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.
