A free VIN check on a Buick Somerset pulls up 7 owner complaints and 1 recall campaigns from NHTSA, spread across 6 production runs that average 1.2 complaints each. The spread is tighter than on most cars — the heaviest run carries 2, only 1.7× the typical Somerset — so on this one the model-level answer is closer to the truth. Characters 1–11 still tell you which run is yours.
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 Somerset into 6 distinct batches rather than one nameplate. On the Buick Somerset that distinction is not academic: its 6 runs average 1.2 complaints each, but the worst one — 1G4NM27U4GM, a 1986 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 86% of every Somerset complaint on file.
| Production run (VIN 1–11) | Year | Complaints | Involved a crash | Fire |
|---|---|---|---|---|
| 1G4NM27U4GM•••••• | 1986 | — | — | |
| 1G4NJ27L8FM•••••• | 1985 | — | — | |
| 1G4NM27L9FM•••••• | 1985 | — | — | |
| 1G4NJ27U5GM•••••• | 1986 | — | — | |
| 1G4NJ2712GM•••••• | 1986 | — | — | |
| 1G4NM27L36M•••••• | 1986 | — | — |
Match the first eleven characters of your own VIN against these 6 runs. A hit means the fault reports below describe your exact build; no hit means yours sits among the 0 Buick Somerset 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.
| Year | Per run | Complaints | Runs | Crashes |
|---|---|---|---|---|
| 1986 | 5 | 4 | — |
Heaviest year here is 1986 at 1.3 complaints per run; lightest is 1986 at 1.3. Every year listed is old enough to have finished collecting reports — the newest Buick Somerset here is a 1986.
What to inspect on this car
One system accounts for 29% of everything Buick Somerset owners report: Engine And Engine Cooling. Put it at the top of the inspection list — engine and engine cooling is where 2 of the 7 complaints on file landed, and a mechanic given a named part finds more than one told to «look it over».
| System | Complaints | Involved a crash | Fire |
|---|---|---|---|
| Engine And Engine Cooling | — | — | |
| Electrical System | — | — | |
| Exterior Lighting | — | — | |
| Seat Belts | — | — | |
| Tires | — | — | |
| Structure | — | — |
Open recalls to verify
NHTSA has 1 recall campaign on the Buick Somerset, covering build years 1985 to 1987, 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.
| Campaign | Component | Model years |
|---|---|---|
| 06E043000 | Fuel System, Gasoline | 1985–1987 |
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.
| Outcome | Buick Somerset | All vehicles |
|---|---|---|
| Complaints filed | 7 | 1,109,349 |
| Involved a crash | 0 (0%) | 63,931 (5.8%) |
| Involved a fire | 0 (0%) | 26,881 (2.4%) |
| Injuries reported | 0 | 57,747 |
| Deaths reported | 0 | 2,722 |
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 Buick Somerset share of that is 7 complaints over 6 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 6 runs by prefix is the whole point. Counted at model level the Buick Somerset 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 7 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.
Frequently asked questions
How do I check a Buick Somerset VIN for free?
Type the 17 characters into the box above. We match the first eleven — the production run — against 7 NHTSA complaint records and 1 recall campaigns for this model. No account, no card.
What does a free Somerset VIN check actually show?
For this model it is 7 complaints spread over 6 production runs, led by engine and engine cooling at 29% of all reports, plus every recall campaign and whether the incidents involved crashes or fires. What it cannot show is title brands, odometer readings or accident claims — those sit in DMV and insurer databases, not in NHTSA's.
Which Somerset years have the most complaints?
Per production run, 1986 is heaviest at 1.3 complaints per run. Judging by raw totals instead would just point at whichever year sold best.
Is a Somerset VIN check the same as a history report?
No. A history report (Carfax, AutoCheck) buys DMV title records, auction listings and insurance claims for one car. This is a federal safety check, and it answers a question those reports never ask: how your build compares with the other 5 Somerset runs on record, where the gap between the worst and the typical one runs to 1.7×. Both are worth having; only one of them is free.
Can someone identify my Somerset from these VIN prefixes?
No. The eleven characters shown identify a production batch — plant, year, body, engine — and that batch covers thousands of cars, which is why 1G4NM27U4GM above carries 2 separate reports. The six digits naming an individual vehicle are the serial number, and they are not part of what we publish.
