2014 HYUNDAI SONATA — Complaint #1784593
Open-data reference.
NHTSA Complaint about ELECTRICAL SYSTEM:12V/24V/48V BATTERY:CABLES filed December 23, 2021
NHTSA complaint #1784593 (ODI reference 11444844) concerns a 2014 HYUNDAI SONATA and was filed on December 23, 2021. The owner reports the failure occurred on December 14, 2021. The vehicle had 50,100 miles on the odometer at the time of the incident. The report was geocoded to Pennsylvania based on the filer's self-reported location. The affected component is categorized as electrical system:12v/24v/48v battery:cables, 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: yes, 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 electrical system:12v/24v/48v battery:cables 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 2014 HYUNDAI SONATA shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2014 Hyundai Sonata. The contact stated that the accelerator pedal was depressed while he was at a complete stop at the stoplight, but it failed to respond. The battery warning light and several unknown warning lights were illuminated. The contact turned off and attempted to restart the vehicle however, the vehicle would not start. The contact noticed smoke coming from underneath the driverâs side hood. The contact was able to push the vehicle to the side of the road with some assistance. The vehicle was towed to the dealer who diagnosed that the engine had seized and needed to be replaced. The manufacturer was made aware of the failure and a case was opened. The manufacturer called the contact and advised that he would be responsible for the cost of the repair as he failed to complete an unknown recall repair. The vehicle was not repaired.
