2023 JEEP GRAND CHEROKEE Engine Problems

For the second winter (2 out of 2) this vehicle has entered FORM mode - Fuel Oil Refresh - and fails to operate as a hybrid car until- if last year was the indicator - Spring and warmer weather. Ostensibly due to running in electric mode for too long, FORM is an engine and fuel safety measure. Since this vehicle was under recall 68C until earlier this week and had not been operable in electric mode at all since September, this excuse fails demonstrably. It has been in FORM since the recall was completed. Having a Jeep in winter that is not operable in electric mode in snow and ice when the potential exists that gas mode doesn't function and the 24 "reserve" miles are not available in electric mode, poses a significant risk. Secondarily, in last winter and this, hybrid use is unavailable for months.

Local Dealers are unable to resolve the recall on timely basis due lack of parts, lack of loaner or rental cars. Weather, sense of urgency. This is a serious safety recal of potential battery fire and suddenly stop while in motion. Need to do something!

On approximately November 15th 2025, I took my 2023 Jeep Grand Cherokee 4xE In for a routine oil change and tire rotation to Fred Martin Super Store in Barberton , Ohio. Upon completion on the service I was told that there was a recall on my vehicle and I was not to park in my garage or plug the vehicle in due to risk of fire coming from the Hybrid Battery. I immediately called the service department at Fred Martin Super Store in Barberton Ohio to see if this recall was accurate. The Service Department Rep did confirm verbally that there was a recall and again NOT TO PARK IN MY GARAGE OR PLUG THE VECHILE IN DUE TO FIRE RISK. I was told the parts were not available to fix the problem at this time. This vehicle is not safe to have on or near my property and is not functioning the way it is intended. I have contacted Jeep multiple times and filed multiple grievances to ask for a vehicle buy out or a lease termination with out penalty and have been denied. This repair has not been done or remedied in a timely manner, and is still unsafe to have or drive.

The contact owns a 2023 Jeep Grand Cherokee. The contact received notification of NHTSA Campaign Numbers: 25V741000 (Electrical System) and 25V766000 (Engine); however, the parts to do the recall repairs were not yet available. The local dealer was contacted, and the contact requested to trade the vehicle, but the request was denied because the vehicle was under recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue and offered to reimburse the contact for vehicle rental expenses within a specific price range, but the price range that the manufacturer provided could not cover the rental expenses of a vehicle that could accommodate the contact. The contact had not experienced a failure.

Vehicle recall for potential fire risk if charging vehicle battery, was informed by email from Jeep that the vehicle is not safe to drive. No solutions given

2 current recalls on my vehicle 68C and 78C are life threatening and the vehicle may catch on fire. Visiting the dealer today 12/6 - there is no solution for either. This vehicle is unsafe and the manufacturer is not providing any solution or alternative. I would expect either a solution/ a loaner or a buyback

My Jeep hybrid is under an active safety recall with no available remedy. The manufacturer has instructed owners not to charge the hybrid battery system, which means the vehicle cannot be used as designed. I am continuing to make loan payments on a vehicle whose primary advertised functionality has been disabled due to a safety defect. I have contacted Jeep/Stellantis repeatedly through their recall assistance lines and have been transferred, disconnected, or told to call numbers that do not resolve the issue. No timeline or interim remedy has been provided. The vehicle is materially impaired, and the lack of a fix poses safety concerns and financial harm to owners. I am requesting NHTSA intervention due to the absence of any manufacturer solution or support.

The vehicle has an active safety recall related to a potential high-voltage battery fire. The recall warns that the battery pack may contain damaged cells that could lead to a vehicle fire under certain conditions. The manufacturer instructs owners not to recharge the battery and to park the vehicle away from buildings or other vehicles due to the fire risk. The defect puts my family and others at risk because the vehicle cannot be safely charged, cannot be parked near structures, and may pose a spontaneous fire hazard. This significantly limits the ability to drive or store the vehicle normally. The issue was present before I purchased the vehicle, and the recall was active at that time. The problem has been confirmed by the manufacturer’s recall documentation. I have contacted dealerships and the manufacturer, but no remedy appointment or software update has been provided, and a replacement high-voltage battery has not been scheduled. Warning messages and restrictions were communicated through the official recall notice. There have been no repairs performed, and the safety risk remains unresolved.

I am formally requesting immediate review and investigation into multiple unresolved safety defects involving my 2023 Jeep Grand Cherokee 4xe, VIN [XXX] . Jeep has acknowledged a hybrid-battery fire-risk recall affecting this model, yet there has been no available remedy or repair timeline, leaving the vehicle unsafe for regular operation and posing risk to myself, my family, and others around the vehicle. Primary defect — High-voltage hybrid battery fire risk (UNRESOLVED) My vehicle falls under an active hybrid-battery safety recall involving potential internal failure of the high-voltage traction battery capable of causing thermal events or fire while parked or in motion. Despite this being a critical safety hazard, Jeep/Stellantis has: Provided no repair or replacement timeline Offered no interim mitigation beyond advising parking precautions Provided no alternative transportation or safety guarantee This leaves me with a vehicle that cannot be safely used, parked near structures, or charged, effectively removing the primary functional design reason I purchased a 4xe plug-in hybrid. Additional unresolved safety-critical issues In addition to the fire-risk recall, my Grand Cherokee 4xe has experienced: Steering component issues, including instability and safety concerns while driving Suspension-related defects, including risks tied to coil-spring recall applicability Loss of hybrid system functionality, severely limiting drivability and efficiency Multiple disruptions causing loss of use, travel restrictions, confidence in safety & reliability These combined failures demonstrate systemic integrity concerns that extend beyond the battery recall alone. Why NHTSA’s involvement is needed Because Jeep has failed to present a repair path or a timeframe — and because this defect can escalate to vehicle fire, immobilization, or sudden failure while driving — I believe there is sufficient cause for expanded review and enforcement action.

I am reporting ongoing safety concerns with my 2023 Jeep Grand Cherokee 4xe (VIN: [XXX] ) related to repeated high-voltage battery defects and loss-of-power risks. The vehicle has already been subject to NHTSA Recall 25V576 (FCA 73C), which I completed, but the underlying electrical/battery issues continue to raise serious safety concerns. As of November 2025, my vehicle is now listed under NHTSA Recall 25V776 (FCA 68C), which involves a defect inside the high-voltage battery cells that can lead to a vehicle fire even when parked and turned off. Stellantis has instructed owners not to charge the vehicle and to park it outdoors, indicating a significant and ongoing safety risk. No remedy is currently available. Additionally, a separate recall—NHTSA 25V766 (FCA 78C)—was recently announced for 2023–2025 Grand Cherokee 4xe vehicles regarding potential engine contamination that can cause engine failure or fire. While my VIN is not yet listed under 25V766, my model year and 2.0L hybrid powertrain fall within the affected range. These overlapping recalls, combined with recurring electrical issues across the 4xe lineup, reflect a broader pattern of safety defects that place owners at risk. The cumulative trend is alarming: multiple consecutive battery-related fire recalls, prior software updates that failed to resolve the issue, and now possible engine contamination. These issues continue to undermine confidence in the vehicle’s safety, reliability, and long-term performance. I am submitting this complaint because the vehicle remains subject to an open fire-risk recall with no repair available, and the expanding list of related recalls suggests a systemic problem with the Jeep 4xe’s high-voltage and engine systems. I am seeking NHTSA’s further review and investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This vehicle is a danger to drive, and there is no information on when they will fix it. I have taken the battery in to fix it before and it took over 2 weeks to repair, and more problems with more recalls. The engine is said that it can cause fire like the battery. This vehicle is not safe to have and continues to be a severe safety problem for me and my family, Two of the recalls right now they have no idea how to fix. It is not fair that I am paying for this vehicle and I can't even drive it.

on 10/24/2025 my wife and daughter were in the vehicle driving to her school. My wife was on the phone with me when she stated the car was reving really high and sounded like it was going to blow up how loud it was. she was driving at about 25-30 mph when the car suddenly jerked and shut off completely, the battery light turned on and the check engine light flashed before it shut off. she was able to brake and roll to the side of the road. I had instructed her to keep her foot on the break since it was not letting her shift to park. We stayed on the phone as i contacted jeep directly and get a hold of a rep she said she was able to put it in park and she tried to turn the car on and she was able to turn it on after 10 min. She drove with the hazards on to my daughters school and dropped her off i told her park the car and don't use it until i get home. I got home on 10/26/2025 and the light was off i made an appointment with jeep for that week 10/31 and they stated they were unable to find anything in the computer for the issue that had occurred instead they saw a issue with my heating and it was pump. i have a case open with jeep and they have yet to return my call after a week of non stop calling, i emailed stelantis but they stated they cant assist has to be jeep directly. i would love some help with this as the car has been to the dealership three time for multiple issues and recalls that they stated they did and still show are not done. i have a schduled appointment for the 68c but there is no remedy yet.

Car stopped in mid drive and warning light came on telling me to pull car over to side of road and restart.

Egine stalled 2 times on the freeway

Since purchasing the vehicle in January of 2024 , I have had the same repeated safety issues that the dealership and Chrysler were made aware of . I was told that no other vehicles of my make and model had the same issues so I was not listened to . While driving vehicle has slammed on the breaking system for no apparent reason at different speeds. Last time this happened I was on the thruway doing 65 mph. This has happened over 10 times and has been extremely scary and upsetting. The Hybrid system alert has flashed over 30 times and the vehicle has stalled with loss of power. The transmission either jerks or there is a large lag of power -sometimes gas pedal needs to be pinned in order for vehicle to go forward. I have complained to the dealership and Chrysler about the safety issues and how the battery has not work as expected upon purchasing and all the safety issues. I have been mislead by Chrysler on the performance and use of the vehicle. I have asked for a resolution for over a year- lemon law, buy back , but I have to continue to drive an unsafe vehicle. Complaint # 1650529

There is a loss of power in the moment the propulsion changes from electric to gas followed by an error message to "service hybrid electrical system". Dealer inspected an found there is currently no remedy. Seems to be a known issue by now.

Two instances: 1) While reversing out of a parking spot, several warning lights flashed at once, including Power Steering System disabled, Service Hybrid Engine System, and two others - lost power steering. I parked and restarted the car and it drove normally. 2) While in park, the car started but would not shift gears and it would not turn off. It was stuck in this position for 10 minutes until the ignition button finally responded and shut off.

Vehicle randomly will not shift from first gear to second gear. This has caused very high rpm’s in first gear and I have almost been hit from behind each time. I must put flashers on, pull over, shut engine off and restart to clear the issue! It is Very Dangerous! It has been to the dealership to be fixed, but they have been unable to duplicate the issue

I am writing to express my serious concerns regarding the safety of my Jeep. My vehicle has been to the Jeep dealership approximately five times for the recurring Service Hybrid System Error. Most recently, in August 2025, I received this error again along with a check engine light. Each time this error occurs, I notice that my Jeep drives differently, which raises concerns about its reliability and safety. At present, my Jeep has been at the dealership for approximately 25 days. The dealership has indicated that the issue is related to the 73C code. Despite repeated visits, the problem has not been permanently resolved. I am very concerned about my own safety, as well as the safety of others on the road, particularly because I have been informed that my Jeep is part of the 1% recall group. The ongoing malfunction makes me uneasy about driving the vehicle, and I strongly believe this presents a potential hazard. I respectfully request urgent attention to this matter and a clear resolution to ensure the vehicle is safe to operate.

Backing into a parking space in reverse the vehicle all of a sudden begins to accelerate forward with the gear selector showing "R" illuminated almost causing me to hit 2 cars parked in front of me. After putting the vehicle in park and reverse again i was able to park and then the vehicle gave a "service hybrid system" warning and then stalled out. I had no issues prior to this and it seems the 95B recall had something to do with it as I had this performed a week prior. It has a stored code for " digital input crash " according to the dealer but they said it is deemed safe to drive. I don't think so.

This vehicle continues to have electrical issues which effects the drivability. For the current service visit, the vehicle was taken in due to “shut down” or “shudder off” as if the car had completely been downshifted and lost power while in full drive mode causing a driving interruption. This driving interruption causes a concern for safety. As of today, the vehicle has been in the service department for 56 days. Red wrench appears each time with "Service Hybrid System", check engine light. Discussions with service department: "No definitive fix" ..•B273C-00 Meaning: (one of the codes) The code specifically points to an issue with the digital crash input, meaning the vehicle's computer is detecting a "crash" event, even when one hasn't occurred. •4xe Specific: This code is frequently seen on Jeep 4xe models, likely due to the complexity of the hybrid system and its interaction with the ORC.

I was driving my Jeep grand Cherokee 2023 at night on the 580 freeway in Northern California. Was traveling about 65 MPH. When the vehicle lost all power. I was barely able to pull off to the right shoulder still was partially in the right most lane. After multiple attempts of Restart the vehicle, it did restart after about 10 minutes. I’ve taken the vehicle in to the nearest dealership on a flatbed truck. It has been there since the beginning of June. Jeep is unable to repair the vehicle sighting a software update needed for the hybrid system that they have not released yet. This problem will apply to any 4XE vehicle by Jeep. Vehicle is not safe to operate on public roads. Jeep does not seem interested in accelerating the fix. I’ve been waiting nearly 3 1/2 months.

1. Driving freeway, Lightening bolt warning, ETC came on lost power. 2. At home level 2 charging, charge to 100%. Next day EV charge down to 85% lost 15%. Car sits 3 days down to 1% EV charge. Discharging for no reason. 3. Took to dealer, check for codes. No Fix available. Dealership, took car and put me into rental. I was told unsafe to drive and told may be 2 to 3 months before fix will be available. Currently dealership has 3 other cars taken off the road. One has been there since June. All recalls had been done!

The contact owns a 2023 Jeep Grand Cherokee. The contact stated that while driving approximately 70 MPH, the vehicle lost automotive power. The contact stated that two unknown messages were displayed on the instrument panel. The local dealer was contacted, but the vehicle was not diagnosed or repaired due to the costs. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

As I was driving in a parking lot, the service hybrid error popped up and then suddenly the vehicle was showing to press brake & hit start button. The vehicle began slowing down and even while pressing the gas the vehicle wouldn’t do anything. I was able to coast into an empty part of the parking lot. The vehicle then wouldn’t go into park. The emergency brake engaged without me doing anything. Then it kept telling me to press brake & hit start button but it wouldn’t do anything. The veg hole seemed to be on. But acted as if it was off. I sat disabled in the parking lot for 5-10 minutes before it would turn back on and let me resume normal activities.

In February 2025, my jeep would flash a “Service Hybrid System” code that would last about 3-5 seconds and disappear. This happened about 4-5 times over the next few months, code would not stay up and vehicle seemed unaffected. On June 10, I was driving with son on a highway about 60 mph when my car completely shut off, no power to engine, no power steering- absolutely nothing. We experienced a very aggressive jerk when this happened and I limped the vehicle off to the shoulder- we live in a remote area and I had no cell service. I was able to restart my car and drove it in “e-save” mode home. The next day, I drove my car again and had my son and daughter in the vehicle and the same exact thing happened. I was driving about 55mph around a corner with a large semi coming at me in the oncoming lane and my vehicle shut off and lost power and power steering. I was terrified that I would veer into that truck and there was not a shoulder readily available. We had to yet again limp the vehicle a few yards around the corner to pull off and I did not have service. So I had to walk to call my husband to pick my children up. The car has been at the dealership since then and told there is a digital crash code showing with no eta on a fix. Stellantis has denied a buyback yet my car has 26,000 miles on it and is under warranty with no eta on fix. Vehicle is unsafe to drive and unfixable for 60 days now.

Vehicle wouldn’t go into gear June 2025 was towed due to service engine, abs braking error, service hybrid error. Messages were cleared and declared “no fix” wait for Stellantis update. 7/2025 vehicle service hybrid went on, vehicle lost acceleration when turning onto road. Brought back to jeep service indicated “no fix” Stellantis/jeep aware of issue. Customer states SERIVE HYBRID LIGHT TURNS ON AND THE VEHICLE IS LOSING POWER ON AND OFF VERIFIED CONCERN, CODE B273C-00, DOCUMENTATION FROM JEEP THIS ISSUE, IT IS A KNOWN ISSUE WITH NO REPAIR AVAILABLE AT THIS TIME, IT IS NOT RECOMMENDED TO PARK THE VEHICLE INSIDE UNTIL A REPAIR CAN BE PERFORMED Warranty COURTESY VEHICLE INSPECTION Section: SEE ATTACHED KNOW YOUR VEHICLE REPORT FOR INSPECTION RESULTS Warranty Claim Type:

Hybrid electric system warning light on while driving with my family on the highway, difficulty with the rear seat headrests, fresh engine oil residue on the underbody. On two occasions, the vehicle remained on and was unresponsive, and all the lights on the dashboard came on, displaying lights and warnings for faults in the hybrid system and battery. It didn't respond when I tried to turn it off. as this may put my safety and that of my family at risk

Vehicle loses power and warning lights come on “maintenance on the hybrid system”. A little red wrench appears down the lower left corner. It all goes away after about a minute and a half vehicle only loses power for a brief moment.

My 2023 Jeep GC Overland 4XE was at the Jeep service center for the same issue in a week. I get a Service throttle control warning, CEL, then every warning light on the dashboard lit up. It happened on my driveway the other day and I would not drive. I had Jeep roadside tow it to a Jeep service center. On 7/9/2025 I picked up the Jeep. Service tec said no open recalls, no software updates and the throttle body module was reprogrammed. A 14-mile test drive was done and the codes did not return. Shortly after pickup, while driving at 65 MPH on the thruway, I got the same error message, Service throttle control along with a check engine light and all warning lights again lit up. The Jeep displayed a reduced power warning, and many other warning but I didn’t have time to look at the dashboard. The vehicle slowed to a crawl in limp mode at 23 MPH, the steering became very heavy and slow to respond. I was able to quickly move over to the shoulder, and I was almost rear ended by a tracker trailer. I got off the thruway, shut the engine off, then back on and was able to get full power back. I immediately drove it to the dealership service center. This is NOT safe vehicle to be in and there are many other reports of this happening.

While driving, the vehicle sends a message that the automatic cruise control has shut down, the car starts slowing down and doesn't respond to pressing on the gas. Only recourse is to move off to the side of the road, shut everything down and turn it back on. The batteries show two miles left on the electric system. This is the second occurrence. Both have occurred at highway speed.

The vehicle is a Jeep Grand Cherokee 4xe plug-in hybrid SUV. While driving in heavy traffic on a 45 mph road, the vehicle suddenly lost propulsion, with the dash lighting up with a large "Service Hybrid System" warning. After several seconds of no response, with traffic trying to work its way around my stalled SUV, the vehicle began to move again, albeit very slowly, just enough to limp it to a side street. After another 30 seconds or so, the problem cleared itself and the vehicle returned to a normal state of propulsion. I took the car to the dealer where I left it for more than a week. Apparently this is a known issue, and a code appeared (B273C-00, Digital Crash Input), but they were not able to replicate the issue while they had the vehicle and so they just reset the code. The automaker is also aware of this problem, but doesn't deem it severe enough to issue a warning to customers or provide alternative transportation while a fix is developed. The dealer's advice is to let them know when it happens again. At this point, I don't feel the vehicle is safe to drive, and it will remain parked until a fix is available.

When my plug-in hybrid vehicle’s service engine light came on, an authorized Jeep Dealership diagnosed and fixed the electric coolant heater then also performed a software up to address the recall 95B/NHTSA 24V-720. In less than 2 weeks, my vehicle flagged a hybrid system error code “B273C.” The Jeep dealership immediately impounded my vehicle per the regional Stellantis technical team’s orders. My vehicle has been held at the dealership for over a month with no repairs or timeline for when a repair will be available. It’s unacceptable for a custom built fully paid off vehicle (2023 JGC 4xe Summit) to become such a huge liability and poorly reflects on the Jeep/Stellantis brand. There has been no support from their case management team and no urgency/ timeline provided for when this issue will be resolved. When manufacturing defects result in making a vehicle un-driveable, the manufacturer should prioritize finding a solution and provide customers with a rental of equitable quality to ensure the Jeep brand experience is maintained. Most importantly, for a vehicle that is only 2 years old, it is concerning from a safety perspective that it has had so many issues with the hybrid system for which the manufacturer has no solutions available.

BELOW IS THE LETTER I SENT TO STELLANTIS. I am writing to file an urgent and formal complaint regarding ongoing, severe safety and functionality issues with my Jeep 4xe , leased through Stellantis Financial. These issues have not only rendered the vehicle unreliable, but they have also endangered my life, the lives of my children, and the public-particularly as I work in an elementary school setting where safety is paramount. Most alarmingly, my Jeep 4xe recently reversed on its own at an accelerated speed without input, and would not stop until I prompted the brakes repeatedly. Had a child or pedestrian been behind the vehicle, the incident could've resulted in severe injury or death. As a parent and educator, this experience was traumatizing and has left me fearful of operating the vehicle in any public or residential space. Additionally, my vehicle frequently enters "turtle mode" (reduced power mode) without warning, significantly increasing my risk of being rear- ended in traffic. This unpredictability is unacceptable for any vehicle-especially one marked as a safe, family-friendly hybrid. These critical safety failures began shortly after the recall involving the vehicle's battery. Since then I've experienced: *Multiple simultaneous sensor malfunctions *Reduced driving speeds and performance *Inability to charge the vehicle on a professionally installed Level 2 charger *Recurring shop visits without permanent resolution While earlier issues were inconvenient, they pale in comparison to the dangerous and erratic behavior of the vehicle now. Despite repeated attempts by service technicians to address these problems, each "fix" is followed by a new or recurring issue. This pattern shows that the vehicle is fundamentally flawed and no longer safe to operate.

Had 60 miles to empty of gas and slowed down while entering a turn lane. All the electronics flashed a few times, forced the car into park (while moving) and then would not turn on to drive. Music continued to play, car would not turn off or restart, AC stopped working, and was unable to shift into neutral to get out of the road. Was almost hit by multiple cars getting into the turning lane expecting me to drive like everyone in front of me.

I was traveling on the highway at highway speed during peak commuting times when a notice to service hybrid system was displayed on the gauge cluster. The vehicle then lost all acceleration and shut down. I had to safely navigate to the side of the road with zero ability to accelerate or brake in fear of not being able to get off the roadway safely. I was automatically shifted into park once I reached a speed of around 5 mph.

The vehicle has been regularly throwing an error saying Service Hybrid System and having a massive stutter in power while the hybrid motor shuts off and the engine is started to try and take over immediately. The vehicle has been in the shop for this previously, only to be returned to me saying they don’t have a fix for the problem and to continue to drive it. This happened again at highway speed and caused a near immediate loss of 10-15 miles per hour and were it not for evasive driving on my part and the other car, would have caused an accident. This powertrain has major issues that continue to happen.

Car was recalled 95B. Recall completed in 1/25. Engine light 2/19/25. Car was held until 5/12/25. Had to trade car in for a lost of 6K dollars

When accelerating at highway speeds there is a significant power lag when the vehicle switches from between the internal combustion engine (ICE) and the electric motor causing deceleration in the vehicle. This is typically followed by a sudden surge in power causing rapid acceleration. This causes unpredictable speed and makes merging onto highway traffic difficult. When this issue occurs the "Service Hybrid Electric Vehicle System" warning lights illuminates. After several miles, the warning will turn off, but this occurs off and on when changing lanes, merging, or braking in heavy traffic. This typically only occurs at highway speeds when the vehicles transfers between ICE and Electric power frequently and has not been observed at normal city street speeds. The sporadic acceleration performance makes this vehicle dangerous to drive at highway speeds unless the electric motor is turn off. The car has been returned to the dealership numerous times to address this issue as it is still covered under warranty. However, they have informed us that "The code present in the car is currently under investigation by Chrysler. The Chrysler representative told us not to change any parts until Chrysler makes a decision on a potential recall." Despite repeated calls with Stellantis / Jeep customer service who promised us to expedite parts to the dealership for resolution, we are stil left driving this unsafe vehicle. This problem arose within 48 hours of the battery recall maintenance being performed and has been recurring ever since the repair.

We leased a 2023 Jeep Grand Cherokee 4xe in June 2023, and since that time the vehicle has been a chronic source of mechanical and electrical failure. Over the past two years, it has been in for service 11 times, spending more than 115 total days in the shop, with at least 9 repeat issues—largely related to high-voltage interference and hybrid system instability, from our research. The problems began before we ever took possession, with a service record at just 12 miles on the odometer showing a repair to the Integrated Dual Charging Module (1890169A). Since then, we've experienced a cascade of issues affecting sensors, control modules, cameras, switches, and critical vehicle systems—many of which appear to stem from electromagnetic interference (EMI) related to the hybrid platform. Key repairs have included: Park Assist and ADAS control modules (09/28/23) Reprogramming of multiple modules (backup camera, backup sensors) (01/25/24) Backup view camera replacement (02/16/24) Fuel system pump and lighting issues (04/05/24) High-voltage recall 95B, battery coolant pump, wiring harness, battery fire risk & issue (01/30–04/01/25) The final straw came on 05/09/2025, when—while driving 70 mph on the freeway—the vehicle suddenly shut off without warning. We lost all acceleration and power, forcing us to drift to the shoulder in traffic. It took multiple restart attempts and a wait period before the vehicle became responsive again. This was not only terrifying—it was dangerous. The next day, the Jeep dealer where the vehicle was purchased, picked up our car, and we’ve received no update on its status. It is currently undrivable, and we fear it’s unsafe. We previously filed for arbitration for with NCDS (March 2023), which was denied. The situation has deteriorated significantly since then, and we are now filing a second arbitration, alongside this formal NHTSA safety complaint. Certified letters sent to the manufacturer earlier this year have gone unanswered.

My cars dash had a lot of lights turn on and my car just shut off while I was driving I took my car to the dealership and was told that they couldn’t find anything wrong with it. About six weeks later my car just turned off again while I was driving but this time only the service hybrid light turned on and quickly turned off. I just called the dealership and will be dropping off my car again.

On the highway from Chicago to Boston while driving 70 MPH my car had LOST ALL power. I was barely able to get car from left lane to right side of road. Truck almost hit us. We immediately reported incident to our dealership and their response was “we have nothing but problems bring the car in”. We were 300 miles away and they said there was nothing they can do. I restarted car and appeared normal. On way home outside Chicago on Highway at high speed we lost all power AGAIN. Started back up and returned home and called Field dealership in Glenview and Chrysler corporate. We brought Car in and they have had it for week with no solution or phone call.

Monday 4/28, as i was driving at approx. 35-38 mph the vehicle came to an abrupt and hard stop, like someone just pounded on the brakes, the engine ceased running. A large red wrench looking icon and something about the battery flashed very quickly on the screen. After a matter of time (please note this was very frightening,, and am unsure of the elapsed time) the car restarted and I continued very slowly to a corner where I could pull off the road and contact the dealership. At the rate of speed I was traveling I was forcefully slammed into the steering wheel, there were cars behind me and in the adjacent lane. My dog in the rear compartment and in her kennel was also forcefully thrown. This vehicle has had on going battery issues and many others as well. This is not the first report I have filed. Vehicle has been at the dealership for one week, I had to insist upon a loaner which they could not provide. Jeep has a program for a comparable vehicle which they set up and which has not provided a comparable auto. I have had no word from the dealership as to repair and issue found. The ongoing safety issues with this vehicle and it's battery system are totoally unacceptable for me. The jeep has spent 3.5 months from 10/14-mid 01/15 parked due to fire or explosion possibility. It has been in the shop repeatedly for up to two weeks at a time with heating and cooling issues. This latest is just another in a long stream of problems unaddressed proprerly by the Jeep corporation. As the vehicle is still in the shop at the dealership I have no items to download at this time.

Since purchase the vehicle has had a number of electrical issues. From non functioning automatic mirrors, and memory seating, to blacking out infotainment systems to the bigger recalls. Jeep issued a recall notice early October of 2024 for the High Voltage (hybrid) battery. The recall advised customers not to charge the vehicle due to risk of fire. The hybrid feature was the main reason for purchasing this specific vehicle. With my wifes daily commute well withing the batteries capacity we were filling up at the gas station about once a month. Now being unable to charge the vehicle we were filling up more than weekly. This obviously increased the cost of ownership quite a bit. This also greatly decreased the performance of the vehicle as the electric motors provided significantly more power to the underpowered 4 cylinder gas engine. At some point I debated charging the vehicle anyway but being that my home charging area is directly below my [XXX] sons bedroom I ultimately decided against it. Brought the vehicle to the dealer in November of 24 and they refused it as no repair had been released. I tried to stay on top of things, following multiple web forums to have the most up to date information. When I knew that the fix was to be released in the first week of the new year I attempted to get ahead of it and make a service appointment. The dealer would not allow this even though I knew the fix would be available. By the time the “fix” was formally release and I was able to call to make an appointment they were nearly 2 months out from their first available date. After Jeep "fixed" the recall we have been getting intermitent "service hybrid electric vehcle system" warnings on the dash board as well as random losses in power to the engine and or motor. Brought back to dealer where they acknowledged software issue but had no fix available. They determined it was "safe" to dirve and had me take it back.

While idling (vehicle running in electric mode) in park, for approximately 10 minutes we attempted to put the car in drive. The vehicle acted as if it needed to be turned on, displaying the message "Press Brake and Push Button to Start" while also displaying a red battery light. Different warning messages came up showing Traffic Sign Assist Unavailable and others. We could not turn the vehicle off even with holding down the start/stop button, were unable to shift the vehicle either. Finally after ten minutes of pressing the start/stop button the vehicle finally shut off and we were able to restart it with no issues. The next week as I was driving, I would randomly get a warning light with a red wrench and a message that said Service Hybrid System. Both instances have happen two additional times. The vehicle is now sitting at the dealership and they are unable to diagnose the problem. This all has occurred after the 95B recall work was completed. This is a safety issue as the vehicle will not shut off and won't shift. So if the vehicle is parked inside of a garage and idles and then doesn't shut off that will lead to carbon monoxide leaking into the houses. Or being stranded somewhere unable to move your vehicle.

A couple months ago our check engine light came on. Through going to the dealership and a local mechanic we found out that it's an electrical issue as well as a safety issue. The wire connections have failed. This led to the grill shutters being forced open and if they close there will be no air going to the engine which will cause the engine to seize and/or a fire, which would lead to an accident and/or death. This isn't a safety recall at this point and this is a very big concern.

Report: Jeep Grand Cherokee 2023 table number [XXX]. Vin [XXX] Piston malfunction. **Vehicle:** 2023 Jeep Grand Cherokee Tablet:[XXX]. Vin [XXX] **Date of purchase** February 2023. **Problem:** Piston malfunction That began in September 2023. **Dealer:** Alberic Colón Chrysler, Jeep, Puerto Rico **Event timeline:** 1. September 2023: The malfunction of the piston in the Jeep Grand Cherokee 2023 began. 2. September 4, 2023: He visited the dealership, Alberic Colón, to report the malfunction and request repairs. The dealer did not adequately document the malfunction during this visit. 3. May 1, 2023: A second visit to the dealership was made for the same problem, but the malfunction was not resolved and the problem persisted. 4. **September 2024:** Another visit was made to the dealer, since the piston problem remains unresolved and the dealer has not yet addressed or adequately documented the malfunction. In all previous visits it is documented by the concessionaire that at the time of the test it did not present condition. 5. **Current status (to date):** The problem remains unresolved and we have continued to be without a vehicle every time the unit is taken to the warranty area. The amount of time that the vehicle is in the workshop is indefinite and at no time has we been offered a vehicle similar to a loaner as established by regulations #19 and #21 of the Department of Consumer Affairs (DACO). Despite multiple attempts to solve the problem, the dealer has not repaired the vehicle and the problem continues. This last time we have been without a vehicle for the whole month of September 2024. This represents a chronic anguish for our family, since we depend on our vehicle to be able to work in our accounting business. In addition to all this, this problem with the unit has created an insecurity in us, since at any time it can leave us without service; we have the responsibility to pick up and leave our grandchildr INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA),

Engine Mounts are faulty / victim of design fault. I have had my engine mounts replaced twice within the first 7,000 miles of ownership (at 3,825 miles and again at 6,583 miles). Per my service advisor this is a common issue with all Grand Cherokee models and he anticipates the need to replace them again.

The vehicle will run extremely rough and not accelerate when needed especially after filling the tank with gasoline. It will almost die in the intersection when you’re trying to get past Traffic. It will not reach Highway speed at times and when you step on the gas the engine makes a strange noise and it slows down. The vehicle is very dangerous in this regard. One time I almost had an accident because of it. I have had the vehicle to the Jeep dealership at least six times for this issue and they cannot confirm that it happens on their own and they cannot fix it. I have video evidence of this problem taking place over many months. Chrysler and jeep will not help me. I am concerned about the welfare of the public if they are driving a similar vehicle.

On 7/9/24 I was driving on the highway and jeep began to lose power and speed. I was unable to accelerate to maintain speed or safely pull to the shoulder. Jeep completely lost power and stopped in the middle of the highway and I had to wait with hazards until I could successfully turn on the car and drive again. This exact thing happened again today on 7/16/24 it was very dangerous and scary especially since I was almost rear ended.

The vehicle makes a metal like grinding noise when stoping and shutting off the engine. has had numerous problems where multiple warnings lights will appear on the instrument cluster followed by the vehicle losing power steering and the ability to be controlled. The radio screen with black out and functions will be rendered unusable through the radio, intermediately. The vehicle displays active error codes to include loss of communication with body control module. The vehicle will crank and drive off without a key fob present in the vehicle. The vehicles engine is making a loud knocking noise. The vehicle has been to three different dealerships and has been unable to be fixed despite several hard resets/updates/“flashes” and a power steering assembly replacement.

Yes I got this in sept 2023 it’s had 3 recall sense then and now it’s got be back in shop for 3 days for valves bad and can mess engine up I’m paying too much money to keep having issues

When starting and stopping the engine an awful noise is heard, it sounds like metal is grinding for about 2 seconds. Also on one occasion the electrical system seems to go haywire, as my power lift gate would not work. I tried several things to include turning the vehicle on and off, pressing the lift gate button several times, pressing my clicker, and pressing the lift gate button in the cabin area of the vehicle, to no avail. I finally had to pull the lift gate down, while this was occuring the inside the vehicle on the lift gate lights would turn on and off it was the strangest thing.

I was driving on a major interstate and my car suddenly stopped shifting the gears to allow for faster speed. RPM's were going up to 6 and 7 and the fastest I could go was 30mph. I confirmed my vehicle was only in Drive, and was not in a "sport mode that allows for manua shifting". Was able to safely get off the interstate and pull over, This could have caused a accident. Shut down vehicle and restarted and then performed correctly. Called dealership and they stated they wouldn't be able to get me in for 3 weeks and if the vehicle is now not doing it and issue can not be duplicated there wouldn't be anything they can do.

Dashboard showed Transmission Error Message: Service Transmission Continue in D, Do Not Shift or Turn off Engine Until you Reach a Desired Location, You may not be able to shift again until serviced. Vehicle was stuck in 1st gear and would not shift out for 5 minutes. Taken to dealer with engine light on and shown pictures of error messages and dealer found nothing wrong with vehicle. This all happened on a highway and I had to navigate from high speeds to slow and stop in the exit lane.

My vehicle was stopped for several minutes on an upgrade, with stopped cars in front of me due to a traffic jam. I needed to keep pressure on the brake, lest my car roll backwards. After about three minutes, brake pedal lost pressure and my foot went to floor. The engine then went into gear and my car rammed car in front. Engine stalled on impact and was hard to restart. Vehicle currently at Jeep dealer awaiting inspection from Stellantis tech team. This situation reported to their customer care center. No warning lights appeared on dash prior to crash. Indeed, this could have been a more serious accident. I will never trust this vehicle again, and intend to take steps to exit my lease.

On 10/07/2023, about 7:30 pm, I was driving down 6th Street in Beaumont California at about 30 mph speed when all of a sudden the engine made a horrible loud noise and it looked like the accelerator pedal was suddenly hit. It seemed that the vehicle speed did not increase accordingly, but my foot had released the gas pedal already. Once I confirmed that the noise was indeed coming from my car, I pulled over and turned off the engine while the loud noise was continuing. Then I restarted the car and the problem didn't reoccur this time. Then, the car has performed normally.

We have been without service of the Grand Cherokee L vehicle for nearly 6 of the 11 weeks since we leased the vehicle. The four (4) incidents and ‘repair attempts’ to ‘fix’ the randomly/sudden occurring mechanical and electrical problems were inter-related and causal to the mechanical and electrical blackout troubles. 1.02/27/23 Purchase 2.03/20/23 631 total miles traveled. Dash board blackout. a.Service Dept “reset software”. 3.03/31/23 912 total miles traveled. Complete dashboard, radio and navigation blackout a.Service Dept did not experience random failures, “therefore no repair action was warranted”. 4.04/01/23 930 total miles traveled. While traveling at approximately 45 mph vehicle suddenly seemed to drop gears - the rpm went from 2k up to 6k, the suddenness of the drop of gears had our seat belts tightening. pulled the car to the side of the round and car remained at 6k rpm. I turned the car off, waited a few seconds then restarted the vehicle and proceed home. 5.04/02/23 after starting the car remotely car literally would not get out of automated start mode. I had to turn the vehicle off, wait a couple of minutes before it would start again. In driving the vehicle to the repair shop the power went out of the radio/gps/etc system again. a.Service Dept found RADIO with internal failure. Ordered replacement radio.” b.On inquiry, Service stated the CAM bus (software version ‘AG’ was replaced with updated ‘AI’ version.) 6.04/26/23 1,051 total miles traveled. On exiting a parking lot, I tried to accelerate into traffic, the RPM increased but with zero forward motion. I pressed the accelerator to the floor, the RPM increased but zero forward motion. I then released the accelerator, the RPM correspondingly decreased - still no forward motion. Then reapplying pressure - slowly to the accelerator - the vehicle began to roll forward but at an EXAGGERATED slow pace. I slowly rolled across the traffic lane and forward "running rough".

While stopped at the light with your foot on the brake, the vehicle will accidentally accelerate and almost hit the car in front of you. I looked (my foot was still on the brake). Then, when I try to accelerate, this vehicle fails to get up and go... it's like it's stuck in first or second gear... I avoid the freeway because I'm afraid someone will hit me in the rear end! very dangerous.

I took delivery of the vehicle on February 15, 2023. On May 23, 2023 I was driving 35 MPH and without warning, I lost power steering and the brakes (felt like bricks when I tried to stop the vehicle). The vehicle never slowed and continued at 35 MPH. I had to swerve to not hit other vehicles as I was going through stop lights. I put the car in neutral and it slowed down and then put in park.after about 3-4 attempts of turning off/on, the steering started to work as did the brakes. I drove the .5 mi down the street with my hazard lights on back to my house. At that point the engine light remained on. The dashboard lit up with numerous alerts (I made sure to take pictures of everything). I called a tow truck and sent pictures to the dealership. They had the car for 2 days, called and said that they cannot duplicate the issue, despite receiving and reviewing the pictures I sent. They said no other option but to pick up the vehicle or let the service tech drive the vehicle overnight to see if the issue could be duplicated.

The contact owns a 2023 Jeep Grand Cherokee. The contact stated that while driving at an undisclosed speed, the check engine warning light illuminated. The vehicle was taken to the dealer where the ECM was reset; however, while driving the failure recurred and the vehicle stalled. The vehicle was towed to the dealer. The dealer was unable to duplicate the failure. The manufacturer was not made aware of the failure. The failure mileage was 197.

Mileage: 197
