Dear National Highway Traffic Safety Administration, I'm writing to report a critical safety concern regarding the 2018 Jeep Grand Cherokee's water pump design. As an owner, I've experienced persistent coolant leaks, which I've found is a widespread issue affecting many others. This problem stems from a fundamental design flaw in the water pump, not typical wear and tear. The issue centers on a small "freeze plug" that leaks when the engine reaches operating temperature. This plug serves no apparent purpose and causes premature failures and coolant leaks across numerous vehicles. Key points: The leak occurs consistently when the engine is hot, indicating a design-related problem. This issue potentially leads to engine overheating and severe damage. It affects many vehicles, particularly those with the 3.6L V6 engine. Extensive research on online forums confirms this is a common problem. A YouTube video [XXX] ) provides insight into the issue. The creator states: "Upon digging into this a bit deeper, I don't believe it's the 'weep hole'. It's actually like a small 'freeze plug' that leaks on these pumps. If you look through the pulley at the opposite side of the aluminum freeze plug that leaks, you will see the weep hole. This 'freeze plug' that leaks serves no purpose as far as I see it. It's just like they slapped this plug in the front of the pump… and it leaks when it gets hot." Given this evidence of a design flaw and its widespread impact, I urge NHTSA to: Investigate the water pump design of the 2018 Jeep Grand Cherokee and similar models. Assess the safety implications, including the risk of engine overheating and potential vehicle failures. Consider whether a recall or other corrective action is necessary. The fact that this is a design issue rather than wear-and-tear underscores its urgency. All vehicles with this water pump design are potentially at risk, regardless of mileage or maintenance history. Thank you INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Jeep uses a transmission manufactured by ZF. Jeep claims the transmission is "filled for life" and does not require any maintenance, and never requires the oil to be changed. ZF recommends the oil be changed every 50-75,000 miles. Many other car manufacturers that utilize ZF transmissions recommend that same interval. In fact, if you push Jeep to change your transmission oil, they suggest it will void your warranty. Preventative maintenance in the form of a transmission fluid change is necessary for the health and longevity of the vehicle. Jeep is negligent in this matter. When your transmission fails, you are thrust into "limp" mode, capping your speed at 15-20 mph. This occurred to me on the highway. I narrowly avoided being rear ended in traffic traveling 65+ mph. My car has been babied, all factory recommended services have been done in a timely manner, I was not having any issues with the car at the time, and there were no symptoms, warning lights, etc at the time.

3EA23001 · High Pressure Fuel Pump Failure
Opened Mar 17, 2023 · No close date supplied
Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump
The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337

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).

PE19014 · 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.
