Open-data reference.
NHTSA Complaint about SUSPENSION:FRONT:SPRINGS:LEAF SPRING ASSEMBLY:U-BOLT, LEAF SPRING TO AXLE filed September 16, 2021
NHTSA complaint #1768698 (ODI reference 11433225) concerns a 2004 HUMMER H2 and was filed on September 16, 2021. The owner reports the failure occurred on August 15, 2021. The vehicle had 100,000 miles on the odometer at the time of the incident. The report was geocoded to Alaska based on the filer's self-reported location. The affected component is categorized as suspension:front:springs:leaf spring assembly:u-bolt, leaf spring to axle, 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 HUMMER H2 cohort independently describe similar suspension:front:springs:leaf spring assembly:u-bolt, leaf spring to axle 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 2004 HUMMER H2 shows the complete component-level complaint distribution alongside any active investigations or recalls.
