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

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.

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.

We leased this vehicle in 2022. About 6 months into the lease the vehicle started acting like it was overheating. My stepdaughter took the car to a mechanic and they said the coolant system shows no signs of a leak. Periodically in the time she had the vehicle these symptoms would occur. Now in the summer of this year the engine seized. She was taking the vehicle to get oil changes on time except for one time she went over the mileage due. Anyway I’ve been trying to work with the dealer about the cost of repairs and who is responsible, but in the meantime I spoke with someone who had the exact same thing happen with his jeep wrangler similar year. Now this guy works at a car auction. Been working around cars. It seems this is pretty common with Jeep Wranglers. Her Jeep has been inoperable for months now.

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

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

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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 [XXX] and [XXX] 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 to: 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”.

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.

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.

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 am writing to formally file a complaint regarding ongoing and unresolved safety and reliability issues with my 2021 Jeep Wrangler 4xe, purchased from Heritage Jeep in Logan, Utah. Since acquiring the vehicle, I have experienced repeated and severe electrical failures, including: The vehicle failing to start on numerous occasions Complete loss of electrical systems (dash, lights, ignition) Batteries failing to hold or receive charge Multiple warning indicators that do not resolve after service attempts These failures have rendered the vehicle inoperable for over 65 days total since the date of purchase. Despite multiple service visits and numerous documented attempts to address these problems, the dealership—Heritage Jeep in Logan—has not been able to resolve the underlying issue. I have retained all service records, work orders, and correspondence to support these claims. This issue not only causes significant inconvenience, but it raises serious safety concerns, especially when the vehicle becomes unresponsive or loses power without warning. I believe this may reflect a defect in the vehicle’s electrical or hybrid system and warrants investigation to protect other consumers. I am requesting that the National Highway Traffic Safety Administration (NHTSA) open a formal investigation into this vehicle and hold the manufacturer and dealership accountable for the ongoing safety risk and failure to adequately repair or replace the vehicle under warranty. I was also in regular contact with Jeep Corporate throughout the ongoing issues, but they stopped responding before a resolution was reached. I have retained all email correspondence documenting those interactions.

On [XXX], I was in Fort Lauderdale, FL for vacation with my 2 friends. I was driving for about 20-30 minutes on the road, got on the highway and noticed a rubber smell. I got off the highway. I still noticed the smell did not go away. So I opened the windows & turned off the AC. Then I saw white smoke coming from the vents and smoke coming from the right side of the hood, in front of the passenger side. I proceeded to pull over and parked the car. We exit the car & saw smoke/flames coming from the right passenger side & underneath the car. I called 911. There were no warnings or indications on my dashboard that something was wrong. I got my car serviced a month prior to this fire at a certified Jeep dealership. My car was deemed a total loss by my insurance. This was completely a safety hazard to myself, two friends and the public. Luckily, there was a fire department just a few buildings down. They arrived shortly after the 911 call and put out the fire, preventing further damage to the surroundings. It was terrifying but thankfully we are all safe.

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

I took my 2021 diesel Jeep in for a Y81 Emissions recall on 02.19.24. Since then, my vehicle has had its check engine light go on SIX TIMES with a P0133 alert which refers to an O2 sensor. I have taken it in to the dealership for a resolution six times. Currently, it is set to be diagnosed and repaired yet one more time on 01.22.25. Now we are in the middle of winter and I feel like the vehicle is about to die at intersections and roundabouts when I approach them. I tried to go through an arbitration with FCA USA LLC which produces the Jeep brand and it was denied for a repurchase of the vehicle because the arbitrator felt it was not a safety issue since I still drive the vehicle and they are technically not in violation of the warranty which I did not accept as a resolution. Due to my non-resolved safety concern, I am raising the issue in this forum so hopefully something can be done and others that potentially have the same issue can reach a resolution as well. My hypothesis of the cause of the issue is when the Y81 recall happened, it tuned down the emissions output that was originally higher necessary for the vehicle to run, because I didn't have check engine lights before. By this tune-down of emissions, the engine is not able to produce the correct output to run the vehicle and thus the random lack of power causing a safety issue, and is currently adversely affecting components that are causing the P0133 O2 sensor to alert.

The engine and cluster showed and made noises indicating that the hybrid system was malfunctioning. The cluster indicated a speed limit at high speeds, but never did so. The electric drivetrain was disconnected and the handling and power were severely affected. It was dangerous because the distracting and concerning issues were during a rapid speed and in dangerous conditions with no clear remedy. The check engine, red turtle, and battery lights indicated the problem, but not beforehand. There were some warranty fixes around the battery including recall work.
