2020 INFINITI QX50 — Complaint #2178470
Open-data reference.
NHTSA Complaint about POWER TRAIN filed February 19, 2026
NHTSA complaint #2178470 (ODI reference 11719065) concerns a 2020 INFINITI QX50 and was filed on February 19, 2026. The owner reports the failure occurred on January 19, 2026. The report was geocoded to New York 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
I am a [XXX] woman who purchased my first vehicle on December 6, 2024, with 43,000 miles. I have driven fewer than 20,000 miles since purchase, and the vehicle currently has approximately 62,000 miles. Until January 19, 2026, I experienced no issues. I have properly maintained the vehicle and followed all recommended service guidelines. I completed three oil changes during my ownership, averaging approximately every 8,500 miles. Two oil changes were performed by a licensed mechanic, and the most recent oil change and inspection were completed on November 29, 2025 at Legend Infiniti. I have receipts for all services. On January 19, 2026, while driving approximately 65 mph on a four-lane highway in Long Island, the vehicle suddenly went into limp mode and dropped to about 10 mph without warning. This created an extremely dangerous situation with a serious risk of collision. I first brought the vehicle to my mechanic, who advised me to take it to an authorized Infiniti dealership due
