2022 Jeep Grand Cherokee engine problems

“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 (NHTSA 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…”

“​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…”

“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…”

“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…”
