2022 JEEP GRAND CHEROKEE Power Train Problems

The vehicle has experienced recurring safety-related issues associated with the hybrid electrical and propulsion systems. During normal operation, warning messages related to the hybrid system appeared, and the vehicle entered reduced functionality or became unreliable to operate. These conditions created concern about potential loss of propulsion while driving. In addition to propulsion concerns, the vehicle was subject to manufacturer recalls related to the high-voltage battery system, including warnings regarding battery overheating and potential fire risk. Recall-related service was performed by an authorized dealer; however, safety concerns persisted after service was completed, and confidence in the safe operation of the vehicle was not restored. The ongoing nature of the electrical and hybrid system issues, combined with recall notices involving battery fire risk, created a safety concern for continued use of the vehicle, particularly due to the possibility of vehicle malfunction or battery-related hazards during normal operation or while parked. No crash or injury occurred, but the condition raised ongoing safety concerns. The issue has occurred more than once and was not permanently resolved despite dealer inspection and recall-related service.

Screens switches to Italian, also screens freeze or go blank, Front Collision Warning (FCW) light illuminates and can't be turned off. Bluetooth randomly disconnects, Auto door locks don't engage; paddle shifters for manual gear selection cease functioning, pedestrian avoidance, automatic emergency braking, and high-beam assist stop working; memory seats unexpectedly adjust while driving. I have to bring the car to the dealer to fix this, this happens every 14 days or so.

The vehicle losses propulsion. The EV battery drains rapidly. Electronics and hazards will not turn off at times. The head unit screen and user interface is unstable and in consist. Instrument cluster provides has had previous failures.

Driving home and car had a sudden loss of power randomly while driving. It would not restart until 5-10 minutes later despite multiple start/stop attempts. On the screen it stated to “plug in to condition battery.” We were in the left lane on a busy road with construction and were almost rear ended multiple times while car was not functional. Have had multiple issues with battery on this 4xe - did recent software update at dealer. I have taken it to dealer previously for battery code (service battery) and they stated they can see code, but unsure of what problem is. No warning lights prior to incident. It sounds like through reviewing on internet this is a common problem with 4xe vehicles and if it hasn’t killed someone yet, it certainly will. We did call 911 for assistance due to the vehicle being disabled in middle of highway, but no official report was made.

Timing cover leak, replaced by dealer once covered under warranty. Few months later same leak occurred in the same park after dealer replacement. Back to the dealer to have checked, dealer found that the head gasket during manufacture/casting has defect causing the head gasket to protrude into the mounting surface for the timing cover gasket/seal causing improper seal and securement. Dealer got Jeep engineers involved and found it was during manufacture and assembly/casting process. New head gasket being replaced and installed inspection of all mounting surfaces on cylinders valves and pistons for additional damage, and replacing timing cover gasket again. This caused loss of engine oil over time even after dealer fix and replacement the first time, this could cause drivers to not know they are low on engine oil causing potential catastrophic engine damage or failure/seizing during normal operating conditions. This is a common failure in the Jeep 4xe of timing cover seal issues and leaks.

The car will cut off and loose power due to the battery issue It has been in the shop 5 or 6 times for this issue and some of the stays were over 30 days at a time They said they have no fix for the repair needed not to drive it but no one can make payments on a car and not drive it for months waiting on a repair. They refused to buy the car back or replace it with a new one.

After dealer installed recall 24V-720 on 1/15/2025, I started seeing Red Wrench light and warning to Service Hybrid System a few times each month. The warnings only flashed for a few seconds and disappeared - no service engine light. Also, the vehicle failed to charge about half the time. In early May, I was driving (in hybrid mode) about 45 miles per hour, and the Red Wrench light and warning to Service Hybrid System flashed and disappeared. The car would NOT accelerate! I DRIFTED to a safe spot, turned off the car, and restarted and now could accelerate. I was lucky! I brought the vehicle to Jeep on May 19, 2025. It was there for about 10 days and they found nothing - not able to reproduce and no errors logged, etc.They created a STAR Case (#1020705742) and still no solution. This is exactly recall 25V-576. The vehicle always charges now even though Jeep says they only cleared other errors. I brought the vehicle to Jeep on September 10 and they didn't see any saved errors. NO updates to STAR Case. I continue to see the Red Wrench light and warning to Service Hybrid System every week or so. But, have only lost power once. I'm afraid to drive the vehicle - always looking for a place to safely stop. How can a vehicle lose power and not log a Service Engine error! I need a FIX! I looked at selling the vehicle but it has lost a lot of value likely due to all the recalls. I believe the battery has issues and should be replaced. Recall 24V-720 only installed software to watch the battery. However, nothing is ever logged.

On September 10th, 2025, at approximately 7:45am, I was driving my 2022 Jeep Grand Cherokee 4xe at 57 mph on the freeway during heavy traffic. The “Service Hybrid Electrical System” warning appeared, and the vehicle immediately stalled and forced itself into emergency park while in motion. This sudden failure created a severe safety hazard for myself and surrounding drivers. I experienced an anxiety attack from the incident and had to call my husband for help. This is not the first time the vehicle has stalled, but it is the most dangerous occurrence to date. This vehicle is unsafe and poses a life-threatening risk on public roads.

Driving and engine shut off in the middle of the road. Vehicle indicated “service hybrid system.” Was able to restart vehicle after a few minutes.

I am a victim of SUA (sudden unintended acceleration. I entered my driveway and had my foot on the brake petal. Before I could shift into Park, the vehicle revved to a high RPM and then took off like a rocket. Brakes were initially hard to press and then the petal went to the floor, and I lost the brakes. This all happened very quickly and took me by surprise. I crashed through a double cyclone gate, closed garage door, back of the garage, double fence in back of garage, neighbors jacuzie and shed, hit the side of another neighbor's house and AC unit. It seemed that the power train electronics malfunctioned and caused all of this. Progressive insurance took procession of the vehicle and declared it a total loss.

While driving on the freeway, the vehicle suddenly lost all power and control. The “Service Hybrid System” warning began flashing, and I experienced a complete powertrain failure. As the vehicle coasted down to under 5 mph, it abruptly slammed into the electronic parking brake and came to a hard stop. This created a serious safety hazard not only for me but for other drivers on the road. The vehicle had to be towed to the dealership, where it required a jump-start to regain power. The dealer has been unable to replicate the issue, and no diagnostic trouble codes were found during their scan. Despite this, the failure was severe and unpredictable. There were no warning lights or symptoms prior to the event. The vehicle is currently at the dealership and available for inspection.

Multiple warnings with the service hybrid system alert coming on the dash. Code B273C-00 was confirmed by the technician at the Napleton Jeep service department. Vehicle can shut off at any time at any speed and there is no resolution at this time to fix the issue. When accelerating over uneven surfaces, the vehicle bucks back and forth violently. This concern was verified with the technician at Napleton Jeep. The shop Foreman contacted Chrysler zone engineering and confirmed that they are aware of this issue but there is no current resolution for this issue. This is highly dangerous when pulling out into traffic.

On three different occasions, the Jeep randomly turned off on its own. Each time I was stopped, so thankfully I was not injured. I brought it to two different dealerships, one in May 2025 and one in July 2025, and neither of them could fix it. The last dealership advised me not to drive the vehicle due to the safety implications of a stall during driving due to "the digital crash input issue". As a result, I sold my Jeep and bought another vehicle. The vehicle was still under warranty when I sold it.

Car has a defective hybrid battery that is unrepairable by manufacturer and the vehicle will turn off while driving

While driving in Hybrid mode, the Jeep threw itself into park. I was at the middle of an intersection. I put it back in drive, then it did it again once I started moving. 1. The hybrid mode threw the car into park while moving. 2. This happened to me a few times in a row, but once in the middle of a major intersection. I was lucky there were no cars that crashed into me. 3. I have brought this into Chrysler, Jeep, Doge of Paulding (Georgia) and they have reached out to the engineers at Chrysler. The service department is telling me that Chrysler is telling them there is no fix to this. I put in a ticket with Chrysler as well and they confirmed this. My ticket number is 93581933 4. the vehicle has only been inspected by the service department at the dealership. 5. I did get a hybrid engine maintenance light one time when it went into park. But not each time it did it.

Within days after completing the 95b recall (24v-720) on my Grand Cherokee 4xe PHEV , the vehicle would periodically flash an error message saying ”service hybrid system” or something to that effect. It would illuminate for just a few seconds. On May 21, I took the vehicle back to the dealership (Brigham-Gill, Natick, MA). They read several codes and after conferring with Jeep, said the vehicle is unsafe to drive. It has remained there parked in their backlot as of July 15. The dealership is awaiting guidance from Jeep and informed me they have several others in the same situation. So there were few issues here 1) if I hadn’t returned to the dealership to ask about these brief flashing messages, I would not have known that the vehicle was unsafe to drive. These messages never stayed illuminated for more than a few seconds, and there is no residual “check engine” light. 2) it is incorrect to say that the 95B recall addressed the issue of the failing batteries if it renders the vehicle in operable. 3) the 95B recall patch software was released in January 2025. I find it hard to believe that as of mid July they’ve been unable to find out why it doesn’t work in all the vehicles as intended. This leads me to question the thoroughness of the regression testing before it was released.

The contact owns a 2022 Jeep Grand Cherokee. The contact stated while driving at an undisclosed speed, several unknown warning lights illuminated. The contact stated that the unknown warning lights indicated powertrain failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact stated that the vehicle had been scheduled for an upcoming diagnostic test. The manufacturer was made aware of the failure and a case was filed. The failure mileage was approximately 50,089.

Mileage: 50,089

The red wrench light keeps coming on, Hybrid system needs repair. It looses power for a short period of time, every time has been on the freeway. It makes a hugh crunch noise(transmission) and slams into gear. It is available for inspection, currently at dealership, it has been there for last week. This problem has been persistent, its been in many times for this issue. Chrysler told me they do not have a fix. It is all over the chat forums. We do not feel safe driving this car because it looses power temporarily and on the freeway. Many others are having problems with it stopping from a loss of power. It has been inspected by the dealership and in for repairs many times. This vehicle has been in the dealership on a regular basis since it was new. It has always had a power train issue, clunky and loss of power. Now it is worse and they don't have a repair. It has also had engine lights coming on and off. Had issue with having to put it in park turn off and turn back on to get it in gear. The loss of power on the freeway is the persistent issue right now. These cars need pulled off the roads until they are fixed!

Vehicle suffers from a documented hybrid defect (DTC B273C-00) that causes loss of electric propulsion, disables hybrid modes, and triggers "Service Hybrid Electric Vehicle System" warnings. The problem first appeared around Feb 2025 and was confirmed by FCA’s own STAR bulletins and dealership diagnostics. No validated fix exists; dealership only cleared the fault code temporarily. The defect led to: • Power loss during highway merge on [XXX], with children in the car • Sudden unintended acceleration on [XXX] • Persistent warnings and failure to operate in advertised hybrid/electric modes for over 120+ days FCA refused to repurchase, replace, or permanently repair, despite acknowledging the defect and safety risk in internal documents. The vehicle remains in ICE-only mode, depriving it of the key safety and efficiency features it was designed to provide. The defect significantly raises risk of collision due to unpredictable propulsion response, and no dealership or FCA representative provided written certification the vehicle is safe in all drive modes. Vehicle purchased in Wisconsin but always registered and operated exclusively in Illinois. Arbitration through NCDS confirmed the defect exists but denied relief, citing insufficient corroboration. Problem was reproduced and confirmed by certified dealership and documented in service records. This complaint is part of an ongoing concern that hybrid system EMI issues (like DTC B273C-00) pose systemic safety risk and remain unresolved.

Driving vehicle and it lost all power. Warning light for Service PHEV came on solid on dash. Switched to ESave and was able to drive approx 2 blocks and vehicle lost power again in middle of road. Shifted to neutral, restarted and was able to side of road. Called tow company to deliver to dealer. Side note- vehicle was in dealer on 6/30 with flashing Service PHEV light; dealer ran code and returned with DTC of B273C-00 (Digital Crash Input). Dealer stated that vehicle is going into a “limp mode” due to 95B software update, and that there is not a fix, and other vehicles are at dealership unable to repair. When asked for advice what I should do, the response was “ do not take a long road trip”. I drove approx 60 miles since and the vehicle went into solid limp mode. Being evaluated at dealership currently.

In January work related to recall 95B was performed on the Jeep. The next day the issues started with a warning light indicating the Hybrid System needed service. The Jeep has been in repair for this issue 6 times and over 56 days with no resolution. It is currently in for repair. A buy back request was made but both FCA and the arbitrators indicate it is not a safety concern. There are safety concerns related to the Warning light as it appears to impact electrical communications in the vehicle. Repair notes indicate the communication issues. Also, power steering has stopped working and the engine has died while driving causing a rapid deceleration. Multiple users are reporting the same issues or additional impact related to the Hybrid warning light that started after 95B work.

Last week I was driving 70MPH on the highway when suddenly I got the red wrench icon with the message "Service Hybrid Electrical System" on the dashboard. After about 7 seconds I then got a "Put foot on brake and press start" message on the screen - while still going 70MPH on the highway. At that point the car died. I had no power - the accelerator pedal did nothing. Luckily, I was able to pull over to the shoulder and stop. Then I did what it said and pressed the brake + start button. The car came back to life, but I didn't have the full hybrid system - I only had gas - the car was not using any electrical power as the battery level remained constant and did not drop as I drove. I continued for another 20 minutes where I stopped for lunch. When I returned to the car it started up normally and continued to run normally after that. This is the 3rd of 4th time the red wrench icon with the Service Hybrid system warning coming up, but on the previous times the message went away after about 5 seconds and the car drove normally. This is the only time that it caused the car to completely die on my while on the highway. Apparently, this has been happening to a *lot* of people after Jeep issued a software update to address the 95b recall last year. Many owners are now afraid to drive their Jeep 4xe for fear of it suddenly dying on the highway at high speeds.

What component or system failed or malfunctioned, and is it available for inspection upon request? When driving down a busy road, the car completely stalled with loss of power steering, unable to accelerate or brake, power completely lost in car with all safety lights illuminated on the dashboard. Eventually brakes returned, able to stop car. Unable to restart and loss of power for windows. After several attempts, restarted car with warning lights still present- moved to side of Road. Currently at dealer for inspection- stated that problem was "digital crash input code failure" and that there is not a fix for this at this time. How was your safety or the safety of others put at risk? Car stalled with complete loss of control in the middle of traffic, while accelerating at approximately 15-25 mph. This could have caused an accident, but luckily did not. However, car was stalled in traffic for about 30 mins and unable to move car at all- blocking traffic on busy street. If happened on highway, could have been much worse and also had the potential to cause an accident. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem was confirmed by dealer, and said that there is "no fix". According to them, all recalls have been fixed in this vehicle prior to incident and should have fixed this problem by replacing the battery. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Vehicle has been inspected by both dealership service and Chrysler/ Stellantis engineers. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? There was 1 warning light message about "EV system hybrid control" needs service, but disappeared after 30 seconds and this appeared about 1 week prior to incident.

My car was showing a "service hybrid system" warning light in the months of April and May 2025 intermittantly along with a slight loss of power. I took it to the dealership and was told its a software issue but it's fine. Stellantis is aware of this issue but there is no fix. I brought it back a week later with the same concerns and reading the document the dealership gave me - the 95B recall fix apparently crashed communication modules with my ORC. I expressed safety concerns. The dealership once again cleared codes and told me it was safe to drive. One week later on May 8, 2025, I was driving home from work. Without warning, the car locked up and went limp in the middle of the road. I went from 35mph to 0mph without seconds. I luckily was not rear ended. The dealership opened up another case with STAR. I have since gotten rid of the car due to continuous recalls and issues. I did not feel safe in this car and I feared for myself as well as others on the road. I am only taking the time to report this because there is no fix, my dealership repeadily gave the car back to me (in the notes, it was to be returned to me on 5/12 with no fix), and others are having the same issue.

While the vehicle is in operation, and without warning, it loses all motive power and coasts to a stop. A warning message is displayed on dash: “Service Hybrid Electric Vehicle System.” The vehicle must be turned off then back on before motive power is restored. This is an extreme safety issue, if it were to occur at highway speeds amidst traffic, the likelihood of serious accident is high. Jeep dealer service says this is a known issue with many Jeep 4xe vehicles right now and no fix is known. This event has reoccurred more than 4 times. The most recent was 5/9/25.

Once a week or so, the vehicle will experience motive power loss while driving. Typically, it's for 3 or 4 seconds and is accompanied by a blinking red "Service Hybrid Electric Vehicle System" warning light on the dashboard. This is very dangerous because for those 3 or 4 seconds, the vehicle will not accelerate/maintain speed. I've had the vehicle at the dealership for the same reason multiple times. The dealership has tried to identify the root cause but so far has not been successful.

I've had issues with this jeep grand cherokee 4xe randomly shutting down on the highway at speeds between 65-75 mph. The service engine and transmission lights come on and the vehicle itself dies out and will power on but will not start for about 10-15 minutes afterwards. This is the fourth time I've had the issue and the dealership can not pin point a reason/fix for the car suddenly stopping. This last time the power steering went out as well these issues have almost caused several accidents . The dealership just clears the codes after saying the can not replicate the problems I'm having and gives the car back. I've gotten to the point now after almost being rear ended trying to clear the vehicle that I no longer feel safe driving it not only for myself but the other drivers around me a car with a little over 20,000 miles should not be having these issues consistently.

We opened a warranty service case #92312434 yesterdday because case #91655707 was closed prematurely while our vehicle is still in disrepair. Our 2022 Grand Cherokee has been to Lithia Jeep of Reno for warranty service on seven occasions since October 29th, spanning 89 days, for a vibration issue which remains unresolved as of today. The manufacturer is in material breach of 49 U.S. Code § 30120 and refuses to offer a replacement or repurchase despite prima facie evidence of failure to repair within a reasonable time (defined as 60 days).

Bought vehicle from Joe Machens Chrysler, Columbia, MO. [XXX]. The net day after a long drive out of town, the owner put vehicle in reverse to leave home and there was an issue. The vehicle sounded like it had “run over a metal garbage can.” It vibrated the floorboard as well. It happens only when the car is in reverse. It happens immediately when you try to back up. It is available for inspection on request. Safety is not an issue, the dealer could not reproduce the sound (owner left vehicle at dealer overnight. It was only inspected by the car dealer. There were no warning signs. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Two problems: 1- this happened twice, after shutting and exiting the vehicle with the key fob, the vehicle goes crazy, lights start flashing, horn honking and the doors auto lock - very dangerous as my child was locked in the car for a few minutes until i was able to play with the key enough to get it to unlock. problem #2 driving vehicle and as coming to slow down it auto shuts off in middle of road, when trying to put it back into gear it says put foot on break and restart the car. it did restart but it is super dangerous as the car behind me could've hit me as it suddenly stopped.
