Ford Bronco Sport stalling problems

Filed Oct 26, 2026 · Fuel system, Transmission · OH

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.

On about 5 or 6 occasions over the course of one year, my brand new 2025 Ford Bronco Sport with the Big Bend trim with the VIN number in this report has completely lost engine power with severe engine hesitation with a highly rhythmic / even-patterned computer-controlled-like clicking and severe engine shaking (!!!) and a near stall while traveling from anywhere between 5 and 50 mph and the speed grinds down to a crawl, because it most often happens on an incline (maybe once on flat ground, and never downhill), and either way can be extremely dangerous! Fuel tank was full or half full on every occasion. Oil changed every 5k miles. Luckily at the higher speed, I was on a quiet hilly state highway road. I suspect it can happen at any speed though, which makes it even more dangerous! It is as if fuel stopped getting to the engine in these cases, or a computer failure in the fuel system, but I can be completely wrong about the cause. It is impossible to recreate on command obviously, being that it only happened 5 or 6 times over the course of one year, so neither myself or the dealer can recreate it on command. I complained about it to my local dealer that I bought it from, but they said they saw no codes stored, and of course couldn't recreate it. They suggested I got bad gas, but it has happened this many times. Impossible. It began happening at about 5k miles most noticeably. I currently have 12k or so on it. It's not like a throttle body or any injector or fuel system should be so dirty to cause this at the vehicle's age. No way. This is extremely dangerous. The dealer will not investigate further. Note: When this problem doesn't occur, then engine seems to run well, which leads me to think it is a fuel system / pre-engine problem, if I had to guess. I will include the first most noticeable date. I was driving much more in the first few months of the vehicle, but I let the car break in at speeds below 60 for the first 500 miles or so. I use 87 or higher octane.

My 2022 Ford Bronco Sport exhibits severe engine knocking and low fuel pressure, which are primary symptoms of open safety recalls 24S16 and 25S76. On 9/29/26, Seelye Ford of Kalamazoo charged me $220.21 out-of-pocket for a powertrain recall system software update. They are now refusing to inspect the physical fuel injectors or complete the safety recalls unless I pay out-of-pocket to replace an unrelated push-to-start button module, holding a federal safety recall hostage. The vehicle continues to malfunction identically after their software flash, making it a severe stalling and fire hazard. It is currently stranded on the dealer's lot.

After refueling car the car will not start after several attempts. Brought into ford dealership they said they cannot locate issue. They said have a small EVAP leak but would not repair unless a large leak and this would not cause an issue, but online this is exactly the cause of this problem. Additionally now 3rd battery to replace in only 5 years and they claim this is normal. In the past this car has spontaneously turned off while driving as well.

The vehicle's entire powertrain and transmission system failed completely. The vehicle will not turn on, will not start, and the electronic rotary gear shifter is physically locked out, refusing to shift into Park or Neutral. The transmission assembly component is currently available for physical inspection upon request. The sudden loss of powertrain and electrical control module communication caused an immediate loss of motive power, stalling the vehicle and leaving it completely stranded and un-drivable. The physical lockout of the shifter mechanism prevents rolling or shifting the asset safely, creating an immediate rollaway or crash hazard if stranded on an active roadway. The car was also jerking vilolently in the middle of an intersection almost causing an accident where we would’ve been rear ended. Yes. The failure was formally diagnosed and confirmed by an authorized dealership, Jim Taylor Ford in [XXX], under Repair Order (RO) #XXX. The component has been physically inspected and diagnosed by the certified technicians at Jim Taylor Ford dealership, who confirmed a total internal failure. They have ordered an entire replacement transmission assembly under Ford Part Number LX6Z-7000-F and Fluid XT-12-QULV. Symptoms and warning signs began showing around XXX, starting with minor shift jerking then eventually turning into violent jerking within a few days. The vehicle suffered from electrical system degradation and complete module power loss, which directly aligns with the known failure symptoms of Ford's active Powertrain Control Module (PCM) and battery safety recalls (such as Campaign 24S24). Ford Corporate was contacted but is refusing to cover this catastrophic mechanical destruction under the safety recall mandate due to the vehicle's mileage (118,365 miles), despite the physical damage being explicitly caused by the unaddressed manufacturer safety defect.

I've had a Blindspot warning light alert, told by dealership this is an electrical issue, after a web search, I see this is a common and known issue for Ford, yet no recall has been issued. I also have another know, common powertrain issue with my rear differential. The vehicle makes noise when turning, unstable when driving. The vehicle is less than 5yrs old and under 60k miles. Both issues are safety issues and could cause an electrical fires or vehicle stalling. I am scheduled for a 2nd inspection on 7/31 and hopefully repair.

This is a fourth occurrence related to the federal safety agency complaints 11749893, 11750183, and 11751201. The vehicle was previously diagnosed and repaired under warranty for the same 'Shift System Fault: Service Required' condition (transmission main control valve body replacement, RO #609213, completed July 21, 2026). Approximately 14 hours after pickup, on July 22, 2026, the identical fault recurred, the Check Engine light illuminated, and the vehicle died while driving. The vehicle was towed to Bowen Scarff Ford in Kent, WA and checked in the same day (RO #609522) for further diagnosis. This is now the second documented repair attempt for the same defect.

I was in another town and my car kept stalling. I was going across traffic and it stalled and almost caused an accident. When I was in a parking lot my car would not go in reverse. I had to be pushed out of the parking space. I have already went to the have this recall fixed once. I know the part is not available but I should not have to keep going every few months to keep getting this done on a vehicle that I am paying on. It is not reliable and I could have caused an accident.
