general problems of the 2021 Jeep Wrangler - part 1

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.

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.

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.

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).

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.

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

My local dealer has all the documentation on this Jeep. It has been into the dealership many times now the check engine light is on for another problem which I am taking it in again this weekend . When I ask the dealer, I’ve been seeing things on facebook about these Jeeps having issues they just filled me full of a bunch of bull and says every vehicle has issues. I’ve ran the VIN number and found out that mine is one of them that just catches on fire plus sometimes shakes when it’s driving down the road but that’s been minor considering everything else. One time I was driving up the driveway and it felt like the transmission slipped or something. They said it was something in the four-wheel-drive that went out. This is a new vehicle. It has very low miles on it. I’ve had it going on maybe the fourth year now it’s only got 31,000 miles on it I don’t drive it very far. It’s been in the shop several times for recalls or things that’s happened to it. When I first got it, it left me stranded would not start. I’d only had it a few days. It has been a lemon from start to finish. I am terrified to drive it and I don’t have another vehicle. I paid $55,000 for this Jeep just a few years ago. I don’t know what I’m supposed to do. I desperately need help if the manufacturer is refunding people’s monies I want to make sure that I get enough money to buy another vehicle because this one is only a few years old and it’s been in the shop numerous amount of times. The other day it shimmied a little bit on the highway and I thought it was the road and now I’m reading that there’s problems with that also, it’s clearly a lemon. But as I said, I’m scared to death to drive it now. The newest development as I’ve said is now the check engine light is on. It’s only been out of the shop for maybe three weeks since they fixed something in the four-wheel-drive which I’ve never even used. I love the looks of this Jeep, but it’s not dependable so I need help.

Put a brand new battery in my vehicle - 3 days later driving on the highway had full loss of power - if said to service the charging system, and to put the car in park, then to press the brake and start button to start the vehicle. Went from 75mph to 25mph - rolled off the highway.

I was driving my 2021 Jeep Wrangler and it started running poorly. I was near the dealership. I called them and told them I was headed to them ASAP. (I was within 3 mile range). The car died in the middle of an intersection. I could not put the car in neutral to move it out of the way of traffic. I got a tow truck to bring it to the dealership. Where they told me that the coolant tube fasteners for my vehicle were gone, and that the engine was blown, including the pump. Elbow screws were missing for the vehicle and coolant was everywhere in my vehicle. My car has 46,000 miles on it. It has had every single oil change ,reported recall done and service request to complete completed. . It has been taken very well care of and has only been to this one dealership. . According to the dealership, it is not covered under my powertrain warranty, and that I must pay for the engine and other parts myself. Upon looking into this, I looked into the NHTSA and also the fca for recalls on a 2021. I found that that my 2021 would have been recalled for recall number zd8. Recall code is exactly what is wrong with my 2021 vehicle. I don’t know why they didn’t did not add my VIN number to it, but I am requesting that it be investigated to help me get this covered under warranty. I have contacted Chrysler currently they’re telling me that the engine is not available until November 17 at the earliest so at this time I am in a rental car that I am paying for. . I do believe that my VIN number for my vehicle should have been added and that it should be investigated for other owners of Jeep Wrangler 2021 and 2022 vehicles that possibly were not listed with their VIN numbers. Please help expedite. Chrysler case # 94425835. Dealer code 45091 and customer number 81103. Thank you.

2021 Jeep Wrangler rubicon, VIN [xxx] , recall p0dab-00 (hybrid/ev cell balancing performance case #[xxx], Jeep corporate case manager tiona. On 8/11/25, I brought my vehicle to freeland Jeep, antioch, TN for a separate issue and requested inspection for the open ev battery recall. The dealership gave a “green flag,” confirming no recall impact. On [xxx], the check engine light came on and the vehicle drove unsafely. On [xxx], the exact recall issue (p0dab-00) was diagnosed — the same issue we asked to be inspected. Approval for hybrid battery replacement was granted; part was ordered for 9/3 with repair by 9/5 — repair never occurred. Service advisor brian astorga claimed the part “cannot be located. ” calls/emails to service manager david beasley and case manager tiona are unanswered. The timing is highly suspicious: the vehicle failed immediately after the “all clear” inspection, suggesting potential negligence or miscommunication. We are now more than 1 month without a vehicle, which is unsafe and unacceptable. And we even had to argue with Jeep to cover a rental! requested action: require Jeep to complete the recall repair immediately or initiate a full buyback.

The vehicle has multiple critical, uncorrected safety defects: loss of motive power (rq24012), engine contamination (csn 78c), and battery fire risk (recall 68c). Incident details (r/o 6018666, 7/15/2025): my 2021 Jeep Wrangler 4xe experienced a sudden and complete loss of motive power while operating. The customer concern noted on the repair order states the vehicle "seems to loose power while driving above 30mph. . . And feel like it was going to turn off. " this failure rendered the vehicle inoperable and created an extreme safety hazard on a major roadway (us hwy 281/s37), forcing me to coast to safety. Component failure and safety risk: the failed components are the engine (2. 0l turbo), hybrid propulsion system, and electric coolant heater (ech). The dealer's repair (r/o 6018666) confirmed system instability by replacing the ech. This loss of power is directly linked to the manufacturer's known defect (csn 78c), where sand contamination in the engine can cause catastrophic failure and unrecoverable loss of propulsion. This mechanical defect is the root cause of the safety risk and is currently under NHTSA investigation (rq24012). Additionally, the vehicle is subject to recall 68c (battery fire risk), preventing safe use of the phev system and forcing me to park away from structures. The combination of these uncorrected defects puts both my safety and the safety of others at risk. Warning lamps: a 'service hybrid system' light or similar warning message appeared at the time of the incident. The problem has been confirmed by the dealer (price Chrysler Dodge Jeep ram) and is documented in repair order 6018666. The component is available for inspection upon request.

It started with the engine sounding louder then normal. Then a bad smell in the cab of the vehicle. Later found out it was a exhaust leak that was getting into the vehicle causing headaches and other symptoms of carbon monoxide. Also note the burn marks around the broken bracket that could cause a fire if not mechanically inclined to notice. Not check engine light for this. But when I spoke to the dealership it wasn't new to them. Apparently this has happened to alot of the ecodiesel Jeep and gladiators. A common problem that should be resolved before and life threatening injuries result in loss of consciousness or fire.

From the moment I drove off the lot, I encountered problems. The battery light came on immediately, requiring a replacement within weeks. I returned to the original carmax location for this service. However, this was only the beginning. Over time, I discovered the following: the driver seatbelt was not functioning properly the right rear passenger seatbelt buckle was completely missing the filters were filthy and had not been cleaned or replaced in well over a year, according to a trusted mechanic the engine may now require replacement at just 38,000 miles when I called carmax to report the missing seatbelt buckle, I was incorrectly told that my vehicle was not under warranty. This was untrue — I was well within the warranty period at the time. Despite this, I was ignored, and the safety concern received no follow-up or correction. This points to either a falsified or negligent vehicle inspection at the time of sale. Your "125+ point inspection" failed to catch multiple clear safety hazards and wear issues — or worse, they were deliberately overlooked. What’s most disturbing is that I only discovered the missing seatbelt after my sister drove the vehicle with my 5- and 3-year-old nephews in the backseat. One child had to sit in the middle because the rear right buckle was completely missing. That realization — that I unknowingly placed children at risk in a vehicle that your team labeled "safe" — is devastating. Now I’m being told that the engine may be failing — and it hasn’t even hit 40,000 miles. I was recently asked by the southlake service team to provide oil change records, which I am willing to share. But let’s be clear: an oil change receipt does not explain why a newer engine is failing at this mileage — unless something much deeper is wrong.

While operating the 2021 Jeep Wrangler under normal driving conditions, I experienced repeated overheating issues. A high-pitched noise was consistently heard coming from under the hood during operation. Simultaneously, the engine temperature gauge would spike to high, and the infotainment system displayed an engine overheating warning. When the vehicle is started from a cold start - the high pitch is constant. To prevent damage or risk of fire, I immediately pulled the vehicle over and allowed the engine to cool. Upon restarting, the overheating issue persisted, with the temperature gauge rising and falling erratically—up to four times during a 15-minute drive. I brought the vehicle to an authorized Jeep dealership service center for inspection. The following findings were documented: coolant system: high-temperature coolant reservoir found completely empty. Low-temperature reservoir found low on coolant. Evidence of coolant leakage at multiple coolant line fittings. Engine block: external head gasket leak observed. Pressure test confirmed leaks in coolant lines. Internal engine inspection: spark plugs were removed and coolant residue was found in the combustion chambers. Cylinder walls showed damage consistent with overheating. Slightly burned valves noted during inspection. Based on the findings above, the engine has suffered critical failure due to overheating and internal coolant leakage. The combination of external gasket leaks, coolant residue in the cylinders, damaged cylinder walls, and burned valves presents a serious mechanical and safety concern. Full engine replacement is required. Estimated cost: $16,000. 00 this engine failure may pose a significant safety risk due sudden loss of power while driving, potential engine fire from overheating, exposure to steam or hot coolant under hood risk of engine seizing while on motion.

June 5, 2025 stopped at red light turned green tried to turn left and the Jeep flashed the electric red bolt symbol and check engine light came on lost all power would not go when gas pedal was pushed. A/c lost power started blowing hot air and engine turned off. Restarted engine finally got it to go enough to pull out of traffic. Turned off engine opened hood checked battery cables, fuses and all was intact. Started engine drove slowly to the autozone store to have the diagnostic test done and it showed p2101 power train system throttle actuator a control motor circuit range /performance detected unexpected voltage on the throttle actuator control motor circuit also c121c-00 abs torque request signal denied anti-lock brake system u0401-00 implausible data received from ecm/pcm “a”. System was reset to be able to drive home. 6/16/25 went to start Jeep to go to work made a clicking noise check engine light on and the voltage warning sensor flashing and showed service electronic stability control error would not stay running checked battery cables fuses and restarted engine tried to back out of driveway engine would not go. Had Jeep towed to moore cdjr dealership where it was purchased from 9/2023 to have serviced found throttle body needs replaced dealership contacted several parts dealers, mopar, and other dealerships etc. To locate the part needed was advised couldn’t find the parts needed for the repair. Contacted service department and they advised they were calling national auto care my extended warranty for approval for repair. My concern is if I had been driving 65 mph and it went out I would have been in a accident when the vehicle stopped functioning. Safety of myself and other drivers would have been compromised. This is the 2. 0l turbo motor and have been advised that there are several issues with this motor and should trade in vehicle. I don’t have that option and this is the only vehicle I have.

My Jeep started leaving me stranded 8 times. The Jeep would not start but had warning lights of " service charging system" , with picture of a battery in left of dash, a wrench, engine light, and it won't go into neutral to have it towed. I had it in the shop twice, and they cannot figure out the cause. They did update the computer to cover the recall from automatic combustion. { updated the computer) . It got worse, the car is now cutting off while on. I had it towed to the Jeep dealer aging tonight . The dashboard lights do not come onto until after engine failure. This is a hybrid, I was told by crossroads to keep the vehicle charged but this has not corrected the problem.

In June 2025, I brought my vehicle to the dealership (hendricks Chrysler Dodge birmingham, al) for a full diagnostic inspection, and at that time I was told everything was fine. There were no warnings, no notes about electrical issues, airbags, coolant leaks, engine leaks, or any of the major concerns now being reported. On my most recent visit (October 2025), the dealership suddenly reported multiple “immediate attention” failures, including: • airbag system issues • electrical system failure • coolant system leak • water pump leak • engine oil separator leak these items were never mentioned during my previous full diagnostic despite being safety-related components that typically show symptoms or codes. Because these new issues involve critical components like the airbags, engine, and electrical system, my safety was put at risk. I have been driving the vehicle daily under the belief that it had passed a full diagnostic months earlier. If these problems really existed at that time, then I was unknowingly operating an unsafe vehicle. If they did not exist, then the sudden appearance of multiple major failures raises concerns about incorrect diagnostics or improper prior inspection. I have not received any warning lights except the airbag light. The dealership has not provided a clear explanation as to how these issues appeared only months after a full inspection. This has caused significant concern regarding vehicle safety, diagnostic reliability, and whether the previous inspection was performed correctly. I am requesting NHTSA review because the dealership failed to identify or disclose major safety-related failures, which has potentially placed me in danger without any warning.

The contact owned a 2021 Jeep Wrangler. The contact stated that while driving at an undisclosed speed, the vehicle lost automotive power. No warning lights were illuminated. The vehicle was started, however, the vehicle failed to start as intended. The contact drifted the vehicle to the shoulder of the road. The contact stated the rear of the vehicle was filled with smoke. The contact exited the vehicle. The contact stated that within five minutes, the fire was coming from the hood compartment. The vehicle was towed to the local tow yard. The vehicle was condemned as a total loss. The contact referenced an unknown recall repair, which had a similar failure description, however, the contact's VIN was not associated with the unknown recall repair. The manufacturer was not made aware of the failure. The failure mileage was 28,000.

I experienced an extreme coolant leak caused by the coolant inlet tube fasteners backing out and becoming loose. This is consistent with mopar recall csn zd8 for 2021-2022 Jeep Wrangler. My VIN does not seem to be covered by this recall but experienced the same issue. I request that the vins be extended to include my VIN.

Since we have had the high pressure fuel pump recall completed/replaced, there have been ongoing problems with the cooling system that cause overheating multiple times, on the same grade of road, during subsequent trips. The vehicle alerts and says it has overheated, and is stopped and allowed to cool off. Coolant is indeed low, but there are not any visible leaks and there is no puddling or areas where it appears to be leaking. We have had this issued looked at twice, several repairs completed, hoses replaced, reservoir replaced, and we are still having this issue. This appears to be something exclusive to the diesel motor, as we have friends with the same vehicle with gasoline engine that are not having this concern.
