2021 Ford Bronco Sport fuel system problems

Filed Nov 4, 2026 · Engine, Fuel system · AZ

I am filing a safety complaint regarding my 2021 Ford Bronco Sport 1.5L and Ford Motor Company's handling of recall-related repairs. Beginning October 22, 2025, I repeatedly attempted to have the applicable recall work completed through two authorized Ford dealerships. The programs involved include: • Recall 24S24 – the federal safety agency 24V267000 • Customer Satisfaction Program 22N18 – the federal safety agency ID 10233848 Despite multiple dealership visits and Multi-Point Inspections, the work was not completed until November 4, 2026. During this period, my vehicle experienced significant loss of engine power, particularly when traveling uphill and at higher elevations. Powertrain warnings also appeared, creating potentially dangerous driving conditions, especially on highways where maintaining speed is critical. The vehicle is now experiencing a failing turbocharger and other major mechanical problems. My concern is that these issues were overlooked or not properly investigated during previous dealership inspections. Had the necessary work and inspections been performed in a timely manner, these problems may have been identified before my 60,000-mile factory warranty expired. I am now facing substantial repair expenses as a result. I contacted Ford Motor Company's corporate Customer Relations department but was told they could not help. My complaint is not simply about warranty coverage or repair costs. I am concerned about the safety implications of the vehicle's loss of power, the delayed recall work, and whether the recall remedies adequately address the underlying problems. I respectfully request that the federal safety agency review the recall history, investigate the reported loss of power and engine failures, and determine whether additional safety action or investigation is warranted.

The contact owns a 2021 Ford Bronco Sport equipped with an 8F35 automatic transmission. While driving between 25 and 45 MPH under normal acceleration, the vehicle experienced repeated violent hesitation, jerking, and lunging 4 to 5 times in rapid succession, accompanied by rapid RPM fluctuations between 2,000 and 3,000 RPM. The condition mimics an engine misfire or momentary stall and loss of motive power during acceleration, creating an immediate safety hazard and risk of rear-end collision in active traffic. The vehicle was taken to an authorized Ford dealership (Cronin Ford North) on September 30, 2026. The dealership verified and duplicated the complaint on a road test, monitored PIDs, and officially confirmed that the torque converter clutch (TCC) was slipping. Despite confirming mechanical slip, the dealership stated in writing that there were "no relevant articles," overlooking the published Ford Special Service Message SSM 54797 for 8F35 torque converter shudder below 60 MPH. The dealership recommended replacing the torque converter and main control valve body for over $5,200. When the owner declined due to cost, the vehicle was released back into service without answering the owner's written safety inquiry regarding whether the vehicle was safe to operate with verified drivetrain slippage. Additionally, the vehicle has an open safety recall (25S76) for which Ford corporate confirmed no remedy or parts are currently available. The vehicle has not stalled completely, but the severe hesitation and surging persist under normal acceleration. The manufacturer has not provided a resolution.

The vehicle was taken to an independent mechanic, where it was determined that fuel was not reaching the engine. The dealer was contacted and informed the contact that there was no open recall on the VIN. The vehicle was no longer driven due to the safety issue. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair.

I have had issues dating back to when I first got the car with rough idling and it turning off while idling. Most recently about 2 weeks ago experienced inability to turn the car on after fueling with gas. Rough idling and turning off while idling were also associated with gas filling. I took this car to Ford dealership multiple times. Check engine light came on associated with EVAP leak code. Ford dealership unable to diagnosis. I took to an independent mechanic who diagnosed in 10 minutes it is an EVAP purge valve malfunction and that likely this had been defective for some time. I reported this to ford and they refuse to compensate for this. I have seen multiple reports online of same issue with other ford bronco sport dealers. This failure seems abnormally premature and defective design. Concerning it results in loss of power of the vehicle as well.

My vehicle is subject to open the federal safety agency recall 25S76 regarding a fuel injector that may crack and cause fuel to accumulate on top of the engine near hot surfaces, creating a fire risk. This recall was identified months ago, but Ford has stated parts are not currently available and no repair date has been given. I have not received any further communication or updated timeline since the recall was issued. In the meantime, my vehicle has also been experiencing intermittent jerking during acceleration between approximately 40-50 mph, which I am concerned may be an early symptom of the injector issue described in this recall. I am continuing to drive the vehicle because no remedy is currently available, but I am concerned about the extended delay in providing parts for a safety recall involving a known fire risk. I am requesting that the federal safety agency review the length of this delay and Ford's plan for remedying affected vehicles

On 9/15/26, while actively driving with my child, the monitor screen suddenly turned black and an error message of "Vehicle Network Communication Error", a few seconds later my dashboard turned black, no display messages, speed limit, or manual gauges were working and that too went blank; blinkers did not work when trying to use them. Luckily I was a short distance from where I was traveling to and when we arrived I turned off my car to see if i restart it, it would reset my car. It did not work. My car did not turn on, did not crank- the light on my start button just flashed rapidly. It was not until after my husband later arrived he disconnected the negative battery terminal and let it stay disconnected for 20-30 minutes and it then restarted. Case #CXH-09342591-W5K1G2 was filed with Ford Customer Relations, but they said further information regarding the case would likely not be provided to me as an update.

My 2021 Ford Bronco Sport is subject to Ford Safety Recall 25S76 / the federal safety agency Recall 25V467 concerning cracked fuel injectors that may leak fuel and create an under-hood fire risk. This recall was issued in July 2025. Approximately 14 months later, Ford still has not made the final repair available for my vehicle. I had Ford’s interim PCM software update performed by an authorized Ford dealer on December 12, 2025. My repair order specifically identifies the work as “Campaign number: 25S76 POWERTRAIN CONTROL MODULE PCM SOFTWARE UPDATE.” The replacement parts necessary for the final remedy have never been installed on my vehicle. Ford has repeatedly moved the anticipated availability date for the final remedy. I was previously told September 2026. On September 4, 2026, after spending approximately an hour on the telephone with Ford, I was told it could now be October. I am also concerned about the information Ford is providing to owners through its own app. Despite the fact that the final recall remedy has not been performed on my vehicle, the Ford app currently displays a green checkmark and states “0 active recalls.” There is also no unresolved recall shown in my alert history. This creates the impression that my vehicle has no outstanding safety recall even though Ford confirmed to me that the permanent remedy has not been completed and the required replacement parts are still unavailable. I am concerned both about the approximately 14-month delay in providing a final remedy for a defect involving potential fuel leakage and fire, and about Ford’s consumer-facing system representing that there are zero active recalls after completion of only the interim software update. I am requesting that the federal safety agency review Ford’s continuing delay in providing the final remedy for Recall 25V467/25S76 and the manner in which Ford is communicating the recall status to owners who have completed the interim software update but have not received the final remedy.
