On days when it rains or the weather is slightly cold/dewy, the Ford Bronco seems to make a screech/horn-like sound only when reversing. I found some online forum links (listed below) where other Ford users seem to describe the similar issue we're experiencing. This is the second dealership that we have taken the vehicle to be serviced for the issue, but they have both stated there is nothing they can do because the issue has not been issued as a recall. [XXX] [XXX] [XXX] The first dealership visited for service was: Metro Ford Sales & Service, Inc. Address: 6455 S Western Ave, Chicago, IL 60636 The second dealership visited for service was: Napleton Ford of Oak Lawn Address: Address: 6100 W 95th St, Oak Lawn, IL 60453 The attachment includes the most recent appointment visit. Unfortunately, I cannot provide an invoice at this time because the vehicle is still at the dealership (10 days after taking it in). I visited the dealership yesterday (08/12/2024) where I was informed that the the service technician working on my car is in the hospital. Had I not visited, then I probably would not have known this, and the other service technician I spoke to said they could not share any more details since they were not part of the servicing for my car. Martin Garcia (mgarc520@ford.com) is supposed to be the middle-man between me and the dealership to help me address the issue, but I have not received information from his end either. When I called the Ford's number using (866) 631-3788 to get a hold of Martin Garcia, someone else assisted and I was told that he would call me tomorrow (08/14/2024) to give him an update on what the dealership shared with me.

Loss of power. I was traveling after work and heading to family’s resident. I was on the freeway and noticed the engine light come on then followed by a loss of power. The slightest 1 degree difference incline had the vehicle lose 20-30 mph while on a highway of 65 mph limit. I turned around the it made every little climb dangerous to drive. Luckily I was heading back home while it was nearing midnight. The freeway was especially free of the normal traffic. Im glad I made it home safely but the slightest incline while on a 75 mph limit freeway was dangerous when I dropped to 35-40 mph. I took my vehicle in to the dealership. Upon a diagnosis, they found the solenoid to have short circuited. Last thing I heard today from the service advisor was the part needed is now on back order.

AWD Module tested internally bad when assessed by local dealership. Vehicle was taken in for assessment after a software update recal was completed as vehicle then started stating vehicle had a powertain malfuntion, Pre-collision system was off, Hill.assist was off, Traction control was off, 4WD unavaialble, AWD unavailable. The dealership AND Ford Customer Service states that this was not covered under the warranty as it was not a powertrain malfunction but rather and electrical issue. I researched and found Customer Satisfaction Program 21B19- AWD Module Replacement was filed with NHTSA ID Number: 10191184. Which has my vehicle make, model and year stating that there was in fact a known issue. I was never notified of this issue and am now being told my problem is only electrical and not covered under my warranty resulting in me having to pay out of pocket to correct a KNOWN problem that has been documented.

I recently had the recalls addressed (despite having any issues with the vehicle). Days later, I noticed my vehicle would occasionally not detect my key fob. Changed battery without resolution. On 6/27/24, I was driving in rush hour traffic, and stopped with the red light. When the light turned green, I went to drive, and the car shut itself down. Everything shut down. Couldn't even turn on my hazards. While waiting for a tow truck, I received a tip to use the key fob to push the start button, and that actually worked. I took it to Ford, and they returned it 12 days later with updated modules (they stated they couldn't diagnose the issue which is fascinating to me considering the nature of the recalls and all the information I am able to find online). 10 days after having it back, the vehicle hesitated to start and displayed a 4wd fault error. Contacted Ford immediately. The next morning, I started the car and the errors were gone, but I still wanted to get it checked out, so headed towards Ford. Stopped for gas on my way, but after filling up the tank, my car wouldn't start again. This time far worse than the first time, as something under the hood starting making a clanking noise, and smoke started coming out from under the hood, and smelled like electrical fire. The noise continued to get louder, and the smoke more violent. Finally cut the battery cable since the car was smoking, at the gas pump, on a busy Saturday, minutes before noon. Very scary situation, especially with kids in the car. We are OK. We are safe. But holy crap!

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.
