Kia Cadenza 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 Kia Cadenza into 60 distinct batches rather than one nameplate. On the Kia Cadenza that distinction is not academic: its 60 runs average 3.5 complaints each, but the worst one — KNALN4D74E5, a 2014 build — carries 15. That is 4.3× 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 29% of every Cadenza complaint on file.

Match the first eleven characters of your own VIN against these 12 runs. A hit means the fault reports below describe your exact build; no hit means yours sits among the 48 Kia Cadenza 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. On the Kia Cadenza the spread between build years is 9.5×: a 2014 car draws 9.5 complaints per run, a 2019 one 1. Same badge, same factory in most cases — different year.

Heaviest year here is 2014 at 9.5 complaints per run; lightest is 2019 at 1. Every year listed is old enough to have finished collecting reports — the newest Kia Cadenza here is a 2019.

What to inspect on this car

One system accounts for 27% of everything Kia Cadenza owners report: Engine. Put it at the top of the inspection list — engine is where 62 of the 208 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 6 recall campaigns on the Kia Cadenza, covering build years 2014 to 2020, 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. Take 21V137000 above: opened in 2021 on cars built from 2017 — 4 years of that fault on the road before anyone acted.

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. Of the 208 reports on the Kia Cadenza, 3.8% involved a crash against 5.8% across all vehicles — below the norm, and that ratio matters more than the raw total.

Crash-related reports run 34% 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 Kia Cadenza share of that is 208 complaints over 60 runs — 0.02% 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 60 runs by prefix is the whole point. Counted at model level the Kia Cadenza averages 3.5 complaints per run, which hides the fact that one run carries 15 of them — a 4.3× 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 208 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.
