2005 MERCURY MARINER — Complaint #552024
Open-data reference.
NHTSA Complaint about CHILD SEAT:HARNESS/CROTCH BUCKLE filed August 30, 2005
NHTSA complaint #552024 (ODI reference 10134747) concerns a 2005 MERCURY MARINER and was filed on August 30, 2005. The owner reports the failure occurred on August 5, 2005. The report was geocoded to Indiana based on the filer's self-reported location. The affected component is categorized as child seat:harness/crotch buckle, 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: yes, fire: no, injuries: 4, fatalities: 0. A complaint that flags a crash, fire, or fatality is escalated on NHTSA's internal review queue and factors more heavily into any Preliminary Evaluation decision on this make and model. 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 MERCURY MARINER cohort independently describe similar child seat:harness/crotch buckle 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 2005 MERCURY MARINER shows the complete component-level complaint distribution alongside any active investigations or recalls.
