2022 Jeep Grand Cherokee: battery drain or dead battery

Filed Aug 3, 2026 · Electrical, Engine · IL

​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.

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 in normal working condition. Despite this, the battery drain continues to occur without explanation randomly. These recurring software and electrical problems have become unacceptable. Jeep has been unable to provide a permanent solution, and I believe the company should stand behind its product by acknowledging and resolving these issues.

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 replacement battery accepts and holds a full charge, resting at 13.06 volts after recharge. The previous battery passed a printed conductance and load test. During each failure, the entire camera system and the ParkSense park assist system drop out simultaneously and the odometer flashes. Stored codes include U0159-00 (lost communication with parking assist control module) and B2204-00 (ECU configuration mismatch). Separately, and even when the 12-volt system is healthy, the rear backup camera intermittently fails to activate at startup and sometimes only begins working after 5 to 10 minutes of driving. Safety concerns: 1. Rear visibility. The backup camera intermittently does not display an image when the vehicle is placed in reverse. 2. Loss of motive power. 3. Stranding

I received the following from the dealer when taking my car in for a suspension repair. Stellantis (Jeep) is trying to charge for software bug updates after warranty when the fixes were not available and also the without the fixes it could leave the car inoperable.
