2024 KIA CARNIVAL — Complaint #2109796
Open-data reference.
NHTSA Complaint about Chest Clip, Buckle, Harness filed July 14, 2025
NHTSA complaint #2109796 (ODI reference 11673327) concerns a 2024 KIA CARNIVAL and was filed on July 14, 2025. The owner reports the failure occurred on July 12, 2025. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as chest clip, buckle, harness, 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 KIA CARNIVAL cohort independently describe similar chest clip, buckle, harness 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 2024 KIA CARNIVAL shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
My childâs seat buckles are still not locking into place. Iâve contacted Nuna and their response was they needed 24-48 hours to find a solution as Iâve already donât the seat recall solution. But they told me I canât use this seat for my child. So Iâm stuck without a car seat until they find some solution for me. I found this issue because my child was able to move the seat straps on his own, while I was driving down the highway.
