general problems of the 2021 Jeep Wrangler - part 1

When driving about 50 miles per hour on the highway, it felt like my engine suddenly gave out and my dash turned off. When it came back in, there were multiple indicator lights and a message that read "pull over safely and shift to park. " I did just that, but after that I couldn't get the car to turn back on or shift out of park. I had to have to towed to the dealer and it has been there since 10/13.

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.

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.

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.

The harmonic balancer on the motor failed and flew off the motor causing catastrophic damage to the radiator. The failure resulted in immediate disabling of the vehicle, which could have happened at high speeds or on a highway with limited access. The part that flew off the motor was also a large piece of solid metal that luckily landed in the bumper cavity, but if it would have left the engine compartment, would most certainly be a fatal projectile. Once taking it to the dealership, they told me that this is a known problem with the hemi 392 motor. Research shows this has been an issue since 2003 with this motor. The motor is found in several different stellantis vehicles. There were no warning signs of the failure prior to it occurring.

When using electric mode, repeatedly and consistently, when I try to accelerate (for example to get onto a highway) despite having the acceleration fully depressed, the car does not accelerate. After some time, the gas powered engine will rev, the rpm will shoot up and then the car will start to accelerate. If I slow down the electric engine will take back over, but then if I try to accelerate again the same thing will occur. I have videos of the dashboard confirming electric mode, delay to accelerate and eventual activation of the gas motor and rpms. This same issue was noted by Jeep technicians after the fix for a previous recall on the battery. This is dangerous, if I am not able to accelerate I can not safely drive change lanes, go onto highways, or avoid danger. It has been occurring, but my first video is from Feb 2026, and most recently July 2026.

Drove 20 miles to walmart, drove fine no lights no issues, parked went in came out to someone putting out the fire.

I went to start my Wrangler 4xe today and had a "service charging system" error. The gas part of the Jeep was running, so I proceeded to drive it. I noticed when I came to a stop, the car would not accelerate, then when it did it was violent and bucking. At a stop light it sounded like it was going to stall so I turned it off and then it would not turn back on at all. I finally got it to turn back on and drove it a little further, at one point I went to accelerate and had the pedal all the way to the floor and it would not advance. I brought it to auto zone and had a new 12v battery put in, but it did not fix the issue. After a quick search, it seems like this is a common problem with Jeep 4xe high voltage battery systems. Jeep has recalled the battery at least 3 times now and I've taken it for the first two recalls already. It was extremely distressing to try to accelerate and it not move, and could have seriously been a safety issue if I continued to drive the car. I was in another state, Jeep has no 24/7 service to call other than roadside assistance, so I had it towed to brubaker Jeep in lancaster PA, but I live in virginia and had to rent a car to get home.

1. The vehicle caught fire during normal operation. It is a 2021 Jeep Wrangler (VIN [xxx]) subject to fca us recall 21d / NHTSA campaign 26v363000, which identifies the electric hydraulic power steering (ehps) pump and its wiring as a fire source that can overheat and ignite. The exact failed component has not yet been confirmed by diagnostic, but the fire is consistent with the defect described in that recall. The vehicle is intact and available for inspection — it was towed to waxahatchie Jeep, an authorized stellantis dealer in waxahachie, TX, on June 19, 2026 and remains in their custody under repair order [xxx]. 2. The vehicle caught fire while being driven on the highway between waxahachie and ennis, texas, with two occupants returning from a boy scout trip, my husband, the driver, and our [xxx] son. The driver was forced to take evasive action, steering off the roadway into a service station to get the occupants clear and stop the fire from spreading further. This created a serious risk of burns, of a collision during the evasive maneuver, and of harm to the occupants and other motorists. 3. Has the problem been reproduced…? no. No diagnostic has been performed. The vehicle has been in the authorized dealer’s custody since June 19, 2026 ([xxx]), but the manufacturer has not completed an inspection or diagnostic. The underlying defect is the subject of an active recall (21d / 26v363000) affecting more than one million 2021–2025 Jeep Wrangler and gladiator vehicles, for which the manufacturer has stated no remedy is yet available. 4. The vehicle was towed by aaa to waxahatchie Jeep on June 19, 2026 and has remained there since. It has not yet been formally inspected or diagnosed by the manufacturer. 5. There were no warning lamps or messages prior to the fire. The first indication of a problem was smoke from the engine area at which point the driver immediately pulled off the road and saw a plume of smoke coming from the exhaust. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

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.

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.

The contact owns a 2021 Jeep Wrangler. The contact stated that while driving at various speeds, the temperature gauge rose significantly, indicating that the engine was overheating. The coolant temperature warning light remained illuminated. The vehicle was taken to a local dealer to be diagnosed, and the contact was informed that there were metal shavings inside the engine cylinders, and that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage 131,000.

Driving on the highway smoke came from under the hood in the right hand side forcing my family out on the highway keep ingulfed in flames and burnt to a crisp.

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 engine is overheating at idle speed and there's a phamtom coolant leak. We just bought this in January and are already having major issues. Seems to be a problem with the plastic coolant reservoir being near a very hot engine.

"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 video screenshots that show the gauge spikes (rpm/oil needles jumping and dropping to zero).

What component or system failed or malfunctioned, and is it available for inspection upon request? -after the 68c recall update for the hv battery failures, the vehicle has not been able to consistently maintain or provide power due to the limitation of the battery introduced as part of the recall. This is most noticeable driving in electric mode below 60% charge. The throttle behavior is inconsistent and unpredictable due to the recent updated how was your safety or the safety of others put at risk? -I was merging onto a controlled access highway and unable to accelerate after pulling into the travel lane from the merging lane due to the limitations of the battery power. The engine did not respond in time to provide power to the vehicle. The occurrence of the loss of power is unpredictable. Some times the electric battery and motor can provide the necessary power, and in others it does not respond to the throttle demand at the same state of charge with no indication of the issue. Has the problem been reproduced or confirmed by a dealer or independent service center? -it has not yet has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? -it has not were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? -no warning lamps were provided.

A recall repair was completed in 2023 related to an overheating warning. Recently, the same issue has returned. The engine cooling fan runs at a very high speed for several minutes and then shuts off, even when the vehicle is cold or operating under normal conditions. An overheating warning message appeared briefly while driving, but the temperature gauge remained within the normal range. This suggests the engine may not actually be overheating and that the issue may be related to a faulty sensor, electrical system, or control module. The problem has not yet been fully diagnosed by a dealer due to diagnostic costs, but the symptoms are consistent with the original issue that led to the recall repair. This condition could pose a safety risk because the driver may receive inaccurate overheating warnings or may not be alerted if a real overheating condition occurs. The issue is intermittent and has occurred both while driving and when the vehicle is stationary. Attempts were made to contact the manufacturer to report this as a repeat issue after a recall repair, but no resolution was provided and a formal case was not successfully established.

My vehicle is experiencing ev system failures, stalling, and system shutdown warnings that make the vehicle unsafe to operate. These symptoms began after a recall repair that was performed by the dealership. The dealership initially stated the recall was repaired, but the same symptoms have continued and have now worsened. The vehicle will display ev system warnings and will stall or shut down systems while driving. The air conditioning and other systems also shut down as the vehicle attempts to protect the electrical system. I have brought the vehicle back to the dealership multiple times regarding this issue. Despite the vehicle showing the same symptoms associated with the recall, I am now being told I may have to pay for additional teardown work unrelated to the ev system. This vehicle has become unsafe to drive, and I have requested assistance and escalation from dealership management but have not received a resolution. I am filing this complaint due to the safety risk posed by the vehicle stalling and shutting down systems while in operation.

Vehicle has gone through the 68c update and the car sometimes hesitates in stop and go traffic. Also the vehicle hesitates on acceleration almost causing an accidents more times than I can count.

My 2021 Jeep Wrangler rubicon (3. 6l etorque, automatic transmission) has experienced recurring drivetrain instability beginning at approximately 2,000 miles while under factory warranty. The vehicle intermittently exhibits a high-rpm flare during acceleration, where the engine speed increases without a commensurate increase in vehicle acceleration. The transmission then abruptly engages, causing sudden jerking. At low speeds (approximately 10–5 mph), the vehicle shudders and harshly downshifts, creating a sudden grabbing sensation. Engine rpms fluctuate during deceleration as if the transmission cannot smoothly match engine speed. Braking feels inconsistent, and at times it feels as though the vehicle is accelerating or resisting braking input before abruptly slowing. The vehicle has felt as though it would stall at low speeds and has stalled intermittently. Additionally, the forward collision warning / automatic emergency braking system has activated without an obstacle present. There have also been intermittent instances of loss of power steering assist. The engine has developed a ticking noise and a high-pitched ringing/whining sound from the engine area during operation. In January 2026, the transmission catastrophically failed and required replacement of the transmission, torque converter, cooler, and control module. The vehicle was out of service for over 24 days. Following installation of a mopar remanufactured transmission and torque converter, the same symptoms have recurred, including rpm flare, delayed shifting, shuddering, harsh downshifts, unstable deceleration, and abnormal engine noises. These conditions present a safety concern due to loss of expected acceleration, unpredictable torque engagement, unintended braking activation, intermittent power steering loss, stalling behavior, and drivetrain instability. The vehicle is currently under further diagnostic evaluation. I have multiple documents, but the file is too large to upload.

While towing a utility trailer on the highway, the vehicle suddenly lost acceleration and could not maintain normal power while the driver was attempting to pass a semi-truck. During the incident, the semi-truck contacted the trailer and shredded one of the trailer tires. Three occupants were inside the vehicle. No injuries occurred, but the incident created a serious risk of a fatal collision. The vehicle has repeatedly displayed “service electronic stability control” and other warning lights, together with loss of power and transmission hesitation/slipping. The same concern has been reported to the dealership during approximately three service visits. The dealership previously replaced the air filter and attributed the warning lights to it, but the condition returned. Dated videos show the warning condition before and after that repair. The vehicle is currently back at the dealership for the recurring safety concern.

My engine light came on shortly after my first warranty oil change August 23,2025 at the tonkin hillsboro dealership. During my 2nd warranty oil change January 9,2026 at tonkin hillsboro dealership I let them know my engine light came on after their last service and they wanted to charge me the diagnosis fee. After continued discussion learned they already checked the code indicator and mentioned possible gas cap seal and it was not fixed. Today I received an updated carfax of my recent service and saw a recall for my vehicle dated on October 30, 2025 urgent fire risk when parked. Nhtsa recall number 25v741000 manufacturer recall number68c NHTSA recall number25v-741 recall statusrecall incomplete this safety was not checked, fixed or completed within the consumer regulatory requirement of recalls while my vehicle was in service and in their observation. If the recall notice is dated October 30, 2025, there should be no reason for an oversight in providing clear communication and corrective action immediately while the vehicle was in service on January 9,2025 and communication/information before I picked up the vehicle and drove it off the lot. This is a certified vehicle that so far has not given me any confidence of proper dealership quality and car for vehicle safety and consumer CO concern.

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.

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.

After the safety recall 68c, the vehicle no longer operates as designed. In electric only mode, the gas engine engages, which is bad for the engine. This fails to give the engine time to prepare for short sudden use. When driving, the high voltage battery will lag or not produce power as it did prior. This can cause an accident (which it almost did already for myself). The acceleration lags before engaging. This vehicle performed properly prior to this software (1/1/2026) update. I don't trust or feel safe in my vehicle at this juncture. I seek the manufacturer to correct this for the safety of those who drive these vehicles.

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 '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 have owned this vehicle since August of 2021 and consider myself very familiar with the normal operation and performance of the vehicles propultion system. From August of 2021 through December of 2025: - I could operate the vehicle at highway speeds in full electric mode - I could reliably tell when the vehicle would transition to the internal combustion engine and how the vehicle would respond when it transitioned (a smooth transition) - I could have confidence in how the vehicle would accelerate when the gas pedal was pushed. I had the 68c recall performed on 12/23/25 and since the recall, the vehicle's propultion system has not been the same to the point where it is a safety concern. - I cannot operate the vehicle at highway speeds in full electric mode and in many cases cannot operate in electric at lower speeds. - when the vehicle transitions to internal combustion, the engine climbs to an unsafe rpm, then reduces rpm in stages until transitioning back to full electric. This process repeates iteslf over and over as if the vehicle is trying to find the right balance between electric and gas. These transitions cause unreliable fluctuations in speed and power and put unecessary strain on the engine. - there are times when I will go to accelerate and nothing will happen for a couple of seconds. This is particularly dangerous at intersections. - there are times when I will go to accelerate and the vehicle will start in electric for a second and then immediately jump to 4500 rpm on the internal combustion engine, jetting the vehicle forward in an unsafe manner. The dealership noted the behavior, but cannot identify any codes and the official message from jepp is that this is "normal operation. " I've driven this vehicle for over 5 years and over 60,000 miles. I can confirm that this is not normal, this is not how it always has been, and there has been a change made to the performance of the vehicle since the recall. I have videos of the behavior.

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.

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. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2021 Jeep Wrangler. The contact stated that while driving at an undisclosed speed on the highway for 45 minutes, there was an abnormal odor of chimney fire, which continued while at the stop sign. The front passenger occupant noticed there was smoke from underneath the hood. While pulling over, the steering wheel locked up, and the occupants exited the vehicle. The engine warning light was illuminated. The damper had previously been replaced, but the vehicle was well-maintained. There were no reported injuries, air bag deployment, or crash. The fire department was able to extinguish the fire. The police were called to the scene, but there was no police report. The vehicle was towed to a tow lot. The local dealer was contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 52,000. The VIN was not available.

Jeep has a design defect in vehicles equipped with the 2. 0l turbocharged engine where the coolant reservoir is positioned directly adjacent to the turbocharger and turbo heat source with insufficient heat shielding. Due to the constant high heat exposure, the plastic coolant reservoir and/or connecting plastic fittings degrade, warp, and become brittle over time, eventually leading to coolant leaks, erratic coolant temperature readings, and/or sudden coolant loss. This failure often occurs without warning, and many vehicles do not initially trigger a check engine light. In my case, the vehicle exhibited intermittent coolant temperature readings, abnormal fan operation, and heating inconsistencies before the leak was discovered. Multiple repair attempts are frequently made before the root cause is identified. Mechanics often replace components such as the thermostat housing, coolant temperature sensors, or related assemblies, not realizing the coolant reservoir heat damage is the underlying cause. This results in unnecessary repairs, significant consumer expense, and extended vehicle downtime. This defect poses a serious safety risk, as coolant loss can result •engine overheating •sudden loss of power •potential engine failure while driving •increased risk of breakdown in traffic or unsafe driving conditions numerous owners report similar failures, indicating this is not an isolated incident but a widespread design flaw affecting Jeep vehicles equipped with the 2. 0l turbo engine. Jeep has not issued a technical service bulletin or recall addressing the placement of the coolant reservoir or providing guidance to technicians to inspect for heat-related degradation in this area. I am requesting that NHTSA investigate this design defect and require Jeep to issue a technical service bulletin or recall addressing this. The vehicle was properly maintained and not modified and the issue occurred at relatively low mileage.

Bolts came loose on thermostat housing caused all the fluid to leak out when looked up seems to be a common problem on these Jeeps.

I was driving on the freeway, 65mph, in los angeles and the '21 Jeep Wrangler 4xe started showing a bunch of error messages telling me to safely pull over, loss of propulsion, etc. I lost power and was unable to drive past 38mph. Upon getting to the end of the off-ramp and before coming to a full stop, the vehicle threw itself into parking gear. I shifted to park, and it wouldn’t shift out of park, while I was blocking traffic on the off-ramp, which could have been a dangerous incident. I required a tow truck. There was a check engine light and a 12v battery light while I was bricked. The tow truck was unable to jump start it. The dealer provided a pre-scan report showing stored codes p0607 (ecu internal performance) and p1b13 (park-by-wire unintended out of park). Refusal to repair: the dealer just replaced the 12v battery and "cleared the codes" (per their invoice). There is a known TSB 08-054-22 (NHTSA id 10248015) specifically relating to code p0607 software logic, but they refused to look into it further. I didn’t have confidence in their diagnosis, and when requesting them to do a safety test drive with me, they refused. When I pressed for safety verification, the service director told me to “leave the dealership and never come back. ” I was genuinely concerned about the safety of this vehicle and their lack of investigative diagnosis, specifically their refusal to verify if the TSB was performed to ensure the hybrid control modules have up-to-date software. They refused to offer any help and just told me to “take the vehicle and leave. ” I don’t believe it’s normal for a car to lose propulsion from a weak 12v battery while driving. There seems to be a more complicated communication issue (p0607) that is happening, and it very much concerns me as losing propulsion on the highway is very dangerous.

I purchased (traded into) a 2021 Jeep Wrangler on October 31, 2024. The vehicle already had an open safety recall (68c) at the time of purchase. Shortly after, the vehicle began experiencing severe and dangerous safety failures. While driving, the Jeep suddenly goes into “turtle mode,” loses power without warning, and drops to 7–12 mph in traffic. The engine light comes on and the vehicle becomes almost undrivable. This creates an extremely hazardous situation where I could be rear-ended or left stranded on the road. This is a serious safety risk to me and to other drivers. I contacted Jeep/stellantis recall customer care to report the issue. Only after calling did I receive an email telling me I must pay out of pocket for a rental vehicle, even though the vehicle is unsafe and the recall remedy is not available. I immediately responded saying I cannot pay upfront. Since November 25, Jeep/stellantis has ignored my messages completely. The vehicle remains unsafe, undrivable, and under a recall with no available parts. Jeep has refused to provide a direct-billed rental or any safe alternative transportation. I have been left without a usable vehicle while the manufacturer fails to communicate or offer assistance. This is a major safety defect, and the lack of manufacturer response puts me in danger. If this vehicle loses power in traffic again, it could cause an accident. I am requesting NHTSA intervention because Jeep/stellantis is not addressing this safety issue, not providing a remedy, and not honoring their recall responsibilities. Symptoms: •sudden power loss •turtle mode activation •speed dropping to 7–12 mph unexpectedly •engine warning light on •vehicle unsafe to operate manufacturer failure: •recall 68c remedy unavailable •denied direct-billed rental •required me to pay upfront for rental •no response to my communication since Nov 25 •left me without transportation.
