    GMC Terrain — Second generation (D2XX) (2018–2024)

    The second-generation Terrain is a compact crossover with front-wheel or all-wheel drive: the NICB VIN manuals list SL, SLE, SLT and Denali series from 2018 (the SL front-wheel drive only and not after 2021), SLE and SLT diesel series for 2018 to 2020, and an all-wheel-drive AT4 from 2022. The 2019 rows come from GM's 2019 Terrain order guide (published April 27, 2018; the copy GM Authority hosts, held in the repository as a factory document and cited [FD] by page), which lists the 1.5L turbo LYX with the 9 speed 9T45 automatic (M3U), and the 2.0L turbo LTG with the 9 speed 9T50 (M3H); it prints the 1.6L turbo diesel LH7 and its 6 speed automatic only as contents of the diesel equipment groups 3SB and 4SB, so the LH7's 2019 rests on GM Authority's 2020 changes page. The 2018 and 2020–2024 rows rest only on GM Authority's Terrain, color, model-year change and news pages (single-source), which add the 1.5L turbo LSD for 2023.

    Gaps: no GM option list for 2018 or 2020–2024 was found, so a code is claimed for those years only where a GM Authority page prints it for that year, or where the next year's changes page lists it as deleted, renamed or no longer available, which supports the year before; codes that merely carried over are not claimed. NICB 2020 still prints the diesel VIN series, while GM Authority's 2020 changes page says the diesel was dropped for 2020; no diesel code is claimed after 2019. Items the 2019 guide prints only as package contents (every availability mark "included and only available with" a package) have no rows: the Driver Alert Package II items (UHY, UEU, UHX, UE4, KSG, UKJ, TQ5), DWK (B26), IOU (Y29, Y3I), UFQ and UV2 (WPR), KU1, KU3 and KA6 (PS1), GGC (CWB), PJM, V22 and VWD (WJP), AP9 and CGY (PDD), VR2 (V92) and the LPO package items (RXX, RYQ, S4X, SJ9, RYT, S08, RZ9, VKU, VTB, S03, VAV, VLI, VRS, W2D); the package rows name them. The diesel items MHG, FXK, C32, K13, NDE and FHX, which the guide prints only as contents of the diesel equipment groups 3SB and 4SB (the "included in equipment group" mark), have no rows either. VR2 keeps its 2020 row from GM Authority's 2021 changes page.

    • [FD] gmc/2019-gmc-terrain-order-guide-copy-gm-authority.txt — 2019 GMC Terrain order guide (published April 27, 2018; the distribution updates run to the week of 4/30/2018), GM Authority copy: p.1–10 standard equipment, p.25–36 interior, p.37–42 exterior, p.43–45 mechanical, p.46 engine/axle, p.47 color and trim, p.48–51 OnStar/SiriusXM fleet options, p.54 wheels
    • No GM document for 2018 or 2020–2024 is in the repository, and there is no Heritage kit.

    Each 2019 row cites the pages whose line the code heads (trim groups: the page-1 group footnote and the color and trim page; paint and interior codes: the color and trim page); the guide's equipment-group, PEG stairstep, RPO-index and distribution-update pages are not cited, nor a line whose only availability mark is the "included in equipment group" symbol (the diesel groups 3SB and 4SB).
