2015 HYUNDAI SONATA — Complaint #2174638
Open-data reference.
NHTSA Complaint about ENGINE filed February 7, 2026
NHTSA complaint #2174638 (ODI reference 11716496) concerns a 2015 HYUNDAI SONATA and was filed on February 7, 2026. The owner reports the failure occurred on January 23, 2026. The report was geocoded to Virginia based on the filer's self-reported location. The affected component is categorized as engine, 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 engine 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 2015 HYUNDAI SONATA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
I have been dealing with issues with the turbo that cost over $3k out of pocket to get "fixed" only to have a part go bad and needed to be replaced. Now the engine is bad and needs to be replaced. The dealership is horrible at being honest and treat me as if that's not my only vehicle. I ask for a loaner car and thery never respond!!
