Buick Enclave VIN Decoder
Decode any Buick Enclave VIN free in seconds. Type the 17-character vehicle identification number into the decoder above and pull the generation, model year, engine, trim, plant of origin, and open NHTSA recalls. No account, no credit card, no email gate.
This page goes deeper than the general Buick hub. Below you’ll find the Enclave’s three generations and the platforms under them, the single WMI the model has used since launch, a position-by-position guide verified against real decoded VINs (including where the engine code actually lands), trim levels by generation, and the Enclave-specific recalls worth checking.
About the Buick Enclave
The Enclave arrived in April 2007 as a 2008 model, Buick’s first three-row crossover and the vehicle that, alongside the GMC Acadia and Saturn Outlook, launched GM’s Lambda platform. It has always shared its bones with the Chevrolet Traverse. Three generations so far:
| Generation | Years | Platform | Built at |
|---|---|---|---|
| 1st | 2008-2017 | GM Lambda | Lansing Delta Township, Michigan |
| 2nd | 2018-2024 | GM C1XX (long-wheelbase variant, 120.9-inch wheelbase) | Lansing Delta Township, Michigan |
| 3rd | 2025-present | GM C1 (long-wheelbase variant) | Lansing Delta Township, Michigan |
The second generation, which went on sale in fall 2017, is also where Buick introduced the Avenir badge to an SUV for the first time, its second application anywhere after the 2017 LaCrosse. The third generation is a genuine ground-up redesign rather than a facelift: styling borrows from the Wildcat EV concept, the interior gets a 30-inch curved display, and the long-serving naturally aspirated 3.6-liter V6 is gone entirely, replaced by a single turbocharged 2.5-liter four-cylinder across every trim. Every Enclave built since 2007, across all three generations, has come from the same factory: Lansing Delta Township. It is the only Buick assembled in the United States.
Buick Enclave WMI codes (positions 1-3)
The first three characters, the World Manufacturer Identifier (WMI), are assigned by SAE International and confirmed against NHTSA’s public vPIC database. Every genuine Enclave VIN, from a 2008 CX to a 2025 Avenir, starts the same way:
| WMI | Country of build | Vehicle type |
|---|---|---|
| 5GA | USA | Buick Enclave, built at Lansing Delta Township, Michigan (all generations, 2008-present) |
Because the Enclave has never been built anywhere but Lansing, this is the only WMI you’ll ever see on a real one. A VIN claiming to be an Enclave that starts with anything else, including Buick’s passenger-car WMI 1G4, is either mislabeled or not actually an Enclave. Decode the full VIN with the tool above to confirm.
How to decode a Buick Enclave VIN, position by position
Positions 1-3: World Manufacturer Identifier
Covered above. Since every Enclave comes from one US plant, position 1 is always 5 (United States) and the full WMI is always 5GA, regardless of model year or generation.
Positions 4-8: Vehicle Descriptor Section (VDS)
This is where honesty matters more than a tidy table. Across real Enclave VINs decoded through NHTSA vPIC, positions 4 and 5 vary (we’ve confirmed both EV and KV, and ER, on genuine, checksum-valid VINs of the same trim and body style) without lining up cleanly to a single readable trim code the way some brands’ platform letters do. GM uses these characters, along with position 7, to encode body style and restraint configuration together, and that combination doesn’t reduce to a simple lookup table you can read by eye. If you want the exact body style and restraint system, use the decoder above rather than guessing from positions 4 to 7.
Position 8, however, is consistent and maps directly to the engine. Verified against real decoded VINs spanning 2008 through 2025:
| Char | Engine | Generation / years |
|---|---|---|
| 7 | 3.6L V6 (LY7) | 1st gen, early production (2008-2009) |
| D | 3.6L V6, flex-fuel (LLT) | 1st gen, later production (circa 2009-2017) |
| W | 3.6L V6 (LFY) | 2nd gen (2018-2024) |
| S | 2.5L turbo I4 (LK0), 328 hp / 326 lb-ft | 3rd gen (2025-present) |
That last row is the biggest single powertrain change in the Enclave’s history: the 3.6-liter V6 that powered every Enclave for 17 years was retired for 2025 in favor of a smaller, more powerful turbo four paired with an 8-speed automatic (the outgoing V6 used a 9-speed).
Position 9: Check digit
Calculated from the other 16 characters using SAE’s weighting formula and modulo-11 math. Mistype a single character anywhere in the VIN and this math no longer checks out; NHTSA’s database, every state DMV, and this decoder will flag the VIN as invalid rather than silently accepting a typo.
Position 10: Model year
The 10th character maps to a model year on a 30-year cycle, standard across the entire industry:
| Char | Year | Char | Year |
|---|---|---|---|
| R | 2024 | F | 2015 |
| S | 2025 | E | 2014 |
| T | 2026 | D | 2013 |
| V | 2027 | C | 2012 |
| W | 2028 | B | 2011 |
| X | 2029 | A | 2010 |
| Y | 2030 | 9 | 2009 |
| 1 | 2031 | 8 | 2008 |
| 2 | 2032 | 7 | 2007 |
| 3 | 2033 | 6 | 2006 |
The letters I, O, and Q are never used in any VIN because they look too similar to the digits 1 and 0. Since the Enclave launched for model year 2008, every Enclave VIN you’ll encounter uses character 8 or later on this cycle; you’ll never see a 7 (2007) or earlier on a genuine Enclave.
Position 11: Assembly plant
A single character identifies the specific factory. On every real Enclave VIN we decoded, from a 2008 CXL to a 2025 Avenir, this character reads:
| Char | Plant | Notes |
|---|---|---|
| J | Lansing Delta Township, Michigan | The only plant that has ever built an Enclave, across all three generations |
Unlike most models, there’s no second row here to add. The Acadia and Traverse, the Enclave’s Lambda/C1XX/C1 siblings, have picked up other plants over the years; the Enclave never has.
Positions 12-17: Serial number
The final six characters are the production sequence number stamped on your specific Enclave as it rolled off the line. Combined with the previous 11 characters, this makes every Enclave VIN globally unique, even for two cars built the same day at the same plant.
Enclave trim levels and how they show up in the VIN
The VIN doesn’t spell out trim by name; it’s reconstructed from the VDS block plus the factory build sheet, which is what the decoder above does for you. Confirmed trim ladders by generation:
- 1st gen (2008-2017): CX, CXL (early years); Convenience, Leather, Premium (later years, added with the 2011 update)
- 2nd gen (2018-2024): Preferred, Essence, Premium, Avenir (Avenir added for launch year 2018 as the range-topping trim)
- 3rd gen (2025-present): Preferred, Sport Touring, Avenir
Where to find the VIN on a Buick Enclave
- Lower-left corner of the windshield, visible from outside the vehicle
- Driver’s side door jamb sticker (also lists paint, tire, and option codes)
- Stamped on the engine block or front frame rail under the hood
- Vehicle title, registration, insurance card, and the Buick Owner Center app
The windshield and door jamb are the fastest checks on a used-car lot. The engine and frame stamps matter if you suspect a title has been swapped between two vehicles, since they’re tied to the chassis rather than a removable label.
Buick Enclave recalls and safety
Several Enclave-specific NHTSA campaigns are worth checking regardless of generation:
- Seat belt cable fatigue (2009-2014, built April 2008 through May 2014): The flexible steel cable connecting the seat belt to the front outboard seats could fatigue and separate over time, letting the belt fail to properly restrain the occupant in a crash.
- Windshield wiper linkage (2008 model year): GM recalled roughly 88,800 2008 Enclaves, along with 2007-2008 GMC Acadia and Saturn Outlook, over a wiper linkage issue.
- Driver air bag inflator, manufacturing defect (2008-2017): A manufacturing defect in the driver’s air bag inflator could cause it to explode during deployment, sending sharp metal fragments toward occupants.
- Frame rail crack (2020 model year): The right-hand frame rail in the engine compartment could crack, reducing crash performance.
- Roof-rail air bag inflator diffuser (2020 model year): The diffuser on the side-curtain air bag inflator might not have been properly crimped and could separate during deployment, degrading air bag performance.
To check your specific Enclave:
- Decode the VIN with the tool above to confirm the exact model year and generation
- Cross-reference the 17-character VIN with the Buick Owner Center recall lookup or NHTSA’s recall database
- Contact your nearest Buick dealer for any open campaign repair
Recall repairs are free regardless of the vehicle’s age, mileage, or ownership history.
Frequently asked questions
How do I decode a Buick Enclave VIN?
Type the 17-character VIN from the windshield, door jamb, or title into the decoder at the top of this page. Results return in seconds and include generation, model year, engine, trim, transmission, plant of origin, and open NHTSA recalls. No sign-up required.
Where is the VIN on a Buick Enclave?
The two fastest spots are the lower-left corner of the windshield, readable from outside the car, and the driver-side door jamb sticker, both federally required labels. The engine block and front frame rail carry a physical stamp matching the same number.
How do I tell which generation my Enclave is from the VIN?
Position 10 gives you the model year directly (see the table above), and that alone tells you the generation: 2008-2017 is first-gen, 2018-2024 is second-gen, and 2025-present is the redesigned third-gen. Position 8, the engine code, backs this up: 7 or D means a first-gen V6, W means a second-gen V6, and S means the third-gen’s turbo four-cylinder.
What changed with the 2025 Buick Enclave redesign?
The 2025 model year is a full ground-up redesign, not a refresh: new C1 platform, new Wildcat-inspired styling, a 30-inch curved interior display, and, most significantly for anyone reading a VIN, a completely different engine. The naturally aspirated 3.6-liter V6 used since 2008 is gone, replaced by a single turbocharged 2.5-liter four-cylinder making 328 horsepower across all trims.
Is the Buick Enclave VIN decoder really free?
Yes. VinDecoderPlus decodes every Enclave VIN free with no sign-up. The decode covers everything the factory stamped into the VIN. A full vehicle history report (accidents, odometer history, prior ownership, salvage status) is available as a paid upgrade if you need it.
Can a Buick Enclave VIN be faked?
The 17 characters can be reprinted on a counterfeit plate, but the check digit at position 9 catches most single-character changes through math, and the engine block or frame stamp is physically tied to the original vehicle. If the windshield and door-jamb VINs match but the underhood stamp doesn’t, treat the car as potentially cloned. The guide how to check if a car is stolen by VIN walks through the verification steps.
