2020 INFINITI QX50 — Complaint #1784287
Open-data reference.
NHTSA Complaint about POWER TRAIN filed December 21, 2021
NHTSA complaint #1784287 (ODI reference 11444616) concerns a 2020 INFINITI QX50 and was filed on December 21, 2021. The owner reports the failure occurred on December 21, 2021. The report was geocoded to Oregon based on the filer's self-reported location. The affected component is categorized as power train, 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 INFINITI QX50 cohort independently describe similar power train 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 2020 INFINITI QX50 shows the complete component-level complaint distribution alongside any active investigations or recalls.
