general problems of the 2024 Jeep Wrangler - part 1

2024 Jeep Wrangler 4xe models. Sudden loss of power while driving up hill in the electric mode. It would not go over 59 miles per hour and then it switched over to hybrid all on its own. This happened a few times and I could not go fast enough on the freeway. The next week the check engine light was on along with, engine warning light: service battery charging system and it would not start. I have a 2024 Jeep Wrangler 4xe sahara. All recalls are up to date. My Jeep suddenly lost acceleration while I was driving. It happened more than once, including a frightening situation when my vehicle rapidly slowed from approximately 65-59-45. My Jeep was subsequently towed to the dealership.

After a cold start (sitting for a few hours or overnight) if I were to give the vehicle some gas, 15% pressure on the petal, the car bucks violently shifting from 1st to 2nd to the extent of 'chirping' the tires. This happens about 50% of all starts, the severity varies from slight (like a small bump in the road) to violent (chirping the tires \ breaking suddenly) it's been reported several times to the dealer but they cannot replicate the issue.

Was difficult to start and check engine was immediately on after I got it started. Was running sluggish and went into turtle mode while driving it to the dealership.

This is a 2024 Jeep rubiconx with 10. 5k miles. I was running 60mph on a state highway on electric mode. I didn’t see the battery was nearing 50%… sure enough Jeep lost power at 50% charge even though I was trying to floor it to keep it moving. The ice kicked in a few seconds later. There was a car right behind me and understandably started honking his horn thereafter. Not even sure if my tail lights turned on when it lost power- I’m assuming not because my foot wasn’t on the brakes. Next morning the Jeep is dead. Dealership confirmed hv battery replacement. I’m just not sure how these are still allowed on the road. Specially with what 3 or 4 recalls on the same batteries with which Jeep’s resolution is simply a software update to detect any bad battery? even with the 4th recall on the same issue, there are still reports of vehicles catching up on fire while parked. Not sure how you can keep letting them get away with this. Now Jeep has been throttling battery and electric performance without letting the owners know of the changes- this last recall (68c) they installed the 50% threshold mentioned above where the battery will just stop providing power and make the engine take over after some delay. This experience is not unique to me- it has been reported by several others in the largest Jeep 4xe forum. Endangering peoples lives by killing battery power abruptly in the middle of the road to save stellantis/Jeep money from actually putting a fix on the issue is just another Ford pinto moment. After our batteries die, they get replaced by…. . The same exact faulty battery so that we can go through the same experiences over again. Jeep hasn’t addressed the root cause of the issue- bad battery design, and here we still are with hundreds of thousands of Jeeps on the road that may abruptly die in the middle of the road or catch fire on the lot. We can do better than this.

I left my home for work on xxx. I noticed a lack of propulsion upon stepping on the gas & air conditioning blowing warm air. At a stoplight ([xxx] and [xxx] in [xxx]), I attempted to restart the vehicle in hopes that a reset may fix any issues. What I found was that my vehicle would not restart and I could not remove it from park in a busy intersection. After 30 minutes of trying, I was able to get it to turn on and move to the burger king parking lot. A tow truck arrived and took me to the [xxx] valley chysler Dodge Jeep ram dealer. They told me it would take until Tuesday xxx to look at it. They could not offer me a loaner nor a rental vehicle. They called on xxx and said it was a battery defect and may take weeks to repair. To date, my vehicle with 27,000 miles have been in for four separate recalls, citing lack of propulsion, risk of battery fire. Zero accidents. I no longer feel safe driving the vehicle after recalls: "the 2. 0 engine may be contaminated with sand from the casting process . . . Leading to catastrophic engine failure. " "firmware software. . . May cause loss of drive power which can cause a vehicle crash. " "the high voltage battery may become damaged during normal vehicle operation . . . Advising owners to park away from structures or other vehicles" "electric hydraulic power steering pump may have electrical issue . . . May lead to a fire. " the manufacturer and dealer are offering minimal insight or restitution for my experience or safety. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

2024 Jeep 4xe Wrangler rubicon, 3 recalls, 1st ev battery, potential fire hazard, 2nd sand in the engine, potential fire hazard, 3rd wiring harness for steering unit, potential fire hazard, all of them can cause a fire with it being parked and not even plugged in for charging. Fca sent out the recall notices, and later said they had remedies, the problem is the remedies aren't remedies at all. I was at my dealership 2 days ago talking to my service writer, and he told me that another customer with the same vehicle passed the so called remedy for sand in the engine, a few days later his engine light came on, and now the dealership is replacing his engine, with that being said doesn't that mean that even with a passed so called remedy, it could still be a fire hazard. I have had all the recalls done at my dealership, but I don't feel that they are being honest about any of these remedies actually working, and that everytime I get in the vehicle or park it I'm afraid that it could still catch fire. I have a vehicle that has been taken off the market by the manufacturer, and has told the dealerships not to sell them, I have tried to get some reimbursement, but have had no luck, am hiring an attorney to try to get something done.

On xxx I was driving to work at 0600 engine started to lose power (after a recall for same complaint @ 2 weeks prior) and fail, I was able to limp it to the friendly Jeep dealer in [xxx]. They have had my car for 31 days with no resolution and without providing a loaner or rental. I'm paying for a car I don't have and a rental stellantis should be paying for. There is no plan for repair or timing of new engine replacement. I filed formal notice of dissatisfaction and intent to pursue all available legal remedies. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

After completing the 68c recall, one week later, my Wrangler got the red turtle message and the check engine light came on. I lost power and the fan went on full power and sounded like a jet engine. Lost power on the highway. It has been at the dealer for 4. 5 weeks and still has not been looked at to diagnose. No loaner. No rental. Nothing. It is unsafe to drive so it has to be left at the dealer.

On xxx my engine light came on and the engine overheated excessively. I pulled over immediately. I towed the vehicle to the Jeep dealer ([xxx]) on xxx. Service took the vehicle in for service to review the issues and refused to ground my lease that is due on xxx. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Following the completion of the 68c recall update on 4/17/26 my 2024 Jeep 4xe experiences a severe loss of acceleration and throttle lag at highway speeds (over 50 mph) when in electric mode. When attempting to pass vehicles (and sometimes when in the oncoming traffic lane), or when just trying to maintain speed in traffic, the drivetrain abruptly throttles power; causing the vehicle to bog down and hesitate. There is no ability to accelerate and care slows. The gas pedal is essentially useless. The gas engine then performs a panic start, causing the vehicle to lurch forward at highway speeds. It has created and dangerous driving condition when passing, merging or just trying to keep pace the traffic around me. There is no way to know exactly when it will happen, so the unpredictability makes it even more dangerous. I understand this is an issue with many Jeep 4xe since the 68c recall update. It has happened to me 4 times now, the most recent was today. This is unacceptable.

Intermittent delayed/loss of acceleration when accelerator is depressed, along with abnormal switching between electric and gasoline propulsion. Symptoms began after recall 68c was performed. I was on all electric at the time going 40 mph when compressing the accelerated did not work and the car seemed to slow for a few seconds before it engaged. I have roughly 15,500 miles on the Jeep and got the 68c done last fall.

Vehicle engine light comes on and says loss of power restart engine. Dealer found no codes and no repairs were made. This is the second occurrence.

I was on the freeway and the vehicle loss power and not allowing me to speed the vehicle up. I was stuck in the middle of traffic and I was concern for my children safety.

I am requesting NHTSA investigate the handling of safety recall 78c on my Jeep Wrangler 4xe. My vehicle has entered a dangerous highway limp mode multiple times, including at approximately 75 mph, with sudden loss of power and an acc! warning. This is especially dangerous on California highways and steep grades where losing propulsion can make it impossible to maintain traffic speed or safely reach a shoulder. The acc! warning has appeared three times. On one occurrence, while the warning was active, o’reilly auto parts scanned the Jeep and documented pending code p2338, cylinder 3 knock control threshold. I have the printout showing my VIN and mileage. The problem is that the warning/code clears after the ignition is shut off. When the condition happened on a Saturday, the Jeep service department was closed. Dealership sales staff refused to scan it and said only a technician could use a scanner. Even during business hours, the dealer says only a technician can scan it, but technicians may not be available for days. It is impossible to leave the vehicle running indefinitely waiting for someone to scan it. The santa maria Jeep dealer has now driven the vehicle twice and says that because the warning did not reappear during those short drives, they cannot confirm the condition. These events have occurred days apart, so two short test drives do not rule out an intermittent engine defect. I had the Jeep towed through Jeep roadside assistance because I consider it unsafe to drive. Jeep cares has assigned me three different case managers in three days. They state they cannot require the dealer to examine deeper stored diagnostic data because they are third-party contractors. I have photos of the acc! warning, the p2338 diagnostic report, VIN, mileage, tow documentation, and repeated loss-of-propulsion history. Jeep cares and the dealership won't look deeper or longer even with the proof it was there.

While driving my vehicle, I have noticed a significant decrease in power and a corresponding slowdown, particularly in traffic conditions. This has resulted in a near-miss collision with another vehicle in the rear. Furthermore, attempting to accelerate the vehicle has proven futile. Ps. The dealer where I brought the vehicle is kinda giving me a hard time & I fear for my family safety. Honestly I dont feel like the dealer was being completly honest.

Engine temperature went up while driving. The warning light came on and I immediately pulled to the side of the road. After 6 minutes on the side of the road the engine started to smoke and then caught fire.

The Wrangler 4xe after the latest recall has had issues with power, switching from driving with all electric to driving with the engine running. Have had several instances of very laggy pedal response (even at highway speeds) which could cause a safety issue or accident.

My Jeep after the 68c recall work was performed to lessen the chances of a fire caused by the hybrid battery now under performs compared to before the recall. I get much less that the advertised ev / battery only miles. Also, the vehicle hesitates while trying to transition between battery only and hybrid modes. My only recorse is to not use the battery only mode because it is a safety concern.

Since the completion of the 68c recall, my Jeep has a concerning issue: when driving in “electric” mode for about 15-20 minutes, the available power starts to decline. Despite pressing on the accelerator it continues to decline for about 10-15 seconds. Then the screen displays “electric mode temporarily unavailable”, the ice starts and engages (with no warmup) and the Jeep switches to “hybrid” mode. This all happens despite there being a 40%+ charge remaining on the battery and ambient temperature being less than 70 degrees f. I believe the 10-15 seconds of reduced power poses a significant safety risk in a situation such as passing a vehicle or pulling out in traffic.

My 2024 Jeep Wrangler 4xe was brought to an authorized Jeep dealership on July 25, 2026 for recall/warranty-related issues. The vehicle currently has approximately 17,000 miles and has remained continuously in the dealership's possession since July 25. As of September 21, 2026, the vehicle has been unavailable to me for approximately 58 days and has still not been repaired or returned. The dealership has verbally informed me that the vehicle requires replacement of both the engine and the high-voltage battery. However, I have not been provided the specific recall campaign numbers in writing. According to the dealership, the repair has been substantially delayed while waiting for the necessary parts from Jeep/fca. The vehicle remains at the authorized dealership and is available for inspection. I am concerned that safety-related defects serious enough to require replacement of both the engine and high-voltage battery have left this vehicle unusable for nearly three months, with no completed repair and no firm return date. I am reporting this because Jeep/fca has been unable to complete the required recall-related repairs within a reasonable period. The vehicle has been inspected and diagnosed by an authorized Jeep dealership, which continues to retain possession of it. I am requesting that NHTSA review this extended repair delay and Jeep/fca's ability to provide the required safety-recall remedies and replacement parts in a timely manner.

I was driving my 2024 Jeep Wrangler 4xe on a public road when the vehicle experienced a sudden loss of propulsion. Before driving, the check engine light was illuminated, and the air conditioner was blowing hot air instead of cold. Shortly after pulling onto the roadway and while approaching a stoplight, the vehicle lost power while it was still in motion and became inoperable, requiring it to be towed to the dealership. The dashboard displayed “service hybrid electric vehicle system. ” the vehicle has fewer than 20,000 miles. I believe this is a serious safety concern because the loss of propulsion occurred while driving, leaving me stranded in traffic. I no longer feel confident in the safety and reliability of this vehicle.

One two occasions on the freeway the display will state "service engine see dealer" and then the car goes into a limp mode and essentially shuts down. Both times we've had to quickly get to the emergency lane, wait for several minutes then turn the vehicle back on. We've taken the vehicle to the dealer and they stated that they diagnosed it and tried to recreate the issue but cannot reproduce it so they say there is nothing to fix.

What component or system failed or malfunctioned, and is it available for inspection upon request?multiple components across four separate manufacturer safety recalls: (1) the high-voltage battery (recall 68c), currently being replaced by the dealer; (2) the hybrid control processor / drive system (recall a7c); (3) the electric hydraulic power steering pump (recall 21d); and (4) the 2. 0l engine (recall 78c, status disputed — see below). The vehicle is currently at the authorized dealer and is available for inspection there. How was your safety or the safety of others put at risk?recalls 68c and 21d are both manufacturer-designated fire risks; 21d specifically carries an "urgent: fire risk when parked" designation in NHTSA's own database. Recall a7c describes a loss of drive power without warning while driving, which the manufacturer states may cause a vehicle crash. I experienced a stalling event with the drive indicator blinking on 10/17/2025 (10,553 miles); unknown whether this was directly caused by the a7c defect, but the symptoms match the recall's description. Has the problem been reproduced or confirmed by a dealer or independent service center?the 68c battery failure has been confirmed by the dealer, who is currently performing a full battery replacement. Unknown whether the 10/17/2025 stalling event was ever formally diagnosed as connected to recall a7c; the dealer's repair order for that visit does not reference a7c or a root cause. Unknown whether recall 78c's applicability to my vehicle has been confirmed or denied by the dealer — see discrepancy described below. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others?the vehicle has been inspected and serviced multiple times by the manufacturer's authorized dealer. Unknown whether any fca/stellantis field engineer or investigator has separately inspected it. No police involvement; no c.

My 2024 Wrangler 4xe has 27,000 miles on it. On Friday, 7/10/2026 around 7:00 in the morning the check engine light came on. I immediately called the dealer to set up an appointment and they could not get me in until 7/15/2026. At about 9:30am that day when I was pulling a small trailer the battery light also came as I was driving on the interstate. As soon as I exited and slowed down, the car lost all power. It would not start or move. I was stranded on the exit ramp in the turn lane, with a trailer, unable to get to the shoulder. There was quite a bit of traffic around me. I was able to have it towed to the dealer. I had to safely get out of the vehicle and direct traffic around the vehicle. Today, 7/15/2026, the dealer ran the diagnostics and determined that the hybrid battery has failed and needs to be replaced. The car currently has 27,000 miles on it and this is now the second hybrid battery replacement and the third time the Jeep has stranded me and has required a tow to the dealer. It is unreliable and unsafe as it becomes immobile and loses power on the roadway.

The contact owns a 2024 Jeep Wrangler. The contact stated that while driving 15 mph the vehicle experienced a complete loss of automotive power, the steering wheel locked up, and all of the warning lights were illuminated. The vehicle came to a complete stop and was restarted. The contact continued to drive the vehicle was taken to a local dealer where it was diagnosed and the contact was advised that no failure was found. The contact continued to drive the vehicle, and the failure reoccurred while driving at 75 mph, the vehicle experienced a complete loss of automotive power, the steering wheel locked up, all of the warning lights were illuminated, and the following the message appeared on the instrument panel "until you reach a desired location you may not be able to shift until serviced, do not take the vehicle out of gear until you are in a safe location". The vehicle was towed back to the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 17,592.

When I am driving I will lose power and not be able to drive while I am in the middle of a road driving. And I have to turn my car completely off to let it start back up. The dealership doesn’t not seem to have any more suggestions or recommendations. I feel unsafe driving this vehicle. This keeps happening.

After performing the 68c recall vehicle no longer drives the way it was designed. When in hybrid mode pushing the accelerator to the floor results in a 2-6 second delay waiting for the gas motor to kick in and then it slams the power into the car. This car is extremely unsafe and impossible to merge into the highway correctly now. Car does not show any warnings and dealer claims this is normal operation.

Was traveling approximately 55 mph down the highway for 15 min in electric mode. Moved to the shoulder and stopped quickly using regenerative braking for an oncoming emergency vehicle. I got back on the highway and I suddenly lost almost all pedal response and it would not accelerate. I kept pushing the accelerator pedal harder and harder. That's when the ice kicked on and there was a sudden violent lurch forward and the engine was screaming at over 5000 rpm. There were cars approaching behind me and they had to suddenly stop and they honked horns and avoid hitting me. This sudden throttling of the battery/electric and very erratic switch over to ice is dangerous.

Since having the battery recall done in January, my Jeep is a completely different car. In electric mode, it can no longer go up hills without losing significant power to the point where it slows down a lot. I have to manually change it to hybrid mode so that I don't get rear ended. It will no longer quickly and effectively change by itself like it did before the software update. It has also been having issues with power when going around turns or accelerating from a stopped position. In order to go more than 20-25 mph, I have to floor the pedal after completing the turn. This creates a problem when trying to merge into traffic and/or turning into the far lane and crossing traffic to do so. This puts myself and others in danger when trying to merge/cross. I have taken it back to the dealer twice now for power issues and this past time (June 2026), even though the techs could tell there was an issue, Jeep is saying that it's "normal" functioning after the recall update. There is no specific date for this incident, as it happens everytime I drive it. I can no longer trust this car to keep me safe in normal driving conditions.

Vehicle: 2024 Jeep Wrangler 4xe (VIN: [xxx]) complaint description: my vehicle is currently under active NHTSA recalls 25v-766 and 26v-363. Following the 25v-766 software flash designed to detect internal engine bearing failure, the vehicle has experienced a sudden, unrecoverable loss of propulsion (limp mode) on the highway at 60 mph on three to four separate occasions. This has nearly resulted in high-speed rear-end collisions, making the vehicle incredibly dangerous for my family. The vehicle is currently grounded at criswell Jeep in maryland. Despite the vehicle experiencing the exact catastrophic failure outlined in 25v-766, stellantis corporate and the local dealership are refusing to authorize the mandated engine block replacement. The dealership claims their local technicians cannot physically replicate the failure and do not know how to extract the historical freeze-frame data from the vehicle's computer. Instead of dispatching a stellantis field technical specialist to pull the internal uconnect logs—which Jeep cares corporate admitted on a recorded line is the required next step if the local tech cannot duplicate the issue—the dealership has put over 150+ unnecessary test-drive miles on the vehicle and consumed half a tank of gas trying to blindly trigger the failure. Conducting 150 miles of highway test driving on a vehicle with a documented history of suddenly losing propulsion while it simultaneously has an active, unpatched fire risk (26v-363 "park outside" advisory) is a severe safety liability. Furthermore, Jeep cares explicitly refused to reimburse me for the gas and mileage, stating this excessive driving is just part of their diagnosis and quality control. The manufacturer is negligently failing to execute a federal safety recall by refusing to utilize proper engineering diagnostic tools, leaving information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

This is apparently an ongoing problem with all Jeep 4xe's that have passed the 68c recall. The vehicle will no longer operate in "electric" mode in normal driving conditions, this is our second Wrangler 4xe and we have a total in excess of 50k miles of typical driving in "electric" mode. The vehicle will no longer function safely in "electric" mode as it did prior to the recall, it now fails to accelerate for minor hills and slows down to the point of causing following vehicles to come dangerously close to the rear of the vehicle. After a long delay with the pedal now to the floor and the vehicle slowing further as it's trying to go up an incline the ice (gas engine) violently starts and lurches forward in an unnatural manner. The response by stellantis is that this is "normal" operation of the vehicle. I can 100% tell you this is not normal as neither of our 4xe's operated in this manner prior to the recall. I can only imagine what would happen if we attempted to merge into traffic or try to cross an intersection and this "normal" operation happened.

While driving in ev mode my Wrangler 4xe starts to limit power when the battery falls below 50%. The dash display which shows power output clearly starts to limit around 75%, then 50% once the battery hits 40-45% and then even lower as the battery depletes. This makes the car barely powerful enough to hold 50mph and it cannot even climb a hill and hold speed. Then the engine abruptly kicks on in the high 30% battery soc and ev mode is locked out until you charge it or park, turn it off and let it cool off. This is after the latest battery recall that Jeep performed. They seem to be limiting the battery output at lower soc to protect the battery but this means I am no longer able to operate the car I purchased in the way it was designed to originally, the way it was marketed, or even safely on a main road with moderate speeds without the engine kicking on. It is also limiting overall power which means I'm not getting the advertised hp and torque ratings. Jeep needs to do a real fix for the battery issue and not just a software band-aid.

1. The vehicle has experienced multiple safety-related defects and is available for inspection upon request: the instrument cluster panel was subject to safety recall and required service. The radio system suffered an internal malfunction. The electric hydraulic power steering system was subject to a safety recall issued on June 11, 2026 and no remedy is currently available from the manufacturer. 2. The instrument cluster defect could prevent the driver from viewing critical safety information, like speed, odometer, and warning indicators. The electric hydraulic power steering defect poses an even greater risk, as a loss or reduction of steering assist could impair vehicle control and increase the likelihood of a crash. Additionally, the recalled steering system may overheat and cause a fire, whether the vehicle is being driven or the engine is off, creating an immediate life-threatening hazard to occupants, nearby persons, vehicles, and property. This is especially concerning as a texas resident driving in the summer months with extreme temperatures. 3. The instrument cluster issue was addressed through recall service performed by an authorized Jeep dealership. The radio/internal failure was reported to the dealership, which acknowledged the malfunction. The power steering issue has also been recognized by the manufacturer through the issuance of a safety recall on 6/11/2026. 4. The vehicle has been inspected and serviced by authorized Jeep dealerships in connection with the instrument cluster recall and the reported radio malfunction. Additionally, the vehicle underwent multiple routine service inspections before the power steering recall was issued, and no steering-system defects or safety concerns were identified or disclosed. 5. No warnings or messages appeared before the failures. Radio failure caused infotainment screen to go blank while instrument cluster and power steering issues were identified by manufacturer recalls instead of vehicle warnings.

While driving on the highway, the vehicle suddenly lost power and would not accelerate beyond approximately 60 mph. This created a safety risk because I could not maintain normal highway traffic speed. I brought the vehicle to an authorized dealership, where a recall repair was performed. However, the same loss-of-power issue occurred again. After further inspection, the dealership informed me that the vehicle is subject to safety recall 78c and requires a complete engine replacement. I am not a technician and cannot determine the exact cause of the failure; I have relied on the dealership and stellantis for diagnosis and repair. The dealership confirmed that the replacement engine is on backorder and the repair cannot be completed. My vehicle has been at the dealership since June 2, 2026, and has been unavailable for nearly two months. The vehicle is available for inspection upon request. Neither the dealership nor stellantis has provided an estimated date for parts availability or repair completion. The timeline is unknown. The recall and engine replacement requirement were confirmed by the authorized dealership. The vehicle has not been inspected by police or insurance representatives. Manufacturer inspection is unknown. I do not recall any warning lamps or messages before the power loss occurred. I continue to make monthly lease payments for a vehicle I cannot use. No loaner vehicle was provided. Stellantis offers rental reimbursement of up to $50 per day, but this does not cover actual rental costs. Even the least expensive rentals in my area exceed $50 per day, requiring me to pay additional expenses out of pocket. This is the second time a manufacturer recall has caused an extended loss of vehicle use. A previous recall kept my vehicle unavailable for more than one month. My lease expires in February 2027, but I continue paying while the vehicle remains unusable. I requested a buyback due to the lack of a repair timeline, but stellantis denied my request.

I own a 2024 Jeep Wrangler 4xe high altitude (VIN: [xxx]) with three open safety recalls, two of which involve fire hazards: NHTSA id 25v741000 – high voltage battery may fail and cause fire (parts available) NHTSA id 25v766000 – engine failure may cause fire or loss of drive power (parts not available) 2. 0l phev engine recall (parts not available) I have been trying to schedule a recall repair appointment for several days. The dealership failed to confirm parts availability, gave no clear answers, and ultimately hung up on me during our conversation. Despite the NHTSA website confirming that parts for recall 25v741000 are available, the dealership was unable to schedule an appointment and provided no solution. I am being forced to drive a vehicle with an active fire hazard while the dealership refuses to take responsibility or provide timely service. This is a serious safety concern and I am requesting immediate action. The dealership has shown complete disregard for customer safety and has failed to fulfill its obligation to complete open safety recalls in a timely manner.
