Open-data reference.
NHTSA Complaint about VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM filed January 30, 2026
NHTSA complaint #2171516 (ODI reference 11714425) concerns a 2024 CHEVROLET SILVERADO EV and was filed on January 30, 2026. The owner reports the failure occurred on January 2, 2026. The vehicle had 13,000 miles on the odometer at the time of the incident. The report was geocoded to Maine based on the filer's self-reported location. The affected component is categorized as visibility:defroster/defogger/hvac system, 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 CHEVROLET SILVERADO EV cohort independently describe similar visibility:defroster/defogger/hvac system 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 2024 CHEVROLET SILVERADO EV shows the complete component-level complaint distribution alongside any active investigations or recalls.
