Filed Oct 31, 2026 · Engine, Fuel system · NC

Hybrid engine failure. Jeep vehicle is unsafe to drive as the electric engine doesn’t work due to overheating and charging error codes, which causes power to jump between electric and gas engine spontaneously causing speed control to be unpredictable and unsafe. There is also the question that there is a serious defect with the battery and unsafe to park this vehicle in a garage attached to a dwelling unit.

Awaiting motor mounts. Causative water pump replacement. Loose feeling and creaking sound when operating the vehicle. Hard knocking sound when shifting gears to drive or reverse. I thought most of all of the sounds were normal because it is a Jeep. This has been for more than I realized.

[Incident Description & System Failure] On XXX, at approximately 30,340 miles, hybrid propulsion and charging system completely failed while the vehicle was in motion. The vehicle suffered a sudden "Loss of Motive Power" and stalled completely on a public road. The vehicle was towed immediately and is currently inspection upon request. [Safety Risks Experienced] The vehicle suffered a catastrophic power failure and stalled suddenly in the middle of a public road. This created an immediate hazard for a severe rear-end collision. Furthermore, according to the manufacturer's official Safety Recall 68C (the federal safety agency 25V‑741), this specific battery pack poses an unmitigated vehicle fire risk, threatened by both traffic hazards and potential thermal runaway. [Dealer Confirmation & Inspection Status] The defect has been officially reproduced, confirmed, and documented by an authorized dealer. Following the sudden stall, the vehicle was towed to McPeeks CDJR of [XXX] on XXX (Repair Order #XXX). The service advisor and technicians confirmed the failure, noting the active check engine light and red battery light. The vehicle is currently under inspection and storage at the dealership, as the manufacturer's technicians have been unable to remedy this recurring. [Prior Warning Lamps, Messages & Symptoms] At the same time the engine stalled on XXX, the dashboard illuminated a red battery warning light and a check engine light, by a system message: "Service Charging System. The vehicle had a long history of chronic hybrid system symptoms and was previously brought to the dealer for multiple official safety recalls regarding the high-voltage battery (95B in Dec 2024, 73C in XXX, and 68C in XXX). The manufacturer issued a Warranty Extension Letter (Program XU1) for this defective battery pack. Despite all prior software flashes and recall "remedies" performed by the dealer, the system completely failed, proving the defect is incurable.

​Vehicle Information: ​Year / Make / Model: 2022 Jeep Grand Cherokee Overland 4xe ​Component(s) Involved: Engine / Hybrid Powertrain / Electrical System / Sudden Loss of Drive Power ​Current Mileage: Approximately 48,000mi ​Incident Summary ​I am filing this complaint because my 2022 Jeep Grand Cherokee Overland 4xe has developed a dangerous new defect following an official recall service: the engine completely dies while accelerating on the highway. ​I took my Jeep to an authorized dealership to have the safety recall performed for the engine shutdown issue. Before this recall work was completed, I had never experienced the vehicle dying on the highway. Since the recall "fix," however, the engine has cut out completely 4 separate times while accelerating at high speeds. The most recent time happened today (August 3, 2026). Losing all pedal response and motive power in fast-moving traffic with no warning is terrifying and creates an extreme hazard for myself and everyone around me. ​History of Vehicle Issues & Extended Shop Time ​This sudden highway stalling comes on top of severe, ongoing electrical problems that have plagued this Jeep. Altogether, the vehicle has spent months sitting in the dealership shop, yet the problems remain unfixed: ​Post-Recall Engine Shutdowns: 4 separate complete power loss incidents while accelerating on the highway (latest occurrence: August 3, 2026). ​Unresolved Battery Drain: Ongoing parasitic battery drain that kills the battery, requiring multiple rounds of diagnostics without a solution. ​Pervasive Electrical Glitches: Frequent system glitches, including frozen touchscreens, instrument cluster reboots, random dash warning lights, and connectivity drops. ​Media Hub Issues: Hardware problems involving the media hub module. ​Requested Action ​The recall fix did not solve the safety hazard—it seems to have triggered a new, life-threatening stalling issue on the highway, along with the string of other issues, it's unsafe to drive.

I am submitting this complaint regarding a serious safety-related failure involving my 2022 Jeep Grand Cherokee 4xe. I purchased the vehicle used with approximately 15,000 miles and was informed the previous owners leased it and rarely used it. At approximately 40,000 miles, despite completing all recalls in a timely manner, the vehicle experienced the exact type of hybrid system failure a recall was intended to prevent. The issue began when the hybrid system failed and left the vehicle unsafe to operate. Upon startup, only accessory power activated and the engine would not start. A full power cycle was required before the vehicle started. Immediately afterward, warnings appeared including "Service Hybrid System," "Service Charging System," "EAB Unavailable," "Lane Keep Assist Unavailable," "Pedestrian Braking Unavailable," and "Adaptive Cruise Control Unavailable." The check engine light illuminated and all hybrid modes became unavailable. Shifting became erratic and harsh. Downshifts from 2nd to 1st felt like sudden braking and caused me to hit my head on the steering wheel. During acceleration, the transmission slipped and shifted unpredictably. Fuel economy dropped from approximately 22 MPG in E-Save mode to approximately 10 MPG at highway speeds. Diagnostic code P1E1D was retrieved and I was advised the vehicle was unsafe to drive. While driving to the dealership, the vehicle shut down twice while in motion. During both shutdowns, power steering and braking assistance were lost, posing an extreme risk to myself and others while moving the vehicle off a busy three-lane roadway. Dealership diagnostics determined one or both high-voltage battery systems failed and required replacement. Despite completed recalls, the issue still occurred. Parts were backordered over a month. I believe this failure and recall effectiveness warrant investigation due to the serious safety risks created by loss of propulsion, steering, and braking assistance while driving.

I, [XXX] was driving home from work on Friday, May 1st on [XXX] in [XXX] during heavy traffic when my vehicle suddenly shut off while traveling approximately 65–70 mph. I initially thought I may not have been pressing the accelerator hard enough, but the vehicle would not respond at all. I then looked at the dashboard and saw a message that said “push brake to start.” At that moment I realized the vehicle had shut down completely while I was in active traffic. I had to coast across three lanes of traffic without any propulsion to reach the shoulder. During this time, I was nearly struck twice from behind because I could not maintain speed with surrounding traffic. Once I reached the shoulder, I was able to restart the vehicle. I was extremely shaken and frightened by the incident. I do not feel safe driving this vehicle again. I was very aware that I could have been seriously injured or killed, and I am thankful I was not struck. I am especially concerned about what could have happened if my grandchild had been in the vehicle with me. This incident occurred after a recall repair had already been performed in September 2025 related to powertrain/hybrid system issues. The failure appears to be the same or similar to the condition the recall was intended to correct. After restarting the vehicle, I drove cautiously to my husband’s workplace and left the vehicle parked. Since the incident, I have experienced ongoing anxiety and distress reliving what happened. This vehicle was intended to be a long-term purchase, and it is extremely concerning that it now appears unsafe to operate. This event represents a serious safety hazard. A sudden loss of propulsion at highway speeds without warning creates a high risk of crash, injury, or death. I am requesting that this issue be investigated, as the prior recall repair does not appear to have corrected the problem. I do not feel this vehicle is safe to operate.

I am a former Transmission Calibration Engineer at Stellantis, so I know what I'm talking about. I experienced an engine stall event while coasting down in speed. I was in town, driving about 30 mph, and coasting (0% pedal). I lightly applied the brakes and while the vehicle was still in motion (coasting) the engine stalled. The information cluster displayed a message that said "put the vehicle in park and restart the engine." I coasted around a corner, came to a stop, put the transmission in Park, and restarted the engine. No MIL or codes were set. I have a scan tool and confirmed later that no codes were set. I'm fairly certain the engine was in DFSO (decel fuel shutoff) when the issue occurred as the conditions were all correct for DFSO (engine was in normal operating temperature range, gear was 5th or 6th when coasting was initiated, and pedal was 0% for several seconds before the issue occurred). Loss of propulsion is an obvious safety concern as I lost control of the vehicle.

The vehicle experienced a hybrid system/charging failure documented by the servicing dealership as “service hybrid system message and vehicle will not charge.” The vehicle also had battery-related failure requiring a jump and repeated service visits. This caused loss of use and raised reliability and safety concerns.

This is the third time that my jeep has completely shut off with no warning and in the middle of traffic. I am unable to turn on any hazard lights. The power goes completely out, and I am unable to put the car in neutral or anything to be safe. I have reported this issue in the past. The dealership is unable to figure out what is wrong and I keep trying to get this resolved before it turns out tragically. Please help me before I loss my life in this vehicle.
