2023 HYUNDAI SONATA — Complaint #2163954
Open-data reference.
NHTSA Complaint about POWER TRAIN filed January 7, 2026
NHTSA complaint #2163954 (ODI reference 11709400) concerns a 2023 HYUNDAI SONATA and was filed on January 7, 2026. The owner reports the failure occurred on January 6, 2026. The report was geocoded to Georgia based on the filer's self-reported location. The affected component is categorized as power train, 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 SONATA cohort independently describe similar power train 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.
Complaint Description
On January 6, 2026, during my morning commute in heavy traffic, my 2023 Hyundai Sonata engine unexpectedly turned off, causing a sudden loss of power. This created an extremely dangerous situation, and I came very close to being involved in a major collision. While I was fortunate to avoid a crash, the incident posed a direct threat to my safety and life because of the dense surrounding traffic.
