2022 Jeep Grand Cherokee electrical system problems

“[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…”

“My vehicle has multiple software and electrical issues that Jeep has been unable to diagnose or repair, and there is currently no recall addressing these problems. One of the most serious issues is that the vehicle will randomly switch the display language from English to Italian while I am driving. When this happens, the speedometer changes from miles per hour (MPH) to kilometers per hour (KPH), making it difficult to know my speed without pulling over and manually changing the language back to English. This creates an unnecessary safety concern. Additionally, the automatic door lock feature no longer functions properly. Although the dealership has repaired it in the past, the problem has returned. I also continue to receive a dashboard warning indicating that the Forward Collision Warning system is disabled, even though the feature is clearly enabled in the vehicle's settings. This inconsistency raises concerns about whether the safety system is functioning as intended. Another ongoing issue is that the vehicle randomly drains its battery. Both AutoZone and the dealership have tested the main battery and the auxiliary battery, and both have been found to be…”

“The contact owns a 2022 Jeep Grand Cherokee. The contact stated that while driving approximately 35 MPH, the lights on the instrument panel became dark and the vehicle stalled. The failure had occurred on several occasions. The vehicle was taken back to the residence; however, the vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 20,000.”

“The 12-volt auxiliary battery on this 2022 Jeep Grand Cherokee 4xe plug-in hybrid repeatedly discharges to a completely dead state while the vehicle is parked and switched off. The vehicle has failed three times in approximately 30 days. First failure, June 26, 2026: the vehicle would not start. Numerous fault codes were stored across multiple modules, including P0562 (system voltage low). The odometer display was flashing, indicating a module had dropped off the communication bus. Second failure, July 13, 2026: less than 48 hours after returning from a road trip and parking, the same condition recurred. The vehicle required external 12-volt power to start. Third failure, July 26, 2026: a brand-new AGM battery had been installed on July 24, 2026. Within 48 hours of installation the battery measured 5.85 volts — fully discharged. An 80Ah battery discharging in 48 hours indicates a continuous parasitic draw of roughly one amp, which is 20 to 40 times the normal key-off draw for a sleeping vehicle. Owner testing has ruled out both the battery and the charging system. The DC-DC converter was measured delivering 127 amps at 13.9 volts, confirming it functions. The…”

“Unknown On XXX, our 2022 Certified Pre-Owned Jeep Cherokee Hybrid was brought to the West Plains location for a factory safety recall or recalls and the check engine light on. During the software installation, the technician improperly executed the procedure, took the Integrated Dual Charger Module (IDCM) offline, and completely disabled the vehicle. The West Plains Repair Order explicitly states: "Caused by codes for IDCM and module offline, will not come back online, and has disabled vehicle." Because the vehicle was rendered completely undriveable, it had to be flatbed-towed 90 miles to James River Jeep in [XXX] to resolve the corrupted modules. The Ozark service department confirmed the vehicle arrived disabled due to West Plains' improper procedure and required a new battery to restore system diagnostics. The West Plains General Manager, [XXX], flatly refused to cover the resulting $1,100+ invoice for the battery ($638.71) and towing fees. Mr. [XXX] used intimidating tactics, completely dismissed our concerns, and claimed his dealership 'chooses not to work on hybrid batteries' to evade financial responsibility. This claim is demonstrably false; on October…”
