What 891 owners told NHTSA about the 2021 Jeep Wrangler 4-door 4xe

Subject: Safety Complaint – 2021 Jeep Wrangler 2.0L Fuel Pump Failure (Loss of power while driving.) I am filing this complaint regarding a 2021 Jeep Wrangler equipped with the 2.0L engine due to what I believe is a significant safety issue involving the fuel pump. The fuel pump has failed, making the vehicle unsafe and/or inoperable. A sudden fuel pump failure can cause the engine to lose power or stall without warning, creating a serious safety hazard, especially when driving at highway speeds, in heavy traffic, or while crossing intersections. A loss of engine power in these situations places both the driver and surrounding motorists at risk of a crash. What is equally concerning is that the replacement fuel pump is currently on a national backorder, with my dealership estimating approximately 45 days or longer before the part will be available. This suggests that many owners may be experiencing the same problem and that replacement parts cannot keep up with demand. As a result, my vehicle is unusable while I wait for a critical safety-related component. This creates a significant financial and personal hardship, including transportation difficulties, missed work, and additional expenses. A safety-related component should not be unavailable for such an extended period if this issue is affecting numerous vehicles. I respectfully request that NHTSA investigate whether fuel pump failures in the 2021 Jeep Wrangler 2.0L represent a widespread safety defect. If a pattern is identified, I urge NHTSA to require Stellantis to issue a recall or other appropriate corrective action to protect vehicle owners and the public. Thank you for your consideration of this complaint.

Vehicle received federal recall 01A service (high pressure fuel pump replacement) at an authorized Chrysler/Jeep dealership on 05/14/2026 at 97,055 miles. I drove the vehicle normally for approximately two weeks (roughly 950 miles), then parked it in my garage awaiting a separate warranty part for the intake manifold. On 07/03/2026, during that warranty repair at the same dealership at approximately 98,000 miles, the dealership’s own technician discovered a diesel fuel leak at the fuel injector supply tube. This line must be disturbed to access and replace the high pressure fuel pump during the recall procedure and is a single-use component. No fuel leak or fuel system issue existed or was documented before the recall service; the vehicle was scanned at the same dealership at intake and the only issue found was an intake manifold valve actuation code unrelated to the fuel system. The leak was confirmed by the dealership and the component is available for inspection; I have requested the removed part be returned to me. Safety risk: the vehicle was driven on public roads for roughly 950 miles while, unknown to me, a fuel line disturbed during recall service was developing a leak. Pressurized diesel leaking in the engine compartment is a fire and roadway hazard. The dealership is charging me for the part and labor rather than covering it under the recall remedy, which provides for replacement of additional fuel system components as necessary free of charge. My concern is an improperly performed or incomplete recall remedy resulting in a fuel leak.

I am filing this safety complaint regarding my 2021 Jeep Wrangler Unlimited Sahara Altitude. The vehicle is experiencing a fuel gauge/fuel reading malfunction. The gauge does not accurately reflect the amount of fuel in the vehicle, which creates a serious safety concern because the vehicle may run out of fuel unexpectedly while being operated on public roads. This defect places me and other drivers at risk, especially if the vehicle stalls in traffic, on a highway, or in an unsafe location. I am requesting that NHTSA review this issue as a potential safety defect.

Since the 68C recall from Jeep, my vehicle has not been functioning properly. The 68C recall was issued because the high-voltage battery cells have a defect that causes them to short-circuit and catch fire. To avoid replacing hundreds of thousands of expensive batteries all at once, Jeep implemented a "fix" via a software flash. The new software "fix" heavily restricts how much power can be drawn from the high-voltage battery to keep it from getting warm. If you push the pedal enough to draw more than roughly 40–50% power—or if the battery temperature hits a strictly lowered threshold—the software abruptly chokes the electric motor and fires up the ICE engine to compensate. Because the electric motor just lost its punch, the computer frantically fires up the gasoline engine to make up the difference. Because there is an inherent delay while the gas engine starts up and matches the transmission speed, it engages with a sudden, frustrating lurch or surge. This is just one of the many problems i have found since jeeps "fix" has been implemented. Basically Jeep elected to reduce the capacity of the battery to avoid costly replacement of the real issue with the battery. This has resulted in a driving safety concern with the surging and hesitation. Also now I can no longer drive exclusively in the electric mode; electric mode is basically non-existent.

I took my car to the dealership to complete the 04b recall. When I got my car back from this recall: 1. The car says driving in electric mode but it uses gas. 2. The car while driving on the highway will hesitate for a split second.. very dangerous. 3. When going on a small hill(example: bridge on turnpike over griffon road) will all of a sudden hesitates and will not get any more power. 4. Multiple times when getting off the turnpike the car slowed to 20mph and would not go any faster for about 15 seconds.. all this while in electric mode.. even more dangerous... I took the jeep back to the dealership, they have had the car for 6 weeks and acknowledge the problems..but Stellantis keeps saying this is normal.. not normal, did not happen before the recall.

There has been an extreme loss of power after the 68c recall making it very unsafe when trying to accelerate. Eventually the car just died and was towed to the dealer.

NHTSA ODI 11743389

When accelerating the vehicle will not go or it will start to move then essentially stop, seconds later it starts moving. There is a delay and it’s extremely dangerous when there is oncoming traffic and/or the drivers behind you don’t realize what is happening. My jeep is a 4xe and this does happen frequently since the last “fix” for the recalls

The primary component involved is the high-voltage charging system, specifically the charging port and connector interface. The vehicle previously experienced a confirmed failure involving a scorched charging port and a melted pin, which required replacement. The same symptoms have since returned, including heat at the charging interface and a burning odor. The vehicle is currently located at an authorized dealership and is available for inspection upon request. This condition presents a safety risk due to the potential for electrical overheating and possible fire hazard. In addition, the vehicle has experienced repeated loss of power while driving, which creates a risk in traffic conditions and could impact driver control and safety. The issue has been previously confirmed by the dealership, which replaced the charging port due to thermal damage. However, upon recurrence of similar symptoms, the dealership has refused to diagnose or service the vehicle, preventing further confirmation at this time. The vehicle has been inspected by an authorized dealership on multiple occasions for related issues, including the prior charging system failure. The manufacturer has not directly inspected the vehicle but has been contacted for assistance. Prior to the charging system failure, symptoms included heat at the charging connector and a burning odor. The vehicle has also exhibited electrical system irregularities and repeated loss of power while driving beginning after recall-related service in or around August 2024.

"The vehicle exhibits a recurring Loss of Motive Power (LMP) during low-speed maneuvers (intersections) and highway speeds (50+ mph). The failure is preceded by erratic instrument cluster behavior (gauge spikes) and results in a total loss of propulsion without prior warning. This defect persists despite the completion of Recall ZB7 and Recall 68C. The dealership has duplicated the failure but refuses further repair, stating the vehicle is 'out of scope' for current remedies, placing the driver at high risk of a collision." Screenshots include: "Written admission from Jeep dealership confirming duplicated loss of motive power and acceleration struggle following a software update. Dealer admits software is 'more sensitive' than previous versions but has no physical way to resolve the safety defect." The manufacturer-authorized repair facility stating they want to release an unsafe vehicle back to me without a remedy. "There is nothing for any of us to do with your vehicle here at Chapman" and tells you to contact Chrysler.

The high-pressure fuel pump (HPFP) failed internally while I was driving at night, causing the vehicle to suddenly stall and shut off completely while my children were in the vehicle. This resulted in an immediate loss of power and created a dangerous situation in traffic. The failure caused metal debris to spread throughout the entire fuel system, and the dealership confirmed that the system requires full replacement. I was quoted approximately $15,000 for repairs. This vehicle previously had a manufacturer recall related to the fuel pump that was completed in 2022 and is now listed as closed. Despite the recall repair, the same failure occurred again. This demonstrates that the recall remedy did not correct the defect. The sudden engine shutdown without warning presents a serious safety hazard, especially at night and with passengers in the vehicle. Its been at the dealer ship for a month.

Vehicle stalled out. Then would not start. Daughter was stuck for 30 minutes until it finally turned over took it into dealership. Was told it’s the fuel pump. My issue is that now. These fuel pumps are back ordered indefinitely found out because all of the fuel pumps are going bad on the jeeps. Now we have a faulty part that the dealership is aware of that you cannot get replaced due to so many of them needing to be replaced, which tells me they know this part is faulty was told they’re not even sure if or when they would be able to get the part now you have all these people driving jeeps that can stall out on the road and get into a terrible accident. My daughter is [XXX] and this is not acceptable. She has a faulty car part and Jeep has no parts to replace this faulty part.

Glendale Dodge (CA) is actively using Federal Fire Risk Recall 68C to fraudulently conceal a separate, critical High-Voltage hardware failure on my 2021 Jeep Wrangler 4xe. Upon intake, my vehicle’s internal VIP diagnostic scan showed an active P0E15 code (Electric Coolant Heater Failure). Per Stellantis Technical Service Bulletins, this code indicates a severe failure requiring a physical hardware replacement to ensure the high-voltage system operates safely. To avoid performing this costly warranty repair, the dealership deliberately falsified the diagnosis on Final Invoice #31349. Under Line C (Customer States Check Engine Light is On), the dealership officially recorded the cause and correction as: 'DUE TO RECALL MODULE UPDATES AND BAD BATTERY.' This is an affirmatively false written diagnosis. A dead 12V battery and a recall software update do not cause, nor do they resolve, a P0E15 High-Voltage Electric Coolant Heater failure. The dealership lied on the legal invoice to scrub the hardware defect from the record. They then applied the 68C software patch as a smokescreen, falsified the 'Date Out' to 12/26/2025 to prematurely close the federal recall ticket, and attempted to return a vehicle that remains mechanically compromised and unsafe. This is intentional warranty fraud masking a high-voltage system failure. Stellantis and its authorized repair facility are refusing to properly remedy the vehicle. The vehicle is currently held at the dealership pending an active fraud investigation by the California Bureau of Automotive Repair (Case #6596-WS4PV6).

I own a 2021 Jeep Wrangler Rubicon 392 with the 6.4L engine (VIN: [XXX] ). The vehicle has a dangerous condition where the engine stalls unexpectedly when the fuel level is approximately 1/4 tank or lower and the vehicle is traveling downhill. When the vehicle is positioned on a decline or downhill slope, the engine suddenly shuts off without warning. This appears to be fuel starvation on decline when the fuel level is below approximately 1/4 tank, resulting in engine stall and loss of power steering and braking assist after stall. This has occurred multiple times and creates a significant risk of crash due to the sudden loss of engine power and reduced steering and braking assistance while the vehicle is in motion. The issue is particularly concerning when descending hills or driving on angled terrain. The vehicle was taken to an authorized dealership (Carvana Jeep San Diego) where technicians determined the likely cause is a defective fuel pump module associated with the Wrangler Rubicon 392 6.4L fuel pump module. However, the dealership informed me the replacement fuel pump module is currently on national backorder from the manufacturer (Stellantis/Jeep). They stated there is no confirmed availability date and that many vehicles may be waiting for the same component. My vehicle has been awaiting repair for approximately four months due to the unavailable fuel pump module. Because the vehicle can stall unexpectedly while traveling downhill, this defect presents an ongoing safety hazard and potential risk of crash. This complaint is being submitted so the issue can be evaluated as a potential safety defect involving fuel delivery failure, fuel pump module malfunction, and engine stall under low fuel conditions in the Jeep Wrangler Rubicon 392.

This is a plug in hybrid vehicle. The (ECH) electric coolant heater is prone to failure. This failure can lead to loss of power and might cause the hybrid battery pack to not regulate its temperature leading to a fire. This is a high failure rate with some saying it has failed more than once. Jeep 4xe Fans on Facebook has been doing some tracking of numbers and shows a 50% failure rate with some failing after being replaced. This failure is not being addressed by Jeep.

My vehicle is subject to an open safety recall (NHTSA Recall 25V-741) involving high-voltage battery separator damage that may cause a vehicle fire when parked or charging. The recall has been active on this vehicle for over four months. The manufacturer and dealers have confirmed the recall applies but have not provided a remedy timeline or parts availability. The vehicle is considered unsafe to park near structures or other vehicles and I have been advised to avoid recharging. No repair has been performed. The condition places occupants and others at risk of fire and prevents safe use of the vehicle. I am reporting this because the manufacturer has failed to remedy this safety recall in a timely manner.

Jeep continues to apply bandaids to the high voltage battery system. The latest recall, 68c, is another software fix that doesnt address the root cause, high voltage battery. after the recall, the car drives horrible when in electric mode - engine kicks on all the time, loss of power until you stomp on the accelerator (which then kicks on engine). NHTSA needs to hold Jeep Stellantis accountable for selling an inferior product and take care of the customers who have supported them for the past 5 years until they stopped selling them! there are 320,000 jeeps impacted, lets fix this!!! I will be scheduling service soon, but you cant expect customers to stop our lives to live at the service center. Jeep really needs to start offering a large scale buyback OR fix the issue which would be to replace the battery with new improved updated one that doesnt become a fire risk every year! Thats where the NHTSA should come in to play - which is "dedicated to saving lives, preventing injuries, and reducing economic costs associated with motor vehicle crashes. It achieves this by setting safety standards, investigating defects, issuing recalls"

Vehicle started and put in reverse. after backing up approximately 15 ft, vehicle put into driver and once accelerator was pressed, vehicle stalled. Tried to restart, engines turned over but stalled again after 1 second. Waited 10 seconds and tried to restart again, stalled again 1 second after turnover. Turned vehicle completely off, opened door, waited 30 seconds, tried starting again and system attempted to stat for 5-10 seconds (push to start ignition so I had no control over how long it tried this), but engine would not turn over. Vehicle also could not be shifted out of park (turned vehicle off and tried to put in “On” position without ever depressing the brake). Vehicle now stuck in driveway and unable to be moved. Acting like an issue with the fuel pump, which is a recall that was announced for some vehicles of this make and model, but NHTSA check shows no open recalls on vehicle. No warning lights or check engine lights came on.

I own a 2021 Jeep Wrangler 4xe – VIN: [XXX] . I previously brought the vehicle in for a recall related to the high-voltage battery. Months later, I received another safety notice instructing me not to charge the vehicle and to park it outdoors away from structures due to fire risk. This indicates the original recall service did not resolve the defect. My vehicle is currently unable to perform its intended function (EV charging/commuting functionality) and may pose a safety hazard when parked. I am requesting NHTSA oversight to ensure FCA/JEEP provides an available remedy and that owners are informed and supported.

Multiple failed recalls to stop vehicle High Voltage battery fires. I've already had the battery pack replaced once and now another recall of a software flash (68c) to test the battery cells separators for damage. So again the issue is still there and this is just another band-aid to catch it before it catches fire. This has been a ongoing issue for over a year and the issue is still not properly corrected. Multiple months of no charging, no parking in garage or near other vehicles/structures just to have another band-aid of a software flash, to stop the fire before it starts doesn't make me feel safe enough to put my family in this vehicle or to still want to charge or park anywhere near other vehicles or structures. This is the same process that "fixed" this issue the last time that obviously isn't a fix at all. The new battery they installed in 07/22/25 is just more of the same junk batteries without a proper fix.

My 2021 Jeep Wrangler 4xe has now been through three separate recalls for the same high-voltage battery fire risk, each time with the same “software flash” remedy instead of a permanent repair. Recall 24V-111 (04B, Feb 2024): Software update to the Battery Management System (BMS) to detect battery faults. Recall 24V-720 (95B, Sept 2024): Reissued for the same defect, again using only a software update. Recall 25V-741 (68C, Oct 2025): A third campaign for the same issue, described once more as a “software flash followed by replacement if needed,” though parts are still unavailable. Each campaign cites potential separator damage inside the battery cells, which can lead to thermal events and fires. Despite multiple “fixes,” Stellantis has never provided an actual hardware remedy or replacement plan. Owners continue to be told to park away from structures and avoid charging their vehicles. More than a year after the first battery recall, the manufacturer still cannot supply a permanent remedy, exceeding the “reasonable time” requirement under federal safety law. I am filing this complaint because repeated software-only updates have not corrected the defect and the vehicle remains at risk of fire. NHTSA oversight is needed to ensure Stellantis provides a true, lasting fix rather than another temporary software patch.

I own a 2021 Jeep Wrangler 4xe Rubicon with approximately 23,000 miles. I recently received notice of Recall 68C (high-voltage battery fire risk). Jeep’s instructions say not to charge the vehicle and to park it outdoors, away from structures, because of potential fire risk. The manufacturer has stated that no repair will be available until at least March 2026, leaving owners unable to safely use or charge their vehicles for months. This recall follows multiple previous recalls and investigations involving fire risk or electrical system failures on the Wrangler 4xe, including earlier campaigns related to the hybrid battery and software updates. The repeated safety issues raise concerns about the overall safety and reliability of this model. My vehicle is otherwise in excellent condition, but I can no longer use it as intended as a plug-in hybrid or safely park it in my garage. Jeep has not offered a timely fix, loaner vehicle, or buyback. I am reporting this because the ongoing risk of fire, coupled with repeated recalls and long repair delays, represents a serious safety hazard that deserves immediate NHTSA attention.

The vehicle has multiple critical, uncorrected safety defects: Loss of Motive Power (RQ24012), Engine Contamination (CSN 78C), and Battery Fire Risk (Recall 68C). Incident Details (R/O [XXX], [XXX]): My 2021 Jeep Wrangler 4xe experienced a sudden and complete Loss of Motive Power while operating. The customer concern noted on the Repair Order states the vehicle "seems to loose power while driving above 30MPH... and feel like it was going to turn off." This failure rendered the vehicle inoperable and created an extreme safety hazard on a major roadway [XXX] ), forcing me to coast to safety. Component Failure and Safety Risk: The failed components are the Engine (2.0L Turbo), Hybrid Propulsion System, and Electric Coolant Heater (ECH). The dealer's repair (R/O [XXX]) confirmed system instability by replacing the ECH. This loss of power is directly linked to the manufacturer's known defect (CSN 78C), where sand contamination in the engine can cause catastrophic failure and unrecoverable loss of propulsion. This mechanical defect is the root cause of the safety risk and is currently under NHTSA investigation (RQ24012). Additionally, the vehicle is subject to Recall 68C (Battery Fire Risk), preventing safe use of the PHEV system and forcing me to park away from structures. The combination of these uncorrected defects puts both my safety and the safety of others at risk. Warning Lamps: A 'Service Hybrid System' light or similar warning message appeared at the time of the incident. The problem has been confirmed by the dealer (Price Chrysler Dodge Jeep Ram) and is documented in Repair Order [XXX]. The component is available for inspection upon request.

I own a 2021 Jeep Wrangler 4xe Unlimited, which has undergone three manufacturer recalls and two separate service (one handle during a recall visit) visits due to charging failures. The recalls were related to defrost system malfunctions, sudden loss of motor power, and high-voltage battery concerns. Each of these issues was addressed solely through **dealer-installed software updates**—updates that could not be completed over the air. These recalls and service visits highlight a troubling pattern: the vehicle’s core systems—including the BPCM, IDCM, PIM, TCM, and HCP—are deeply interconnected and dependent on one another. So far, my vehicle has required a total of **10 software updates**, with some systems needing multiple revisions. Most recently, Jeep addressed a “not charging” problem by once again performing a software update—this time affecting **five of the seven systems previously updated during recalls**. Despite the problem originating from their software architecture, Jeep charged me **$200 for the update**, even though it stemmed from an issue caused by their failed over-the-air deployment strategy. These recurring failures are not isolated incidents—they represent a systemic flaw within the vehicle’s hybrid management and safety systems. Relying on repeated software patches to resolve critical defects is not only unsustainable—it’s creating **unsafe driving conditions** and placing an unfair burden on the owner.

The gas indicator indicated that I had 35 miles left to empty, it showed an eighth of a tank still available but completely shut down on me on the freeway. The car completely shut down to the point that I was not even able to pop it in neutral to help roll it to a safer place further off the highway. Fine, the gas gauge is wrong, but not being able to put it in neutral for my own safety and the safety of others is unacceptable.

The jeep was taken to the dealership under a software battery recall and the software was updated. One week later while driving at approximately 55mph, there was a sudden jerk in the propulsion system. the car shifted abruptly from electric to gas motor and the electric mode was unavailable. The vehicle jerked and hesitated at every acceleration and deceleration causing unsafe operating conditions . The check engine light was on I returned it to the dealer immediately and was told that the high voltage hybrid battery was bad. I'm pretty convinced from my and other experiences that the software up date was not a remedy to previous incidents reported to you. It was a software patch that determined if the battery was bad.
