2021 Ford Bronco Sport · Electrical & powertrain
Sudden 12-volt battery failure and loss of drive power
A sudden electrical blackout or failure to restart after an auto stop is the pattern addressed by Ford recall 25S02 on certain Bronco Sport vehicles.
What the reviewed source says
Start with the documented condition, not a parts guess.
Ford recalled certain 2021 to 2023 Bronco Sport vehicles after tracing abrupt 12-volt battery failures to internal weld or cast-on-strap defects in a specific supplier battery. The condition can prevent a restart after an auto stop or stall the vehicle as it comes to a stop. The recall is VIN specific, so a normally aging or discharged battery is not enough to identify this defect.

Manufacturer position
What the official procedure directs
Ford instructs dealers to inspect for a Ford AGM 12-volt battery and install the specified AGM replacement when one is not already present, at no charge under the recall.
Recall 25V-019 is tied to the installed battery and vehicle build record, not a published mileage threshold.

Repair paths and safe checks
Separate the diagnosis from the action.
VIN check and recall battery remedy
Ask a Ford dealer to check recall 25S02 against the VIN. The published remedy is to verify whether the specified Ford AGM battery is present and install it when required.
The earlier software recall 24S24 is not a substitute for the battery remedy when 25S02 is open on the VIN.

Record the failure without recreating it
Write down whether the event followed auto stop, which accessories failed and whether the vehicle restarted. Photograph any cluster message only after the vehicle is safely stationary.
Do not intentionally trigger auto stop to reproduce a previous loss of power.

Useful before authorizing work
Read the method beside the problem
These guides explain the safety and evidence checks that apply to this problem file.
Check recalls by VIN
A VIN search checks the displayed NHTSA records for an unrepaired safety recall associated with one vehicle. A model search shows only the wider campaign population.
Read guide ↗When a car is unsafe
A warning light does not always mean the same thing, but weak brakes or smoke leave little room for experimentation. Damaged tires and certain recall instructions can do the same.
Read guide ↗Why symptoms overlap
“It makes a weird noise” is useful human language. Diagnosis begins when that language is tied to the exact vehicle and its operating conditions.
