Engine And Engine Cooling Problems of Jeep Wrangler - part 1

The check engine light was on and it said to service the battery charging components. When driving in hybrid mode it doesn’t switch to use the battery. When I was trying to pull off after stopping, the Jeep hesitated and would not move and then all of a sudden jerked and took off almost making me crash and people crash into me.

Vehicle shuts down and looses all power and battery controls without warning. My 18 y/o daughter was driving the Jeep when this happened. Was unable to get vehicle into n for over an hour. Fuses and relays inside the under hood fuse block were extremely hot. After finally getting it into n, we removed from the travel lanes of the 4 lane highway. I had Jeep towed to house and waiting to hear back from dealer as to when I can have it towed in.

While driving my 2023 Jeep Wrangler willys 4xe at approximately 40 mph in electric mode with approximately 26% battery charge remaining, the vehicle suddenly and unexpectedly lost propulsion. The green indicator on the instrument cluster that normally shows electric operation changed to yellow. Immediately afterward, the Jeep abruptly lost power and began rapidly decelerating. I was not applying the brakes. The dashboard displayed "service charging system" along with a red warning symbol resembling a charging cord. I was able to get the vehicle off the roadway and into a parking lot. The Jeep then came to a stop. The vehicle remained powered on and the dashboard remained illuminated, but pressing the accelerator produced no response. The Jeep would not move. I turned the vehicle completely off and waited several minutes. When I restarted it, the Jeep started and operated normally again. The Jeep spent approximately three months at an authorized Jeep dealership for multiple electrical/charging system problems and diagnostic trouble codes. During that time, the 12-volt battery was replaced and the integrated charging dual module (icdm) was replaced. The Jeep operated normally for approximately three months following those repairs before this incident occurred. This was an extremely serious safety event. The vehicle unexpectedly lost propulsion while actively traveling on a public roadway. If this had occurred at highway speeds, while merging, crossing traffic, or in heavy traffic, I may not have been able to safely get the vehicle off the roadway. I am particularly concerned because the malfunction disappeared after shutting the vehicle off and restarting it, making the failure intermittent and unpredictable. I am requesting that NHTSA investigate this sudden loss-of-propulsion incident and determine whether it is related to other reported loss-of-motive-power problems involving Jeep Wrangler 4xe vehicles. The photograph included is not my Jeep but shows what happened.

I’ve had an ongoing issue with my car since earlier this year, 2026, and the code says “electric coolant heater” and I have a solid check engine light. They replaced the coolant heater a few months ago and now it’s doing the same thing again. There’s also another recall for the power steering and I’ve recently started to notice that when I start my car (which I normally will sit there for a few minutes before I drive to let everything “wake up”) there is a delay in the steering ability. My steering wheel will remain stiff unless I jerk the wheel to “wake it up” in a sense. This just started happening this week. The dealership that I got this thing at is being no help whatsoever and I’m getting tired of this!!! they don’t have a loaner car available to me so they’ve been telling me to wait to make a service appointment until they have a car available but I cannot wait on this issue any longer. Matter of fact, this is absolutely ridiculous considering how much I pay for this thing every month and how lack of help the dealership has been!!!! I need a solution for this now.

My complaint with Jeep/stellantis goes far beyond dissatisfaction with a buyback amount. My family leased a new 2025 Jeep Wrangler expecting a safe vehicle, and instead we have been placed in a worse position after dealing with serious recall and safety concerns. Fca has agreed to repurchase our vehicle, yet the process requires us to continue maintaining and driving a vehicle we no longer feel safe using while waiting weeks for the repurchase to be completed. A potential vehicle-fire condition is not a cosmetic defect or minor inconvenience—it is a legitimate safety concern involving the driver, passengers, surrounding vehicles, homes, and property. My three primary concerns are: **(1) safety:** Jeep has vehicles in customers' possession subject to serious safety recalls involving potential fire hazards, yet customers may still be left waiting for repairs or resolution. **(2) remedy:** even after fca agreed to repurchase our Wrangler, the proposed financial resolution leaves us in a worse financial position and without sufficient funds to reasonably transition into a replacement vehicle. We were offered substantial compensation to keep the vehicle, but keeping a vehicle we are concerned could present a fire risk is not a reasonable solution for our family. **(3) process:** once a manufacturer acknowledges a serious safety issue and agrees to repurchase a vehicle, there should be an expedited process to remove that vehicle from the customer and provide a fair resolution—not weeks of additional payments, paperwork, uncertainty, and continued possession of the affected vehicle. What concerns me most is that this is bigger than our individual case. Safety recalls involving potential vehicle fires can have serious consequences, and manufacturers should treat them accordingly. Customers should not have to choose between continuing to drive a vehicle they do not feel safe in or accepting a resolution that puts them in a worse financial position. Jeep/stellantis needs to.

From a stop sign vehicle would only accelerate to 4 mph and then completely lost forward propulsion, forcing a tow to the dealership.

On [xxx], my 2019 Jeep Wrangler unlimited rubicon (2. 0l turbo) caught fire in the engine compartment while driving, at approximately 101,437 miles. The fire started near the turbocharger and heat shield area. There were no injuries, but the vehicle was moving on a public road with four occupants, including two young children in car seats in the rear, when the fire started. The vehicle had been returned to me four days earlier, after approximately 2. 5 months at preferred Chrysler Dodge Jeep of muskegon, mi for a timing chain replacement. After the fire, I found that the coolant reservoir hose had come off its fitting, and the hose barb appears to have been broken and the hose pushed back on. Several under-hood trim fasteners were also missing. My best assessment is that coolant sprayed onto the hot turbo/exhaust components and ignited. The vehicle has not been altered since the fire and is available for inspection at watson's in ludington, mi. I reported the fire to the manufacturer. They directed me to take it to the local dealer, then instructed the dealer not to inspect or work on it. The case was escalated internally, but as of 10/15/2026 no manufacturer inspection has occurred and no one has contacted me. The cause has not been confirmed by a dealer or independent shop. The fire occurred within the vehicle's certified pre-owned warranty period. As of this filing, the manufacturer has not provided towing, rental, or any other assistance. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

When I drive the in electric mode, I sometimes get a sudden loss of power and the system falls back to hybrid mode. Normally this is expected transition that is part of a plug in hybrid. Electric to hybrid to gas. . . As a alert driver, I plan for this not passing semi-trucks if I am low on electical until hybrid or hybrid to gas. . . The Jeep 4xe, seems to swtich after I ask for more power. . . . This delay and hesitation is dangerous. Once example, with 35% battery, at 30 miles an hour, my neighbor was backing out of her driveway, I needed to swerve and accerate to get out of the way. When I stepped on the accerator (in electric mode). . . The system seemed to stop- then the gas engine started, then it moved. . . This delay is dangerous and repeatable.

On September 24, 2026, recall 68c was completed on my Jeep Wrangler 4xe by an authorized Jeep dealership. Following completion of the recall, the first attempt to charge the vehicle resulted in an electrical fire at the charging location. During the charging event, the charger and electrical outlet melted, and the wiring connected to the outlet began to burn. The fire appears to have originated at the charging equipment and outlet. No visible damage occurred to the vehicle itself; however, the charger, outlet, and wiring sustained significant damage. Post-recall vehicle performance concerns: since completion of recall 68c, the vehicle has not operated correctly in electric mode. The following conditions were not present prior to the recall service: the internal combustion engine (ice) repeatedly cycles on and off while the vehicle is displaying "electric" mode on the instrument panel. Acceleration and overall vehicle performance are significantly reduced. The vehicle experiences severe throttle lag and delayed accelerator response. In some instances, there is little or no throttle response, followed by sudden engine engagement at engine speeds exceeding 3,000 rpm. Vehicle operation in electric mode is inconsistent and unpredictable. These performance issues began immediately following completion of recall 68c and have persisted since the recall service was performed. Additional information: I have become aware of reports from other Jeep 4xe owners who have described similar drivability and electric mode concerns after completion of recall 68c. Given the charging-related fire event and the significant changes in vehicle operation that appeared immediately after the recall was performed, I am requesting that NHTSA investigate whether these conditions may be related to the recall 68c remedy or associated software and system changes. Safety concerns: fire hazard during charging. Loss of expected vehicle performance. Delayed or unpredictable throttle response.

Subject: performance degradation and drive mode faults following recall 68c update – 2023 Jeep Wrangler 4xeto whom it may concern,I am writing to formally report a significant degradation in vehicle performance and powertrain management following the completion of the recall 68c software update on my 2023 Jeep Wrangler 4xe. Prior to the update, the vehicle operated efficiently and provided excellent torque and acceleration. I purchased this plug-in hybrid vehicle specifically to utilize electric-only (ev) mode for my daily 30-mile highway commute between [xxx] and [xxx]. However, since the recall 68c service was completed, the vehicle exhibits the following issues:involuntary engine switching: even when the vehicle is actively set to "electric" mode, the hybrid powertrain constantly forces transitions between battery power and the internal combustion engine. This behavior occurs under normal driving conditions in ambient outdoor temperatures of approximately 80°f. Loss of electric powertrain performance: the available power and torque in electric-only mode are noticeably diminished compared to the pre-recall performance levels. Compromised vehicle utility & increased operating costs: because the gasoline engine frequently overrides the electric settings, the primary functional utility of the phev system is negated. This failure to maintain electric propulsion has dramatically increased my fuel consumption and operati the safety software update deployed to mitigate high-voltage battery cell risks has fundamentally compromised the vehicle's advertised performance, utility, and drivetrain integrity. I request that the NHTSA investigate whether these post-recall performance changes constitute a systematic defect and urge stellantis/Jeep to provide a permanent software or hardware correction. Thank you for your attention to this matter and for your oversight regarding consumer vehicle safety and compliance. Sincerely, [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

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.

While driving the car in electric mode the car has very bad lag/hesitation while driving on the highway and when at a stop pulling out into traffic. After driving it in electric mode for approximately 8 miles. It will also feel as though it is not as powerful. I feel as though this could cause an accident from lack of power and hesitation.

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.

Manufacturer recall number68c NHTSA recall number25v-741 recall statusrecall incomplete cannot charge and "recommended" to not charge, or park by my own house!! waiting for solution for over a year now. Its unsafe and cannot even get good trade in value. Help me solve this or buy it back. Pay it off. Something! its unsafe for my kids and family and property. It needs to get fixed ASAP.

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.

2019 Jeep Wrangler jlu experienced intermittent can-c communication failure. Vehicle has repeatedly experienced simultaneous loss of multiple electronic systems. On September 7th 2026, while driving, vehicle unexpectedly lost electric power steering, windshield wipers activated without command, abs/tpms/esc warning lights illuminated, and vehicle subsequently would not shift into gear after stopping at a traffic light. Hazard lights would not activate. After shutting vehicle off, vehicle would not enter acc or restart normally. Opening driver’s door unexpectedly caused vehicle to enter acc. Manipulating the can-bus wiring/star connector behind the glove box has historically temporarily restored normal operation. Vehicle has previously required repair to this wiring/connector, and the failure has recurred. This has been occurring for at least 3 years and since 60,000 miles. This presents a significant safety hazard because steering assistance, shifting/propulsion, and signaling were simultaneously affected while driving. It is a known Chrysler issue (fca star case s2108000146) and should be recalled as there is a clear and present danger with this ongoing issue.

The contact called for an acquaintance who owned a 2025 Jeep Wrangler. The contact stated that while the vehicle was parked in the driveway, a neighbor saw black smoke coming from the vehicle. The neighbor called the authorities first and then called the contact, who was not at the residence during the failure. The vehicle caught on fire, and the neighbor alerted the occupants inside the residence about the fire. The fire department arrived on the scene and extinguished the fire. The fire burned several trees in the yard and damaged the concrete in the driveway. A fire report was filed. The remnant of the vehicle was towed to a salvage yard and deemed a total loss.

My Jeep Wrangler currently has a very strong fuel smell, and when the ac is on the smell is very strong inside the cabin. My kids and I became ill and had headaches. It's been parked for two weeks. Pending an inspection by an independent mechanic. We came across an article stating that a lot of 2020 Jeep Wranglers with 2. 0l motors were recalled because of the same issue but my Jeep was not recalled and I'm having the same issue. Is there anything you can do to help me?.

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.

Since the 68c recall, my 2021 Jeep Wrangler 4xe has not behaved normally and has become increasingly unpredictable. Even with a mostly or nearly full battery, it frequently will not operate in pure electric mode at lower speeds, particularly on even slight inclines. The gas engine can suddenly start when I am expecting electric operation, sometimes accompanied by hesitation, lurching, or an abrupt change in power delivery. I have genuine safety concerns with the vehicle because I cannot reliably predict how it will respond to accelerator input. There have been instances of reduced or delayed power followed by sudden engagement, which is especially concerning when pulling into traffic, crossing an intersection, merging, or maneuvering on a hill. These problems began following the 68c recall, and the vehicle's current behavior does not feel normal, consistent, or safe.

While driving my Jeep 4xe, the vehicle suddenly loses motive power without warning. The vehicle emits a chime, the "d" gear indicator flashes on the shifter and instrument cluster, the check engine light illuminates, and a message displays instructing me to shift the vehicle into park. At that point, the vehicle will no longer accelerate, forcing me to coast and maneuver across traffic lanes to reach a safe location. This failure has occurred multiple times, including at highway speeds, creating an immediate safety hazard and increasing the risk of a crash. During several incidents, I narrowly avoided being struck by surrounding vehicles due to the sudden and unexpected loss of propulsion. The vehicle is currently at the dealership, and the dealership has confirmed the condition. A sudden loss of motive power while driving is a serious safety defect that requires immediate corrective action.

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.

Absolutely terrible gasoline vapor filling the inside cabin of the vehicle causing burning eyes, nausea and feeing ill. Checked for fuel, leak, leakage recall, while there was one it wasn’t including our VIN, however, after inspection and repair, it is the exact same damage as what was indicated in the recall. Looking for a full refund for repair and compensation for danger, discomfort, safety and inconvenience of vehicle not being included in the original recall. I am appalled and insulted that Jeep dealerships aren’t more more proactive in having to appeal these dangerous situations.

The contact owns a 2021 Jeep Wrangler. The contact stated that while operating the vehicle, the engine overheated, and the vehicle was driving sluggishly with the temperature gauge indicating that the engine was overheating. The vehicle was taken to an independent mechanic who determined that the coolant reservoir was cracked and was leaking coolant. The coolant reservoir was replaced, and the vehicle was repaired. The contact stated that the vehicle failed to immediately start due to battery failure. No further information was available. The local dealer was notified of the failures, but no assistance was provided. The failure mileage was 56,700.

I am reporting repeated premature failures of the factory charge air cooler (turbo intercooler) hoses on my 2022 Jeep Wrangler ecodiesel (3. 0l v6). Within 73,000 miles, both the primary and secondary turbo charge hoses have hardened, cracked, and failed under standard boost pressure. Safety risk: when these turbo charge hoses split, the engine experiences an immediate and complete loss of boost pressure (limp mode / code p0299), severely restricting acceleration and vehicle speed. This sudden, unannounced loss of engine power occurs while driving at highway speeds, creating a severe rear-end collision hazard in heavy traffic. Failure history & repair documentation: first hose failure: replaced by an authorized Jeep dealership at under 60,000 miles (November 2025). Second hose failure: replaced by an authorized Jeep dealership at 73,000 miles (August 2026). Stellantis/Jeep treats these recurring structural hose splits as non-warranty "wear and tear," forcing out-of-pocket repairs despite the severe highway safety hazard caused by sudden power loss. I am requesting NHTSA open a safety defect investigation into the material failure rate of 3. 0l ecodiesel charge air hoses.

Vehicle went into “limp mode” as I was entering an intersection. Pressed accelerator to the floor and vehicle would only sputter and crawl slowly. Vehicle towed to dealership. My safety and the safety of others was put at risk as the vehicle, without warning, essentially stalled while driving. If there were other vehicles on the roadway, this could have easily caused an an accident with injuries or worse. Yes the problem was comfirmed by the dealership. Yes the vehicle has been inspected by the dealer and manufacturer engineer. Dealership reports high voltage battery needs replacement. Dealership states that they cannot guarantee this won’t happen again even after battery is replaced. Check engine light was illuminated.

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.

Battery pack replacement twice and engine replacement this Jeep had problems right after I got it new been in the shop 12 times over and over again they can not get it right.

While traveling at highway speed on the freeway, the vehicle experienced a sudden and complete loss of motive power/engine shutdown without prior warning. The instrument cluster immediately displayed a vehicle graphic outlined with red lines alongside an alert message instructing to shift the vehicle into park and turn the engine off. > the sudden loss of propulsion in live freeway traffic created an immediate safety hazard and collision risk while attempting to navigate across active lanes to the shoulder. > the vehicle previously had its high-voltage traction battery replaced approximately one year ago under warranty. The vehicle has been taken to an authorized dealership for diagnostic scanning and triage. Dealership said they can do a software update… that’s not okay.

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.

The contact owns a 2020 Jeep Wrangler. While the contact’s daughter was driving at an undisclosed speed, the engine temperature gauge became extremely elevated. The vehicle was towed to an independent mechanic, where it was discovered that the coolant reservoir was empty and no leak was found. The coolant reservoir was refilled, and the vehicle operated normally. The dealer was not contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 64,000.

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.
