Chevrolet Trailblazer — First generation (VSS-F) (2021–2027)

The Chevrolet Trailblazer is the subcompact crossover sold in LS, LT, RS and ACTIV series in front- and all-wheel drive (the NICB manuals also print an L series for 2022, 2023 and 2025, which the fleet guides do not list); the NICB VIN manuals list it from 2021 through 2026. The rows below come from the 2025, 2026 and 2027 GM Fleet Order Guides (the 2027 guide is titled Trailblazer Limited and lists ACTIV in all-wheel drive only): a 1.2L Ecotec turbo (LBP, front-wheel drive) and a 1.3L Ecotec turbo (L3T), a CVT (MRG) on front-wheel drive and a 9 speed automatic (M3F) on all-wheel drive. No factory list for 2021 to 2024 is in the archive, so those years rest on the NICB manuals alone and the 2025 to 2027 rows carry no earlier years. The guides share many codes with the Buick Encore GX and Envista docs, which this doc follows for shared codes.
