GarageCalc What the data says
Electrical system accounts for about 18% of this year's Infiniti Qx80 complaints. Complaints are spread across several areas, which reads more like normal ownership noise than a single defect.
The 2017 model year contributes 4 complaints (18%). Older vehicles dominate, consistent with age-related wear rather than a new defect.
Not enough 2025 complaints to compute a year-over-year trend (8 in the same window last year). Year-over-year movement is the most useful signal here: a model's sales are roughly stable from one year to the next, so a sharp rise means the per-vehicle complaint rate genuinely moved, not just that the model is popular.
How to read this
Raw complaint totals track how many Infiniti Qx80s are on the road as much as they track quality, so a high count on a best-seller is partly a volume story. Complaints are also self-reported: they capture what owners chose to file, not a controlled survey. Use these numbers to know where to look during a pre-purchase inspection and which recalls to check, not as a verdict on their own.

Frequently asked questions
Is the Infiniti Qx80 reliable?
Complaint counts alone cannot answer that, because they track how many are on the road as much as build quality.

Treat it as a starting point and cross-check recalls and a pre-purchase inspection for the specific vehicle.
