2021 HYUNDAI ELANTRA — Complaint #2154348
Open-data reference.
NHTSA Complaint about SEAT BELTS filed December 5, 2025
NHTSA complaint #2154348 (ODI reference 11703140) concerns a 2021 HYUNDAI ELANTRA and was filed on December 5, 2025. The owner reports the failure occurred on December 2, 2025. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as seat belts, 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 HYUNDAI ELANTRA cohort independently describe similar seat belts 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 2021 HYUNDAI ELANTRA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The horn is not working when I press the horn or on the key fob. I had it checked and the fuses were fine. The seat belt chime also does not work out of nowhere, same time the horn stopped working.
