2024 Jeep Grand Cherokee Fuel System Problems

The vehicle was in Hybrid mode. My wife was driving and had slowed to enter a roundabout to yield to another vehicle. When she accelerated and entered the roundabout, the vehicle stalled / shut itself off and flashed Service Hybrid System. She had to coast to a stop as it lost all propulsion. The vehicle started again after shutting it off and letting it go to sleep by opening the door. This same issue happened while slowing, then accelerating into a roundabout while I was driving a few weeks before in "Electric" mode. During this event, it stalled in the middle of the road and was blocking traffic. I had to shut the car off, open the door, wait, then restart it by going to "sport mode" to get the gas engine started.

Vehicle: 2024 Jeep Grand Cherokee 4xe Limited Issue Type: Fuel System / Fuel Gauge / EVAP / Hybrid Interaction Safety Concern: Incorrect fuel-level indication, fuel overflow, unreliable range estimation Description of the Problem: The vehicle’s fuel gauge and range indicator have become inaccurate and erratic. The gauge showed about 95 miles remaining, then dropped rapidly to a low-fuel warning. At the gas station, the pump shut off at approximately 8 gallons, even though the vehicle indicated low fuel. When I manually resumed fueling, gasoline immediately overflowed from the filler neck. There was no gasoline smell prior to this event. After driving away from the station, the remaining range increased, then decreased again, fluctuating by about ±10 miles. The fuel gauge and range readings continue to be inconsistent and unreliable. These symptoms began recently and are getting worse. The vehicle is currently being operated in Hybrid mode only due to an existing recall advising not to charge the battery. This issue creates a safety risk because: The fuel gauge may not reflect the true fuel level, Overflow during refueling poses a fire hazard, and EVAP or tank-pressurization malfunction may be occurring. Frequency: Problem has occurred on multiple consecutive refueling attempts. Safety Risk: Fuel overflow, inaccurate gauge, possible stalling or running out of fuel unexpectedly. Dealer: Issue reported; diagnosis pending. No modifications have been made to the vehicle.

My Jeep Cherokee 4xe is under an open safety recall for a high-voltage battery defect that can cause a fire while the vehicle is parked, charging, or driving. The manufacturer’s instructions require owners to NOT charge the battery and to NOT park the vehicle indoors or near structures. This makes the vehicle unsafe to store or operate. Stellantis has no remedy or repair timeline available. When I contacted Stellantis, they refused to escalate the case or provide assistance. The vehicle poses a serious fire hazard, and I am unable to use it for its intended purpose. I am requesting NHTSA review due to the severity of the safety risk and lack of remedy.

A current recall on vehicle reference to the propulsion and no remedy is available.

Fuel gauge does not display accurate fuel amount. Gauge is stuck in 3/4 full tank hereby misleading how much fuel is in vehicle. This is on a brand new delivered jeep. Risk of running out of fuel with no warning whatsoever.
