2022 Jeep Grand Cherokee

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.

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.

I am filing a complaint regarding repeated and dangerous safety failures with my 2022 Jeep Grand Cherokee Overland 4xe, which I purchased as a brand-new vehicle on February 22, 2025. The most critical issue is that the vehicle has shut off on two separate occasions—once while in motion driving up a hill and once during a suspension height adjustment while stopped. In both cases, the engine powered down unexpectedly, a red wrench and lightning bolt warning appeared, and the vehicle shifted into park on its own. I was unable to restart the vehicle immediately, creating a severe hazard. These shutdowns were preceded or followed by system warnings including “Electric Mode Unavailable – Service Required,” “Active Driving Assist Unavailable,” “Night Vision Unavailable,” “Traffic Sign Assist Unavailable,” and “Tire Pressure Monitoring Unavailable.” These alerts began appearing within weeks of purchase and have persisted intermittently, sometimes alongside performance issues such as sudden jolts at highway speed. The CDJR dealership in Northern California and various manufacturer (Jeep/Stellantis) technical advisors have inspected the vehicle multiple times. A software defect has been identified and confirmed by Jeep, but no fix is available. A Technical Service Bulletin 08-003-25 dated January 8, 2025—before I purchased the vehicle—acknowledges this issue. Despite this, the vehicle was sold to me, and I was sent home with it multiple times even after reporting these failures. The dealership and manufacturer technical advisors now consider the vehicle unsafe to operate and will not return it until a software update is released. The vehicle is currently at the dealership and available for inspection upon request. Supporting documentation including service records, warning light photos, and communications with Jeep Customer Care and the dealership, can be provided. I urge the agency to investigate this matter due to the confirmed safety risk and lack of timely resolution.

- I received a "service hybrid system" light while driving (it only appeared for a split second and went away) and I took it to the dealership for troubleshooting. The dealership found a stored code of B273C-00. They contacted their Jeep engineers who have not been forthcoming as to what the issue is, but said the vehicle is not safe to drive, so I am not allowed to have the vehicle back (the same dealership has a 2nd Grand Cherokee 4xe with the same issue). Both vehicles are currently at the dealership and should be available for inspection. From my online research it seems to be tied to the vehicle's crash sensor and high voltage cable harness. There are also numerous other owners in online forums discussing the same issue with their Jeeps (Grand Cherokees and Wranglers). -As Jeep engineers are not allowing myself or others to drive their vehicle with this code, they obviously consider it a safety issue. The scary thing to me is, that had I not happen to see that quick flash of the "service hybrid light" I would be driving this unsafe vehicle without knowing it, as it did not turn on the check engine light, so I had no idea there was a stored code until the dealer checked it out. That means there are probably thousands of folks driving around at risk without even know there is a safety issue. -This issue has apparently been going on for months, as the other Jeep at my dealership has there for months now.

On May 4th, 2025, at approximately 10:50am I was traveling at approximately 65mph on a 6 lane highway when the vehicle lost all all propulsion. Following sequence of events took place on car: - Dashboard warning to service hybrid system flashed - Dashboard message to depress break and push button to start car. - Car lost power. Could not accelerate. Display and radio still worked. - Coasted across 2 lanes of traffic to side of the highway. - Car went into Park and Emergency brake engaged without my action. - Pushed start button and car started. On a busy highway, the vehicle would not accelerate resulting putting both my life and the lives of others on that highway at risk. I am now afraid to drive the vehicle. Vehicle has ALL service notice recalls completed. Vehicle taken to Jeep dealer for service. At dealer for 48 hours now. Dealer does not know how to fix vehicle. Dealer stated they have 4 other vehicles with the same exact problem. Dealer stated Jeep does not have a fix. No ETA for fixed car given.

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.
