I am writing to formally express my deep concern and frustration regarding the persistent electrical issues with my 2017 Jeep Patriot, which I purchased in November 2018 with approximately 18,000 miles. Just two days after purchasing, I began experiencing electrical malfunctions. I returned to the selling dealership, who claimed they found no issue but performed a tune-up. Over the years, the problems persisted, and despite numerous visits to authorized dealerships, I was repeatedly given temporary repairs with no permanent resolution. Eventually, a recall was issued, but by that time, I was told the vehicle was no longer under warranty — despite the fact that I had reported the issue early and consistently. I have spent thousands of dollars trying to resolve these electrical faults, with no lasting fix. Most recently, I brought the vehicle to a trusted dealership who confirmed an electrical issue, but informed me the required part has been discontinued. I have also learned that many other Jeep Patriot owners have experienced similar electrical issues. Some have returned or sold their vehicles due to the same defects. This pattern suggests a systemic problem with this model, and it is unacceptable that a vehicle this recent is no longer serviceable due to lack of parts and ongoing defects. I have contacted Chrysler support multiple times, but I have received no meaningful resolution. At one point, I was told to use an aftermarket part, which carries no warranty and no guarantee of compatibility. This is not a safe or acceptable option for a manufacturer-supported vehicle. At this point, I am requesting the following: A full investigation into the recurring electrical issues on my vehicle; Chrysler’s support in covering the cost of repairs or offering an alternative solution (e.g., buyback, reimbursement, or replacement assistance); Written clarification on why this part has been discontinued and what Chrysler’s policy is on supporting vehicles in this situat

On 10/27/2020, I financed a Jeep Patriot with 43K miles from Quality Chevrolet. Exactly 6 days later 11/02/2020, while I was on the way home from work in the evening; three sensor lights came on causing the vehicle to jolt / jerk / accelerate and become unsafe to drive. There were cars behind me, I turned on the hazard lights and my car went from 25 MPH to 2 MPH instantly. The lights were ABS, Traction and check engine. I immediately contacted the dealership since I had the Jeep for less than a week. I had to take the risk of driving the car in this condition for 6 miles on a highway back to the dealership, stopping every few minutes to shut off the Jeep and restart to try to reset the sensors, which seemed to work 2 minutes at a time. A drive that would normally take about 15 minutes took over an hour. My Jeep was being paid for weekly and still being serviced at the dealership- On 11/17/2020, I received a call from the dealership that they cleaned out the throttle body as recommended by Jeep and since that was the only sensor active at the time; they told me that no other lights were on so they were driving the Jeep to try to activate them. I was told by Quality Chevrolet that Jeep recommended to clean out the throttle and return to me, if the lights come back on, to go back to the dealer and replace the part. After weeks at Quality Chevrolet, my jeep was returned to me, however 5 days later on 12/07/2020 the same sensors came on in the middle of a highway when I was going about 55 MPH and it was raining I had to find a way to get my vehicle to safety and this caused a lot of anxiety as my kids were in the Jeep this time. I did not get into an accident by a miracle but now I was stranded on the highway. Til this day, Quality Chevrolet nor the 3 other places I have been to have been able to properly diagnose this problem that continues to happen without warning. My jeep will not go over 20 MPH, RPM stays on 2 and all sensors are active.

2PE19014 · Active Head Rest Inadvertent Deployment
Opened Sep 9, 2019 · Closed Feb 25, 2026
Status: closed (inferred from source dates) · Seats; Seats:front Assembly:head Restraint
The Office of Defects Investigation (ODI) opened PE19014 on September 9, 2019, to investigate 128 consumer complaints alleging that the Active Head Rest (AHR) inadvertently deployed without the occurrence of a crash or other rear impact event in model year (MY) 2014 Jeep Grand Cherokee and Dodge Durango vehicles.When ODI opened the investigation, ODI was aware of thirteen alleged injuries.A small number of Early Warning Reports identified driver and/or passenger front seat AHR inadvertent deployments without a rear impact event.Reported safety consequences resulting from the AHR deployments include concussions, headaches, soft tissue injuries, disorientation, nausea, vomiting and/or loss of vehicle control as a result of being surprised and distracted by being struck in the head by the inadvertent AHR deployment. On September 24, 2019, ODI sent an Information Request (IR) letter to Fiat Chrysler Automobiles (FCA).ODI requested certain detailed information from FCA related to the following subject vehicles: MY 2010-2014 Dodge Avenger 200, MY 2010-2014 Dodge Calber, MY 2010-2014 Chrysler Sebring, MY 2013-2015 Ram Tradesman, MY 2012 Ram Van, MY 2010-2019 Dodge Grand Caravan, MY 2010-2016 Chrysler Town and Country, MY 2010-2017 Jeep Compass, MY 2011-2020 Dodge Durango, MY 2011-2020 Jeep Grand Cherokee, MY 2010-2019 Dodge Journey, MY 2010-2012 Jeep Liberty, MY 2010-2011 Jeep Nitro, and MY 2010-2011 Jeep Patriot vehicles.On December 2, 2019, ODI received a response from FCA that included vehicle production data, consumer complaints, field reports, warranty claims, manufacturer actions, production changes, and other data related to the alleged defect from the start of production (2010) through September 24, 2019.On January 27, 2020, ODI received an update to the December 2, 2019, IR response from FCA.On September 22, 2020, ODI requested additional subject vehicle AHR information from FCA.ODI received FCA's response on October 21, 2020.ODI subsequently received an update to FCA's October 21, 2020, response on February 16, 2021.During the investigation, ODI requested updates to certain IR questions on two occasions.FCA provided updates to question #2 on March 5, 2021, and questions #2 and #5 on May 26, 2023. FCA’s IR response data identified approximately 7.5 million subject vehicles (with approximately 15 million AHR assemblies).Due to the large number of vehicles and failure reports, ODI focused its analysis on the FCA vehicle model with the highest failure rate to represent the worst-case scenario.For this purpose, ODI focused on MY 2012-2015 Jeep Grand Cherokee vehicles for its analysis.This population includes 710,890 vehicles that FCA manufactured between August 19, 2011, and August 8, 2015.ODI identified 2,839 alleged AHR failures within this limited population.ODI identified 263 alleged injuries that were caused by AHR failures in MY 2012-2015 Grand Cherokees vehicles.Of these alleged injuries, ODI categorized them as eighty-two (82) soft tissue (neck/whiplash, bruise) injuries, four (4) concussions, fifty-nine (59) headaches, and one hundred eighteen (118) without a specific injury description.Although complainants have alleged injuries, ODI has been unable to obtain evidence to substantiate or validate any injuries where medical treatment was required.Consumer outreach was conducted by ODI, where sixty-three (63) FCA complainants with alleged injuries were contacted.Twelve of the sixty-three FCA consumers responded and were interviewed by ODI.ODI requested medical records, however, only one response was provided. Attorneys representing the responding complainant provided a synopsis that indicated they had experienced prior neck-related injuries dating to the mid-1990s.ODI also contacted one hundred (100) consumers who submitted Vehicle Owner Questionnaires (VOQ) in an attempt to validate alleged injuries. Despite the efforts of ODI, the office has been unsuccessful at obtaining substantive documentation/evidence supporting complaints that allege serious injuries (where pre-existing medical conditions did not already exist). In addition to the low severity of alleged injuries caused by AHR deployments, there have been eleven alleged crashes and two alleged lane departures within the entire subject vehicle population that has been in the field up to sixteen years (with over 8,500 AHR inadvertent deployments).ODI was not able to validate that the alleged crashes were the result of inadvertent head rest deployments, and the crashes were minor in nature. ODI has conducted a thorough investigation of the alleged safety defect and with up to sixteen years of exposure for some vehicles and over 8,500 inadvertent AHR deployments, no serious crashes or injuries could be validated in the sub-population of focus.The lack of serious injuries validated by ODI with such large period of field exposure is consistent with thework done by NHTSA’s Human Injury Research Division and the Biodynamic Research Corporation, which support that an inadvertent AHR deployment is not likely to cause serious injury.In addition to the low risk of injury, FCA released an extended warranty program that covers inadvertent AHR deployment for ten years / unlimited mileage from the vehicle's in-service date. PE19014 is closed with the FCA extended warranty program.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist, and the Agency reserves the right to take additional action if warranted by new circumstances.

EA19001 · Electrical Overstress
Opened Apr 19, 2019 · Closed Sep 19, 2024
Status: closed (inferred from source dates) · Air Bags: Air Bag/restraint Control Module
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.
