I am currently on my Third battery. Prior to getting this third car battery, there was numerous electrical issues randomly occurring. I read that there is a current investigation going on with Bronco Sports just stopping, could it be batteries failing and not being g detected?? Just wanted you to know. The first time I had dealership replace battery, they said it tested "fine" I had to insist something be done, which led them to try replacing the original battery. Since it's happened before the dealership just replaces the batteries and then stuff works normally. Can't recall dates off hand, but at home I have paperwork with dates.

My 2021 Bronco failed our family on Friday. The Bronco failed to start upon pressing the start and brake pedal. The main console panel started flashing then cycling through all kinds of failure alerts. There was a series loud noises from the engine, the headlights flashed off and on for over 3 minutes and then the engine started smoking. The doors would not open and we were stuck inside while the engine was smoking. That smoke came through the air vents as well. Finally, I was able to get my door open though couldn’t open my son’s rear passenger side door from the outside. He was stuck inside for what seemed like forever. He was able to open it finally and I carried him inside. My son’s legs are paralyzed and he does not walk. My main concern was getting him to a safe place as I was scared to death that the engine was going to explode in that moment. The engine smoke started to ease up however the electrical burning smell was overwhelming. This all took place in my garage. The trunk would not unlock and my key fob would not engage with the vehicle at all during this time. The trunk hatch lock finally disengaged and I was finally able to get his wheelchair out. Everything failed. I could not get the Bronco into neutral at any point. The Bronco is currently at my local Ford dealer where I was told I have to wait a week before it can even be looked at. I was told "it's just the battery...." There is NO way my experience was "just the battery." As of 10/10/2023 no one from corporate or the dealer has reached out to me. Once I got to the dealer (Jarret Gordon Ford Davenport), they were so dismissive of me. The service advisor never even asked if my son or myself were OK.

When reversing there is the absolute worst extremely loud embarrassing metallic screeching sound, considerable to a ships horn. Once you press brake fully and come to a complete stop the sounds ceases, let go of the brake it come right back. You can put it in drive and then back to reversing, same thing. Dealership was informed in 2022, said they fixed it. Spring/Summer of 2023 after complaining again was told part was ordered, could not be told what part. September 2023 was told no part was ordered, issue was fixed. October 2023 had a male take my bronco in for repairs and answers, parts are now reordered, parts are back ordered since this is a recall, no time frame on repair. When you check my vin for recalls, all recalls are closed. I am under the impression that my Dealership never has done recall work and only clearing them off as completed.

Since dec 2021, buying vehicle, I've not had real heat, you can turn heat to 86 and above and have heat, nothing in between. Was told they needed to speak to engineer to fix problem. I took it back in needing heat again, and was told if I only use automatic and set temperature, I could have a temporary solution for zero heat and they would find a more permanent solution. My vehicle is almost 2 years old and i still have not had an engineer diagnose and fix my heat. I've been told by dealership that temporary fix should be sufficient or to sell my bronco.

When trying to start the vehicle, it would not crank. Instead, all dash indicator lights, interior lights, and exterior lights began flashing. Numerous random error messages began flashing on the dashboard screen. Then a large plume of smoke began coming out from under the hood and there was an acrid burning smell. No flames were visible so the fire department would not respond when called and advised to have it towed. After much difficulty loading onto a tow truck (the parking brake would not disengage--dash indicated a parking brake fault as one of the many errors--so it had to be dragged onto the flatbed tow truck) the vehicle was towed to the local dealership in Dothan, AL. Per the dealership, there was an underhood fire involving the starter and battery. We are unable to inspect the damaged components. They stated they are unable to remedy the smoke smell that has permeated the vehicle despite the disabling lung conditions of one of our family members. We have tried numerous times over the last 9 months to get the dealership to perform service required by NHTSA Recall # 22V859, but they keep stating the parts are unavailable. They will not say whether this underhood fire is directly related to the recall already in effect.

Issue went away but resurfaced around the 50,000 mile mark. same results that the issue went away. Issue came once again at ~ 75,000 miles at which point I was informed that it was no longer covered by warranty. I paid to have same "fix" done, however the issue did not go away. Ford has stated that they will not cover cost of repair even though this is an existing issue identified under warranty and not corrected. Issue currently has a NHTSA communication (10187981)

2RQ24014 · Loss Of Motive Power
Opened Nov 15, 2024 · Closed Oct 10, 2025
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.
