This page goes deeper than the general Buick guide. Below you’ll find the real chassis codes for both the original Encore and the newer Encore GX (they are two different models, not two names for one car), the WMI code that appears on every Encore VIN, a position-by-position breakdown with verified engine codes at position 8, the trims sold across each generation, and the Encore-specific recalls worth checking.
About the Buick Encore
The Encore launched for model year 2013 as Buick’s first small crossover, built by GM Korea at the Bupyeong plant in South Korea on GM’s Gamma II platform, shared underneath with the Chevrolet Trax and the Opel/Vauxhall Mokka. It ran as a single nameplate through the 2019 model year.
For model year 2020, Buick introduced a second, larger crossover called the Encore GX, built on GM’s newer VSS-F architecture (shared with the Chevrolet Trailblazer) and also assembled at Bupyeong. Buick did not replace the original Encore with the GX right away. The two models were sold side by side in US showrooms from 2020 through 2022, as genuinely separate vehicles with different platforms, engines, and VINs, not a base trim and an upgraded trim of one car. The original, smaller Encore was discontinued after 2022, leaving the Encore GX as Buick’s sole subcompact crossover today.
| Generation | Years | VIN code (positions 4-5) | Sold as | Platform | Built at |
|---|---|---|---|---|---|
| 1st | 2013-2022 | CJ | Encore | Gamma II | Bupyeong, South Korea |
| 2nd | 2020-present | MM | Encore GX | VSS-F | Bupyeong, South Korea |
That VIN code at positions 4-5 is the fastest way to tell the two apart when a listing is ambiguous. CJ is always the original, smaller Encore. MM is always the Encore GX. Decoding real, checksum-valid VINs through NHTSA’s vPIC database confirms this holds across both models’ full production runs, including the 2020-2022 overlap years when they were built side by side at the same factory.
Buick Encore WMI codes (positions 1-3)
The first three characters of a VIN are the World Manufacturer Identifier (WMI), assigned by SAE International on behalf of ISO. Every genuine Encore and Encore GX carries the same WMI:
| WMI | Country of build | Plant | Models |
|---|---|---|---|
| KL4 | South Korea | Bupyeong (GM Korea) | Encore (2013-2022), Encore GX (2020-present) |
Buick’s Envista, a newer subcompact SUV, also carries the KL4 WMI from the same plant, so the WMI alone will not tell you whether a KL4 VIN is an Encore, an Encore GX, or an Envista. You need the model code at positions 4-5 for that (see above). If an Encore VIN starts with anything other than KL4, treat it as suspect and decode the full string with the tool above.
How to decode a Buick Encore VIN, position by position
Every Encore and Encore GX ever built uses the 17-character ISO 3779 standard.
Positions 1-3: World Manufacturer Identifier
Covered above. KL4 means Korean-built GM product; on a genuine Encore or Encore GX, it will always read KL4, never a US or Chinese country code.
Positions 4-8: Vehicle Descriptor Section (VDS)
Positions 4-5 carry the model code, CJ for the original Encore or MM for the Encore GX. Position 8 is the engine code, and it maps cleanly on both models when you decode real VINs through vPIC, though the story differs by generation.
1st-gen Encore (CJ), position 8:
| Char | Engine | Notes |
|---|---|---|
| B | 1.4L Turbo I4, LUV (port injection, first-gen Ecotec Family 0) | The original launch engine, standard across most trims from 2013 |
| M | 1.4L Turbo I4, LE2 (direct injection, newer design) | Debuted on the 2016 Sport Touring trim, then spread to the rest of the lineup |
Both engines displace 1.4 liters and both are turbocharged, so displacement alone won’t tell you which one a given Encore has; the position-8 character tracks the engine family, not the size. The switchover wasn’t a single clean model-year cutoff, either: GM Authority reported that when the LE2 finally became the standard engine across the lineup, some early-production 2021 Encores still left the factory with the older LUV, built before the changeover took effect mid-year. Decode the full VIN if you need certainty rather than guessing from the model year alone.
2nd-gen Encore GX (MM), position 8:
| Char | Engine | Notes |
|---|---|---|
| 2 | 1.2L Turbo I3, L1H | Base engine on Preferred/Select trims, FWD, CVT; the 2020 launch engine |
| L | 1.3L Turbo I3, L3T | Higher-output engine on Select, Essence, and later trims, available FWD or AWD, 9-speed automatic |
This one is a clean, single-character split, confirmed across VINs from model years 2020 through 2023 in vPIC: every 2 at position 8 decodes to the 1.2L L1H, and every L decodes to the 1.3L L3T, regardless of trim, drivetrain, or year.
Position 9: Check digit
A single character calculated from the other 16 using a fixed weighting table and modulo-11 math. Change any one character in the VIN and the check digit stops matching. Every VIN cited in this guide was verified against NHTSA’s vPIC decoder, which flags a bad check digit as an error.
Position 10: Model year
The 10th character maps to model year on a 30-year cycle, the same standard used across the industry:
| Char | Year | Char | Year |
|---|---|---|---|
| 3 | 2033 | K | 2019 |
| 2 | 2032 | J | 2018 |
| 1 | 2031 | H | 2017 |
| Y | 2030 | G | 2016 |
| X | 2029 | F | 2015 |
| W | 2028 | E | 2014 |
| V | 2027 | D | 2013 |
| T | 2026 | C | 2012 |
| S | 2025 | B | 2011 |
| R | 2024 | A | 2010 |
| P | 2023 | 9 | 2009 |
| N | 2022 | 8 | 2008 |
| M | 2021 | 7 | 2007 |
| L | 2020 | 6 | 2006 |
I, O, and Q are never used in any VIN, since they’re too easily confused with 1 and 0. A CJ Encore only ever carries D (2013) through N (2022); an MM Encore GX only ever carries L (2020) onward. If a VIN pairs a model code with a year outside that model’s real production run, something is wrong with the number.
Position 11: Assembly plant
| Char | Plant | Notes |
|---|---|---|
| B | Bupyeong, South Korea (GM Korea) | Confirmed on every Encore and Encore GX decoded for this guide, both generations |
Every Encore and Encore GX sold in the US has come from the same factory. If you ever see a KL4 VIN with a different plant character at position 11, verify it carefully with the tool above before trusting the listing.
Positions 12-17: Serial number
The final six characters are the production sequence number for that specific vehicle. Combined with the previous 11 characters, they make every Encore and Encore GX VIN globally unique, even between two identical trims built the same week at the same plant.
Encore and Encore GX trim levels by generation
1st-gen Encore (CJ, 2013-2022): Trim names shifted several times over the model’s decade on sale. Early cars (2013-2015) came as Base, Convenience, Leather, and Premium. Buick added the Sport Touring (ST) trim for 2016, introducing the LE2 engine before it became standard elsewhere in the lineup. By its final year, 2022, the lineup had been trimmed down to a single trim, Preferred, offered with front- or all-wheel drive.
2nd-gen Encore GX (MM, 2020-present): Launched for 2020 with Preferred, Select, and Essence, plus an optional Sport Touring appearance package, and that three-trim structure carried through the following model years. For 2026, Buick reshuffled the naming again, moving to Preferred, Sport Touring, and Avenir, with Avenir now the top luxury trim.
None of these trim names are spelled out directly in the VIN. The decoder above reconstructs the trim from the VDS string plus the vehicle’s equipment record.
Where to find the VIN on a Buick Encore
- Lower-left corner of the windshield, visible from outside the car
- Driver’s side door jamb sticker (VIN, tire pressure, paint, and trim codes)
- Stamped on the engine bay firewall or front frame rail
- Vehicle title, registration, and Buick Owner Center account
The windshield and door jamb are the fastest to check on a used-car lot. If you suspect a cloned VIN, compare those against the frame-rail stamp, since a physical stamp is far harder to swap than an adhesive label.
Buick Encore recalls and safety
Recall history differs by generation and, within the 1st-gen Encore, by model year:
- 1st-gen Encore, 2014-2017: Caught up in GM’s 2016 sensing and diagnostic module (SDM) software recall, which affected millions of GM vehicles across several brands. Faulty SDM software could prevent frontal airbags and seatbelt pretensioners from deploying in a crash.
- 1st-gen Encore, 2019-2020: NHTSA campaign 20V668 covered certain Encores with the start/stop transmission accumulator, where missing or loose endcap bolts could allow a transmission fluid leak that, in the presence of an ignition source, raised the risk of fire. The remedy was a dealer inspection and, where needed, accumulator replacement.
- 2nd-gen Encore GX, 2020: GM recalled certain 2020 Encore GX vehicles because the rear attachment bolts on one or both front seats may not have been installed at the factory, and separately recalled 2020-2021 units over sensor contamination in the electronic brake boost system.
- 2nd-gen Encore GX, 2020-2022: GM recalled certain units over the emergency jack, which could fracture during use if not positioned exactly as directed in the owner’s manual.
To check your specific Encore or Encore GX:
- Decode the VIN with the tool above to confirm the exact model and model year
- 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 Encore 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, plant of origin, and any open NHTSA recalls. No sign-up.
What’s the difference between the Buick Encore and the Buick Encore GX?
They’re two different vehicles, not a base and upgraded version of the same car. The original Encore (2013-2022) rides on GM’s Gamma II platform and carries the VIN code CJ at positions 4-5. The Encore GX (2020-present) rides on the newer VSS-F platform, is larger, offers different engines, and carries the VIN code MM. Buick sold both side by side from 2020 through 2022 before discontinuing the original, smaller Encore.
How can I tell which Encore generation I have from the VIN?
Look at positions 4-5. CJ is the original, smaller Encore (2013-2022). MM is the Encore GX (2020-present). Position 10 then confirms the exact model year, and position 8 tells you the engine within that generation.
Where is the VIN on a Buick Encore?
The two easiest spots are the lower-left corner of the windshield, readable from outside the car, and the driver-side door jamb sticker. Both are required by federal labeling regulation. The frame rail near the engine bay carries a physical stamp of the same number.
Is the Buick Encore VIN decoder free?
Yes. VinDecoderPlus decodes every Encore and Encore GX VIN free of charge with no sign-up. A full vehicle history report (accident records, odometer history, prior ownership, salvage status) is available as an optional paid upgrade.
Can a Buick Encore VIN be faked?
The 17 characters can be retyped on a counterfeit plate, but the check digit at position 9 catches most single-character changes through math, and the frame-rail stamp is physically tied to the original car. If the windshield and door-jamb VINs match but the frame stamp doesn’t, the car may have been cloned. The guide how to check if a car is stolen by VIN walks through the verification steps.
