2020 INFINITI QX50 — Complaint #2128185
Open-data reference.
NHTSA Complaint about POWER TRAIN filed September 8, 2025
NHTSA complaint #2128185 (ODI reference 11685805) concerns a 2020 INFINITI QX50 and was filed on September 8, 2025. The owner reports the failure occurred on August 1, 2021. The report was geocoded to California 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.
Complaint Description
The vehicle's engine light turned on. The engine light remains on, and frequently the Malfunction and System fault See Owners Manual will display. When the malfunction message appears all the traction lights are also turned on. The RPM's in the vehicle are very accelerated, and it's difficult to drive the vehicle. The vehicle will also produce a very heavy smog smell. I took the vehicle into the retailer several times and nothing was done. The manufacturer is also not taking responsibility and stated the issue is unrelated to the engine bearing recall.
