270 complaints owners filed with NHTSA about the Infiniti QX50 2016–2025, and the 1 system the record is deep on — engine (143). Each system has a page across the years; 1 model-year page goes deeper still. Every figure is a linked federal record; none is a failure rate or a verdict on one car.

Complaints owners filed with NHTSA naming each system, per model year; a bold count links the year’s own page on that system. Counts scale with sales and with time on the road; nothing here is a rate, and NHTSA’s headings are coarse (“Power Train” is the transmission and the driveline).
Common questions

Engine: 143 complaints across 9 model years, 53% of everything owners filed about the Infiniti QX50. A count, not a rate — it says nothing about how many were sold.
Which Infiniti QX50 year has the most complaints?
2019 (140), 2021 (40), 2020 (33). Older years have had longer to collect them; the year pages show each year's share by system.
