Open-data reference.
NHTSA Complaint about POWER TRAIN:AUTOMATIC TRANSMISSION:INTERNAL:SHAFT:OUTPUT filed October 18, 2021
NHTSA complaint #1774004 (ODI reference 11437160) concerns a 2013 FORD F-150 and was filed on October 18, 2021. The owner reports the failure occurred on October 15, 2021. The report was geocoded to Arizona based on the filer's self-reported location. The affected component is categorized as power train:automatic transmission:internal:shaft:output, 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-150 cohort independently describe similar power train:automatic transmission:internal:shaft:output 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 2013 FORD F-150 shows the complete component-level complaint distribution alongside any active investigations or recalls.
