Owner reports

Selected complaints filed with NHTSA by 2022 Jeep Grand Cherokee owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact owns a 2022 Jeep Grand Cherokee. The contact stated that while driving approximately 20 MPH around a roundabout, the vehicle failed to accelerate as intended while depressing the accelerator pedal before the vehicle stalled. Several unknown warning lights illuminated with an abnormal beeping sound coming from the vehicle. The contact was able to coast to the side of the road. The contact waited for a while and was able to restart the vehicle. The vehicle was taken to the dealer, and the contact was informed that an air bag sensor might have caused the failure. An unknown part was replaced. The contact stated that the message "Service Hybrid Electric System" was continuously displayed on the instrument panel. The vehicle was taken back to the dealer; however, no cause for the failure was found. The vehicle was not repaired. …

- 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). …

Subject: Defective Hybrid System - 2022 Jeep Grand Cherokee 4xe Overland - Sudden Power Loss Vehicle Info: Year/Make/Model: 2022 Jeep Grand Cherokee 4xe Overland VIN: [redacted] Issue: Recurring digital crash input fault ([redacted]) disabling hybrid propulsion. Safety Risk: Sudden propulsion loss while turning or on highway, placing driver and others in danger. Incident Summary: First occurrence: Feb 2025. Latest confirmation: May 2025 (work order on file). Dealership confirmed fault and noted possible ORC module replacement if the code returns. FCA STAR bulletins (S2208000154 & S2408000063) acknowledge the issue but state no official remedy is yet available. FCA refuses to declare vehicle safe in writing. Outcome: Vehicle cannot operate in electric or hybrid mode. This is not a warning light issue - this is a propulsion system failure that compromises basic driving safety. …

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. …

Subject: Supplemental Evidence - ODI Complaint [NHTSA complaint 1663939 and 11673063.] Dear NHTSA, I am submitting supplemental evidence regarding my complaint of loss of propulsion in my 2022 Jeep Grand Cherokee 4xe (VIN ending [redacted] ). On September 4, 2025, Chrysler (FCA US, LLC) filed Recall 25V576 covering 91,787 Jeep Grand Cherokee PHEVs (2022-2026) for the exact defect I reported: a software error in the Hybrid Control Processor that may cause a sudden loss of drive power, increasing the risk of a crash. This defect was documented in my case as DTC B273C-00. My dealership confirmed the code on multiple service visits (February 25, 2025 and May 21, 2025), and the arbitrator in Case #[redacted] also confirmed the defect in his July 7, 2025 decision. …

I am submitting a safety complaint regarding my 2022 Jeep Grand Cherokee 4xe, which experienced a serious mechanical failure on [redacted], at approximately [redacted] CDT in Detroit Lakes, MN. While exiting a ZIPS Car Wash at low speed, my vehicle experienced a sudden and complete loss of power and/or propulsion. I believe the engine shut down without warning, and the vehicle would not respond to throttle input or move forward. I attempted to restart the vehicle, but it remained unresponsive for several seconds. During this time, another vehicle behind me was unable to stop in time and rear-ended my Jeep, causing damage to the rear of the vehicle and my vehicle. …

The vehicle experienced repeated propulsion loss and powertrain malfunction while driving, creating a serious safety risk. This defect has now been formally acknowledged by FCA/Stellantis through NHTSA Recall 25V576 (filed on September 4, 2025). Prior to the recall, I raised these safety concerns through the NCDS arbitration program, but my case was closed despite documentation of the defect. The arbitration program stated the matter was "resolved," even though I had rejected the arbitrator's decision and the case was procedurally closed without binding resolution. After the recall was issued, I requested that my case be reopened under NCDS Rule 20, which allows refiling when new or material evidence is presented. That request was denied, leaving me without a remedy despite the existence of an active recall for the exact defect I had reported. The safety issue remains ongoing. …

The electrical system of this vehicle is causing several issues putting the safety of me, my passengers and drivers around me at risk. Starting at 6,300 miles the vehicle had a temporary loss of power steering. After parking for a day the power steering returned, leading me to believe it was caused by an electrical/software code issue. There was a safety recall for the battery pack starting on fire while parked, driving or charging. No fix was available for quite a while and I could not charge the car or park in the garage. Shortly after having the computer updated to stop it from spontaneously catching fire I have been getting a warning light saying to maintenance the hybrid system, and is accompanied with a momentary loss of propulsion. This happens without warning every 150 miles or so. …

This vehicle is subject to Safety Recall 68C for battery fire risk. The manufacturer issued a directive to park outside away from structures and do not charge the vehicle due to extreme fire risk. Despite having an open case with Jeep, there have been three failed supervisor callbacks with no resolution provided. The remedy is not yet available. The owner refuses to drive this vehicle and refuses to allow his wife to drive it due to serious safety concerns. If the car catches fire while she is driving, there is fear she will not have enough time to protect herself. This is an extremely scary and dangerous situation for the family. Additionally, the owner fears the house could catch fire while sleeping because of this vehicle parked nearby, even following the manufacturer's parking directive. …

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. …
