I own a 2021 Jeep Wrangler Rubicon 392 with the 6.4L engine (VIN: [XXX] ). The vehicle has a dangerous condition where the engine stalls unexpectedly when the fuel level is approximately 1/4 tank or lower and the vehicle is traveling downhill. When the vehicle is positioned on a decline or downhill slope, the engine suddenly shuts off without warning. This appears to be fuel starvation on decline when the fuel level is below approximately 1/4 tank, resulting in engine stall and loss of power steering and braking assist after stall. This has occurred multiple times and creates a significant risk of crash due to the sudden loss of engine power and reduced steering and braking assistance while the vehicle is in motion. The issue is particularly concerning when descending hills or driving on angled terrain. The vehicle was taken to an authorized dealership (Carvana Jeep San Diego) where technicians determined the likely cause is a defective fuel pump module associated with the Wrangler Rubicon 392 6.4L fuel pump module. However, the dealership informed me the replacement fuel pump module is currently on national backorder from the manufacturer (Stellantis/Jeep). They stated there is no confirmed availability date and that many vehicles may be waiting for the same component. My vehicle has been awaiting repair for approximately four months due to the unavailable fuel pump module. Because the vehicle can stall unexpectedly while traveling downhill, this defect presents an ongoing safety hazard and potential risk of crash. This complaint is being submitted so the issue can be evaluated as a potential safety defect involving fuel delivery failure, fuel pump module malfunction, and engine stall under low fuel conditions in the Jeep Wrangler Rubicon 392.
