NHTSA complaint #2049336 (ODI reference 11631487) concerns a 2021 FORD F-550 SD and was filed on December 18, 2024. The owner reports the failure occurred on October 31, 2024. The vehicle had 101,000 miles on the odometer at the time of the incident. The report was geocoded to Illinois based on the filer's self-reported location. The affected component is categorized as power train:axle assembly:axle shaft, 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 F-550 SD cohort independently describe similar power train:axle assembly:axle shaft 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 2021 FORD F-550 SD shows the complete component-level complaint distribution alongside any active investigations or recalls.
