We have been experiencing an intermittent gas leak for two years. We have taken it to AutoNation Jeep several times for this issue but they haven’t been able to reproduce the problem. We have provided video evidence and opened a case with Jeep, Case XXX, but nothing has happened for two months now. We have a lifetime warranty on the Jeep and have asked that they replace all possible parts. Jeep approved this but the dealership refuses to do the work. We are left with an unsafe vehicle that leaks gas. If you go through this video frame by frame you will see the gas on the undercarriage. I did not trace it to the source, but you can clearly see the gasoline traveling and then dripping onto the ground. I had driven the car maybe 50 ft up my driveway when I smelled the gasoline and got out to film. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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.

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.

Every time the vehicle is filled with fuel it overfills and a large amount of fuel spills in the vehicle and ground. This is a safety concern which can lead to a fire unexpectedly. Upon inspection the fuel tank control valve has been found to be inoperative and can cause a fuel leak during a vehicle rollover event, debris in the fuel tank, and/or the ability to overfill the fuel tank during refueling. A fuel leak during a vehicle rollover event, in the presence of an ignition source, could cause a fire without warning and lead to death. The vehicle is not shown to have an outstanding recall though this year and model does have a recall for a limited number of the production.
