Buick Riviera 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 Buick Riviera into 136 distinct batches rather than one nameplate. On the Buick Riviera that distinction is not academic: its 136 runs average 1.8 complaints each, but the worst one — 1G4GD221XS4, a 1995 build — carries 10. That is 5.6× 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 17% of every Riviera 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 124 Buick Riviera 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 Buick Riviera the spread between build years is 2.3×: a 1995 car draws 2.3 complaints per run, a 1999 one 1. Same badge, same factory in most cases — different year.

Heaviest year here is 1995 at 2.3 complaints per run; lightest is 1999 at 1. Every year listed is old enough to have finished collecting reports — the newest Buick Riviera here is a 1999.

What to inspect on this car

One system accounts for 16% of everything Buick Riviera owners report: Service Brakes. Put it at the top of the inspection list — service brakes is where 36 of the 246 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 17 recall campaigns on the Buick Riviera, covering build years 1984 to 1996, 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. Of the 246 reports on the Buick Riviera, 4.9% involved a crash against 5.8% across all vehicles — below the norm, and that ratio matters more than the raw total.

Severity tracks close to the all-vehicle average — the mix of trivial and serious reports is unremarkable.

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 Buick Riviera share of that is 246 complaints over 136 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 136 runs by prefix is the whole point. Counted at model level the Buick Riviera averages 1.8 complaints per run, which hides the fact that one run carries 10 of them — a 5.6× 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 246 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.
