Ford Bronco Sport jerking 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.

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

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 am experiencing severe drivetrain binding and violent shuddering/chatter from the Rear Drive Unit (RDU) during low-speed turns in both directions. The vehicle hesitates and can stop violently on its own while turning. When the vehicle is parked and shut off, it also violently jerks backward, indicating the RDU is binding and storing mechanical tension. This is a significant safety hazard. The symptoms match the current Ford Technical Service Bulletin TSB 26-2328 (Chatter/Shudder During Low Speed Turning Events), which supersedes earlier bulletins including 26-2194 and 25-2351. I first reported the RDU issue along with a rear brake noise at the dealership and provided the relevant TSB numbers. The dealership stated the RDU was fine, performed only the brake TSB, and attributed the shudder to the brakes. After the vehicle was released, the RDU symptoms returned approximately 100 times worse within two days. On the return visit the dealership said they could not reproduce the concern and initially documented it as “just a noise.” I have repeatedly asked Ford (case management and Business Operations) whether the vehicle is considered safe to drive or sell in its current condition. I have not received a clear written answer. The original dealership has also refused to give a direct safety answer. I am requesting that this safety-related RDU condition be properly investigated and repaired.

The vehicle is only a 2022 and has a jerky acceleration during non-highway driving with RPMs fluctuating. The tire, cruise control and seatbelt indicator lights are illuminated with no resolvable issue (the dealer clears them out and they come back). There’s an audible muffler rattle that has been present for a long time that the dealer says is normal. When I fuel up the engine audible bogs down. On a recent road trip to New York the vehicle vapor locked at a gas station and had to be jumped. The vehicle has been nothing but recalls and issues

THIS PROBLEM CAUSES MY VEHICLE TO SPUTTER AND JERK WHEN TRAVELING. I brought it to the dealership and they said to bring it back when the recall was submitted. This is ridiculous. So many recalls on this vehicle

I have 130,000 miles on my 2021 Ford Bronco sport. With no warning I'm unable to put vehicle in gear. I attempt to put the car into drive, then reverse and it will not go. The gear gets stuck in park, but unable to park, The car instructs me to intiated emergency park with many warning lights appearing. when driving it jerks , make grinding noises, and I even lost momentum. Ford said the help line states they have attempted to fix the codes and replace the parts on the inside of the transmission and no luck. Ford recommends a new transmission. I believe the 2021 Bronco sport have a faulty transmission and replacing with another will result with the same issue due to the transmission being a close system it isn't preventable. Many other owners have experienced this very same safety issue and Ford should address ot and be responsible.

2023 Bronco Sport had its serpentine belt replaced in February of 2026 because it was loose causing my engine to overheat. I had to have it towed because I was sitting on the side of the road. Then in April of 2026 the Bronco started making horrible loud clanging sounds and jerking when it was put in gear. Towed again to the shop. Now I am told this 3 year old car needs a new transmission. Doing research i have found that several Bronco owners have the same problem. Why does Ford not have a recall for this!! My mechanic was looking for a rebuilt one and can't find one because the demand for them is higher than what the supply is. This should tell you something!!

On December 13, 2025, we drove to Flagstaff, Arizona from Tucson, Arizona, where we live. As we came into town, the Bronco began to lurch and seemed to have difficulty shifting. I managed to make it to the Babbitt Ford service center’s parking lot, where it seized and died altogether. It stayed at Babbitt Ford where they worked on it until February 3, 2026. They replaced the transmission at great expense. On Feburary 3, we drove it home to Tucson. The next day, February 4, it died in the road twice, once in a major intersection. The first time it eventually resarted. The second time it died completely and required a special tow truck because we couldn't even get it into neutral to roll. It was towed to Holmes Tuttle Ford where they kept it for a week but were able to eventually restart it. They had it for 5 days, ran a diagnostic and reset the system. They drove it for over 80 miles and couldn’t recreate the problem. Then on February 25, I drove to Phoenix. While in Phoenix, it again inextricably had trouble shifting, died and wouldn’t start. I then had it towed to Camelback Ford. On March 6, Camelback Ford called and said they ran numerous tests and still can’t pinpoint the problem and the vehicle still won’t start or shift into neutral.
