2022 Jeep Grand Cherokee

My 2022 Jeep Grand Cherokee 4xe has developed a recurring safety defect involving the front passenger seat lumbar-support system. Without any input from the passenger or driver, the pneumatic lumbar bladder will randomly begin inflating and continue until it reaches maximum inflation. When this occurs, the lumbar support protrudes significantly into the seatback and forces the passenger’s torso forward from the normal seated position. The passenger cannot reliably stop or reverse the inflation using the seat controls. This can interfere with proper seating posture and seat-belt positioning and creates a potential safety risk, particularly if the malfunction occurs while the vehicle is moving. There is no readily accessible owner method to manually vent or deflate the bladder when it becomes stuck. Correcting it directly would require disassembling the seat or accessing pneumatic components, potentially affecting warranty coverage. As a result, the passenger seat can become effectively unusable until the vehicle is serviced. The malfunction is unexpected, can distract the driver and passenger, and physically alters the occupant’s seating position without command. I believe this is more than a comfort issue and represents a potential safety defect in the powered/pneumatic seat system. I am requesting that NHTSA investigate whether similar unintended lumbar inflation failures are occurring in other 2022 Jeep Grand Cherokee and Grand Cherokee 4xe vehicles and whether manufacturer corrective action or a recall is warranted.

The Evaporator AC Core/Expansion valve was faulty, which is VERY common in these vehicles. The dealership fixed it (still has a noise so not 100% sure if it was fixed or if it's another faulty one). Leaking air conditioner refrigerant is hazardous to both human health and the environment. When these things leak it releases toxic chemicals into the air and atmosphere. The dealership confirmed the issue and fixed it which took 5 days to do and a TON of hours which cost me over $3000. I have complained to Jeep/Chrysler and they will do nothing. It should be a recall in these vehicles and the consumer should not have to pay for bad/faulty parts. My vehicle was inspected by two dealerships to get second opinions. I was told by the dealerships they are doing these repairs more than they would like to say. No warnings just a annoying sound when the AC was on and I would lose Freon constantly and my AC would go warm. I'm asking for something to be done. Thank you.

​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 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 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 just experienced a 2nd engine stall event. I was driving thru a neighborhood at 25 mph in 5th gear, lifted off the gas pedal as I approached a 90 degree uphill turn, and in the middle of the turn (approx 20 mph) the engine stalled and I lost all propulsion. I retired from Stellantis after 16 years working as a contract transmission calibrator, so I am very familiar with what happened. When I lifted off the gas pedal the engine attempted to enter decel fuel shut off (dfso). I was watching the real time gas mileage and right before the corner I saw the mpg approaching 99 mpg (a clear indication the engine is entering fuel shut off). A second later the real time mpg started decreasing (indicating it was attempted to exit dfso) when the stall occurred. This is a MAJOR SAFETY ISSUE in need of a recall.
