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.

I currently am at 14,000 miles on my2021 Bronco Sport. I have had no issues prior to what happened to me on August 9th. While I was at a light my car went completely black with no warning and I was not able to put on hazard lights or put it in neutral to get off the busy highway. I had to call 911 as cars were zipping up close to mine and I was only able to wave my arms to get them to see my car was unoccupied. I was screamed at, honked at all while frantic trying to explain to the 911 operator that I needed a deputy to come and put his lights on behind my car to prevent an accident. My car sat in the middle of the highway with no warning lights on until a tow truck arrived. We then found out there is a way to release the gear and put it into neutral so we could push it to the side of the road. The car was towed to the house where I then had to have another tow truck come get it and tow it to the dealership where i was already waiting for a part. (Differential) At this point it has now been 8 days and i have no updates on what actually happened to my car but in my discovery I have read that this is a more common occurrence than not. Just while waiting in the Enterprise waiting room, waiting for my rental I met a girl with the same exact issue. How many others is this happening to and when will Ford recall this model car before someone is killed? I want answers and want to make sure when they say my car is fixed that it truly is fixed. I am scared to death to drive it now that I even have purchased road flares so I am ready for the next break down, because I truly believe it will happen again.

I originally reported it as possible CV joint issue. Dealer informed me it was a known issue and drained and replaced the RDU fluid. 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)

After coming down an incline in my garage at work I stopped at a red light, took my foot off of the brake to let the brake assist kick in and my auto idle kicked off as well. Within seconds my car shut off and the instrument panel started flickering. I got SEVERAL error messages flashing by quickly including the "Park Brake Malfunction Service Now" error. I tried to turn the car back on and kept hearing a clicking sound followed by all of the lights flashing again. I couldn't shift to any other gear and was stuck at this intersection unable to move the car or get the windows to open or do anything. Opened the hood to check the battery and everything looked clean and tightly connected. Jiggled the terminal and let it shut down completely. Tried starting again and it worked this time. This has happened once in this same spot before. I took it in to the dealership and they are currently "trying to recreate the issue to get the error message." The true safety concern is for this to happen while on the highway or even in the middle of an intersection. It seems to happen out of nowhere and the fact that the car cannot be put in neutral doesn't even allow for moving it to a safer location.

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. To review the reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.
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.

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.
