Open-data reference.
NHTSA Complaint about ENGINE filed September 8, 2025
NHTSA complaint #2128109 (ODI reference 11685755) concerns a 2025 FORD BRONCO and was filed on September 8, 2025. The owner reports the failure occurred on September 7, 2025. The report was geocoded to Arizona based on the filer's self-reported location. The affected component is categorized as engine, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same FORD BRONCO cohort independently describe similar engine failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2025 FORD BRONCO shows the complete component-level complaint distribution alongside any active investigations or recalls.

As soon as I turned around and descended approximately 100 feet in elevation the power came back instantly and vehicle operated normally. This happened on three occasions. The roads we were on were narrow, off-road vehicle mountain roads, and it created an extremely dangerous situation. I contacted Ford and they have not heard of this issue and there are no recalls associated with it. I spoke to a Ford bronco ambassador, who was also on the trail system with a lot of other off-road vehicles, including Broncos and they had never heard of this happening . This vehicle is Six months old. Ford says there are no codes set on my c
