NHTSA complaint #375569 (ODI reference 567316) concerns a 1996 GMC SIERRA and was filed on September 25, 2002. The owner reports the failure occurred on April 29, 2002. The report was geocoded to Connecticut based on the filer's self-reported location. The affected component is categorized as exterior lighting:back up lights:switch, 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 GMC SIERRA cohort independently describe similar exterior lighting:back up lights:switch failures, defect investigators have grounds to open a PE and request manufacturer data.
