2025 MAZDA CX-70 — Complaint #2170089
Open-data reference.
NHTSA Complaint about LANE DEPARTURE: BLIND SPOT DETECTION filed January 26, 2026
NHTSA complaint #2170089 (ODI reference 11713459) concerns a 2025 MAZDA CX-70 and was filed on January 26, 2026. The owner reports the failure occurred on October 16, 2024. The vehicle had 2,500 miles on the odometer at the time of the incident. The report was geocoded to Nevada based on the filer's self-reported location. The affected component is categorized as lane departure: blind spot detection, 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-70 cohort independently describe similar lane departure: blind spot detection 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 MAZDA CX-70 shows the complete component-level complaint distribution alongside any active investigations or recalls.
