The contact owns a 2021 Jeep Wrangler. The contact stated that while driving 40 MPH, the vehicle lost motive power. The contact was able to turn onto a side street and pull over to the side of the road. The vehicle was towed to a dealer, where it was diagnosed and determined that there was a catastrophic failure of the fuel pump resulting in the fuel lines being contaminated with metal shavings. The contact stated that a fuel injector cleaning service was completed approximately one week prior to the failure. The dealer informed the contact that the entire fuel system needed to be replaced, and the engine needed to be flushed. The contact was provided an estimate for the repairs. The vehicle was in the process of being repaired. The failure mileage was approximately 67,000.

Follow-up to complaint 11749455, same vehicle (2021 Jeep Wrangler EcoDiesel, approx. 98,300 miles). Following recall 01A (high-pressure fuel pump replacement), a diesel fuel leak was discovered at a fuel supply component by the servicing dealership. That fuel injector supply line was replaced on 07/23/2026, which I paid for under protest. Within approximately one mile of leaving the dealership, the vehicle began leaking diesel fuel heavily and was returned the same day. The dealership then identified injector O-rings as the source and replaced them; after that repair, fuel injector #1 is now leaking. This is the third distinct fuel-system leak repair on this vehicle following recall-related service, and none has resolved the condition. The vehicle was released to me in a leaking, unsafe condition after a paid repair that did not fix the leak. The failed components have been confirmed and worked on by the dealership and are available for inspection. Concern: repeated diesel fuel leaks in the engine compartment present a fire and roadway hazard, and recall-related fuel system repairs have not reliably resolved the problem.

Subject: Safety Complaint – 2021 Jeep Wrangler 2.0L Fuel Pump Failure (Loss of power while driving.) I am filing this complaint regarding a 2021 Jeep Wrangler equipped with the 2.0L engine due to what I believe is a significant safety issue involving the fuel pump. The fuel pump has failed, making the vehicle unsafe and/or inoperable. A sudden fuel pump failure can cause the engine to lose power or stall without warning, creating a serious safety hazard, especially when driving at highway speeds, in heavy traffic, or while crossing intersections. A loss of engine power in these situations places both the driver and surrounding motorists at risk of a crash. What is equally concerning is that the replacement fuel pump is currently on a national backorder, with my dealership estimating approximately 45 days or longer before the part will be available. This suggests that many owners may be experiencing the same problem and that replacement parts cannot keep up with demand. As a result, my vehicle is unusable while I wait for a critical safety-related component. This creates a significant financial and personal hardship, including transportation difficulties, missed work, and additional expenses. A safety-related component should not be unavailable for such an extended period if this issue is affecting numerous vehicles. I respectfully request that the federal safety agency investigate whether fuel pump failures in the 2021 Jeep Wrangler 2.0L represent a widespread safety defect. If a pattern is identified, I urge the federal safety agency to require Stellantis to issue a recall or other appropriate corrective action to protect vehicle owners and the public. Thank you for your consideration of this complaint.

Vehicle received federal recall 01A service (high pressure fuel pump replacement) at an authorized Chrysler/Jeep dealership on 05/14/2026 at 97,055 miles. I drove the vehicle normally for approximately two weeks (roughly 950 miles), then parked it in my garage awaiting a separate warranty part for the intake manifold. On 07/03/2026, during that warranty repair at the same dealership at approximately 98,000 miles, the dealership’s own technician discovered a diesel fuel leak at the fuel injector supply tube. This line must be disturbed to access and replace the high pressure fuel pump during the recall procedure and is a single-use component. No fuel leak or fuel system issue existed or was documented before the recall service; the vehicle was scanned at the same dealership at intake and the only issue found was an intake manifold valve actuation code unrelated to the fuel system. The leak was confirmed by the dealership and the component is available for inspection; I have requested the removed part be returned to me. Safety risk: the vehicle was driven on public roads for roughly 950 miles while, unknown to me, a fuel line disturbed during recall service was developing a leak. Pressurized diesel leaking in the engine compartment is a fire and roadway hazard. The dealership is charging me for the part and labor rather than covering it under the recall remedy, which provides for replacement of additional fuel system components as necessary free of charge. My concern is an improperly performed or incomplete recall remedy resulting in a fuel leak.

The high-pressure fuel pump (HPFP) failed internally while I was driving at night, causing the vehicle to suddenly stall and shut off completely while my children were in the vehicle. This resulted in an immediate loss of power and created a dangerous situation in traffic. The failure caused metal debris to spread throughout the entire fuel system, and the dealership confirmed that the system requires full replacement. I was quoted approximately $15,000 for repairs. This vehicle previously had a manufacturer recall related to the fuel pump that was completed in 2022 and is now listed as closed. Despite the recall repair, the same failure occurred again. This demonstrates that the recall remedy did not correct the defect. The sudden engine shutdown without warning presents a serious safety hazard, especially at night and with passengers in the vehicle. Its been at the dealer ship for a month.

Vehicle stalled out. Then would not start. Daughter was stuck for 30 minutes until it finally turned over took it into dealership. Was told it’s the fuel pump. My issue is that now. These fuel pumps are back ordered indefinitely found out because all of the fuel pumps are going bad on the jeeps. Now we have a faulty part that the dealership is aware of that you cannot get replaced due to so many of them needing to be replaced, which tells me they know this part is faulty was told they’re not even sure if or when they would be able to get the part now you have all these people driving jeeps that can stall out on the road and get into a terrible accident. My daughter is [XXX] and this is not acceptable. She has a faulty car part and Jeep has no parts to replace this faulty part.

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.

Vehicle started and put in reverse. after backing up approximately 15 ft, vehicle put into driver and once accelerator was pressed, vehicle stalled. Tried to restart, engines turned over but stalled again after 1 second. Waited 10 seconds and tried to restart again, stalled again 1 second after turnover. Turned vehicle completely off, opened door, waited 30 seconds, tried starting again and system attempted to stat for 5-10 seconds (push to start ignition so I had no control over how long it tried this), but engine would not turn over. Vehicle also could not be shifted out of park (turned vehicle off and tried to put in “On” position without ever depressing the brake). Vehicle now stuck in driveway and unable to be moved. Acting like an issue with the fuel pump, which is a recall that was announced for some vehicles of this make and model, but the federal safety agency check shows no open recalls on vehicle. No warning lights or check engine lights came on.

Since we have had the high pressure fuel pump recall completed/replaced, there have been ongoing problems with the cooling system that cause overheating multiple times, on the same grade of road, during subsequent trips. The vehicle alerts and says it has overheated, and is stopped and allowed to cool off. Coolant is indeed low, but there are not any visible leaks and there is no puddling or areas where it appears to be leaking. We have had this issued looked at twice, several repairs completed, hoses replaced, reservoir replaced, and we are still having this issue. This appears to be something exclusive to the diesel motor, as we have friends with the same vehicle with gasoline engine that are not having this concern.

Part z96 high pressure fuel pump was recalled over a year ago with no parts or fix. I had been calling every 2-3 months to check and was informed the fix was not available. Over a month ago, the fuel pump failed and the car shut off while I was driving. Metal was sent through the entire fuel system. The whole fuel system needs replaced and the Jeep sits at the dealer with no parts available.

My diesel Jeep Wrangler has had an open safety recall for 12 months (Z96/the federal safety agency 22V‑767), related to the high pressure fuel pump. Jeep/Stellantis continually fails to address this issue and pushes the estimated timeline for repairs months down the road. Every time I call or bring my vehicle in for service, I am alerted to this open safety recall, then told there is no fix available. I have tried to trade my Jeep in several times over the last 9 months, but dealers have been unwilling to take a vehicle on trade with an open safety recall and no fix available.
