NHTSA Complaint about ELECTRICAL SYSTEM:SEAT HEATER:WIRING HARNESS filed August 31, 2021
NHTSA complaint #1766010 (ODI reference 11431242) concerns a 2020 CHEVROLET SILVERADO 1500 and was filed on August 31, 2021. The owner reports the failure occurred on November 28, 2020. The vehicle had 5,000 miles on the odometer at the time of the incident. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as electrical system:seat heater:wiring harness, 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: 1, 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 CHEVROLET SILVERADO 1500 cohort independently describe similar electrical system:seat heater:wiring harness failures, defect investigators have grounds to open a PE and request manufacturer data.
