My 2015 Jeep Wrangler has experienced multiple incidents of sudden, unexpected engine shutdown while driving. Without warning, the engine completely loses power, causing the vehicle to lose propulsion and power steering assistance. The dashboard lights and radio remain operational during these incidents. I must turn the ignition off and restart the vehicle, after which the engine starts immediately and operates normally. The vehicle previously experienced similar problems involving additional electrical malfunctions. The fuel pump was subsequently replaced, and the camshafts and rocker arms have also been replaced. Despite these repairs, the engine has unexpectedly shut off approximately two or three additional times. These incidents occur intermittently and without warning, making them difficult to reproduce during dealership inspections. I am concerned that the vehicle could suddenly lose power in heavy traffic or at highway speeds (as it’s done previously even in the pouring rain), potentially resulting in a serious collision. The underlying cause remains undiagnosed and unresolved.

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.

Jeep purchased new on 28 January 2026. Fuel gauge only goes to 7/8 full after tank is full. Took it to dealer, they replaced gas tank, then 2 weeks later fuel pump twice, and fuel sensor unit. This solved the problem for 32 days now it’s doing the same thing. Took it back to dealership, they stated there was nothing they could do and engineering is aware and working on a fix. Called another Jeep service they said they weren’t aware of any updates or recalls.

On April 13, 2026, at approximately 67,312 miles, my vehicle experienced a fuel system failure when the main fuel supply line leading to the high-pressure fuel pump cracked and began actively leaking raw gasoline onto the top of the transmission in the engine compartment. There were no prior dashboard warning lights or error messages; the only symptom leading up to the failure was a extremely strong odor of raw gasoline coming from the engine bay area. I believed this fuel leak created an immediate, severe risk of an engine compartment fire. I immediately brought the vehicle to an authorized factory dealership, where certified technicians acting on behalf of the manufacturer inspected the system, confirmed the active leak emitting raw fuel odors, and successfully removed and replaced the failed supply line to resolve the issue. If needed, the vehicle is available for inspection upon request. Furthermore, my vehicle is factory-equipped with the 2.0L Turbo engine, meaning this failure is identical to the documented fire hazard covered under FCA Safety Recall Y10 (the federal safety agency Campaign 21V‑665). Even though my specific production sequence was not actively flagged under the manufacturer's recall lookup system, I believe the component failed in the exact same hazardous manner described in the official recall.

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.
