NHTSA Complaint about FORWARD COLLISION AVOIDANCE: WARNINGS filed October 27, 2025
NHTSA complaint #2143561 (ODI reference 11695954) concerns a 2025 GMC SIERRA 1500 and was filed on October 27, 2025. The owner reports the failure occurred on February 20, 2025. The report was geocoded to Florida based on the filer's self-reported location. The affected component is categorized as forward collision avoidance: warnings, 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 GMC SIERRA 1500 cohort independently describe similar forward collision avoidance: warnings failures, defect investigators have grounds to open a PE and request manufacturer data.
