How a Cadillac Celestiq VIN is structured
Every Cadillac carries a standardized 17-character VIN. Using the sample format 1G6KD5RS4JU123456 (Sample 2018 Cadillac CT6 built at Detroit-Hamtramck Assembly.), here is what each position means:
| Position | Section | In sample | What it encodes |
|---|---|---|---|
| 1–3 | World Manufacturer Identifier (WMI) | 1G6 | Identifies Cadillac and the country/region of build (1G6, 1GY). |
| 4–8 | Vehicle Descriptor Section (VDS) | KD5RS | Manufacturer-defined: model family, engine, and body/series. The exact meaning varies by make and model year. |
| 9 | Check digit | 4 | A calculated value that validates the other 16 characters. |
| 10 | Model year | J | Encodes the model year on a standardized 30-year cycle. |
| 11 | Assembly plant | U | Identifies the factory that built the vehicle. |
| 12–17 | Sequential number | 123456 | The unique production serial for this specific unit. |
1G6 identifies Cadillac passenger cars (CT4, CT5). 1GY identifies Cadillac SUVs (Escalade, XT4, XT5, XT6, Lyriq). Decode your own VIN above for the exact values — the sample is illustrative of the format only.
Where Cadillac builds it
- Lansing, Michigan (CT4, CT5)
- Arlington, Texas (Escalade)
- Spring Hill, Tennessee (XT5, XT6, Lyriq)
- Fairfax, Kansas (XT4)
The 11th VIN character identifies which plant built a specific Celestiq; the assembly plant is one of the facts the decode confirms.
Sources, data & limitations
Data source: VIN decoding returns manufacturer-reported attributes from NHTSA's vPIC database; recall campaigns and owner complaints come from NHTSA. Manufacturer-submitted fields vary by model year and market. Coverage: recalls and complaints are matched to the decoded year and model and do not confirm that this individual VIN has an unrepaired recall — verify exact-VIN status with Cadillac or NHTSA. This free decoder does not include accident, title, odometer, or ownership history.

FAQ
What does a Cadillac Celestiq VIN decoder show?
Model year, trim level, engine and displacement, transmission, drive type, body style, and assembly plant for that exact Celestiq — from manufacturer-submitted NHTSA vPIC data. CarWhere also cross-references open recalls, federal owner complaints, and verified buyer transaction prices for the same year and model.
Where is the VIN on a Cadillac Celestiq?
Lower driver's-side corner of the windshield (visible from outside), the driver's door jamb sticker, the title, or the insurance card. 1G6 identifies Cadillac passenger cars (CT4, CT5). 1GY identifies Cadillac SUVs (Escalade, XT4, XT5, XT6, Lyriq).
Is the Cadillac Celestiq VIN decoder free?
Yes — free, no account, no lookup limit. The optional $9.99 Full VIN Report adds the original window sticker (where Cadillac publishes one), itemized factory options, a recall and complaint scan, and a market price check with a negotiation target.
Can I check Celestiq recalls and problems by VIN?
Yes — at the model level. Decoding the VIN pins the exact year and model, and CarWhere surfaces the open NHTSA recall campaigns and federal owner complaints filed for that year/model — useful for spotting known trouble areas before buying a used Celestiq. A campaign match does not by itself confirm this individual VIN has an unrepaired recall; verify exact-VIN status through NHTSA or a Cadillac dealer (recall repairs are free for eligible vehicles).
