicle manufacturer Fiat Chrysler Automobiles (FCA) via information request letters dated March 8, 2019, and February 6, 2020. Supplemental requests for information occurred between July 2020 and July 2023. A review of the responsive manufacturer information showed that vehicles presenting an unexpected reduction in steering ability due to a welding tool misalignment were correctly addressed via recall 18V-675. General complaints concerning the weld appearance were not associated with a realized risk to motor vehicle safety. ODI identified a limited number of reports involving weld separation on vehicles that were out of scope of recall 18V-675. FCA identified various causes of weld quality issues in early production (build dates prior to March 2018) including improper welding techniques on galvanized frames and component part variation leading to off-seam welds. These issues were addressed in production for subject vehicles built after July 2018 and preceded a drop in weld failure reports. ODI reviewed manufacturer and agency reports of weld failures out of scope of recall 18V-675 and did not find any that resulted in a loss of vehicle control. There are no known crashes, injuries, or fatalities as a result of weld failures on vehicles not included in recall 18V-675. Due to the steering related consequence associated with Recall 18V-675, ODI opted to include a request for information regarding various steering issues experienced by vehicles included in this investigation. ODI reviewed manufacturer as well as agency data and determined these various steering issues were not related to any weld defect. Since the opening of this investigation, FCA has addressed the following steering concerns; a. Steering looseness due to material choice in the steering box internal components. FCA released an updated part with an internal component material less sensitive to temperature variances (TSB 08-003-21 REV. A).NHTSA will take further investigative action if justified. b. Steering wobble or shimmy due to a manufacturing and design deficiency in the steering damper. FCA released a part via Customer Satisfaction Notification (CSN) V41 in June 2019 which implemented supplier quality control improvements and design changes due to the presence of air in the base valve which degraded damping performance.NHTSA will take further investigative action if justified. c. Steering stiction, or loss of power steering, due to an underpowered steering pump calibration that occurred at highway speeds during cold weather. In December 2021, FCA released CSN Y95 which corrected this issue via software update. Due to the decreased number of consumer complaints, the service campaign appears to have addressed the issue related to an underpowered steering pump. NHTSA will take further investigative action if justified. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency reserves the right to take additional action if warranted by future circumstances.

On July 17, 2019, NHTSA's Office of Defects Investigation (ODI) opened Preliminary Evaluation (PE) 19-008 after receiving three Vehicle Owner Questionnaire (VOQ) reports alleging the driver's side seat belt buckle separated from the seat frame, rendering the seat belt non-functional. The VOQs involved model year (MY) 2015 and 2016 Jeep Wrangler (JK platform) that were configured for right-hand drive (RHD) use. On August 8, 2019, ODI issued an information request (IR) letter to FCA.The scope of the IR included all JK Wrangler produced for sale in the U.S. (both left- and right-hand drive), and amongst other things, requested any reports or allegations of driver's seat belt bracket failures on these vehicles. In its review of FCA's response, ODI determined that approximately 1.7 million JK Wrangler were produced from MY 2007 to 2018, about 16,000 of which were configured for RHD. ODI notes that the RHD Wrangler are typically used for rural postal delivery which often experience a more severe duty cycle. Also RHD JK was was not produced in MY 2007.As explained in the IR response, FCA identified three distinct populations of JK Wrangler concerning the driver's seat belt bucket bracket; specifically the MY 2007-2018 LHD (~1.7M units), the MY 2008-2010 RHD (4,563 units), and the MY 2011-2018 RHD (11,463 units) populations.FCA provided details on the designs used in each of these populations, identifying specific differences deemed pertinent to the strength and durability of each unique bracket design. FCA further reviewed its analysis of the complaint and warranty data identified under the IR, and noting that it had not identified any allegations of bracket failures on the LHD population, and only one allegation on the MY 2008-2010 RHD vehicles. By comparison, FCA identified 24 allegations of bracket failure for the MY 2011-2018 RHD JK, including two reports duplicative of the VOQs. Neither the FCA nor the VOQ reports allege an injury or fatality due to bracket failure. Based on this analysis, FCA decided to conduct a safety recall for the MY 2011-2018 RHD JK population. On September 30, 2019, FCA submitted a Defect Information Report initiating NHTSA Safety Recall 19V-680 (FCA No. VA6). Under the recall action, FCA will replace the driver's seat belt bracket on MY 2011-2018 RHD Jeep JK Wrangler. The repair will be conducted free of charge.In view of FCA's recall action, and its explanations of the scope of that action, ODI is closing PE19-008. ODI will continue to monitor the non-recalled RHD, and the LHD JK Wrangler for evidence of seat belt bracket failure and will take further action if warranted.The three VOQ reports cited above can be reviewed at NHTSA.gov under the following reference numbers:11190251, 11218472, 11231639.

The Office of Defects Investigation (ODI) opened this investigation to determine if the failure of airbags to deploy during severe crashes, in certain vehicles, was the result of a safety related defect.  During the investigation a complex failure was studied that can result in non-deployment of subject vehicle air bags and other restraint system devices in severe crash events. The subject vehicles may be equipped with an airbag control unit (ACU) for the supplemental restraint system (SRS) Electronic Control Unit (ECU) manufactured by ZF-TRW.  The ECU receives signals from crash sensors mounted in the vehicle and deploys the vehicle air bags and seat belt pretensioners in accordance with manufacturer design specifications.  The ECU in the subject vehicles contains a model DS84 application-specific integrated circuit (ASIC) which controls the communication of the crash sensor signal, firing commands (i.e., when to deploy the airbag(s) and/or pretensioners), and fault information (e.g., diagnostic trouble codes). In September 2016, FCA announced recall 16V-668 for certain model year (MY) 2010 to 2014 Chrysler, Dodge and Jeep products manufactured with the subject ZF-TRW ACU.  In this recall, FCA discussed an EOS condition that resulted in a failure of the subject DS84 ASIC, which caused air bag non-deployment.  FCA noted that the defect condition had only been observed in vehicles equipped with sensor harnessing routed across the front of the vehicle.  Other FCA vehicles that also used the subject ACU, but were not equipped with cross-car harnessing, had not experienced EOS failures, despite similar time in service. During the course of this investigation, ODI sent two separate Information Request (IR) letters to six vehicle manufactures (including FCA, Hyundai, Honda, Kia, Mitsubishi, and Toyota) and one IR letter to ZF-TRW.  These IR letters resulted in ODI receiving comprehensive data from these manufacturers and suppliers. Studies of this data found that the DS84 ASIC does not have sufficient protection against negative electrical transients or electrical overstress (“EOS”) that can be generated in certain severe crashes.  An electrical transient occurs when the electrical power supplied to a circuit changes momentarily over a short duration of time.   In these severe crash cases, the crash sensors and other powered wiring can be damaged and short circuited so as to create a negative electrical transient of sufficient intensity and duration (that are outside the vehicle manufacturer's specification) to damage the ASIC before the restraint device deployment signal is received by the SRS ECU.  This damaged signal can lead to incomplete or nondeployment of the air bags and/or pretensioners.  Airbag non-deployment and/or lack of pretensioner operation can increase the risk or severity of injury in a crash.A total of 8 fatalities and 14 injuries were associated with known EOS events. The common element in all investigated manufacturers vehicles is the SRS ECU containing a DS84 ASIC manufactured by ZF-TRW.  The risk associated with the ASIC is equally shared among all OEMS involved in the investigation.  The actual real-world risk can be mitigated by other factors which were assessed by ODI during this investigation. The first mitigating factor involves protections built into the ACU design which protect the DS84 ASIC from damage.  There are multiple strategies and levels of protection employed by different OEMs that provide effective EOS mitigation.  The two most common strategies at the ACU level are circuit protection diodes on the remote senor signal lines, and current limiting resistors that protect critical components. The second mitigating factor is found at the vehicle level and involves the location and routing of the wires leading from the crash sensors to the SRS ECU.  If the wires are well protected in a crash and are not routed with other power wires carrying large currents, the risk for an EOS event is significantly reduced or eliminated. These design specific factors combine to produce a spectrum of risk for the vehicles equipped with ACUs using the DS84 ASIC.  Given the many of years of field exposure, it is possible to divide the subject population into two groups; vehicles which have experienced EOS events, and vehicles which have not experienced EOS field events. Four of the six OEMs involved in this investigation have experienced EOS field events on at least one of their models equipped with a DS84 ASIC.  All vehicle models (including the Toyota models identified in the Failure Report Summary of the opening resume for this investigation) with field events have been recalled.  In an abundance of caution, ODI kept this investigation open five years to monitor field performance and did not identify any field events on vehicles not included in existing safety recalls. Given the spectrum of risk identified in this investigation and that all vehicles with a demonstrated unreasonable risk have been recalled, ODI is closing this investigation. ODI is closing this investigation with the following manufacturer safety recalls: 16V-668, 18E-043, 18V-137, 18V-363, and 20V-024.  With the recall actions taken by the subject vehicle and equipment manufacturers, this investigation is closed. The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exists on other model or model year vehicles outside of the recall scopes. The agency reserves the right to take further action if warranted by the circumstances.

I had Recall issue occur on my 2018 Jeep Wrangler JLU #19A Clutch Assembly. The issue also damaged the Transmission as stated possible in the recall. Additionally the dealership reported that recall required replacement of the cluster (Instrument cluster with all gauges). This was all done. However, upon picking up the jeep and driving home, I realized that the cluster was no longer showing what gear the car is in. I called and reported to the dealer. They asked me to bring in as they though might be a software update or something, they would hook to machine. In the meantime the jeep started experiencing issues where every emergency light on cluster would go off. I would lose power steering, and I could not even turn the car off. I had to stall the car to get engine to stop. I took back to dealer (Cherry Hill Jeep) the reported the "star connector" or Can C-Bus Connector needed to be replaced. I explained that this never occurred prior to recall issue so it must be covered. they said they did not know. They replaced. I went to pick up and still the car did not show the proper gear. after further review by the dealer, they believe they received and installed the wrong cluster. This cluster now caused a problem with the Can C-Bus connector, and the car still does not show what gear it is in. All cars show what gear the car is in. this jeep currently does not. the dealer claims that the software update does not include the gear. This is not how i purchased the car or how i dropped it off prior to recall issue. Dealer is trying to charge me for labor of Can C-Bus connector and install for over $1000 and the car still does not show the gear. I have claim with Stallantis #98090202 they keep pointing to dealer. Dealer keeps pointing to Stallantis. A car must show the gear. This is safety concern to drive the car.

FCA US LLC is actively violating the intent of Safety Campaign 23V-116 by refusing to cover out-of-pocket consequential transmission damages. FCA’s own Part 573 Defect Report explicitly admits that the defective clutch pressure plate causes extreme friction, overheating, and fracturing capable of damaging the transmission case and nearby internal components. The vehicle operated under these defective parameters prior to the recall execution, subjecting the transmission internals to progressive thermal fatigue and severe structural vibration. This directly induced a premature internal mechanical failure less than 9,000 miles after the recall was performed. When a reimbursement claim was submitted for this consequential damage, Jeep Customer Care explicitly denied the claim under a corporate case file, stating the transmission components "are not covered under the recall repair," completely ignoring FCA's own federal defect acknowledgments. I am requesting a federal investigation into FCA’s systemic refusal to cover consequential powertrain failures caused by this safety defect.

2018 Jeep Wrangler rubber brake lines collapsing internally, trapping hydraulic fluid pressure, and causing front brakes to overheat/lock up. Happened last year on my driver's side. It completely locked up my caliper. Ended up replacing Front Driver Hose & Caliper. And both Front Rotors and Brake Pads. Now its currently happening to my passenger side. This time its actually causing a burning smell. Last year it did not it was just grinding. Been for a few months. At first I though it was my aux battery that was dead and was causing the smell. But got that looked at and didnt even have a ln aux battery. Didnt notice the smell for a few months. But now in extreme heat and worsen driving conditions it has came back. Was told my hose is collapsing. So now I have to replace rotors and brake pads again. And new hose and caliper on my passenger side

The contact owns a 2018 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, there was an abnormal burning odor inside the vehicle. No warning lights were illuminated. In addition, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The vehicle was taken to the dealer, and the contact was informed that parts for a recall repair might have been replaced with defective parts. The contact was informed that there was no failure and the vehicle was released; however, the failure reoccurred. The vehicle was taken back to the dealer, where it was confirmed that the clutch was slipping. The contact was informed that the clutch needed to be adjusted. The vehicle was repaired, but the failure reoccurred. The vehicle was taken to the dealer, and the contact was informed that the failure was because the contact was changing gears at 2,000 RPM and the gears should be shifted at 2,500 RPM. The vehicle was taken to an alternative dealer where the contact was informed that the recall repair was completed incorrectly. The contact was informed that the recall repair needed to be performed a second time. The vehicle was not repaired. The contact received notification of NHTSA Campaign Number: 23V116000 (Power Train). The contact stated that the vehicle was experiencing the failure prior to the recall repair, but the failure became more persistent after the recall repair was completed. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that a second recall repair was denied. In addition, the contact was advised to take the vehicle to the initial dealer for a diagnostic test. The failure mileage was approximately 23,050.
