Safety instructions

Do not keep driving when…

Follow the owner's manual and the exact recall notice for immediate instructions.

  • The vehicle has stalled or failed to restart after an auto stop
  • Hazard lights or other essential electrical systems are unavailable
  • Electrical power is cutting in and out while the vehicle is running

What the source says

The documented condition

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.

Mileage context

Recall 25V-019 is tied to the installed battery and vehicle build record, not a published mileage threshold.

Official repair pathFord dealer · Inspection and battery replacement if required

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.

Boundary

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.

Boundary

Do not intentionally trigger auto stop to reproduce a previous loss of power.

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.

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.
