Buick Envision — D2XX, imported from China (first generation) (2016–2020)

The first-generation Envision is a compact crossover built at GM's plant in Yantai, China (GM Authority's 2017 page; Wikipedia) and sold in North America from the 2016 model year, when GM's order guide lists only the all-wheel-drive Premium I (1SN) and Premium II (1SP) with the turbo 2.0L LTG and the M2D 6 speed automatic. The 2017 guide adds the front- or all-wheel-drive Convenience (1SD) and Leather (1SL) with the 2.5L LCV and MHG 6 speed automatic; the 2018 guide names them Preferred and Essence and adds the front-drive base Envision (1SV), and the 2019 guide pairs the LTG with the M3T 9 speed automatic. The NICB VIN manuals list the Envision in every year from 2016 (nicb2016-gm.txt p.156) to 2020 (nicb2020-gm.txt p.162). Rows for 2016 to 2019 come from GM's order guides for those years, the GM Authority copies in the archive, and each row cites the pages of every year's guide that prints the code [FD] (the 2016 and 2017 guides were both published March 25, 2016, the 2017 one under the heading "2016 Buick (2017) Envision"; the 2018 guide April 7, 2017; the 2019 guide May 4, 2018). Trim availability in Notes is given by equipment group code (O optional, S standard), from the latest guide that lists the code.

Gaps: no GM order guide or RPO list for 2020 was found, so 2020 rests on GM Authority's 2020 pages, which print codes only for the engines, transmissions, trim groups, two new paints and one wheel; the codes they do not print are not claimed for 2020. Dealer accessories and safety items that the guides sell only inside a package (Surround Vision UVH and front automatic braking UGN in KSG, and the LPO items inside PCH, PCK, PDD, PDH and SDE) have no rows (see the report's gaps).
