Infiniti QX55 VIN Check

Which build runs owners report most

Characters 1–11 of a VIN identify the production run — plant, model year, body and engine — which splits the Infiniti QX55 into 10 distinct batches rather than one nameplate. On the Infiniti QX55 that distinction is not academic: its 10 runs average 1.2 complaints each, but the worst one — 3PCAJ5K34NF, a 2022 build — carries 2. That is 1.7× the model average, and the difference is invisible if you only look up the model name. The five runs at the top of this table hold 58% of every QX55 complaint on file.

Match the first eleven characters of your own VIN against these 10 runs. A hit means the fault reports below describe your exact build; no hit means yours sits among the 0 Infiniti QX55 runs that drew fewer reports than any listed here.

Which model years to check twice

Ranked by complaints per production run, not by raw count — a raw count only tells you which year sold well. Dividing by the number of runs strips the sales figures out and leaves the actual fault rate.

Heaviest year here is 2022 at 1.3 complaints per run; lightest is 2023 at 1. Treat the 2023 line with caution, though: complaints accumulate for a decade after a car is sold, so the newest Infiniti QX55 builds have barely started reporting.

What to inspect on this car

One system accounts for 43% of everything Infiniti QX55 owners report: Engine. Put it at the top of the inspection list — engine is where 6 of the 12 complaints on file landed, and a mechanic given a named part finds more than one told to «look it over».

Open recalls to verify

NHTSA has 2 recall campaigns on the Infiniti QX55, covering build years 2022 to 2023, and every one of them is free to fix at any franchised dealer, for the life of the car, whoever owns it now. The work only happens if someone books it, though — and a used car that changed hands may never have been brought in. Check each campaign below against your VIN.

The digits in a campaign number carry the year it was opened — «09V419000» means 2009. Compare that with the model years affected and you can see how long the fault ran before anyone acted on it.

How serious were they

A complaint count on its own is a weak signal — a rattling trim panel and a stalling engine both count as one. NHTSA records flag whether an incident involved a crash, a fire or an injury, and that is what separates annoyance from danger.

Crash-related reports run 100% below the all-vehicle rate — complaints here skew towards nuisance faults rather than dangerous ones.

How this check works

The file behind this page holds 1,109,349 complaints filed with NHTSA between 1981 and 2026, across 297,579 production runs. The Infiniti QX55 share of that is 12 complaints over 10 runs — 0% of everything on record. Each one carries the reporter's VIN prefix, the systems involved and whether the incident produced a crash, a fire or an injury.

Grouping those 10 runs by prefix is the whole point. Counted at model level the Infiniti QX55 averages 1.2 complaints per run, which hides the fact that one run carries 2 of them — a 1.7× difference the model name alone will never show you. We publish the eleven characters in full — they identify a batch, not a car, since the six-digit serial number naming the individual vehicle is not part of them.

Everything above is built from those 12 safety records and nothing else, so title brands, odometer readings, auction history and insurance write-offs are not in it — they live in DMV and insurer databases rather than NHTSA's, and no free tool has them, this one included.
