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.

At 70K automatic transmission stated to cause jerking motions while in lower speeds when starting to drive from lower speeds. Took car to dealership and i need a new transmission. I have read on Bronco Forum from other Bronco Sport BADLANDS edition, that their transmission has failed too at various mileage, ranging from 30K-66K. Of course this is dangerous if there is a complete failure of transmission. FORD's warranty on power train ends at 36K. The cost is $8700 to replace. transmissions don't die at 70K. according to car experts, transmissions should last 120K-200K. I can't believe there is a recall for some Bronco Sports and not ALL Bronco Sports.

!!!ALWAYS GET A SECOND OPINION WITH "TRANSMISSION ISSUES"!!! I will NEVER get a Ford again! I'm updating my previous issue #11688946 I received my 2021 Ford Bronco Sport in early 2023. I noticed a shutter when accelerating from a stop, I took it to the dealership and had the 3rd fuel injector recall completed (still waiting for a remedy to the most recent #25V467). The dealership stated my vehicle should run fine now. The shutter persisted and worsened and a new issue developed, my RPM's would slightly bounce while going at a steady speed. 09/19/2025 BACK TO THE DEALERSHIP I GO!Just for them to "diagnose" the issue I had to pay $165.00. AND they tried to charge me double stating it took them 2hrs. My BS was dropped on less than 2hrs of them calling me. DIAGNOSIS: torque converter. They recommended a flush and fill for $300-$400. 09/25/2025 I bought an OBD-II and plugged in to see if there were any codes. The codes I got make way more sense than a new transmission. -U0140:00-08--BCM missing communication -U1A00:87-08--APIM private communication network malfunction -U2013:01-08-- Switch pack issue Also the EVAP system vapor pressure as well as Oxygen sensor current (B1-S1) is functioning incorrectly and randomly drops below the normal range. My transmission is fine... All they had to do is updated/reset my BCM when they had it as well as perform a "relearn". But they didn't!!! Clearly these are not always transmission issues but service work is what makes dealerships more money.

RDU (Rear Drive Unit) is beginning to I think fail and I have read on other forums with other people saying there’s failed and can be a safety risk. They are put at risk if the RDU fails while driving resulting in an accident. I haven’t gone to the dealership yet or let anyone else know. I thought doing a simple fluid change would do but it still persist. I’ve done research to understand what’s wrong. There was no warning lights but shuddering or grinding noise would occur and I believe it appeared a few hundred miles ago then go worse overall.

I own a 2021 Ford Bronco Sport that has had repeated premature failures of critical components. At ~52,000 miles the water pump failed and was replaced along with coolant and belts. Less than 21,000 miles later (at ~73,000 miles) the water pump has failed again, with coolant leakage and a burning coolant smell. Ford has issued TSB 23-2104 acknowledging coolant leaks at the water pump/hose connection, yet no recall or extended coverage has been offered. This is not the only issue. My alternator has also failed twice and required multiple replacements in under 4 years of ownership. Having two major components (water pump and alternator) fail repeatedly within such a short period clearly shows a systemic defect, not normal wear and tear. Safety risks: coolant leaks can drip or vaporize onto hot engine components, creating a fire hazard. Alternator failure risks sudden loss of power and stalling in traffic. Both are unacceptable in a vehicle this new. The dealership confirmed the latest water pump diagnosis and quoted over $1,000 in labor alone, placing an unreasonable financial burden on the owner. This is the second water pump and second alternator within 73,000 miles. Ford and its dealers know this is an ongoing issue in Bronco Sports, as confirmed by widespread owner reports and TSBs, but continue to deny responsibility. A recall or customer satisfaction program should be issued to address these repeated failures.

My Bronco sport started shuttering during acceleration as well as the RPM needle slightly bouncing up and down. I brought my Ford into the Ford dealership for a diagnosis, I paid $165 for them to look at it and them later tell me that my torque converter is going out. They recommended a flush and fill to help with the longevity, stating that would be between $300-$400. That's when I asked how much it would cost for them to fix the torque converter they stated between $3,500-$4,000. Really something I did not want to hear especially knowing that we are on our 15th recall but this one has no solution. Still waiting on the answers for recall #25S76 and #25V467.

Nothing was functional and we were unable to move the vehicle out of the street. A tow truck came in 3 hours and towed the vehicle to the dealership. The dealership advised that it was the battery which they replaced. When merging lanes on the interstate with oncoming traffic, the gas accelerator would not accelerate to speed up. I had to step all the way down on it several times until the vehicle was finally able to accelerate. This has also occurred while at a red light and stop sign.

Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery
On January 31, 2024, The Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE24002) to investigate loss of motive power allegations in model year (MY) 2021 Ford Bronco Sport vehicles. Consumers reported a loss of engine power accompanied by complete electrical system failure either while driving or after stopping at a traffic light or stop sign. The vehicles generally could not be restarted, and the incidents were commonly diagnosed by dealerships to a failed 12-Volt (12V) battery. On April 12, 2024, Ford issued safety recall 24V-267 covering 456,565 MY 2021-2024 Ford Bronco Sport and MY 2022-2023 Ford Maverick vehicles. The recall addressed loss of motive power resulting from sudden degradation of the 12V battery during the drive cycle. The recall remedy consisted of software updates to the body control module and the powertrain control module. The updated software aimed to provide warning to consumers when the battery is failing and inhibit certain vehicle functions which can lead to loss of motive power incidents. Additionally, Ford removed the existing 12V Enhanced Flooded Battery (EFB) as both a service component for the subject vehicles and original equipment for newly built Bronco Sport vehicles (during MY 2024 production), replacing it with a more robust absorbed glass mat (AGM) battery. The same AGM battery had been incorporated into Ford Maverick production in late 2022. Following recall 24V-267, ODI received loss of motive power complaints in vehicles that had previously received Ford’s software-based remedy. Consumers reported that they did not receive warnings related to the 12V battery or the vehicle’s electrical system before the loss of power. On November 15, 2024, ODI opened Recall Query (RQ24014) to assess the effectiveness of the 24V-267 recall remedy. On January 19, 2025, Ford issued recall 25V-019 covering 272,817 MY 2021-2023 Bronco Sport and MY 2022-2023 Ford Maverick vehicles. The new recall addressed the same hazard as 24V-267 but required replacement of the existing 12V battery with an AGM battery as the remedy. Ford reported that following the opening of RQ24014, it evaluated several field-returned 12V batteries, and determined that EFBs produced by battery supplier Camel potentially contained internal manufacturing defects causing loss of motive power. Ford further concluded that the software updates provided in the 24V-267 recall remedy were unable to detect battery failures quickly enough to avoid loss of motive power. Vehicles previously within the scope of recall 24V-267, but outside of the scope of recall 25V-019, are equipped with EFBs produced by a different battery supplier (Clarios). When recall 25V-019 was issued, Ford had not identified any Clarios EFBs exhibiting the same failure mode as the Camel EFBs. In light of Ford’s recall action, ODI is closing this Recall Query. The agency will continue to monitor loss of motive power complaints in Bronco Sport vehicles equipped with Clarios EFBs and reserves the right to take additional action if warranted by future circumstances.

PE24002 · Loss Of Motive Power
Opened Jan 31, 2024 · Closed Aug 19, 2024
Status: closed (inferred from source dates) · Electrical SYSTEM:12V/24V/48V Battery
On January 31, 2024, the Office of Defects Investigation (ODI) opened PE24002 to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco Sport vehicles. At that time, ODI had received 31 Vehicle Owner Questionnaires (VOQs), with consumers commonly reporting a loss of engine power accompanied by complete electrical system failure which occurred either while driving, or after coming to a stop. The investigation revealed that MY 2021-2024 Ford Bronco Sport and certain MY 2022-2023 Ford Maverick vehicles are equipped with a 12V enhanced flooded battery (EFB), which may experience an abrupt failure during a drive cycle. The failure is the result of an internal corrosion issue, which is influenced by long exposure to high under-hood temperatures. If the sudden loss of 12V battery voltage is not detected by the vehicle’s battery management sensor, the vehicle can experience a loss of power event without providing any warning to the driver. Following a loss of power due to battery failure, the vehicle may be without all 12V accessories including hazard lights and typically will not be able to be restarted. In its March 2024 response to ODI’s information request, Ford provided 367 customer complaints (including field reports, lawsuits, and legal claims) and 1005 warranty claims relating to the alleged defect. When combining ODI and manufacturer failure report data, there are 1,368 unique VINs represented across MY 2021-2023 Ford Bronco Sport vehicles. One of the VOQs submitted to NHTSA reported a minor rear-end collision resulting from a loss of power event. Included within Ford’s complaints were a reported single-vehicle collision and a vehicle fire which occurred following a loss of power event at a traffic light (fire cause and origin was not determined). Additionally, across ODI and manufacturer data, there were 12 allegations of either acid leaking from the 12V battery or smoke emitting from the battery area within the engine compartment. On April 12, 2024, Ford submitted recall 24V267 for MY 2021-2024 Ford Bronco Sport and certain MY 2022-2023 Ford Maverick vehicles (total population 456,565). The recall remedy provides updated calibrations to the body control module and powertrain control module. Ford indicated that the update will result in improved detection of 12V battery state of charge during drive cycles and will provide notification to the driver if the battery significantly degrades while driving. Additionally, Ford has replaced the EFB with an absorbed glass mat (AGM) battery as both a service component for the subject vehicles and as original equipment for Bronco Sport vehicles with production dates beginning in mid-March 2024. The warranty claim rate for peer vehicles equipped with an AGM battery is substantially lower than that for the subject vehicle population. In view of the recall action being taken by Ford, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.
