We experienced premature failure of the rear differential, which was told to us to be a "know defect" by our dealership service department. Ford has been made readily aware of this failure point and potential safety concern-- it is well-documented on the internet, including this NHTSA website, yet fails to issue the proper and appropriate recalls. Consumers are expected to foot the bill for this known manufacturing failure point, which is not only inappropriate, but also extremely dangerous. Failure of the rear differential carries a known potential risk of catastrophic failure-- an immediate recall should be issued for any models affected.

ENGINE
We purchased this vehicle 02/2025. The salesman stated there was a 5 point inspection and the car was good on fluids oil and brakes. We questioned the rough idle and odd sound the car made and we were told that it was normal. 07/2025 a mobile mechanic came out and repaired a recall. He stated in his notes that the car had an oil leak but he could not determine where. Fast forward to now, my car has been needing oil more than usual since we have got the car. There is a leak but it does not leak on the ground. 11/11/2025, I contacted Big Valley Ford in Stockton CA with concerns about the oil depleting rapidly and how my check engine light comes on which tells me my car has absolutely no oil. I mentioned a recall I saw online 22S21 and Greg (the man I spoke with) stated that was never a recall for my car. He saw the oil separator was replaced in 2022 but it was not for a recall. Greg then told me to make an appointment to bring the car in for a diagnostic and then an oil change. They would then mark my car where the oil is and have me come back in a few days to see how far the oil went down. I asked how much and he said 225 for the diagnostic and 135 for the oil change. Convinced he was lying to me, I called Ford in Tracy, CA and they confirmed there was a recall 22S21 for the oil separator. This car has given me so many problems and this issue clearly was never fixed and they sold me the car this way.

SERVICE BRAKES
On November 11, 2025, my 2021 Ford Bronco Sport experienced a complete brake system failure while driving. The brake pedal suddenly became extremely hard, and there was no braking power at all. The vehicle had to be stopped using the parking brake. This same issue occurred previously in July 2025, when the brake vacuum booster failed and was replaced at the Ford dealership. The problem has now recurred less than six months later. The vehicle is not safe to drive and is available for inspection upon request. My safety and the safety of others were put at risk because the brakes failed completely without warning while the vehicle was in motion. If traffic conditions had been heavier, a collision could have occurred. The issue has not yet been confirmed by the dealership for this most recent occurrence, but the same Ford dealer that repaired it in July handled the prior failure. The vehicle will be towed there again for inspection. No warning lamps or dashboard messages appeared before or during either failure. The only symptom was a sudden loss of brake assist and a hard, unresponsive brake pedal. This appears to be a repeated failure of the brake vacuum or brake assist system, which I understand has been part of a previous Ford recall (21C31) affecting 2021 Bronco Sport models. But my VIN number was not included in the Recall. This is my second reporting and needs to be recalled.

FUEL/PROPULSION SYSTEM
When I try to pump gas, I often will start the gas pump and then it will stop after only filling up about a third of a gallon. It doesn’t happen with every gas pump, but it happens frequently enough that it has become very frustrating. I end up not being able to put gas in my car at times and I have to drive to another gas station. I thought there had been a recall on this issue before and it had been resolved, but I have still been experiencing issues.

In 2024, we had our battery replaced in our 2021 Bronco Sport by the Ford certified dealer in response to Recall Number 24S24. We did not have any issues with the previous battery. They replaced the original battery with the AGM battery, which they represented would prevent the issues that necessitated the recall - catastrophic degradation of the battery and complete loss of drive power. In mid-October 2025, my wife experienced unexpected and complete loss of drive power when exiting the interstate in the car, and was stuck in the freeway exit lane as oncoming traffic was exiting at high speeds with minimal time to avoid the stalled car. It was a dangerous situation and the car was almost struck numerous times. No warnings or messages appeared - even the hazards did not work. After about 20 minutes, we were finally able to obtain assistance from a police officer and had the car towed to a Firestone a few blocks away. Firestone confirmed that the AGM battery had failed which caused the complete loss of drive power. They replaced the battery and reprogrammed the car as best they could, but the failure of the battery also destroyed a few computer chips that needed to be replaced by Ford in order to fully reprogram it. We took it to the Ford dealership that initially replaced the battery (10 miles away) the next day, and Ford refused to refund us the costs for towing the car and replacing the battery at the Firestone, claiming our situation did not constitute an "emergency" since we could have had it towed 10 miles to the Ford dealer rather than a few blocks to the Firestone. As we did not know what was wrong with the car, we reasonably chose the Firestone as the best option, since it was only a few blocks away. Ford replaced the computer chips under the recall, but we have still paid over $600 out of pocket due to this incident that Ford refuses to pay us. The Ford dealership also took the battery when we requested the refund, and has not returned to us the battery.

I am submitting this letter to report a potentially widespread safety defect in the 2021 Ford Bronco related to the rear differential assembly. Many owners, including myself, have experienced or are concerned about premature failure of the rear differential under normal driving conditions. This issue can lead to loss of vehicle control and represents a significant safety risk on public roads. Ford Motor Company appears aware of the recurring nature of this defect but has not, to date, issued a recall or extended coverage for affected vehicles. I am requesting that NHTSA investigate this issue as a possible design or manufacturing defect that warrants a formal recall or technical action from Ford. Description of Issue: Premature rear differential failure / widespread owner reports Problem has been reported to Ford Motor Company as well as Sutton Ford Dealership. They did the inspection and diagnosed it. I took my vehicle to that dealership numerous times and told them about the noise I was experiencing and it came back no problems found. This truck has had several recalls and problems since it rolled off the assembly line.

On 7/22/2025 Luther Ford, When asked to drive the vehicle into the service area, the car would not go in to drive. It would not move at all. The service advisor stated we need to have the transmission taken out and taken apart to see what the issue is. He said that the transmission was needing to be replaced, and with the transmission, it is mostly because of an issue with the motor as well, but this cannot be diagnosed until the transmission issue is corrected. The vehicle is still at Luther Ford in Fargo waiting on repair. Ford offered limited financial assistance for this. With myself still owing $5758.38. There have been multiple times that I have requested the dealership drive the vehicle because of the vehicle shifting hard or cutting out when stepping on the gas. On 3/3/2023 20,991 miles I had taken the vehicle in to RM Stoudt in Jamestown, ND because the car was shifting hard, and was cutting out while in low gear/speeds. I do have documentation of this. Nothing was done at this time by the dealership. 10/3/2024 46,277 miles I had the bronco into Devils Lake Cars for an issue with the CV Shaft and warranty work. I also asked them to drive the vehicle because it is STILL not driving correctly and is not shifting correctly and wanted it to be corrected before warranty was up. Nothing was done at the dealership. Before 60,000 I called Devils Lake Cars. I stated that the vehicle is still having issues. I was not going to be able to get to the dealership as I live in a remote area, until after it goes over the 5/27/25 62,354 miles I finally got an appointment and the vehicle in at Devils Lake Cars, they documented thatthey drove the vehicle and there were NO issues. I requested the next time that we are in, that we ride with the service agent so we can prove the issues we are constantly having. 7/22/25 2500 miles later, the car is no longer able to even be put into drive and this brings us to the current situation and the transmission is needing to be replaced

I took my vehicle into my local ford dealership to get three active recalls remedied. Within 24 hours, my check engine light reappeared as well as "service engine soon" on my way into work. Upon leaving work, the dash lights were gone. They would come and go periodically. After about a week, it would pop up "service engine soon" and within ten minutes, regardless of speed, the RPMs would fly all the way up and the vehicle would act as if I took my foot off of the gas, almost immediately stopping on the highway. I would have to almost immediately pull off of the road and my vehicle would stall, flashing "shift system failure" as well as failing to let me put the vehicle into park or any other gear. Taking it into the shop, they told me that was due to a software bug WHICH THEY JUST "FIXED" with a recall update. They also proceeded to tell me there is metal debris in my oil and I need my transmission rebuilt, quoting me $13,000.

After Ford completed Recall 25S76 on my 2021 Ford Bronco Sport (VIN [XXX] ), which involves replacing high-pressure fuel injectors due to the risk of cracking and fuel leaks, the check engine light returned immediately after the road test. The Ford dealer’s diagnostic confirmed: “After installing high-pressure fuel injectors, cleared codes, road tested and check engine light came back on, performed further P/P test, found high-pressure fuel pump with internal fault which caused a back-pressure concern and took out low-side fuel pump.” The high-pressure fuel pump and low-side fuel pump both failed immediately following the recall injector replacement, which appears to indicate a related fuel-system failure. Ford has stated these are not related issues and has only offered partial goodwill assistance, leaving a significant cost for the customer. Component/system that failed: Fuel system – high-pressure fuel pump and low-side fuel pump (available for inspection). Safety risk: A fuel-system failure can cause stalling or loss of power while driving, increasing the risk of an accident. Confirmed by dealer: Yes – documented in the Ford dealer’s diagnostic notes. Inspected by manufacturer: Yes – Ford dealer completed the diagnostic under Ford’s guidance. Warning lamps or symptoms: Check engine light returned immediately after recall work. No prior symptoms before recall repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The car would "skip" while driving. If paused at a light/stop sign, I would hit the gas and the RPMs would increase, but the car would not drive, then it would jerk and go. When driving, my foot would be at a consistent pressure on the gas, but the car would slow down as if I lifted by foot. Then the car would jerk and increase in speed again. There were no warning lights or messages at any of those moments. Due to concerning safety, I was driving to the shop to have it evaluated when I broke down at a stop light. 5 minutes before breaking down, the first light came on with a message in the Ford app stating "powertrain malfunction". When at a light, the automatic break kicked on and would not let me drive. When evaluated at the local dealership they said "there are multiple DTCs for internal transmission issues: DTC P0751/P2700 for a clutch mechanical fault, and P07E4 indicating the vehicle is unable to engage park. The A clutch is dragging, causing it to intermittently creep forward in neutral. The transmission will need to be replaced to correct the issue." The cost to replace it is $10,000+.

My wife's 2021 Ford Bronco Sport has had a complete transmission failure and the vehicle has less than 75,000 miles on it. We're told by Ford that the Powertrain warranty ends after 60,000 miles. This has been a disaster for us as we're paying a note on a vehicle that we cannot drive because it will cost $10-11K to repair. I've never owned a vehicle that has had so many problems in my life.

I was driving home from work one day on a Monday and my vehicle had a bunch of warning notifications pop up such as pre collision assist not available, blind spot assist not available, etc as well as a wrench icon popped up and stayed on stating to service 4wd. I stopped driving my vehicle until I could get it serviced. I then took my vehicle to ford to get it diagnosed on Friday of the same week ford stated they would be able to diagnose it for $150 then repair and labor costs would come after. Well they never looked at my vehicle Friday so they told me to bring it back the next Monday I brought it back they said they would diagnose it a few hours later I received a call stating they “think” it’s my AWD module located under the passenger seat but they would not know if that was the problem until they got under the seat and that would cost me an extra $500 for them to inspect it. From research I have been doing they should have been able to tell me if it was exactly that module or not by plugging a J2534 into the main module and using the FDRS application that all ford dealers use. From more research I have been doing this is a very common problem with 2021 ford broncos concerning the AWD module. The faulty AWD module could be caused from a faulty battery which was a recall on my specific vehicle they stated they tested my battery that day but I’m not sure if they actually did because I tested it at home and it was reading low and I just had that battery replaced by ford in March of 2025. As well a faulty AWD module in a 2021 Bronco Sport could be related to a recall, especially the recall for the powertrain control module (NHTSA Campaign 25S26) which can cause AWD system faults. Additionally, there was a separate, earlier recall (Customer Satisfaction Program 21B19) specifically addressing a faulty transistor in the AWD module itself. My car is was not a candidate for this recall but I believe it is apart of it as well as others who are experiencing this problem.

My 2021 Ford Bronco Sport Big Bend 1.5L EcoBoost (VIN: [XXX] ) suffered a turbocharger failure due to oil leakage, which caused overheating and smoke from the engine bay. The vehicle became unsafe to drive due to loss of power and risk of fire from leaking oil near hot engine components. I’ve found numerous reports online of similar failures in other 2021–2022 Bronco Sport 1.5L models, suggesting a possible design or component defect. This issue poses a serious safety concern, as the engine can overheat or lose power suddenly while driving, increasing the risk of crash or fire. Please investigate this matter to determine if a recall or safety campaign should be initiated to address recurring turbocharger and oil leak failures in these vehicles.
