Buick VIN check · US vehicle history
Buick VIN check and vehicle history report
Buying a used Buick? Enter the 17-character VIN to decode the exact model, engine and plant, then open the car's history report: odometer readings, police-reported crashes, salvage and insurance auction records with photos, and NHTSA recalls, from all states, where available.
Works for every Buick with a 17-character VIN (model year 1981 and later), including the Encore GX, Envista, Enclave, Envision and Encore.
One report is $9.99. Carfax lists one report at $49.99 and carVertical at $34.99 on their US websites (checked Oct 24, 2026).
What a Buick VIN tells you
Most new Buicks sold in the US are imported: the Encore GX and Envista from South Korea (KL4) and the Envision from China (LRB). The Enclave is the one built in Michigan.
Buick shares engines and many recalls with Chevrolet and GMC models on the same platform (Enclave/Traverse, Encore GX/Trailblazer, Envista/Trax).
Buick WMI codes on US-market vehicles
The first three characters of the VIN are the World Manufacturer Identifier. They tell you who built the car and in which country, and they must match the brand on the title.
| WMI | Assembled in | What it covers |
|---|---|---|
| 5GA / 1G4 | United States | Enclave (5GA) and older sedans like LaCrosse (1G4) |
| KL4 | South Korea | Encore, Encore GX and Envista from Korea |
| LRB | China | Envision from China |
How to read the 17 characters of a Buick VIN
Every car sold in the US since model year 1981 follows the same 17-character layout (49 CFR Part 565). The letters I, O and Q are never used, so they cannot be confused with 1 and 0.
| Position | What it is | What it tells you |
|---|---|---|
| 1-3 | World Manufacturer Identifier | Maker and country of assembly, e.g. 5GA / 1G4 for Buick (United States). |
| 4-8 | Vehicle descriptor | Model, body, restraint system and, on most makes, the engine. |
| 9 | Check digit | A digit or X computed from the other 16 characters. If it does not compute, the VIN was mistyped or altered. |
| 10 | Model year | A letter or digit for the model year (table below). It is not the build date. |
| 11 | Plant | The Buick assembly plant that built the car. |
| 12-17 | Serial number | The production sequence that makes this car unique. |
Model year codes (10th character)
The model year often starts in the fall of the previous calendar year, so a car built in September 2025 can be a 2026 model. The codes repeat every 30 years: A was 1980 and again 2010.
| Code | Model year | Code | Model year | Code | Model year |
|---|---|---|---|---|---|
| A | 2010 | G | 2016 | N | 2022 |
| B | 2011 | H | 2017 | P | 2023 |
| C | 2012 | J | 2018 | R | 2024 |
| D | 2013 | K | 2019 | S | 2025 |
| E | 2014 | L | 2020 | T | 2026 |
| F | 2015 | M | 2021 | V | 2027 |

Known issues and recalls to ask about on a used Buick
Make-level problems that have been widely reported in the US. Whether a given car is affected depends on its model year, engine and repair history.
- Early Enclaves with the 3.6L V6 (around 2008-2012) are known for timing chain stretch; ask for timing chain service on high-mileage examples.
- Buicks are often bought by older owners and kept with low mileage, which also makes them attractive for odometer fraud. Compare the odometer with the dated readings in the report.
How to confirm a recall repair on this exact car
Our report lists the NHTSA safety recalls and owner complaints for the model and model year. Whether a specific repair was done is recorded per VIN by the manufacturer: enter the VIN at nhtsa.gov/recalls or ask any Buick dealer for the recall history before you buy. Safety recall repairs are normally done at no charge by a franchised dealer.

Where to find the VIN on a Buick
- On the driver side of the dashboard, readable from outside through the bottom of the windshield.
- On the label in the driver door jamb, next to the build month.
- On the title, the registration card and the insurance card. On pickups and body-on-frame SUVs it is also stamped on the frame.
- All of them must show the same 17 characters. If one does not match, stop and ask why before you pay.

Buick VIN check questions
Where is the VIN on a Buick?
On the driver side of the dashboard, visible through the windshield, and on the label in the driver door jamb. It is also printed on the title, the registration and the insurance card. All of them must match.
What do the first three characters of a Buick VIN mean?
They are the World Manufacturer Identifier (WMI): the maker and the country where the car was assembled. On Buick vehicles sold in the US you will see codes such as 5GA / 1G4 (United States: Enclave (5GA) and older sedans like LaCrosse (1G4)); KL4 (South Korea: Encore, Encore GX and Envista from Korea); LRB (China: Envision from China).
Why does my Buick VIN start with K or L?
Because it was built in South Korea (K) or China (L). The Encore, Encore GX and Envista come from Korea and the Envision from China; they are factory US-market cars.
How much does a Buick vehicle history report cost?
$9.99 for one report, $19.99 for three and $29.99 for five, paid once with no subscription and no account. Carfax lists one report at $49.99 on its US website. Records come from all states, where available.
How do I tell the model year of a Buick from the VIN?
Read the 10th character. For recent years: L is 2020, M 2021, N 2022, P 2023, R 2024, S 2025 and T 2026. The codes repeat every 30 years, so the model itself tells you which cycle you are in.
