NHTSA complaint #463265 (ODI reference 10065133) concerns a 1999 GMC SUBURBAN and was filed on March 29, 2004. The report was geocoded to Tennessee based on the filer's self-reported location. The affected component is categorized as suspension:rear:springs:leaf spring assembly:hanger/bracket, 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 GMC SUBURBAN cohort independently describe similar suspension:rear:springs:leaf spring assembly:hanger/bracket failures, defect investigators have grounds to open a PE and request manufacturer data.
