2023 HYUNDAI SONATA — Complaint #1924256
Open-data reference.
NHTSA Complaint about VEHICLE SPEED CONTROL filed September 1, 2023
NHTSA complaint #1924256 (ODI reference 11542119) concerns a 2023 HYUNDAI SONATA and was filed on September 1, 2023. The owner reports the failure occurred on August 18, 2023. The report was geocoded to Connecticut based on the filer's self-reported location. The affected component is categorized as vehicle speed control, 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: 0, 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 HYUNDAI SONATA cohort independently describe similar vehicle speed control 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 2023 HYUNDAI SONATA shows the complete component-level complaint distribution alongside any active investigations or recalls.
