About Buick
Buick (a General Motors division) decodes through CheckMyVIN: model line (Enclave, Encore, Encore GX, Envision, Envista, and older LaCrosse / Regal / Verano / Lucerne), engine family, drive type, assembly plant (GM plants in Michigan and Tennessee, plus China for some crossovers), model year, and any open NHTSA recall — all pulled live from the official NHTSA VPIC database.
Founded 1903 and headquartered in Detroit, Michigan (General Motors), Buick vehicles register their VIN data with the National Highway Traffic Safety Administration (NHTSA). When you enter a Buick VIN above, CheckMyVIN queries the NHTSA VPIC database directly — pulling the same federally certified specs that the manufacturer reported when the vehicle was sold.
Buick uses several WMI codes (5GA, 1G4, LRB) depending on plant and model line — see the full Buick VIN Decoder for the complete table and a per-position walkthrough.
Where to find your Buick VIN
- Driver-side dashboard, near windshieldStand outside the vehicle on the driver's side and look at the corner of the dashboard where it meets the windshield. The 17-character VIN is engraved on a metal plate visible through the glass.
- Driver's door jamb stickerOpen the driver's door and look at the door jamb (the frame the door closes against). A federal certification label lists the VIN, tire pressures, and gross vehicle weight rating.
- Vehicle title, registration & insurance cardThe VIN appears on the title, current registration, and insurance documents. If buying used, cross-check the VIN on the car against every document — any mismatch is a major red flag.
What CheckMyVIN shows for Buick
Every Buick report includes the decoded specifications (engine, drive type, transmission, plant, body class), every open recall NHTSA has on file for the year/model/make combination, an AI-written plain-English summary, and the maintenance specs CheckMyVIN can confidently match by engine code. Tire sizes vary by trim and are always marked "Varies by trim — check door-jamb label" rather than guessed.
Common Buick issues to check before buying
Brand-specific known issues — useful as a pre-purchase inspection checklist. CheckMyVIN does not flag these per VIN; verify against service history.
3.6L V6 timing-chain wear
2008+ Enclave, LaCrosse and others with the GM 3.6L V6
GM's high-feature 3.6L V6 can stretch its timing chain, especially with neglected oil changes, setting cam/crank correlation codes (P0008/P0017-type) and a check-engine light. Listen for a cold-start rattle and check for stored codes; chain and guide replacement is labor-heavy. Documented, on-time oil changes are the best protection.
1.4L turbo (Encore) cooling & PCV / valve-cover issues
2013-2022 Encore and other 1.4L turbo Buicks
The GM 1.4L turbo four is prone to coolant leaks (water-outlet housing, hoses) and PCV / valve-cover diaphragm faults that cause rough idle, oil consumption, or a check-engine light. Check for coolant residue and confirm the car idles smoothly; these are common, moderate-cost repairs on higher-mileage Encores.
Side-airbag wiring & Takata-era airbag recalls
2008-2013 Enclave (side-airbag wiring) and various older Buicks
The first-generation Enclave (with GMC Acadia / Chevy Traverse) had a seat-side-airbag wiring recall (14V118000) that can prevent the side airbags and pretensioners from deploying. Some older Buicks also fall under broader airbag campaigns. Always run the VIN through the recall lookup and confirm any airbag campaign was completed.
Transmission & electrical (infotainment / electrical gremlins)
Various 2010+ Buicks
Higher-mileage Buicks can show transmission shift-quality complaints and assorted electrical/infotainment glitches (IntelliLink lag, sensor faults). On a test drive feel for smooth shifts and exercise the infotainment and driver-assist features; many issues are addressed by GM software updates at the dealer.
Buick buyer's notes
Buicks are quiet, comfortable, and generally affordable used, but check a few items. On 3.6L V6 cars (Enclave/LaCrosse), listen for timing-chain rattle and confirm oil-change history; on 1.4L turbo Encores, look for coolant leaks and PCV/valve-cover symptoms. Confirm model-specific recalls are closed — the 2008-2013 Enclave side-airbag wiring (14V118000) and the 2020 Enclave fuel-pump (20V639000) campaigns among them. The paint code and build options are on the GM RPO/SPID label (glovebox/trunk), not the VIN. China-built Buicks (Envision) are normal and fully US-titled. A GM/Buick dealer can pull the full service and RPO history from the VIN. Decode the VIN first to confirm the exact engine, drive type, and plant before negotiating.
Frequently asked questions
Which Buick models does CheckMyVIN decode?
Every US-market Buick in NHTSA VPIC: the Enclave, Encore, Encore GX, Envision, and Envista crossovers, plus older sedans (LaCrosse, Regal, Verano, Lucerne, Century, LeSabre, Park Avenue) and SUVs (Rendezvous, Rainier). Enter any 17-character Buick VIN and the report returns model, trim, engine, plant, year, and recalls.
Is Buick part of GM?
Yes — Buick is one of General Motors' four current US divisions, alongside Chevrolet, GMC, and Cadillac. They share GM platforms, engines, and WMI structure, so a Buick decodes much like its GM siblings — but a Buick VIN returns Make = BUICK in NHTSA VPIC.
Where is the Buick VIN located?
Driver-side dash at the base of the windshield (visible from outside), the driver door-jamb certification sticker, and on the title / registration. GM also prints an RPO/SPID option label (often in the glovebox or trunk) that lists the build option codes.
Are some Buicks built in China?
Yes — Buick is a major brand in China, and some US-market models (notably the Envision, and the Encore GX from Korea) are imported. VPIC returns the actual Plant Country; China-built Buicks start with LRB. The Enclave and older sedans are US-built.
Does this work for older Buicks (LaCrosse, Lucerne, Century, Park Avenue)?
Any 17-character Buick VIN (1981 onward) decodes through NHTSA VPIC — LaCrosse, Lucerne, Regal, Verano, Century, LeSabre, Park Avenue, Rendezvous, and Rainier included.
How do I check Buick recalls?
CheckMyVIN queries the NHTSA recall API live on every report (GM files Buick campaigns under General Motors). Notable examples include an Enclave side-airbag wiring recall and a fuel-pump recall. See the Buick recall page, then run your VIN.
How do I find the Buick paint code or build options?
They are not in the VIN — GM stores them on the RPO/SPID label (glovebox / trunk), not in the VIN characters. See the decoder FAQ below for how to read that label.
