POWER TRAIN, VEHICLE SPEED CONTROL, ELECTRICAL SYSTEM
My car would not move or go into gear. I was told it was my transmission but the diagnostic said it’s my powertrain control module. The mechanic finally admitted he broke my transmission. My Bronco is still sitting at the service department of the dealership. I have not had my vehicle since June 6, 2025. All I get is still ordering parts! I need a vehicle this is my only source of transportation and now I’m borrowing daily from family members. I don’t understand why they didn’t look into the powertrain from the beginning.

So the window switches are cutting my fingers. Whatever was used to coat the switches peels like sturdy tin foil and has sliced my fingers multiple times as well as my passengers. I had to peel that coating off the switches so no one keeps getting injured in my vehicle. I just bought this car used in April and it cut me the first time I got in it I wasn't thinking of anything until it kept cutting me and other people.

I have 66,310 miles on my 2021 Ford Bronco Sport and recently found out that it needs a new transmission. Their quote for the transmission was $13,000… yes you read that right $13,000!!!! More importantly is the fact that the transmission crapped out at 66,310 miles… The dealership (Stamford Ford) told me there was NOTHING they could do as the warranty expired at 60K miles. After some research online it turns out that FORD BRONCO IS PLAGUED WITH TRANSMISSION ISSUES AND THEY REFUSE TO RECALL THEM. There are literally thousands of complaints from people with the same issue

ENGINE, ELECTRICAL SYSTEM, POWER TRAIN
Since I have bought this used vehicle in September 2024, it has been shutting off completely with having to restart the engine. There was a recall for the battery in January 2025 that was finally approved to be replaced maybe in May or so. Battery was replaced but it keeps shutting off. I just took it in July 7 for the fuel pump to be replaced as they said that was the final cause. I drove it home the same day when it was finished and it has been shutting off still. It has shut off while I have been at the light, in reverse and as well as putting my vehicle into reverse by itself which could cause an accident. This situation has since be unresolved. I have taken it to the ford dealership with them many times with them saying there is nothing wrong with it.

POWER TRAIN
I have a 2021 Bronco sport Big Bend with only 27,000 miles on it. it I started to notice a binding sensation and accompanying noise from the rear of the vehicle when making sharp low speed turns. I took it to the dealership and they thought it was a brake problem but nothing was found from this inspection and the noise persisted. Then I took it in and had the rear differential inspected and found that the axle retaining clip is broken or has fallen off and the axle is pounding on the retaining pin. The Tech told me that this is a very common problem with Bronco sport Big Bends and requires replacement of the entire differential and the axel shaft, this is a four thousand dollar repair on a lightly used vehicle with low miles. The dealer says there is a national back order on these parts as this is such a common problem with this model.

ELECTRICAL SYSTEM, ENGINE, POWER TRAIN
Vehicle: 2021 Ford Bronco VIN: [XXX] Mileage: Approximately 88,000 miles Complaint: I am reporting major safety and drivability concerns with my 2021 Ford Bronco, which is currently undrivable and in the shop at Ron DuPrat Ford in Dixon, California. Despite experiencing issues nearly identical to those covered under existing recalls, my vehicle’s VIN is not currently included. While driving on the freeway, the vehicle suddenly malfunctioned. Without warning, it dropped into first gear at high speed, causing a rapid and unexpected deceleration. This could have easily resulted in a serious accident or even death — not only for my family but for others on the road. This is a major safety issue. After pulling off the road, the vehicle would no longer go into reverse and became completely undrivable. I also received multiple dashboard alerts, including: “An electrical fault has occurred with the transmission fluid pressure sensor circuit and its associated wiring.” “Powertrain Malfunction / Reduced Power” “A Powertrain or All Wheel Drive (AWD)/Four Wheel Drive (4WD) fault has been detected.” This is our main family vehicle, used daily for commuting and travel. I am still making payments on it, and the fact that it has become unsafe and unusable at this mileage is unacceptable. If this vehicle was not built for long-term use or daily driving, that should be clearly stated not discovered through dangerous failures like this. I no longer feel safe transporting my children in this car. I strongly urge the NHTSA to investigate whether the current recall coverage should be expanded to include additional VINs like mine. This appears to be a serious safety defect that poses a risk to drivers and passengers and requires immediate attention.

STEERING, POWER TRAIN
Vehicle chutters especially turn low speed turns and after stopping and making turn. You can feel vibration in the steering wheel and can be jerky turning. I have read of multiple other reports of this happening to vehicles and there is a TSB (24-2185)out for the repair. Ford knows about it and should be liable for the fix.

Parked my car, came back to it and it would not engage in gear. Put it in reverse and it will not go. Put it on forward and it would go. After a little bit it would not engage even if I put the car in reverse or forward. Car did not give any indication of transmission issues at all. No weird sounds or rough gear. Flushed transmission fluid (black color) and got original ford trans fluid in it. It engages but it is rough and not driveable. Car did not give any indication of transmission problems at all before the issue. Transmission is bad.

ELECTRICAL SYSTEM
I am reporting a serious safety issue with my 2021 Ford Bronco Sport. The vehicle developed an internal AC leak due to a clogged AC drain. This leak caused water accumulation inside the cabin, leading to extensive electrical system failure, including loss of power steering, multiple warning lights, and a dead battery. The vehicle is no longer drivable. Upon researching online, I found that numerous other owners of 2021 Bronco Sports have reported the same clogged AC drain issue resulting in internal leaks and electronic malfunctions. This appears to be a systemic design flaw and should be investigated for safety recall consideration. I am submitting this complaint for documentation and to request that NHTSA review the frequency and severity of this failure, especially given the risk of electrical failure while driving. Component/System Failure: The air conditioning (AC) system drain became clogged, causing water to leak inside the vehicle cabin. This leak led to corrosion, mold/mildew buildup, and multiple electrical system failures, including loss of power steering, a dead battery, and numerous dashboard warning lights. The AC system and the resulting damage are available for inspection upon request. Safety Risk: The electrical failures caused by the leak created a serious safety hazard. Loss of power steering and critical electrical systems while driving could cause loss of vehicle control, increasing the risk of an accident. Additionally, mold growth inside the cabin poses health risks to occupants. Problem Confirmation: The issue has been confirmed by an independent service center that diagnosed the clogged AC drain as the root cause. Other 2021 Ford Bronco Sport owners have reported identical problems, indicating a widespread defect. Inspection by Others: The vehicle has been inspected by independent mechanics and the dealer service department. Ford corporate has been notified but has not acknowledged this as a recall or defect.

ELECTRICAL SYSTEM
I experienced a full loss of battery power with my 2021 Ford Bronco Sport, which I later learned is related to an open recall (Ford Recall #25S02– related to 12V battery defect). Prior to receiving the recall notice, I paid out of pocket to replace the battery after the vehicle failed to start. I brought the issue to my local Ford dealer. At this point, they removed the battery I had just purchased and installed another without fully explaining the claim process or giving me written confirmation that the claim was filed. I escalated the issue to Ford Corporate, and was told the dealership service manager has approval authority. However, I remain without confirmation of reimbursement and the process has been vague and uncooperative. I also had to track down the battery purchased and installed by Roadside Assistance myself. The recall letter clearly states that customers may be eligible for reimbursement for prior battery replacement due to this defect. This entire experience raises concerns about how seriously Ford and its dealers are handling safety recalls and reimbursement obligations.
