NHTSA complaint #2154334 (ODI reference 11703134) concerns a 2025 MAZDA CX-30 and was filed on December 5, 2025. The owner reports the failure occurred on December 4, 2025. The report was geocoded to Colorado based on the filer's self-reported location. The affected component is categorized as tires:pressure monitoring and regulating systems, 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 MAZDA CX-30 cohort independently describe similar tires:pressure monitoring and regulating systems failures, defect investigators have grounds to open a PE and request manufacturer data.
