NHTSA Complaint about VEHICLE SPEED CONTROL:ACCELERATOR PEDAL filed October 30, 2025
NHTSA complaint #2144438 (ODI reference 11696564) concerns a 2025 GMC SIERRA 1500 and was filed on October 30, 2025. The owner reports the failure occurred on February 1, 2025. The vehicle had 7,800 miles on the odometer at the time of the incident. The report was geocoded to Arizona based on the filer's self-reported location. The affected component is categorized as vehicle speed control:accelerator pedal, 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 vehicle speed control:accelerator pedal 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 2025 GMC SIERRA 1500 shows the complete component-level complaint distribution alongside any active investigations or recalls.
