Model-year matrix

Infiniti QX4
which year?

Compare every Infiniti QX4 model year the EPA recorded, 1997 to 2003. See complaint patterns, fuel economy and configurations side by side, then open any year for recall campaigns and the full dossier. Confirm against the official NHTSA recall search.

Evidence-led answer

Looking for the best Infiniti QX4 year—or years to avoid?

The official records cannot honestly name a best, worst or most reliable year. Complaint totals have no sales, mileage or age denominator. They can show where more reports were filed and which components were named, giving you years to investigate more closely before checking the exact car and its VIN.

What is the best year for the Infiniti QX4?

No official dataset can support one universal best year. Use the table to compare complaint patterns and EPA figures, then open the shortlisted years for recall campaigns and exact specifications.

Which Infiniti QX4 years should you avoid?

The records cannot justify a blanket avoid label. Years with more reports are surfaced below as research priorities, not predictions about every car from that year.

Do not read this as an avoid list. Older and higher-selling model years usually accumulate more reports. A low count can also mean a newer, rarer or poorly matched vehicle—not a safer one.

Read this as evidence, not a ranking.

Complaint totals are counts of owner-submitted allegations, not confirmed defects, and they carry no denominator: they are not adjusted for how many cars were sold, how old they are, how far they are driven, or how much publicity a fault received. A high-volume or older year will usually show more reports than a rare or recent one. The site does not convert these into a reliability score, because the data needed to do that honestly is not in the public record.

Direct comparison

Observed complaint-record difference

2003 has 17 fewer indexed complaint allegations than 2002.

This is not a rate or reliability finding. The counts have no sales, mileage, age or exposure denominator, and newer years have had less time to accumulate reports.

Side by side

Infiniti QX4 by year.

Complaint bars are scaled against this model’s own highest year, so they compare years with each other and with nothing else.

Evidence snapshot generated August 25, 2026. “Not indexed” means NHTSA holds no complaint record matching this exact year, make and model — not that no fault occurred. Recall campaigns are not summarised here: NHTSA publishes no bulk recall dataset, and fetching them per year would take longer than the page should. Each year’s dossier shows its recalls in full, live from NHTSA.
