Open-data reference.
NHTSA Complaint about CHILD SEAT filed December 16, 2025
NHTSA complaint #2157687 (ODI reference 11705284) concerns a 2025 TOYOTA GRAND HIGHLANDER and was filed on December 16, 2025. The owner reports the failure occurred on November 1, 2025. The report was geocoded to Missouri based on the filer's self-reported location. The affected component is categorized as child seat, 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 TOYOTA GRAND HIGHLANDER cohort independently describe similar child seat 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 2025 TOYOTA GRAND HIGHLANDER shows the complete component-level complaint distribution alongside any active investigations or recalls.
