“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 – NHTSA 24V267000 • Customer Satisfaction Program 22N18 – NHTSA 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…”

“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…”
