2022 Jeep Grand Cherokee Powertrain & Transmission Problems

The right PTU has failed out of nowhere causing a very loud pop and then grinding when driven. The vehicle was inspected by the jeep dealership last week to find that that was the issue. There was no warning or symptoms prior to the problem. The safety risk is evident in that it could cause an accident, the vehicle to stop completely, not Transmitting power and or not going into park. All without warning. The replacement is very costly

The vehicle has experienced repeated electrical failures. On multiple occasions the vehicle would not start and lost all electrical power. The main electrical system appears to fail suddenly, causing the vehicle to become inoperable. The vehicle has been to the dealership multiple times for the same issue and was out of service for extended periods. This is a serious safety concern because the vehicle can completely shut down without warning.

On January 23, while driving, the vehicle suddenly shut down and stopped working without warning. I attempted to restart the vehicle several times, but it would not start. Smoke was coming from the engine area, and the vehicle was completely disabled on the road. I was stranded on the roadside until approximately 11:30 PM, waiting for a tow truck to arrive. The vehicle had to be towed and taken to the dealership. The dealership later confirmed that the engine wiring harness had burned and failed. The failed component is currently at the dealership and is available for inspection. This sudden shutdown created a serious safety risk to me and other drivers due to loss of power while driving. The issue was not caused by misuse or modifications. The vehicle has since been inspected by the dealership and a manufacturer (Chrysler) representative.

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.

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.

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.

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.

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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.
