Buick Terraza 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 Terraza into 86 distinct batches rather than one nameplate. On the Buick Terraza that distinction is not academic: its 86 runs average 2 complaints each, but the worst one — 5GADV33L05D, a 2005 build — carries 13. That is 6.5× 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 25% of every Terraza 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 74 Buick Terraza 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 Terraza the spread between build years is 2.6×: a 2005 car draws 2.9 complaints per run, a 2007 one 1.1. Same badge, same factory in most cases — different year.

Heaviest year here is 2005 at 2.9 complaints per run; lightest is 2007 at 1.1. Every year listed is old enough to have finished collecting reports — the newest Buick Terraza here is a 2007.

What to inspect on this car

One system accounts for 19% of everything Buick Terraza owners report: Electrical System. Put it at the top of the inspection list — electrical system is where 41 of the 175 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 4 recall campaigns on the Buick Terraza, covering build years 2005 to 2007, 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 175 reports on the Buick Terraza, 4.6% 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 Terraza share of that is 175 complaints over 86 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 86 runs by prefix is the whole point. Counted at model level the Buick Terraza averages 2 complaints per run, which hides the fact that one run carries 13 of them — a 6.5× 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 175 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.
