NHTSA complaint #931771 (ODI reference 10468722) concerns a 2006 FORD F-550 SD and was filed on August 2, 2012. The owner reports the failure occurred on August 1, 2012. The report was geocoded to Connecticut based on the filer's self-reported location. The affected component is categorized as fuel system, diesel:storage:tank assembly, 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. No VIN was supplied by the filer, so this complaint contributes to model-year trend data but cannot be tied to a specific vehicle.

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 F-550 SD cohort independently describe similar fuel system, diesel:storage:tank assembly 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 2006 FORD F-550 SD shows the complete component-level complaint distribution alongside any active investigations or recalls.
