How to read a Cadillac CT6 VIN — every digit explained

Every Cadillac CT6 carries a unique 17-character VIN stamped at the factory. Each position is a code — together they spell out where, when and how your car was built. Here's exactly what every digit means.

FIG.02
1–3 · WMI1XX
4–8 · VDSCM826
9 · Check5
10 · YearR
11 · PlantA
12–17 · Serial004352
  • WMI (1–3) — country & manufacturer. Tells you it's a Cadillac and the country it was built in.
  • VDS (4–8) — model, body style, engine, trim & restraints. The 8th digit is the engine code.
  • Check digit (9) — a math check that proves the VIN is genuine.
  • Model year (10) — the year it was built (e.g. R = 2024, S = 2025).
  • Plant (11) — which factory assembled this CT6.
  • Serial (12–17) — the unique sequential production number.
17 CHARS·SOURCE SAE / ISO 3779 · NHTSA vPIC

Digits 4–17 — the engine code (8th), model-year letter (10th) and plant — follow the universal SAE standard, identical on every car. For the full year-code table (2001–2026), country codes and where the VIN is stamped on your CT6, see the complete guide to reading a VIN.

Power Train:automatic Transmission25V148000

What's wrong. General Motors LLC (GM) is recalling certain 2019-2020 Cadillac CT6, 2020-2021 CT4, CT5, and 2020-2022 Chevrolet Camaro vehicles equipped with a 10-speed transmission. The transmission may become damaged internally and cause the wheels to lock-up.

Risk. Wheel lock-up while driving increases the risk of a crash.

Fix. Dealers will install transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025. Owners may contact Cadillac customer service at 1-800-333-4223 or Chevrolet customer service at 1-800-222-1020. GM's number for this recall is N242480630.

What's wrong. General Motors LLC (GM) is recalling certain 2020 Cadillac CT6 vehicles equipped with dealer-installed accessory 20" x 8.50" wheels (RPO 5JO or SHH). The tire pressure monitoring system (TPMS) sensors use the incorrect wireless radio frequency and cannot illuminate the low pressure warning light when the tire pressure drops below the recommended level. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 138, "Tire Pressure Monitoring Systems."

Risk. Drivers may drive the vehicle with low tire pressure without a low tire pressure warning, negatively impacting the vehicle handling and increasing the risk of a crash.

Fix. GM will notify owners, and dealers will replace all four TPMS sensors with the correct sensors, free of charge. The recall began December 3, 2019. Owners may contact GM customer service at 1-586-596-1733. GM's number for this recall is N192279200.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 208, "Occupant Crash Protection."

Risk. If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.

Fix. GM will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018.

Risk. If the turn-signals do not automatically deactivate, the driver may fail to turn them off manually. An erroneous active turn-signal may mislead pedestrians and other drivers, increasing the risk of a crash.

Furthermore, if this specific error occurs, the vehicle's diagnostics will not illuminate the instrument cluster ESC and ABS malfunction warning lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 126, "Electronic Stability Control" and 135, "Light Vehicle Brake Systems."

Risk. If the driver operates the vehicle unaware that ESC and ABS are not functioning, there is an increased risk of a crash.

Fix. GM will notify owners, and dealers will reprogram the EBCM, free of charge. The recall began February 4, 2020.
